Endocannabinoid Overload [PDF]

Molecular Pharmacology, 2010
The signaling capacity of endogenous cannabinoids ("endocannabinoids") is tightly regulated by degradative enzymes. This Perspective highlights a research article in this issue (p. 996) in which the authors show that genetic disruption of monoacylglycerol lipase (MAGL), the principal degradative enzyme for the endocannabinoid 2-arachidonoylglycerol (2 ...

RELATION BETWEEN LEFT VENTRICULAR UNLOADING DURING ECMO AND DRAINAGE CATHETER SIZE ASSESSED BY MATHEMATICAL MODELING

Acta Polytechnica, 2017
The flow-dependent left ventricle overload is a well-known complication of the veno-arterial extracorporeal membrane oxygenation in a severe cardiogenic shock, which leads to a distension of the left ventricle and, frequently, to a severe pulmonary edema.

Comparative Analysis of Muscle Hypertrophy Models Reveals Divergent Gene Transcription Profiles and Points to Translational Regulation of Muscle Growth through Increased mTOR Signaling

Frontiers in Physiology, 2017
Skeletal muscle mass is a result of the balance between protein breakdown and protein synthesis. It has been shown that multiple conditions of muscle atrophy are characterized by the common regulation of a specific set of genes, termed atrogenes.
