Also, synovitis is common in advanced osteoarthritis. We aimed to evaluate the clinical, radiographic, and ultrasound findings in patients with knee osteoarthritis and to compare the clinical and imaging findings between knee osteoarthritis with and without synovial hypertrophy confirmed by ultrasound. Methods: One hundred knees (54 left, 46 right) in 95 patients (64 women, 31 men; mean age, 65.9 years; range, 43-85 years) with knee osteoarthritis were recruited. The Visual Analogue Scale (VAS) was used to assess the intensity of knee pain. The severity of knee osteoarthritis was classified according to Kellgren and Lawrence's (K-L) grade on a radiograph. Ultrasound examination was performed by a physiatrist who had 24 years of experience in musculoskeletal ultrasound. Ultrasound findings, including the thickness of joint effusion in the suprapatellar pouch, synovial hypertrophy, infrapatellar tendinosis, meniscal tear or extrusion, and Baker cyst, were measured and detected. The thickness of knee joint effusion was measured at the maximal anterior-posterior diameter of fluid collection in the suprapatellar pouch. Synovial hypertrophy was identified as the soft tissue of variable echogenicity, which is poorly compressible and nondisplaceable by compression of an ultrasound transducer. The knees were divided into two groups according to the presence of synovial hypertrophy. The differences in clinical and imaging findings between the two groups were evaluated by independent t-test and chi-square test. Results: Synovial hypertrophy was detected in 48 knees of 100 knees on ultrasound. There were no significant differences in demographic parameters and VAS score except in sex between the two groups (P<0.05). Medial meniscal extrusion and tear were significantly more frequent in knees with synovial hypertrophy than those in knees without synovial hypertrophy. K-L grade and joint effusion thickness were greater in patients with synovial hypertrophy than those in patients without synovial hypertrophy (P<0.05). Conclusion: Synovial hypertrophy in knee osteoarthritis was associated with greater suprapatellar joint effusion and higher K-L grade and maybe a characteristic ultrasound feature of late knee osteoarthritis. These results suggest that synovial hypertrophy on ultrasound can be regarded as a predictor of rapid progression in patients with knee osteoarthritis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knee%20osteoarthritis" title="knee osteoarthritis">knee osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20hypertrophy" title=" synovial hypertrophy"> synovial hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=K-L%20grade" title=" K-L grade"> K-L grade</a> </p> <a href="https://publications.waset.org/abstracts/165477/clinical-and-structural-differences-in-knee-osteoarthritis-withwithout-synovial-hypertrophy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165477.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">75</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">76</span> Evaluation of Osteoprotegrin (OPG) and Tumor Necrosis Factor A (TNF-A) Changes in Synovial Fluid and Serum in Dogs with Osteoarthritis; An Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Nikahval">Behrooz Nikahval</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Saeed%20Ahrari-Khafi"> Mohammad Saeed Ahrari-Khafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakineh%20Behroozpoor"> Sakineh Behroozpoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Nazifi"> Saeed Nazifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoarthritis (OA) is a progressive and degenerative condition of the articular cartilage and other joints’ structures. It is essential to diagnose this condition as early as possible. The present research was performed to measure the Osteoprotegrin (OPG) and Tumor Necrosis Factor α (TNF-α) in synovial fluid and blood serum of dogs with surgically transected cruciate ligament as a model of OA, to evaluate if measuring of these parameters can be used as a way of early diagnosis of OA. In the present study, four mature, clinically healthy dogs were selected to investigate the effect of experimental OA, on OPG and TNF-α as a way of early detection of OA. OPG and TNF-α were measured in synovial fluid and blood serum on days 0, 14, 28, 90 and 180 after surgical transaction of cranial cruciate ligament in one stifle joint. Statistical analysis of the results showed that there was a significant increase in TNF-α in both synovial fluid and blood serum. OPG showed a decrease two weeks after OA induction. However, it fluctuated afterward. In conclusion, TNF-α could be used in both synovial fluid and blood serum as a way of early detection of OA; however, further research still needs to be conducted on OPG values in OA detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title="osteoarthritis">osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoprotegrin" title=" osteoprotegrin"> osteoprotegrin</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20necrosis%20factor%20%CE%B1" title=" tumor necrosis factor α"> tumor necrosis factor α</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20fluid" title=" synovial fluid"> synovial fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=serum" title=" serum"> serum</a>, <a href="https://publications.waset.org/abstracts/search?q=dog" title=" dog"> dog</a> </p> <a href="https://publications.waset.org/abstracts/61004/evaluation-of-osteoprotegrin-opg-and-tumor-necrosis-factor-a-tnf-a-changes-in-synovial-fluid-and-serum-in-dogs-with-osteoarthritis-an-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61004.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">318</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">75</span> Isolation, Characterization and Myogenic Differentiation of Synovial Mesenchymal Stem Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Y.%20Meligy">Fatma Y.

Then to assess the potentiality of myogenic differentiation of these isolated MSCs. Methods: The MSCs were isolated from synovial membrane by digestion method. Three adult rats were used. The 5 -azacytidine was added to the cultured cells for one day. The isolated cells and treated cells are assessed using immunoflouresence, flowcytometry, PCR and real time PCR. Results: The isolated stem cells showed morphological aspect of stem cells they showed strong positivity to CD44 and CD90 in immunoflouresence while in CD34 and CD45 showed negative reaction. The treated cells with 5-azacytidine was shown to have positive reaction for desmin. Flowcytometric analysis showed that synovial MSCs had strong positive percentage for CD44(%98)and CD90 (%97) and low percentage for CD34 & CD45 while the treated cells showed positive percentage for myogenic marker myogenin (85%). As regard the PCR and Real time PCR, the treated cells showed positive reaction to the desmin primer. Conclusion: The adult MSCs were isolated successfully from synovial membrane and characterized with stem cell markers. The isolated cells could be differentiated in vitro into myogenic cells. These differentiated cells could be used in auto-replacement of diseased or traumatized muscle cells as a regenerative therapy for muscle disorders and trauma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mesenchymal%20stem%20cells" title="mesenchymal stem cells">mesenchymal stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20membrane" title=" synovial membrane"> synovial membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=myogenic%20differentiation" title=" myogenic differentiation "> myogenic differentiation </a> </p> <a href="https://publications.waset.org/abstracts/29107/isolation-characterization-and-myogenic-differentiation-of-synovial-mesenchymal-stem-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29107.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">306</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">74</span> Potential Role of IL-1β in Synovial Fluid in Modulating Multiple Joint Tissue Pathologies Leading to Inflammation and Accelerating Cartilage Degeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priya%20Kulkarni">Priya Kulkarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumya%20Koppikar"> Soumya Koppikar</a>, <a href="https://publications.waset.org/abstracts/search?q=Datta%20Shinde"> Datta Shinde</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Deshpande"> Shantanu Deshpande</a>, <a href="https://publications.waset.org/abstracts/search?q=Narendrakumar%20Wagh"> Narendrakumar Wagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhay%20Harsulkar"> Abhay Harsulkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoarthritis (OA) is associated with multiple and overlapping aetiologies. IL-1β is produced by stressed tissue and known to aggravate disease pathologies. We selected 10 patients with elevated IL-1β in their synovial fluids (SF). We hypothesized IL-1β as nodal-point connecting different pathologies. IL-1β was higher in all meniscal tear (MT) patients perhaps as the earliest response to injury. Since MT above age of 30 leads to OA in less than 5 years, it is attributed that IL-1β modulates OA pathology. Among all bilateral OA patients, an interesting case operated for Total-Knee-Replacement revealed differential cartilage degeneration demonstrating strong association with higher IL-1β. Symptoms like acute-pain, effusion and redness were correlated with higher IL-1β and NO (Nitric-oxide). However, higher IL-1β was also found without typical-inflammation characterized by infiltration of neutrophils and macrophages. Cultured synoviocytes responded to IL-1β by releasing NO. In conclusion, IL-1β in SF acquires central position influencing different OA pathologies and aetiologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IL-1%CE%B2" title="IL-1β">IL-1β</a>, <a href="https://publications.waset.org/abstracts/search?q=meniscal%20tear" title=" meniscal tear"> meniscal tear</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title=" osteoarthritis"> osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20fluid" title=" synovial fluid"> synovial fluid</a> </p> <a href="https://publications.waset.org/abstracts/6228/potential-role-of-il-1v-in-synovial-fluid-in-modulating-multiple-joint-tissue-pathologies-leading-to-inflammation-and-accelerating-cartilage-degeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6228.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">596</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">73</span> Localisation of Fluorescently Labelled Drug-Free Phospholipid Vesicles to the Cartilage Surface of Rat Synovial Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sam%20Yurdakul">Sam Yurdakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20Baverstock"> Nick Baverstock</a>, <a href="https://publications.waset.org/abstracts/search?q=Jim%20Mills"> Jim Mills</a> </p> <p class="card-text"><strong>Abstract:</strong></p> TDT 064 (FLEXISEQ®) is a drug-free gel used to treat osteoarthritis (OA)-associated pain and joint stiffness. It contains ultra-deformable phospholipid Sequessome™ vesicles, which can pass through the skin barrier intact. In six randomized OA studies, topical TDT 064 was well tolerated and improved joint pain, physical function and stiffness. In the largest study, these TDT 064-mediated effects were statistically significantly greater than oral placebo and equivalent to celecoxib. To understand the therapeutic effects of TDT 064, we investigated the localisation of the drug-free vesicles within rat synovial joints. TDT 064 containing DiO-labelled Sequessome™ vesicles was applied to the knees of four 6-week-old CD® hairless rats (10 mg/kg/ joint), 2–3 times/day, for 3 days (representing the recommended clinical dose). Eighteen hours later, the animals and one untreated control were sacrificed, and the knee joints isolated, flash frozen and embedded in Acrytol Mounting Media™. Approximately 15 sections (10 µm) from each joint were analysed by fluorescence microscopy. To investigate whether the localisation of DiO fluorescence was associated with intact vesicles, an anti-PEG monoclonal antibody (mAb) was used to detect Tween, a constituent of Sequessome™ vesicles. Sections were visualized at 484 nm (DiO) and 647 nm (anti-PEG mAb) and analysed using inForm 1.4 (Perkin Elmer, Inc.). Significant fluorescence was observed at 484 nm in sections from TDT 064-treated animals. No non-specific fluorescence was observed in control sections. Fluorescence was detected as discrete vesicles on the cartilage surfaces, inside the cartilaginous matrix and within the synovial space. The number of DiO-labelled vesicles in multiple fields of view was consistent and >100 in sections from four different treated knees. DiO and anti-PEG mAb co-localised within the collagenous tissues in four different joint sections. Under higher magnification (40x), vesicles were seen in the intercellular spaces of the synovial joint tissue, but no fluorescence was seen inside cells. These data suggest that the phospholipid vesicles in TDT 064 localize at the surface of the joint cartilage; these vesicles may therefore be supplementing the phospholipid deficiency reported in OA and acting as a biolubricant within the synovial joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20pain" title="joint pain">joint pain</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title=" osteoarthritis"> osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=phospholipid%20vesicles" title=" phospholipid vesicles"> phospholipid vesicles</a>, <a href="https://publications.waset.org/abstracts/search?q=TDT%20064" title=" TDT 064"> TDT 064</a> </p> <a href="https://publications.waset.org/abstracts/22741/localisation-of-fluorescently-labelled-drug-free-phospholipid-vesicles-to-the-cartilage-surface-of-rat-synovial-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22741.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">443</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">72</span> Microfluidic Lab on Chip Platform for the Detection of Arthritis Markers from Synovial Organ on Chip by Miniaturizing Enzyme-Linked ImmunoSorbent Assay Protocols</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Boschis">Laura Boschis</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20D.%20Ozzello"> Elena D.

