Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

VIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Amelioration of spinal cord injury in rats by blocking peroxynitrite/calpain activity

BMC Neuroscience, 2018
Background Spinal cord injury (SCI) is one of the leading causes of disability and chronic pain. In SCI-induced pathology, homeostasis of the nitric oxide (NO) metabolome is lost. Major NO metabolites such as S-nitrosoglutathione (GSNO) and peroxynitrite

Reactions of peroxynitrite in the mitochondrial matrix

Free Radical Biology and Medicine, 2000
Superoxide radical (O2-) and nitric oxide (NO) produced at the mitochondrial inner membrane react to form peroxynitrite (ONOO-) in the mitochondrial matrix. Intramitochondrial ONOO- effectively reacts with a few biomolecules according to reaction constants and intramitochondrial concentrations.

Umbilical Cord Blood–Derived Extracellular Vesicles Enhance Neurovascular Regeneration and Improve Erectile Function in a Mouse Model of Bilateral Cavernous Nerve Injury

Andrology, EarlyView.
ABSTRACT Background Erectile dysfunction (ED) secondary to cavernous nerve injury (CNI), such as that occurring after radical prostatectomy, remains a significant clinical challenge, particularly among patients who do not respond to phosphodiesterase Type 5 inhibitors (PDE5i).

Diffusion of peroxynitrite, its precursors, and derived reactive species, and the effect of cell membranes

Redox Biochemistry and Chemistry
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.

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

The Ubiquity of the Reaction of the Labile Iron Pool That Attenuates Peroxynitrite-Dependent Oxidation Intracellularly

Biomolecules
Although the labile iron pool (LIP) biochemical identity remains a topic of debate, it serves as a universal homeostatically regulated and essential cellular iron source.

Nitrostative stress status during seasonal and pdmH1N1 infection in Iraq

Journal of Infection in Developing Countries, 2011
Introduction: Influenza A virus infection is associated with oxidative and nitrosative stress. This study aimed to assess nitrosative stress in pandemic H1N1 (pdmH1N1) and seasonal influenza A infected patients.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
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 ...
