Plasenzotti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flow property of human blood is one of the important factors on the prevention of the circulatory condition such as a high blood pressure, a diabetes mellitus, and a cardiac infarction. However, the measurement of flow property of human blood, especially blood viscosity, is not so easy, because of their coagulation or aggregation behaviors after taking a sample from blood vessel. In the experiment, some kinds of anticoagulant were added into the human blood to avoid its solidification. Anticoagulant used in the blood test has been chosen for each purpose of blood test, for anticoagulant effect on blood is different mechanism for each. So that, there is a problem that the evaluation of measured blood property with different anticoagulant is so difficult. Therefore, it is so important to make clear the difference of anticoagulant effect on the blood property. In the previous work, a compact-size falling needle rheometer (FNR) has been developed in order to measure the flow property of human blood such as a flow curve, an apparent viscosity. It was found that FNR system can apply to a rheometer or a viscometry for various experimental conditions for not only human blood but also mammalians blood. In this study, the measurements of human blood viscosity with different anticoagulant (EDTA and Heparin) were carried out using newly developed FNR system. The effect of anticoagulant on blood viscosity was also tested by using the standard liquid for each. The accuracy on the viscometry was also tested by using the standard liquid for calibrating materials (JS-10, JS-20) and observed data have satisfactory agreement with reference data around 1.0% at 310K. The flow curve of six males and females with different anticoagulant were measured using FNR. In this experiment, EDTA and Heparin were chosen as anticoagulant for blood. Heparin can inhibit the coagulation of human blood by activating the body of anti-thrombin. To examine the effect of human blood viscosity on anticoagulant, flow curve was measured at high shear rate (＞350s-1), and apparent viscosity of each person were determined with different anticoagulant. The apparent viscosity of human blood with heparin was 2%-9% higher than that with EDTA. However, the difference of blood viscosity for two anticoagulants for same blood was different for each. Further discussion, we need the consideration of effect on other physical property, such as cellular component and plasma component. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=falling-needle%20rheometer" title="falling-needle rheometer">falling-needle rheometer</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20blood" title=" human blood"> human blood</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=anticoagulant" title=" anticoagulant"> anticoagulant</a> </p> <a href="https://publications.waset.org/abstracts/35527/evaluation-of-different-anticoagulant-effects-on-flow-properties-of-human-blood-using-falling-needle-rheometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Quality of Life of Patients on Oral Anticoagulant Therapy in Outpatient Cardiac Department Dr. Hasan Sadikin Central General Hospital Bandung</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mochammad%20Indra%20Permana">Mochammad Indra Permana</a>, <a href="https://publications.waset.org/abstracts/search?q=Andhiani%20Sharfina%20Arnellya"> Andhiani Sharfina Arnellya</a>, <a href="https://publications.waset.org/abstracts/search?q=Dika%20Pramita%20Destiani"> Dika Pramita Destiani</a>, <a href="https://publications.waset.org/abstracts/search?q=Budhi%20Prihartanto"> Budhi Prihartanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cardiovascular disease is the cause of the highest mortality rates in the world. The number of cardiovascular disease patients is increasing every year. Data obtained from World Health Organization (WHO) that 17,5 million people died from this disease. The condition of cardiovascular diseases such as atrial fibrillation, myocardial infarction, venous thromboembolism, and several other conditions need anticoagulant therapy. Results of the anticoagulant therapy are measured not only by the effectiveness of International Normalized Ratio (INR) value but also by the quality of life of the patients. The purpose of this study was to determine the quality of life of patients on oral anticoagulant therapy in outpatient cardiac department Dr. Hasan Sadikin central general hospital, Bandung, Indonesia. This is a cross-sectional study with collecting data from the quality of life questionnaire and medical record of the patients. The results of this study showed that 28 patients (46,7%) had a good quality of life, 30 patients (50%) had a moderate quality of life, and 2 patients (3,3%) had a poor quality of life with no significant differences in quality of life based on age, gender, diagnosis, and duration of drug use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticoagulant" title="anticoagulant">anticoagulant</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20diseases" title=" cardiovascular diseases"> cardiovascular diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=INR" title=" INR"> INR</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/58096/quality-of-life-of-patients-on-oral-anticoagulant-therapy-in-outpatient-cardiac-department-dr-hasan-sadikin-central-general-hospital-bandung" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58096.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Field Efficacy Evaluation and Synergistic Effect of Two Rodenticides Zinc Phosphide and Brodifacoum against Field Rats of the Pothwar Region, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadeem%20Munawar">Nadeem Munawar</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Galbraith"> David Galbraith</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Mahmood"> Tariq Mahmood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rodenticides are often included as part of an integrated pest management approach for managing rodent species since they are relatively quick and inexpensive to apply. The current field study was conducted to evaluate the effectiveness of formulated baits of zinc phosphide (2%) and the second generation anticoagulant brodifacoum (0.005%) against field rats inhabiting a wheat-groundnut cropping system. Burrow baiting was initiated at the early flowering stages of the respective crops, and continued through three growth stages (tillering / peg formation, flowering, and maturity). Three treatments were done at equal time intervals, with the final baiting being about 2 weeks before harvest. Treatment efficacy of the trials was assessed through counts of active rodent burrows before and after treatments at the three growth stages of these crops. The results indicated variable degrees of reduction in burrow activities following the three bait applications. The reductions in rodent activity in wheat were: 88.8% (at tillering), 92%, (at flowering/grain formation), and 95.5% (at maturity). In groundnut, the rodent activities were reduced by 91.8%, 93.5% and 95.8% at sowing, peg formation, and maturity stages, respectively. The estimated mortality at all three growth stages of both wheat and groundnut ranged between 60-85%. We recommend that a field efficacy study should be conducted with zinc phosphide and brodifacoum bait formulations to determine their field performance in the reduction of agricultural damage by rodent pest species. It is a promising alternative approach for use of the most potent second-generation anticoagulant (brodifacoum) in resistance management, particularly with respect to reducing environmental risks and secondary poisoning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brodifacoum" title="brodifacoum">brodifacoum</a>, <a href="https://publications.waset.org/abstracts/search?q=burrow%20baiting" title=" burrow baiting"> burrow baiting</a>, <a href="https://publications.waset.org/abstracts/search?q=second-generation%20anticoagulant" title=" second-generation anticoagulant"> second-generation anticoagulant</a>, <a href="https://publications.waset.org/abstracts/search?q=synergistic%20effect" title=" synergistic effect "> synergistic effect </a> </p> <a href="https://publications.waset.org/abstracts/107872/field-efficacy-evaluation-and-synergistic-effect-of-two-rodenticides-zinc-phosphide-and-brodifacoum-against-field-rats-of-the-pothwar-region-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107872.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> A Promising Thrombolytic and Anticoagulant Serine Protease Purified from Lug Worms Inhabiting Tidal Flats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hye%20Jin%20Kim">Hye Jin Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwa%20Sung%20Shin"> Hwa Sung Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ischemic stroke means the caused brain damage due to neurological defects, occurring occlusion of cerebral vascular resulting in thrombus or embolism. t-PA (tissue Plasminogen Activator) is the only thrombolytic agent passed the FDA (Food and Drug Administration). However, t-PA directly dissolves the thrombus (direct activity) through fibrinolysis, showing side effects such as re-occlusion. In this study, we evaluated the thrombolytic activities of the serine protease extracted from lugworms inhabiting tidal flats. The new serine protease identified as 38 kDa by SDS-PAGE was not toxic to brain endothelial cells line (hCMEC/D3). Also, the plasmin synthesis inhibition activity (indirect activity) of the new serine protease was confirmed through fibrin zymography assay and fibrin plate assay. It was higher than direct activity as compared to u-PA (urokinase Plasminogen Activator). The activities were found to be maintained at a wide range of temperature (4-70 ℃) and pH 7-10 compared to previous thrombolytic agents from the azocasein assay. In addition, the new serine protease has shown anticoagulant activity from fibrinogenolytic activity assay. In conclusion, the serine protease in lug worms inhabiting the tidal flats could be considered a promising thrombolytic candidate for the treatment of ischemic stroke. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline%20serine%20protease" title="alkaline serine protease">alkaline serine protease</a>, <a href="https://publications.waset.org/abstracts/search?q=bifunctional%20thrombolytic%20activity" title=" bifunctional thrombolytic activity"> bifunctional thrombolytic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=fibrinolytic%20activity" title=" fibrinolytic activity"> fibrinolytic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemic%20stroke" title=" ischemic stroke"> ischemic stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=lug%20worms" title=" lug worms"> lug worms</a> </p> <a href="https://publications.waset.org/abstracts/75882/a-promising-thrombolytic-and-anticoagulant-serine-protease-purified-from-lug-worms-inhabiting-tidal-flats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75882.