Zhongguo youzhi, 2023 旨在为山茶油的加工和储藏提供参考，采用Schaal烘箱法对4种工艺山茶油加速氧化，测定山茶油在储藏过程中酸值、过氧化值、p-茴香胺值、脂肪酸、甘油酯以及脂质伴随物的变化情况，并对山茶油质量指标与脂质伴随物进行Pearson相关性分析。结果表明：4种工艺山茶油在储藏过程中的酸值略微升高，上升为初始值的1.09~2.60倍；过氧化值、p-茴香胺值迅速上升，分别上升为初始值的10.31~16.49倍和3.06~4.43倍；α-生育酚含量大幅度下降，损失率为96.19%~100.00%，而角鲨烯 ...

The association between the antioxidant property and ROS system in murine corneal epithelial progenitor cells [PDF]
, 2016 目的：活性氧（ROS）是体内产生的一种高活性分子，低浓度可以调节细胞代谢，基因转录和磷酸酶的活性，高浓度则会导致氧化损伤。目前，有关干细胞自身特性的研究越来越受到学者们的重视，但既往文献中关于干细胞对氧化应激反应以及应激条件下细胞内相关酶活性的变化规律却很少报道。本课题聚焦于，在过氧化氢（H2O2）诱导的氧化应激条件下，活性氧生成关键因子NOX4和抗氧化酶核转录因子NRF2在小鼠角膜上皮祖细胞（TKE2）和成熟的小鼠角膜上皮细胞（MCE）中的不同作用及相关机制。 方法：利用小鼠角膜上皮祖细胞（TKE2 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Aqueous vanadium dioxide (VO2)‐based smart thermal insulation coatings represent a viable strategy to decrease building energy consumption and advance sustainable development goals. However, the inherent instability and limited compatibility with polymer matrices of VO2 hinder its widespread application.

Response mechanism of phytoplankton to reduced seawater acidity/salinity and petroleum hydrocarbon pollution [PDF]
, 2016 浮游植物是海洋主要初级生产者，在海洋生态系统的物质循环和能量流动中起十分重要作用。由于温室效应气体CO2的加剧排放，全球变暖、海冰融化、海平面上升，导致海洋酸度和盐度下降。同时，随着海上石油开发及运输的日益发展，海洋石油泄露事故在全球各地频发，石油烃污染已成为全球主要的海洋污染物之一。 本文针对海水酸度和盐度下降及石油烃污染胁迫下，海洋浮游植物的生理生态响应及其对微量元素生物地球化学循环的影响的科学问题，以浮游植物生物量、抗氧化能力、脂质过氧化、光致产生活性氧等4种指标来探讨浮游植物的生理生态响应 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Toxicity of Cadmium and Its Bioaccumulation in Spotted Babylon,Babylonia areolata: Comparison between Effects of Waterborne and Dietary Exposure [PDF]
, 2013 为比较直接经水体与经营养传递的2种镉(CAdMIuM,Cd)暴露方式对方斑东风螺(bAbylOnIA ArEOlATA)不同组织Cd蓄积和毒性的差异,采用室内模拟法,将螺暴露于含Cd水体(Cd2+:100μg·l-1)或喂食含Cd饵料(牡蛎,34.56μg·g-1以干质量计,先经水体100μg·l-1Cd2+暴露达平衡)30d后再进行15d净化。结果显示,暴露期间,除食物相组螺胃肠道Cd浓度在第10天极显著高于对照组,但随后迅速下降外,其他各组织在2种途径及胃肠道在水相暴露时Cd的浓度均逐渐上升 ...

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 ...
