Updated reference intervals for serum cystatin C and creatinine based on age and sex variations.

Unlabelled: We investigated inconsistencies between results for cystatin C (Cys C) and creatinine (Crea) in patients undergoing health check-ups. Data from 36,836 individuals who underwent health checkups at Huashan Hospital over the previous 3 years were analyzed. We extracted laboratory results of 10 biomarkers and information on sex and age.

Synthesis of Sulfenamides via Photoredox N-S Coupling of Dialkyl Azodicarboxylates and Thiols.

We herein report a photoredox N-S coupling reaction between dialkyl azodicarboxylates and thiols to access sulfenamide scaffolds. This reaction proceeds under mild, green, and operationally simple conditions, offering a broad scope of sulfenamides with high yields and excellent atom efficiency. Mechanistic investigations revealed this reaction followed a photoinitiated radical pathway in which iodide plays a crucial role as both a radical initiator and a single-electron reductant.