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Haematological Correlates of Ischemic Stroke and Transient Ischemic Attack: Lessons Learned </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Himali%20Gunasekara">Himali Gunasekara</a>, <a href="https://publications.waset.org/abstracts/search?q=Baddika%20Jayaratne"> Baddika Jayaratne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Haematological abnormalities are known to cause Ischemic Stroke or Transient Ischemic Attack (TIA). The identification of haematological correlates plays an important role in a management and secondary prevention. The objective of this study was to describe haematological correlates of stroke and their association between stroke profile. The haematological correlates screened were Lupus Anticoagulant, Dysfibroginemia, Paroxysmal nocturnal haemoglobinurea (PNH), Sickle cell disease, Systemic Lupus Erythematosis (SLE) and Myeloploriferative Neoplasms (MPN). A cross sectional descriptive study was conducted in a sample of 152 stroke patients referred to haematology department of National Hospital of Sri Lanka for thrombophilia screening. Different tests were performed to assess each hematological correlate. Diluted Russels Viper Venom Test and Kaolin clotting time were done to assess Lupus anticoagulant. Full blood count (FBC), blood picture, Sickling test and High Performance Liquid Chromatography were the tests used for detection of Sickle cell disease. Paroxysmal nocturnal haemoglobinurea was assessed by FBC, blood picture, Ham test and Flowcytometry. FBC, blood picture, Janus Kinase 2 (V617F) mutation analysis, erythropoietin level and bone marrow examination were done to look for the Myeloproliferative neoplasms. Dysfibrinogenaemia was assessed by TT, fibrinogen antigen test, clot observation and clauss test. Anti nuclear antibody test was done to look for systemic lupus erythematosis. Among study sample, 134 patients had strokes and only 18 had TIA. The recurrence of stroke/TIA was observed in 13.2% of patients. The majority of patients (94.7%) have had radiological evidence of thrombotic event. One fourth of patients had past thrombotic events while 12.5% had family history of thrombosis. Out of haematological correlates screened, Lupus anticoagulant was the commonest haematological correlate (n=16 ) and dysfibrigonaemia(n=11 ) had the next high prevalence. One patient was diagnosed with Essential thrombocythaemia and one with SLE. None of the patients were positive for screening tests done for sickle cell disease and PNH. The Haematological correlates were identified in 19% of our study sample. Among stroke profile only presence of past thrombotic history was statistically significantly associated with haematological disorders (P= 0.04). Therefore, hematological disorders appear to be an important factor in etiological work-up of stroke patients particularly in patients with past thrombotic events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stroke" title="stroke">stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20ischemic%20attack" title=" transient ischemic attack"> transient ischemic attack</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20correlates" title=" hematological correlates"> hematological correlates</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20disorders" title=" hematological disorders"> hematological disorders</a> </p> <a href="https://publications.waset.org/abstracts/53563/haematological-correlates-of-ischemic-stroke-and-transient-ischemic-attack-lessons-learned" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53563.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">236</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Novel Oral Anticoagulants (NOACS) Adherence and Bleeding Events in Atrial Fibrillation Patients: A Systematic Review and Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tadesse%20Melaku%20Abegaz">Tadesse Melaku Abegaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Akshaya%20Srikanth%20Bahagavathula"> Akshaya Srikanth Bahagavathula</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulla%20Shehab%20Sheab"> Abdulla Shehab Sheab</a>, <a href="https://publications.waset.org/abstracts/search?q=Asim%20Hassen"> Asim Hassen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: Non-adherence and discontinuation of anticoagulant therapy lead to increased ischemic stroke risk and contributes to suboptimal outcomes of the anticoagulant treatment. This systematic review and meta-analysis were aimed to investigate the adherence to NOACs and adverse events in patients with AF. Methods: Original research articles conducted on patients with AF and using any NOACs (dabigatran, rivoraxaban and apixaban) reporting adherence for at least 35 days were included. Scientific databases including PubMed, Web of Science, and Google Scholar were searched using MeSH keywords to obtaining literature researched between 2008 to till June, 2016. Study characteristics, patient’s sociodemographic and clinical characteristics, medication adherence levels and bleeding events reported were recorded. Results: The overall sample size of the six studies is 1,640,157, with CHADS2 scores < 2 in 551 patients, CHADS2-VASc ≥ 2 in 62,232 AF patients. Three-forth [75.6% (95%CI= 66.5-84.8), p < 0.001] are adherent to NOACs. However, a higher rate [72.7% (62.5-82.9), p < 0.001] of adherence was observed with Dabigatran than Apixaban [59.9% (3.2-123.1), p=0.063] and Rivaroxaban [59.3% (38.7-80.0), p<0.001]. Sub-group analysis revealed that nearly 57% of the AF patients on NOACs have CHADS2 scores < 2 and 20% of these patients were non-adherent to NOACs. Overall bleeding events rate associated with NOACs non-adherent AF patients was found to be 7.5% (0.2-14.8), p=0.045. However, nearly 11.2% of AF patients experienced bleeding events were non-adherent to NOAC medications. A higher proportion of bleeding events were noticed with Dabigatran (14.7%). Conclusions: Adherence rates, while uniformly suboptimal, nevertheless varied considerably, lowest at 59.3% for rivaroxaban and 59.9% for apixaban, followed by dabigatran (75.6%). Overall bleeding events associated with NOACs rates were 7.5%. However, lower adherence to NOACs was associated with worse outcomes among patients with greater stroke risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atrial%20fibrillation" title="atrial fibrillation">atrial fibrillation</a>, <a href="https://publications.waset.org/abstracts/search?q=bleeding%20events" title=" bleeding events"> bleeding events</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title=" meta-analysis"> meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=novel%20oral%20anticoagulants" title=" novel oral anticoagulants"> novel oral anticoagulants</a> </p> <a href="https://publications.waset.org/abstracts/62559/novel-oral-anticoagulants-noacs-adherence-and-bleeding-events-in-atrial-fibrillation-patients-a-systematic-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62559.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">340</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Aspirin Loaded Poly-L-Lactic Acid Nanofibers and Their Potentials as Small Diameter Vascular Grafts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahboubeh%20Kabiri">Mahboubeh Kabiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Aslani"> Saba Aslani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among various approaches used for the treatment of cardiovascular diseases, the occlusion of the small-diameter vascular graft (SDVG) is still an unresolved problem which seeks further research to address them. Though autografts are now the gold standards to be replaced for blocked coronary arteries, they suffer from inadequate quality and quantity. On the other hand, the major problems of the tissue engineered grafts are thrombosis and intimal hyperplasia. Provision of a suitable spatiotemporal release pattern of anticoagulant agents such as heparin and aspirin can be a step forward to overcome such issues . Herein, we fabricated electrospun scaffolds from FDA (Food and Drug Administration) approved poly-L-lactic acid (PLLA) with aspirin loaded into the nanofibers. Also, we surface coated the scaffolds with Amniotic Membrane lysate as a source for natural elastic polymers and a mimic of endothelial basement membrane. The scaffolds were characterized thoroughly structurally and mechanically for their morphology, fiber orientation, tensile strength, hydrophilicity, cytotoxicity, aspirin release and cell attachment support. According to the scanning electron microscopy (SEM) images, the size of fibers ranged from 250 to 500 nm. The scaffolds showed appropriate tensile strength expected for vascular grafts. Cellular attachment, growth, and infiltration were proved using SEM and MTT (3-(4,5-Dimethylthiazol-2-Yl)-2,5-Diphenyltetrazolium Bromide) assay. Drug-loaded scaffolds showed a sustained release profile of aspirin in 7 days. An enhanced cytocompatibility was observed in AM-coated electrospun PLLA fibers compared to uncoated scaffolds. Our results together indicated that AM lysate coated ASA releasing scaffolds have promising potentials for development of a biocompatible SDVG. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vascular%20tissue%20engineering" title="vascular tissue engineering">vascular tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular%20grafts" title=" vascular grafts"> vascular grafts</a>, <a href="https://publications.waset.org/abstracts/search?q=anticoagulant%20agent" title=" anticoagulant agent"> anticoagulant agent</a>, <a href="https://publications.waset.org/abstracts/search?q=aspirin" title=" aspirin"> aspirin</a>, <a href="https://publications.waset.org/abstracts/search?q=amniotic%20membrane" title=" amniotic membrane"> amniotic membrane</a> </p> <a href="https://publications.waset.org/abstracts/97597/aspirin-loaded-poly-l-lactic-acid-nanofibers-and-their-potentials-as-small-diameter-vascular-grafts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> In vivo Determination of Anticoagulant Property of the Tentacle Extract of Aurelia aurita (Moon Jellyfish) Using Sprague-Dawley Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bea%20Carmel%20H.%20Casiding">Bea Carmel H.

