Previous observational studies have shown that the prevalence of cardiovascular diseases (CVDs) is related to particulate matter (PM). However, given methodological limitations conventional research, it difficult identify causality conclusively. To explore PM on CVDs and biomarkers, we conducted a Mendelian randomization (MR) analysis.In this study, obtained summary-level data for biomarkers including atrial fibrillation (AF), heart failure (HF), myocardial infarction (MI), ischemic stroke...

Abstract BACKGROUND Carbon dioxide is not only a major greenhouse gas but also an important carbon resource, which abundant, renewable, low cost and non‐toxic. The coupling reaction of CO 2 with epoxides has shown great potential in the field chemical fixation due to its 100% atomic utilization efficiency. Deep eutectic solvents (DESs) based on tetrabutylammonium bromide (TBAB) were evaluated for cycloaddition propylene oxide (PO) carbonate (PC). Density functional theory (DFT) was used...
