Abstract:
:The fluxes of nitroglycerine (NG) through human abdominal epidermis from different individuals were measured in vitro at 32°C. The mean NG flux for the entire group was 16.9 µg/cm(2) × hr, with a standard deviation of 47.7%. There are no significant differences in the means and the variances of NG fluxes between males and females. In groups of different ages (36-58 and >60 years) the mean values are in the same range, whereas the variance is significantly higher in the elderly.

杂志文章abstract:PURPOSE:Proteasome inhibition induces endoplasmic reticulum (ER) stress and compensatory autophagy to relieve ER stress. Disturbance of intracellular calcium homeostasis can lead to ER stress and alter the autophagy process. It has been suggested that inhibition of the proteasome disrupts intracellular calcium homeosta...
