[Palm oil and cardiovascular health: considerations to evaluate the literature critically].

Palm oil is obtained from Elaeis guineensis, E. oleifera or the hybrid OxG palm fruits. When crude, it contains high carotenoid concentrations (responsible for the red color), tocopherols and tocotrienols, but most of them are eliminated during its refining.

A single day of bed rest, irrespective of energy balance, does not affect skeletal muscle gene expression or insulin sensitivity.

New Findings: What is the central question of this study? What are the initial metabolic and molecular events that underpin bed rest-induced skeletal muscle deconditioning, and what is the contribution of energy balance? What is the main finding and its importance? A single day of bed rest, irrespective of energy balance, did not lead to overt changes in skeletal muscle gene expression or insulin sensitivity. More than 1 day of physical inactivity is required to observe the insulin resistance and robust skeletal muscle transcriptional responses associated with bed rest and consequent alterations in energy balance.

Abstract: The initial metabolic and molecular events that underpin disuse-induced skeletal muscle deconditioning, and the contribution of energy balance, remain to be investigated.
