1. One diamine, putrescine and two polyamines, spermidine and spermine (PAs) of different concentrations, were processed through antioxidant systems in order to study their antioxidant effects. The systems investigated were as follows. 2. "Oxidative stress" was induced in RBCs to investigate filtration parameters, the effect of reduced glutathione (GSH) and the change in lipid peroxidation (LP) superoxide dismutase (SOD) activities. 3. Initiated LP-decreasing characteristics of the substances were studied in pig brain homogenate. 4. The LP-decreasing effect of these PAs were studied in guinea-pig heart tissue homogenate perfused with Tyrode solution, stimulated, and then perfused by the Langendorff method. 5. In all three tests, the antioxidant characteristics of PAs were unambiguously proved.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, extracellular amyloid-β (Aβ) plaque accumulation, and intracellular neurofibrillary tangles. Recent efforts to find effective therapies have increased interest in natural compounds with multifaceted effects on AD pathology. This study explores natural compounds for their potential to mitigate AD pathology using molecular docking, ADME screening, and assays, with ruscogenin─a steroidal sapogenin from emerging as a promising candidate.

() utilizes heme as an iron source from the host during infection. Biliverdin beta and delta (BVIXβ and BVIXδ) are generated by HemO, specific to , while biliverdin alpha is generated from the bacterial BphO system and by mammalian heme oxygenases. Here, we have developed and characterized a quantitative LC-MS/MS assay for the separation of three endogenous isomers, BVIXα, BVIXβ, and BVIXδ.

Preterm births constitute a major public health issue and a chronic, cross-generational condition globally. Psychological and biological factors interact in a way that women from low socio-economic status (SES) are disproportionally affected by preterm delivery and at increased risk for the development of perinatal mental health problems. Low SES constitutes one of the most evident contributors to poor neurodevelopment of preterm infants.

Background: Previous studies have shown that both the composite dietary antioxidant index (CDAI) and sex are strongly associated with a variety of cardiovascular diseases, but sex differences between CDAI and hyperlipidemia are unknown.
Objective: This study utilized data from the National Health and Nutrition Examination Survey (NHANES) to investigate the sex differences between CDAI and hyperlipidemia.
Method: We calculated the CDAI of the six dietary antioxidants using data from NHANES, explored the relationship between CDAI and the prevalence of hyperlipidemia using multivariate logistic regression analysis, and analyzed for potential nonlinear associations using restricted cubic spline.

Background: As an opportunistic bacterial pathogen, Klebsiella pneumoniae (KP) is prone to causing a spectrum of diseases in rabbits when their immune system is compromised, which poses a threat to rabbit breeding industry. Bacillus coagulans (BC), recognized as an effective probiotic, confers a variety of benefits including anti-inflammatory and antioxidant properties.
Aim: The purpose of this study was to investigate whether dietary BC can effectively alleviate hepatic injury caused by KP.
