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.

The stratospheric abundance of peroxynitric acid

Geophysical Research Letters, 1977
A recent re‐examination of the kinetics of the reaction of NO2 with HO2 shows this to be a three body reaction leading to the formation of peroxynitric acid (HO2NO2). The rate of formation is such that significant concentrations of HO2NO2 (not previously included in atmospheric models) are expected to form in the stratosphere.

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 ...

Therapeutic Potential of Melatonin in Gastrointestinal Cancers: Molecular Mechanisms, Preclinical Evidence and Clinical Implications

Journal of Pineal Research, Volume 78, Issue 1, January 2026.
ABSTRACT Gastrointestinal (GI) cancers remain a leading cause of global morbidity and mortality, necessitating novel therapeutic strategies. Melatonin (MEL), an indoleamine with pleiotropic biological activities, has emerged as a promising adjuvant in oncology due to its antiproliferative, proapoptotic, and antioxidant properties.

Enhancing Microbial Safety and Nutritional Quality of Fresh Carrot Juice: Insights From Plasma Jet and Spark Plasma Discharge (SPD) Treatments

Journal of Food Quality, Volume 2026, Issue 1, 2026.
Background The food industry is gaining interest in nonthermal processing methods as an alternative to conventional pasteurization. In addition to preserving nutrition and sensory qualities, pulsed spark discharge (PSD) and plasma jet treatments have shown potential for microbial decontamination.

Reaction of peroxynitrite with thiols, hydrogen sulfide and persulfides

Redox Biochemistry and Chemistry
Three decades of research on the biochemistry of peroxynitrite (ONOOH/ONOO−) have established that this stealthy oxidant is formed in biological systems, and that its main targets are carbon dioxide (CO2), metalloproteins and thiols (RSH).

Evaluation of the Ochratoxin A Reduction and Physicochemical Properties of Green Coffee Beans Following Atmospheric Nonthermal Plasma and Plasma‐Activated Water Treatments

eFood, Volume 6, Issue 2, April 2025.
This study demonstrated that a combined treatment using plasma‐activated water (PAW) and nonthermal plasma (NTP) achieved the highest ochratoxin A reduction in green coffee beans, with up to 51.80% removal, compared to individual treatments. Notably, this combined approach preserved bean quality, showing minimal impact on color, phenolic content, and ...

Photodissociation of Peroxynitric Acid in the Near-IR

The Journal of Physical Chemistry A, 2002
Temperature-dependent near-IR photodissociation spectra were obtained for several vibrational overtone transitions of peroxynitric acid (HNO4) with a tunable OPO photolysis/OH laser-induced-fluorescence system. Band-integrated photodissociation cross-sections ( ∫σdiss), determined relative to that for the 3ν1 OH stretching overtone, were measured for ...
