The sensitivity of this test is close to 90 % making it a very reliable test. However, rarely it gives a false negative result which can be explained by the phenomenon termed as “balanced ischaemia”. We present the case of a 78 year Caucasian female without any significant past cardiac history, who presents with chest pain and shortness of breath since one day. The initial ECG and cardiac enzymes were non-impressive. Few hours later, she had some substernal chest pain along with some ST segment depression in the lateral leads. Stress test comes back negative for any significant perfusion defects. However, given her typical symptoms, she underwent a cardiac catheterization which revealed significant triple vessel disease mandating her to get a bypass surgery. This unusual phenomenon of false nuclear stress test in the setting of positive ECG changes can be explained only by balanced ischemia wherein due to global myocardial ischemia, the stress test fails to reveal relative perfusion defects in the affected segments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balanced" title="balanced">balanced</a>, <a href="https://publications.waset.org/abstracts/search?q=false%20positive" title=" false positive"> false positive</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia" title=" ischemia"> ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20perfusion%20imaging" title=" myocardial perfusion imaging"> myocardial perfusion imaging</a> </p> <a href="https://publications.waset.org/abstracts/49756/balanced-ischemia-misleading-to-a-false-negative-myocardial-perfusion-imaging-stress-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49756.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">299</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">533</span> Characterization of Coronary Artery Obstruction and Related Findings in Ischemic Heart Patients Using Cardiac Scintigraphy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousif%20Mohamed%20Y.%20Abdallah">Yousif Mohamed Y.

Olive oil is rich in monounsaturated fatty acids, and has been reported for variety of beneficial cardiovascular effects including blood pressure lowering, anti-platelet, anti-diabetic and anti-inflammatory effects. Growing number evidences from preclinical and clinical studies have shown that olive oil improves insulin resistance, decrease vessels stiffness and prevent thromboembolism. We evaluated the effects of olive against streptozotocin-induced physiological disorders in the animal models of diabetes and ischemia and reperfusion (I/R)- induced cardiac arrhythmias. Diabetes was induced in male rats with a single intraperitoneal injection of streptozotocin (60 mg/kg), rats were treated for two months with olive oil (1 ml/kg p.o). Control animals received saline. Blood glucose, body weight were monitored every 14 days. At the end of the treatment rats were sacrificed hearts were isolated for mounting on langedorff’s apparatus. The blood glucose and body weight was not significantly different in the control and olive treated animals. The control diabetic animals exhibited 100% incidence of I/R –induced ventricular fibrillation which was reduced to 0% with olive oil, treatment. The duration of ventricular fibrillation reduced from 98.8± 2.3 (control) to 0 seconds in the olive oil treated group. Diltiazem, a calcium channel blocker (1 µm/L) showed similar results and protected the I/R-induced cardiac disorders. The biochemical analysis of the cardiac tissues showed that diabetes and I/R produce marked pathological changes in the cardiomyocytes including decreased glutathione (GSH) and increased oxidative stress (Malondialdehyde; MDA). Pretreatment of animals with olive oil (1 ml/kg p.o) increased GSH and MDA levels. Olive oil also improved the diabetic-induced histopathological changes in the cardiomyocytes. These finding indicates that olive possesses cardiac protective properties. Further studies are under way in our lab to explore the mechanism of the cardio-protective effect of olive oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabeties" title="diabeties">diabeties</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia-reperfusion" title=" ischemia-reperfusion"> ischemia-reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20oil" title=" olive oil"> olive oil</a>, <a href="https://publications.waset.org/abstracts/search?q=rats%20heart" title=" rats heart"> rats heart</a> </p> <a href="https://publications.waset.org/abstracts/33792/cardiac-protective-effect-of-olive-oil-against-ischemia-reperfusion-induced-cardiac-arrhythmias-in-isolated-diabetic-rat-hearts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33792.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">464</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">531</span> The Effect of β-Cryptoxanthin on Testicular Ischemia-Reperfusion Injury in a Rat Model: Evidence from Testicular Histology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kianoush%20Mohammadnejad">Kianoush Mohammadnejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahim%20Mohammadi"> Rahim Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Soleimanzadeh"> Ali Soleimanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Shalizar%20Jalai"> Ali Shalizar Jalai</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Sareafzadeh%20Rezaei"> Farshid Sareafzadeh Rezaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Testicular torsion and detorsion are significant clinical issues for infertile men. Torsion of the spermatic cord is an emergency condition resulting from the rotation of the testis and epididymis around the axis of the spermatic cord. A rat testis model was used to assess the effects of β-cryptoxanthin on ischemia-reperfusion injury. Twenty healthy male Wistar rats were included and randomized into four investigational groups (n = 5): Group SHAM: In this group, midline incision of the scrotum was performed, and the testicles were taken out for 2 hours with a 720-degree rotation. Group ISCHEMIA: In this group, a midline incision of the scrotum was performed, and the testicles were taken out and underwent ischemia for 2 hours with a 720-degree rotation. Group IS/REP/Oil: In this group, a midline scrotum cut was performed the testicles were taken out, and ischemia was created for 2 hours with a 720-degree rotation and at the end of ischemia 100 µL of corn oil (β-cryptoxanthin solvent) was injected intraperitoneally. Group IS/REP/CRPTXNTN 2.5: The same as group IS/REP/Oil as well as intraperitoneal administration of 100 µL of β-cryptoxanthin (2.5 µg/kg) at the end of ischemia. In all groups, the testes were returned back to the scrotum and, after 60 days, were dissected out and removed for histopathological analyses. β-cryptoxanthin at the dose of 2.5 µg/kg significantly improved histologic indices compared to other treatment groups (p<0.05). β-cryptoxanthin could be helpful in minimizing ischemia-reperfusion injury in testicular tissue exposed to ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-cryptoxanthin" title="beta-cryptoxanthin">beta-cryptoxanthin</a>, <a href="https://publications.waset.org/abstracts/search?q=testis" title=" testis"> testis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ischemia-reperfusion" title=" Ischemia-reperfusion"> Ischemia-reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Intraperitoneal" title=" Intraperitoneal"> Intraperitoneal</a> </p> <a href="https://publications.waset.org/abstracts/189306/the-effect-of-v-cryptoxanthin-on-testicular-ischemia-reperfusion-injury-in-a-rat-model-evidence-from-testicular-histology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189306.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">18</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">530</span> The Impact of Co-Administration of Phosphodiesterase-5 Inhibitor and Sodium Selenite on Ischemia/Reperfusion Injury in a Rat Ovary Model: Biochemical and Histopathologic Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Aly%20Sayed%20Ahmed">Waleed Aly Sayed Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Kishk"> Eman Kishk</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahani%20%20Shams"> Tahani Shams</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: To study the effects of co-administration of phosphodiesterase-5 inhibitor (PDE-5) and sodium selenite against the damage induced by ovarian ischemia-reperfusion in rats. Materials and Methods: A total of forty-two sexually mature, virgin, female rats were divided randomly into six groups of seven each: sham group (C), ischemia group (I), ischemia/reperfusion group (I/R), ischemia/reperfusion plus 1.4mg/kg sildenafil (I/R+S) group, ischemia/reperfusion plus 0.2mg/kg selenium (I/R+Se) group and ischemia/reperfusion plus combination of sildenafil and selenium (I/R+S+Se) group. In ischemia group (I), rats were exposed to ischemia for 3 hours (h). In ischemia/reperfusion group (I/R), rats were exposed to ischemia for 3 h followed by 6 h of reperfusion. Treated groups received 1.4mg/kg sildenafil or 0.2 mg/kg selenium or both 30 min before reperfusion. Both ovaries were surgically removed carefully. One ovary was examined for histopathological changes and the other was subject to biochemical analysis including malondialdehyde (MDA), catalase (CAT) and glutathione peroxidase (GPx). Results: Assessment of ovarian tissue damage using a scoring system showed marked vascular congestion, interstitial edema, leukocyte infiltration, hemorrhage, and follicular degeneration in ischemia and ischemia/reperfusion groups. Tissue damage score for I, IR and all treated groups were significantly higher than those of the sham group (p<0.001), while tissue damage score decreased significantly in I/R+S and I/R+Se groups compared to I/R group (p<0.05), and notably, the difference was highly significant in I/R+S+Se group (p<0.001). There was significant increase in MDA levels and reduction in activities of CAT and GPx in I/R group compared to the sham group (p < 0.05). In I/R+S and I/R+Se groups, MDA was significantly decreased compared to the I/R group (p<0.05) and the difference was highly significant with co-administration of sildenafil and selenium (p<0.001). CAT and GPx were higher in all treated groups compared to I/R group (p<0.05). Conclusion: The co-administration of sildenafil citrate and selenium are highly protective against damage induced by ovarian ischemia/reperfusion in rats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phosphodiesterase-5%20inhibitor" title="phosphodiesterase-5 inhibitor">phosphodiesterase-5 inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=sildenafil" title=" sildenafil"> sildenafil</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=selenium" title=" selenium"> selenium</a>, <a href="https://publications.waset.org/abstracts/search?q=ovarian%20ischemia" title=" ovarian ischemia"> ovarian ischemia</a> </p> <a href="https://publications.waset.org/abstracts/64362/the-impact-of-co-administration-of-phosphodiesterase-5-inhibitor-and-sodium-selenite-on-ischemiareperfusion-injury-in-a-rat-ovary-model-biochemical-and-histopathologic-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64362.