Ketone Esters Partially and Selectively Rescue Mitochondrial Bioenergetics After Acute Cervical Spinal Cord Injury in Rats: A Time-Course

Cells
Spinal cord injury (SCI) pathology and pathophysiology can be attributed to both primary physical injury and secondary injury cascades. Secondary injury cascades involve dysregulated metabolism and energetic deficits directly linked to compromised ...

Intraspecific variation in aerobic and anaerobic locomotion: gilthead sea bream (Sparus aurata) and Trinidadian guppy (Poecilia reticulata) do not exhibit a trade-off between maximum sustained swimming speed and minimum cost of transport.

Frontiers in Physiology, 2015
Intraspecific variation and trade-off in aerobic and anaerobic traits remain poorly understood in aquatic locomotion. Using gilthead sea bream (Sparus aurata) and Trinidadian guppy (Poecilia reticulata), both axial swimmers, this study tested four ...

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

Respirometry for determination of the influents SS-concentration

, 1996
A method is presented for determining influent readily biodegradable substrate concentration (SS). The method is based on three different respiration rates, which can be measured with a continuous respiration meter which is operated in a cyclic way ...

Skeletal muscle‐specific myostatin overexpression promotes muscle oxidative capacity and fatigue resistance in transgenic mice

Experimental Physiology, EarlyView.
Abstract In addition to controlling muscle mass, myostatin may support oxidative metabolism and endurance. Loss of function through gene knockout or post‐natal blockade generally lowers muscle oxidative capacity and increases fatigability. These observations imply that myostatin activation could promote a more oxidative and less fatigable muscle ...

Substrate‐specific mitochondrial dysfunction and metabolomic profiles in type 2 diabetic rat hearts

Experimental Physiology, EarlyView.
Abstract Type 2 diabetes (T2D) greatly alters cardiac fuel handling, yet how mitochondrial function adapts to the diabetic substrate environment remains unclear. This study investigated substrate‐specific cardiac mitochondrial bioenergetics from a T2D rat model induced by a high‐fat diet and low‐dose streptozotocin.

Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

The Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Bioenergetic signatures of circulating blood cells as biosensors of metabolic health in food-producing animals

Frontiers in Veterinary Science
The intensification of animal production has substantially increased productivity, yet it has concurrently increased the metabolic vulnerability of livestock and poultry. Traditional biomarkers often lack sensitivity and fail to capture early or systemic
