Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common disease of the hexose monophosphate pathway existing in more than 400 million people worldwide. The aim of this study was to identify neonates with G6PD deficiency following national program for screening and education of affected newborns’ parents started since June 2007 in Mazandaran, a northern Province of Ira...

in this paper a first step in classifying the fuzzy normalsubgroups of a finite group is made. explicit formulas for thenumber of distinct fuzzy normal subgroups are obtained in theparticular cases of symmetric groups and dihedral groups.

It was deduced many years ago from indirect evidence that demolybdo xanthine oxidase is present in normal bovine milk. This has now been confirmed by isolation of this enzyme form by a method based on the folate-gel affinity-chromatography procedure described Nishino & Tsushima [(1986) J. Biol. Chem. 261, 11242-11246]. Enzymic and spectroscopic properties of demolybdo xanthine oxidase, which re...

Polynucleotide kinase from E. coli infected with the PseT 1 mutant of bacteriophage T4 has been isolated. The PseT 1 enzyme purifies similarly to normal polynucleotide kinase and effectively transfers the gamma phosphate of ATP to the 5' terminal hydroxyl of DNA and RNA. The PseT 1 and normal enzymes require similar magnesium ion concentrations, have the same pH optima and are both inhibited by...

mucopolysaccharidoses are a group of rare mostly autosomal recessive metabolic and genetic disorders. because of the high rate of consanguinity, they are not uncommon in our population. clinical diagnosis is not difficult for experienced physicians, but it is not enough for treatment and prevention measures in the future pregnancies. so, it is necessary to detect the type of mps by measurement ...