In consonance with these arguments, we designed a study to measure morphological and functional echocardiographic variations early after transplantation. Method: The patients with normal renal function underwent two advanced echocardiographic studies to examine the structural and functional changes in left ventricular mass before and 3-month after transplantation. Results: From a total of 23 participants 21(91.3%) presented with left ventricular hypertrophy, 60.9% in eccentric and 30.4% in concentric group. Diastolic dysfunction improved in concentric group after transplantation. Both in pre and post transplantation global longitudinal strain (GLS)- average in eccentric group was more than concentric (-17.45 ± 2.75 vs -14.3 ± 3.38 p=0.03) and (-18.08 ± 2.6 vs -16.1 ± 2.7 p= 0.04) respectively. Conclusion: Improvement and recovery of left ventricular function in concentric group was better and sooner than eccentric after kidney transplantation. Although fractional shortening and diastolic function and GLS-4C in pre-transplantation in concentric group was worse than eccentric, but therapeutic response to kidney transplantation in concentric was more and earlier than eccentric group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20kidney%20disease" title="chronic kidney disease">chronic kidney disease</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20stage%20renal%20disease" title=" end stage renal disease"> end stage renal disease</a>, <a href="https://publications.waset.org/abstracts/search?q=left%20ventricular%20hypertrophy" title=" left ventricular hypertrophy"> left ventricular hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20longitudinal%20strain" title=" global longitudinal strain"> global longitudinal strain</a> </p> <a href="https://publications.waset.org/abstracts/184484/changing-left-ventricular-hypertrophy-after-kidney-transplantation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184484.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">70</span> Cretinism Muscular Hypertrophy: An Unorthodox Reflection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harim%20Mohsin">Harim Mohsin</a>, <a href="https://publications.waset.org/abstracts/search?q=Afshan%20Channa"> Afshan Channa</a>, <a href="https://publications.waset.org/abstracts/search?q=Beena%20Saad"> Beena Saad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Kocher Debre Semelaigne Syndrome (KDSS) is known as cretinism muscular hypertrophy. It is an unusual presentation in intellectually deficit children, commonly associated with congenital or iatrogenic hypothyroidism. The creatinine phosphokinase (CPK) is usually elevated and it’s commonly found in males, consanguineous marriage and ages 18 months to 10 years. It might be misdiagnosed without the classical features of hypothyroidism at first presentation. We present a case of 15 year old intellectually deficit female with epilepsy managed on phenytoin. She had rigidity, myxedema, calf muscle hypertrophy and agitation. The patient was managed as Neuroleptic Malignant Syndrome due to raised CPK of 40,680 IU/L and mixed presentation. Nevertheless, no improvement was noticed and thyroid profile was done to exclude alternative resources. Thyroid stimulating hormone (TSH) was 74.5 IU, Free T3 1.22 ng/dl, and Free T4 0.43 ng/dl. Thyroxine was started along with change in antiepileptic leading to recovery. This case report highlights the inconsistent finding of KDSS. The female gender, non-consanguineous marriage, delayed onset with primarily neuromuscular symptoms, and raised CPK is a rare demonstration in KDSS. Additionally, thyroid profile is not routinely done, which can lead to misdiagnosis and mismanagement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cretinism" title="cretinism">cretinism</a>, <a href="https://publications.waset.org/abstracts/search?q=hypothyroidism" title=" hypothyroidism"> hypothyroidism</a>, <a href="https://publications.waset.org/abstracts/search?q=intellectual%20deficit" title=" intellectual deficit"> intellectual deficit</a>, <a href="https://publications.waset.org/abstracts/search?q=KDSS" title=" KDSS"> KDSS</a> </p> <a href="https://publications.waset.org/abstracts/36833/cretinism-muscular-hypertrophy-an-unorthodox-reflection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36833.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">375</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">69</span> The Influence of Ecologically -Valid High- and Low-Volume Resistance Training on Muscle Strength and Size in Trained Men </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20Dellatolla">Jason Dellatolla</a>, <a href="https://publications.waset.org/abstracts/search?q=Scott%20Thomas"> Scott Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Much of the current literature pertaining to resistance training (RT) volume prescription lacks ecological validity, and very few studies investigate true high-volume ranges. Purpose: The present study sought to investigate the effects of ecologically-valid high- vs low-volume RT on muscular size and strength in trained men. Methods: This study systematically randomized trained, college-aged men into two groups: low-volume (LV; n = 4) and high-volume (HV; n = 5). The sample size was affected by COVID-19 limitations. Subjects followed an ecologically-valid 6-week RT program targeting both muscle size and strength. RT occurred 3x/week on non-consecutive days. Over the course of six weeks, LVR and HVR gradually progressed from 15 to 23 sets/week and 30 to 46 sets/week of lower-body RT, respectively. Muscle strength was assessed via 3RM tests in the squat, stiff-leg deadlift (SL DL), and leg press. Muscle hypertrophy was evaluated through a combination of DXA, BodPod, and ultrasound (US) measurements. Results: Two-way repeated-measures ANOVAs indicated that strength in all 3 compound lifts increased significantly among both groups (p < 0.01); between-group differences only occurred in the squat (p = 0.02) and SL DL (p = 0.03), both of which favored HVR. Significant pre-to-post-study increases in indicators of hypertrophy were discovered for lean body mass in the legs via DXA, overall fat-free mass via BodPod, and US measures of muscle thickness (MT) for the rectus femoris, vastus intermedius, vastus medialis, vastus lateralis, long-head of the biceps femoris, and total MT. Between-group differences were only found for MT of the vastus medialis – favoring HVR. Moreover, each additional weekly set of lower-body RT was associated with an average increase in MT of 0.39% in the thigh muscles. Conclusion: We conclude that ecologically-valid RT regimens significantly improve muscular strength and indicators of hypertrophy. When HVR is compared to LVR, HVR provides significantly greater gains in muscular strength but has no greater effect on hypertrophy over the course of 6 weeks in trained, college-aged men. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20validity" title="ecological validity">ecological validity</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophy" title=" hypertrophy"> hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance%20training" title=" resistance training"> resistance training</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength "> strength </a> </p> <a href="https://publications.waset.org/abstracts/130631/the-influence-of-ecologically-valid-high-and-low-volume-resistance-training-on-muscle-strength-and-size-in-trained-men" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130631.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">114</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">68</span> Liver Regeneration of Small in situ Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ziwei%20Song">Ziwei Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Junjun%20Fan"> Junjun Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeremy%20Teo"> Jeremy Teo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Yu"> Yang Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yukun%20Ma"> Yukun Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Yan"> Jie Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shupei%20Mo"> Shupei Mo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Tucker-Kellogg"> Lisa Tucker-Kellogg</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20So"> Peter So</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanry%20Yu"> Hanry Yu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Liver is the center of detoxification and exposed to toxic metabolites all the time. It is highly regenerative after injury, with the ability to restore even after 70% partial hepatectomy. Most of the previous studies were using hepatectomy as injury models for liver regeneration study. There is limited understanding of small-scale liver injury, which can be caused by either low dose drug consumption or hepatocyte routine metabolism. Although these small in situ injuries do not cause immediate symptoms, repeated injuries will lead to aberrant wound healing in liver. Therefore, the cellular dynamics during liver regeneration is critical for our understanding of liver regeneration mechanism. We aim to study the liver regeneration of small-scale in situ liver injury in transgenic mice labeling actin (Lifeact-GFP). Previous studies have been using sample sections and biopsies of liver, which lack real-time information. In order to trace every individual hepatocyte during the regeneration process, we have developed and optimized an intravital imaging system that allows in vivo imaging of mouse liver for consecutive 5 days, allowing real-time cellular tracking and quantification of hepatocytes. We used femtosecond-laser ablation to make controlled and repeatable liver injury model, which mimics the real-life small in situ liver injury. This injury model is the first case of its kind for in vivo study on liver. We found that small-scale in situ liver injury is repaired by the coordination of hypertrophy and migration of hepatocytes. Hypertrophy is only transient at initial phase, while migration is the main driving force to complete the regeneration process. From cellular aspect, Akt/mTOR pathway is activated immediately after injury, which leads to transient hepatocyte hypertrophy. From mechano-sensing aspect, the actin cable, formed at apical surface of wound proximal hepatocytes, provides mechanical tension for hepatocyte migration. This study provides important information on both chemical and mechanical signals that promote liver regeneration of small in situ injury. We conclude that hypertrophy and migration play a dominant role at different stages of liver regeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatocyte" title="hepatocyte">hepatocyte</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophy" title=" hypertrophy"> hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=intravital%20imaging" title=" intravital imaging"> intravital imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20regeneration" title=" liver regeneration"> liver regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a> </p> <a href="https://publications.waset.org/abstracts/77939/liver-regeneration-of-small-in-situ-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77939.