To investigate changes in blood pressure, lipids, sugar and haematological markers of inflammation associated with long-term exposure to ambient air pollutants.We conducted secondary analyses data on pressure biochemistry from the Social Environment Biomarkers Aging Study Taiwan pollution Environmental Protection Administration 2000. Associations 1-year averaged criteria pollutants (particulate matter aerodynamic diameters <10 μm (PM(10)) <2.5 (PM(2.5)), ozone (O(3)), nitrogen dioxide...

The toxicological effects of zinc oxide nanoparticles (ZnO-NPs) are attracting increasing concern as the field nanotechnology progresses. Although literature suggests that toxicity ZnO-NPs may be related to their dissolution, mechanism for ZnO-NP perturbation cytosolic concentration ([Zn2+]c) homeostasis remains obscure. Using FluoZin-3 and RhodZin-3, this study investigated changes in both [Zn2+]c mitochondrial free Zn2+ ([Zn2+]m) under conditions treatment vivo vitro. In human leukemia...

BackgroundLittle is known about the global magnitude of mesothelioma. In particular, many developing countries, including some with extensive historical use asbestos, do not report mesothelioma.ObjectivesWe estimated mesothelioma accounting for reported and unreported cases.MethodsFor all countries available data on frequency asbestos (n = 56), we calculated 15-year cumulative number mesotheliomas during 1994–2008 from fewer years assessed its relationship levels 1920–1970. We used this to...

Objective: To investigate changes in blood pressure, lipids, and sugar associated with exposure to ambient air pollution. Methods: We conducted secondary analyses of pressure biochemistry markers from Taiwanese Survey on Prevalence Hyperglycemia, Hyperlipidemia, Hypertension pollution monitoring data 2002 by applying generalized additive models. Results: observed increased particulate matter aerodynamic diameters <10 μm was elevated systolic (an interquartile range, 34 μg/m3, for 0.47 mmHg;...

To examine the correlations between long working hours, physical activity, and burnout.A cross-sectional survey was administered to 1560 full-time employees, who underwent periodic health examinations in year 2013. The subjects were divided into upper, middle, lower tertiles according Copenhagen Burnout Inventory (CBI) score.The comparison of high- low-burnout groups revealed that hours significantly correlated with burnout a dose-dependent manner. Long more associated among individuals...

Exposure to zinc oxide (ZnO) metal fumes is linked adverse human health effects; however, the hazards of ZnO nanoparticles (ZnONPs) remain unclear. To determine pulmonary exposure occupationally relevant ZnONPs cause cardiopulmonary injury, Sprague-Dawley rats were exposed via intratracheal (IT) instillation and inhalation. The relationship between intrapulmonary levels oxidative-inflammatory responses 72 h after ZnONP was determined in bronchoalveolar lavage fluid (BALF). Instilled altered...

The total surface area is known to be an effective exposure metric for predicting the lung toxicity of low solubility nanoparticles (NPs). However, if NPs are dissolved quickly enough in lungs, mass may correlated with toxicity. Recent studies have found that zinc oxide (ZnO) was caused by release ions. Thus, we hypothesized could used as ZnO NPs. Healthy Sprague-Dawley rats were exposed a low, moderate, or high dose 35 and 250 nm particles filtered air. Bronchoalveolar lavage fluid...

Background Particulate matter (PM) has been associated with increased pulmonary and cardiovascular mortality morbidity. Additionally, PM is known to exacerbate asthma. However, whether ambient exposure contributes the onset of asthma, especially in non-atopic children adults, less conclusive. The current study aimed evaluate effects size-fractioned on lung immune responses healthy BALB/c mice. Methods principal findings We collected PM10, PM2.5, PM1 PM0.1 samples from October 2012 August...

Effects of air pollution on neurotoxicity and behavioral alterations have been reported. The objective this study was to investigate the pathophysiology caused by particulate matter (PM) in brain. We examined effects traffic-related with an aerodynamic diameter < 1 μm (PM1), high-efficiency (HEPA)-filtered air, clean brain structure, changes, brainwaves, bioreactivity (cortex, cerebellum, hippocampus), olfactory bulb, serum after 3 6 months whole-body exposure 6-month-old Sprague Dawley...
