The association between cardiovascular health and obstructive sleep apnea symptoms: findings from NHANES.

Objective: To investigate the association between cardiovascular health (CVH) and obstructive sleep apnea (OSA) within the U.S. population.

Effects of coexisting goethite or lepidocrocite on Fe(II)-induced ferrihydrite transformation pathways and Cd speciation.

The efficacy of ferrihydrite in remediating Cd-contaminated soil is tightly regulated by Fe(II)-induced mineralogical transformations. Despite the common coexistence of iron minerals such as goethite and lepidocrocite, which can act as templates for secondary mineral formation, the impact of these minerals on Fe(II)-induced ferrihydrite transformation and the associated Cd fate have yet to be elucidated. Herein, we investigated the simultaneous evolution of secondary minerals and Cd speciation during Fe(II)-induced ferrihydrite transformation in the presence of goethite versus lepidocrocite.

The community dynamic alterations mechanisms of traveling plastics in the Pearl River estuary with the salinity influence.

Most ocean plastics originate from terrestrial emissions, and the plastisphere on the plastics would alter during the traveling due to the significant differences in biological communities between freshwater and marine ecosystems. Microorganisms are influenced by the increasing salinity during traveling. To understand the contribution of plastic on the alteration in biological communities of plastisphere during traveling, this study investigated the alterations in microbial communities on plastics during the migration from freshwater to brackish water and saltwater.

Influence of calcium carbonate on ferrihydrite bio-transformation and associated arsenic mobilization/redistribution.

The sulfate-reducing bacteria (SRB)-induced ferrihydrite transformation is an important cause for arsenic (As) contamination in the aquifer near mining area. Calcium carbonate (CaCO) is widespread and has the potential of regulating As fate directly or indirectly. However, the influence of CaCO on ferrihydrite transformation and the associated As mobilization/redistribution in SRB-containing environments remains unclear.
