H2O2-initiated free radical oxidation of blood serum lipids was investigated by the chemiluminescence method. The first flash of the chemiluminescence was stimulated by H2O2 decomposition on the reaction, similar to Fenton reaction. The time of the chemiluminescence flash second maximum was correlated with the contents of antioxidants. This dependence had a linear kind and was characterized by the correlation coefficient--0.9898. With increases of concentration of such antioxidant as a hydroquinone, the time of chemiluminescence flash second maximum grew.

Dysregulated tryptophan metabolism contributes to metabolic syndrome in Chinese community-dwelling older adults.

Background: As the prevalence of metabolic syndrome (MetS) rises among older adults, the associated risks of cardiovascular diseases and diabetes significantly increase, and it is closely linked to various metabolic processes in the body. Dysregulation of tryptophan (TRP) metabolism, particularly alterations in the kynurenine (KYN) and serotonin pathways, has been linked to the onset of chronic inflammation, oxidative stress, and insulin resistance, key contributors to the development of MetS. We aim to investigate the relationship between the TRP metabolites and the risk of MetS in older adults.

Background: Intracerebral hemorrhage (ICH) is a common subtype of stroke, characterized by a high mortality rate and a tendency to cause neurological damage. This study aims to investigate the role and mechanisms of lncRNA HCP5 in ICH.
Methods: We simulated ICH in vivo by injecting collagenase into rats and established an in vitro model using hemoglobin-treated BV2 cells.

Herbicide paraquat dichloride, a potent redox agent found its way to natural water bodies and influences their health; however, its impact on the reproductive health of fish is potentially less studied and requires clear investigation. This study was conducted to elucidate its effect on the gonadal health of female fish, Channa punctatus over 60 days. The 96-h LC of test herbicide was calculated as 0.

Nonylphenol (NP) is a ubiquitous environmental endocrine disrupting chemical and oxidative stress inducer in biological systems. Resveratrol (RES) and Naringenin (NG) are phytochemicals possessing antioxidant properties and estrogenic activity. This study was conducted to investigate the toxicity of NP and the mitigating effects of RES and NG on NP toxicity in rats.
