Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

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.

自发性高血压大鼠TGFβ1/ Smad7通路与心室纤维化的关系
Zhongshan Daxue xuebao. Yixue kexue ban, 2008 [目的]探讨自发性高血压大鼠心室纤维化过程中TGFβ1和其下游分子smad7蛋白的表达规律。[方法]雄性自发性高血压大鼠（SHR）14只随机分为2组，SHR 22周龄组和SHR 14周龄组，另14只WKY大鼠也分为WKY大鼠22周龄组和WKY大鼠14周龄组。在实验动物14周龄和22周龄时，分别测定血压、心室质量指数；以氯胺T法测定心肌羟脯氨酸的含量，免疫组化测定Ⅰ型和Ⅲ型胶原在心肌组织中的表达水平；RT-PCR和Western-blot测定心肌中TGFβ1和其下游分子smad7的表达。[结果 ...

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 1, Page 59-67, July 2026.ABSTRACT Objective Infertility affects up to 20% of couples in high‐income countries, which has led to an increased use of assisted reproductive technology (ART). While previous studies have linked ART to a higher risk of major congenital heart defects (CHD), less is known about the associated risk of minor CHD.
