Placental insufficiency markers to assess the risk of non‐chromosomal genetic conditions in early‐onset fetal growth restriction

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 492-499, April 2026.
ABSTRACT Objectives To assess the value of placental insufficiency markers for estimating the risk of genetic anomalies in fetuses with isolated early‐onset fetal growth restriction (FGR), defined as an estimated fetal weight ≤ 3rd percentile diagnosed ≤ 28 + 6 weeks' gestation.

Metabolomic Study on the Advanced Pancreatic Cancer Model in Nude Mouse [PDF]

open access: yes, 2016
胰腺癌是一种恶性程度极高的消化道类恶性肿瘤,早期无显著病征,病人在确诊时病情基本已处于中晚期,而研究显示,直径小于2cm和1cm的胰腺癌术后5年生存率分别可达30%-60%和超过75%,远高于中晚期术后5年生存率。 本文为课题“基于核磁共振的代谢组学技术发现胰腺癌的生物标志物及早期诊断应用”的一部分。整个课题目的在于通过系统分析动物和人类胰腺癌中晚期模型代谢通道的异同点,然后通过构建动物早期胰腺癌模型,并结合中晚期动物与人类胰腺癌代谢通路的共同点 ...

Lessons from an eradication under multiple constraints of an island rat population of record density

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

肾透明细胞癌患者术前血浆GAPDH cfNA水平对诊断及预后的价值

open access: yesZhongguo shiyan zhenduanxue, 2021
肾透明细胞癌(ccRCC)是最常见的肾恶性肿瘤[1],但由于缺乏特异性的生物标志物,目前临床上对于ccRCC预后的判断仍然依赖患者或肿瘤的临床和病理特征。寻找一种有效的生物标志物对于ccRCC患者的术后检测以及管理至关重要[2]。循环肿瘤细胞(CTCs)已经被证明在肾细胞癌患者的早期诊断和预后中具有潜在的应用价值[3-4]。

Activatable Ferritin Nanocomplex for Real-Time Monitoring of Caspase-3 Activation during Photodynamic Therapy(PDT) [PDF]

open access: yes, 2016
随着分子影像学的发展,治疗诊断学已成为现在医学研究的热点。目前各种 先进的医学成像技术已被用在医学成像,例如光学成像,磁共振成像(MRI),单 光子发射计算机断层扫描(SPECT),正电子发射断层扫描(PET)和光声成像, 从而促进了分子成像探针和医学成像的发展。分子成像探针结构复杂,能够结合 特定生物标志物并产生成像信号用于疾病的诊断。迄今为止,一些成像探针已应 用到临床,例如18F-FDG,但是探针的低靶向性特点限制了成像探针的应用。因 此 ...

尿液检测技术在膀胱癌无创诊断中的研究进展 [PDF]

open access: yes, 2021
膀胱癌是泌尿系统最常见的肿瘤之一,当前膀胱镜检查加病理活检是确诊和随访观察治疗后肿瘤复发进展的金标准,但该检查技术有创且存在有时因尿道狭窄、肿瘤出血致视野不清、取材不充分而影响判断等缺点。因此开发能媲美于膀胱镜检查的无创诊断方法一直是研究者们关注的热点。本文通过文献检索分析归纳总结近10年关于膀胱癌尿液无创诊断研究现状 ...

中性粒细胞载脂蛋白在感染性疾病应用的临床进展

open access: yesZhongguo shiyan zhenduanxue, 2023
人中性粒细胞载脂蛋白(human neutrophil li- pocalin, HNL)以45 kD二硫键连接的同源二聚体存在,是诊断急性细菌感染性疾病的生物学标志物[1-4]。近年来研究发现HNL在感染性疾病中显著升高,HNL作为新型生物标志物在感染性疾病中研究众多,现就此综述如下。1 中性粒细胞载脂蛋白的生物学特性中性粒细胞载脂蛋白是中性粒细胞二级颗粒的主要成分,由180个氨基酸残基组成的相对质量为45 kD的多肽链,
