clinical differential diagnosisthe organic acidemias are important in the differential diagnosis of metabolic and neurologic derangement in the neonate and of new-onset neurologic signs in the older child. a-organic aciduriaseveral disorders, not classified as primary disorders of organic acid metabolism, have a characteristic urinary organic acid profile that suggests the appropriate diagnosis...

campylobacter is known to be one of the most common causes of human intestinal disorders. since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. the effects of probiotic (primalac®), medicinal plant (sangrovit®) and organic acid (selko-ph®) as broiler feed additives on ...

this study was carried out in order to evaluate the changes of nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of leonardite and foliar application of n and k. the experiment was conducted in gorgan university of agricultural sciences and natural resources during 2013- 2014. the experiment was laid out a using split-plot arrangement based ...

Leaching properties of Pb, Cd, Zn, Cu at pH of 2-6 using different inorganic acids (hydrochloric acid, sulfuric acid, nitric acid) and organic acids (acetic acids, citric acid, malic acid, succinic acid) aiming at polluted sediment at downstream of a non-ferrous metal smelting enterprise is discussed. Results showed that leaching concentrations of 4 metals decreased with increasing pH. Among al...

Very strong organic acids (acid groups ionized at pH 3.0) represent a significant portion of the total acidity (4--25%) in samples of organic matter isolated from two lakes, a landfill leachate, and a Krafft mill effluent. On the basis of model compound behavior and established complexation constants, these very strongly acidic groups are predicted to be the key to the formation of strong surfa...
