Regulation of mTORC1 by growth factors,energy status,amino acids and mechanical stimuli at a g lance
mTORC1 Akt Myostatin Muscle protein synthesis
2016/5/16
The mechanistic/mammalian target of rapamycin c omplex 1 (mTORC1) plays a pivotal r ole in the regulation of skeletal muscle protein synthesis. A ctivation of the c omplex leads to phosphorylation of ...
Dietary energy requirements in relatively healthy maintenance hemodialysis patients estimated from long-term metabolic studies
dietary energy needs chronic kidney disease chronic kidney failure renal nutrition body composition
2018/11/28
Background: Studies that examined dietary energy requirements (DERs) of patients undergoing maintenance hemodialysis (MHD) have shown mixed results. Many studies reported normal DERs, but some describ...