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">205</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">67</span> Cardiothoracic Ratio in Postmortem Computed Tomography: A Tool for the Diagnosis of Cardiomegaly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alex%20Eldo%20Simon">Alex Eldo Simon</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhishek%20Yadav"> Abhishek Yadav</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to evaluate the utility of postmortem computed tomography (CT) and heart weight measurements in the assessment of cardiomegaly in cases of sudden death due to cardiac origin by comparing the results of these two diagnostic methods. The study retrospectively analyzed postmortem computed tomography (PMCT) data from 54 cases of sudden natural death and compared the findings with those of the autopsy. The study involved measuring the cardiothoracic ratio (CTR) from coronal computed tomography (CT) images and determining the actual cardiac weight by weighing the heart during the autopsy. The inclusion criteria for the study were cases of sudden death suspected to be caused by cardiac pathology, while exclusion criteria included death due to unnatural causes such as trauma or poisoning, diagnosed natural causes of death related to organs other than the heart, and cases of decomposition. Sensitivity, specificity, and diagnostic accuracy were calculated, and to evaluate the accuracy of using the cardiothoracic ratio (CTR) to detect an enlarged heart, the study generated receiver operating characteristic (ROC) curves. The cardiothoracic ratio (CTR) is a radiological tool used to assess cardiomegaly by measuring the maximum cardiac diameter in relation to the maximum transverse diameter of the chest wall. The clinically used criteria for CTR have been modified from 0.50 to 0.57 for use in postmortem settings, where abnormalities can be detected by comparing CTR values to this threshold. A CTR value of 0.57 or higher is suggestive of hypertrophy but not conclusive. Similarly, heart weight is measured during the traditional autopsy, and a cardiac weight greater than 450 grams is defined as hypertrophy. Of the 54 cases evaluated, 22 (40.7%) had a cardiothoracic ratio (CTR) ranging from > 0.50 to equal 0.57, and 12 cases (22.2%) had a CTR greater than 0.57, which was defined as hypertrophy. The mean CTR was calculated as 0.52 ± 0.06. Among the 54 cases evaluated, the weight of the heart was measured, and the mean was calculated as 369.4 ± 99.9 grams. Out of the 54 cases evaluated, 12 were found to have hypertrophy as defined by PMCT, while only 9 cases were identified with hypertrophy in traditional autopsy. The sensitivity and specificity of the test were calculated as 55.56% and 84.44%, respectively. The sensitivity of the hypertrophy test was found to be 55.56% (95% CI: 26.66, 81.12¹), the specificity was 84.44% (95% CI: 71.22, 92.25¹), and the diagnostic accuracy was 79.63% (95% CI: 67.1, 88.23¹). The limitation of the study was a low sample size of only 54 cases, which may limit the generalizability of the findings. The comparison of the cardiothoracic ratio with heart weight in this study suggests that PMCT may serve as a screening tool for medico-legal autopsies when performed by forensic pathologists. However, it should be noted that the low sensitivity of the test (55.5%) may limit its diagnostic accuracy, and therefore, further studies with larger sample sizes and more diverse populations are needed to validate these findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PMCT" title="PMCT">PMCT</a>, <a href="https://publications.waset.org/abstracts/search?q=virtopsy" title=" virtopsy"> virtopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=CTR" title=" CTR"> CTR</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiothoracic%20ratio" title=" cardiothoracic ratio"> cardiothoracic ratio</a> </p> <a href="https://publications.waset.org/abstracts/164730/cardiothoracic-ratio-in-postmortem-computed-tomography-a-tool-for-the-diagnosis-of-cardiomegaly" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164730.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">81</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">66</span> Cardiac Hypertrophy in Diabetes; The Role of Factor Forkhead Box Class O-Regulation by O-GlcNAcylation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadjavad%20Sotoudeheian">Mohammadjavad Sotoudeheian</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Farahmandian"> Navid Farahmandian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cardiac hypertrophy arises in response to persistent increases in hemodynamic loads. In comparison, diabetic cardiomyopathy is defined by an abnormal myocardial changes without other cardiac-related risk factors. Pathological cardiac hypertrophy and myocardial remodeling are hallmarks of cardiovascular diseases and are risk factors for heart failure. The transcription factor forkhead box class O (FOXOs) can protect heart tissue by hostile oxidative stress and stimulating apoptosis and autophagy. FOXO proteins, as sensitive elements and mediators in response to environmental changes, have been revealed to prevent and inverse cardiac hypertrophy. FOXOs are inhibited by insulin and are critical mediators of insulin action. Insulin deficiency and uncontrolled diabetes lead to a catabolic state. FOXO1 acts downstream of the insulin-dependent pathways, which are dysregulated in diabetes. It regulates cardiomyocyte hypertrophy downstream of IGF1R/PI3K/Akt activation, which are critical regulators of cardiac hypertrophy. The complex network of signaling pathways comprising insulin/IGF-1 signaling, AMPK, JNK, and Sirtuins regulate the development of cardiovascular dysfunction by modulating the activity of FOXOs. Insulin receptors and IGF1R act via the PI3k/Akt and the MAPK/ERK pathways. Activation of Akt in response to insulin or IGF-1 induces phosphorylation of FOXOs. Increased protein synthesis induced by activation of the IGF-I/Akt/mTOR signaling pathway leads to hypertrophy. This pathway and the myostatin/Smad pathway are potent negative muscle development regulators. In cardiac muscle, insulin receptor substrates (IRS)-1 or IRS-2 activates the Akt signaling pathway and inactivate FOXO1. Under metabolic stress, p38 MAPK promotes degradation of IRS-1 and IRS-2 in cardiac myocytes and activates FOXO1, leading to cardiomyopathy. Sirt1 and FOXO1 interaction play an essential role in starvation-induced autophagy in cardiac metabolism. Inhibition of Angiotensin-II induced cardiomyocyte hypertrophy is associated with reduced FOXO1 acetylation and activation of Sirt1. The NF-κB, ERK, and FOXOs are de-acetylated by SIRT1. De-acetylation of FOXO1 induces the expression of genes involved in autophagy and stimulates autophagy flux. Therefore, under metabolic stress, FOXO1 can cause diabetic cardiomyopathy. The overexpression of FOXO1 leads to decreased cardiomyocyte size and suppresses cardiac hypertrophy through inhibition of the calcineurin–NFAT pathway. Diabetes mellitus is associated with elevation of O-GlcNAcylation. Some of its binding partners regulate the substrate selectivity of O-GlcNAc transferase (OGT). O-GlcNAcylation of essential contractile proteins may inhibit protein-protein interactions, reduce calcium sensitivity, and modulate contractile function. Uridine diphosphate (UDP)-GlcNAc is the obligatory substrate of OGT, which catalyzes a reversible post-translational protein modification. The increase of O-GlcNAcylation is accompanied by impaired cardiac hypertrophy in diabetic hearts. Inhibition of O-GlcNAcylation blocks activation of ERK1/2 and hypertrophic growth. O-GlcNAc modification on NFAT is required for its translocation from the cytosol to the nucleus, where NFAT stimulates the transcription of various hypertrophic genes. Inhibition of O-GlcNAcylation dampens NFAT-induced cardiac hypertrophic growth. Transcriptional activity of FOXO1 is enriched by improved O-GlcNAcylation upon high glucose stimulation or OGT overexpression. In diabetic conditions, the modification of FOXO1 by O-GlcNAc is promoted in cardiac troponin I and myosin light chain 2. Therefore targeting O-GlcNAcylation represents a potential therapeutic option to prevent hypertrophy in the diabetic heart. <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=cardiac%20hypertrophy" title=" cardiac hypertrophy"> cardiac hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=O-GlcNAcylation" title=" O-GlcNAcylation"> O-GlcNAcylation</a>, <a href="https://publications.waset.org/abstracts/search?q=FOXO1" title=" FOXO1"> FOXO1</a>, <a href="https://publications.waset.org/abstracts/search?q=Akt" title=" Akt"> Akt</a>, <a href="https://publications.waset.org/abstracts/search?q=PI3K" title=" PI3K"> PI3K</a>, <a href="https://publications.waset.org/abstracts/search?q=AMPK" title=" AMPK"> AMPK</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin" title=" insulin"> insulin</a> </p> <a href="https://publications.waset.org/abstracts/151200/cardiac-hypertrophy-in-diabetes-the-role-of-factor-forkhead-box-class-o-regulation-by-o-glcnacylation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151200.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">108</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">65</span> Antioxidant Status in Synovial Fluid from Osteoarthritis Patients: A Pilot Study in Indian Demography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Koppikar">S.

