1Diabetes mellitus:An overview on its pharmacological aspects and reported medicinal plants having antidiabetic activity显示文摘Diabetes mellitus is not a single disease but is a group of metabolic disorders affecting a huge numlier of population in the world.It is mainly characterized by chronic hyperglycemia,resulting from defects in insulin secretion or insulin action.It is predicated that the number of diabetes person in the world could reach upto 366 million by the year 2030.Even though the cases of diabetes are increasing day by day,except insulin and oral hypoglycemic drugs no other way of treatment has been successfully developed so far.Thus,the objective of the present review is to provide an insight over the pathophysiological and etiological aspects of diabetes mellitus along with the remedies available for this metabolic disorder.The review also contains brief idea about diabetes mellitus and the experimental screening model with their relevant mechanism and significance mainly used nowadays.Alloxan and streptozotocin are mainly used for evaluating the antidiabetic activity of a particular drug.This review contain list of medicinal plants which have been tested for their antidiabetic activity in the alloxan induced diabetic rat model.From the available data in the literature,it was found that plant having antidiabetic activity is mainly due to the presence of the secondary metabolite.Thus,the information provided in this review will help the researchers for the development of an alternative methods rather than insidin and oral hypoglycemic agents for the treatment of diabetes niellitus,which will minimize the complication associated with the diabetes and related disorder.Patel DK Kumar R Laloo D Hemalatha S 2012Asian Pacific Journal of Tropical Biomedicine2012,2,5:17
2Evaluating the effectiveness of marine actinobacterial extract and its mediated titanium dioxide nanoparticles in the degradation of azo dyes显示文摘Aim of the present study was to synthesize titanium dioxide nanoparticles(TiO2 NPs) from marine actinobacteria and to develop an eco-friendly azo-dye degradation method. A total of five actinobacterial isolates were isolated from Chennai marine sediments, Tamilnadu, India and analyzed for the synthesis of TiO2 NPs using titanium hydroxide. Among these, the isolate PSV 3 showed positive results for the synthesis of TiO2 NPs, which was confirmed by UV analysis. Further characterization of the synthesized TiO2 NPs was done using XRD, AFM and FT-IR analysis. Actinobacterial crude extract and synthesized TiO2 NPs was found efficient in degrading azo dye such as Acid Red 79(AR-79) and Acid Red 80(AR-80). Degradation percentage was found to be 81% for AR-79, 83% for AR-80 using actinobacterial crude extract and 84% for AR-79, 85% for AR-80 using TiO2 NPs. Immobilized actinobacterial cells showed 88% for AR-79 and 81% for AR-80, dye degrading capacity. Degraded components were characterized by FT-IR and GC-MS analysis. The phytotoxicity test with 500 μg/mL of untreated dye showed remarkable phenotypic as well as cellular damage to Tagetes erecta plant. Comparatively no such damage was observed on plants by degraded dye components. In biotoxicity assay, treated dyes showed less toxic effect as compared to the untreated dyes.S Priyaragini S Veena D Swetha L Karthik G Kumar K V Bhaskara Rao 2014Journal of Environmental Sciences2014,26,4:4
3myocardial 以后梗塞巨人让室的 pseudoaneurysm 与严重的心失败介绍显示文摘 Left ventricle(LV) pseudoaneurysm is a late mechanical complication of myocardial infarction.A giant LV pseudoaneurysm is a rare presentation.We report a case of giant LV pseudoaneurysm in a post-MI patient who presented with gross congestive heart failure.The patient had a successful surgical repair of the aneurysm and had a favorable 3-mo outcome.The imaging modality and surgical treatment of the pseudoaneurysm are discussed.Rajesh Vijayvergiya Alok Kumar Sandeep S Rana Harkant Singh Goverdhan D Puri Manphool Singhal 2012World Journal of Cardiology2012,4,11:3
4焊接参数对搅拌摩擦焊接AA2219-T87材料韧性、洋葱圆环的断裂行为的影响(英文)显示文摘与熔焊相比,搅拌摩擦焊可以更好地保持材料的韧性和塑性,提高焊接的抗裂稳定性。本研究旨在提高焊接接头的延性和强度。刀具廓形在保持延性、分析金属流动行为和确定断裂起始点等方面起着重要作用。分析了洋葱圆环不同区域的微观结构,得出了洋葱圆环强度与金属流型的关系。结果表明,洋葱圆环强化了焊缝熔核。肩部和锥形螺纹型线刀具具有优异的力学性能。显微硬度数据表明,断口经过热影响区和热机械影响区等低硬度区。扫描电镜图像显示了细长的晶粒和韧窝,证实了断裂为韧性断裂。Dinesh KUMAR R S MUTHUKUMARAN Vincent XAVIER T VENKATESWARAN D SIVAKUMAR 2019Journal of Central South University2019,26,9:2

6Laparoscopic esophagomyotomy for achalasia in children:Areview显示文摘Esophageal achalasia in children is rare but ultimately requires endoscopic or surgical treatment. Historically, Heller esophagomyotomy has been recommended as the treatment of choice. The refinement of minimally invasive techniques has shifted the trend of treatment toward laparoscopic Heller myotomy(LHM) in adults and children with achalasia. A review of the available literature on LHM performed in patients < 18 years of age was conducted. The pediatric LHM experience is limited to one multiinstitutional and several single-institutional retrospective studies. Available data suggest that LHM is safe and effective. There is a paucity of evidence on the need for and superiority of concurrent antireflux procedures. In addition, a more complete portrayal of complications and long-term(> 5 years) outcomes is needed. Due to the infrequency of achalasia in children, these characteristics are unlikely to be defined without collaboration between multiple pediatric surgery centers. The introduction of peroral endoscopic myotomy and single-incision techniques, continue the trend of innovative approaches that may eventually become the standard of care.T Kumar Pandian Nimesh D Naik Aodhnait S Fahy Arman Arghami David R Farley Michael B Ishitani Christopher R Moir 2016World Journal of Gastrointestinal Endoscopy2016,8,2:2
