is an endemic plant of Kazakhstan of which phytochemical analysis has not been reported. The present study found out that this species enriched with antioxidant chemicals. Isolation and structural identification processes reveal twelve phenolic compounds (-) having dihydroflavanonol, flavonol, isoflavone and flavanol skeletons. The annotation of individual components in the extract was carried out by LC-ESI-MS/MS to represent a chemotaxonomic marker of the target plant. The antioxidant activities of all compounds were screened using three different radical sources (DPPH, ORAC, and hydroxyl radicals). Most compounds (-) had significant antioxidant activity against three radical sources, and their efficacies were found to differ by their functionality and skeleton. The potential of the isolated compounds in preventing oxidative damage of DNA was evaluated with pBR322 plasmid DNA. Compounds (, , , and ) had protective effects on DNA damaged with 80% efficacy at 60 μM concentration.

Potential antihyperlipidemic effects of myrcenol and curzerene in high-fat fed rats.
BMC Pharmacol Toxicol
January 2025
Evangelical College, N'Djamena, BP 1200, Chad.
The study evaluated the anti-hyperlipidemic effects of myrcenol and curzerene on a high fat diet induced hyperlipidemia rat model. Thirty male albino rats were fed on a high-fat diet for four months. The HFD-induced hyperperlipidemia rats were treated with rosuvastatin (10 mg/kg), curzerene (130 mg/kg) and myrcenol (100 mg/kg) for four weeks.

Background: Diabetes mellitus (DM) poses a major risk to human health due to an array of implications, one of which is a detrimental effect on the testicular and reproductive functions. Euphorbia heterophylla is widely recognized for its medicinal properties worldwide.
Methods And Findings: The objective of this study was to profile E.
Thymoquinone-PLGA-PF68 Nanoparticles Induce S Phase Cell Cycle Arrest and Apoptosis, Leading to the Inhibition of Migration and Colony Formation in Tamoxifen-Resistant Breast Cancer Cells.

Department of Biomedical Sciences, Advanced Medical and Dental Institute, Universiti Sains Malaysia, Bertam, Kepala Batas 13200, Penang, Malaysia.
Background: A biocompatible polymeric nanoparticle, TQ-PLGA-PF68, was developed through the interaction of the phytochemical thymoquinone (TQ) encapsulated in poly(L-lactide-co-glycolide)-b-poly(ethylene glycol) (PLGA-PEG) with Pluronics F68. So far, this combination has not been assessed on breast cancer cells resistant to anti-cancer drugs. Therefore, this study aimed to assess the cell death caused by TQ-PLGA-PF68 nanoparticles, particularly in resistant breast cancer cell lines expressing estrogen receptor (ER) positivity, such as TamR MCF-7.

For understanding the toxic action of volatile sulphides, we have evaluated the insecticidal efficacy of sulphide mixture (diallyldisulfide, diallylsulfide and diallyltrisulfide) against F. adults by fumigant toxicity (FT) and contact toxicity (CT) bioassays. Further, diffusional characteristics of sulphides inside the treatment vials were analysed by GC-FPD and microstructural impacts on treated beetles were observed using SEM.

The widespread reliance on single-use plastics (SUPs) has fostered a global throwaway culture, especially in the food packaging industry, where convenience and low cost have driven their adoption, posing serious environmental threats, particularly to marine ecosystems and biodiversity. Edible and ecofriendly packaging made from millet, specifically sorghum ( () Moench), is a promising solution to mitigate SUP consumption and promote sustainability. This study explores the development of edible sorghum bowls, enhanced through roasting and incorporating 3 g of hibiscus and rose flower powders.
