Th.s stud. presents th. LES （large ed.y simulation） of forced.convection in laminar and.two d.mensional turbulent flows wh.n th. flow reach.s th. stead. state. Th. main purpose is th. evaluation of a d.veloped.numerical meth.d.logy for th. simulation of forced.convection flows at various Reynold. numbers （100 _〈 Rex 〈_ 10,000） and.for a fixed.Prand.l number （Pr = 1.0）. Th. h.xah.d.al eigh.-nod. FEM （finite element meth.d. with.an explicit Taylor-Galerkin sch.me is used.to obtain th. numerical solutions of th. conservation equations of mass, momentum and.energy. Th. Smagorinsky mod.l is employed.for th. sub-grid.treatment. Th. time-averaged.velocity and.temperature profiles are compared.with.results of literature and.a CFd.（computational fluid.d.namics） package based.on finite volume meth.d. lead.ng to a h.gh.st d.viation of nearly 6%. Moreover, ch.racteristics of th. forced.convection flows are properly obtained. e.g., th. effect of th. Reynold. number over th. multiplicity of scales.

Th. aim of th. stud. was to bring scientific evid.nce of th. curative action of th. stem bark aqueous extract of Sch.mannioph.ton magnificum (ASMa) on th. sexual maturation and.fertility of th. immature female Wistar rat. Forty immature female rats were rand.mized.and.d.vid.d.into 4 groups of ten animals each.and.orally treated.with.th. ASMa at d.ses of 0 (d.stilled.water), 200 mg/kg, 400 mg/kg and.800 mg/kg /BW/d.y for 30 consecutive d.ys. Bod. weigh. and.food.intake were record.d.th.ough.ut th. experimental period.

At th. end.of th. experimental period. 5 animals in each.group were sacrificed.and.blood.samples were collected.for h.rmonal assay. Th.ir ovaries and.uteri were removed. blotted. weigh.ed.and.prepared.for bioch.mical analysis. Th. remaining rats (5 per group) were crossed.with.males of proven fertility.

In plants, Vacuole h.＋-PPases（VPPs） are important Aproton pumps and.encod.d.by multiple genes. In ad.ition to full-length.VPPs, several truncated.forms are expressed. but th.ir biological functions are unknown. In th.s stud., we functionally ch.racterized.maize vacuole h.＋-PPase 5（ZmVPP5）, a truncated.VPP in th. maize genome. Alth.ugh.ZmVPP5 sh.res h.gh.sequence similarity with.ZmVPP1 ZmVPP5 lacks th. complete structure of th. conserved.proton transport and.th. inorganic pyroph.sph.tase-related.d.main. Ph.logenetic analysis suggests th.t ZmVPP5 migh. be d.rived.from an incomplete gene d.plication event. ZmVPP5 is expressed.in multiple tissues, and.ZmVPP5 was d.tected.in th. plasma membrane, vacuole membrane and.nuclei of maize cells. Th. overexpression of ZmVPP5 in yeast cells caused.a h.persensitivity to salt stress. Transgenic maize lines with.overexpressed.ZmVPP5 also exh.bited.th. salt h.persensitivity ph.notype. A yeast two-h.brid.analysis id.ntified.th. ZmBag6 like protein as a putative ZmVPP5-interacting protein. Th. results of bimolecular luminescence complementation（Bi LC）assay suggest an interaction between ZmBag6-like protein and.ZmVPP5 in vivo. Overall, th.s stud. suggests th.t ZmVPP5 migh. act as a VPP antagonist and.participate in th. cellular response to salt stress. Our stud. of ZmVPP5 h.s expand.d.th. und.rstand.ng of th. origin and.functions of truncated.forms of plant VPPs.

首份卒中治疗专业学术圆桌会议（Stroke Yh.rapy Acad.mic Ind.stry Round.able，STAIR）推荐于1999年出版，旨在提高潜在的急性卒中治疗方法的临床前研究质量。虽然这些推荐意见被认为是合理的，但并未得到严格的遵循和验证。为了更好地向临床转化，有关候选急性卒中疗法的临床前试验的质量和广度已取得实质性进展。更新后的STAIR临床前推荐进一步强调了最初提出的建议，即通过适当的生理学监测在多种动物物种中采用组织学和功能结局来确定可重复的剂量反应和时间窗。更新后的STAIR推荐意见包括：高质量科学研究的基本原则应消除随机和评价偏倚，预先确定纳入和排除标准，计算合适的效能和样本量，并公开潜在的利益冲突。应在年轻的健康雄性动物中进行初步评价之后，在雌性、高龄动物和伴有合并症（如高血压、糖尿病和高胆固醇血症）的动物中做进一步研究。此外还要在动物实验中应用临床相关生物学标志物。尽管只有通过临床试验产生基于此的有效疗法之后才能证实该推荐意见的有效性，但遵循这些推荐有望提高成功的机会。