Recent studies have verified the prevention of blood clotting properties of the moon jellyfish tentacle extract through in vitro methods. The purpose of this study was to validate the blood clotting ability of A. aurita tentacle extract using in vivo method of experimentation. The tentacles of A. aurita jellyfish were excised and filtered then centrifuged at 3000xg for 10 minutes. The crude nematocyst extract was suspended in 1:6 ratios with phosphate buffer solution and sonicated for three periods of 20 seconds each at 50 Hz. Protein concentration of the extract was determined using Bradford Assay. Bovine serum albumin was the standard solution used with the following concentrations: 35.0, 70.0, 105.0, 140.0, 175.0, 210.0, 245.0, and 280.0 µg/mL. The absorbance was read at 595 nm. Toxicity testing from OECD guidelines was adapted. The extract suspended in phosphate-buffered saline solution was arbitrarily set into three doses (0.1mg/kg, 0.3mg/kg, 0.5mg/kg) and were administered daily for five days to the experimental groups of five male Sprague-Dawley rats (one dose per group). Before and after the administration period, bleeding time and clotting time tests were performed. The One-way Analysis of Variance (ANOVA) was used to analyze the difference of before and after bleeding time and clotting time from the three treatment groups, time, positive and negative control groups. The average protein concentration of the sonicated crude tentacle extract was 206.5 µg/mL. The highest dose administered (0.5mg/kg) produced significant increase in the time for both bleeding and clotting tests. However, the preceding lower dose (0.3mg/kg) only was significantly effective for clotting time test. The protein contained in the tentacle extract with a concentration of 206.5 mcg/mL and dose of 0.3 mg/kg and 0.5 mg/kg of A. aurita elicited anticoagulating activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticoagulant" title="anticoagulant">anticoagulant</a>, <a href="https://publications.waset.org/abstracts/search?q=bleeding%20time%20test" title=" bleeding time test"> bleeding time test</a>, <a href="https://publications.waset.org/abstracts/search?q=clotting%20time%20test" title=" clotting time test"> clotting time test</a>, <a href="https://publications.waset.org/abstracts/search?q=moon%20jellyfish" title=" moon jellyfish"> moon jellyfish</a> </p> <a href="https://publications.waset.org/abstracts/39662/in-vivo-determination-of-anticoagulant-property-of-the-tentacle-extract-of-aurelia-aurita-moon-jellyfish-using-sprague-dawley-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39662.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Prevalence and Clinical Significance of Antiphospholipid Antibodies in COVID-19 Patients Admitted to Intensive Care Units</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Najim">Mostafa Najim</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Rahhal"> Alaa Rahhal</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadi%20Khir"> Fadi Khir</a>, <a href="https://publications.waset.org/abstracts/search?q=Safae%20Abu%20Yousef"> Safae Abu Yousef</a>, <a href="https://publications.waset.org/abstracts/search?q=Amer%20Aljundi"> Amer Aljundi</a>, <a href="https://publications.waset.org/abstracts/search?q=Feryal%20Ibrahim"> Feryal Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Aliaa%20Amer"> Aliaa Amer</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Soliman%20Mohamed"> Ahmed Soliman Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Samira%20Saleh"> Samira Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dekra%20Alfaridi"> Dekra Alfaridi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mahfouz"> Ahmed Mahfouz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumaya%20Al-Yafei"> Sumaya Al-Yafei</a>, <a href="https://publications.waset.org/abstracts/search?q=Faraj%20Howady"> Faraj Howady</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Yahya%20%20Khatib"> Mohamad Yahya Khatib</a>, <a href="https://publications.waset.org/abstracts/search?q=Samar%20Alemadi"> Samar Alemadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Coronavirus disease 2019 (COVID-19) increases the risk of coagulopathy among critically ill patients. Although the presence of antiphospholipid antibodies (aPLs) has been proposed as a possible mechanism of COVID-19 induced coagulopathy, their clinical significance among critically ill patients with COVID-19 remains uncertain. Methods: This prospective observational study included patients with COVID-19 admitted to intensive care units (ICU) to evaluate the prevalence and clinical significance of aPLs, including anticardiolipin IgG/IgM, anti-β2-glycoprotein IgG/IgM, and lupus anticoagulant. The study outcomes included the prevalence of aPLs, a primary composite outcome of all-cause mortality, and arterial or venous thrombosis among aPLs positive patients versus aPLs negative patients during their ICU stay. Multiple logistic regression was used to assess the influence of aPLs on the primary composite outcome of mortality and thrombosis. Results: A total of 60 critically ill patients were enrolled. Of whom, 57 (95%) were male, with a mean age of 52.8 ± 12.2 years, and the majority were from Asia (68%). Twenty-two patients (37%) were found to have positive aPLs; of whom 21 patients were positive for lupus anticoagulant, whereas one patient was positive for anti-β2-glycoprotein IgG/IgM. The composite outcome of mortality and thrombosis during ICU did not differ among patients with positive aPLs compared to those with negative aPLs (4 (18%) vs. 6 (16%), aOR= 0.98, 95% CI 0.1-6.7; p-value= 0.986). Likewise, the secondary outcomes, including all-cause mortality, venous thrombosis, arterial thrombosis, discharge from ICU, time to mortality, and time to discharge from ICU, did not differ between those with positive aPLs upon ICU admission in comparison to patients with negative aPLs. Conclusion: The presence of aPLs does not seem to affect the outcomes of critically ill patients with COVID-19 in terms of all-cause mortality and thrombosis. Therefore, clinicians may not screen critically ill patients with COVID-19 for aPLs unless deemed clinically appropriate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiphospholipid%20antibodies" title="antiphospholipid antibodies">antiphospholipid antibodies</a>, <a href="https://publications.waset.org/abstracts/search?q=critically%20ill%20patients" title=" critically ill patients"> critically ill patients</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulopathy" title=" coagulopathy"> coagulopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=coronavirus" title=" coronavirus"> coronavirus</a> </p> <a href="https://publications.waset.org/abstracts/131723/prevalence-and-clinical-significance-of-antiphospholipid-antibodies-in-covid-19-patients-admitted-to-intensive-care-units" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Impact of Climate Change on Some Physiological Parameters of Cyclic Female Egyptian Buffalo </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Abu-Heakal">Nabil Abu-Heakal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Abo-Ghanema"> Ismail Abo-Ghanema</a>, <a href="https://publications.waset.org/abstracts/search?q=Basma%20Hamed%20Merghani"> Basma Hamed Merghani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this investigation is to study the effect of seasonal variations in Egypt on hematological parameters, reproductive and metabolic hormones of Egyptian buffalo-cows. This study lasted one year extending from December 2009 to November 2010 and was conducted on sixty buffalo-cows. Group of 5 buffalo-cows at estrus phase were selected monthly. Then, after blood sampling through tail vein puncture in the 2nd day after natural service, they were divided in two samples: one with anticoagulant for hematological analysis and the other without anticoagulant for serum separation. Results of this investigation revealed that the highest atmospheric temperature was in hot summer 32.61±1.12°C versus 26.18±1.67°C in spring and 19.92±0.70°C in winter season, while the highest relative humidity % was in winter season 43.50±1.60% versus 32.50±2.29% in summer season. The rise in temperature-humidity index from 63.73±1.29 in winter to 78.53±1.58 in summer indicates severe heat stress which is associated with significant reduction in total red blood cell count (3.20±0.15×106), hemoglobin concentration (8.83±0.43 g/dl), packed cell volume (30.73±0.12%), lymphocytes % (40.66±2.33 %), serum progesterone hormone concentration (0.56±0.03 ng/mll), estradiol17-B concentration (16.8±0.64 ng/ml), triiodothyronin (T3) concentration (2.33±0.33 ng/ml) and thyroxin hormone (T4) concentration (21.66±1.66 ng/ml), while hot summer resulted in significant increase in mean cell volume (96.55±2.25 fl), mean cell hemoglobin (30.81±1.33 pg), total white blood cell count (10.63±0.97×103), neutrophils % (49.66±2.33%), serum prolactin hormone (PRL) concentration (23.45±1.72 ng/ml) and cortisol hormone concentration (4.47±0.33 ng/ml) compared to winter season. There was no significant seasonal variation in mean cell hemoglobin concentration (MCHC). It was concluded that in Egypt there was a seasonal variation in atmospheric temperature, relative humidity, temperature humidity index (THI) and the rise in THI above the upper critical level (72 units), which, for lactating buffalo-cows in Egypt is the major constraint on buffalo-cows' hematological parameters and hormonal secretion that affects animal reproduction. Hence, we should improve climatic conditions inside the dairy farm to eliminate or reduce summer infertility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffalo" title="buffalo">buffalo</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20parameters" title=" physiological parameters"> physiological parameters</a> </p> <a href="https://publications.waset.org/abstracts/8740/impact-of-climate-change-on-some-physiological-parameters-of-cyclic-female-egyptian-buffalo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8740.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">660</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Haemobiogram after Intramuscular Administration of Amoxicillin to Sheep</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amer%20Elgerwi">Amer Elgerwi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelrazzag%20El-Magdoub"> Abdelrazzag El-Magdoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Abubakr%20El-Mahmoudy"> Abubakr El-Mahmoudy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are many bacterial infections affecting sheep that necessitates antibiotic intervention. Amoxicillin is among commonly used antibiotics in such case for its broad spectrum of activity. However, the side alterations in blood and organ function that may be associated during or after treatment are questionable. Therefore, the aim of the present study was to assess the possible alterations in blood parameters and organ function bio markers of sheep that may occur following intramuscular injection of amoxicillin. Amoxicillin has been administered intramuscularly to 10 sheep at a dosage regimen of 7 mg/kg of body weight for 5 successive days. Two types of blood samples (with and without anticoagulant) were collected from the jugular vein pre- and post-administration of the drug. Amoxicillin significantly (P < 0.001) increased total leukocyte count and (P < 0.05) absolute eosinophilic count when compared with those of the control samples. Aspartate aminotransferase, alkaline phosphatase and cholesterol were significantly (P < 0.05) higher than the corresponding control values. In addition, amoxicillin significantly (P < 0.05) increased blood urea nitrogen and creatinine but decreased phosphorus level when compared with those of prior-administration samples. These data may indicate that although the side changes caused by amoxicillin are minor in sheep, yet the liver and kidney functions should be monitored during its usage in therapy and it should be used with care for treatment of sheep with renal and/or hepatic impairments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amoxicillin" title="amoxicillin">amoxicillin</a>, <a href="https://publications.waset.org/abstracts/search?q=biogram" title=" biogram"> biogram</a>, <a href="https://publications.waset.org/abstracts/search?q=haemogram" title=" haemogram"> haemogram</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep" title=" sheep"> sheep</a> </p> <a href="https://publications.waset.org/abstracts/18291/haemobiogram-after-intramuscular-administration-of-amoxicillin-to-sheep" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18291.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">458</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Synthesis of 2-Aminoisocoumarinoselenazoles via Transition Metal-Free Alkylation and Ru(II)-Catalyzed [4+2] Alkyne Annulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar">Sunil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Dhole"> Sandip Dhole</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Salunke"> Deepak Salunke</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-ming%20Sun"> Chung-ming Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heterocycles bearing nitrogen, oxygen, and selenium are present in innumerable biologically active compounds. For instance, coumarin containing dicoumarol acts as naturally occurring anticoagulant. 