Oxidative stress is known to instigate classical stress factors such as cytokines, chemokines and ROS, which hampers cartilage remodelling process and ultimately results in worsening the disease. Synovial fluid (SF) is a biological communicator between cartilage and synovium that accumulates redox and biochemical signalling mediators. The present work attempts to measure several oxidative stress markers in the synovial fluid obtained from knee OA patients with varying degree of disease severity. Thirty OA and five Meniscal-tear (MT) patients were graded using Kellgren-Lawrence scale and assessed for Nitric oxide (NO), Nitrate-Nitrite (NN), 2,2-diphenyl-1-picrylhydrazyl (DPPH), Ferric Reducing Antioxidant Potential (FRAP), Catalase (CAT), Superoxide dismutase (SOD) and Malondialdehyde (MDA) levels for comparison. Out of various oxidative markers studied, NO and SOD showed significant difference between moderate and severe OA (p= 0.007 and p= 0.08, respectively), whereas CAT demonstrated significant difference between MT and mild group (p= 0.07). Interestingly, NN revealed statistically positive correlation with OA severity (p= 0.001 and p= 0.003). MDA, a lipid peroxidation by-product was estimated maximum in early OA when compared to MT (p= 0.06). However, FRAP did not show any correlation with OA severity or MT control. NO is an essential bio-regulatory molecule essential for several physiological processes, and inflammatory conditions. However, due to its short life, exact estimation of NO becomes difficult. NO and its measurable stable products are still it is considered as one of the important biomarker of oxidative damage. Levels of NO and nitrite-nitrate in SF of patients with OA indicated its involvement in the disease progression. When SF groups were compared, a significant correlation among moderate, mild and MT groups was established. To summarize, present data illustrated higher levels of NO, SOD, CAT, DPPH and MDA in early OA in comparison with MT, as a control group. NN had emerged as a prognostic bio marker in knee OA patients, which may act as futuristic targets in OA treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=knee%20osteoarthritis" title=" knee osteoarthritis"> knee osteoarthritis</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=synovial%20fluid" title=" synovial fluid"> synovial fluid</a> </p> <a href="https://publications.waset.org/abstracts/21280/antioxidant-status-in-synovial-fluid-from-osteoarthritis-patients-a-pilot-study-in-indian-demography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21280.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">477</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">64</span> Alcohol Septal Ablation in a 19-Year-Old with Hypertrophic Obstructive Cardiomyopathy Patient: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christine%20Ysabelle%20G.%20Roman">Christine Ysabelle G.

It is a genetically determined heart disease characterized by significant myocardium hypertrophy that results in diastolic dysfunction, left ventricular outflow tract obstruction, and an increased risk of arrhythmias. The primary treatment in patients with such conditions is negative inotropic drugs, such as beta-blockers, calcium channel antagonists, and disopyramide. However, for those who remain symptomatic and need septal reduction therapy, surgical septal myectomy or alcohol septal ablation are options. Case Summary: A 19 – year old female presented in the authors’ institution with easy fatigability. The consult was done a year prior, and 2D echocardiography was requested which showed concentric left ventricular hypertrophy, asymmetrically hypertrophied interventricular septum (IVS) with the largest diameter of 3.3cm & subaortic dynamic obstruction with a maximum gradient of 47 mmHg. A repeat echo a year later showed asymmetric septal hypertrophy (IVS measuring at 3cm) with the systolic anterior motion of anterior mitral valve leaflet and left ventricular outflow tract obstruction (peak gradient of 50mmHg). The patient then underwent alcohol septal ablation and was discharged stable after four days of admission. Conclusion: Hypertrophic obstructive cardiomyopathy, a cardiovascular genetic disease, results in various patterns of left ventricular hypertrophy and abnormality of mitral valve apparatus. The patient is managed medically initially. However, despite optimal drug therapy and significant left ventricular outflow tract obstruction, significant heart failure symptoms or syncope require invasive treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypertrophic%20obstructive%20cardiomyopathy" title="hypertrophic obstructive cardiomyopathy">hypertrophic obstructive cardiomyopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=left%20ventricular%20outflow%20tract%20obstruction" title=" left ventricular outflow tract obstruction"> left ventricular outflow tract obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=alcohol%20septal%20ablation" title=" alcohol septal ablation"> alcohol septal ablation</a>, <a href="https://publications.waset.org/abstracts/search?q=alcohol" title=" alcohol"> alcohol</a> </p> <a href="https://publications.waset.org/abstracts/152816/alcohol-septal-ablation-in-a-19-year-old-with-hypertrophic-obstructive-cardiomyopathy-patient-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152816.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">80</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">63</span> The Role of Autophagy Modulation in Angiotensin-II Induced Hypertrophy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kitti%20Szoke">Kitti Szoke</a>, <a href="https://publications.waset.org/abstracts/search?q=Laszlo%20Szoke"> Laszlo Szoke</a>, <a href="https://publications.waset.org/abstracts/search?q=Attila%20Czompa"> Attila Czompa</a>, <a href="https://publications.waset.org/abstracts/search?q=Arpad%20Tosaki"> Arpad Tosaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Istvan%20Lekli"> Istvan Lekli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autophagy plays an important role in cardiac hypertrophy, which is one of the most common causes of heart failure in the world. This self-degradative catabolic process, responsible for protein quality control, balancing sources of energy at critical times, and elimination of damaged organelles. The autophagic activity can be triggered by starvation, oxidative stress, or pharmacological agents, like rapamycin. This induced autophagy can promote cell survival during starvation or pathological stress. In this study, it is investigated the effect of the induced autophagic process on angiotensin induced hypertrophic H9c2 cells. In our study, it is used H9c2 cells as an in vitro model. To induce hypertrophy, cells were treated with 10000 nM angiotensin-II, and to activate autophagy, 100 nM rapamycin treatment was used. The following groups were formed: 1: control, 2: 10000 nM AT-II, 3: 100 nM rapamycin, 4: 100 nM rapamycin pretreatment then 10000 nM AT-II. The cell viability was examined via MTT (cell proliferation assay) assay. The cells were stained with rhodamine-conjugated phalloidin and DAPI to visualize F-actin filaments and cell nuclei then the cell size alteration was examined in a fluorescence microscope. Furthermore, the expression levels of autophagic and apoptotic proteins such as Beclin-1, p62, LC3B-II, Cleaved Caspase-3 were evaluated by Western blot. MTT assay result suggests that the used pharmaceutical agents in the tested concentrations did not have a toxic effect; however, at group 3, a slight decrement was detected in cell viability. In response to AT-II treatment, a significant increase was detected in the cell size; cells became hypertrophic. However, rapamycin pretreatment slightly reduced the cell size compared to group 2. Western blot results showed that AT-II treatment-induced autophagy, because the increased expression of Beclin-1, p62, LC3B-II were observed. However, due to the incomplete autophagy, the apoptotic Cleaved Caspase-3 expression also increased. Rapamycin pretreatment up-regulated Beclin-1 and LC3B-II, down-regulated p62 and Cleaved Caspase-3, indicating that rapamycin-induced autophagy can restore the normal autophagic flux. Taken together, our results suggest that rapamycin activated autophagy reduces angiotensin-II induced hypertrophy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angiotensin-II" title="angiotensin-II">angiotensin-II</a>, <a href="https://publications.waset.org/abstracts/search?q=autophagy" title=" autophagy"> autophagy</a>, <a href="https://publications.waset.org/abstracts/search?q=H9c2%20cell%20line" title=" H9c2 cell line"> H9c2 cell line</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophy" title=" hypertrophy"> hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=rapamycin" title=" rapamycin "> rapamycin </a> </p> <a href="https://publications.waset.org/abstracts/119861/the-role-of-autophagy-modulation-in-angiotensin-ii-induced-hypertrophy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119861.