The activity of cyanide-sensitive, Cu-Zn superoxide dismutase (SOD) was studied in liver sytosols from H-2 congenic strains of mice. Higher SOD activity was found in livers of mice having H-2b/A.BY, B10, and C3H.SW/haplotypes than in those of H-2a, H-2k and H-2d haplotypes. Segregation studies supported these correlations. In H-2 recombinant strains of mice, the genes influencing the liver SOD activity occur, as ascertained by mapping techniques, at or near the H-2d region of the major histocompatibility complex.

This study was designed to evaluate the dose-dependent efficacy of neurotensin receptor-1 (NTSR1) agonist PD149163 in the amelioration of the lipopolysaccharide (LPS)-induced apoptosis in the gastrointestinal tract (GIT) of mice. PD149163 is an analogue of NTS, a GIT tri-decapeptide with anti-inflammatory and anti-oxidative effects. Swiss-albino mice (female/8 weeks/25 ± 2.

Piperine is an amide alkaloid isolated from the black pepper plant. This study examined the pain‑relieving activity of piperine against paclitaxel (PTX)‑induced neuropathy. Male mice were divided into 6 groups: Sham‑operated group (remained intact), PTX group (PTX‑treated mice receiving normal saline), PTX+ piperine 10, 25, and 50 mg/kg groups (PTX‑treated mice receiving piperine) and positive control group (PTX‑treated mice receiving imipramine 10 mg/kg).

Heavy metal pollution, especially arsenic toxicity, significantly impairs plant growth and development. Phenolic acids, known for their antioxidant properties and involvement in stress signaling, are gaining increased attention as plant secondary metabolites with the potential to enhance plant resistance to these stressors. This study aimed to investigate the effects of different concentrations of syringic acid (SA1, 10 μM; SA2, 250 μM; SA3, 500 μM) on growth, photosynthetic parameters, and antioxidant activity in lettuce seedlings subjected to arsenic stress (As, 100 μM).

This study aimed to explore the mechanism by which Zn retards Fe toxicity by analyzing the morphological, photosynthetic, and chloroplast physiological parameters of wheat seedlings treated with either single or combined Zn and Fe. Different behavior of the seedlings was observed under untreated and treated conditions. The most discriminating quantitative traits were associated with leaf area, biomass dry mass and fresh mass, net photosynthetic rate, intercellular CO concentration, stomatal conductance, transpiration rate of seedlings, Hill reaction, Mg-ATPase and Ca-ATPase activities, malondialdehyde and O contents, and glutathione reductase, ascorbate peroxidase, peroxidase, and superoxide dismutase activities and their gene expression in the seedling chloroplast.
