the alteration of cytokine balance is stated to exert greater influence on gingival overgrowth compared to the direct effect of the drug on the regulation of extracellular matrix metabolism. the current study evaluated the effect of phenytoin on the regulation of collagen, lysyl oxidase and elastin in gingival fibroblasts.normal human gingival fibroblasts (hgfs) were obtained from 4 healthy chi...
b a ckground: anoph eles fluviatilis , one of the major malaria vectors in iran, is assumed to be a complex of sibling species. the aim of this study was to evaluate cytochrome oxidase i (coi) gene alongside 28s-d3 as a diagnostic tool for identification of an. fluviatilis sibling species in iran. m e t hods: dna sample belonging to 24 an. fluviatilis mosquitoes from different geographical area...
Some strains of Aeromonas hydrophila may be oxidase negative or only weakly oxidase positive by the Kovacs method taken from the surface of a differential medium, such as MacConkey agar. Six strains of A. hydrophila, two oxidase variable, one oxidase constant, and three weakly oxidase positive on MacConkey agar, were studied to determine the cause of oxidase variability. The bacteriostatic dyes...
polyphenol oxidase (ec. 1.10.3.1 ppo), an ionically unbound and thermostable enzyme, was extracted from the leaves of cinnamomum tamala having aroma flavor used to add in indian food and vegetables as a part of spices to enhance the taste of recipes. the enzyme was purified 2.63-fold with a total yield of 9.5% by ammonium sulfate precipitation followed by sephadex g-100 gel filtration chromatog...
Objective: Polyphenol oxidase or PPO (EC 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. The objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of Cysteine, Ascorbic acid, citric acid, kojic acid and glycine at two different pH (6 and 7) in hawthorn. Me...

To study the effects of water stress on compatibility metabolites and the antioxidant enzyme activities of wheat variety trial a factorial experiment was conducted in a completely randomized design in 1393. The experiment consisted of three levels of stress (85, 60 and 35% of field capacity) and five varieties of wheat (Orom, Zarea, Mihan, ZSZOBKAYKA, JS3l7G217,) Analysis of variance showed, Pr...

Attempts to obtain experimental values for the kinetic parameters of phenanthridine oxidation by guinea pig or rabbit liver aldehyde oxidase using common spectrophotometric methods have not been successful due to a lower limit of detection. In the present study, a new spectrofluorimetric assay in combination with a multivariate calibration method for enzymatic kinetic study of aldehyde oxidase ...