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">147</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">62</span> Traumatic Osteoarthritis Induces Mechanical Hyperalgesia through IL-1β/TNF-α-Mediated Upregulation of the Sema4D Gene Expression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hsiao-Chien%20Tsai">Hsiao-Chien Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Pin%20Chen"> Yu-Pin Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruei-Ming%20Chen"> Ruei-Ming Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Osteoarthritis (OA) is characterized by joint destruction and causes chronic disability. One of the prominent symptoms is pain. Alleviating the pain is necessary and urgent for the therapy of OA patients. However, currently, understanding the mechanisms that drive OA-induced pain remains challenging, which hampers the optimistic management of pain in OA patients. Semaphorin 4D (Sema4D) participates in axon guidance pathway and bone remodeling, thus, may play a role in the regulation of pain in OA. In this study, we have established a rat model of OA to find out the mechanisms of OA-induced pain and to deliberate the roles of Sema4D. Methods: Behavioral changes and the pro-inflammatory cytokines (IL-1β, TNF-α, and IL-17) associated with pain were measured during the development of OA. Sema4D expression in cartilage and synovial membrane at 1, 4, and 12 weeks after inducing OA was analyzed. To assess if Sema4D is related to the neurogenesis in OA as an axon repellant, we analyzed the expression of PGP9.5 as well. Results: Synovitis and cartilage degradation were evident histologically during the development of OA. Mechanical hyperalgesia was most severe at week 1, then persisted thereafter. It was associated with stress coping strategies. Similar to the pain behavioral results, levels of IL-1β and TNF-α in synovial lavage fluid were significantly elevated in the OA group at weeks 1 and 4, respectively. Sema4D expression in cartilage and the synovial membrane was also enhanced in the OA group and was correlated with pain and pro-inflammatory cytokines. The marker of neurogenesis, PGP9.5, was also enhanced during the development of OA. Discussion: OA induced mechanical hyperalgesia, which might be through upregulating IL-1β/TNF-α-mediated Sema4D expressions. If anti-Sema4D treatment could reduce OA-induced mechanical hyperalgesia and prevent the subsequent progression of OA needs to be further investigated. Significance: OA can induce mechanical hyperalgesia through upregulation of IL-1β/TNF-α-mediated Sema4D and PGP9.5 expressions. And the upregulation of Sema4D may indicate the severity or active status of OA and OA-induced pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traumatic%20osteoarthritis" title="traumatic osteoarthritis">traumatic osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20hyperalgesia" title=" mechanical hyperalgesia"> mechanical hyperalgesia</a>, <a href="https://publications.waset.org/abstracts/search?q=Sema4D" title=" Sema4D"> Sema4D</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20cytokines" title=" inflammatory cytokines"> inflammatory cytokines</a> </p> <a href="https://publications.waset.org/abstracts/161254/traumatic-osteoarthritis-induces-mechanical-hyperalgesia-through-il-1vtnf-a-mediated-upregulation-of-the-sema4d-gene-expression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161254.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">61</span> Acute Neurophysiological Responses to Resistance Training; Evidence of a Shortened Super Compensation Cycle and Early Neural Adaptations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Latella">Christopher Latella</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashlee%20M.%20Hendy"> Ashlee M.

Understanding neural responses from an acute resistance training session is pivotal in the prescription of frequency, intensity and volume in applied strength and conditioning practice. Therefore the primary aim of this study was to investigate the time course of neurophysiological mechanisms post training against current super compensation theory, and secondly, to examine whether these responses reflect neural adaptations observed with resistance training interventions. Methods: Participants (N=14) completed a randomised, counterbalanced crossover study comparing; control, strength and hypertrophy conditions. The strength condition involved 3 x 5RM leg extensions with 3min recovery, while the hypertrophy condition involved 3 x 12 RM with 60s recovery. Transcranial magnetic stimulation (TMS) and peripheral nerve stimulation were used to measure excitability of the central and peripheral neural pathways, and maximal voluntary contraction (MVC) to quantify strength changes. Measures were taken pre, immediately post, 10, 20 and 30 mins and 1, 2, 6, 24, 48, 72 and 96 hrs following training. Results: Significant decreases were observed at post, 10, 20, 30 min, 1 and 2 hrs for both training groups compared to control group for force, (p <.05), maximal compound wave; (p < .005), silent period; (p < .05). A significant increase in corticospinal excitability; (p < .005) was observed for both groups. Corticospinal excitability between strength and hypertrophy groups was near significance, with a large effect (η2= .202). All measures returned to baseline within 6 hrs post training. Discussion: Neurophysiological mechanisms appear to be significantly altered in the period 2 hrs post training, returning to homeostasis by 6 hrs. The evidence suggests that the time course of neural recovery post resistance training occurs 18-40 hours shorter than previous super compensation models. Strength and hypertrophy protocols showed similar response profiles with current findings suggesting greater post training corticospinal drive from hypertrophy training, despite previous evidence that strength training requires greater neural input. The increase in corticospinal drive and decrease inl inhibition appear to be a compensatory mechanism for decreases in peripheral nerve excitability and maximal voluntary force output. The changes in corticospinal excitability and inhibition are akin to adaptive processes observed with training interventions of 4 wks or longer. It appears that the 2 hr recovery period post training is the most influential for priming further neural adaptations with resistance training. Secondly, the frequency of prescribed resistance sessions can be scheduled closer than previous super compensation theory for optimal strength gains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neural%20responses" title="neural responses">neural responses</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance%20training" title=" resistance training"> resistance training</a>, <a href="https://publications.waset.org/abstracts/search?q=super%20compensation" title=" super compensation"> super compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=transcranial%20magnetic%20stimulation" title=" transcranial magnetic stimulation"> transcranial magnetic stimulation</a> </p> <a href="https://publications.waset.org/abstracts/48649/acute-neurophysiological-responses-to-resistance-training-evidence-of-a-shortened-super-compensation-cycle-and-early-neural-adaptations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48649.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">283</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">60</span> The Existence of a Sciatic Artery in Congenital Lower Limb Deformities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waseem%20Al%20Talalwah">Waseem Al Talalwah</a>, <a href="https://publications.waset.org/abstracts/search?q=Shorok%20Al%20Dorazi"> Shorok Al Dorazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Roger%20Soames"> Roger Soames</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Persistent sciatic artery is a rare anatomical vascular variation resulting from a lack of regression of the embryonic dorsal axial artery.

Metabolic alterations may be a role in osteoarthritis (OA) pathogenesis, and these changes influence joint destruction via several cytokine. Especially, in OA patients, levels of IL-1β are elevated in the synovial fluid, synovial membrane, subchondral bone, and cartilage. The IL-1β is activated by NLRP3 inflammasomes, and NLRP3 inflammasomes are cytosolic complexes that drive the production of other inflammatory cytokines, including IL-1β. In this study, we examined that SIRT1 suppresses IL-1β through inhibiting NLRP3 inflammasomes and SIRT1 ameliorates osteoarthritis. OA fibroblasts were isolated from synovium of OA patients. IL-1β and NLRP3 were detected in synovium of OA patients by immunohistochemistry. Lipopolysaccharides (LPS) stimulated the expression of active IL-1β mRNA in OA fibroblasts and combination of LPS, and adenosine triphosphate increased more the expression of active IL-1β in OA fibroblasts. The level of IL-1β was measured by western blot and ELISA assay. NLRP3 inflammasomes complex were measured by western blot. SIRT1 did not inhibit expression of NLRP3 inflammasome. So caspase-1, apoptotic speck-like protein containing a caspase recruitment domain (ASC) and NLRP3 protein were expressed in OA fibroblasts. But SIRT1 suppressed activation of IL-1β by inhibiting activity of caspase-1 via NLRP3 inflammasome in OA fibroblasts under LPS plus ATP stimulation. These results suggest that SIRT1 is a modulator of NLRP3 inflammasomes in OA fibroblasts and ameliorate IL-1β, so expression of SIRT1 in OA fibroblast may be a potential strategy for OA inflammation treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title="osteoarthritis">osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammasome" title=" inflammasome"> inflammasome</a>, <a href="https://publications.waset.org/abstracts/search?q=SIRT1" title=" SIRT1"> SIRT1</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-1beta" title=" IL-1beta"> IL-1beta</a> </p> <a href="https://publications.waset.org/abstracts/76630/the-effect-of-sirt1-on-nlrp3-nucleotide-oligomerization-domain-like-receptor-family-pyrin-domain-containing-3-inflammasome-of-osteoarthritis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76630.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">199</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">58</span> Gender Features of Left Ventricular Myocardial Remodeling and the Development of Chronic Heart Failure in Patients with Postinfarction Cardiosclerosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Dadashova">G.