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">312</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">529</span> Dynamic Cardiac Mitochondrial Proteome Alterations after Ischemic Preconditioning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelbary%20Prince">Abdelbary Prince</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Moussa"> Said Moussa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyungkyu%20Kim"> Hyungkyu Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Gouda"> Eman Gouda</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Han"> Jin Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We compared the dynamic alterations of mitochondrial proteome of control, ischemia-reperfusion (IR) and ischemic preconditioned (IPC) rabbit hearts. Using 2-DE, we identified 29 mitochondrial proteins that were differentially expressed in the IR heart compared with the control and IPC hearts. For two of the spots, the expression patterns were confirmed by Western blotting analysis. These proteins included succinate dehydrogenase complex, Acyl-CoA dehydrogenase, carnitine acetyltransferase, dihydrolipoamide dehydrogenase, Atpase, ATP synthase, dihydrolipoamide succinyltransferase, ubiquinol-cytochrome c reductase, translation elongation factor, acyl-CoA dehydrogenase, actin alpha, succinyl-CoA Ligase, dihydrolipoamide S-succinyltransferase, citrate synthase, acetyl-Coenzyme A dehydrogenase, creatine kinase, isocitrate dehydrogenase, pyruvate dehydrogenase, prohibitin, NADH dehydrogenase (ubiquinone) Fe-S protein, enoyl Coenzyme A hydratase, superoxide dismutase [Mn], and 24-kDa subunit of complex I. Interestingly, most of these proteins are associated with the mitochondrial respiratory chain, antioxidant enzyme system, and energy metabolism. The results provide clues as to the cardioprotective mechanism of ischemic preconditioning at the protein level and may serve as potential biomarkers for detection of ischemia-induced cardiac injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ischemic%20preconditioning" title="ischemic preconditioning">ischemic preconditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondria" title=" mitochondria"> mitochondria</a>, <a href="https://publications.waset.org/abstracts/search?q=proteome" title=" proteome"> proteome</a>, <a href="https://publications.waset.org/abstracts/search?q=cardioprotection" title=" cardioprotection"> cardioprotection</a> </p> <a href="https://publications.waset.org/abstracts/19291/dynamic-cardiac-mitochondrial-proteome-alterations-after-ischemic-preconditioning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19291.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">349</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">528</span> Grape Seed Extract and Zinc Containing Multivitamin-Mineral Nutritional Food Supplement Protects Heart against Myocardial Ischemic-Reperfusion Injury in Wistar Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20M.%20Satyam">S.

This study opens an avenue to clinical studies to demonstrate the validity of this paradigm as a nutritional food supplement, which could improve the clinical outcome of patients subjected to percutaneous angioplasty. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grape%20seed%20extract" title="grape seed extract">grape seed extract</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20ischemia-reperfusion%20injury" title=" myocardial ischemia-reperfusion injury"> myocardial ischemia-reperfusion injury</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Zincovit%20tablets" title=" Zincovit tablets "> Zincovit tablets </a> </p> <a href="https://publications.waset.org/abstracts/13015/grape-seed-extract-and-zinc-containing-multivitamin-mineral-nutritional-food-supplement-protects-heart-against-myocardial-ischemic-reperfusion-injury-in-wistar-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13015.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">376</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">527</span> Investigation of Ezetimibe Administration on Cell Survival Markers in Kidney Ischemia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Heydari">Zahra Heydari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: One of the major clinical issues is acute renal failure, which is caused by ischemia-reperfusion of the kidney and is associated with high mortality. Despite advances in this area, important issues such as tissue necrosis, cell apoptosis, and so on in damaged tissue are suggestive for more researches and study on this subject. Objective: Evaluation of the potential utility of Ezetimibe in reducing injuries and cell death induced by kidney ischemia/ reperfusion through inducing expression changes of different cellular pathways in adult Sprague-Dawley rats. Materials and methods: Forty rats weighing 180-200g were divided into 4 groups. For this purpose, the first right kidneys of the rats were removed during surgery. After 20 days, the left renal artery was closed with a soft clamp and reperfusion was performed. After 24 hours, blood samples were collected and sent to the laboratory with kidneys to measure bax and bcl-2 by Western blotting and histopathological tests. Results: Quantitative damage reviews of Kidney tissue indicates damage Acute and severe tubular lesions were observed in the ischemia group. Also, the amount of injury was significantly reduced in the treatment group. There was also a significant difference between the ischemia and sham groups. In general, the results show that a single dose of 1.2 mg/kg of ezetimibe can reduce the bax/ bcl-2 ratio compared to the ischemia group. In general, the results showed Ezetimibe is effective in reducing cell damage and death due to ischemia/ reperfusion after renal ischemia through changes in the expression of various cellular pathways in rats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20renal%20failure" title="acute renal failure">acute renal failure</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20ischemia-reperfusion%20injury" title=" renal ischemia-reperfusion injury"> renal ischemia-reperfusion injury</a>, <a href="https://publications.waset.org/abstracts/search?q=ezetimibe" title=" ezetimibe"> ezetimibe</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a> </p> <a href="https://publications.waset.org/abstracts/140497/investigation-of-ezetimibe-administration-on-cell-survival-markers-in-kidney-ischemia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140497.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">196</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">526</span> Exploring the Efficacy of Nitroglycerin in Filler-Induced Facial Skin Ischemia: A Narrative ‎Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Feily">Amir Feily</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazhir%20Shahmoradi%20Akram"> Hazhir Shahmoradi Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Ghaedi"> Mojtaba Ghaedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farshid%20Javdani"> Farshid Javdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Naser%20Hatami"> Naser Hatami</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Kalani"> Navid Kalani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Zarenezhad"> Mohammad Zarenezhad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Filler-induced facial skin ischemia is a potential complication of dermal filler injections that can result in tissue damage and necrosis. Nitroglycerin has been suggested as a treatment option due to its vasodilatory effects, but its efficacy in this context is unclear. Methods: A narrative review was conducted to examine the available evidence on the efficacy of nitroglycerin in filler-induced facial skin ischemia. Relevant studies were identified through a search of electronic databases and manual searching of reference lists. Results: The review found limited evidence supporting the efficacy of nitroglycerin in this context. While there were case reports where the combination of nitroglycerin and hyaluronidase was successful in treating filler-induced facial skin ischemia, there was only one case report where nitroglycerin alone was successful. Furthermore, a rat model did not demonstrate any benefits of nitroglycerin and showed harmful results. Conclusion: The evidence regarding the efficacy of nitroglycerin in filler-induced facial skin ischemia is inconclusive and seems to be against its application. Further research is needed to determine the effectiveness of nitroglycerin alone and in combination with other treatments for this condition. Clinicians should consider limited evidence bases when deciding on treatment options for patients with filler-induced facial skin ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitroglycerin" title="nitroglycerin">nitroglycerin</a>, <a href="https://publications.waset.org/abstracts/search?q=facial" title=" facial"> facial</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20ischemia" title=" skin ischemia"> skin ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=fillers" title=" fillers"> fillers</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy" title=" efficacy"> efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative%20review" title=" narrative review"> narrative review</a> </p> <a href="https://publications.waset.org/abstracts/171621/exploring-the-efficacy-of-nitroglycerin-in-filler-induced-facial-skin-ischemia-a-narrative-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171621.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">92</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">525</span> Utility of Cardiac Biomarkers in Combination with Exercise Stress Testing in Patients with Suspected Ischemic Heart Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rawa%20Delshada">Rawa Delshada</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanaa%20G.%20Hamab"> Sanaa G.

