Comparative effects of a glucose–fructose bar, glucose–fructose hydrogel and maltodextrin gel on carbohydrate oxidation and sprint performance in Tier 2 athletes

Experimental Physiology, EarlyView.
Abstract Carbohydrate supplementation optimises athletic performance, but the metabolic and performance impacts of commercial products/compositions are underexplored. We compared the efficacy of three commercial carbohydrate supplements: a glucose–fructose bar (GF‐Bar), a glucose–fructose hydrogel (GF‐Gel) and a maltodextrin‐based gel (MD‐Gel ...

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

Junctional conductance of retinal AII amacrine cell electrical synapses is decreased by NMDA receptors

The Journal of Physiology, EarlyView.
Abstract figure legend AII amacrine cells are an important class of interneuron in the vertebrate retina. In addition to traditional chemical synapses these cells communicate with other neurons and with each other via electrical synapses. (A) Electrical synapse strength between AII amacrine cells was measured using dual whole‐cell patch‐clamp ...

Transport‐related effects on intrinsic and synaptic properties of human cortical neurons: A comparative study

The Journal of Physiology, EarlyView.
Abstract figure legend In this study, we investigated how transporting brain slices influences the electrophysiological and morphological properties of human cortical neurons. Whole‐cell patch‐clamp recordings were obtained from acute slices prepared from tissue collected during epilepsy or tumor surgeries, either on‐site or off‐site, after ...

Bradykinin improves postischaemic recovery in the rat heart: role of high energy phosphates, nitric oxide, and prostacyclin [PDF]

, 2017
Objective: The aim was to define: (1) whether bradykinin administration during reperfusion improves postischaemic myocardial recovery; (2) whether high energy phosphate compounds are involved in the protective effects of bradykinin; and (3) whether ...

Mitochondrial haplotype and sex modulate responses to endurance exercise training

The Journal of Physiology, EarlyView.
Abstract figure legend Using OKC‐HETB/W rats we demonstrate that mitochondrial haplotype influences training responses of endurance exercise. Overall OKC‐HETW rats showed greater responses than OKC‐HETB in exercise tolerance, mitochondrial bioenergetics, mitochondrial DNA (mtDNA) mutation frequencies and motor co‐ordination.

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.
