Highlights The protein pyrrole adducts in both plasma and urine correlated well with glucose indices, namely fasting blood glucose (FBG) and glycate hemoglobin A1c (HbA1c). Elevated plasma pyrrole adducts was related to positive distal symmetric polyneuropathy (DSPN) symptoms and a high resting heart rate.

ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

This study reveals a shift in woody plant community assembly from competitive exclusion in early succession to habitat filtering in later stages within karst areas. Environmental distance (80.54%) contributed significantly more than geographical distance (9.95%), providing strong quantitative evidence that niche processes, particularly habitat ...
