introduction: recently depleted uranium is being widely used as anti-armour ammunition and at very high temperature, results in information of an aerosol of very small uranium oxide particles, which may be inhaled. it is alleged that these particles represent a new battlefield hazard because of the chemical toxicology and/or radioactivity. method & materials: male wistar strain albino rats were...

background and objectives: in the era of global industrialization, enzymes are being used extensively in the various sectors including food processing. owing to the high price of enzymes, various initiatives have been undertaken by the r&d; sector for the development of new processes or improvement in the existing processes for production of cost effective enzymes. with the advancement in the f...

background: halothane is the routine used inhalation anesthetic drug in the world but at present, there is an increasing interest for using intravenous anesthetics like propofol. the purpose of this study was to compare these anesthetic effects on hepatic enzymes.methods: from 2006 to 2007, this study was performed on fifty eight patients classified in class i of american society of anesthetics...

background: the early stage of copper poisoning is difficult to be clinically diagnosed in sheep and has not been documented clearly yet. objectives: to assess biomarkers in predicting early copper poisoning in sheep, blood samples were collected from several groups of animals from a naturally copper poisoning occurrence in an industrial region. methods: animals were divided into four experimen...

canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...

screening of3000 soil samples collected from cities of four different provinces of iran for starch-hydrolysing bacteria revealed that the nature is enriched with streptomyces species capable of producing amylolytic enzymes. among the bacterial isolates, one of the high starch-degrading strains was selected for further microbiological identification and also amylolytic enzyme(s) characterization...

A high-throughput screening protocol for evaluating chimeric, self-sufficient P450 biocatalysts and their mutants against a panel of substrates was developed, leading to the identification of a number of novel biooxidation activities.

Lignocellulose is the most abundant carbohydrate source in nature and represents an ideal renewable energy source. Thermostable enzymes that hydrolyze lignocellulose to its component sugars have significant advantages for improving the conversion rate of biomass over their mesophilic counterparts. We review here the recent literature on the development and use of thermostable enzymes for the de...

Metagenomics has accelerated the process of discovery of novel biocatalysts by enabling scientists to tap directly into the entire diversity of enzymes held within natural microbial populations. Their characterization has revealed a great deal of valuable information about enzymatic activity in terms of factors which influence their stability and activity under a wide range of conditions. Many ...
