Peroxynitrite is a powerful oxidant formed in vivo in sites where superoxide and nitric oxide coincide. Peroxynitrite is cytotoxic through oxidative modification of target biomolecules that can occur by direct or indirect reactions.

Peroxynitrite is a highly reactive nitrogen species and a potent inducer of apoptosis and necrosis in somatic cells. Peroxynitrite-induced nitrosative stress has emerged as a major cause of impaired sperm function; however, its ability to trigger cell ...

Influence of hyperhomocysteinemia on the cellular redox state - Impact on homocysteine-induced endothelial dysfunction [PDF]
Hyperhomocysteinemia is an independent risk factor for the development of atherosclerosis. An increasing body of evidence has implicated oxidative stress as being contributory to homocysteines deleterious effects on the vasculature.

Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...

Photodynamic inactivation increases cell death rate on persistent Staphylococcus aureus
Persistent bacteria have the ability to survive extended periods of antibiotic stress by entering a metabolically dormant state. This study investigated persistence formation in two S. aureus strains and evaluated the effects of PDI using curcumin. Post‐PDI time‐kill assays conducted after metabolic recovery showed a higher rate of bacterial death ...

Molecular imaging of oxidative stress using an LED-based photoacoustic imaging system. [PDF]
LED-based photoacoustic imaging has practical value in that it is affordable and rugged; however, this technology has largely been confined to anatomic imaging with limited applications into functional or molecular imaging.
