The product of the ∧0/b （-B/0） differential production cross-section and the branching fraction of the decay ∧0/b→ j.ψ pK-（-B/0→ j.ψ-K＊（892）0）is measured as a function of the beauty hadron transverse momentum, pT, and rapidity, y. The kinematic region of the measurements is pT〈20 GeV/c and 2.0 〈g〈4.5.The measurements use a data sample corresponding to an integrated luminosity of 3fb-1 collected by the LHCb detector in pp collisions at centre-of-mass energies √s=7 TeV in 2011 and √s=8 TeV in 2012. Based on previous LHCb results of the fragmentation fraction ratio,f∧0/b/fd,the branching fraction of the decay ∧0/b→ j.ψ pK-is measured to be B（∧0/b→ j.ψ pK-）=（3.17±0.04±0.07±0.34＋0.45/-0.28）×10-4,where the first uncertainty is statistical, the second is systematic, the third is due to the uncertainty on the branching fraction of the decay -B/0 →j.ψ-K＊（892）0,and the fourth is due to the knowledge of f∧0/b/fd.The sum of the asymmetries in the production and decay between ∧0/b and ∧0/bis also measured as a function of pT and y.The previously published branching fraction of ∧0/b→ j.ψ pπ-,relative to that of ∧0/b→ j.ψ pK-,is updated. The branching fractions of ∧0/b→p＋c（→ j.ψp）K-are determined.

The skeletal muscle fiber periphery:A nexus of mTOR-related anabolism

引用

运动医学与健康科学(英文) 2023年第1期5卷 10-19页

作者： Cassidy T.Tinline-Goodfellow Matthew j.lees Nathan Hodson Faculty of Kinesiology and physical Education University of TorontoCanada Institute of Sport Manchester Metropolitan UniversityManchesterUnited Kingdom Department of Sport and Exercise Sciences Manchester Metropolitan UniversityManchesterUnited Kingdom

Skeletal muscle anabolism is driven by numerous stimuli such as growth factors,nutrients(i.e.,amino acids,glucose),and mechanical stress.These stimuli are integrated by the mechanistic target of rapamycin(mTOR)complex 1(mTORC1)signal transduction cascade.In recent years,work from our laboratory and elsewhere has sought to unravel the molecular mechanisms underpinning the mTOR-related activation of muscle protein synthesis(MpS),as well as the spatial regulation of these mechanisms within the skeletal muscle cell.These studies have suggested that the skeletal muscle fiber periphery is a region of central importance in anabolism(i.e.,growth/MpS).Indeed,the fiber periphery is replete with the substrates,molecular machinery,and translational apparatus necessary to facilitate MpS.This review provides a summary of the mechanisms underpinning the mTOR-associated activation of MpS from cell,rodent,and human studies.It also presents an overview of the spatial regulation of mTORC1 in response to anabolic stimuli and outlines the factors that distinguish the periphery of the cell as a highly notable region of skeletal muscle for the induction of MpS.Future research should seek to further explore the nutrient-induced activation of mTORC1 at the periphery of skeletal muscle fibers.

Following the unanimous recommendation of the International Commission on Stratigraphy, the Global boundary Stratotype Section and point (GSSp) for the base of the Cenomanian Stage is defined at a level 36 metres below the top of the Marnes Bleues Formation, a level that corresponds to the the first appearance of the planktonic foraminiferan Rotalipora globotruncanoides Sigal, 1948, on the south side of Mont Risou, east of Rosans, Haute-Alpes, France, where it can be placed in the context of a series of secondary marker levels based on nannofossils, planktonic foraminifera, ammonites,and an ornate δ^13C curve.

Levels of Norovirus and <i>E. coli</i>in Untreated, Biologically Treated and UV-Disinfected Sewage Effluent Discharged to a Shellfish Water

j.urnal of Water Resource and protection 2013年第10期5卷 978-982页

The efficacy of an activated sludge (modified Ludzack-Ettinger (MLE)) UV disinfection processes in removing human noroviruses and E. coli from sewage were compared with the prevalence of these microorganisms in a settled storm discharge from the same sewage treatment works. Both discharges impacted a designated oyster production area. The treatment process delivered average NoV and E. coli reductions of 2.9log10 and 5.2log10, respectively. Most E. coli reductions occurred during the UV disinfection process whereas the MLE process was comparatively more important in reducing NoV levels. A positive relationship was found between NoV removal and measured applied UV dose. The average levels of total NoV in the settled storm tank were of the same order of magnitude of those in screened raw influent at the works. These results highlight the importance of measures to reduce the impact of stormwater discharges to minimise the risk of NoV gastroenteritis associated with the consumption of oysters.

