The aim of this study was to establish and quantify changes in the activities of total, free and bound fractions of pancreatic lipase, galactoso-6-sulphatase, beta-D-galactosidase and N-acetyl-beta-D-glucosaminidase in the course of alloxan-induced diabetes mellitus. Rabbits were divided into a control group and groups injected with alloxan on the 21st, 42nd, 90th and the 180th day, after which...

Candida dubliniensis is an opportunistic yeast that has been recovered from several body sites in many populations; it is most often recovered from the oral cavities of human immunodeficiency virus-infected patients. Although extensive studies on epidemiology and phylogeny of C. dubliniensis have been performed, little is known about virulence factors such as exoenzymatic and hemolytic activiti...

Human N-acetylgalactosamine 6-sulphatase (EC 3.1.6.14), which is involved in the lysosomal degradation of the glycosaminoglycans keratan sulphate and chondroitin 6-sulphate, was purified more than 130000-fold in 2.8 % yield from liver by an eight-step column procedure. One major form was identified with a pl of 5.7 and a native molecular mass of 62 kDa by gel filtration. When analysed by SDS/PA...

Iduronate sulphatase (IDS) is responsible for mucopolysaccharidosis type II, a rare recessive X-linked lysosomal storage disease. The aim of this work was to evaluate the functional importance of each N-glycosylation site, and of the cysteine-84 residue. IDS mutant cDNAs, lacking one of the eight potential N-glycosylation sites, were expressed in COS cells. Although each of the potential sites ...

( 1) A method is described for assaying brain for cerebroside galactosidase activity. The enzyme was liberated by sonication and addition of sodium taurocholate, then by digestion with pancreatic enzymes. It was further purified by precipitation at pH 3. The enzyme was then incubated with an emulsion of galactose-labelled cerebroside in taurocholate and oleate at pH 4.5, and the liberated galac...

background: endometrial remodeling occurs during each menstrual cycle in women. reports have shown that, in a variety of cell types, processes such as proliferation, signaling complex formation and extra cellular matrix remodeling require a cytoplasmic tyrosine kinase, focal adhesion kinase (fak). the present study has focused on the expression pattern of fak in human endometrium during the men...

the effects of steroid hormones, glucagon and insulin on rat liver phosphatidate phosphohydrolase (pap) activity were studied both in vitro and in vivo. incubation of rat hepatocytes with each hormone showed that dehydroepiandrosterone (dhea), progesterone and testosterone increase pap activity by 44.6, 37 and 36.9%, respectively. estradiol, however, decreased enzyme activity by 13.6% under the...

asthma is one of the most common chronic diseases of childhood. inhaled corticosteroids (ics) are the recommended controller drug for asthma treatment. the aim of our study was to determine concerns and fears of parents of children with asthma towards the use of ics. one hundred parents of asthmatic children were interviewed using structural questionnaire. airway inflammation was reported by on...