They were classified into two groups: patients with positive exercise stress test results (n=40) and control group with negative exercise stress test results (n=40). Serum concentration of troponin I, Heart-type Fatty Acid Binding Protein (H-FABP) and Ischemia Modified Albumin (IMA) were measured one hour after performing stress test. Enzyme Linked Immunosorbent Assay was used to measure both troponin I, H-FABP levels, while IMA levels were measured by albumin cobalt binding test. There was no statistically significant difference in the mean concentration of troponin I between two groups (0.75±0.55ng/ml) for patients with positive test result vs. (0.71±0.55ng/ml) for negative test result group with P>0.05. Contrary to our expectation, mean IMA level was slightly higher among control group (70.88±39.76U/ml) compared to (62.7±51.9U/ml) in positive test result group, but still with no statistically significant difference (P>0.05). Median H-FABP level was also higher among negative exercise stress testing group compared the positive one (2ng/ml vs. 1.9ng/ml respectively), but failed to reach statistically significant difference (P>0.05). When quartiles model used to explore the possible association between each study biomarkers with the others; serum H-FABP level was lowest (1.7ng/ml) in highest quartile of IMA and lowest H-FABP (1.8ng/ml) in highest quartile of troponin I but with no statistically significant association (P>0.05). Myocardial ischemia, more likely occurred after exercise stress test, is not capable of causing troponin I release. Furthermore, an increase in H-FABP and IMA levels after stress test are not reflecting myocardial ischemia. Moreover, the combination of troponin I, H-FABP and IMA after measuring their post exercise levels does not improve the diagnostic utility of exercise stress test enormously. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20biomarkers" title="cardiac biomarkers">cardiac biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemic%20heart%20disease" title=" ischemic heart disease"> ischemic heart disease</a>, <a href="https://publications.waset.org/abstracts/search?q=troponin%20I" title=" troponin I"> troponin I</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia%20modified%20albumin" title=" ischemia modified albumin"> ischemia modified albumin</a>, <a href="https://publications.waset.org/abstracts/search?q=heart-type%20fatty%20acid%20binding%20protein" title=" heart-type fatty acid binding protein"> heart-type fatty acid binding protein</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise%20stress%20testing" title=" exercise stress testing"> exercise stress testing</a> </p> <a href="https://publications.waset.org/abstracts/57016/utility-of-cardiac-biomarkers-in-combination-with-exercise-stress-testing-in-patients-with-suspected-ischemic-heart-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57016.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">249</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">524</span> Inhibition of Glutamate Carboxypeptidase Activity Protects Retinal Ganglionic Cell Death Induced by Ischemia-Reperfusion by Reducing the Astroglial Activation in Rat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dugeree%20Otgongerel">Dugeree Otgongerel</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyong%20Jin%20Cho"> Kyong Jin Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Han%20Kim"> Yu-Han Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sangmee%20Ahn%20Jo"> Sangmee Ahn Jo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Excessive activation of glutamate receptor is thought to be involved in retinal ganglion cell (RGC) death after ischemia- reperfusion damage. Glutamate carboxypeptidase II (GCPII) is an enzyme responsible for the synthesis of glutamate. Several studies showed that inhibition of GCPII prevents or reduces cellular damage in brain diseases. Thus, in this study, we examined the expression of GCPII in rat retina and the role of GCPII in acute high IOP ischemia-reperfusion damage of eye by using a GCPII inhibitor, 2-(phosphonomethyl) pentanedioic acid (2-PMPA). Animal model of ischemia-reperfusion was induced by raising the intraocular pressure for 60 min and followed by reperfusion for 3 days. Rats were randomly divided into four groups: either intra-vitreous injection of 2-PMPA (11 or 110 ng per eye) or PBS after ischemia-reperfusion, 2-PMPA treatment without ischemia-reperfusion and sham-operated normal control. GCPII immunoreactivity in normal rat retina was detected weakly in retinal nerve fiber layer (RNFL) and retinal ganglionic cell layer (RGL) and also inner plexiform layer (IPL) and outer plexiform layer (OPL) strongly where are co-stained with an anti-GFAP antibody, suggesting that GCPII is expressed mostly in Muller and astrocytes. Immunostaining with anti-BRN antibody showed that ischemia- reperfusion caused RGC death (31.5 %) and decreased retinal thickness in all layers of damaged retina, but the treatment of 2-PMPA twice at 0 and 48 hour after reperfusion blocked these retinal damages. GCPII level in RNFL layer was enhanced after ischemia-reperfusion but was blocked by PMPA treatment. This result was confirmed by western blot analysis showing that the level of GCPII protein after ischemia- reperfusion increased by 2.2- fold compared to control, but this increase was blocked almost completely by 110 ng PMPA treatment. Interestingly, GFAP immunoreactivity in the retina after ischemia- reperfusion followed by treatment with PMPA showed similar pattern to GCPII, increase after ischemia-reperfusion but reduction to the normal level by PMPA treatment. Our data demonstrate that increase of GCPII protein level after ischemia-reperfusion injury is likely to cause glial activation and/or retinal cell death which are mediated by glutamate, and GCPII inhibitors may be useful in treatment of retinal disorders in which glutamate excitotoxicity is pathogenic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glutamate%20carboxypepptidase%20II" title="glutamate carboxypepptidase II">glutamate carboxypepptidase II</a>, <a href="https://publications.waset.org/abstracts/search?q=glutamate%20excitotoxicity" title=" glutamate excitotoxicity"> glutamate excitotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia-reperfusion" title=" ischemia-reperfusion"> ischemia-reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20ganglion%20cell" title=" retinal ganglion cell"> retinal ganglion cell</a> </p> <a href="https://publications.waset.org/abstracts/39644/inhibition-of-glutamate-carboxypeptidase-activity-protects-retinal-ganglionic-cell-death-induced-by-ischemia-reperfusion-by-reducing-the-astroglial-activation-in-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39644.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">523</span> Relationship of Silent Myocardial Ischemia to Erectile Dysfunction in Patients with Diabetes Mellitus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kassem">Ali Kassem</a>, <a href="https://publications.waset.org/abstracts/search?q=Esam%20Nada"> Esam Nada</a>, <a href="https://publications.waset.org/abstracts/search?q=Amro%20Abdelhamed"> Amro Abdelhamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Shigeo%20Horie"> Shigeo Horie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Diabetes mellitus (DM) is associated with macrovascular complications, including coronary artery disease (CAD), and microvascular complications that contribute to the pathogenesis of erectile dysfunction (ED). On the other hand, silent myocardial ischemia (SMI) is more common in diabetic patients and is a strong predictor of cardiac events and mortality in diabetic and non-diabetic patients. Recently, Multidetector computed tomographic coronary angiography (MDCT-CA) has become a reliable non-invasive imaging modality for screening diabetic patients for SMI. We aim to evaluate the presence of SMI using (MDCT-CA) in patients with type 2DM having ED. Methods: This study evaluated 20 patients (mean age 61.45 ± 10.7 years), with DM and ED without any history of angina or angina equivalent. ED was tested with the Sexual Health Inventory for Men score, erection hardness score (EHS), and maximal penile circumferential change by an erect meter. Results: Of twenty studied patients, coronary artery stenosis was detected in 13 (65%) patients in the form of one-vessel disease (n = 6, 30%), two-vessel disease (n = 2, 10%), and three-vessel disease (n = 5, 25%). Maximum coronary artery stenosis was positively correlated with age (P < 0.016,) and negatively correlated with EHS (P <04). Multivariate regression analysis using age and EHS showed that age was the only independent predictor of SMI (P <04). Conclusion: MDCT-CA is a useful tool to identify SMI in patients with diabetes mellitus and ED. One should consider the possibility of SMI especially in elderly patients with DM who have ED. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title="diabetes mellitus">diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=erectile%20dysfunction" title=" erectile dysfunction"> erectile dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=microvascular" title=" microvascular"> microvascular</a>, <a href="https://publications.waset.org/abstracts/search?q=silent%20ischemia" title=" silent ischemia"> silent ischemia</a> </p> <a href="https://publications.waset.org/abstracts/94695/relationship-of-silent-myocardial-ischemia-to-erectile-dysfunction-in-patients-with-diabetes-mellitus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94695.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">173</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">522</span> A Second Chance to Live and Move: Lumbosacral Spinal Cord Ischemia-Infarction after Cardiac Arrest and the Artery of Adamkiewicz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Demian">Anna Demian</a>, <a href="https://publications.waset.org/abstracts/search?q=Levi%20Howard"> Levi Howard</a>, <a href="https://publications.waset.org/abstracts/search?q=L.%20Ng"> L.

