Vacuolar H^＋-translocating pyrophosphatase （V-PPase） is a key enzyme related to plant growth as well as abiotic stress tolerance. In this work, wheat V-PPase genes TaVP1, TaVP2 and TaVP3 were identified. TaVP1 and TaVP2 are more similar to each other than to TaVP3. Their deduced polypeptide sequences preserve the topological structure and essential residues of V-PPases. Phylogenetic studies suggested that monocot plants, at least monocot grasses, have three VP paralogs. TaVP3 transcripts were only detected in developing seeds, and no TaVP2 transcripts were found in germinating seeds. TaVP2 was mainly expressed in shoot tissues and down-regulated in leaves under dehydration. Its expression was up-regulated in roots under high salinity. TaVP1 was relatively more ubiquitously and evenly expressed than TaVP2. Its expression level in roots was highest among the tissues examined, and was inducible by salinity stress. These results indicated that the V-PPase gene paralogs in wheat are differentially regulated spatially and in response to dehydration and salinity stresses.

The authors establish a Cheeger-Müller type theorem for the complex valued analytic torsion introduced by Burghelea and Hailer for fiat vector bundles carrying nondegenerate symmetric bilinear forms. As a consequence, they prove the Burghelea-Haller conjecture in full generality, which gives an analytic interpretation of （the square of） the Turaev torsion.

BACKGROUND Chronic liver disease and cirrhosis is the 12^(th) leading cause of death in the United States. Patients with decompensated-cirrhosis, especially with hepatic encephalopathy/coma(HC), have a higher rate of early readmission and contribute to higher healthcare *** To evaluate the national inpatient trends of discharges, mortalities and financial impacts associated with four common conditions of *** The publicly available Healthcare Cost and Utilization Project National Inpatient Sample database was utilized to examine the temporal trends of total number of discharges, mortalities and inpatient costs related to hospitalization with a primary diagnosis of HC, transjugular intrahepatic portosystemic shunt(TIPS),esophageal varices with bleeding(EV) and spontaneous bacterial peritonitis(SBP) from 2005 to 2014. The ten-year temporal trends were assessed using simple linear regressions and multiple regression analysis. Two-sided P < 0.05 was considered statistically *** From 2005 to 2014, the total number of discharges with cirrhosis-associated complications trended up for HC, SBP and EV(HC by 70% increase, P < 0.0001;SBP by 819% increase, P = 0.0002; EV by 9% increase, P = 0.016), but not for TIPS(P = 0.90). HC related to viral hepatitis showed faster increase by 357%(P <0.0001) in comparison to HC not related to viral hepatitis by 33 %(P = 0.0006).Overall, in-hospital mortality rates for each condition decreased from 2005 to2014(HC by 29% reduction, P = 0.0024; SBP by 26% reduction, P = 0.0038; TIPS by 32% reduction, P = 0.021) except for EV(P = 0.34). After adjustment for inflation, aggregate cost of hospitalization for EV, HC, and SBP significantly increased by 20%, 86%, and 980%, respectively, from 2005 to 2014(all P < 0.02),while TIPS had trend toward decreasing cost by 3%(P = 0.95).CONCLUSION The number of hospitalizations and costs for some of the cirrhosis-associated conditions increased. However, the inpatient mortalit

A.C.拉波-达尼列夫斯基是彼得堡历史学派的理论家和社会学家。从19世纪末起,其史学思想从实证主义逐步过渡到新康德主义批判哲学上来,《历史方法论》的出版标志着他的史学思想演进的完成,最终形成实证主义与新康德主义的创造性综合。拉波-达尼列夫斯基提出历史社会知识理论建构方法并从历史学角度分析社会学。在讨论历史知识理论问题时,他思考一般社会知识认识论问题,进而形成了历史与社会学理论的独特综合,即历史社会知识理论。拉波-达尼列夫斯基认识到该理论的主要任务在于分析知识理论与社会学和历史学的相互关系。在实证主义和新康德主义历史哲学语境下,系统解读他的历史社会知识理论建构,再现他构建人文主义科学体系的愿景,有助于我们了解和研究他的科学遗产。

20世纪前20年,俄国社会矛盾重重,封建统治政权受到了严峻挑战。作为俄国最高行政执行机关的大臣会议,此时的活动对俄国政治、经济和社会生活等方面起着不容忽视的作用。大臣会议主席作为政府首脑,对大臣会议的各项活动发挥着主导作用。从1905年大臣会议体制改革到1917年大臣会议被临时政府取代的近十二年时间里,П.А.斯托雷平成为担任大臣会议主席(1906-1911年)时间最长的政府领导人。主政期间,斯托雷平提出了土地改革、国家行政体制改革等多项改革主张,这些改革对当时的俄国社会产生了深远的影响。斯托雷平和大臣会议的改革内容、改革结果及其影响因素,也一直是学界关注的重点问题。
