D二聚体、FDP、炎性因子联合检测在预测髋关节置换术后LDVT的作用
Zhongguo shiyan zhenduanxue, 2022 目的 探讨D二聚体、FDP、炎性因子联合检测在预测髋关节置换术后LDVT的价值。方法 将内蒙古医科大学附属医院90例股骨颈骨折并接受人工髋关节置换术的患者纳入研究，根据术后7d有无血栓生成血栓组（25例）及无血栓组（65例），并将同期30例健康体检人员设置为健康对照组，比较各组双下肢周径差、外周血D二聚体、FDP、CRP、IL-6、IL-8水平变化，并利用Spearman秩相关分析各指标与大小腿围的相关性。结果 （1）术前三组患者双下肢周径差无统计学差异（P>0.05），术后7d ...

Two decades of changes in the global network of illegal wildlife trade
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Understanding how illegal wildlife trade (IWT) has changed over time is fundamental for biodiversity conservation; however, knowledge of the network remains limited. We used TRAFFIC's IWT dataset, legal trade data from the CITES legal wildlife trade database as a benchmark, and network analysis to identify changes in IWT from 2000 to 2022. The

, 2022 气泡普遍存在于火山熔岩脱气、废水处理和许多其他工业过程中。当气泡相互接触时,不可避免地会发生气泡聚并。Paulsen等人实验研究了外部流体对液滴和气泡聚并的影响,用无量纲数μ/(ργA)~(1/2).给出了外部流体粘度作用的时间。Shaw等人研究了气泡在气-水界面的聚并,描述了水下气泡颈部和表面桥的演化规律。Chen等人通过模拟方法研究了液体粘度、液体密度和表面张力对微泡聚并的影响。气泡聚并的研究大多在毫米量级。由于这一过程发生的时间较短,因此更难在微观尺度上进行捕捉和观察 ...

Integrative Conservation, Volume 5, Issue 1, Page 59-73, March 2026.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Zhongguo shiyan zhenduanxue, 2006 目的探讨下肢骨折病人D二聚体定量检测的临床价值。方法采用增强型乳胶免疫比浊法对109例下肢骨折患者术前、术后第3天及术后第7天进行血浆D二聚体的定量检测,跟踪观察患者病情。结果109例患者有10例并发DVT,并发DVT组术前、术后第3天及术后第7天血浆D二聚体的检测结果有显著性差异（P0.05）。而并发DVT组与未并发DVT组相比较:术前血浆D二聚体的检测结果无显著性差异（P>0.05）;术后第3天血浆D二聚体的检测结果有显著性差异 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...
