BACKGROUND [corrected] Recent studies indicate that hyperthermia can change inflammatory mechanisms and protect experimental animals from deleterious effects of secretagogue-induced acute pancreatitis AIM To evaluate the effects of hyperthermia post-treatment on cerulein-induced acute pancreatitis in rats METHODS Twenty animals were divided in two groups: group I (n = 10), rats with cerulei...

The aim of this study is to optimize the production of Baker’s yeast, Citric acid, Ethanol and α-amylase using dates of low market value as the basal fermentation medium. The results of this study showed that the optimal Baker’s yeast production was obtained with a dilution rate of 0.22 h-1. Also, the use of ammonium phosphate provides better biomass yields compared to urea. As for the Ethanol ...

Résumé Le Moullac G., A. Van Wormhoudt, AQUACOP. Aquat. Living Resour., 1994, 7 , 203-210. Activity of digestive enzymes (trypsin, chymotrypsin and amylase) was studied in relation with food in Penaeus vannamei larvae first stages. Microparticles containing casein involved the decrease of soluble protein content and enzyme activities. Specific trypsin activity but not chymotrypsin was correlate...

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...

N.sitophila was grown under controlled conditions of solid state and submerged fermentation on Sago hampas. The optimum conditions of protein enrichment previously established for sugar beet pulp was used for this study. Under this condition the protein content of Sago hampas under solid state increased from 1.4 to 14.45% (W/W) whereas for Sago hampas and Sago starch, the protein content under ...

The mean amylase level in 42 human bile samples was 154 IU/l and there was no significant difference in the amylase activity of 32 paired serum and bile samples. Estimation of the amylase thermolability of bile showed it to be similar to that of serum. This suggests that the amylase activity in bile may have filtered through the liver from the hepatic circulation rather than refluxed from the p...

The relative levels of pancreatic amylase mRNA closely parallel the 3-fold variation of pancreatic amylase protein levels observed in several mouse strains studied. In contrast pancreatic elastase mRNA levels were similar in these strains. Each of the strains contained the same number of amylase-like genes (about 8). The selective variation in the pancreatic amylase gene expression could be due...

The gene for beta-amylase was isolated from BacUlus polymyxa by molecular cloning in B. subtils. B. subtlis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydrolysis with this beta-amylase produces maltose, not glucose, whereas maltotriose ...

In 1988, Hata et al. [1] reported a case of ectopic production of salivary-type amylase by an IgA-type multiple myeloma. Subsequently, seven cases of amylaseproducing multiple myeloma have been reported [2-8]. According to Delannoy et al. [7], amylase-producing myeloma should be added to the list of amylaseproducing tumors. In 1991, we reported a neuraminidase sensitive, so-called sialyl, saliv...

We describe a family of 32 subjects, including two healthy siblings without detectable pancreatic amylase in serum and five healthy relatives (one of them a sister) exhibiting subnormal pancreatic amylase activities. Comparisons of immunoreactive amylase concentrations with the corresponding amylase activities may justify the assumption of a "silent" Amy-2 allelic variant.
