Measurements of air humidity, temperature, carbon dioxide (CO2), respirable particles, ozone, nitrogen dioxide (NO2), formaldehyde, and volatile organic compounds of possible microbial origin (MVOC) were performed during 26 flights with Boeing 767-300. The mean temperature in cabin was 22.2 °C (range 17.4-26.8 °C), and mean relative air humidity was 6% (range 1-27%). The CO2 during cruises was ...

the objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. one hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...

We describe a new focal ischemia model consisting of unilateral middle cerebral artery occlusion with a silicone rubber cylinder attached to a nylon surgical thread inserted through the internal carotid artery in rats. Recirculation was accomplished by pulling the thread out of the artery. We evaluated the reliability of this model and studied the influence of reperfusion of the brain by measur...

-----------------Previous studies have shown that extracorporeal circulation devices can activate the complement cascade via the alternative pathway. Anaphylatoxins (C3a and C5a) generated by complement activation may lead to pulmonary leukocyte sequestration, pulmonary edema, granulocytopenia and microvascular lung damage. This is of particular concern in patients on cardiopulmonary bypass. Th...

The acute and chronic action of the oxidant gases ozone, nitrogen dioxide and oxygen on the morphological appearance of cells of the alveolar and bronchiolar epithelium is reviewed. Type I cells of the alveolar and ciliated cells of the bronchiolar epithelium appear to be sensitive targets for the oxidant gases. The degree of damage is influenced by age, nutritional status and the development o...

The aim of this work was to investigate effect of operational parameters on the photocatalytic degradation efficiency of a solution containing C. I. Basic Blue 41 BB41 in a recirculated rectangular photoreactor irradiated with a UV light. TiO_2 nano composite film was prepared via sol-gel dip coating method. The films were characterized by X-ray diffraction XRD, transmission electron microscopy...