David Freeman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Out-of-hospital cardiac arrest (OHCA) can carry a high mortality. For survivors, the most common complication is hypoxic-ischemic brain injury (HIBI). Rarely, lumbosacral spinal cord and/or other spinal cord artery ischemia can occur due to anatomic variation and variable mean arterial pressure after the return of spontaneous circulation. We present a case of an OHCA survivor who later woke up with bilateral leg weakness with preserved sensation (ASIA grade B, L2 level). Methods: We describe a clinical, radiographic, and laboratory presentation, as well as a National Library of Medicine (NLM) search engine methodology, characterizing incidence/prevalence of this entity is discussed. A 70-year-old male, a longtime smoker, and alcohol user, suddenly collapsed at a bar surrounded by friends. He had complained of chest pain before collapsing. 911 was called. EMS arrived, and the patient was in pulseless electrical activity (PEA), cardiopulmonary resuscitation (CPR) was initiated, and the patient was intubated, and a LUCAS device was applied for continuous, high-quality CPR in the field by EMS. In the ED, central lines were placed, and thrombolysis was administered for a suspected Pulmonary Embolism (PE). It was a prolonged code that lasted 90 minutes. The code continued with the eventual return of spontaneous circulation. The patient was placed on an epinephrine and norepinephrine drip to maintain blood pressure. ECHO was performed and showed a “D-shaped” ventricle worrisome for PE as well as an ejection fraction around 30%. A CT with PE protocol was performed and confirmed bilateral PE. Results: The patient woke up 24 hours later, following commands, and was extubated. He was found paraplegic below L2 with preserved sensation, with hypotonia and areflexia consistent with “spinal shock” or anterior spinal cord syndrome. MRI thoracic and lumbar spine showed a conus medullaris level spinal cord infarction. The patient was given IV steroids upon initial discovery of cord infarct. NLM search using “cardiac arrest” and “spinal cord infarction” revealed 57 results, with only 8 review articles. Risk factors include age, atherosclerotic disease, and intraaortic balloon pump placement. AoA (Artery of Adamkiewicz) anatomic variation along with existing atherosclerotic factors and low perfusion were also known risk factors. Conclusion: Acute paraplegia from anterior spinal cord infarction of the AoA territory after cardiac arrest is rare. Larger prospective, multicenter trials are needed to examine potential interventions of hypothermia, lumbar drains, which are sometimes used in aortic surgery to reduce ischemia and/or other neuroprotectants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20arrest" title="cardiac arrest">cardiac arrest</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20cord%20infarction" title=" spinal cord infarction"> spinal cord infarction</a>, <a href="https://publications.waset.org/abstracts/search?q=artery%20of%20Adamkiewicz" title=" artery of Adamkiewicz"> artery of Adamkiewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=paraplegia" title=" paraplegia"> paraplegia</a> </p> <a href="https://publications.waset.org/abstracts/141427/a-second-chance-to-live-and-move-lumbosacral-spinal-cord-ischemia-infarction-after-cardiac-arrest-and-the-artery-of-adamkiewicz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141427.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">189</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">521</span> Study of Silent Myocardial Ischemia in Type 2 Diabeic Males: Egyptian Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kassem">Ali Kassem</a>, <a href="https://publications.waset.org/abstracts/search?q=Yhea%20Kishik"> Yhea Kishik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hassan"> Ali Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdelwahab"> Mohamed Abdelwahab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Accelerated coronary and peripheral vascular atherosclerosis is one of the most common and chronic complications of diabetes mellitus. A recent aspect of coronary artery disease in this condition is its silent nature. The aim of the work: Detection of the prevalence of silent myocardial ischemia (SMI) in Upper Egypt type 2 diabetic males and to select male diabetic population who should be screened for SMI. Patients and methods: 100 type 2 diabetic male patients with a negative history of angina or anginal equivalent symptoms and 30 healthy control were included. Full medical history and thorough clinical examination were done for all participants. Fasting and post prandial blood glucose level, lipid profile, (HbA1c), microalbuminuria, and C-reactive protein were done for all participants Resting ECG, trans-thoracic echocardiography, treadmill exercise ECG, myocardial perfusion imaging were done for all participants and patients positive for one or more NITs were subjected for coronary angiography. Results Twenty nine patients (29%) were positive for one or more NITs in the patients group compared to only one case (3.3%) in the controls. After coronary angiography, 20 patients were positive for significant coronary artery stenosis in the patients group, while it was refused to be done by the patient in the controls. There were statistical significant difference between the two groups regarding, hypertension, dyslipidemia and obesity, family history of DM and IHD with higher levels of microalbuminuria, C-reactive protein, total lipids in patient group versus controls According to coronary angiography, patients were subdivided into two subgroups, 20 positive for SMI (positive for coronary angiography) and 80 negative for SMI (negative for coronary angiography). No statistical difference regarding family history of DM and type of diabetic therapy was found between the two subgroups. Yet, smoking, hypertension, obesity, dyslipidemia and family history of IHD were significantly higher in diabetics positive versus those negative for SMI. 90% of patients in subgroup positive for SMI had two or more cardiac risk factors while only two patients had one cardiac risk factor (10%). Uncontrolled DM was detected more in patients positive for SMI. Diabetic complications were more prevalent in patients positive for SMI versus those negative for SMI. Most of the patients positive for SMI have DM more than 5 years duration. Resting ECG and resting Echo detected only 6 and 11 cases, respectively, of the 20 positive cases in group positive for SMI compared to treadmill exercise ECG and myocardial perfusion imaging that detected 16 and 18 cases respectively, Conclusion: Type 2 diabetic male patients should be screened for detection of SMI when aged above 50 years old, diabetes duration is more than 5 years, presence of two or more cardiac risk factors and/or patients suffering from one or more of the chronic diabetic complications. CRP, is an important parameter for selection of type 2 diabetic male patients who should be screened for SMI. Non invasive cardiac tests are reliable for screening of SMI in these patients in our locality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=C-reactive%20protein" title="C-reactive protein">C-reactive protein</a>, <a href="https://publications.waset.org/abstracts/search?q=Silent%20myocardial%20ischemia" title=" Silent myocardial ischemia"> Silent myocardial ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=Stress%20tests" title=" Stress tests"> Stress tests</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20DM" title=" type 2 DM"> type 2 DM</a> </p> <a href="https://publications.waset.org/abstracts/36498/study-of-silent-myocardial-ischemia-in-type-2-diabeic-males-egyptian-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36498.