Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

Molecular mechanism of the role of ROS signaling pathway in the antioxidant properties of TKE2 cells [PDF]
, 2016 目的:目前ROS在干细胞生物学中的作用还没有得到充分说明和了解。在过氧化氢（H2O2）诱导的氧化应激条件下，我们比较小鼠角膜上皮祖细胞（TKE2）[1]和成熟的小鼠角膜上皮细胞（MCE）的不同反应，重点研究是角膜干细胞的抗氧化细胞特性及相关机制。 方法:以小鼠角膜上皮祖细胞（TKE2）和成熟的小鼠角膜上皮细胞（MCE）为细胞模型，通过CCK8细胞活性实验检测不同浓度H2O2对小鼠角膜上皮的祖细胞（TKE2）和成熟的小鼠角膜上皮细胞（MCE）的影响。利用H2O2处理细胞24小时后 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

A dry eye model of C57BL/6 mouse induced by the topical application of benzalkonium chloride [PDF]
, 2016 目的：探究苯扎氯铵诱导C57BL/6小鼠干眼模型的最佳浓度，与局部应用苯扎氯铵对结膜及颈部淋巴结中炎症因子表达水平的影响。 方法：将60只小鼠分为6组，每组10只小鼠，在小鼠双眼结膜囊内滴入5μl不同浓度的苯扎氯铵（Benzalkoniumchloride，BAC）溶液（浓度分别为0.05%、0.075%、0.10%、0.15%、0.20%、0.25%），每天2次(9am，9pm)，持续7天，诱导小鼠干眼模型，另10只小鼠作为正常对照组，实验过程中，所有小鼠均置于正常环境条件下（即温度23±1 ...

Integrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...

Effects of tributyltin on Glucose Homeostasis in male mice and the recovery feasibility [PDF]
, 2016 三丁基锡(Tributyltin，TBT)是一种有机锡化合物，TBT暴露对糖尿病发生的影响报道很少。本研究以KM小鼠为对象，研究TBT长期暴露导致小鼠糖尿病发生以及停止暴露后患病小鼠的恢复。采用浓度分别为0.5、5和50μg/kg的TBT通过灌胃法对小鼠进行暴露，每3天灌胃1次，暴露持续45天后立刻恢复60天。结果显示： 1.TBT暴露45天后，小鼠体重增加，相对于对照组，50μg/kg组体重增长显著；TBT暴露小鼠的饥饿血糖水平与对照组相比有显著的升高；并出现葡萄糖不耐受。停止TBT暴露恢复60天后 ...

Environmental DNA, Volume 7, Issue 4, July–August 2025.This study evaluates the effectiveness of three environmental DNA sampling approaches–water eDNA, air eDNA, and leech‐derived iDNA–for surveying vertebrate diversity in the Gaoligong Mountains of southwest China. Using five metabarcoding primer sets, we detected 235 vertebrate species.

TetraDENSITY 2.0—A Database of Population Density Estimates in Tetrapods
Global Ecology and Biogeography, Volume 33, Issue 12, December 2024.ABSTRACT Motivation Population density is a fundamental parameter in ecology and conservation, and taxonomic and geographic patterns of population density have been an important focus of macroecological research. However, population density data are time‐consuming and costly to collect, so their availability is limited.

Transgenic overexpression of miR-466a significantly disturbs OREBP/NFAT5 renal expression and induces phenotypes that resemble diabetes insipidus in human [PDF]
, 2012 目的miR-466(a/b/c/e)-5p/3pmiRNAs是两组高度保守的miRNAs，其中-5p组间和-3p组间miRNAs的序列几乎完全一样。生物信息学分析和我们的前期研究显示，miR-466miRNAs可能可以在肾组织中对渗透应激调控转录因子OREBP/NFAT5进行转录后表达调控。我们因此希望研究miR-466a在转基因小鼠中的过表达对小鼠肾组织OREBP/NFAT5的表达和小鼠尿液浓缩机制的影响。 方法通过PCR从小鼠基因组中扩增miR-466a基因序列，将片段插入鸡 ...
