Competitive adsorption and diffusion of methane and vapor-phase per- and polyfluoroalkyl substances in montmorillonite nano pores: Environmental implications.

Vapor-phase perfluoroalkyl and polyfluoroalkyl substances (PFASs), along with methane emissions from landfills has been key contributors of their atmospheric transport and global distribution. Given the persistence, bioaccumulation, and potential health risks associated with PFAS, understanding their transport behavior in landfill gas barrier is of paramount importance. To gain a deeper understanding of the adsorption and diffusion behavior of vapor-phase PFAS in unsaturated, montmorillonite-rich clay barriers, a molecular dynamics simulation was conducted.

Clinical Phenotypes and Disease-specific Health-related Quality of Life in Patients of Chronic Obstructive Pulmonary Disease.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a common health issue globally and is expected to increase in the future. The latest Global Initiative for COPD (GOLD) guidelines describe the various phenotypes of COPD. This study assessed the different clinical phenotypes and disease-specific health-related quality of life (HRQoL) in patients with COPD.

Prenatal arsenic exposure alters EZH2/H3K27me3 to induce RKIP/NF-kB/ERK1/2-mediated early-onset kidney disease in mouse offspring.

The rising incidences of chronic kidney disease (CKD) and renal failure are a major public health concern. Arsenic, a widespread water contaminant and environmental toxicant, is well-known to contribute to kidney disease in adults. However, its long-term effects on kidney health following early-life exposure remain poorly understood.

Gemella sanguinis: A Rare Cause of Endocarditis in a Bicuspid Aortic Valve.

Here, we present a case of infective endocarditis (IE) caused by a pathogen that rarely causes human infection. The patient in this case was an otherwise healthy 50-year-old man who presented with gradually worsening shortness of breath, weight loss, fatigue, chills, and leg swelling for six weeks. He had no prior history of cardiac disease and had never used intravenous drugs, but he had undergone extensive dental work following a military-associated injury.