2-Acylamido selenazole works as Store-Operated Calcium (SOC) channel regulator. Therefore, due to biologically significance of selenazole and coumarin and our quest to develop efficient methodologies for the synthesis of complex heterocycles, the trisubstituted angular isocoumarinoselenazole synthesis was proposed and achieved by starting from nitrobenzoic acid derivative, available commercially. Synthetic procedure involves three steps: i) the construction of 2-aminobenzoselenazoles, ii) their regioselective N-alkylation at position-2 and iii) alkyne insertion via Ru catalyzed C-H activation. Transition metal free synthesis of benzoselenazoles was successfully brought about by the addition/elimination reaction via intramolecular C-Se bond formation. In the next step, N-alkylation of selenazole furnished two regioisomers. Both the isomers exhibited different reactivity towards [4+2] alkyne annulation reaction. The fusion of α-pyrone ring on the benzo[1,3-d]selenazole skeleton was achieved via Ru(II)-catalyzed C-H activation and alkyne insertion. As evident from mechanism, the selenazole 'N' plays an important role for the experiential selectivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkylation" title="alkylation">alkylation</a>, <a href="https://publications.waset.org/abstracts/search?q=alkyne%20insertion" title=" alkyne insertion"> alkyne insertion</a>, <a href="https://publications.waset.org/abstracts/search?q=coumarin" title=" coumarin"> coumarin</a>, <a href="https://publications.waset.org/abstracts/search?q=selenazole" title=" selenazole "> selenazole </a> </p> <a href="https://publications.waset.org/abstracts/125051/synthesis-of-2-aminoisocoumarinoselenazoles-via-transition-metal-free-alkylation-and-ruii-catalyzed-42-alkyne-annulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125051.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Natural Honey and Effect on the Activity of the Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abujnah%20Dukali">Abujnah Dukali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural honey was assessed in cell culture system for its anticancer activity. Human leukemic cell line HL 60 was treated with honey and cultured for 5 days and cytotoxicity was calculated by MTT assay. Honey showed cytotoxicity with CC50 value of 174.20 µg/ml. Radical modulation activities was assessed by lipid peroxidation assay using egg lecithin. Honey showed antioxidant activity with EC50 value of 159.73 µg/ml. In addition, treatment with HL60 cells also resulted in nuclear DNA fragmentation, as seen in agarose gel electrophoresis. This is a hallmark of cells undergoing apoptosis. Confirmation of apoptosis was performed by staining the cells with Annexin V and FACS analysis. Apoptosis is an active, genetically regulated disassembly of the cell form within. Disassembly creates changes in the phospholipid content of the cytoplasmic membrane outer leaflet. Phosphatidylserine (PS) is translocated from the inner to the outer surface of the cell for phagocytic cell recognition. The human anticoagulant, annexin V, is a Ca2+-dependent phospholipid protein with a high affinity for PS. Annexin V labeled with fluorescein can identify apoptotic cells in the population It is a confirmatory test for apoptosis. Annexin V-positive cells were defined as apoptotic cells. Since honey shows both antioxidant activity and cytotoxicity at almost the same concentration, it can prevent the free radical induced cancer as prophylactic agent and kill the cancer cells by apoptotic process as a chemotherapeutic agent. Everyday intake of honey can prevent the cancer induction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer" title="anticancer">anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=cells" title=" cells"> cells</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a> </p> <a href="https://publications.waset.org/abstracts/44196/natural-honey-and-effect-on-the-activity-of-the-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44196.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">206</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Budd-Chiari Syndrome: Common Presentation, Rare Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aadil%20Khan">Aadil Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Chomayil"> Yasser Chomayil</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20P.%20Venugopalan"> P.

The etiology remains idiopathic in 16% -35% of cases. Malignancy, rheumatological disorder, myeloproliferative disease, inheritable coagulopathy, infection or hyperestrogen state can be identified in many cases. Methodology: Review of case records of the patient presented to Aster Medcity, Emergency Department, Cochin. Introduction:17 years old female was presented to ED with fever, jaundice and abdominal distention since 1 week. O/E: Pallor+, icterus+. Abdomen- gross distension+, shifting dullness+, generalized anasarca+. USG abdomen showed hepatomegaly with mild coarse echotexture and moderate to gross ascites. CT abdomen and chest showed hepatomegaly with thrombosis of all three hepatic vein and moderate ascites suggestive of Budd-Chiari syndrome. Patient was taken for catheter vein thrombolysis. Venogram done the next day revealed almost > 50% opening of the right hepatic vein. Concurrent doppler showed colour and doppler signals in middle hepatic veins. She gradually improved and was discharged home on anticoagulant and adviced regular follow up. Conclusion: Being a rare disease in this young population, high suspicion is required when evaluating young patients with abdominal pain and jaundice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Budd-Chiari%20syndrome" title="Budd-Chiari syndrome">Budd-Chiari syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20disease" title=" rare disease"> rare disease</a>, <a href="https://publications.waset.org/abstracts/search?q=abdominal%20pain" title=" abdominal pain"> abdominal pain</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a> </p> <a href="https://publications.waset.org/abstracts/59334/budd-chiari-syndrome-common-presentation-rare-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59334.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Assessment of Hemostatic Activity of the Aqueous Extract of Leaves of Marrubium vulgare L.: A Mediterranean Lamiaceae Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Ghedadba">Nabil Ghedadba</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdessemed%20Samira"> Abdessemed Samira</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Hambaba"> Leila Hambaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Sidi%20Mohamed%20Ould%20Mokhtar"> Sidi Mohamed Ould Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Fercha"> Nassima Fercha</a>, <a href="https://publications.waset.org/abstracts/search?q=Houas%20Bousselsela"> Houas Bousselsela</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The overall objective of this study was to evaluate in vitro the hemostatic activity of secondary metabolites (polyphenols, flavonoids, and tannins) of Marrubium vulgare leaves, aromatic plant widely used in traditional medicine for the treatment of asthma, cough, diabetes (by its effect on the pancreas to secrete insulin), heart disease, fever has a high efficiency as against inflammation. Qualitative analysis of the aqueous extract (AQE) by thin layer chromatography revealed the presence of quercetin, kaempferol and rutin. Quantification of total phenols by Folin Ciocalteu method and flavonoids by AlCl3 method gave high values with AQE: 175±0.80 mg GAE per 100g of the dry matter, 23.86±0.36 mg QE per 100g of dry matter. Moreover, the assay of condensed tannins by the vanillin method showed that AQE contains the highest value: 16.55±0.03 mg e-catechin per 100 g of dry matter. Assessment of hemostatic activity by the plasma recalcification method (time of Howell) has allowed us to discover the surprising dose dependent anticoagulant effect of AQE lyophilized from leaves of M. vulgare. A positive linear correlation between the two parameters studied: the content of condensed tannins and hemostatic activity (r=0.96) were used to highlight a possible role of these compounds that are potent vasoconstrictor activity in hemostatic. From these results we can see that Marrubium vulgre could be used for the treatment of health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marrubium%20vulgare%20L." title="Marrubium vulgare L.">Marrubium vulgare L.</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20extract" title=" aqueous extract"> aqueous extract</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds%20dosing" title=" phenolic compounds dosing"> phenolic compounds dosing</a>, <a href="https://publications.waset.org/abstracts/search?q=hemostatic%20activity" title=" hemostatic activity"> hemostatic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=condensed%20tannins" title=" condensed tannins"> condensed tannins</a> </p> <a href="https://publications.waset.org/abstracts/10562/assessment-of-hemostatic-activity-of-the-aqueous-extract-of-leaves-of-marrubium-vulgare-l-a-mediterranean-lamiaceae-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10562.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">242</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Clinical Features of Acute Aortic Dissection Patients Initially Diagnosed with ST-Segment Elevation Myocardial Infarction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Jee%20Lee">Min Jee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Sun%20Park"> Young Sun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Shin%20Ahn"> Shin Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Hwan%20Sohn"> Chang Hwan Sohn</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Woo%20Seo"> Dong Woo Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Ho%20Lee"> Jae Ho Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoon%20Seon%20Lee"> Yoon Seon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung%20Soo%20Lim"> Kyung Soo Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Won%20Young%20Kim"> Won Young Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Acute myocardial infarction (AMI) concomitant with acute aortic syndrome (AAS) is rare but prompt recognition of concomitant AAS is crucial, especially in patients with ST-segment elevation myocardial infarction (STEMI) because misdiagnosis with early thrombolytic or anticoagulant treatment may result in catastrophic consequences. Objectives: This study investigated the clinical features of patients of STEMI concomitant with AAS that may lead to the diagnostic clue. Method: Between 1 January 2010 and 31 December 2014, 22 patients who were the initial diagnosis of acute coronary syndrome (AMI and unstable angina) and AAS (aortic dissection, intramural hematoma and ruptured thoracic aneurysm) in our emergency department were reviewed. Among these, we excluded 10 patients who were transferred from other hospital and 4 patients with non-STEMI, leaving a total of 8 patients of STEMI concomitant with AAS for analysis. Result: The mean age of study patients was 57.5±16.31 years and five patients were Standford type A and three patients were type B aortic dissection. Six patients had ST-segment elevation in anterior leads and two patients had in inferior leads. Most of the patients had acute onset, severe chest pain but no patients had dissecting nature chest pain. Serum troponin I was elevated in three patients but all patients had D-dimer elevation. Aortic regurgitation or regional wall motion abnormality was founded in four patients. However, widened mediastinum was seen in all study patients. Conclusion: When patients with STEMI have elevated D-dimer and widened mediastinum, concomitant AAS may have to be suspected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aortic%20dissection" title="aortic dissection">aortic dissection</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20infarction" title=" myocardial infarction"> myocardial infarction</a>, <a href="https://publications.waset.org/abstracts/search?q=ST-segment" title=" ST-segment"> ST-segment</a>, <a href="https://publications.waset.org/abstracts/search?q=d-dimer" title=" d-dimer"> d-dimer</a> </p> <a href="https://publications.waset.org/abstracts/37573/clinical-features-of-acute-aortic-dissection-patients-initially-diagnosed-with-st-segment-elevation-myocardial-infarction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37573.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Effect of Seasonal Variation on Two Introduced Columbiformes in Awba Dam Tourism Centre, University of Ibadan, Ibadan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kolawole%20F.%20Farinloye">Kolawole F.

