A Strontium‐Based Polyphenol Nanozyme Reverses Cisplatin‐Related Acute Kidney Injury Through Near‐Infrared‐Enhanced PI3K/AKT Pathway Inhibition and Macrophage M2 Directional Polarization

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Cisplatin‐related acute kidney injury (CP‐AKI) is a serious complication of cisplatin (CP) treated patients with cancer with high morbidity and mortality rates. It is directly related to the abnormal accumulation of CP in renal tubular epithelial cells, causing metabolic toxicity, DNA damage, and oxidative stress.

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

气体绝缘开关柜漏气问题的分析及处理

open access: yesGaoya dianqi, 2010
气体绝缘开关柜漏气问题是影响开关设备安全可靠运行的关键问题。笔者以AEⅡ-40.5型气体绝缘开关柜为例,针对气室接地穿墙绝缘子出现漏气的问题,通过对接地穿墙绝缘子各相关环节和要素的逐一分析判断的方法,最终判定:设备在抽气和充气过程中,由于气室的弹性变形所产生的对接地穿墙绝缘子的非正常作用力,是导致接地穿墙绝缘子损伤而漏气的真正原因。并采取了改变接地穿墙绝缘子的刚性连接为软连接的措施,从根本上消除了气室变形对接地穿墙绝缘子的影响,彻底解决了由于接地穿墙绝缘子损伤而产生漏气的问题 ...

Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...
