BACKGROUND The basis for progressive attenuation of the effects of organic nitrates during long-term therapy (nitrate tolerance) remains controversial; proposed mechanisms include impaired nitrate bioconversion resulting in decreased release of nitric oxide (NO) from nitrates and/or increased NO clearance through a reaction with incrementally generated superoxide (O(2)(-)). METHODS AND RESULT...

In this research iron manganese oxide nanocomposites were prepared by co-precipitation, sol-gel and mechanochemical methods by using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared in the presence of various catalyst beds. The polyvinyl pyrrolidon (PVP) was used as a capping agent to control the agglomeration of the nano...

this experiment was conducted to evaluate of different levels of water nitrate on performance and blood parameter of broiler chicks. 240 day old ross 308 were assigned in 5 treatments, 4 replicates and 12 chicks per replicate in a completely randomized design. treatments so that water nitrate concentration was 10 mg in drinking water of poultry farm (control group or cg) and another treatment 4...

In the present work, the extraction of zinc from a sphalerite concentrate using sodium nitrate as an oxidant in a sulfuric acid solution was investigated. The effective parameters such as the temperature, sulfuric acid and sodium nitrite concentrations, stirring speed, particle size, and solid/liquid (S/L) ratio were analyzed. The dissolution rate increased with increase in the sulfuric acid an...

We thank Kruszelnicka and Surdacki (1) for their insightful comments on our recent article (2), which suggested a favorable metabolic effect of endothelial nitric oxide (NO) that stimulates the polarization of hepatic resident macrophages toward an anti-inflammatory M2 phenotype. Kruszelnicka and Surdacki ask whether the nitrate-nitrite pathway exerts beneficial metabolic effects in the liver. ...

An environmentally clean synthesis technique is reported for preparing the green phosphor SrGa2S4:Eu . This method is based on solid state chemical reactions with the use of raw materials: sodium dimethyldithiocarbomate, tetramethylammonium chloride, gallium nitrate, europium nitrate, strontium sulfide and sulfur. The method is shown to produce powders with quasispherical shape, smooth surface ...
