The question of the function of antioxidants in human health can only be resolved when validated markers of oxidative damage are available. Markers allow determination of the effect of antioxidants on damage to DNA, proteins, and lipids. The final goal is the execution of human intervention studies based on markers that are clearly linked to physiological function. These data will be critical in determining the effectiveness of nutrients in promoting health and wellbeing and reducing disease risk.

The hydration mechanism of 3-methyl-1,2,3-butanetricarboxylic acid (MBTCA), a relevant marker of secondary organic aerosol formation from the atmospheric oxidation of α-pinene, has been investigated using the matrix-isolation infrared spectroscopy technique. The experimental results were supported by theoretical calculations. Monomers of MBTCA and heterocomplexes MBTCA-(HO) were identified.

The human body gets exposed to a variety of toxins intentionally or unintentionally on a regular basis from sources such as air, water, food, and soil. Certain toxins can be synthetic, while some are biological. The toxins affect the various parts of the body by activating numerous pro-inflammatory markers, like oxidative stresses, that tend to disturb the normal function of the organs ultimately.

Purpose: Since extract of the laminated layer (LL) from E. granulosus showed immuno-modulatory effects in vitro and in vivo, we sought to determine its effect on the onset, development, and evolution of experimental auto-immune uveitis (EAU). The latter is a model of some human diseases with ocular inflammation that can cause blindness.

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.

Cancer cells demonstrate remarkable resilience by adapting to oxidative stress and undergoing metabolic reprogramming, making oxidative stress a critical target for cancer therapy. This study explores, for the first time, the redox-dependent anticancer effects of Polydatin (PD), a glucoside derivative of resveratrol, on the human Osteosarcoma (OS) cells SAOS-2 and U2OS. Using cell-based biochemical assays, we found that cytotoxic doses of PD (100-200 µM) promote ROS production, deplete glutathione (GSH), and elevate levels of both total iron and intracellular malondialdehyde (MDA), which are key markers of ferroptosis.
