Semistructured interviews were conducted with 40 adolescents who reported inhaling volatile solvents. Their average age was 14.2 years, and they used a range of substances. All were aware of the short-term health risks involved in volatile solvent use, and most reported experiencing ill effects, such as headaches and vomiting. Users were found to be organized into groups and peer networks, which often were involved in theft, prostitution, and other risk-taking behaviors. More chronic users had higher status within the group. Suggestions pertaining to intervention were obtained, and these are discussed in light of the findings.

The whole plant Saccocalyx satureioides, an endemic medicinal plant in Algeria, was evaluated for its polyphenolic contents, antioxidant and antimicrobial activities. The polyphenolic contents of the plant methanolic extracts ranged from 170.47 to 285.

However, the muscle of farmed exhibits a strong off-flavor, resulting in poor flavor quality. To enhance the flavor quality of the meat, this study examined the volatile compounds in muscle by establishing identification methods for these volatile odor compounds and comparing the differences between the two aquaculture modes.

Background: Sample preparation can be a critical stage of analytical procedures that profoundly influences their performance, environmental impact, and overall efficiency. While nanomaterials have revolutionized sample preparation owing to their high surface area-to-volume ratios, tunable surface chemistry, and enhanced adsorption capacities, limitations persist. Researchers have ushered in a new era of efficient sample preparation methodologies that could overcome the limitations of nanomaterials by introducing deep eutectic solvents (DESs), which have unique advantages such as low volatility and toxicity, biodegradability, and tunability.

This study aimed to investigate β-Caryophyllene (BCA) pharmacokinetics as well as the potential antitumor activity and mechanism of action of BCA and eugenol (EU), alone or in combination, in U87 glioblastoma (GB) cells. The BCA pharmacokinetic was studied by evaluating its concentration profiles in rat blood and cerebrospinal fluid after oral and intravenous administration. EU and BCA antitumor mechanisms were assessed by comparing their effects in U87 GB cells and non-tumoral HMC3 cells.
