自从70年代提出生物自由基伤害学说以来，现已被广泛地用于研究需氧生物细胞的毒害机理．细胞自由基产生和清除的平衡遭到破坏时，自由基的增加会导致细胞的伤害．特别是自由基袭击了生物膜系统，使膜的磷脂双分子层中不饱和脂肪酸中的不饱和键发生过氧化而分解，从而造成整体膜的破坏．即所谓的“膜脂过氧化作用”．...

Corner separation at the junction of blade surfaces and end walls remains a significant challenge in compressor cascade performance. This study proposes a passive flow control strategy inspired by the geometric arrangement of biological fish scales to address this issue. A fish scale-like surface st...

In order to understand the mechanism of the detoxication of the fluoride poisoned silkworm by naphthy-lamine compounds such as CRL, the effect of CRL on the activity of the glutathione peroxidase (GSH-Px) in the hemolymph of fluoride poisoned silkworm larvae was studied. For normal fifth instar larv...

ABSTRACT: The Pearl River Mouth Basin (PRMB) is one of the most petroliferous basins on the northern margin of the South China Sea. Knowledge of the thermal history of the PRMB is significant for understanding its tectonic evolution and for unraveling its poorly studied source-rock maturation histor...

ABSTRACT Background Earlier studies have proposed the effect of education level and sedentary behavior (SB) on the incidence of depression in adults. However, the association between the combination of education level and SB and depression in adults has not yet been investigated. Methods This study...

Porcine reproductive and respiratory syndrome virus (PRRSV) actively induces cell apoptosis both in vitro and in vivo, which can contribute critically to viral pathogenesis. Previous studies have shown that the PRRSV nonstructural protein 4 (nsp4) is an important mediator of this process, but the un...

Real-time ash content control in dense medium coal separation is challenged by time lags between detection and density adjustment, along with nonlinear/noisy signals. This study proposes a hybrid model for clean coal ash content in dense medium separation by integrating empirical mode decomposition,...

The glycoprotein 5 (GP5) of porcine reproductive and respiratory syndrome virus (PRRSV) is a multi-functional protein that plays important roles in virus assembly, entry and viral anti-host responses. In the present study, we investigated the cellular binding partners of GP5 by using lentivirus tran...
