The objective of the study was to synthesize tetrazole molecules featuring nitro groups positioned at the para and meta locations. We aimed to assess their effectiveness in inhibiting corrosion of mild steel in a 1 M HCl solution at 298 K. Tetrazoles with 2,5-disubstitution were created using [3 + 2] cycloaddition and N-alkylation techniques, with a particular emphasis on synthesizing molecules that contain nitro groups.

Methods: Rats were divided into four groups (n = 8/group): (1) Control, (2) Chitosan only, (3) TBHQ only, and (4) Chitosan + TBHQ.
Results: TBHQ exposure led to significant cognitive impairments and increased oxidative stress, marked by elevated malondialdehyde (MDA) and decreased superoxide dismutase (SOD) and glutathione (GSH) levels.
Nateglinide belongs to the meglitinide class of insulin secretagogues. It is used as an oral hypoglycemic agent for the treatment of type 2 diabetes mellitus. Nateglinide is an amino acid derivative of D-phenylalanine that binds to the ATP-sensitive potassium channels in pancreatic beta cells and stimulates the secretion of insulin.

Background/purpose: Rural adults and children are at higher risk for overweight and obesity. However, there are relatively few lifestyle modification programs available for these high-risk families, mainly because of the difficulty in reaching them. This mindfulness-based motivational interviewing (MM-based-MI) pilot aimed to improve parents' healthy eating index (HEI), collective family efficacy, family satisfaction, perceived stress, and depressive symptoms as well as parent-child dyads' eating patterns, physical activity (PA), and body mass index (BMI).
