Predicted Potential for Aquatic Exposure Effects of Per- and Polyfluorinated Alkyl Substances (PFAS) in Pennsylvania's Statewide Network of Streams.

Per- and polyfluoroalkyl substances (PFAS) are contaminants that can lead to adverse health effects in aquatic organisms, including reproductive toxicity and developmental abnormalities. To assess the ecological health risk of PFAS in Pennsylvania stream surface water, we conducted a comprehensive analysis that included both measured and predicted estimates. The potential combined exposure effects of 14 individual PFAS to aquatic biota were estimated using the sum of exposure-activity ratios (ΣEARs) in 280 streams.

Trends in the Epidemiology of Deep Vein Thrombosis and Pulmonary Embolism in Patients Undergoing Surgery.

Objective This study aims to utilize the TriNetX database, a comprehensive global network, to improve our understanding of the frequency, demographic factors, and related comorbidities of surgical patients who develop venous thromboembolism (VTEs) events. Methods The global collaborative network in TriNetX was queried for all cases from January 1, 2017, through December 31, 2023. International Classification for Disease (ICD) diagnosis codes were used to define patient cohorts with deep vein thrombosis (DVT) of the upper or lower extremity or pulmonary embolism (PE).

Cross-ancestral GWAS identifies 29 novel variants across Head and Neck Cancer subsites.

In this multi-ancestry genome-wide association study (GWAS) and fine mapping study of head and neck squamous cell carcinoma (HNSCC) subsites, we analysed 19,073 cases and 38,857 controls and identified 29 independent novel loci. We provide robust evidence that a 3' UTR variant in (rs78378222, T>G) confers a 40% reduction in odds of developing overall HNSCC. We further examine the gene-environment relationship of and variants demonstrating their effects act through both smoking and alcohol use.

Analysis of polyclonal and monoclonal antibody to the influenza virus nucleoprotein in different oligomeric states.

Influenza virus nucleoprotein (NP) is one of the most conserved influenza proteins. Both NP antigen and anti-NP antibodies are used as reagents in influenza diagnostic kits, with applications in both clinical practice, and influenza zoonotic surveillance programs. Despite this, studies on the biochemical basis of NP diagnostic serology and NP epitopes are not as developed as for hemagglutinin (HA), the fast-evolving antigen which has been the critical component of current influenza vaccines.