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">385</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">520</span> Albendazole Ameliorates Inflammatory Response in a Rat Model of Acute Mesenteric Ischemia Reperfusion Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamyar%20Moradi">Kamyar Moradi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Acute mesenteric ischemia is known as a life-threatening condition. Re-establishment of blood flow in this condition can lead to mesenteric ischemia reperfusion (MIR) injury, which is accompanied by inflammatory response. Still, clear blueprint of inflammatory mechanism underlying MIR injury has not been provided. Interestingly, Albendazole has exhibited notable effects on inflammation and cytokine production. In this study, we aimed to evaluate outcomes of MIR injury following pretreatment with Albendazole with respect to assessment of mesenteric inflammation and ischemia threshold. Methods: Male rats were randomly divided into sham operated, vehicle treated, Albendazole 100 mg/kg, and Albendazole 200 mg/kg groups. MIR injury was induced by occlusion of superior mesenteric artery for 30 minutes followed by 120 minutes of reperfusion. Samples were utilized for assessment of epithelial survival and villous height. Immunohistochemistry study revealed intestinal expression of TNF-α and HIF-1-α. Gene expression of NF-κB/TLR4/TNF-α/IL-6 was measured using RTPCR. Also, protein levels of inflammatory cytokines in serum and intestine were assessed by ELISA method. Results: Histopathological study demonstrated that pretreatment with Albendazole could ameliorate decline in villous height and epithelial survival following MIR injury. Also, systemic inflammation was suppressed after administration of Albendazole. Analysis of possible participating inflammatory pathway could demonstrate that intestinal expression of NF-κB/TLR4/TNF-α/IL-6 is significantly attenuated in treated groups. Eventually, IHC study illustrated concordant decline in mesenteric expression of HIF-1-α/TNF-α. Conclusion: Single dose pretreatment with Albendazole could ameliorate inflammatory response and enhance ischemia threshold following induction of MIR injury. Still, more studies would clarify existing causality in this phenomenon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=albendazole" title="albendazole">albendazole</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia%20reperfusion%20injury" title=" ischemia reperfusion injury"> ischemia reperfusion injury</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenteric%20ischemia" title=" mesenteric ischemia"> mesenteric ischemia</a> </p> <a href="https://publications.waset.org/abstracts/146614/albendazole-ameliorates-inflammatory-response-in-a-rat-model-of-acute-mesenteric-ischemia-reperfusion-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146614.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">169</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">519</span> Memory Types in Hemodialysis (HD) Patients; A Study Based on Hemodialysis Duration, Zahedan: South East of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behnoush%20Sabayan">Behnoush Sabayan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Alidadi"> Ali Alidadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeid%20Ebarhimi"> Saeid Ebarhimi</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20M.%20Bakhshani"> N.

We studied the brain abnormalities in HD patients. The aim of this study was to investigate the effect of long term HD on brain structure of HD patients. Non-contrast MRI was used to evaluate imaging findings. Our study included 80 HD patients of whom 39 had less than six months of HD and 41 patients had a history of HD more than six months. The population had a mean age of 51.60 years old and 27.5% were female. According to study, HD patients who have been hemodialyzed for a long time (median time of HD was up to 4 years) had small vessel ischemia than the HD patients who underwent HD for a shorter term, which the median time was 3 to 5 months. Most of the small vessel ischemia was located in pre-ventricular, subcortical and white matter (1.33± .471, 1.23± .420 and 1.39±.490). However, the other brain damages like: central pons abnormality, global brain atrophy, thinning of corpus callosum and frontal lobe atrophy were found (P<0.01). The present study demonstrated that HD patients who were under HD for a longer time had small vessel ischemia and we conclude that this small vessel ischemia might be a causative mechanism of brain atrophy in chronic hemodialysis patients. However, additional researches are needed in this area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hemodialysis%20Patients" title="Hemodialysis Patients">Hemodialysis Patients</a>, <a href="https://publications.waset.org/abstracts/search?q=Duration%20of%20Hemodialysis" title=" Duration of Hemodialysis"> Duration of Hemodialysis</a>, <a href="https://publications.waset.org/abstracts/search?q=MRI" title=" MRI"> MRI</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahedan" title=" Zahedan"> Zahedan</a> </p> <a href="https://publications.waset.org/abstracts/83278/memory-types-in-hemodialysis-hd-patients-a-study-based-on-hemodialysis-duration-zahedan-south-east-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83278.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">213</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">518</span> Mesenteric Ischemia Presenting as Acalculous Cholecystitis: A Case Review of a Rare Complication and Aberrant Anatomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joshua%20Russell">Joshua Russell</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Zubair"> Omar Zubair</a>, <a href="https://publications.waset.org/abstracts/search?q=Reuben%20Ndegwa"> Reuben Ndegwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Mesenteric ischemia is an uncommon condition that can be challenging to diagnose in the acute setting, with the potential for significant morbidity and mortality. Very rarely has acute acalculous cholecystitis been described in the setting of mesenteric ischemia. Case: This was the case in a 78-year-old male, who initially presented with clinical and radiological evidence of small bowel obstruction, thought likely secondary to malignancy. The patient had a 6-week history of anorexia, worsening lower abdominal pain, and ~30kg of unintentional weight loss over a 12-month period and a CT- scan demonstrated a transition point in the distal ileum. The patient became increasingly hemodynamically unstable and peritonitic, and an emergency laparotomy was performed. Intra-operatively, however, no obvious transition point was identified, and instead, the gallbladder was markedly gangrenous and oedematous, consistent with acalculous cholecystitis. An open total cholecystectomy was subsequently performed. The patient was admitted to the Intensive Care Unit post-operatively and continued to deteriorate over the proceeding 48 hours, with two re-look laparotomies demonstrating progressively worsening bowel ischemia, initially in the distribution of the superior mesenteric artery and then the coeliac trunk. On review, the patient was found to have an aberrant right hepatic artery arising from the superior mesenteric artery. The extent of ischemia was considered non-survivable, and the patient was palliated. Discussion: Multiple theories currently exist for the underlying pathophysiology of acalculous cholecystitis, including biliary stasis, sepsis, and ischemia. This case lends further support to ischemia as the underlying etiology of acalculous cholecystitis. This is particularly the case when considered in the context of the patient’s aberrant right hepatic artery arising from the superior mesenteric artery, which occurs in 11-14% of patients. Conclusion: This case report adds further insight to the debate surrounding the pathophysiology of acalculous cholecystitis. It also presents acalculous cholecystitis as a complication of mesenteric ischemia that should always be considered, especially in the elderly patient and in the context of relatively common anatomical variations. Furthermore, the case brings to attention the importance of maintaining dynamic working diagnoses in the setting of evolving pathophysiology and clinical presentations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acalculous%20cholecystitis" title="acalculous cholecystitis">acalculous cholecystitis</a>, <a href="https://publications.waset.org/abstracts/search?q=anatomical%20variation" title=" anatomical variation"> anatomical variation</a>, <a href="https://publications.waset.org/abstracts/search?q=general%20surgery" title=" general surgery"> general surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=mesenteric%20ischemia" title=" mesenteric ischemia"> mesenteric ischemia</a> </p> <a href="https://publications.waset.org/abstracts/139081/mesenteric-ischemia-presenting-as-acalculous-cholecystitis-a-case-review-of-a-rare-complication-and-aberrant-anatomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139081.