高变异Y染色体短串联重复片段检验体系的建立及对北方汉族群体调查

Zhongshan Daxue xuebao. Yixue kexue ban, 2021
目的建立一套五色荧光复合扩增体系，并调查中国北方汉族遗传多态性和父子家系突变情况。方法根据文献筛查出在中国某一群体中突变率为高变异和快速变异的Y-STR基因座，建立一套五色荧光Y-STR复合扩增体系，计算在500个北方汉族无关男性个体中的基因多样性，观察每个样本的Y-STR单倍型，并对中国北方汉族500个父子对进行检测，统计父子间的突变情况。结果成功构建了包含21个Y-STR基因座复合扩增检验体系，在北方汉族群体中基因多态性在0.402 3～0.990 4之间，500个无关个体中未发现有相同的单倍型 ...

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Coalition Breakdown and Subsystem Exit

Policy Studies Journal, EarlyView.
ABSTRACT Why actors choose to work together (or not) to advance policy has been the central area of inquiry within the Advocacy Coalition Framework (ACF). Existing research has mainly emphasized the pathway towards coalition formation and evolution, underscoring the stable patterns of allies and opponents observable in policy processes over a decade or

Synergy Effects of Dual‐Gel‐Assisted Structural Engineering and Bimetallic Doping Regulation Realize Ultrastable High‐Rate Performance of NASICON Cathodes for Sodium‐Ion Batteries

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Na‐superionic‐conductor‐type (NASICON) Na4MnV(PO4)3 (NMVP) is an appealing cathode for sodium‐ion batteries (SIBs), but its application is hindered by Jahn–Teller distortions, sluggish Na+ kinetics and poor conductivity, leading to rapid capacity fade.

Hypertension at 5 months postpartum in women with gestational diabetes

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 202-210, August 2026.
ABSTRACT Objective Gestational diabetes mellitus (GDM) is associated with future maternal cardiovascular disease, independent of the development of Type‐2 diabetes mellitus. As a major cardiovascular risk factor, we examined the incidence and predictors of hypertension at 5 months postpartum in women with previous GDM.

Polyphenol oxidase depletion in Nicotiana benthamiana enhances recombinant protein purification and preserves native protein integrity

New Phytologist, Volume 251, Issue 3, Page 1283-1293, August 2026.
Polyphenol oxidases (PPOs) depletion preserves endogenous proteins at their predicted molecular weights and enhances detectable enzymatic activities. (a) Less RbcL crosslinking in ppo mutant of Nicotiana benthamiana. Leaf extracts were incubated for 1 h, separated on protein gels, stained with Coomassie or analyzed by Western blot with the anti‐RbcL ...
