In this research, food-grade aluminum foil (FGAF), rice husk silica (RHS), and sodium hydroxide were needed to synthesize hydroxy-sodalite (HS) using hydrothermal method. The raw materials exposed crystallization at 100 °C for 72, 96 120 h, followed by calcination 6 h 550 °C. products obtained identified X-ray diffraction (XRD) scanning electron microscope (SEM) technique, it applied as catalys...
In previous communications (l-4) the properties and isolation of the l-amino acid oxidase of rat kidney were described. Quite accidentally, it was found that solutions of the enzyme were able to catalyze the oxidation of Z-hydroxy acids, and further study disclosed that this ability ran parallel with l-amino acid oxidase activity from the first crude extract to the final electrophoretically hom...
Sorption of molecular amines by montmorillonite involves protonation of the amine group and hydrolysis of the interlayer cation. Sorption and subsequent desorption of amines may render some of the interlayer cations non-exchangeable, thus causing partial 'chloritization' of the montmorillonite. The effect is stronger with interlayer A1 than Ca ions and depends upon the amine sorbed. I N T R O D...
We previously reported that 3-hydroxy fatty acids promoted the survival of cryptococcal cells when acted upon by amoebae. To expand on this, the current study sought to explain how these molecules may protect cells. Our data suggest that 3-hydroxy fatty acids may subvert the internalization of cryptococcal cells via suppression of the levels of a fetuin A-like amoebal protein, which may be impo...
The aim of the study was to investigate effects of the triazine's herbicide terbuthylazine-2-hydroxy on early life stage of common carp (Cyprinus carpio L.) through antioxidant indices, mortality, growth, development, and histopathology. Based on accumulated mortality in the experimental groups, lethal concentrations of terbuthylazine-2-hydroxy were estimated at 35-day LC50 = 10.9 mg/L terbuthy...
Beta-hydroxy fatty acids are a major component of lipid A moiety of lipopolysaccharide. We aimed to investigate the role of free beta-hydroxy fatty acids on inflammation, as well as to evaluate their effects on cytokine release from human blood cells, and whether they exist in plasma of patients with chronic inflammatory diseases with/without insulin resistance. Peripheral venous blood was incu...
Hydroxy-L-proline was first isolated by Fischer in 1902 from a hydrolysate of gelatin (l).l The synthesis and determination of the structure were reported by Leuchs and coworkers (5--g), and, in 1919, the separation of the two racemic stereoisomers and the resolution of each racemate through mixtures of quinine with the corresponding N-phenylisocyanate derivatives were accomplished (5). In the ...
Liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was used for simultaneous quantification of tolterodine and its metabolite 5-hydroxy methyl tolterodine in rat plasma. Tolterodine-d6 and 5-hydroxy methyl tolterodine-d14 were used as internal standards (IS). Chromatographic separation was performed on Ascentis Express RP amide (50 mm×4.6 mm, 2.7 μm) column with an isocratic mobil...
A total of 215 Streptomyces strains were screened for their capacity to regio- and stereoselectively hydroxylate beta- and/or alpha-ionone to the respective 3-hydroxy derivatives. With beta-ionone as the substrate, 15 strains showed little conversion to 4-hydroxy- and none showed conversion to the 3-hydroxy product as desired. Among these 15 Streptomyces strains, S. fradiae Tü 27, S. arenae Tü ...
Expecting that the different characteristics of rice plants against rice blast fungus, that is, susceptibility of the weaker cultivar, Sasanishiki and resistance of the stronger cultivars, Fukuyuki and Fukunishiki, may be due to the absence or presence of anti-fungus compounds in the rice plants, the anti-rice blast fungus substances in these three kinds of rice plants were explored. We found f...
