The chemistry of peroxynitrite, a biological toxin

Química Nova, 1998
Oxyradicals play a tole in several diseases. While for several decades the hydroxyl radical - produced via the Fenton reaction - has been considered the species that initiates oxyradical damage, new findings suggest that much of this damage can be ...

Cardiac spheroids as promising in vitro models to study the human heart microenvironment

Scientific Reports, 2017
Three-dimensional in vitro cell systems are a promising alternative to animals to study cardiac biology and disease. We have generated three-dimensional in vitro models of the human heart (“cardiac spheroids”, CSs) by co-culturing human primary or iPSC ...

Modification of DNA structure by reactive nitrogen species as a result of 2-methoxyestradiol–induced neuronal nitric oxide synthase uncoupling in metastatic osteosarcoma cells

Redox Biology, 2020
2-methoxyestradiol (2-ME) is a physiological anticancer compound, metabolite of 17β-estradiol. Previously, our group evidenced that from mechanistic point of view one of anticancer mechanisms of action of 2-ME is specific induction and nuclear hijacking ...

A comparative study of the major antimicrobial agents against the yeast cells on the tissue model by helium and air surface micro-discharge plasma

AIP Advances, 2020
Surface micro-discharge (SMD) plasma with a large-area and homogeneous discharge has attracted much attention in the skin disinfection due to its high antimicrobial efficiency and less side effects on tissues.

Comparing thiol and selenol reactivity towards peroxynitrite by computer simulation

Redox Biochemistry and Chemistry
Peroxynitrite is a very reactive species implicated in a variety of pathophysiological cellular processes. Particularly, peroxynitrite-mediated oxidation of cellular thiol-containing compounds such as cysteine residues is a key process which has been ...

Conjugation of nitrated acetaminophen to Der p1 amplifies peripheral blood monocyte response to Der p1.

PLoS ONE, 2017
BACKGROUND:An association of acetaminophen use and asthma was observed in the International Study of Asthma and Allergies in Childhood study. However there are no clear mechanisms to explain an association between acetaminophen use and immunologic ...

Cold Gas Plasma Induces Platelet Activation and Hemostasis in Native and Anticoagulated Human Blood

Advanced NanoBiomed Research, Volume 6, Issue 7, July 2026.
Cold physical gas plasma induces platelet activation and hemostatic responses in native and anticoagulated human blood. Treatment efficacy depends on plasma parameters, including gas composition, distance, and exposure mode, which govern reactive species delivery and energy transfer.

Kinetics of Bacterial Inactivation by Peroxynitric Acid in the Presence of Organic Contaminants

Applied and Environmental Microbiology, 2021
A good disinfectant for the human body should have various properties, such as strong bactericidal activity, harmlessness to living tissues, and resistance against biological fluids (or other organic contaminants). Peroxynitric acid (PNA) showed a bactericidal effect that was several tens up to several hundred times higher per unit of molarity than ...

Escherichia coli Biofilm Inactivation by Plasma‐Activated Water Mist

Journal of Food Safety, Volume 46, Issue 2, April 2026.
Biofilms formed on stainless steel surfaces were treated with plasma‐activated water mist. Later, plasma properties, plasma‐activated water chemistry, and mist particle size and distribution were systematically characterized. The antimicrobial efficacy of plasma‐activated mist against biofilms was evaluated using bacterial enumeration, biomass analysis,
