the present work describes a reverse phase hplc method for the quantitation of drotaverine hydrochloride and mefenamic acid in human plasma. organic solvent system used for liquid extraction composed of dichloromethane, and isopropyl alcohol in the ratio 80:20 (v/v). the compounds were separated on a thermo bds hypersil c8 (25.0 cm×4.6 mm, 5 µm particle size) column in isocratic mode with a mix...

Introduction: Humic acids have adverse effects on the water quality, then should be removed from water resources. The aim of this study was to evaluate the effect of nitrate as a radical scavenger for removal of humic acid from aqueous solutions by electron beam irradiation. Materials and Methods: In this study, after preparation of stock humic acid solution in alkaline condition, different con...

The role of metabolic diseases in ischemic stroke has become a primary concern in both research and clinical practice. Increasing evidence suggests that dysbiosis is associated with metabolic diseases. The aim of this study was to investigate whether the gut microbiota, as well as concentrations of organic acids, the major products of dietary fiber fermentation by the gut microbiota, are altere...

Methods are described to synthesize shape-selectable, monodisperse, aqueous-stable metal-organic frameworks (MOFs) by the reaction of aluminium nitrate with benzene tricarboxylic acid in various aqueous solvent mixtures and acetic acid as the capping ligand. Environmental stability was confirmed by thermal analysis and immersion in aqueous acidic media.

Primary hyperoxaluria (PH) is an autosomal recessive metabolic abnormality characterized by excessive oxalate excretion leading to nephrocalcinosis and progressive renal dysfunction. Type I primary hyperoxaluria (PH I) results from a deficiency of alanine:glyoxylate aminotransferase, whereas type II disease has been traced to a deficiency of D-glycerate dehydrogenase. The two syndromes are ofte...

[1] The Urey in situ organic compound analysis instrument, consisting of a subcritical water extractor (SCWE) and a portable microchip capillary electrophoresis instrument called the Mars Organic Analyzer (MOA), was field tested in the Atacama Desert, Chile, in June 2005. Soil samples from the most arid Yungay region were collected, biomarkers were extracted by the SCWE, and organic amine compo...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

Organic acids are formed in food as a result of metabolism of large molecular mass compounds. These organic acids play an important role in the taste and aroma of fermented food products. Doenjang is a traditional Korean fermented soybean paste product that provides a major source of protein. The quantitative data for volatile and non-volatile organic acid contents of 18 samples of Doenjang wer...

background: outbreak and spread of bacterial infections resulted in increasing use of antibiotics which subsequently leaded to bacterial resistance to conventional antibiotics. objectives: to evaluate the effects of organic acids (selko-ph®), probiotic (primalac®) and echinacea purpurea (ep) alcoholic extract on the immune system of the broiler chickens, a completely randomized design experimen...
