Background: Studies have reported the beneficial effects of exercise, ozone therapy, and stem cell therapy for the treatment of knee osteoarthritis.  Objectives: To reduce the duration of the treatment, we decided to investigate the synergistic effects of Endurance Training (ET), ozone therapy, and mesenchymal stem cell (MSCs) therapy separately or in combination on the cannabinoid receptors 1...

BACKGROUND Ozone concentrations are predicted to increase over the next 50 years due to global warming and the increased release of precursor chemicals. It is therefore urgent that good, reliable biomarkers are available to quantify the toxicity of this pollutant gas at the population level. Such a biomarker would need to be easily performed, reproducible, economically viable, and reflective of...

The effects on heart rate variability (HRV) and arterial stiffness from exposure to ambient particulate matter and ozone have not been studied simultaneously. The aim of this study was to analyze these effects with refined exposure estimates from personal measurements of ozone and size-resolved particulate matter mass concentrations. The authors recruited 17 mail carriers in a panel study in Ta...

INTRODUCTION Chronic exposure to high levels of ozone induces emphysema and chronic inflammation in mice. We determined the recovery from ozone-induced injury and whether an antioxidant, N-acetylcysteine (NAC), could prevent or reverse the lung damage. METHODS Mice were exposed to ozone (2.5 ppm, 3 hours/12 exposures, over 6 weeks) and studied 24 hours (24h) or 6 weeks (6W) later. Nac (100 mg...

The results presented in this paper allow for the estimation of the monthly UV exposure of the human facial region at various locations across the earth. The technique allows a graphical representation of the UV exposures over the face. The erythemal UV exposures as well as the vitamin D exposures to the human facial region have been investigated. The results gained in this paper, for a clear s...

Abstract Climate change will have complex consequences for the environment, society, economy and people’s health. The issue of climate has received comparatively little attention to date in fields sports science. Thus, sport-related health risks caused by are discussed summarized a conceptual model presented here first time. is associated with following increases health-related athletes particu...

This paper examines the ozone (O3) damages caused by nitrogen oxides (NO(x)) emissions in different locations around the Atlanta metropolitan area during a summer month. We calculate O3 impacts using a new integrated assessment model that links pollution emissions to their chemical transformation, transport, population exposures, and effects on human health. We find that increased NO(x) emissio...

Upper airway irritation and airflow limitation have been reported in mice during single exposures to the oxidation products (OPs) of isoprene, a hemiterpene emitted by humans and vegetation. This study evaluated the respiratory effects of repeated exposures to isoprene OPs. Male mice of 6 strains were exposed to a reaction mixture comprised of 3227 ± 157 ppm isoprene and 1080 ± 155 ppm ozone 3 ...

To test the hypothesis that adaptation protecting against acute effects of ambient ozone (O3) exposures develops in Los Angeles residents, human volunteers were exposed to 0.4 ppm O3 under conditions simulating ambient pollution exposures. Blood biochemical, pulmonary physiological, and clinical responses were assessed. Los Angeles residents (N = 6) showed only minimal clinical or physiological...
