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

A BODIPY fluorescence probe modulated by selenoxide spirocyclization reaction for peroxynitrite detection and imaging in living cells

, 2013
We present the synthesis, spectroscopic properties, and live-cell application of a new BODIPY (boron dipyrromethene) fluorescence probe BOD-Se based on selenoxide spirocyclization reaction for peroxynitrite detection.

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

The Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

The reactive nitrogen species peroxynitrite is a potent inhibitor of renal Na-K-ATPase activity

, 2008
Peroxynitrite is a reactive nitrogen species produced when nitric oxide and superoxide react. In vivo studies suggest that reactive oxygen species and, perhaps, peroxynitrite can influence Na-K-ATPase func-tion.

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Homogenous catalysis of peroxynitrite conversion to nitrate by diaryl selenide: a theoretical investigation of the reaction mechanism

Frontiers in Chemistry
Quenching peroxynitrite (a reactive oxidant species) is a vital process in biological systems and environmental chemistry as it maintains redox balance and mitigates damaging effects in living cells and the environment.

Pyroptosis in Preeclampsia: Placenta‐to‐Maternal Organ Communication, Molecular Mechanisms, and Therapeutic Targets

Comprehensive Physiology, Volume 16, Issue 6, December 2026.
Schematic diagram illustrating the potential mechanisms and core molecules contributing to the development of PE via mediating pyroptosis: focus on trophoblasts and endothelial cells. Pyroptosis of trophoblast cells in the placenta of preeclampsia not only inhibits its invasion, migration, and differentiation, causing local infiltration and ...

Peroxynitrite stimulates pulmonary artery endothelial and smooth muscle cell proliferation : Involvement of ERK and PKC

, 2011
There is evidence that peroxynitrite is generated in pulmonary hypertension and we have therefore investigated whether peroxynitrite can cause proliferation of pulmonary artery cells.

The Boron–Neuron Connection: The Potential of Boron‐Containing Molecules for Treating Incurable Amyotrophic Lateral Sclerosis

ChemMedChem, Volume 21, Issue 21, 12 November 2026.
Can a single element help address the multifactorial nature of ALS? Boron‐containing compounds combine responsiveness to reactive oxygen species (ROS), neuroprotective activity, and favorable pharmacological properties, offering a distinctive framework for disease modification in a complex disease like ALS.
