Fine particulate matter has been linked with acute coronary syndrome. Nevertheless, the key constituents remain unclear. Here, we conduct a nationwide case-crossover study in China during 2015-2021 to quantify the associations between fine particulate matter constituents (organic matter, black carbon, nitrate, sulfate, and ammonium) and acute coronary syndrome, and to identify the critical contributors.

The COVID-19 lockdown created a unique opportunity to study the impact of reduced human activities on water quality. This study aimed to explore how changes in human activities, specifically reduced traffic emissions, influenced water quality in the San Francisco Bay Area from 2019 to 2021. Using chlorophyll-a (Chl-a) concentration as an indicator of water quality and NO₂ concentration as a proxy for traffic emissions, we analyzed the effects of reduced emissions on water quality across different regions of the Bay.

Zaltoprofen (ZAL) is a non-steroidal anti-inflammatory drug (NSAID) with a short half-life (∼2.8 h) due to extensive first pass metabolism. In this context, 16 different polymeric film forming solutions (PFFS) of ZAL were developed using different grades of Eudragits, Polyvinylpyrrolidones, Kollicoat MAE 100 P and Hydroxypropyl cellulose as film formers, and polyethylene glycol 400 as a plasticizer in equal parts of ethanol and isopropyl alcohol used as solvents.

Objective: Alzheimer's disease (AD) and frontotemporal dementia (FTD) are prevalent neurodegenerative diseases characterized by altered brain functional connectivity (FC), affecting over 100 million people worldwide. This study aims to identify distinct FC patterns as potential biomarkers for differential diagnosis.
Methods: Resting-state EEG data from 36 AD patients, 23 FTD patients, and 29 healthy controls were analyzed using time-frequency and bandpass filtering FC metrics.
