To examine further a previously reported association between amylase gene polymorphism and growth in the Pacific oyster Crassostrea gigas, ecophysiological parameters and biochemical and molecular expression levels of alpha-amylase were studied in Pacific oysters of different amylase genotypes. Genotypes that previously displayed significantly different growth were found to be significantly dif...

Background. Serum lipase and amylase are biochemical analyses used to establish the diagnosis of acute pancreatitis (AP). Despite lipase having been shown internationally to be a more sensitive and specific test, amylase remains a popular first-line test.Objective. To provide a local basis for the recommendation of the best first-line laboratory test, an assessment of their performance in our l...

Human salivary amylase and pancreatic amylase were purified and characterized. These amylases gave two bands and one band, respectively, each staining for both protein and sugar, after electrophoresis on sodium dodecyl sulfate--polyacrylamide gel. The relative molecular mass (Mr) or pancreatic amylase was calculated to be 60 000; for the two components (A and B) of salivary amylase the Mr were ...

BACKGROUND Starch-degrading amylase enzyme is important in biotechnological applications as food, fermentation, textile, paper and pharmaceutical purposes. The aim of current study to isolate alkaline thermostable α-amylase bacteria and then study the composition of medium and culture conditions to optimize cells growth and a-amylase production. MATERIALS AND METHODS Thermophilic amylase prod...

Drosophila melanogaster larvae excrete amylase and perform external digestion of their food. In this study, to investigate whether their external digestion ability varies in response to changes in the external environment, we measured the relative amount of amylase excreted by larvae using a new method: the iodine starch agar method (ISAM). Analysis using this method revealed that the amount of...

introduction and aims: noscapine has been recently known as an antagonist of bradykinin, and in this study its effect on the animal model of acute pancreatitis has been evaluated. materials and methods: 49 male wistar rats have been evaluated in five experimental and four control groups. common bile duct has been ligated by means of surgery to induce acute pancreatitis in rats. the resulted inf...

In commercial transactions, an intermediary might be involved to help transacting parties to conduct their business. Nevertheless, the intermediary may not be fully trusted. In this paper, we introduce the concept of intermediary (or agent) in a non-repudiation protocol, define the aims of intermediary non-repudiation protocols, and analyze their security requirements. We present a simple scena...

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 sil...

We investigate the role of commissions paid by product providers to information intermediaries who advise customers on product suitability. These commissions and hidden “kickbacks” are widespread and controversial in markets for retail financial products and health services. We show that product providers have an incentive to pay commissions to steer the intermediary’s advice and to counteract ...
