7-Keto-Cholesterol and Cholestan-3beta, 5alpha, 6beta-Triol Induce Eryptosis through Distinct Pathways Leading to NADPH Oxidase and Nitric Oxide Synthase Activation [PDF]
BACKGROUND/AIMS: We showed that patho-physiological concentrations of either 7-keto-cholesterol (7-KC), or cholestane-3beta, 5alpha, 6beta-triol (TRIOL) caused the eryptotic death of human red blood cells (RBC), strictly dependent on the early production

Nitric oxide from inflammatory origin impairs neural stem cell proliferation by inhibiting epidermal growth factor receptor signaling [PDF]
Neuroinflammation is characterized by activation of microglial cells, followed by production of nitric oxide (NO), which may have different outcomes on neurogenesis, favoring or inhibiting this process.

TcI isolates of Trypanosoma cruzi exploit the antioxidant network for enhanced intracellular survival in macrophages and virulence in mice [PDF]
Trypanosoma cruzi species is categorized into six discrete typing units (TcI to TcVI) of which TcI is most abundantly noted in the sylvatic transmission cycle and considered the major cause of human disease. In our study, the TcI strains Colombiana (COL),

The effect of pterin-6-aldehyde (P6A), xanthine oxidase inhibitor and superoxide scavenger, on the production of nitrotyrosine as a footprint of tyrosine nitration by peroxynitrite, was compared with that of uric acid, a peroxynitrite scavenger.

Reformulating Pro-Oxidant Microglia in Neurodegeneration [PDF]
In neurodegenerative diseases, microglia-mediated neuroinflammation and oxidative stress are central events. Recent genome-wide transcriptomic analyses of microglial cells under different disease conditions have uncovered a new subpopulation named ...

100 Years of peroxynitrite chemistry and 11 years of peroxynitrite biochemistry [PDF]
The paper on the unusual properties of a mixture of hydrogen peroxide and nitrous acid by Baeyer and Villiger from 1901 can be regarded as the first report on peroxynitrite. In 1990, Beckman and co-workers suggested that peroxynitrite, formed from the reaction of superoxide with nitrogen monoxide, could be a transient oxidizing species in vivo, a ...

Striatal neuroinflammation promotes parkinsonism in rats [PDF]
The specific role of neuroinflammation in the pathogenesis of Parkinson's disease remains to be fully elucidated. By infusing lipopolysaccharide (LPS) into the striatum, we investigated the effect of neuroinflammation on the dopamine nigrostriatal ...

Analysis of acid-stressed Bacillus cereus reveals a major oxidative response and inactivation-associated radical formation [PDF]
Acid stress resistance of the food-borne human pathogen Bacillus cereus may contribute to its survival in acidic environments, such as encountered in soil, food and the human gastrointestinal tract. The acid stress responses of B.

Abstract Peroxynitrite is the product of the nearly diffusion limited reaction between two free radicals, nitric oxide and superoxide. Peroxynitrite is a relatively long-lived, highly reactive species that can undergo harmful secondary oxidations of key cellular components.