Material and methods: The study included 112 patients of both sexes; aged 45 to 60 years with postinfarction cardiosclerosis had functional class (FC) heart failure II-IV of NYHA which were examined on the basis of Azerbaijan Scientific Research Institute of Cardiology. The patients were divided into 2 groups: 1st c. 60 males, mean age 54,8 ± 3,3 years, and 2nd gr 52 women, mean age 55,8 ± 3,1 years. To assess cardiac hemodynamic all patients underwent echocardiography (B-M-modes) using ‘Vivid 3’. Thus on the basis of indicators such as the index of the relative thickness of the left ventricle wall and the index of left ventricular mass (LVMI) was identified the architectonic model of the left ventricle. Results: According to our research leading cause of heart failure in women is 50.5% of cases of hypertension, ischemic heart disease 23.7% (with 79.5% of the cases developed in patients with chronic heart failure who did not have a history of myocardial infarction). While in men is the undisputed leader of CHD, forming 78.3% of CHF (80.3% in men with CHF occurred after myocardial infarction). According to our research in women more often than men CHF develops a type of diastolic dysfunction (DD, and left ventricular ejection fraction remained unchanged. Since DD occurs in men at 65,8% vs. 76,4% of women when p < 0,05. In the group of women was more common prognostic neblagopryatnye remodeling - eccentric hypertrophy of the left ventricle: 68% vs. 54.5% among men (p < 0,05), concentric left ventricular hypertrophy: 21% in women vs 19,1% (p > 0,05 ). Conclusions: Patients with heart failure are a number of gender-specific: the prevalence of hypertension in women, and coronary heart disease in men. While in women with heart failure often recorded diastolic dysfunction and characterized by the development of prognostically unfavorable remodeling types: eccentric and concentric LV hypertrophy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chronic%20heart%20failure" title="chronic heart failure">chronic heart failure</a>, <a href="https://publications.waset.org/abstracts/search?q=arterial%20hypertension" title=" arterial hypertension"> arterial hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=remodeling" title=" remodeling"> remodeling</a>, <a href="https://publications.waset.org/abstracts/search?q=diastolic%20dysfunction" title=" diastolic dysfunction"> diastolic dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=men" title=" men"> men</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemic%20heart%20disease" title=" ischemic heart disease"> ischemic heart disease</a> </p> <a href="https://publications.waset.org/abstracts/25834/gender-features-of-left-ventricular-myocardial-remodeling-and-the-development-of-chronic-heart-failure-in-patients-with-postinfarction-cardiosclerosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25834.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">348</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">57</span> Glycosaminoglycan, a Cartilage Erosion Marker in Synovial Fluid of Osteoarthritis Patients Strongly Correlates with WOMAC Function Subscale</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priya%20Kulkarni">Priya Kulkarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumya%20Koppikar"> Soumya Koppikar</a>, <a href="https://publications.waset.org/abstracts/search?q=Narendrakumar%20Wagh"> Narendrakumar Wagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhanshri%20Ingle"> Dhanshri Ingle</a>, <a href="https://publications.waset.org/abstracts/search?q=Onkar%20Lande"> Onkar Lande</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhay%20Harsulkar">Abhay Harsulkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cartilage is an extracellular matrix composed of aggrecan, which imparts it with a great tensile strength, stiffness and resilience. Disruption in cartilage metabolism leading to progressive degeneration is a characteristic feature of Osteoarthritis (OA). The process involves enzymatic depolymerisation of cartilage specific proteoglycan, releasing free glycosaminoglycan (GAG). This released GAG in synovial fluid (SF) of knee joint serves as a direct measure of cartilage loss, however, limited due to its invasive nature. Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used for assessing pain, stiffness and physical-functions in OA patients. The scale is comprised of three subscales namely, pain, stiffness and physical-function, intends to measure patient’s perspective of disease severity as well as efficacy of prescribed treatment. Twenty SF samples obtained from OA patients were analysed for their GAG values in SF using DMMB based assay. LK 1.0 vernacular version was used to attain WOMAC scale. The results were evaluated using SAS University software (Edition 1.0) for statistical significance. All OA patients revealed higher GAG values compared to the control value of 78.4±30.1µg/ml (obtained from our non-OA patients). Average WOMAC calculated was 51.3 while pain, stiffness and function estimated were 9.7, 3.9 and 37.7, respectively. Interestingly, a strong statistical correlation was established between WOMAC function subscale and GAG (p = 0.0102). This subscale is based on day-to-day activities like stair-use, bending, walking, getting in/out of car, rising from bed. However, pain and stiffness subscale did not show correlation with any of the studied markers and endorsed the atypical inflammation in OA pathology. On one side, where knee pain showed poor correlation with GAG, it is often noted that radiography is insensitive to cartilage degenerative changes; thus OA remains undiagnosed for long. Moreover, active cartilage degradation phase remains elusive to both, patient and clinician. Through analysis of large number of OA patients we have established a close association of Kellgren-Lawrence grades and increased cartilage loss. A direct attempt to correlate WOMAC and radiographic progression of OA with various biomarkers has not been attempted so far. We found a good correlation in GAG levels in SF and the function subscale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cartilage" title="cartilage">cartilage</a>, <a href="https://publications.waset.org/abstracts/search?q=Glycosaminoglycan" title=" Glycosaminoglycan"> Glycosaminoglycan</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20fluid" title=" synovial fluid"> synovial fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20ontario%20and%20McMaster%20Universities%20Arthritis%20Index" title=" western ontario and McMaster Universities Arthritis Index"> western ontario and McMaster Universities Arthritis Index</a> </p> <a href="https://publications.waset.org/abstracts/21197/glycosaminoglycan-a-cartilage-erosion-marker-in-synovial-fluid-of-osteoarthritis-patients-strongly-correlates-with-womac-function-subscale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21197.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">446</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">56</span> Magnetic Resonance Imaging for Assessment of the Quadriceps Tendon Cross-Sectional Area as an Adjunctive Diagnostic Parameter in Patients with Patellofemoral Pain Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jae%20Ni%20Jang">Jae Ni Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=SoYoon%20Park"> SoYoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukhee%20Park"> Sukhee Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Yumin%20Song"> Yumin Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Won%20Kim"> Jae Won Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Keum%20Nae%20Kang"> Keum Nae Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Uk%20Kim"> Young Uk Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: Patellofemoral pain syndrome (PFPS) is a common clinical condition characterized by anterior knee pain. Here, we investigated the quadriceps tendon cross-sectional area (QTCSA) as a novel predictor for the diagnosis of PFPS. By examining the association between the QTCSA and PFPS, we aimed to provide a more valuable diagnostic parameter and more equivocal assessment of the diagnostic potential of PFPS by comparing the QTCSA with the quadriceps tendon thickness (QTT), a traditional measure of quadriceps tendon hypertrophy. Patients and Methods: This retrospective study included 30 patients with PFPS and 30 healthy participants who underwent knee magnetic resonance imaging. T1-weighted turbo spin echo transverse magnetic resonance images were obtained. The QTCSA was measured on the axial-angled phases of the images by drawing outlines, and the QTT was measured at the most hypertrophied quadriceps tendon. Results: The average QTT and QTCSA for patients with PFPS (6.33±0.80 mm and 155.77±36.60 mm², respectively) were significantly greater than those for healthy participants (5.77±0.36 mm and 111.90±24.10 mm2, respectively; both P<0.001). We used a receiver operating characteristic curve to confirm the sensitivities and specificities for both the QTT and QTCSA as predictors of PFPS. The optimal diagnostic cutoff value for QTT was 5.98 mm, with a sensitivity of 66.7%, a specificity of 70.0%, and an area under the curve of 0.75 (0.62–0.88). The optimal diagnostic cutoff value for QTCSA was 121.04 mm², with a sensitivity of 73.3%, a specificity of 70.0%, and an area under the curve of 0.83 (0.74–0.93). Conclusion: The QTCSA was found to be a more reliable diagnostic indicator for PFPS than QTT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patellofemoral%20pain%20syndrome" title="patellofemoral pain syndrome">patellofemoral pain syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=quadriceps%20muscle" title=" quadriceps muscle"> quadriceps muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophy" title=" hypertrophy"> hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20resonance%20imaging" title=" magnetic resonance imaging"> magnetic resonance imaging</a> </p> <a href="https://publications.waset.org/abstracts/186367/magnetic-resonance-imaging-for-assessment-of-the-quadriceps-tendon-cross-sectional-area-as-an-adjunctive-diagnostic-parameter-in-patients-with-patellofemoral-pain-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186367.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">51</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">55</span> Infectivity of Glossina pallidipes Salivary Gland Hypertrophy Virus (GpSGHV) to Various Tsetse Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guler%20D.%20Uzel">Guler D.

