The effects of anesthetics on tumor progression.
More and more cancer patients receive surgery and chronic pain control. Cell-mediated immunosuppression from surgical stress renders perioperative period a vulnerable period for tumor metastasis. Retrospective studies suggest that regional anesthesia reduces the risk of tumor metastasis and recurrence. This benefit may be due to the attenuation of immunosuppression by regional anesthesia. On th...

Rear-end collision accidents refer to the part of the accidents due to driver inattention or slow reaction. The aim of this study was to determine the effect of dynamic flashing brake lights (7 Hz) on drivers' brake reaction time using the driv...
متن کاملCellular Reprogramming: Chromatin Puts On the Brake
Directed reprogramming of differentiated cells allows the generation of specific cell types for therapeutics and can provide unexpected insights into development. A recent study demonstrates that efficient reprogramming of Caenorhabditis elegans germ cells into neurons can be achieved by knocking down a histone chaperone gene and ectopic expression of a terminal selector transcription factor.
