1生物结皮光合作用对光温水的响应及其对结皮空间分布格局的解译——以黄土丘陵区为例显示文摘生物结皮是具有生命活性的地表覆被物,在黄土丘陵半干旱区广泛发育。迄今有关该区不同类型生物结皮的光合、呼吸作用潜力及其影响因素还不清楚。通过野外调查采样,利用室内半开放光合测定系统,测定了黄土丘陵区典型的藻类(3年生)、藓类(土生扭口藓)生物结皮(13年生)光合及呼吸作用过程对水分、温度及光照等环境因子的响应,在此基础上,解释了不同类型生物结皮空间分布格局的内在原因。结果表明:(1)在适合的光温水条件下,生物结皮的光合及呼吸作用强度取决于生物组成,研究区藓结皮的光合及呼吸作用速率显著高于藻结皮;(2)水分是生物结皮光合、呼吸作用的关键影响因子,只有当水分含量达到一定水平,才有光合及呼吸的可能。黄土丘陵区藓类及藻类生物结皮光合作用最适水分条件分别为80%-100%和40%-80%田间持水量。(3)藓类及藻类生物结皮光合作用光补偿点PAR均低于10μmol.m-2.s-1,光饱和点PAR分别为1000和800μmol.m-2.s-1,研究中2类生物结皮均未出现光抑制现象。(4)温度显著影响生物结皮的光合及呼吸作用,研究区藓类及藻类生物结皮的最适光合温度分别为20-25℃和25-30℃。(5)生物结皮光合作用对含水量及温度的响应可以解释结皮的空间分布特征。藻类植物光合作用的最适含水量较低而最适温度较高,因此在失水较快的阳坡及开阔地面上依然可以大面积发育;而藓类植物光合作用对水分条件要求较高,因此在水分条件较好的阴坡、低洼地才易演替至藓结皮阶段。赵允格 许明祥 Jayne Belnap 2010生态学报2010,30,17:35

3响应面试验优化链霉菌Z331-A的发酵条件显示文摘链霉菌Z331-A是一株活性很好的生防菌,为提高链霉菌Z331-A发酵液的抑菌效果,对其发酵条件进行优化。该研究在单因子试验基础上,利用Plackett-Burman设计筛选出影响菌株Z331-A发酵的3个关键因子为发酵时间、接种量、摇瓶转速;然后通过响应面试验确定最佳发酵条件。结果表明,链霉菌Z331-A最佳发酵条件为发酵时间7.2d,接种量5.7%,摇瓶转速210r/min。在此最佳发酵条件下,抑菌圈直径可达24.30 mm,比未优化前(19.20mm)提高了26.56%。表明响应面法优化的链霉菌Z331-A发酵工艺效果良好。范丽霞 胡晓苹 刘文波 RAJAOFERA Mamy Jayne Nelly 唐中发 缪卫国 2018中国酿造2018,37,4:7

9从关联的角度理解数学课堂上学生的思维活动——一堂美国数学课堂教学分析显示文摘对同一数学问题,学生会产生不同甚至相互矛盾但却都合理的解释,并由此产生不同的解题方法、不同的答案;学生不同的观点隐含着不同的思维方式;学生思维的动态变化挑战了传统意义上的线性教案在数学课堂教学的合理性.在数学教学中,我们应认识到:学生的思维方式是丰富多彩的;学生的思维是相互关联、动态变化的,老师必须给予学生充分的自主性;不能用孤立、片面的观点分析学生的解题思路,而应该在各种解题思路的联系中加以分析.Thomas E.Ricks 吕联芳 Jayne M.Fleener 2008数学教育学报2008,17,6:3
10Brief electrical nerve stimulation enhances intrinsic repair capacity of the focally demyelinated central nervous system显示文摘Our lab has shown that brief electrical nerve stimulation(ES)has a dramatic impact on remyelination of lysophosphatidyl choline(LPC)-induced focally demyelinated rat peripheral nerves,while also inducing an axon-protective phenotype and shifting macrophages from a predominantly pro-inflammatory toward a pro-repair phenotype.Whether this same potential exists in the central nervous system is not known.Thus,for proof of principle studies,the peripheral nerve demyelination and ES model was adapted to the central nervous system,whereby a unilateral focal LPC-induced demyelination of the dorsal column at the lumbar enlargement where the sciatic nerve afferents enter was created,so that subsequent ipsilateral sciatic nerve ES results in increased neural activity in the demyelinated axons.Data reveal a robust focal demyelination at 7 days post-LPC injection.Delivery of 1-hour ES at 7 days post-LPC polarizes macrophages/microglia toward a pro-repair phenotype when examined at 14 days post-LPC;results in smaller LPC-associated regions of inflammation compared to non-stimulated controls;results in significantly more cells of the oligodendroglial lineage in the demyelinated region;elevates myelin basic protein levels;and shifts the paranodal protein Caspr along demyelinated axons to a more restricted distribution,consistent with reformation of the paranodes of the nodes of Ranvier.ES also significantly enhanced levels of phosphorylated neurofilaments detected in the zones of demyelination,which has been shown to confer axon protection.Collectively these findings support that strategies that increase neural activity,such as brief electrical stimulation,can be beneficial for promoting intrinsic repair following focal demyelinating insults in demyelinating diseases such as multiple sclerosis.All animal procedures performed were approved by the University of Saskatchewan's Animal Research Ethics Board(protocol#20090087;last approval date:November 5,2020).Lydia Ayanwuyi Nataliya Tokarska Nikki A.McLean Jayne M.Johnston Valerie M.K.Verge 2022Neural Regeneration Research2022,17,5:3

13Prevalence of and risk factors for tuberculosis among healthcare workers in Chinese tuberculosis facilities显示文摘Background:China is one of 22 countries with a high tuberculosis(TB)burden in the world.Healthcare workers(HCWs)have a high risk of contracting Mycobacterium tuberculosis infection due to insufficient infection control practices.We conducted a cross-sectional study to explore the prevalence of TB and its associated risk factors among HCWs in Chinese TB facilities.Methods:Two hundred and forty-one TB facilities employing a total of 9663 HCWs were selected from 12 provinces in China to represent healthcare settings at the provincial,prefectural,and county levels.Structured questionnaires were used to collect information on TB infection control practices and HCWs in those facilities.Data was double entered into EpiData 3.1;TB prevalence and associated risk factors were analyzed using SPSS 21.0 with bivariate and multivariate regression models.Results:The results showed that 71 HCWs had been diagnosed with TB,accounting for a prevalence of 760/100000.The multivariate analysis showed that associated risk factors included belonging to the age group of 51 years and above(aOR:6.17,95%CI:1.35-28.28),being a nurse(aOR=3.09,95%CI:1.15-8.32),implementation of 0-9 items of management measures(aOR=2.57,95%CI:1.37-4.80),and implementation of 0-1 items of ventilation measures(aOR=2.42,95%CI:1.31-4.47).Conclusion:This was the first national large sampling survey on TB prevalence among HCWs in China.It was found that the implementation of TB infection control practices in some facilities was poor.The TB prevalence in HCWs was higher than that in the general population.Therefore,TB infection control practices in Chinese medical facilities should be strengthened.Xiao-Ning Wang Tian-Lun He Meng-Jie Geng Yu-Dan Song Ji-Chun Wang Min Liu Sarah Jayne Hoosdally Ana Luíza Gibertoni Cruz Fei Zhao Yu Pang Yan-Lin Zhao Guang-Xue He 2018Infectious Diseases of Poverty2018,7,1:2
