Linchuang shenzangbing zazhi, 2014 急性肾损伤(acute kidney injury,AKI)是住院患者尤其是危重症患者中的常见病。尽管对其研究和认识已不断深入,但其病死率仍居高不下。影响其预后的一个主要原因是缺乏早期诊断的生物标志物。迄今为止,在一些研究中已先后发现了多种具有潜力的AKI生物标志物,并有不少研究结果显示这些生物标志物可能在AKI的早期诊断、病情及疗效监测、预后评估中具有重要意义,有望改善AKI患者预后。

The homogenization of China's city flowers and city trees
People and Nature, Volume 7, Issue 2, Page 530-540, February 2025.Abstract Cultural homogeneity, similar to the loss biodiversity, is a significant global issue that is increasingly gaining attention. City flowers and city trees (CFTs) serve as emblematic cultural symbols of modern cities, often referred to as the ‘green business card’. While many cities have established CFTs in recent decades, there are instances of

Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Trade restrictions are often advocated and implemented as measures to protect wild species threatened by overexploitation. However, in some instances, their efficacy has been questioned, notably by governments in the southern African (SADC) region, which tend to favor a sustainable use approach to wildlife management. We conducted a systematic

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 4, Page 470-479, October 2024.ABSTRACT Objectives Our aim was to examine the prenatal profiles of pregnancies affected by an atypical chromosomal aberration, focusing on pathogenic copy‐number variants (pCNVs). We also wanted to quantify the performance of combined first‐trimester screening (cFTS) and a second‐trimester anomaly scan in detecting these aberrations. Finally, we aimed

液相色谱-质谱联用技术筛查synemin蛋白及其在肾癌诊断中的作用
Zhongguo shiyan zhenduanxue, 2020 目的本研究的目的是利用化学和生物信息学的方法寻找肾癌和癌旁组织的差异蛋白,探讨目标蛋白作为肾癌生物标志物的可能性。方法采用液相色谱-质谱法鉴定肾癌和癌旁组织差异表达的蛋白,借助免疫组织化学的方法观察肾癌和癌旁组织标本中synemin蛋白的表达。结果肾癌与癌旁组织差异表达的蛋白有26个,肾癌组织中过表达18个,低表达8个。synemin蛋白在肾癌组织中的高表达,统计学差异明显 ...
