This study established a novel non-invasive and efficient analysis method which can be applied in research of individual’s psychological stress. Because in the different state of psychological stress, the oral secretion of salivary α-amylase will be changed under the control of the hypothalamuspituitary-adrenal medulla secretion system. Many studies have confirmed that salivary α-amylase measur...

the carob moth is one of the most devastating pests of pomegranate and some other products. various pest control measures have been undertaken in order to control this pest but none of them has been successful so far. in the current study the effects of cereal seed proteinaceous extracts including triticale and three wheat cultivars (mv17, aflak, and zare) have been studied on α-amylase and pro...

This study aims to co-microencapsulate the Ruellia tuberosa L. and Cosmos caudatus K. extracts, with chitosan–sodium tripolyphosphate (Na-TPP) as coating material. α-Amylase inhibition antioxidant assays were conducted determine potential of microcapsules used antidiabetic agents. The manufactured under influences pH, Na-TPP concentration, stirring time. optimum microencapsulation conditions se...

Introduction: α-amylase is a major form of amylase found in humans and other mammals. It is the special key enzyme involved in carbohydrates breakdown. Inhibition of this enzyme could be used in treatment of diabetes. In this study, the effect of ten Iranian macrolichens on alpha amylase were tested. Methods: Different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated wi...

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...

This study aimed to investigate the effect of an innovative ecofriendly process—instant controlled pressure drop technology, also known as “détente instantanée contrôlée” or DIC—coupled with Tripolium extraction (DIC-Tripolium), on hesperidin recovery, and antioxidant antidiabetic activities orange byproduct extracts. A DIC pretreatment was applied partially dried byproducts (~16% wet basis). c...

A new thermostable α-amylase from Rhizopus oryzae FSIS4 was purified for first time and recovered in a single step using a three-phase partitioning (TPP) system. The fungal α-amylase, at a concentration of 1.936 U per kg of flour, was used in bread-making and compared to the commercial enzyme. The results showed a significant effect of the recovered α-amylase in the prepared bread and allowed u...

α-Amylase-binding streptococci (ABS) are a heterogeneous group of commensal oral bacterial species that comprise a significant proportion of dental plaque microfloras. Salivary α-amylase, one of the most abundant proteins in human saliva, binds to the surface of these bacteria via specific surface-exposed α-amylase-binding proteins. The functional significance of α-amylase-binding proteins in o...

BACKGROUND Obesity and overweight are consistently associated with metabolic disorders including hyperglycemia and hyperlipidemia. Herbal medicines have been currently suggested as an alternative source of potentially useful antihyperglycemic, antihyperlipidemic, antioxidant activities. The objective of this study was to assess the in vitro inhibitory effects of eleven herbal medicines on carbo...
