https://www.selleckchem.com/products/Adrucil(Fluorouracil).html Trace metal contaminants in indoor dust pose a significant potential exposure risk to people because of the time spent indoors and the readily ingested and inhaled fine-grained composition of indoor dusts. However, there is limited trace metal data available on the specific interaction of dust particle size fraction and their respective bioaccessibility/bioavailability and its consequent effect on health risk assessment. This study addresses this knowledge gap by examining bioaccessible and bioavailable trace element concentrations (As, Cr, Cu, Mn, Ni, Pb, Zn) in 152 discrete size fractions from 38 indoor vacuum samples from a larger dataset (n = 376) of indoor dust from Sydney, Australia. Arsenic, Cu, Ni, Pb and Zn were most concentrated in the 90-150 μm fraction with Cr and Mn being more concentrated in 5 μg/dL. Lead concentrations measured in the selected dust samples show a potential for adverse health impacts on young children with the greatest risk being from indoor dust sized 90-150 μm.Bisphenol A (BPA) is a ubiquitous environmental contaminant that is known to be associated with the risk of arterial hypertension. However, the underlying mechanisms describing how BPA exposure leads to high blood pressure (BP) and the role of epigenetics are still unclear. Therefore, we evaluated associations among BPA exposure, microRNA (miRNA) expression, and BP in a randomized crossover trial with 45 non-smoking females over 60 years of age. The participants visited the study site 3 times and were dose-dependently exposed to BPA. Two hours after exposure to BPA, urine and whole blood were collected for BPA measurement and miRNA profiling, and BP was measured. Relationships among urinary BPA level, miRNA expression, and BP were estimated using the mixed effect model. Decreases in miR-30a-5p, miR-580-3p, miR-627-5p, and miR-671-3p and increases in miR-636 and miR-1224-3p attributable to BPA exposure were associat
