INTRODUCTION Air pollutant exposure has been associated with an increase in inflammatory markers and a decline in lung function in asthmatic children. Several studies suggest that dietary intake of fruits and vegetables might modify the adverse effect of air pollutants. METHODS A total of 158 asthmatic children recruited at the Children's Hospital of Mexico and 50 non-asthmatic children were ...

Polynuclear or polycyclic aromatic hydrocarbons (PAH) are known to be one of the most dangerous hydrocarbons due to their carcinogenic potential. Some PAH have been measured and regulated in the atmosphere to quantify the air quality. However, in order to better understand the presence of these compounds in the atmosphere, it is also important to study the PAH sources. In this paper, the partic...

BACKGROUND Fish and meat intake may affect gestational weight gain, body composition and serum fatty acids. We aimed to determine whether a longitudinal dietary intervention during pregnancy could increase fish intake, affect serum phospholipid fatty acids, gestational weight gain and body composition changes during pregnancy in women of normal weight participating in the Pregnancy Obesity Nutr...

High sodium intake (HNa) increases brain ouabainlike activity (OLA) in rats. In spontaneously hypertensive rats (SHR), HNa exaggerates development of hypertension and pressor and sympathoexcitatory responses to stress. To investigate whether dietary sodium-induced changes in brain OLA play a functional role, responses of mean arterial pressure (MAP), heart rate (HR), and renal sympathetic nerve...

During the development of stealth fighter, S-shaped inlet enters designer’s vision because it has better than bump and straight inlet. use inlet, due to its structural reasons, secondary flow is likely occur in curved section, which directly causes state be changeable complicated. Therefore, this paper takes as research object analyzes steady field simulation under uniform condition distortion ...

BACKGROUND The results of studies on the effect of nutrition on respiratory diseases are inconsistent. The role of nutrition in children's respiratory health was therefore analysed within the cross sectional Central European Study on Air Pollution and Respiratory Health (CESAR). METHOD A total of 20 271 children aged 7-11 were surveyed in six European countries. Respiratory health and food in...

Ultrasonic Sensors in Air are Intelligent Sensors, which use wave-propagation phenomena in air to measure physical or chemical variables. With accordance to the influence principle, two main types of ultrasonic sensors can be differentiated. Propagation-Pafh Sensors decode changes on propagation to get a fast measurement of temperature, pressure variations or gas concentration. Most important a...

Emissions from modern SI-engines are reduced by a three way catalyst. However if there are leaks in the exhaust system before the catalyst emissions increase for two reasons. First the untreated emissions leak out. Second which is worse, due to waves in the exhaust system, oxygen leaks into the manifold and causes an oxygen sensor offset. The result is increased emissions as the air/fuel contro...
