Objective: Dietary supplements (DSs) are commonly used supplements among children to support disease treatment, however, overuse and inappropriate prescription of outpatient DS can negatively affect health and treatment costs. This study aimed to evaluate DS use in outpatient treatment in children.

Methods: The present study used a cross-sectional descriptive retrospective method based on data from 188,579 outpatient prescriptions of children for 1 year.

(VA) leaves contain many potential active ingredients and exhibit diverse pharmacological activities. The antihypertensive, anti-inflammatory, and analgesic effects of VA crude and fraction extracts were carried out using Swiss albino mice models. VAE is considered safe to be administered due to LD being greater than 10,000 mg/kg body weight.

The acute and sub-acute toxicity studies were performed in male and female Swiss albino mice as per the guidelines mentioned in OECD. The oral administration of M. tridentata stem extract (MSE) showed no treatment-related mortality and body weight change in mice up to the single dose of 30,000 mg/kg body weight in the acute toxicity study and up to a dose of 30,000 mg/kg/day body weight in the sub-acute toxicity study.

Compounds containing benzimidazole moiety occupy privileged chemical space for discovering new bioactive substances. In continuation of our recent work, 69 benzimidazole derivatives were designed and synthesized with good to excellent yields of 46-99% using efficient synthesis protocol sodium metabisulfite catalyzed condensation of aromatic aldehydes with -phenylenediamines to form 2-arylbenzimidazole derivatives followed by -alkylation by conventional heating or microwave irradiation for diversification. Potent antibacterial compounds against MSSA and MRSA were discovered such as benzimidazole compounds 3k (2-(4-nitrophenyl), -benzyl), 3l (2-(4-chlorophenyl), -(4-chlorobenzyl)), 4c (2-(4-chlorophenyl), 6-methyl, -benzyl), 4g (2-(4-nitrophenyl), 6-methyl, -benzyl), and 4j (2-(4-nitrophenyl), 6-methyl, -(4-chlorobenzyl)) with MIC of 4-16 μg mL.

To overcome the muscle atrophy, such as cachexia and sarcopenia, we tried to find myogenic agents from medicinal plants. From myogenic extract of Coptis japonica, we purified six isoquinoline alkaloids and evaluated their effects on transactivation of myoD and MHC expression in C2C12 cells during differentiation process. Among obtained compounds, magnoflorine most efficiently enhanced the myoblast differentiation by activating the p38 MAP kinase and Akt pathway, and also increased the number of multinucleated and cylinder-shaped myotubes.