The virus infection is mainly asymptomatic but, in some species under certain conditions, the infection can produce salivary gland hypertrophy (SGH) symptoms. In the laboratory colonized tsetse, flies with SGH have reduced fertility, which negatively affects colony performance. Therefore, a high prevalence of SGH in insect mass rearing represents a major challenge for tsetse control using the sterile insect technique. The main objective of this study is to analyze the impact of Glossina pallidipes SGHV infection in various tsetse species on mortality and productivity and its impact on the symbiotic bacteria. Hypertropied salivary glands (SG) were collected from G. pallidipes into phosphate buffered saline (PBS) to prepare suspension; 2 µl aliquots were injected into adults of several tsetse species (G. pallidipes (Gp), G. p. gambiensis (Gpg), G. brevipalpis (Gb), G. morsitans morsitans (Gmm), G. morsitans centralis (Gmc) and G. fuscipes (Gf)) and the change in virus and symbiont titers were analyzed using qPCR. The development of SGH in the F1 was detected by dissection 10 days after emergence and virus infection was confirmed by PCR. The impact of virus infection on fly mortality and productivity was recorded. 2 µl aliquots were also injected into 3rd instar larvae of the different species and the adult SGs assayed by PCR for virus. Virus positive SGs from each species were homogenized in PBS and pooled within species for injection into larvae of the same species. Flies injected with PBS were used as control. Injecting teneral flies with SGHV caused increasing virus titer over time in all species but no SGH was detected. Dissection of the F1 also showed no development of SGH except in Gp (the homologous host). Injection of SGHV did not have any impact on the prevalence of the tsetse symbionts, but an increase in Sodalis titer was observed correlated with fly age regardless of virus infection. The virus infection had a negative impact on productivity and mortality. SGHV injection into larvae of the different species produced SGHV infected glands in the adults determined by PCR with a rate of 60%, 27%, 16%, 7% and 7% for Gp, Gf, Gpg, Gmm and Gmc, respectively. Virus positive SGs observed in the heterologous species were smaller than SGH found in Gp. No virus positive SG was detected by PCR in Gb and no SGH was observed in any adults except in Gp. Injecting virus suspension from the virus positive SGs into conspecific larvae did not produce any adults with infected SGs (except in Gp). SGHV can infect all tested tsetse species. Although the virus can infect and increase in titer in other tsetse species and affect fly mortality and productivity, no vertical virus transmission was observed in other tsetse species with might indicate a transmission barrier in these species, and virus collected from flies injected as larvae was not infective by injection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA%20viruses" title="DNA viruses">DNA viruses</a>, <a href="https://publications.waset.org/abstracts/search?q=glossina" title=" glossina"> glossina</a>, <a href="https://publications.waset.org/abstracts/search?q=hytrosaviridae" title=" hytrosaviridae"> hytrosaviridae</a>, <a href="https://publications.waset.org/abstracts/search?q=symbiotic%20bacteria" title=" symbiotic bacteria"> symbiotic bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=tsetse" title=" tsetse"> tsetse</a> </p> <a href="https://publications.waset.org/abstracts/55189/infectivity-of-glossina-pallidipes-salivary-gland-hypertrophy-virus-gpsghv-to-various-tsetse-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55189.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">216</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">54</span> The Effect of Different Strength Training Methods on Muscle Strength, Body Composition and Factors Affecting Endurance Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaher%20A.%20I.%20Shalfawi">Shaher A.

Fourteen physical education students accepted to participate in this study. The participants were then randomly divided into three groups, traditional training group (TTG), cluster training group (CTG) and control group (CG). TTG consisted of 4 participants aged ( ± SD) (22.3 ± 1.5 years), body mass (79.2 ± 15.4 kg) and height (178.3 ± 11.9 cm). CTG consisted of 5 participants aged (22.2 ± 3.5 years), body mass (81.0 ± 24.0 kg) and height (180.2 ± 12.3 cm). CG consisted of 5 participants aged (22 ± 2.8 years), body mass (77 ± 19 kg) and height (174 ± 6.7 cm). The participants underwent a hypertrophy strength training program twice a week consisting of 4 sets of 10 reps at 70% of one-repetition maximum (1RM), using barbell squat and barbell bench press for 8 weeks. The CTG performed 2 x 5 reps using 10 s recovery in between repetitions and 50 s recovery between sets, while TTG performed 4 sets of 10 reps with 90 s recovery in between sets. Pre- and post-tests were administrated to assess body composition (weight, muscle mass, and fat mass), 1RM (bench press and barbell squat) and a laboratory endurance test (Bruce Protocol). Instruments used to collect the data were Tanita BC-601 scale (Tanita, Illinois, USA), Woodway treadmill (Woodway, Wisconsin, USA) and Vyntus CPX breath-to-breath system (Jaeger, Hoechberg, Germany). Analysis was conducted at all measured variables including time to peak VO2, peak VO2, heart rate (HR) at peak VO2, respiratory exchange ratio (RER) at peak VO2, and number of breaths per minute. The results indicate an increase in 1RM performance after 8 weeks of training. The change in 1RM squat was for the TTG = 30 ± 3.8 kg, CTG = 28.6 ± 8.3 kg and CG = 10.3 ± 13.8 kg. Similarly, the change in 1RM bench press was for the TTG = 9.8 ± 2.8 kg, CTG = 7.4 ± 3.4 kg and CG = 4.4 ± 3.4 kg. The within-group analysis from the oxygen consumption measured during the incremental exercise indicated that the TTG had only a statistical significant increase in their RER from 1.16 ± 0.04 to 1.23 ± 0.05 (P < 0.05). The CTG had a statistical significant improvement in their HR at peak VO2 from 186 ± 24 to 191 ± 12 Beats Per Minute (P < 0.05) and their RER at peak VO2 from 1.11 ± 0.06 to 1.18 ±0.05 (P < 0.05). Finally, the CG had only a statistical significant increase in their RER at peak VO2 from 1.11 ± 0.07 to 1.21 ± 0.05 (P < 0.05). The between-group analysis showed no statistical differences between all groups in all the measured variables from the oxygen consumption test during the incremental exercise including changes in muscle mass, fat mass, and weight (kg). The results indicate a similar effect of hypertrophy strength training irrespective of the methods of the training used on untrained subjects. Because there were no notable changes in body-composition measures, the results suggest that the improvements in performance observed in all groups is most probably due to neuro-muscular adaptation to training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypertrophy%20strength%20training" title="hypertrophy strength training">hypertrophy strength training</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster%20set" title=" cluster set"> cluster set</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruce%20protocol" title=" Bruce protocol"> Bruce protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20VO2" title=" peak VO2"> peak VO2</a> </p> <a href="https://publications.waset.org/abstracts/90681/the-effect-of-different-strength-training-methods-on-muscle-strength-body-composition-and-factors-affecting-endurance-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90681.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">250</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">53</span> Effect of Cardio-Specific Overexpression of MUL1, a Mitochondrial Protein on Myocardial Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ximena%20Calle">Ximena Calle</a>, <a href="https://publications.waset.org/abstracts/search?q=Plinio%20Cantero-L%C3%B3pez"> Plinio Cantero-López</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Mu%C3%B1oz-C%C3%B3rdova"> Felipe Muñoz-Córdova</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayarling-Francisca%20Troncoso"> Mayarling-Francisca Troncoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20Lavandero"> Sergio Lavandero</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Parra"> Valentina Parra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> MUL1, a mitochondrial E3 ubiquitin ligase anchored to the outer mitochondrial membrane, is highly expressed in the heart. MUL1 is involved in multiple biological pathways associated with mitochondrial dynamics. Increased MUL1 affects the balance between fission and fusion, affecting mitochondrial function, which plays a crucial role in myocardial function. Therefore, it is interesting to evaluate the effect of cardiac-specific overexpression of MUL1 on myocardial function. Aim: To determine heart functionality in a mouse model with cardio-specific overexpression MUL1 protein. Methods and Results: Male C57BL/Tg transgenic mice with cardiomyocyte-specific overexpression of MUL1 (n=10) and control (n=4) were evaluated at 12, 27, and 35 weeks of age. Glucose tolerance curve determination was performed after a 6-hours fast to assess metabolic capacity, treadmill test, and systolic, and diastolic pressure was evaluated by the mouse tail-cuff blood pressure system equipment. The result showed no glucose tolerance curve, and the treadmill test demonstrated no significant changes between groups. However, substantial changes in diastolic function were observed by ultrasound and determination of cardiac hypertrophy proteins by western blot. Conclusions: Cardio-specific overexpression of MUL1 in mice without any treatment affects diastolic cardiac function, thus showing the important role contributed by MUL1 in the heart. Future research should evaluate the effect of cardiomyocyte-specific overexpression of MUL1 in pathological conditions such as a high-fat diet is one of the main risk factors for cardiovascular disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diastolic%20dysfunction" title="diastolic dysfunction">diastolic dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophy%20cardiac" title=" hypertrophy cardiac"> hypertrophy cardiac</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20E3%20ubiquitin%20ligase%201" title=" mitochondrial E3 ubiquitin ligase 1"> mitochondrial E3 ubiquitin ligase 1</a>, <a href="https://publications.waset.org/abstracts/search?q=MUL1" title=" MUL1"> MUL1</a> </p> <a href="https://publications.waset.org/abstracts/156095/effect-of-cardio-specific-overexpression-of-mul1-a-mitochondrial-protein-on-myocardial-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156095.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">73</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">52</span> Development of 90y-Chitosan Complex for Radiosynovectomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Mirzaei">A.