Blood samples were obtained from superficial ulna vein of the 128 apparently healthy C. livia and C. guinea into tubes containing EDTA as anticoagulant. Thin blood smears (TBS) were prepared, stained and viewed under microscope. Values of Red Blood Cell (RBC) count, White Blood Cell (WBC) count, cholesterol (CH), Uric Acid (UA), Protein (PR), Mean Corpuscular Volume (MCV), Haemoglobin Content (HB), Blood Volume (BV), Plasma Glucose (PG) and Length/Width (L/W) ratio of red blood cells were assessed. The procedure was carried out on a seasonal basis (wet and dry seasons of 2013-2014). Data was analyzed using descriptive and inferential statistics. Lymphocyte count for C. livia was F3, 161 = 13.15, while for C. guinea was F3, 178 = 13.15. Heterophil, H/L ratio and Muscle score values for both species were (rs = -0.38, rs = -0.44), (rs = 0.51, rs = 0.31) (4, 3) respectively. Analyses also demonstrated a low WBC to RBC ratio (0.004: 25.3) in both species during the wet season compared to dry season, respectively. L/W varied significantly among sampling seasons i.e. wet (19.1% of BV, 12.6% of BV, 0.1% of BV) and dry (18.9% of BV, 12.7% of BV, 0.08% of BV). The level of HB in wet season (19.20±8.46108) is lower compared to dry season (19.70±8.48762). T-test also showed (wet=15.625, 0.111), (dry=12.125, 0.146) respectively, hence there is no association between species and haematological parameters. Species introduced were found to be haematologically stable. Although there were slight differences in seasonal composition, however this can be attributed to seasonal variation; suggesting little or no effect of seasons on their blood composition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seasonal%20variation" title="seasonal variation">seasonal variation</a>, <a href="https://publications.waset.org/abstracts/search?q=Columbiformes" title=" Columbiformes"> Columbiformes</a>, <a href="https://publications.waset.org/abstracts/search?q=Awba%20Dam%20tourism%20centre" title=" Awba Dam tourism centre"> Awba Dam tourism centre</a>, <a href="https://publications.waset.org/abstracts/search?q=University%20of%20Ibadan" title=" University of Ibadan"> University of Ibadan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibadan" title=" Ibadan"> Ibadan</a> </p> <a href="https://publications.waset.org/abstracts/71108/effect-of-seasonal-variation-on-two-introduced-columbiformes-in-awba-dam-tourism-centre-university-of-ibadan-ibadan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Preparation of Frozen Bivalent Babesial (Babesia Bovis and Babesia Bigemina) Vaccine from Field Isolates and Evaluation of Its Efficacy in Calves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Fiaz%20Qamar">Muhammad Fiaz Qamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Faraz"> Ahmad Faraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Arfan%20Zaman"> Muhammad Arfan Zaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazim%20Ali"> Kazim Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Akram"> Waleed Akram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Babesiosis is reflected as the most important disease of cattle that are transmitted by arthropods. In Pakistan, its prevalence is up to 29% in the cattle and buffalo population in different regions. Cattle show a long lasting and durable immunity by giving an infection of B.bovis, B. bigemina, or Babesiadivergens. this is used in cattle to immunize them in a few countries as anti-babesiosis vaccine. Development of frozen vaccine allows for complete testing after production of each batch, However, once thawed, its reduced its shelf life, frozen vaccines are more difficult to transport as well as expensive to produce as compared to chilled vaccine. The contamination of blood derived vaccine has the potential risk that makes pre-production and post-production quality control necessary. For the trail master seed production of whole blood frozen bivalent Babesia(Babesiabovis and Babesiabigemina), 100 blood samples of Babesial positive suspected cattle was taken and processed for separation microscopic detection and rectification by PCR. Vaccine passages were done to reduce the parasitaemiasis in live calves. After 8 passages, parasitemia of Babesia reduced from 80% to 15%. Infected donor calf’s blood was taken by jugular cannulation by using preservative free lithium heparin as an anticoagulant (5 International Units IU heparin/ml blood). In lab, parasite containing blood was mixed in equal volumes with 3 M glycerol in PBS supplemented with 5 mM glucose (final concentration of glycerol 1.5 M) at 37°C. The mixture was then equilibrized at 37°C for 30 minutes and were dispensed in required containers (e.g., 5 ml cryovials). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distribution" title="distribution">distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=babesia" title=" babesia"> babesia</a>, <a href="https://publications.waset.org/abstracts/search?q=primer%20sequences" title=" primer sequences"> primer sequences</a>, <a href="https://publications.waset.org/abstracts/search?q=PCV" title=" PCV"> PCV</a> </p> <a href="https://publications.waset.org/abstracts/152432/preparation-of-frozen-bivalent-babesial-babesia-bovis-and-babesia-bigemina-vaccine-from-field-isolates-and-evaluation-of-its-efficacy-in-calves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152432.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Greenlight Laser Prostatectomy: A Safe and Effective Day Case Option for Bladder Outlet Obstruction in the Elderly Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gordon%20Weight">Gordon Weight</a>, <a href="https://publications.waset.org/abstracts/search?q=Hermione%20Tsoi"> Hermione Tsoi</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Cutinha"> Patrick Cutinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Rajpal"> Sanjay Rajpal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Greenlight-laser prostatectomy (GLLP) is becoming a popular treatment option for bladder outlet obstruction and lower urinary tract symptoms (LUTS). In this retrospective study, we aim to explore the patient selection, perioperative morbidity, and functional outcomes of GLLP. Methods: Patients who underwent GLLP at a UK tertiary centre between June 2018 and November 2021 were included in this study. Retrospective data covering patient demographics, perioperative parameters and postoperative outcomes were collected using the electronic records systems. Results: 305 patients were included in this study with a mean age of 73 (range 30-90) years. The most common indication (62.6%) for the procedure was patient’s wish to be free from long-term catheters (LTC) or intermittent catheterisation (ISC), followed by failed medical therapy for LUTS (36.4%). 84.6% of patients had an ASA ≥2, and 32.1% took anticoagulant or antiplatelet therapy. Inpatient stays were minimal, with the majority (68.2%) of patients were performed as day case, and only 10.5% of patients requiring more than a single night admission. The 3-month readmission rate was 10.8%, with the most common causes being haematuria and urinary-tract infection. The successful TWOC rate at follow up was 91.2%. Amongst the 19 patients who failed TWOC, 14 had LTC prior to the procedure and 4 had been performing ISC. Conclusions: Our study shows that GLLP is a safe and effective day case treatment and can be suitable for elderly and comorbid patients. Patients requiring LTC or ISC pre-operatively should be counselled carefully about the risk of not being catheter-free post procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urology" title="urology">urology</a>, <a href="https://publications.waset.org/abstracts/search?q=endourology" title=" endourology"> endourology</a>, <a href="https://publications.waset.org/abstracts/search?q=prostate" title=" prostate"> prostate</a>, <a href="https://publications.waset.org/abstracts/search?q=bladder%20outlet%20obstruction" title=" bladder outlet obstruction"> bladder outlet obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=laser" title=" laser"> laser</a> </p> <a href="https://publications.waset.org/abstracts/164029/greenlight-laser-prostatectomy-a-safe-and-effective-day-case-option-for-bladder-outlet-obstruction-in-the-elderly-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164029.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> The Study of Platelet-Rich Plasma(PRP) on Wounds of OLEFT Rats Using Expression of MMP-2, MMP-9 mRNA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ho%20Seong%20Shin">Ho Seong Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: A research in relation to wound healing also showed that platelet-rich plasma (PRP) was effective on normal tissue regeneration. Nonetheless, there is no evidence that when platelet-rich plasma was applied on diabetic wound, it normalize diabetic wound healing process. In this study, we have analyzed matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) expression to know the effect of PRP on diabetic wounds using Reverse transcription-polymerase chain reaction (RT-PCR) of MMP-2, MMP-9 mRNA. Materials and Methods: Platelet-rich plasma (PRP) was prepared from blood of 6 rats. The whole 120-mL was added immediately to an anticoagulant. Citrate phosphonate dextrose(CPD) buffer (0.15 mg CPDmL) in a ratio of 1 mL of CPD buffer to 5 mL of blood. The blood was then centrifuged at 220g for 20minutes. The supernatant was saved to produce fibrin glue. The participate containing PRP was used for second centrifugation at 480g for 20 minutes. The pellet from the second centrifugation was saved and diluted with supernatant until the platelet concentration became 900,000/μL. Twenty male, 4week-old OLETF rats were underwent operation; each rat had two wounds created on left and right sides. The each wound of left side was treated with PRP gel, the wound of right side was treated with physiologic saline gauze. Results: RT-PCR analysis; The levels of MMP-2 mRNA in PRP applied tissues were positively related to postwounding days, whereas MMP-2 mRNA expression in saline-applied tissues remained in 5day after treatment. MMP-9 mRNA was undetectable in saline-applied tissues for either tissue, except 3day after treatment. Following PRP-applied tissues, MMP-9 mRNA expression was detected, with maximal expression being seen at third day. The levels of MMP-9 mRNA in PRP applied tissues were reported high intensity of optical density related to saline applied tissues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes" title="diabetes">diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=MMP-2" title=" MMP-2"> MMP-2</a>, <a href="https://publications.waset.org/abstracts/search?q=MMP-9" title=" MMP-9"> MMP-9</a>, <a href="https://publications.waset.org/abstracts/search?q=OLETF" title=" OLETF"> OLETF</a>, <a href="https://publications.waset.org/abstracts/search?q=PRP" title=" PRP"> PRP</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20healing%0D%0AMMP-9" title=" wound healing MMP-9"> wound healing MMP-9</a> </p> <a href="https://publications.waset.org/abstracts/39065/the-study-of-platelet-rich-plasmaprp-on-wounds-of-oleft-rats-using-expression-of-mmp-2-mmp-9-mrna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39065.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">273</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Pulmonary Embolism Indicative of Myxoma of the Right Atrium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Kherraf">A.

