Associations between serum cystatin C and fall reports in an Elderly population.

Fall is common in the elderly, and chronic kidney disease is considered a major risk factor.

Aggregation-induced enhancement of pyrene-based metal-organic framework as a new electrochemiluminescence emitter for ultrasensitive detection of sulfadimethoxine.

In this study, a signal-on electrochemiluminescence (ECL) aptasensor for ultrasensitive detection of sulfadimethoxine (SDM) was constructed based on a competitive aptamer strategy.