目的:探讨是否可用帕金森病修订的诊断、自主神经作用、心血管作用、更快的疾病进展或药物相互作用来解释服用左旋多巴和司来吉林随机试验病人的额外死亡。设计:采用开放、随机试验、双盲对照和对死亡原因重新再分组的方法进行研究,病人来源于1985～1990年间93所医院,统计截止于1993年12月前死亡的病人,分第一组和第二组。组织单位:英国研究对象:624例没有接受过多巴胺制剂治疗的早期帕金森病病人和在试验期间死亡的120例。研究方法:第一组服用左旋多巴和多巴脱羧酶抑制剂;第二组服用左旋多巴和多巴脱羧酶抑制剂并联合应用司来吉林;第三组单独服用溴隐亭。主要数据:第一、二组520例及由第三组随机分到第一、二组的104例病人的死亡原因。根据专家组意见、修订的诊断和疾病残疾程度、自主神经和心血管疾病记录的证据、死前其它临床特征和药物相互作用,分析死于原来第一、二组病例的特殊额外死因。结果:将随访延期到1995年9月底(平均6.8年),当第二组试验停止时,第二组的危险比与第一组相比是1.32(95%可信范围在0.98～1.79之间)。将第三组病例随机分入第二组后,其危险比是1.54(0.83～2.87)。当包括全部病例时,其危险比是1.33(1.02～1.74),调整其它基本因素后其危险比是1.30(0.99～1.72)。其额外死亡似乎在随访至第三或四年时为最高。病因特异性死亡率显示额外死亡仅源于帕金森病(其危险率是2.5(1.3～4.7))。修订的诊断、疾病的残疾记分、自主神经或心血管意外、其它临床特征或药物相互作用等均未发现有明显差异。第二组与第一组相比,发现第二组病人在死亡前多合并有可能的痴呆和摔倒史。结论:这些结果一致地显示服用左旋多巴和司来吉林联合治疗的病人有额外死亡。修订的诊断、自主神经和心血管意外或药物的相互作用都不能解释此所见,但摔倒和可能的痴呆在第二组中更常见。本试验结果不支持对早期诊断的帕金森病人进行联合治疗。在疾病晚期,对伴有体位性低血压、意识模糊或痴呆的病人,可以应用联合治疗。

AIM: To investigate whether accelerated catabolism of ganglioside and decreased ganglioside content contribute to the etiology of pro-inflammatory intestinal disease. METHODS: Intestinal mucosa from terminal ileum or colon was obtained from patients with ulcerative colitis or inflammatory Crohn's disease(n = 11) undergoing bowel resection and compared to control samples of normal intestine from patients with benign colon polyps(n = 6) and colorectal cancer(n = 12) in this observational case-control study. Gangliosides and phospholipids of intestinal mucosa were characterized by class and ceramide or fatty acid composition using liquid chromatography triple-quad mass spectrometry. Content and composition of ganglioside classes GM1, GM3, GD3, GD1 a, GT1 and GT3 were compared among subj.ct groups. Content and composition of phospholipid classes phosphatidylcholine(pC) and phosphatidylethanolamine were compared among subj.ct groups. Unsaturation index of individual ganglioside and phospholipid classes was computed and compared among subj.ct groups. Ganglioside catabolism enzymes beta-hexosaminidase A(HEXA) and sialidase-3(NEU3) were measured in intestinal mucosa using western blot and compared among subj.ct groups. RESULTS: Relative GM3 ganglioside content was 2-fold higher(p patients with inflammatory bowel disease(IBD) compared to control intestine. The quantity of GM3 and ratio of GM3/GD3 was also higher in IBD intestine than control tissue(p p pecies of ganglioside containing three unsaturated bonds were present in control intestine, but were not detected in IBD intestine. The relative content of pC containing more than two unsaturated bonds was 30% lower in IBD intestine than control intestine(p p p pared to normal intestine. Intesti

与危地马拉圣地亚古多火山喷发相关的地震成因很复杂。不同时间尺度的岩石破裂、流体运移、气体膨胀会引发各种地表运动,包括静态和动态的变形及气压扰动等。详细分析如此复杂的事件可通过测震及附加的其他手段完成,譬如次声、大地测量和可视化监测等。该火山区2009年1月4日的一次爆炸喷发事件前就监测到明显的排气活动、地面倾斜以及地震次声的谐波颤动。这次爆炸事件引起了地表的穹顶隆起、多种爆发脉冲以及随后火山体倾斜导致的再次平衡。本文采用多种手段监测分析圣地亚古多火山的溢流和爆炸活动这一物理过程,并对发生的复合地震进行解析。