The purpose of this observation is to report a rare case of myxoma of the right atrium revealed by pulmonary embolism. Observation: A 34-year-old patient with no history presented to the emergency room with sudden onset dyspnea. Clinical examination showed arterial pressure at 110/70mmHg, tachycardia at 110bpm, and 90% oxygen saturation. The ECG enrolled in incomplete right bundle branch block. The radio-thorax was normal. Echocardiography revealed the presence of a large homogeneous intra-OD mass, contiguous to the inter-atrial septum, prolapsing through the tricuspid valve, and causing mild tricuspid insufficiency, with dilation of the right ventricle and retained systolic function with PAPs estimated at 45mmHg. A chest scan was performed, revealing the presence of right segmental pulmonary embolism. The patient was put under anticoagulant and underwent surgical resection of the mass; its pathological examination concluded to a myxoma. The post-operative consequences were simple, without recurrence of the mass after one year follow-up. Discussion: Myxomas represent 50% of heart tumors. Most often, they originate in the left atrium, and more rarely in the right atrium or the ventricles. Myxoma of the right atrium can be responsible for life-threatening pulmonary embolism. The most predictive factor for embolization remains the morphology of the myxomas; papillary or villous myxomas are the most friable. Surgery is the standard treatment, with regular postoperative follow-up to detect recurrence. Conclusion: Myxomas of the right atrium are a rare location for these tumors. Pulmonary embolism is the main complication and should routinely involve careful study of the right chambers on echocardiography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20embolism" title="pulmonary embolism">pulmonary embolism</a>, <a href="https://publications.waset.org/abstracts/search?q=myxoma" title=" myxoma"> myxoma</a>, <a href="https://publications.waset.org/abstracts/search?q=right%20atrium" title=" right atrium"> right atrium</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20tumors" title=" heart tumors "> heart tumors </a> </p> <a href="https://publications.waset.org/abstracts/130820/pulmonary-embolism-indicative-of-myxoma-of-the-right-atrium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130820.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Prasugrel as First-line Therapy for Stemi Patients Undergoing PPCI</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diab%20Z.">Diab Z.</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamad%20A."> Hamad A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Dixit%20A."> Dixit A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Al-Rikabi%20M."> Al-Rikabi M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Keshaverzi%20F."> Keshaverzi F.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: According to the NICE guidelines, 2020Prasugrel is the recommended first line treatment in adults with acute coronary syndromes (ACS) in patients with ST-segment-elevation myocardial infarction (STEMI), defined as ST elevation or new left bundle branch block on ECG , that cardiologists intend to treat with primary percutaneous coronary intervention (PCI). The current literature suggests that this is largely due to safety and efficacy, and cost effectiveness.

AIM: To examine the adherence of the MRI hospital with guidelines in using prasugrel as first-line therapy in patients with STEMI and undergoing PPCI Methods: We looked at the patients presented to MRI during1^st of January 2022 to 28th February 2022. We included all the people who were above 18 and were brought to the hospital through the PPCI pathway and diagnosed as ACS and underwent PPCI. We excluded Patients who were brought to the hospital through the PPCI pathway and underwent coronary angiography and their diagnosis was found other than STEMI or if the outcome was death before discharge or they were above age >75 (as per guideline increase bleeding risk of prasugrel in a person aged 75 or older). Results: The total number of patients was 100. There were a total of seventy patients who had STEMI and fit the criteria for inclusion. Out of these, only 72.9% (51) were given Prasugrel as a first line. Seventeen (17) 24.3% STEMI patients were candidates for prasugrel as first-line therapy but were instead offered (clopidogrel/ticagrelor). Two 2 (2.9%) STEMI patients were not given prasugrel as first-line therapy because of C/I (CVA) or the use of anticoagulant Nine 9 (9%) of them died before discharge. Eleven 11 (11%) were above the age of 75. Ten 10 (10%) of patients had a diagnosis other than STEMI. Conclusions and recommendations: Our audit has shown the need to increase awareness amongst staff re: the first line use of Prasugrel as per NICE guidelines. We aim to arrange awareness sessions for staff and increase visibility of the guidelines for the staff to encourage them to adhere to the guideline. Further research is needed to find the optimum treatment in patients above 75. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pasurgrel" title="pasurgrel">pasurgrel</a>, <a href="https://publications.waset.org/abstracts/search?q=PCI" title=" PCI"> PCI</a>, <a href="https://publications.waset.org/abstracts/search?q=NICE" title=" NICE"> NICE</a>, <a href="https://publications.waset.org/abstracts/search?q=STEMI" title=" STEMI"> STEMI</a> </p> <a href="https://publications.waset.org/abstracts/156523/prasugrel-as-first-line-therapy-for-stemi-patients-undergoing-ppci" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Synthetic Coumarin Derivatives and Their Anticancer Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kabange%20Kasumbwe">Kabange Kasumbwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Viresh%20Mohanlall"> Viresh Mohanlall</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharti%20Odhav"> Bharti Odhav</a>, <a href="https://publications.waset.org/abstracts/search?q=Venu%20Narayanaswamy"> Venu Narayanaswamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coumarins are naturally occurring plant metabolites known for their pharmacological properties such as anticoagulant, antimicrobial, anticancer, antioxidant, anti-inflammatory and antiviral properties. The pharmacological and biochemical properties and curative applications of coumarins depend on the substitution around the coumarin core structure. In the present study, seven halogenated coumarins CMRN1-CMRN7 were synthesized and evaluated for their anticancer activity. The cytotoxicity potential of the test compounds was evaluated against UACC62 (Melanoma), MCF-7 (Breast cancer) and PBM (Peripheral Blood Mononuclear) cell lines using MTT assay keeping doxorubicin as standard drug. The apoptotic potential of the coumarin compounds was evaluated against UACC62 (Melanoma) cell by assessing their morphological changes, membrane change, mitochondria membrane potential; pro-apoptotic changes were investigated using the AnnexinV-PI staining, JC-1, caspase-3 enzyme kits respectively on flow cytometer. The synthetic coumarin has strongly suppressed the cell proliferation of UACC-62 (Melanoma) and MCF-7 (Breast) Cancer cells, the higher toxicity of these compounds against UACC-62 (Melanoma) and MCF-7 (Breast) were CMRN3, CMRN4, CMRN5, CMRN6. However, compounds CMRN1, CMRN2, and CMRN7 had no significant inhibitory effect. Furthermore the active compounds CMRN3, CMRN4, CMRN5, CMRN6 exerted antiproliferative effects through apoptosis induction against UACC-62 (Melanoma), suggesting their potential could be considered as attractive lead molecules in the future for the development of potential anticancer agents since one of the important criteria in the development of therapeutic drugs for cancer treatment is to have high selectivity and less or no side-effects on normal cells and these compounds had no inhibitory effect against the PBMC cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coumarin" title="coumarin">coumarin</a>, <a href="https://publications.waset.org/abstracts/search?q=MTT" title=" MTT"> MTT</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title=" cytotoxicity"> cytotoxicity</a> </p> <a href="https://publications.waset.org/abstracts/59987/synthetic-coumarin-derivatives-and-their-anticancer-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59987.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Rodents Control in Poultry Production; Harnessing Conflicting Animal Welfare Interests in Developing Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20M.%20Alabi">O.