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">191</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">517</span> Possible Neuroprotective Mechanism of Remote Limb Ischemic Post Conditioning against Global Cerebral Ischemic Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sruthi%20Ramagiri">Sruthi Ramagiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajeev%20Taliyan"> Rajeev Taliyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and purpose: Recent investigations on ischemia and reperfusion injury postulate that transient ischemia of remote organs after a prolonged ischemic insult confers neuroprotection. However, the molecular mechanisms of the remote limb ischemic post-conditioning (RIPOC) are yet to be elucidated. The current study was designed to investigate the protective mechanism of RIPOC against cerebral ischemic injury using global model of stroke. Materials and methods: Global ischemic reperfusion injury (IR) was achieved by 30 minutes ischemia of cerebral artery, followed by reperfusion for 24 hours. Induction of global ischemia was followed by 4 brief episodes (30 seconds each) of ischemia and reperfusion of femoral artery to accomplish RIPOC. 5-Hydroxy Decanoic acid (5-HD), a KATP channel blocker (20 mg/kg) was administered after induction of global ischemia and RIPOC intervention. Results: IR injury ensue significant behavioural deficits as manifested by rotarod performance and spontaneous locomotor activity when compared to sham control. Furthermore, IR injury significantly increased oxidonitrative stress and infarct volume as evidenced by biochemical parameters (MDA, GSH, Nitrite, SOD) and 2,3,5-triphenyltetrazolium chloride (TTC) staining respectively. Moreover, RIPOC intervention ameliorated the behavioural performance, attenuated the oxidative stress and infarct volume when compared to IR injury group. However, administration of 5-HD increased the oxidative stress and infarct size while deteriorating the behavioural parameters when compared to RIPOC group. Conclusions: In a nutshell, cerebral IR injury has significantly induced the neuronal damage, whereas RIPOC intervention decreased the neuronal injury. Moreover, 5-HD abolished the neuroprotection offered by RIPOC indicating the putative role of KATP channel opening in RIPOC against cerebral ischemic injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RIPOC" title="RIPOC">RIPOC</a>, <a href="https://publications.waset.org/abstracts/search?q=cerebral%20injury" title=" cerebral injury"> cerebral injury</a>, <a href="https://publications.waset.org/abstracts/search?q=KATP%20channel" title=" KATP channel"> KATP channel</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroprotection" title=" neuroprotection"> neuroprotection</a> </p> <a href="https://publications.waset.org/abstracts/16163/possible-neuroprotective-mechanism-of-remote-limb-ischemic-post-conditioning-against-global-cerebral-ischemic-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16163.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">470</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">516</span> Syndecan -1 as Regulator of Ischemic-Reperfusion Damage Limitation in Experiment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20E.%20Kolpakova">M.

The study of the mechanisms of reperfusion injury limitation by remote ischemic postconditioning (RC) is of interest due to the effects on functional recovery after cerebral ischemia. The goal of the study is the assessment of the role of syndecan-1 (SDC-1) in restriction of ischemic-reperfusion injury on middle cerebral artery model in rats using RC protocol. Randomized controlled trials were conducted. Ischemia was performed by middle cerebral artery occlusion by Belayev L. (1996) on the Wistar rat-males (n= 87) weighting 250 ± 50 g. under general anesthesia (Zoletil 100 и Xylazine 2%). Syndecan-1 (SDC-1) concentration difference in plasma samples of false operated animals and animals with brain ischemia was 30% (30 min. МСАо: 41.4 * ± 1.3 ng/ml). SDC-1 concentration in animal plasma samples with ischemia + RC protocol was 112% (30 min МСАо+ RC): 67.8**± 5.8 ng/ml). Calculation of infarction volume in the ischemia group revealed brain injury in 31.97 ± 2.5%; the volume of infarction was 13.6 ± 1.3% in 30 min. МCАо + RC group. Swelling of tissue in the group 30 min. МCАо + RC was 16 ± 2.1%; it was 47 ± 3.3%. in 30 min. МCАо group. Correlation analysis showed a high direct correlation relationship between infarct area and muscle strength in the right forelimb (КК=0.72) in the 30 min. МCАо + RC group. Correlation analysis showed very high inverse correlation between infarct area and capillary blood flow in the 30 min. МCАо + RC group (p <0.01; r = -0.98). We believe the SDC-1 molecule in blood plasma may play role of potential messenger of ischemic-reperfusion injury restriction mechanisms. This leads to infarct-limiting effect of remote ischemic postconditioning and early functioning recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ischemia" title="ischemia">ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=%D0%9C%D0%A1%D0%90%D0%BE" title=" МСАо"> МСАо</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20ischemic%20postconditioning" title=" remote ischemic postconditioning"> remote ischemic postconditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=syndecan-1" title=" syndecan-1"> syndecan-1</a> </p> <a href="https://publications.waset.org/abstracts/179202/syndecan-1-as-regulator-of-ischemic-reperfusion-damage-limitation-in-experiment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179202.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">62</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">515</span> Calculation the Left Ventricle Wall Radial Strain and Radial SR Using Tagged Magnetic Resonance Imaging Data (tMRI)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Alenezy">Mohammed Alenezy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The function of cardiac motion can be used as an indicator of the heart abnormality by evaluating longitudinal, circumferential, and Radial Strain of the left ventricle. In this paper, the Radial Strain and SR is studied using tagged MRI (tMRI) data during the cardiac cycle on the mid-ventricle level of the left ventricle. Materials and methods: The short-axis view of the left ventricle of five healthy human (three males and two females) and four healthy male rats were imaged using tagged magnetic resonance imaging (tMRI) technique covering the whole cardiac cycle on the mid-ventricle level. Images were processed using Image J software to calculate the left ventricle wall Radial Strain and radial SR. The left ventricle Radial Strain and radial SR were calculated at the mid-ventricular level during the cardiac cycle. The peak Radial Strain for the human and rat heart was 40.7±1.44, and 46.8±0.68 respectively, and it occurs at 40% of the cardiac cycle for both human and rat heart. The peak diastolic and systolic radial SR for human heart was -1.78 s-1 ± 0.02 s-1 and 1.10±0.08 s-1 respectively, while for rat heart it was -5.16± 0.23s-1 and 4.25±0.02 s-1 respectively. Conclusion: This results show the ability of the tMRI data to characterize the cardiac motion during the cardiac cycle including diastolic and systolic phases which can be used as an indicator of the cardiac dysfunction by estimating the left ventricle Radial Strain and radial SR at different locations of the cardiac tissue. This study approves the validity of the tagged MRI data to describe accurately the cardiac radial motion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=left%20ventricle" title="left ventricle">left ventricle</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20strain" title=" radial strain"> radial strain</a>, <a href="https://publications.waset.org/abstracts/search?q=tagged%20MRI" title=" tagged MRI"> tagged MRI</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20cycle" title=" cardiac cycle"> cardiac cycle</a> </p> <a href="https://publications.waset.org/abstracts/21036/calculation-the-left-ventricle-wall-radial-strain-and-radial-sr-using-tagged-magnetic-resonance-imaging-data-tmri" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21036.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">483</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">514</span> Automatic LV Segmentation with K-means Clustering and Graph Searching on Cardiac MRI</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hae-Yeoun%20Lee">Hae-Yeoun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quantification of cardiac function is performed by calculating blood volume and ejection fraction in routine clinical practice.

