Selenium nanoparticles induce coumarin metabolism and essential oil production in Trachyspermum ammi under future climate CO conditions.

Research on nanoparticles (NPs) and future elevated CO (eCO) is extensive, but the effects of SeNPs on plant growth and secondary metabolism under eCO remain uncertain. In this study, we explored the impact of SeNPs and/or eCO on the growth, physiology, chemical composition (primary metabolites, coumarins, and essential oils), and antioxidant capacity of Trachyspermum (T.) ammi.

Sleep Patterns of Pilots: An Objective Assessment.

Objectives Circadian dysregulation (jetlag), sleep loss (extended wakefulness), sleep deprivation (acute or chronic), fatigue (exhaustion), preexisting medical and mental conditions, and medication use can all affect the cognitive and behavioral performance of commercial aircraft pilots. This study evaluated the sleep habits of pilots and copilots flying short-haul flights in the Gulf region. Methods This cross-sectional study examined Airbus A320 pilots and copilots for one of Saudi Arabia's commercial airlines.

Synergistic effect of carbon nanoparticles with mild salinity for improving chemical composition and antioxidant activities of radish sprouts.

The demand for healthy foods with high functional value has progressively increased. Carbon nanoparticles (CNPs) have a promising application in agriculture including the enhancement of plant growth. However, there are few studies on the interactive effects of CNPs and mild salinity on radish seed sprouting.

Evaluation of environmental and biological monitoring methods for toluene exposure assessment in paint industry.

The aim of this study was to assess the exposure to Toluene in paint industry and to evaluate the environmental and biological monitoring techniques for the assessment of occupational exposure to this aromatic hydrocarbon. In this study, personal active and passive air sampling for toluene measurements, blood and urine sampling respectively for B-Tol and HA or U-Tol analyses for eight workers from two paint and thinner production factories were collected during four successive working days. Correlations were analyzed between biological indicators and environmental toluene exposure levels.

CO Enrichment Differentially Upregulated Sugar, Proline, and Polyamine Metabolism in Young and Old Leaves of Wheat and Sorghum to Mitigate Indium Oxide Nanoparticles Toxicity.

Soil contamination with indium oxide nanoparticles (InO-NPs) is a challenge for plant growth and productivity. Despite InO-NPs toxicity, their effects on plant growth and metabolism are largely unknown, particularly under future climate CO (eCO). Therefore, the InO-NPs toxicity and stress mitigating impact of eCO in the young and old leaves of C3 (wheat) and C4 (sorghum) plants were investigated.