Rats and mice are rodents commonly found in poultry houses in most of the African countries. More than 20,000 species of rat have been identified in Africa among which are; Black house rats (Rattus rattus), East African mole rat (Tachyorcytes splendens), Naked mole rat (Heterocephalus glaber), Zambian mole rat (Fukomys mechowii), African grass rat (Arvicanthis niloticus), Nigerian mole rat (Cryptomys foxi), Target rat (Stochomys longicaudatus) and West African Shaggy rat (Dasymis rufulus). Apart from being destructive, rats and mice are voracious in that they compete with chickens for feed and water thereby causing economical losses to the farmer, they are also vectors to many pathogens of poultry diseases such as Salmonellosis, colibacillosis, ascaridiasis, coryza, pasteurellosis and mycoplasmosis. As bad as these rodents are to the poultry farmers, they are good sources of animal protein to local hunters and other farmers in most African countries. Rat is considered a delicacy in Nigeria and many other African countries hence the need to investigate into how the rats species will not go into extinction. Rodents are usually controlled by poultry farmers with the use of rodenticides which can either be anticoagulant or stomach poison, and with the use of baits. However, elimination of rats and mice is being considered as callous act against these species of animal and their natural existence as human food also. This paper therefore suggests that sanitation methods such as feed removal from rats and mice, controlling feed and water spillage, proper disposal of waste eggs, dead birds and garbage, keeping the surroundings of the poultry clean; rodent proofing by making it difficult for rodents to enter the poultry houses are some of the humane ways of controlling rodents in poultry production to avoid improving the welfare of a particular animal at the expense of the other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=management" title="management">management</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry" title=" poultry"> poultry</a>, <a href="https://publications.waset.org/abstracts/search?q=rodents" title=" rodents"> rodents</a>, <a href="https://publications.waset.org/abstracts/search?q=welfare" title=" welfare"> welfare</a> </p> <a href="https://publications.waset.org/abstracts/45903/rodents-control-in-poultry-production-harnessing-conflicting-animal-welfare-interests-in-developing-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45903.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">419</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> A Review of Toxic and Non-Toxic Cyanobacteria Species Occurrence in Water Supplies Destined for Maize Meal Production Process: A Case Study of Vhembe District</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Mutoti">M.

Jideani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cyanobacteria or blue green algae have been part of the human diet for thousands of years. Cyanobacteria can multiply quickly in surface waters and form blooms when favorable conditions prevail, such as high temperature, intense light, high pH, and increased availability of nutrients, especially phosphorous and nitrogen, artificially released by anthropogenic activities. Consumption of edible cyanotoxins such as Spirulina may reduce risks of cataracts and age related macular degeneration. Sulfate polysaccharides exhibit antitumor, anticoagulant, anti-mutagenic, anti-inflammatory, antimicrobial, and even antiviral activity against HIV, herpes, and hepatitis. In humans, exposure to cyanotoxins can occur in various ways; however, the oral route is the most important. This is mainly through drinking water, or by eating contaminated foods; it may even involve ingesting water during recreational activities. This paper seeks to present a review on cyanobacteria/cyanotoxin contamination of water and food and implications for human health. In particular, examining the water quality used during maize seed that passes through mill grinding processes. In order to fulfil the objective, this paper starts with the theoretical framework on cyanobacteria contamination of food that will guide review of the present paper. A number of methods for decontaminating cyanotoxins in food is currently available. Therefore, physical, chemical, and biological methods for treating cyanotoxins are reviewed and compared. Furthermore, methods that are utilized for detecting and identifying cyanobacteria present in water and food were also informed in this review. This review has indicated various routes through which humans can be exposed to cyanotoxins. Accumulation of cyanotoxins, mainly microcystins, in food has raised an awareness of the importance of food as microcystins exposure route to human body. Therefore, this review demonstrates the importance of expanding research on cyanobacteria/cyanotoxin contamination of water and food for water treatment and water supply management, with focus on examining water for domestic use. This will help providing information regarding the prevention or minimization of contamination of water and food, and also reduction or removal of contamination through treatment processes and prevention of recontamination in the distribution system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofilm" title="biofilm">biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=cyanobacteria" title=" cyanobacteria"> cyanobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=cyanotoxin" title=" cyanotoxin"> cyanotoxin</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20contamination" title=" food contamination"> food contamination</a> </p> <a href="https://publications.waset.org/abstracts/103448/a-review-of-toxic-and-non-toxic-cyanobacteria-species-occurrence-in-water-supplies-destined-for-maize-meal-production-process-a-case-study-of-vhembe-district" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103448.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Effective Apixaban Clearance with Cytosorb Extracorporeal Hemoadsorption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Klazina%20T.%20Havinga">Klazina T.

Apixaban is not dialyzable due to its high level of protein binding. An antidote, Andexanet α, is available but expensive and has an unfavorable short half-life. We report the successful extracorporeal removal of Apixaban prior to emergency surgery with the CytoSorb® Hemoadsorption device. Methods: A 89-year-old woman with CKD, with an Apixaban prescription for atrial fibrillation, was presented at the ER with traumatic rib fractures, a flail chest, and an unstable spinal fracture (T12) for which emergency surgery was indicated. However, due to very high Apixaban levels, this surgery had to be postponed. Based on the Apixaban-specific anti-factor Xa activity (AFXaA) measurements at admission and 10 hours later, complete clearance was expected after 48 hours. In order to enhance the Apixaban removal and reduce the time to operation, and therefore reduce pulmonary complications, CRRT with CytoSorb® cartridge was initiated. Apixaban-specific anti-factor Xa activity (AFXaA) was measured frequently as a substitute for Apixaban drug concentrations, pre- and post adsorber, in order to calculate the adsorber-related clearance. Results: The admission AFXaA concentration, as a substitute for Apixaban drug levels, was 218 ng/ml, which decreased to 157 ng/ml after ten hours. Due to sustained anticoagulation effects, surgery was again postponed. However, the AFXaA levels decreased quickly to sub-therapeutic levels after CRRT (Multifiltrate Pro, Fresenius Medical Care, Blood flow 200 ml/min, Dialysate Flow 4000 ml/h, Prescribed renal dose 51 ml-kg-h) with Cytosorb® connected in series into the circuit was initiated (within 5 hours). The adsorber-related (indirect) Apixaban clearance was calculated every half hour (Cl=Qe * (AFXaA pre- AFXaA post/ AFXaA pre) with Qe=plasma flow rate calculated with Ht=0.38 and system blood flow rate 200 ml-min): 100 ml/min, 72 ml/min and 57 ml/min. Although, as expected, the adsorber-related clearance decreased quickly due to saturation of the beads, still the reduction rate achieved resulted in a very rapid decrease in AFXaA levels. Surgery was ordered and possible within 5 hours after Cytosorb initiation. Conclusion: The CytoSorb® Hemoadsorption device enabled rapid correction of Apixaban associated anticoagulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Apixaban" title="Apixaban">Apixaban</a>, <a href="https://publications.waset.org/abstracts/search?q=CytoSorb" title=" CytoSorb"> CytoSorb</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20surgery" title=" emergency surgery"> emergency surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=Hemoadsorption" title=" Hemoadsorption"> Hemoadsorption</a> </p> <a href="https://publications.waset.org/abstracts/152958/effective-apixaban-clearance-with-cytosorb-extracorporeal-hemoadsorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152958.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Selection of Suitable Reference Genes for Assessing Endurance Related Traits in a Native Pony Breed of Zanskar at High Altitude</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prince%20Vivek">Prince Vivek</a>, <a href="https://publications.waset.org/abstracts/search?q=Vijay%20K.%20Bharti"> Vijay K.

