Volatile sulfur compounds (VSCs) are prevalent human biogases detectable in individuals with periodontal disease; therefore, measuring VSC gases in human breath can yield significant, noninvasive diagnostic information indicative of such diseases. In this study, we developed a gas sensor with selective and enhanced sensing capabilities for VSCs methyl mercaptan and hydrogen sulfide. This sensor comprises a cellulose paper substrate impregnated with 2,2'-dithiobis(5-nitropyridine) and sodium acetate.

Background: The incidence of epilepsy increases with age, especially in people diagnosed with dementia. Seizures in an elderly population are likely to have a focal onset, for which sodium channel blockers are the drug of choice. This study reviews the clinical needs and care of people with epilepsy (PWE) in a city wide care home service and assessing the impact of a GP with Special Interest in epilepsy (GPwSIe).

Closed-loop transformation of raw materials into high-value-added products is highly desired for the sustainable development of the society but is seldom achieved. Here, a low-cost, solvent-free and "zero-waste" mechanochemical protocol is reported for the large-scale preparation of cathode materials for sodium-ion batteries (SIBs). This process ensures full utilization of raw materials, effectively reduces water consumption, and simplifies the operating process.

Background: Pesticides are widely used in agriculture to control pests and enhance crop yields. However, post-harvest, there are growing concerns about the potential health risks posed by pesticide residues on produce surfaces. Analyzing these residues is challenging due to their typically low concentrations and the potential interference from the complex matrix of the produce's surface.

Soil microbial communities are particularly sensitive to selenium contamination, which has seriously affected the stability of soil ecological environment and function. In this study, we applied high-throughput 16S rRNA gene sequencing to examine the effects of low and high doses of sodium selenite and the selenite-degrading bacterium, PM1, on soil bacterial community composition, diversity, and assembly processes under controlled laboratory conditions. Our results indicated that sodium selenite and strain PM1 were key predictors of bacterial community structure in selenium-contaminated soils.
