The effect of pentosan polysulfate on diabetic nephropathy renal tubular epithelial cells injury through regulating p38 MAPK signaling pathway [PDF]
, 2016 目的：观察戊糖多硫酸钠是否通过调控P38MAPK干预糖尿病肾病肾小管上皮细胞的损伤。方法：利用不同浓度（10mmol/L～50mmol/L）葡萄糖刺激肾小管上皮细胞（HK-2）48h，应用CCK-8比色法检测肾小管上皮细胞增殖的改变。利用不同时间段（0h～48h）葡萄糖刺激细胞，用Westernblot法检测P38MAPK蛋白的表达水平。分为正常对照组（control组）、高糖组（HG组，葡萄糖30mmol/L)、戊糖多硫酸钠（PPS）组（PPS200µg/mL)、高糖＋戊糖多硫酸钠组（HG＋

E-选择素基因rs3917422A和rs5355C位点多态性与哈尼族原发性高血压相关性研究
Zhongguo shiyan zhenduanxue, 2009 目的探讨E-选择素基因rs3917422A\C和rs5355C\T位点多态性与哈尼族原发性高血压的关系。方法采用PCR测序技术,对云南哈尼族172例原发性高血压患者和133例正常对照的E-选择素基因rs3917422A\C和rs5355C\T的错义突变进行检测。结果在哈尼族中未发现有rs3917422A多态存在,发现rs5355C基因有多态存在。rs5355C等位基因频率在原发性高血压组中为10.5%,正常对照组中为13.2%,两组之间无显著性差异（P=0.311,P>0.05）。结论哈尼族中E ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.
