background: the mechanism of hypoglycemic and hypolipidemic activities of pyrus biossieriana buhse leaf extract (pbble) and its phytochemical component arbutin, have not been well determined. the present study was performed to understand the hypoglycemic activity mechanisms of pbble and arbutin more clearly.methods: in vitro enzymatic carbohydrate digestion with pbble and arbutin was assessed u...

this study investigated the effects of coenzyme q10 (coq10) supplementation on hematological, enzymes activities and biochemical parameters in broilers with pulmonary hypertension syndrome (phs).two hundred and forty 1-d-old ross 308 male broiler chicks were randomly allocated into 3 groups with 4 replicates. from d 14, the diets were supplemented with coq10 at levels of 0, 20 and 40 mg/kg, res...

background: a cross sectional study was conducted to determine the association between occupational stress risk factors and salivary alpha-amylase activity levels among fresh fruit bunch (ffb) cutters at oil palm plantation.  methods: a total of 109 ffb cutters were selected from two oil palm plantations in pulau carey, selangor at west coast of malaysia in 2015. questionnaires were used to det...

in this paper, covalent immobilization of beta amylase enzyme on the surface of modified magnetic nano particles (znfe2o4@sio2-nh2) is reported. for doing so, at first, the magnetic nanoparticles of znfe2o4 were synthesized by chemical co-precipitation method and then tetraethyl orthosilicate (teos) and 3-aminopropyltriethoxy silane (aptes) were used for modification of znfe2o4 nanoparticles wi...

Two proteins (A-1 and B-2) with -amylase inhibitor activity were extracted and partially purified from Colocasia esculenta tubers through 80% ammonium sulphate fractionation, ion-exchange chromatography on DEAE -Sephacel and gel-chromatography on Sephadex G-100. The molecular weight of A-1 and B-2 were estimated to be about 17000 and 19000 daltons, respectively. The inhibitors inactivated -am...

It was proposed to find out the optimum environmental conditions and nutritional requirements for highest growth -regulating substance and enzyme production by Streptomyces olivaceoviridis. The optimum a-amylase and proteinase activity was at 45'C and 50'C, respectively. The test strain appeared to prefer pH 4.8 and 7.0 for the maximum productivity of a-amylase and proteinase, respectively. The...

AIMS To explore relations between exposure to fungal alpha-amylase and the risk of new work related respiratory symptoms or sensitisation. METHODS A prospective cohort study among 300 bakers and millers was followed up for a maximum of seven years. Exposure to alpha-amylase was estimated by air measurements and questionnaires and classified into three categories. Symptoms were recorded with a...

Background: Diagnosis of acute pancreatitis is based on raised serum lipase and amylase in the blood. However, levels urinary can be sought for being less invasive. The study aimed to find out diagnostic accuracy compared their association with degree severity pancreatitis. Methods: A randomized clinical control was conducted n=180 patients (18-50 year) Ziauddin PNS Shifa Hospital, Karachi from...

Previous studies related to digestive enzyme activity have been carried out, but there is no information the effect of temperature on trypsin-like and amylase in Rsbora lateristriata. Therefore, purpose this study was determine differences digestion Rasbora lateristriata fish. The treatments applied were 20, 30, 40, 50, 60, 70ºC each treatment repeated five times. A total 125 fish with a body w...
