Of alpha-amylases and other starch-digesting enzymes from bacteria and plants.ess was supplemented with bacterial and fungal amylases or scalded flour. Immunochemical characteristics of alpha-amylase sensitization.Alpha-amylase production and its activity was compared in two different. Bacterial amylases are resistant to high temperatures, they can active in wide pH.fungal amylascs lowest, liqu...

The clearance of pancreatic and salivary amylase relative to creatinine was measured in 26 control subjects and 22 patients with chronic pancreatitis. Control values for pancreatic amylase clearance (+/- SD) were 2.64 +/- 0.86% compared with 1.54 +/- 0.95% for salivary amylase. In chronic pancreatitis, pancreatic amylase clearance ratios were significantly higher than controls (P less than 0.00...

A normal paediatric range of plasma alpha-amylase activity was determined using the Phadebas blue starch method. The range for children over one year was 98--405 IU/l. Plasma amylase activity increased throughout infancy. Mature levels of activity were observed in some children by age 2 months and in most of them by 9 months.

Biochemical analysis and immunohistochemical techniques support the theory that hyperamylasaemia in lung cancer is due to amylase production in carcinoma cells. The vast majority of amylase-producing carcinomas are adenocarcinomas with amylase isoenzyme similar to the salivary type. This prospective study assesses alpha-amylase expression in resectable lung cancer. Seventy four patients with re...

Genetic studies have demonstrated that salivary and pancreatic amylase genes are closely linked in human and mouse. To analyze the arrangement of genes within the amylase cluster, a library of YBR mouse genomic DNA was cloned in the cosmid vector pJB8. Clones containing amylase genes were identified by hybridization with amylase cDNA probes. Salivary and pancreatic amylase genes were isolated o...

  Background Recent studies indicate increased serum amylase in children with acute appendicitis. The objective of the current study was to determine the diagnostic accuracy of raised serum amylase level in prediction of perforated appendicitis in children with acute appendicitis. Materials and Methods In this cross-sectional study, 61 children (aged 3 to 15 years) who underwent appendectomy su...

Protein activation of urinary alpha-amylase (EC 3.2.1.1) activity was observed during an evaluation of the Du Pont aca procedure for the determination of urinary alpha-amylase. This activation effect became constant for urinary albumin concentrations exceeding 1.50 g/liter. It is recommended that urinary alpha-amylase be analyzed with sufficient albumin added to maximize this effect. The aca al...

Objective(s):One strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. Plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. Materials and Methods: Urtica dioica and Juglans regia Linn were tested for α-amylase inhibition. Different concentrations of leaf aqueous extracts were incubated with enzym...

The growth and bioconversion potential of selected strains growing on cassava waste substrate during solid state fermentation were assessed. Rhizopus stolonifer showed the highest and the fastest utilization of starch and cellulose in the cassava waste substrate. It showed 70% starch utilization and 81% cellulose utilization within eight days. The release of reducing sugars indicating the subst...

The aim of this study was screening fungi strains, isolated from manipueira (a liquid subproduct obtained from the flour production of Manihot esculenta), for amylases production and investigating production of these enzymes by the strain Aspergillus 6V4. The fungi isolated from manipueira belonged to Ascomycota phylum. The strain Aspergillus 6V4 was the best amylase producer in the screening a...
