BACKGROUND Urate urolithiasis is a common problem in breed homozygous for the mutation that results in hyperuricosuria. Low purine diets have been recommended to reduce purine intake in these dogs. METHODS A higher protein, purine restricted diet with water added was evaluated in dogs with genetic hyperuricosuria and a history of clinical urate urolithiasis over a one year time period. Dogs w...

Abstract Cultivar Barangan is one of the famous banana plants that has good taste and price. The disadvantages this susceptible to Fusarium disease. Tissue culture techniques ways propagation for plant. This study aimed determine effective concentration benzyl amino purines (BAP) indole-3 acetic acid (IAA) optimal multiple bud clumps (MBC) induction in explants Merah banana. Research was carrie...

The synthesis of new derivatives 2-[(1,4-dioxo-1-amino-4-arylbutyl-2-en-2-yl)amino]-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylic acid is described. Starting 2-{[5-aryl-2-oxofuran-3(2H)-ylidene]amino}thiophene-3-carboxylic acids were obtained by intramolecular cyclisation substituted 4-aryl-4-oxo-2-thienylaminobut-2-enoic in acetic anhydride. New via decyclization reaction acids. structure t...

For this report, we analyzed protein secondary structures in relation to the statistics of three nucleotide codon positions. The purpose of this investigation was to find which properties of the ribosome, tRNA or protein level, could explain the purine bias (Rrr) as it is observed in coding DNA. We found that the Rrr pattern is the consequence of a regularity (the codon structure) resulting fro...

If amino-acids are treated in glacial acetic acid solution with the theoretical amount of acetic anhydride, optically active acetamino-acids are obtained, while if a large excess of acetic anhydride is used, racemization and/or formation of azlactones takes place [Bergmann et al. 1926; Bergmann & Zervas, 1928]. Excess of acetic anhydride causes racemization even in aqueous solution in the prese...

chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. we looked for the presence of this compound in the callus cultures of varthemia persica dc (var. persica ). we have evaluated the conditions for establishment of callus cultures of v. persica and the in vitro production of chlorogenic acid. callus was initiated ...

Nucleotides are low molecular weight intracellular compounds that play major roles in physiological and biological functions. They act as precursors for nucleic acid synthesis and are also fundamental for intermediary metabolism. Nucleotides and nucleic acids turn over rapidly, especially in growing tissues or those undergoing constant cell renewal. Tissues that grow have a net formation of new...

2-[2-(2,6-Dichlorophenyl)amino]phenylmethyl-3-{4-[(substituted phenyl)amino]-1,3-oxazol-2-yl)-7-chloroquinazolin-4(3H)ones 5a-o have been prepared from 2-[(2,6-dichloro phenyl)amino]phenyl acetic acid 1, which was converted to acid chloride 2 and cyclized with anthranilic acid afforded benzoxazin-4(H)ones 3. Further reaction with urea gave carboxamide-7-chloroquinazolin-4(3H)ones 4 cyclized wit...