The transient middle cerebral artery occlusion model (MCAO) is considered to be a reliable and reproducible rodent model of cerebral ischemia. The purpose of the current study was to examine the neuroprotective effects of Crocus sativus (saffron) in a rat model of left middle cerebral artery MCAO. Male Wistar rats were anesthetized and subjected to 1 h of MCAO followed by 48 h reperfusion or sham surgery. One group of the ischemia operated animals was kept as left brain ischemia/reperfusion (I/R). Another 2 operated groups received saffron extract (100 or 200 mg/kg, i.p) four times (60 min before the surgery, during the surgery, and on days 1 and 2 after the occlusion). During the experiment, behavioral tests were performed. After 72 h the animals were euthanized and their left brain hemispheres were used in the biochemical, histopathological, and immunohistochemical studies. Saffron administration revealed an improvement in I/R-induced alteration of locomotor balance and coordination ability of rats. Moreover, saffron decreased the brain content of malondialdehyde, nitric oxide, brain natriuretic peptide and vascular endothelial growth factor with significant increase of reduced glutathione. Immunohistochemical evaluation of caspase-3 and Bax protein expression revealed reduction in I/R-enhanced apoptosis in saffron treated rats. In conclusion, saffron treatment decreases ischemic brain injury in association with inhibition of apoptotic and oxidative cell death in a dose dependent manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=caspase-3" title="caspase-3">caspase-3</a>, <a href="https://publications.waset.org/abstracts/search?q=cerebral%20ischemia" title=" cerebral ischemia"> cerebral ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=Crocus%20sativus" title=" Crocus sativus"> Crocus sativus</a>, <a href="https://publications.waset.org/abstracts/search?q=rats" title=" rats"> rats</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular%20endothelial%20growth%20factor" title=" vascular endothelial growth factor"> vascular endothelial growth factor</a> </p> <a href="https://publications.waset.org/abstracts/70152/neuroprotective-effect-of-crocus-sativus-against-cerebral-ischemia-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70152.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">258</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">512</span> Impact of Pediatric Cardiac Rehabilitation on the Physical Condition of Children with Congenital Heart Defects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hady%20Atef%20Labib">Hady Atef Labib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pediatric cardiac rehabilitation has the potential to benefit many children with congenital heart defects (CHD). Instead of excellent surgical results most of children usually present with a depression of physical condition so early rehabilitation program is recommended to avoid that decline in physical tolerance and prevent any post surgical complications. Unfortunately, the limited experience with and availability of these programs has caused the benefits of cardiac rehabilitation to be unavailable to most children with CHD.

Oxidative stress develops from an imbalance between ROS production and reduced antioxidant defenses. Many enzymatic and nonenzymatic antioxidant systems including peroxiredoxins (Prxs) are present in kidney to maintain an appropriate level of ROS and prevent oxidative damage. Prxs are a family of peroxidases that reduce peroxides, with a conserved cysteine residue serving as the site of oxidation by peroxides. In this study, we examined the protective role of Prx V against I/R-induced acute kidney injury (AKI) using Prx V wild type (WT) and knockout (KO) mice. We compared the response of Prx V WT and KO mice in mice model of I/R injury. Renal structure, functions, oxidative stress markers, protein levels of oxidative damage marker were worse in Prx V KO mice. Ablation of Prx V enhanced susceptibility to I/R-induced oxidative stress. Prx V KO mice were seen to have more severe renal damage than Prx V WT mice in mice model of I/R injury. Our results demonstrate that Prx V is protective against I/R-induced AKI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peroxiredoxin" title="peroxiredoxin">peroxiredoxin</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia%2Freperfusion" title=" ischemia/reperfusion"> ischemia/reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney" title=" kidney"> kidney</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a> </p> <a href="https://publications.waset.org/abstracts/47859/protective-role-of-peroxiredoxin-v-against-ischemiareperfusion-induced-acute-kidney-injury-in-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47859.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">386</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">510</span> Quality Assurance in Cardiac Disorder Detection Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Naveed">Anam Naveed</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Andleeb"> Asma Andleeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehreen%20Sirshar"> Mehreen Sirshar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the article, Image processing techniques have been applied on cardiac images for enhancing the image quality. Two types of methodologies considers for survey, invasive techniques and non-invasive techniques. Different image processes for improvement of cardiac image quality and reduce the amount of radiation exposure for invasive techniques are explored. Different image processing algorithms for enhancing the noninvasive cardiac image qualities are described. Beside these two methodologies, third methodology has applied on live streaming of heart rate on ECG window for extracting necessary information, removing noise and enhancing quality. Sensitivity analyses have been carried out to investigate the impacts of cardiac images for diagnosis of cardiac arteries disease and how the enhancement on images will help the cardiologist to diagnoses disease. The paper evaluates strengths and weaknesses of different techniques applied for improved the image quality and draw a conclusion. Some specific limitations must be considered for whole survey, like the patient heart beat must be 70-75 beats/minute while doing the angiography, similarly patient weight and exposure radiation amount has some limitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20images" title="cardiac images">cardiac images</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20angiography" title=" CT angiography"> CT angiography</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20analysis" title=" critical analysis"> critical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20radiation" title=" exposure radiation"> exposure radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20techniques" title=" invasive techniques"> invasive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20techniques" title=" invasive techniques"> invasive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20techniques" title=" non-invasive techniques"> non-invasive techniques</a> </p> <a href="https://publications.waset.org/abstracts/26171/quality-assurance-in-cardiac-disorder-detection-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26171.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">352</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">509</span> Out of Hospital Cardiac Arrest in Kuala Lumpur: A Mixed Method Study on Incidence, Adherence to Protocol, and Issues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Said%20Nurumal">Mohd Said Nurumal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Sheikh%20Abdul%20Karim"> Sarah Sheikh Abdul Karim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information regarding out of hospital cardiac arrest incidence include outcome in Malaysia is limited and fragmented. This study aims to identify incidence and adherence to protocol of out of hospital cardiac arrest and also to explore the issues faced by the pre-hospital personnel in regards managing cardiac arrest victim in Kuala Lumpur, Malaysia. A mixed method approach combining the qualitative and quantitative study design was used. The 285 pre-hospital care data sheet of out of hospital cardiac arrest during the year of 2011 were examined by using checklists for identify the incidence and adherence to protocol. Nine semi-structured interviews and two focus group discussions were performed. For the incidence based on the overall out of hospital cardiac arrest cases that occurred in 2011 (n=285), the survival rates were 16.8%. For adherence to protocol, only 89 (41.8%) of the cases adhered to the given protocol and 124 did not adhere to such protocol. The qualitative information provided insight about the issues related to out of hospital cardiac arrest in every aspect. All the relevant qualitative data were merged into few categories relating issues that could affect the management of out of hospital cardiac arrest performed by pre-hospital care team. One of the essential elements in the out of hospital cardiac arrest handling by pre-hospital care is to ensure increase of survival rates and excellent outcomes by adhering to given protocols based on international standard benchmarks. Measures are needed to strengthen the quick activation of the pre-hospital care service, prompt bystander cardiopulmonary resuscitation, early defibrillation and timely advanced cardiac life support and also to tackle all the issues highlighted in qualitative results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-hospital%20care" title="pre-hospital care">pre-hospital care</a>, <a href="https://publications.waset.org/abstracts/search?q=out%20of%20hospital%20cardiac%20arrest" title=" out of hospital cardiac arrest"> out of hospital cardiac arrest</a>, <a href="https://publications.waset.org/abstracts/search?q=incidence" title=" incidence"> incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=protocol" title=" protocol"> protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20method%20research" title=" mixed method research"> mixed method research</a> </p> <a href="https://publications.waset.org/abstracts/12852/out-of-hospital-cardiac-arrest-in-kuala-lumpur-a-mixed-method-study-on-incidence-adherence-to-protocol-and-issues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12852.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">414</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">508</span> Wavelet-Based Classification of Myocardial Ischemia, Arrhythmia, Congestive Heart Failure and Sleep Apnea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santanu%20Chattopadhyay">Santanu Chattopadhyay</a>, <a href="https://publications.waset.org/abstracts/search?q=Gautam%20Sarkar"> Gautam Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabinda%20Das"> Arabinda Das</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents wavelet based classification of various heart diseases.

