水杨酸和高温锻炼与葡萄抗热性及抗氧化的关系

, 2003
对‘京秀’葡萄 (Vitisviniferacv .Jingxiu)高温锻炼和外施水杨酸 (salicylicacid ,SA)都能显著提高其幼苗的抗热性。高温锻炼 1h ,叶片内自由态SA含量急剧升高 ,其后又迅速下降。在抗热性诱导过程中 (高温锻炼 12h或水杨酸喷施后 6h) ,抗氧化酶系统中的过氧化物酶 (POD)、超氧化物歧化酶(SOD)、谷胱甘肽还原酶 (GR)、抗坏血酸过氧化物酶 (APX)的活性都明显升高 ,但过氧化氢酶 (CAT)活性下降 ;高温锻炼或外施SA 1h ,过氧化氢 (H2

血清GFAP、Hcy、Tau联合检测对脑白质病变患者β淀粉样蛋白升高的预测价值

Zhongguo shiyan zhenduanxue
目的评价胶质纤维酸性蛋白(GFAP)、同型半胱氨酸(Hcy)、微管相关蛋白(Tau)联合检测对脑白质病变患者β淀粉样蛋白(Aβ)水平升高的预测价值。方法选取上海市杨浦区控江医院收治的80例脑白质病变患者作为研究对象，依据11C-PIB PET显像结果将患者分为Aβ阳性组及Aβ阴性组，分别测定两组患者血清GFAP、Hcy、Tau水平及Aβ沉积半定量评分，分析GFAP、Hcy及Tau与Aβ沉积半定量评分相关性；多因素Logistic回归分析脑白质病变患者Aβ升高危险因素，受试者工作特征曲线(ROC ...

塔里木河下游胡杨林耗水数值模型/Numerical model of water consumption of Populus euphratica in the lower reaches of Tarim River[J]

, 2014
基于SHAW(Simultaneous Heat and Water)模型,以基本观测要素、植被参数和土壤剖面水热观测数据为模型的输入,对河岸胡杨林的耗水过程、土壤剖面水分变化和能通量进行了较小时间尺度上的模拟研究.结果表明,采用SHAW模型模拟的胡杨耗水量与观测值间存在较大偏差.因此,为了进一步提升水热耦合SHAW模型在干旱区的实用性,引入了地下水位因子GSI (Groundwater-Soil water Interaction),建立了改进的SHAW(GSI-SHAW)模型 ...
