Anapyrexia (a regulated decrease in body temperature) is a response to hypoxia that occurs in organisms ranging from protozoans to mammals, but very little is known about the mechanisms involved. Recently, it has been shown that the NO pathway plays a major role in hypoxia-induced anapyrexia. However, very little is known about which of the three different nitric oxide synthase isoforms (neuron...

Background Vegetables play an important role in human nutrition. Nitrate content is a signifi-cant quality criterion to determine characteristic of vegetables. About 80% of nitrate intake in human is from vegetables and fruits. High dietary intake of nitrate is seen as an undesirable be-cause of its association with gastric cancer and infantile methemoglobinemia. Varzeghan, North¬western Iran i...

synthetic lhrha or its superactive analogues stimulate gth release. it shows an overlap in the biological activity of lhrha and gnrh in many teleost species. the aim of the present study was to investigate the effects of lhrha2, metoclopramide and chlorpromazine on hpg axis and plasma levels of ght ii. luteinizing hormone releasing hormone analogue 2 (lhrha2) (3 mg/kg) with dopamine antagonis’s...

The growth and metal uptake of two willow clones (Salix fragilis 'Belgisch Rood' and Salix viminalis 'Aage') was evaluated in a greenhouse pot experiment with six sediment-derived soils with increasing field Cd levels (0.9-41.4 mg kg-1). Metal concentrations of eight elements were measured in roots, stems and leaves and correlated to total and soil water metal concentrations. Dry weight root bi...

The nickel removing by electrocoagulation of Ni(II)-NH3-CO2-SO2-H2O system was studied in a batch reactor 50 L useful volume, with stirring, and two pairs aluminum electrodes. operating parameters were concentration between 255 342 mg L-1, current density 11.0 16.6 mA cm-2, pH 8.34±0.06, mean temperature 58.4±3.9 oC retention time min. maximum removal 99.7 % at specific energy consumption 16.86...
