background: in algeria the date wastes production is estimated at least 85.000 tones. date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced.objective: the aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. materials...

?-amylase inhibitory activities of ethanol extracts from six selected iranian salvia species (s. hydrangea dc., s. hypoleuca benth., s. officinalis l., s. reuterana boiss., s. verticillata l. and s. virgata jacq.) were examined, using in vitro model. in addition, antioxidant capacities (dpph• radical scavenging) and total flavonoid cotents of the extracts were also determined. the results showe...

Amount of chlorophyll content, Proteins, Carbohydrates and RNA has been studied in ten taxa of Mosses. The study also embodies the specific activity of enzymes α-amylase, ß-amylase, Proteases and polyphenol oxidases. It has been found that carbohydrate content is more than protein content in Atrichum pallidum, Thuidium recognitum, Brachythecium kamounense and Funaria hygrometrica, whereas, tota...

To determine the mechanism(s) responsible for glucocorticoid-induced increases in amylase content in pancreatic acinar AR42J cells, we examined the effects of dexamethasone on amylase protein biosynthesis, steady-state mRNA levels, and gene transcription. Dexamethasone treatment led to a dose-dependent increase in amylase synthesis which was one-half maximal at 2 nM and maximal at 100 nM where ...

Stimulation of the beta-adrenergic or cholinergic muscarinic receptors are the principal mechanisms by which parotid salivary secretion is regulated in vivo. In this study we have examined the effects of cholinergic stimulation on amylase gene expression in dispersed rat parotid cells. [3H]Leucine incorporation into amylase and total protein was inhibited by carbamylcholine. Within 5 min of its...

the objective of the present study was to determine the antilipidperoxidation and in vitro α-amylase and lipase inhibitory activity of the boswellia ovalifoliolata bal henry (bob) extract. the polyphenolic compounds, flavonoids, and tannins content of the extracts were estimated by spectrophotometry. antioxidant activity on goat liver lipid peroxidation and linoleic acid was determined.moreover...

besides the high starch content, sweet potato contains endogenous amylases where the two predominants are - and β-amylases. sweet potato is thought to be a promising source of β -amylase since β -amylase is one of the major protein in the tubers. this investigation has focused on the properties of β amylase from white-flesh sweet potato that has been grown in iran as a potential source for indu...

Postprandial hyperglycemia is a prime characteristic of diabetes mellitus and has been a focus in the therapy for diabetes. One of the therapeutic approaches which involve decreasing hyperglycemia aims at inhibiting the enzyme α-amylase. The leaves of T. populnea were studied for the presence of amylase inhibitors. The fractions obtained by successive fractionation using solvents of varying pol...

The effects of Saiko-ka-ryukotsu-borei-to (SRBT), a Chinese medicinal prescription, on mouse serum amylase activity were investigated in vivo. SRBT was found to not only dose- and/or time-dependently augment amylase activity, but also to increase alpha-amylase protein content and soluble starch metabolic activity. These results provide a rational basis for the clinical use of SRBT that may acco...
