Genetic Confirmations of Dwarf Lemurs Across Madagascar Highlights Complex Biogeographic Patterns 马达加斯加全境鼠狐猴的遗传确认揭示了复杂的生物地理模式

Integrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.
Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

肾细胞癌患者T淋巴细胞亚群动态分析

Zhongguo shiyan zhenduanxue, 2010
目的探讨肾细胞癌患者手术治疗前后外周血T淋巴细胞亚群的变化特征,为了解病情、判断预后提供免疫学依据。方法应用三色荧光素标记CD4、CD8、CD3的单克隆抗体,对外周血淋巴细胞进行标记后,应用流式细胞仪进行检测分析。结果肾细胞癌患者CD3+、CD4+T细胞明显低于正常对照组,CD8+T细胞明显高于正常对照组,CD4/CD8比值倒置;肾细胞癌患者手术后CD3+、CD4+T细胞较术前明显升高,CD4/CD8比值恢复正常。结论肾细胞癌患者T淋巴细胞百分率异常,存在细胞免疫功能紊乱现象;手术后有效去除瘤负荷 ...

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem

Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.
Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

Guard‐cell expression of abscisic acid receptors for engineering water‐use‐efficient plants without trade‐offs in growth

New Phytologist, Volume 248, Issue 2, Page 690-705, October 2025.
Summary Abscisic acid (ABA) induces stomatal closure, reducing transpirational water loss, a critical adaptation for agriculture under drought. However, ABA is often viewed cautiously as stomatal closure limits CO2 uptake for photosynthesis and growth.
