共轭亚油酸(Conjugated Linoleic Acid,CLA)具有抗肿瘤、减少脂肪蓄积、调节机体免疫力、抗动脉粥样硬化、调节血糖血压、预防骨质疏松等多种生理活性,已经被广泛应用于医药、食品、保健品、化妆品等领域。由于CLA天然来源较少,以亚油... 详细信息

共轭亚油酸(Conjugated Linoleic Acid,CLA)具有抗肿瘤、减少脂肪蓄积、调节机体免疫力、抗动脉粥样硬化、调节血糖血压、预防骨质疏松等多种生理活性,已经被广泛应用于医药、食品、保健品、化妆品等领域。由于CLA天然来源较少,以亚油酸为底物人工合成制备CLA成为了人们获取CLA的主要途径。本文系统介绍了游离脂肪酸、烷烃酯、甘油酯等不同形式的亚油酸及来源广泛、价格低廉的天然油脂在CLA生产中的运用,并综述了食品发酵中CLA的合成,为优化CLA原料利用、经济高效地获取CLA提供了参考。

为了探究不同水流条件下不同形式的气泡幕对异齿裂腹鱼(Schizothorax oconnori)趋避行为的影响。在黑暗环境下测试了两种流速条件(静水与流水)、三种气量(15、30、45 L/min)及两种摆放角度(与水流方向呈90°和45°)的气泡幕对异齿裂腹鱼的阻拦效果,在静水和流水条件下各设置一组空白对照(气量为0 L/min)。结果显示:(1)在静水条件下,工况2阻拦率最高(50%);在流水条件下,工况7阻拦率最高(50%)。(2)气量15 L/min时,流水及90°摆放阻拦时间显著大于其他工况;30 L/min时,静水及90°摆放阻拦时间远大于其他工况。(3)在静水和流水中,当异齿裂腹鱼尝试次数达到6次左右时对气泡幕表现出适应性,并在48min前通过气泡幕;(4)在流水中各工况下气泡幕的影响距离显著大于静水(P2);气泡幕连续阻拦时间不宜超过48min。实验结果可为实际工程中气泡幕的布置提供参考。

作者：边平达寿张轩李秀央应奇峰陈锦平浙江省人民医院/杭州医学院附属人民医院骨质疏松诊疗中心杭州310024 浙江大学流行病与卫生统计学系杭州310058

目的了解骨转换标志物(bone turnover markers,BTMs)在高龄(≥80岁)男性骨密度(bone mineral density,BMD)变化中的预测价值。方法对737例高龄男性进行连续2次(间隔12个月)血BTMs[包括Ⅰ型胶原羧基端肽(C-telopeptide of type 1 collagen,CTX)β特殊序列、总Ⅰ型胶原氨基端前肽(procollagen1 N-terminal peptide,P1NP)和骨钙素(osteocalcin,OC)]和BMD[包括股骨颈骨密度(femoral neck bone mineral density,FNBMD)、总髋部骨密度(total hip bone mineral density,THBMD)和腰椎1-4骨密度(lumbar bone mineral density,LBMD)]测定,分析12个月前后高龄男性BTMs和BMD的变化趋势及其相关性。结果12个月后,高龄男性血清CTX和LBMD上升,血清OC下降(均P<0.01);基线血清CTX与△FNBMD(r=-0.109,P<0.05)、△THBMD(r=-0.135,P<0.01)呈负相关;△CTX(r=-0.119,P<0.05)和△OC(r=-0.137,P<0.01)与△LBMD呈负相关。结论 BTMs对高龄男性BMD变化有一定的预测价值,其中血清CTX水平越高,其股骨颈和总髋部BMD下降越快,而△CTX、△OC越高,腰椎BMD下降越快。

近来,理论研究预言量子霍尔效应,在外加磁场为0的情况下物质出现的一种全新的量子态可以在HgTe/(Hg,Cd)Te量子阱中实现。我们制造了低密度高迁移率的样品结构,在样品中我们可以通过外加栅极电压调节载流子从n型穿过绝缘区到p型。对于宽度d6.3nm),在绝缘层中也出现接近2e2/h的剩余电导,其中e是电子电荷,h是Planck常数.剩余电导与样品宽度无关,证明这是由边缘态引起的.此外剩余电导可以被微小的外加磁场所破坏.在临界厚度d=6.3nm处发生的量子相变也与磁场诱发的绝缘-金属转变互相独立.这些观察结果为量子自旋霍尔效应提供了实验证据。

大脑的发育、生理功能和病理与神经元和不同类型的神经胶质细胞(如星形胶质细胞、小胶质细胞、少突胶质细胞和少突胶质细胞的前体细胞等)之间的相互作用密切相关。研究脑功能及其功能障碍,除了神经元之外,还需要对不同类型的神经胶质细胞进行研究。近年来,多项技术突破使“神经胶质科学家”能够解决新的具有挑战性的生物学问题。这些技术发展使得以中/高含量工作流研究特定细胞类型的作用成为可能,并在保存完好的环境中对其相互作用进行精细的分析。本综述阐明了几种可能揭示神经胶质细胞在特定脑功能或疾病中作用的尖端实验方法。这些实验方法包括高级细胞培养,诱导多能干细胞(iPSC)衍生的人神经胶质细胞,病毒载体,原位胶质细胞成像,光学遗传学和化学遗传学方法,以及高内涵分子分析。本文还阐述了某些技术的临床转化,通过特定的脑成像方法以监控患者的神经胶质细胞。本文亦讨论了每种技术的优点,缺陷和未来发展,并提供了选定的示例以说明现在如何可以解决特定的“胶质生物学”问题。
