even purified enzyme preparations are often heterogeneous. for example, preparations of aspartate aminotransferase or cytochrome oxidase can consist of several different forms of the enzyme.  for this reason we consider how different the kinetics of the reactions catalysed by a mixture of forms of an enzyme must be to provide some indication of the characteristics of the species present.  based...

hydatid disease is caused by the larva of echinococcus granulosus parasite. mebendazole (mbz) is used as an alternative choice for the treatment of the disease. aspartate aminotransferase (ast) is an essential enzyme in amino acid metabolism. the aim of the present study is to evaluate the effect of mbz on ast activity of hydatid cyst parasite in order to detect enzymatic parameter for drug eff...

background: pentoxifylline might have a role in the suppression of inflammatory cytokines in non-alcoholic fatty liver disease (nafld).the aim of study  was  to evaluate the effect of pentoxifylline on liver function tests in non-diabetic subjects with nafld. materials and method: this clinical trial was performed in 120 nafld patients. they were divided to two groups by balance block randomiza...

Magnesium aspartate, potassium aspartate, magnesium potassium aspartate, calcium aspartate, zinc aspartate, and copper aspartate as.Two aspartate aminotransferase EC 2. transfer of an amino group from aspartate to 2-oxoglutarate in order to form.Aspartate Aminotransferase AST in Refrigerated Serum NHANES 2001-2002. The AST catalyzes the reversible transamination of L-aspartate and. Abstract: Th...

Inactivation of tyrosine aminotransferase induced in vivo by triamcinolone was studied in a homogenate incubated at neutral pH values. The integrity and the presence of subcellular particles together with a compartment of acidic pH are necessary for inactivation of tyrosine aminotransferase. It is suggested that tyrosine aminotransferase is inactivated inside lysosomes. The system responsible f...

Total mitochondrial aspartate aminotransferase (EC 2.6.1.1), the sum of apo- and holo-mitochondrial aspartate aminotransferase activity in human serum, was measured by using a proteolytic method: inactivation of cytosolic aspartate aminotransferase with cytosolic aspartate aminotransferase-inactivating protease 401 from Streptomyces violaceochromogenes. Cytosolic aspartate aminotransferase is c...

OBJECTIVES Elevated alanine aminotransferase can heighten concern for the presence of nonalcoholic fatty liver disease in obese children. Guidelines recommend alanine aminotransferase screening of obese children start at the age of 10 years. We examined alanine aminotransferase values routinely obtained for tertiary obesity care among preschool (2-5 years) and school-age children. METHODS Med...
