Experimental studies of chronic noise exposure in modern urban life testified about oxidative stress due to the corresponding hormones effects leading to accumulation of reactive oxygen species and endothelial dysfunction. This study aims to evaluate the protective effect of α2-adrenoblockers to modulate oxidative stress and corticosterone levels due to chronic noise exposure. To achieve this, we examined the effects of beditin (2-aminothiozolyl-1,4-benzodioxane) and mesedin (2-(2-methyl-amino-thiozolyl)-1,4-benzodioxane hydrochloride), along with changes in corticosterone, Ca2 + content, and morphological alterations in various tissues under noise-induced stress.

Background: Alcoholic liver disease (ALD) is a significant global health concern, primarily resulting from chronic alcohol consumption, with oxidative stress as a key driver. The ethyl acetate extract of (CGE) exhibits antioxidant and hepatoprotective properties, but its detailed mechanism of action against ALD remains unclear. This study investigates the effects and mechanisms of CGE in alleviating alcohol-induced oxidative stress and liver injury.

Little is known regarding the effects high-intensity training performed in hypoxia on the oxidative stress and antioxidant systems. The aim of this study was to assess the potential effect of 4 weeks of repeated sprint training in hypoxia (RSH) on the redox balance. Forty male well-trained cyclists were matched into two different interventions (RSH, = 20) or in normoxia, RSN, = 20) and tested twice (before (Pre-) and after (Post-) a 4-week of training) for performance (repeated sprint ability (RSA) test), oxidative stress, and antioxidant status.

Methods: Young (3-6 month) C57BL/6 mice were supplemented with MGO (in water) and Gly-Low (in chow). Aortic stiffness was assessed in vivo via pulse wave velocity (PWV) and ex vivo through elastic modulus.

The reproduction of mussels occurs within the water column, and if gametogenesis is successful, gametes are exposed to the surrounding contaminants. Nanoplastics and other emerging contaminants have been gaining vast attention; however, their effects on the reproductive tissues of mussels with sex differentiation are scarce. Here, the effects of polystyrene nanoparticles (50 nm; 10 µg/L), the cytotoxic drug 5-fluorouracil (10 ng/L), and a mixture of the two were evaluated in the gonads of Mytilus galloprovincialis after a 21-day exposure for a multi-biomarker assessment, and after 28 days for the accumulation of nanoplastics.
