Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 211-219, August 2026.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

open access: yesConservation 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.

脑钠肽对高龄呼吸困难患者鉴别诊断作用探讨

open access: yesZhongguo shiyan zhenduanxue, 2007
目的评价血浆脑钠肽(BNP)浓度测定在高龄呼吸困难患者中鉴别诊断的作用价值。方法对64例高龄呼吸困难患者根据病史、体征、相关检查确定高龄呼吸困难的主要原因。分为高龄心衰组(33例)和高龄非心源性呼吸困难组(31例),相应设60-79老年(一般老年)对照组。运用快速荧光免疫法测定各组患者血浆BNP浓度。结果高龄心衰组心脏扩大,房颤或房扑发生率及LVEF、BNP值显著高于高龄非心源性呼吸困难组(P0.05)。而高龄非心源性呼吸困难组BNP值显著高于一般老年非心源性呼吸困难组(32例 ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

open access: yesConservation 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.

Risk of minor congenital heart defect in infants conceived via assisted reproductive technology: cohort study from the Copenhagen Baby Heart Study

open access: yesUltrasound 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.