We hypothesized that the identification of the suitable reference genes might be considered for assessing of endurance related traits in pony at high altitude and may ensure for individuals struggling to potent endurance trait in ponies at high altitude. A total of 12 mares of ponies, Zanskar breed, were divided into three groups, group-A (without load), group-B, (60 Kg) and group-C (80 Kg) on backpack loads were subjected to a load carry protocol, on a steep climb of 4 km uphill, and of gravel, uneven rocky surface track at an altitude of 3292 m to 3500 m (endpoint). Blood was collected before and immediately after the load carry on sodium heparin anticoagulant, and the peripheral blood mononuclear cell was separated for total RNA isolation and thereafter cDNA synthesis. Real time-PCR reactions were carried out to evaluate the mRNAs expression profile of a panel of putative internal control genes (ICGs), related to different functional classes, namely glyceraldehyde 3-phosphate dehydrogenase (GAPDH), β₂ microglobulin (β₂M), β-actin (ACTB), ribosomal protein 18 (RS18), hypoxanthine-guanine phosophoribosyltransferase (HPRT), ubiquitin B (UBB), ribosomal protein L32 (RPL32), transferrin receptor protein (TFRC), succinate dehydrogenase complex subunit A (SDHA) for normalizing the real-time quantitative polymerase chain reaction (qPCR) data of native pony’s. Three different algorithms, geNorm, NormFinder, and BestKeeper software, were used to evaluate the stability of reference genes. The result showed that GAPDH was best stable gene and stability value for the best combination of two genes was observed TFRC and β₂M. In conclusion, the geometric mean of GAPDH, TFRC and β₂M might be used for accurate normalization of transcriptional data for assessing endurance related traits in Zanskar ponies during load carrying. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endurance%20exercise" title="endurance exercise">endurance exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=ubiquitin%20B%20%28UBB%29" title=" ubiquitin B (UBB)"> ubiquitin B (UBB)</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B2%E2%82%82%20microglobulin%20%28%CE%B2%E2%82%82M%29" title=" β₂ microglobulin (β₂M)"> β₂ microglobulin (β₂M)</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20altitude" title=" high altitude"> high altitude</a>, <a href="https://publications.waset.org/abstracts/search?q=Zanskar%20ponies" title=" Zanskar ponies"> Zanskar ponies</a>, <a href="https://publications.waset.org/abstracts/search?q=reference%20gene" title=" reference gene"> reference gene</a> </p> <a href="https://publications.waset.org/abstracts/94149/selection-of-suitable-reference-genes-for-assessing-endurance-related-traits-in-a-native-pony-breed-of-zanskar-at-high-altitude" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94149.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Use of a Novel Intermittent Compression Shoe in Reducing Lower Limb Venous Stasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hansraj%20Riteesh%20Bookun">Hansraj Riteesh Bookun</a>, <a href="https://publications.waset.org/abstracts/search?q=Cassandra%20Monique%20Hidajat"> Cassandra Monique Hidajat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This pilot study investigated the efficacy of a newly designed shoe which will act as an intermittent pneumatic compression device to augment venous flow in the lower limb. The aim was to assess the degree with which a wearable intermittent compression device can increase the venous flow in the popliteal vein. Background: Deep venous thrombosis and chronic venous insufficiency are relatively common problems with significant morbidity and mortality. While mechanical and chemical thromboprophylaxis measures are in place in hospital environments (in the form of TED stockings, intermittent pneumatic compression devices, analgesia, antiplatelet and anticoagulant agents), there are limited options in a community setting. Additionally, many individuals are poorly tolerant of graduated compression stockings due to the difficulty in putting them on, their constant tightness and increased associated discomfort in warm weather. These factors may hinder the management of their chronic venous insufficiency. Method: The device is lightweight, easy to wear and comfortable, with a self-contained power source. It features a Bluetooth transmitter and can be controlled with a smartphone. It is externally almost indistinguishable from a normal shoe. During activation, two bladders are inflated -one overlying the metatarsal heads and the second at the pedal arch. The resulting cyclical increase in pressure squeezes blood into the deep venous system. This will decrease periods of stasis and potentially reduce the risk of deep venous thrombosis. The shoe was fitted to 2 healthy participants and the peak systolic velocity of flow in the popliteal vein was measured during and prior to intermittent compression phases. Assessments of total flow volume were also performed. All haemodynamic assessments were performed with ultrasound by a licensed sonographer. Results: Mean peak systolic velocity of 3.5 cm/s with standard deviation of 1.3 cm/s were obtained. There was a three fold increase in mean peak systolic velocity and five fold increase in total flow volume. Conclusion: The device augments venous flow in the leg significantly. This may contribute to lowered thromboembolic risk during periods of prolonged travel or immobility. This device may also serve as an adjunct in the treatment of chronic venous insufficiency. The study will be replicated on a larger scale in a multi—centre trial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=venous" title="venous">venous</a>, <a href="https://publications.waset.org/abstracts/search?q=intermittent%20compression" title=" intermittent compression"> intermittent compression</a>, <a href="https://publications.waset.org/abstracts/search?q=shoe" title=" shoe"> shoe</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20device" title=" wearable device"> wearable device</a> </p> <a href="https://publications.waset.org/abstracts/77649/use-of-a-novel-intermittent-compression-shoe-in-reducing-lower-limb-venous-stasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77649.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Retrospective Analysis of 142 Cases of Incision Infection Complicated with Sternal Osteomyelitis after Cardiac Surgery Treated by Activated PRP Gel Filling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daifeng%20Hao">Daifeng Hao</a>, <a href="https://publications.waset.org/abstracts/search?q=Guang%20Feng"> Guang Feng</a>, <a href="https://publications.waset.org/abstracts/search?q=Jingfeng%20Zhao"> Jingfeng Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Li"> Tao Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoye%20Tuo"> Xiaoye Tuo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To retrospectively analyze the clinical characteristics of incision infection with sternal osteomyelitis sinus tract after cardiac surgery and the operation method and therapeutic effect of filling and repairing with activated PRP gel. Methods: From March 2011 to October 2022, 142 cases of incision infection after cardiac surgery with sternal osteomyelitis sinus were retrospectively analyzed, and the causes of poor wound healing after surgery, wound characteristics, perioperative wound management were summarized. Treatment during operation, collection and storage process of autologous PRP before debridement surgery, PRP filling repair and activation method after debridement surgery, effect of anticoagulant drugs on surgery, postoperative complications and average wound healing time, etc.. Results: Among the cases in this group, 53.3% underwent coronary artery bypass grafting, 36.8% underwent artificial heart valve replacement, 8.2% underwent aortic artificial vessel replacement, and 1.7% underwent allogeneic heart transplantation. The main causes of poor incision healing were suture reaction, fat liquefaction, osteoporosis, diabetes, and metal allergy in sequence. The wound is characterized by an infected sinus tract. Before the operation, 100-150ml of PRP with 4 times the physiological concentration was collected separately with a blood component separation device. After sinus debridement, PRP was perfused to fill the bony defect in the middle of the sternum, activated with thrombin freeze-dried powder and calcium gluconate injection to form a gel, and the outer skin and subcutaneous tissue were sutured freely. 62.9% of patients discontinued warfarin during the perioperative period, and 37.1% of patients maintained warfarin treatment. There was no significant difference in the incidence of postoperative wound hematoma. The average postoperative wound healing time was 12.9±4.7 days, and there was no obvious postoperative complication. Conclusions: Application of activated PRP gel to fill incision infection with sternal osteomyelitis sinus after cardiac surgery has a less surgical injury and satisfactory and stable curative effect. It can completely replace the previously used pectoralis major muscle flap transplantation operation scheme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=platelet-rich%20plasma" title="platelet-rich plasma">platelet-rich plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=negative-pressure%20wound%20therapy" title=" negative-pressure wound therapy"> negative-pressure wound therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=sternal%20osteomyelitis" title=" sternal osteomyelitis"> sternal osteomyelitis</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20surgery" title=" cardiac surgery"> cardiac surgery</a> </p> <a href="https://publications.waset.org/abstracts/159811/retrospective-analysis-of-142-cases-of-incision-infection-complicated-with-sternal-osteomyelitis-after-cardiac-surgery-treated-by-activated-prp-gel-filling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159811.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Aspergillus micromycetes as Producers of Hemostatically Active Proteases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexander%20A.%20Osmolovskiy">Alexander A.

At the same time, practical medicine needs specific activators for quantitation of the level of some plasma enzymes, especially protein C and factor X, the lack of which leads to the development of thromboembolic diseases. Thus, some micromycetes of the genus Aspergillus were screened for the ability to synthesize extracellular proteases with promising activity for designing anti-thrombotic and diagnostic preparations. Such standard methods like salting out, electrophoresis, isoelectrofocusing were used for isolation, purification and study of physicochemical properties of proteases. Enzyme activity was measured spectrophotometrically fibrin as a substrate of the reaction and chromogenic peptide substrates of different proteases of the human hemostasis system. As a result of the screening, four active producers were selected: Aspergillus janus 301, A. flavus 1, A. terreus 2, and A. ochraceus L-1. The enzyme of A. janus 301 showed the greatest fibrinolytic activity (around 329.2 μmol Tyr/(ml × min)). The protease produced by A. terreus 2 had the highest plasmin-like activity (54.1 nmol pNA/(ml × min)), but fibrinolytic activity was lower than A. janus 301 demonstrated (25.2 μmol Tyr/(ml × min)). For extracellular protease of micromycete A. flavus a high plasmin-like activity was also shown (39.8 nmol pNA / (ml × min)). Moreover, according to our results proteases one of the fungi - A. terreus 2 were able to activate protein C of human plasma - the key factor of the human anticoagulant hemostasis system. This type of activity was 39.8 nmol pNA/(ml × min)). It was also shown that A. ochraceus L-1 could produce extracellular proteases with protein C and factor X activator activities (65.9 nmol pNA/(ml × min) and 34.6 nmol pNA/(ml × min) respectively). The maximum accumulation of the proteases falls on the 4th day of cultivation. Using isoelectrofocusing was demonstrated that the activation of both proenzymes might proceed via limited proteolysis induced by proteases of A. ochraceus L-1. The activatory activity of A. ochraceus L-1 proteases toward essential hemostatic proenzymes, protein C and X factor may be useful for practical needs. It is well known that similar enzymes, activators of protein C and X factor isolated from snake venom, South American copperhead Agkistrodon contortrix contortrix and Russell’s viper Daboia russelli russeli, respectively, are used for the in vitro diagnostics of the functional state of these proteins in blood plasma. Thus, the proteases of Aspergillus genus can be used as cheap components for enzyme thrombolytic preparations. <p class="card-text"><strong>Keywords:</strong> <a
