Bioflavonoids (polyhydroxyphenols) are ubiquitous components of plants, fruits and vegetables; these compounds are efficient scavengers of free oxygen radicals and peroxides. The aim of this study was to investigate the antioxidative effects of genistein-8-C-glycoside (G8CG) isolated from the flowers of Lipinus luteus L. G8CG dose-dependently inhibited membrane lipid peroxidation and prevented GSH oxidation in human red blood cells and rat liver homogenates under tert-butylhydroperoxide-induced oxidative stress and single whole-body gamma-irradiation (1 Gy) of rats.

The study aimed to elucidate the underlying pharmacological mechanism of the traditional Chinese medicine Pue in ameliorating myocardial ischemia-reperfusion injury (MIRI), a critical clinical challenge exacerbated by reperfusion therapy. In vivo MIRI and in vitro anoxia/reoxygenation (A/R) models were constructed. The results demonstrated that Pue pretreatment effectively alleviated MIRI, as manifested by diminishing the levels of serum CK-MB and LDH, mitigating the extent of myocardial infarction and enhancing cardiac functionality.

Oxidative stress caused by reactive oxygen species (ROS) and superoxides is linked to various cancer-related biological events. Extracellular superoxide dismutase (SOD3), an antioxidant enzyme that removes superoxides, contributes to redox homeostasis and has the potential to regulate tumorigenesis. Histone deacetylase 6 (HDAC6), a major HDAC isoform responsible for mediating the deacetylation of non-histone protein substrates, also plays a role in cancer progression.

Low molecular weight fucoidan (LMWF) has been proved to be more potent than its prototype, many degradation methods have been used to prepare LMWF. This study is conducted to further explore the biological activities of LMWF prepared by ultrasound based on anticoagulation, antioxidation, and inhibition of urate induced pyroptosis and reabsorption transporters overexpression in human renal tubular epithelial cells. Data revealed that ultrasound successfully degraded fucoidan to be LMWF, the product treated for no more than 2.

Intravascular hemolysis releases hemoglobin (Hb) from red blood cells under specific conditions, yet the effect of hemolysis in aquaculture systems remain poorly understood. In this study, a continuous hemolysis model for grass carp was established by injection of phenylhydrazine (PHZ) to investigate the mechanistic impacts of sustained hemolysis. PHZ-induced hemolysis altered liver color, and subsequent hematoxylin and eosin staining revealed substantial Hb accumulation in the head kidney, accompanied by inflammatory cell infiltration and vacuolization in liver tissue.
