The Role of Ozone as an Nrf2-Keap1-ARE Activator in the Anti-Microbial Activity and Immunity Modulation of Infected Wounds

open access: yesAntioxidants, 2023
Ozone is an allotrope of oxygen, widely known to exert an anti-oxidant potential. The ability of low, controlled and standardized doses of ozone in the ozone adjunct treatment of bacterial infections, which occur in wounds, is engaging clinical research ...

Stratospheric sink for chlorofluoromethanes: chlorine atomc-atalysed destruction of ozone

open access: yesNature, 1974
Chlorofluoromethanes are being added to the environment in steadily increasing amounts. These compounds are chemically inert and may remain in the atmosphere for 40–150 years, and concentrations can be expected to reach 10 to 30 times present levels ...

Physicochemical characteristics of ozonated sunflower oils obtained by different procedures

open access: yesGrasas y Aceites, 2012
Two ozonation procedures for sunflower oils at different applied ozone dosages were carried out. Ozone was obtained from medicinal oxygen and from air. Peroxide, acidity, and iodine indexes, along with density, viscosity and antimicrobial activity were ...

Ozone pollution in China: A review of concentrations, meteorological influences, chemical precursors, and effects.

open access: yesScience of the Total Environment, 2017
High concentrations of ozone in urban and industrial regions worldwide have long been a major air quality issue. With the rapid increase in fossil fuel consumption in China over the past three decades, the emission of chemical precursors to ozone ...

Recent advances in ozone-based advanced oxidation processes for treatment of wastewater- A review

open access: yes, 2020
The wastewater reclamation is the need of today's world. Advanced oxidation processes (AOPs) are considered as a good option for removing recalcitrant organic materials in wastewater by oxidation reactions with powerful, non-selective hydroxyl radical ...

Inhibitory effects of Spirulina in zymosan-induced arthritis in mice

open access: yesMediators of Inflammation, 2002
The anti-inflammatory effect of microalgae Spirulina was studied in zymosan-induced arthritis in mice. Four days after the intra-articular injection of zymosan (15 mg/ml), Spirulina (100 and 400 mg/kg per-orally) was administered to animals for 8 days ...

Ozone and Ozonated Oils in Skin Diseases: A Review

open access: yesMediators of Inflammation, 2010
Although orthodox medicine has provided a variety of topical anti-infective agents, some of them have become scarcely effective owing to antibiotic- and chemotherapeutic-resistant pathogens. For more than a century, ozone has been known to be an excellent disinfectant that nevertheless had to be used with caution for its oxidizing properties.

Impact of climate variability on tropospheric ozone [PDF]

open access: yes, 2007
A simulation with the climate–chemistry model (CCM) E39/C is presented, which covers both the troposphere and stratosphere dynamics and chemistry during the period 1960 to 1999.

Ozone in biology [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
In this issue of PNAS, Babior et al. (1) extend the published series of experiments by Wentworth et al. (2–5) in which it was shown that antibodies catalyze the generation of ozone by a water oxidation pathway. The overall process is postulated to involve more than one equivalent of the lower-energy singlet state of molecular oxygen (1O2) and to ...