The main objective of the study was to assess the readiness of resuscitation teams during cardiac arrest and the organizational approaches that would best support their functioning in a new hospital facility, and to detect any factor that may have contributed to responses. This study analyses the readiness of Resuscitation Team (RT) during cardiac arrest. —Material and methods: A prospective Analytic design was carried out at a newly established United Nations level 2 hospital facility, on four RTM (resuscitation team member). A semi structured questionnaire was used to collect data. —Results: This study highlights indicate that the response time during cardiac arrest simulation meet both American heart association (AHA) and European resuscitation council guidelines. The study offers useful evidence about the impact of a new facility on RTM performance and provides an exposure of staff to emergency events within the Work setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20arrest" title="cardiac arrest">cardiac arrest</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20blue" title=" code blue"> code blue</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=resuscitation%20team%20member" title=" resuscitation team member"> resuscitation team member</a> </p> <a href="https://publications.waset.org/abstracts/75912/analyzing-the-readiness-of-resuscitation-team-during-cardiac-arrest" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75912.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">221</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">506</span> Possible Role of Fenofibrate and Clofibrate in Attenuated Cardioprotective Effect of Ischemic Preconditioning in Hyperlipidemic Rat Hearts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurfateh%20Singh">Gurfateh Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mu%20Khan"> Mu Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Razia%20Khanam"> Razia Khanam</a>, <a href="https://publications.waset.org/abstracts/search?q=Govind%20Mohan"> Govind Mohan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The present study has been designed to investigate the beneficial role of Fenofibrate & Clofibrate in attenuated the cardioprotective effect of ischemic preconditioning (IPC) in hyperlipidemic rat hearts. Materials & Methods: Experimental hyperlipidemia was produced by feeding high fat diet to rats for a period of 28 days. Isolated langendorff’s perfused normal and hyperlipidemic rat hearts were subjected to global ischemia for 30 min followed by reperfusion for 120 min. The myocardial infarct size was assessed macroscopically using triphenyltetrazolium chloride staining. Coronary effluent was analyzed for lactate dehydrogenase (LDH) and creatine kinase-MB release to assess the extent of cardiac injury. Moreover, the oxidative stress in heart was assessed by measuring thiobarbituric acid reactive substance, superoxide anion generation and reduced form of glutathione. Results: The ischemia-reperfusion (I/R) has been noted to induce oxidative stress by increasing TBARS, superoxide anion generation and decreasing reduced form of glutathione in normal and hyperlipidemic rat hearts. Moreover, I/R produced myocardial injury, which was assessed in terms of increase in myocardial infarct size, LDH and CK-MB release in coronary effluent and decrease in coronary flow rate in normal and hyperlipidemic rat hearts. In addition, the hyperlipidemic rat hearts showed enhanced I/R-induced myocardial injury with high degree of oxidative stress as compared with normal rat hearts subjected to I/R. Four episodes of IPC (5 min each) afforded cardioprotection against I/R-induced myocardial injury in normal rat hearts as assessed in terms of improvement in coronary flow rate and reduction in myocardial infarct size, LDH, CK-MB and oxidative stress. On the other hand, IPC mediated myocardial protection against I/R-injury was abolished in hyperlipidemic rat hearts. However, Treatment with Fenofibrate (100 mg/kg/day, i.p.), Clofibrate (300mg/kg/day, i.p.) as a agonists of PPAR-α have not affected the cardioprotective effect of IPC in normal rat hearts, but its treatment markedly restored the cardioprotective potentials of IPC in hyperlipidemic rat hearts. Conclusion: It is noted that the high degree of oxidative stress produced in hyperlipidemic rat heart during reperfusion and consequent down regulation of PPAR-α may be responsible to abolish the cardioprotective potentials of IPC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyperlipidemia" title="Hyperlipidemia">Hyperlipidemia</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia-reperfusion%20injury" title=" ischemia-reperfusion injury"> ischemia-reperfusion injury</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemic%20preconditioning" title=" ischemic preconditioning"> ischemic preconditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=PPAR-%CE%B1" title=" PPAR-α"> PPAR-α</a> </p> <a href="https://publications.waset.org/abstracts/41455/possible-role-of-fenofibrate-and-clofibrate-in-attenuated-cardioprotective-effect-of-ischemic-preconditioning-in-hyperlipidemic-rat-hearts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41455.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">288</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">505</span> Using Audit Tools to Maintain Data Quality for ACC/NCDR PCI Registry Abstraction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vikrum%20Malhotra">Vikrum Malhotra</a>, <a href="https://publications.waset.org/abstracts/search?q=Manpreet%20Kaur"> Manpreet Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayesha%20Ghotto"> Ayesha Ghotto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cardiac registries such as ACC Percutaneous Coronary Intervention Registry require high quality data to be abstracted, including data elements such as nuclear cardiology, diagnostic coronary angiography, and PCI. Introduction: The audit tool created is used by data abstractors to provide data audits and assess the accuracy and inter-rater reliability of abstraction performed by the abstractors for a health system. This audit tool solution has been developed across 13 registries, including ACC/NCDR registries, PCI, STS, Get with the Guidelines. Methodology: The data audit tool was used to audit internal registry abstraction for all data elements, including stress test performed, type of stress test, data of stress test, results of stress test, risk/extent of ischemia, diagnostic catheterization detail, and PCI data elements for ACC/NCDR PCI registries. This is being used across 20 hospital systems internally and providing abstraction and audit services for them. Results: The data audit tool had inter-rater reliability and accuracy greater than 95% data accuracy and IRR score for the PCI registry in 50 PCI registry cases in 2021. Conclusion: The tool is being used internally for surgical societies and across hospital systems. The audit tool enables the abstractor to be assessed by an external abstractor and includes all of the data dictionary fields for each registry. <p class="card-text"><strong>Keywords:</strong> <a
