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.

Journal of Ecology, Volume 114, Issue 8, August 2026.Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

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 ...

Zhongguo youzhi旨在为甘油二酯（DAG）在健康管理和疾病预防中的优化应用提供参考，通过饲喂雄性C57BL/6J系SPF级小鼠高脂高糖饲料建立肥胖小鼠模型，将肥胖模型组小鼠随机分为3组，分别以玉米油、40%DAG玉米油和80%DAG玉米油替代高脂高糖饲料中的猪油，饲喂16周，研究DAG食用油对肥胖小鼠体质量、血脂、肝脏功能的影响。结果表明：不同浓度的DAG食用油均能有效抑制小鼠体质量增加，减少白色脂肪积累，降低血清总胆固醇、甘油三酯及低密度脂蛋白胆固醇水平，同时提升高密度脂蛋白胆固醇水平，减少肝细胞脂肪变性 ...
