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 in control of the activated sludge process

Water Science and Technology, 1996
This paper summarises progress of the IAWQ Task Group developing the Scientific and Technical Report (STR) on respirometry in control of the activated sludge process. The significance of respirometry in activated sludge systems is explained from a biochemical background. A classification is proposed which includes all respirometric measuring principles

Calciprotein particle‐induced calcium overload triggers mitochondrial dysfunction in endothelial cells

The Journal of Physiology, EarlyView.
Abstract figure legend Calciprotein particles (CPPs) are small calcium‐ and phosphate‐containing nanoaggregates associated with the development of vascular disease (CVD) in chronic kidney disease (CKD). Previously, we have shown that CPPs induce endothelial cell (EC) dysfunction, possibly contributing to CVD in CKD, but the underlying molecular ...

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

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Juvenile-specific high heat production contributes to the initial step of endothermic development in Pacific bluefin tuna

Frontiers in Physiology
Pacific bluefin tuna (Thynnus orientalis; PBT) can maintain their body temperature above ambient water (i.e., thermal excess) through high heat production and heat retention.

NAD replenishment restores mitochondrial function and thermogenesis in the brown adipose tissue of mice with obesity

The Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat diet (HFD) induces brown adipose tissue (BAT) whitening, mitochondrial dysfunction (damaged cristae, fragmentation), reduced NAD+ levels and impaired thermogenesis, leading to lower energy expenditure and metabolic inflexibility.

Uncovering the time-temperature thresholds of in vitro mitochondrial bioenergetics dysfunction under hyperthermic stress

International Journal of Hyperthermia
Mitochondrial respiration is particularly vulnerable to temperature fluctuations, yet time-dependent effects of hyperthermia on mitochondria remain largely unexplored.