However, its effects on muscular dystrophy remain unknown. This work was undertaken to evaluate the effects of Sulforaphane on Duchenne muscular dystrophy (DMD). Methods: 4-week-old mdx mice were treated with SFN by gavage (2 mg/kg body weight per day) for 8 weeks. Blood was collected from eye socket every week, and tibial anterior, extensor digitorum longus, gastrocnemius, soleus, triceps brachii muscles and heart samples were collected after 8-week gavage. Force measurements and mice exercise capacity assays were detected. GSH/GSSG ratio, TBARS, CK and LDH levels were analyzed by spectrophotometric methods. H&E staining was used to analyze histological and morphometric of skeletal muscles of mdx mice, and Evas blue dye staining was made to detect sarcolemmal integrity of mdx mice. Further, the role of Sulforaphane on Nrf2/ARE signaling pathway was analyzed by ELISA, western blot and qRT-PCR. Results: Our results demonstrated that SFN treatment increased the expression and activity of muscle phase II enzymes NQO1 and HO-1 with Nrf2 dependent manner. SFN significantly increased skeletal muscle mass, muscle force (~30%), running distance (~20%) and GSH/GSSG ratio (~3.2 folds) of mdx mice, and decreased the activities of plasma creatine phosphokinase (CK) (~45%) and lactate dehydrogenase (LDH) (~40%), gastrocnemius hypertrophy (~25%), myocardial hypertrophy (~20%) and MDA levels (~60%). Further, SFN treatment also reduced the central nucleation (~40%), fiber size variability, inflammation and improved the sarcolemmal integrity of mdx mice. Conclusions: Collectively, these results show that SFN can improve muscle function, pathology and protect dystrophic muscle from oxidative damage in mdx mice through Nrf2 signaling pathway, which indicate Nrf2 may have clinical implications for the treatment of patients with muscular dystrophy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sulforaphane" title="sulforaphane">sulforaphane</a>, <a href="https://publications.waset.org/abstracts/search?q=duchenne%20muscular%20dystrophy" title=" duchenne muscular dystrophy"> duchenne muscular dystrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=Nrf2" title=" Nrf2"> Nrf2</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/19659/sulforaphane-alleviates-muscular-dystrophy-in-mdx-mice-by-activation-of-nrf2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19659.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">323</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">50</span> Dialysis Rehabilitation and Muscle Hypertrophy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Itsuo%20Yokoyama">Itsuo Yokoyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Rika%20Kikuti"> Rika Kikuti</a>, <a href="https://publications.waset.org/abstracts/search?q=Naoko%20Watabe"> Naoko Watabe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: It has been known that chronic kidney disease (CKD) patients can benefit from physical exercise during dialysis therapy improving aerobic capacity, muscle function, cardiovascular function, and overall health-related quality of life. This study aimed to evaluate the effectiveness of dialysis rehabilitation. Materials and Methods: A total of 55 patients underwent two-hour resistance exercise training during each hemodialysis session for three consecutive months. Various routine clinical data were collected, including the calculation of the planar dimension of the muscle area in both upper legs at the level of the ischial bone. This area calculation was possible in 26 patients who had yearly plain abdominal computed tomography (CT) scans. DICOM files from the CT scans were used with 3D Slicer software for area calculation. An age and sex-matched group of 26 patients without dialysis rehabilitation also had yearly CT scans during the study period for comparison. Clinical data were compared between the two groups: Group A (rehabilitation) and Group B (non-rehabilitation). Results: There were no differences in basic laboratory data between the two groups. The average muscle area before and after rehabilitation in Group A was 212 cm² and 216 cm², respectively. In Group B, the average areas were 230.0 cm² and 225.8 cm². While there was no significant difference in absolute values, the average percentage increase in muscle area was +1.2% (ranging from -7.6% to 6.54%) for Group A and -2.0% (ranging from -12.1% to 4.9%) for Group B, which was statistically significant. In Group A, 9 of 26 were diabetic (DM), and 13 of 26 in Group B were non-DM. The increase in muscle area for DM patients was 4.9% compared to -0.7% for non-DM patients, which was significantly different. There were no significant differences between the two groups in terms of nutritional assessment, Kt/V, or incidence of clinical complications such as cardiovascular events. Considerations: Dialysis rehabilitation has been reported to prevent muscle atrophy by increasing muscle fibers and capillaries. This study demonstrated that muscle volume increased after dialysis exercise, as evidenced by the increased muscle area in the thighs. Notably, diabetic patients seemed to benefit more from dialysis exercise than non-diabetics. Although this study is preliminary due to its relatively small sample size, it suggests that intradialytic physical training may improve insulin utilization in muscle fiber cells, particularly in type II diabetic patients where insulin receptor function and signaling are altered. Further studies are needed to investigate the detailed mechanisms underlying the muscle hypertrophic effects of dialysis exercise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dialysis" title="dialysis">dialysis</a>, <a href="https://publications.waset.org/abstracts/search?q=excercise" title=" excercise"> excercise</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle" title=" muscle"> muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertrophy" title=" hypertrophy"> hypertrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin" title=" insulin"> insulin</a> </p> <a href="https://publications.waset.org/abstracts/191261/dialysis-rehabilitation-and-muscle-hypertrophy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191261.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">19</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">49</span> Polymer Nanocarrier for Rheumatoid Arthritis Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vijayakameswara%20Rao%20Neralla">Vijayakameswara Rao Neralla</a>, <a href="https://publications.waset.org/abstracts/search?q=Jueun%20Jeon"> Jueun Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Hyung%20Park"> Jae Hyung Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To develop a potential nanocarrier for diagnosis and treatment of rheumatoid arthritis (RA), we prepared a hyaluronic acid (HA)-5β-cholanic acid (CA) conjugate with an acid-labile ketal linker. This conjugate could self-assemble in aqueous conditions to produce pH-responsive HA-CA nanoparticles as potential carriers of the anti-inflammatory drug methotrexate (MTX). MTX was rapidly released from nanoparticles under inflamed synovial tissue in RA. In vitro cytotoxicity data showed that pH-responsive HA-CA nanoparticles were non-toxic to RAW 264.7 cells. In vivo biodistribution results confirmed that, after their systemic administration, pH-responsive HA-CA nanoparticles selectively accumulated in the inflamed joints of collagen-induced arthritis mice. These results indicate that pH-responsive HA-CA nanoparticles represent a promising candidate as a drug carrier for RA therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rheumatoid%20arthritis" title="rheumatoid arthritis">rheumatoid arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=hyaluronic%20acid" title=" hyaluronic acid"> hyaluronic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocarrier" title=" nanocarrier"> nanocarrier</a>, <a href="https://publications.waset.org/abstracts/search?q=self-assembly" title=" self-assembly"> self-assembly</a>, <a href="https://publications.waset.org/abstracts/search?q=MTX" title=" MTX"> MTX</a> </p> <a href="https://publications.waset.org/abstracts/72528/polymer-nanocarrier-for-rheumatoid-arthritis-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72528.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">289</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">48</span> Determination of the Informativeness of Instrumental Research Methods in Assessing Risk Factors for the Development of Renal Dysfunction in Elderly Patients with Chronic Ischemic Heart Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aksana%20N.%20Popel">Aksana N.

Chronic kidney disease (CKD) is associated with inflammation, endothelial dysfunction, and increased activity of the sympathoadrenal system. This circumstance increases the risk of cardiovascular diseases and the progression of kidney pathology. The above determines the need to identify cardiorenal changes at early stages to reduce the risks of cardiovascular complications and the progression of CKD. Objective: To identify risk factors (RF) for the development of CKD in elderly patients with chronic ischemic heart disease (CIHD). Methods: The study included 64 patients (40 women and 24 men) with a mean age of 74.4±4.5 years with coronary heart disease, without a history of structural kidney pathology and CKD. All patients underwent transthoracic echocardiography (TTE) and kidney ultrasound (KU) using GE Vivid 9 equipment (GE HealthCare, USA), and cardiac computed tomography (CCT) using Siemens Somatom Force equipment (Siemens Healthineers AG, Germany) in 3 months and in 1 year. Data obtained were analyzed using multiple regression analysis and nonparametric Mann-Whitney test. Statistical analysis was performed using the STATISTICA 12.0 program (StatSoft Inc.). Results: Initially, CKD was not diagnosed in all patients. In 3 months, CKD was diagnosed: stage C1 had 11 people (18%), stage C2 had 4 people (6%), stage C3A had 11 people (18%), stage C3B had 2 people (3%). After 1 year, CKD was diagnosed: stage C1 had 22 people (35%), stage C2 had 5 people (8%), stage C3A had 17 people (27%), stage C3B had 10 people (15%). In 3 months, statistically significant (p<0.05) risk factors were: 1) according to TTE: mitral peak E-wave velocity (U=678, p=0.039), mitral E-velocity DT (U=514, p=0.0168), mitral peak A-wave velocity (U=682, p=0.013). In 1 year, statistically significant (p<0.05) risk factors were: according to TTE: left ventricular (LV) end-systolic volume in B-mode (U=134, p=0.006), LV end-diastolic volume in B-mode (U=177, p=0.04), LV ejection fraction in B-mode (U=135, p=0.006), left atrial volume (U=178, p=0.021), LV hypertrophy (U=294, p=0.04), mitral valve (MV) fibrosis (U=328, p=0.01); according CCT: epicardial fat thickness (EFT) on the right ventricle (U=8, p=0.015); according to KU: interlobar renal artery resistance index (RI) (U=224, p=0.02), segmental renal artery RI (U=409, p=0.016). Conclusions: Both TTE and KU are very informative methods to determine the additional risk factors of CKD development and progression. The most informative risk factors were LV global systolic and diastolic functions, LV and LA volumes. LV hypertrophy, MV fibrosis, interlobar renal artery and segmental renal artery RIs, EFT. <p class="card-text"><strong>Keywords:</strong> <a
