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

Cardiac protection with phosphocreatine: a meta-analysis
Interactive CardioVascular and Thoracic Surgery, 2016 Phosphocreatine (PCr) plays an important role in the energy metabolism of the heart and a decrease in its intracellular concentration results in alteration of myocardium energetics and work. We conducted a meta-analysis of all randomized and matched trials that compared PCr with placebo or standard treatment in patients with coronary artery disease or ...

Postexercise phosphocreatine resynthesis is slowed in multiple sclerosis
, 1994 To determine whether skeletal muscle oxidative metabolism is impaired in multiple sclerosis (MS), 31 phosphorus magnetic resonance spectroscopy was used to measure the rate of intramuscular phosphocreatine (PCr) resynthesis following exercise in MS and ...

Role of the creatine/phosphocreatine system in the regulation of mitochondrial respiration.
, 2000 International audienceThe mechanism of metabolic regulation of mitochondrial respiration in cardiac muscle cells was studied experimentally in the permeabilized heart fibres of mice and by computer modelling in silico.

Phosphocreatine Content of Mammalian Cardiac Muscle.
Experimental Biology and Medicine, 1953 Summary1. “Resting” values for the phosphocreatine content of the ventricles of several mammalian species are reported and an explanation is offered for some of the low values recorded in the literature. The necessary precautions are noted if maximal values are to be obtained. 2.

Experimental Physiology, EarlyView.Abstract The purpose was to test: (1) whether the decline in maximal motor unit (MU) firing rate is an invariable response when maximal voluntary contraction (MVC) torque is reduced following a submaximal muscle fatiguing task; and (2) whether fatigue‐induced slowing of contractile speed and firing rate decline are co‐dependent. Ten participants (three

Neuroprotective mechanisms of creatine occur in the absence of mitochondrial creatine kinase
Neurobiology of Disease, 2004 There is substantial evidence that creatine administration exerts neuroprotective effects both in vitro and in vivo. The precise mechanisms for these neuroprotective effects however are as yet unclear.

A linear model of muscle respiration explains monoexponential phosphocreatine changes
, 1988 Phosphocreatine (PCr) content was measured by phosphorus nuclear magnetic resonance spectroscopy in the gastrocnemius muscles of pentobarbital-anesthetized rats during and after twitch stimulation at rates up to 0.75 Hz. The monoexponential time constant
