Spinal anesthesia: should everyone receive a urinary catheter?
Patients undergoing total hip arthroplasty under spinal anesthesia appear to be at low risk for urinary retention. Thus, a routine indwelling catheter is not required for such patients.
Our findings establish that differential checkpoint activation contributes to acquisition of distinct cell cycle duration in two-cell-stage C. elegans embryos and suggest a novel mechanism coupling asymmetric division to acquisition of distinct cell cycle duration during development.
