1Single-session minimally invasive management of common bile duct stones显示文摘Up to 18% of patients submitted to cholecystectomy had concomitant common bile duct stones.To avoid serious complications,these stones should be removed.There is no consensus about the ideal management strategy for such patients.Traditionally,open surgery was offered but with the advent of endoscopic retrograde cholangiopancreatography(ERCP) and laparoscopic cholecystectomy(LC) minimally invasive approach had nearly replaced laparotomy because of its well-known advantages.Minimally invasive approach could be done in either twosession(preoperative ERCP followed by LC or LC followed by postoperative ERCP) or single-session(laparoscopic common bile duct exploration or LC with intraoperative ERCP).Most recent studies have found that both options are equivalent regarding safety and efficacy but the singlesession approach is associated with shorter hospital stay,fewer procedures per patient,and less cost.Consequently,single-session option should be offered to patients with cholecysto-choledocholithiaisis provided that local resources and expertise do exist.However,the management strategy should be tailored according to many variables,such as available resources,experience,patient characteristics,clinical presentations,and surgical pathology.Ahmed Abdel Raouf ElGeidie 2014World Journal of Gastroenterology2014,20,41:12

3Molecular mechanisms of the anti-obesity potential effect of Moringa oleifera in the experimental model显示文摘Objective: To elucidate the molecular mechanisms of the potent anti-obesity effect of Moringa oleifera Lam.(M. oleifera) ethanolic extract and to clarify the link between these mechanisms and the associated metabolic and vascular risks in the experimental model of visceral obesity.Methods: M. oleifera ethanolic extract was orally administered at 600 mg/kg body weight in obese female rats daily for 12 weeks. At the end of treatment, body weight was determined, and the atherogenic index, coronary artery index, glucose level, insulin resistance status, liver and kidney functions were assessed. Also, the m RNA of leptin, adiponectin and resistin in visceral adipose tissue was determined by quantitative real time-PCR.Results: The results showed that M. oleifera extract down-regulated m RNA expression of leptin and resistin, while it up-regulated adiponectin gene expression in obese rats relative to untreated obese control counterparts. This amelioration of genes expression was paralleled by a reduction in body weight and improvement of the atherogenic index and coronary artery index, as well as glucose level and insulin resistance value without adverse effects on liver or kidney functions, versus the untreated obese control ones.Conclusions: It is reasonable to assume that the anti-obesity, anti-atherogenic and antidiabetic properties of M. oleifera are mechanistically achieved via working directly on the adipokines of the visceral adipose tissue. Therefore, M. oleifera may be a good therapeutic candidate for the symptoms of metabolic syndrome.Fateheya Mohamed Metwally Hend Mohamed Rashad Hanaa Hamdy Ahmed Asmaa Ahmed Mahmoud Ehab Ragaa Abdol Raouf Aboelfetoh Mohamed Abdalla 2017Asian Pacific Journal of Tropical Biomedicine2017,7,3:2
4Equilibria in Interdependent Natural-gas and Electric Power Markets: an Analytical Approach显示文摘Natural-gas and electric power systems and their corresponding markets have evolved over time independently. However, both systems are increasingly interdependent since combined cycle gas turbines that use natural gas to produce electricity increasingly couple them together. Therefore, suitable analysis techniques are most needed to comprehend the consequences on market outcomes of an increasing level of integration of both systems. There is a vast literature on integrated natural-gas and electric power markets assuming that the two markets are operated centrally by a single operator. This assumption is often untrue in the real world, which necessitates developing models for these interdependent yet independent markets. In this vein, this paper addresses the gap in the literature and provides analytical Nash-Cournot equilibrium models to represent the joint operation of natural-gas and electric power markets with the assumption that the market participants in each market make their own decisions independently seeking the maximum profits, as often is the case in the real world. We develop an analytical equilibrium model and apply the Karush-Kuhn-Tucker (KKT) approach to obtain Nash-Cournot equilibria for the interdependent natural-gas and electric power markets. We use a double-duopoly case to study the interaction of both markets and to derive insightful analytical results. Moreover, we derive closed-form analytical expressions for spot-market equilibria in both natural-gas and electric power markets, which are relevant and of practical significance for decision makers. We complement the double-duopoly study with a detailed sensitivity analysis.Seyedamirabbas Mousavian Beheshteh Raouf Antonio J.Conejo 2021Journal of Modern Power Systems and Clean Energy2021,9,4:2

8基于黄河鲤新品系IGF2b基因SNPs获取体系的建立及在该品系选育中的应用显示文摘为了建立鲤 IGF2b (insulin-like growth factor 2)基因全基因组信息 SNPs (single nucleotide polymorphism)的获取体系,并验证该获取体系在黄河鲤新品系选育中运用的适用性,本研究首先对 10个不同鲤品种的 33个鲤个体重测序数据进行分析,整体上了解 IGF2b 基因的单核苷酸位点及其在基因组上的分布情况。然后在基因组 DNA 水平上分段获取 IGF2b 基因的 SNPs 信息,并以不同的鲤品种验证引物的适用性,最后在黄河鲤新品系中检测其应用。研究结果:获得 8 对聚合酶链式反应(polymerase chain reaction, PCR)引物进行分段克隆的结果,并通过直接测序和限制性片段长度多态性来获取相应的 SNPs。经过直接测序,本文对黄河鲤、建鲤、黄河鲤和建鲤的正反交后代进行 PCR 检测发现条带单一,目地片段正确;结合黄河鲤新品系的体重数据,本文又以 IGF2b3#引物检测到一个与体重明显相关的 SNPs,同时检测到一个与该基因表达量相关的另一个 SNPs。本研究的方法能够在该基因全基因组范围内开展鲤分子育种中 SNPs 的检测,并验证发现黄河鲤新品系 IGF2b3#引物 227 号位点处,出现的突变位点使体重降低,且有一处 SNPs 与其表达量有关。这将为其他物种、其他功能基因的多态性分子标记研究提供思路。谢元澄 李欣原 苏胜彦 梁敬东 徐跑 贺鑫晋 Bouzoualegh Raouf 2019中国水产科学2019,26,4:2
