Mitochondrial capacities and quality control following short‐ and long‐term weight restoration after simulated anorexia nervosa

Experimental Physiology, EarlyView.
Abstract Anorexia nervosa (AN) is a psychiatric disorder characterized by prolonged caloric restriction and skeletal muscle atrophy. Mitochondrial health is a key mediator of muscle function, yet the role of mitochondria during AN and following weight regain has not been investigated. The objective of this study was to evaluate mitochondrial capacities

Quantitative proteomic approaches to studying redox post‐translational modifications in skeletal muscle

Experimental Physiology, EarlyView.
Abstract Reactive oxygen species are essential signalling molecules that regulate numerous aspects of skeletal muscle physiology. These effects are mediated through redox post‐translational modifications on protein cysteine thiols, which influence the structure and function of redox‐sensitive proteins. Mass spectrometry‐based redox proteomic approaches

Putting the brakes on muscle growth: Myostatin as regulator of disuse atrophy

Experimental Physiology, EarlyView.
Abstract Skeletal muscle is a highly plastic tissue that rapidly adapts to changes in mechanical loading and metabolic activity. Periods of inactivity, including bed rest, limb immobilization or microgravity, induce a pronounced loss of muscle mass and function.

Effects of creatine supplementation on lean mass, muscle size and muscle performance during immobilisation and rehabilitation: A systematic review

Experimental Physiology, EarlyView.
Abstract Creatine monohydrate (CrM) supplementation has established benefits in exercising populations; however, its efficacy during disuse and subsequent rehabilitation remains unclear. This systematic review assessed the effects of CrM supplementation on muscle size, lean mass and muscle performance (strength, power, endurance) during periods of ...

The ‘lactate paradox’ revisited after 35 years: In memoriam Paolo Cerretelli

Experimental Physiology, EarlyView.
Abstract Some decades ago significant scientific interest was raised by the concept of the ‘lactate paradox’ occurring during altitude acclimatization. In short, in acute hypoxia blood lactate− concentration ([La]b) is higher, compared to normoxia, at any given submaximal work rate, whereas peak [La]b at exhausting exercise is unchanged.

Regulation of bacterial glycogen synthesis

Molecular and Cellular Biochemistry, 1983
The formation of the alpha 1,4 glucosidic linkages of bacterial glycogen occurs first by synthesis of ADPglucose from ATP and alpha glucose 1-P and then transfer of the glucose moiety from the formed sugar nucleotide to a pre-existing glucan primer.

The control of glycogen synthesis in the liver

Advances in Enzyme Regulation, 1970
Abstract In the liver, glycogen synthetase exists in two forms, one of them (a) active, the other (b) inactive in the ionic conditions which exist in the cell. These two forms are interconvertible, presumably by phosphorylation and desphosphorylation under the action of a specific kinase and phospharylation and respectively, It seems probable that ...

The initiation of glycogen synthesis

BioEssays, 1986
AbstractThe claim that glycogen contains protein was first made exactly 100 years ago and has been the subject of contention ever since. It has now been established that rabbit‐muscle glycogen contains a covalently bound protein of Mr 37,000, present in equimolar proportion to glycogen.
