BACKGROUND [(11)C]-3-amino-4-(2-dimethylaminomethyl-phenylsulfanyl)-benzonitrile ([(11)C]DASB) is currently the mostly used radiotracer for positron emission tomography (PET) quantitative studies of the serotonin transporter (SERT) in the human brain but has never been validated in dogs. The first objective was therefore to evaluate normal [(11)C]DASB distribution in different brain regions of ...

background: organophosphorus pesticides are one of the most consumable poisons. such poisons can enter water sources by different routes. since consuming some drinking water containing an amount of poison higher than the standard level, causes undesirable effects on human health. this research aimed to study the effectiveness of elimi­nating malathion from water by ultraviolet irradiation (uv) ...

Blood pres sure was 60/40 mm Hg in the right arm. Bilateral crepitant rales were present over both lungs. No heart murmur was audible; 82 was split. An electro cardiogram revealed right ventricular predominance w...

Free uroporphyrin is decarboxylated by heating in the air to 150--200 degrees C. Complete decarboxylation occurs after heating to 200 degrees C for 5 min, with a yield of 66--75%. Heptacarboxylic porphyrin can be prepared with a yield of 40% by heating uroporphyrin to 150 degrees C for 60 min, and hexacarboxylic porphyrin with a yield of about 20% by heating to 150 degrees C for 2h.

Declining hearing sensitivity is appreciated as a normal age related change. However, studies reveal that health variables other than age play significant role in hearing impairment over time. Hypertension is one such variable. The objective of this study was to assess whether the hypertension has an accelerating effect on age related reduction in hearing function in males in the age group of 4...

In this paper, the mechanism of separation volatile organic compounds (VOCs) from activated carbon adsorption beds during closed cycle temperature swing desorption was studied. Toluene gas at different concentrations used as for to regenerate saturated with toluene. This research advances our understanding contaminants and process by which waste a background concentration desorbs in hot concent...

In this work, titanium oxide nanotubes (TNTs) were formed by anodic oxidation on the surface of a Ti–6Al–4V alloy. An electrolyte based ethylene glycol (EG) and ammonium fluoride (NH4F) was used. Different anodizing periods (10, 20, 30, 40, 50, 60 min) with constant potential V established. The morphology TNT array observed scanning electron microscopy (SEM). adhesion strength TNTs to evaluated...
