Apnoea as a novel method to improve exercise performance: A current state of the literature

open access: yesExperimental Physiology, EarlyView.
Abstract Acute breath‐holding (apnoea) induces a spleen contraction leading to a transient increase in haemoglobin concentration. Additionally, the apnoea‐induced hypoxia has been shown to lead to an increase in erythropoietin concentration up to 5 h after acute breath‐holding, suggesting long‐term haemoglobin enhancement.

Exercise responses to perceptually regulated high intensity interval exercise with continuous and intermittent hypoxia in inactive overweight individuals

open access: yesExperimental Physiology, EarlyView.
Abstract To investigate the acute effects of hypoxia applied during discrete work and recovery phases of a perceptually regulated, high‐intensity interval exercise (HIIE) on external and internal loads in inactive overweight individuals. On separate days, 18 inactive overweight (28.7 ± 3.3 kg m−2; 31 ± 8 years) men and women completed a cycling HIIE ...

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

open access: yesThe 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).

Influence of opioids on activity of enzymes in kidneys at no-induced apoptosis

open access: yesRUDN Journal of Medicine, 2009
The influence of dalarginum on activity of enzymes SOD and LDG in cells of a kidney is investigated at the production of nitric oxide. In experiment the infringement of enzymes activity is installed: the activation of anaerobic glycolysis and oppression ...

Heterogeneous metabolic response of endothelial cells from different vascular beds to experimental hyperglycaemia and metformin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Diabetes mellitus is associated with vascular pathology that leads to vascular complications in several tissues, such as retinopathy of the eye. Endothelial dysfunction plays a pivotal role in the progression of each complication.

Enhanced detection of glutamate via transverse relaxation encoding with narrowband decoupling in the human brain

open access: yesMagnetic Resonance in Medicine, Volume 93, Issue 6, Page 2278-2286, June 2025.
Abstract Purpose This study aims to improve the detection of glutamate (Glu) concentration and T2 using an enhanced transverse relaxation encoding with narrowband decoupling (TREND) technique. Methods A new editing pulse was designed to simultaneously invert both Glu H3 spins (2.12 ppm and 2.05 ppm) while minimizing the excitation of Glu H4 ...
