Background & Aim: Singhnad Guggulu is a traditional Ayurvedic formula for detoxifying and rejuvenating the joints. The present study was to investigate the α-amylase inhibition and antioxidant activities of aqueous extract of Singhnad Guggul (AESG). Experimental: α-Amylase inhibition assay by dinitro-salicylic acid method and antioxidant activity by ferric chelating and ferrous reducing assay....

It is believed that the inhibition of carbohydrate hydrolyzing enzymes including α-amylase and α-glucosidase is one of the therapeutic approaches to decrease the postprandial glucose level after a meal, especially in the people with type 2 diabetes. Medicinal plants and their extracts are one of the main sources to find new inhibitors to the enzymes. In our study four flavonoids, namely luteoli...

The inhibitory effects of Avena sativa L. seed extract were studied on life history and some physiological aspects of Sitotroga cerealella (Olivier; Lepidoptera: Gelechiidae). The inhibition of α-amylase activity in vitro by A. sativa proteinaceous extract suggested its potential antimetabolic effect on S. cerealella larvae. Although, chronic ingestion of A. sativa inhibitor (I10: 0.108 mg prot...

BACKGROUND AND AIMS α-Amylase in grass caryopses (seeds) is usually expressed upon commencement of germination and is rarely seen in dry, mature seeds. A heat-stable α-amylase activity was unexpectedly selected for expression in dry annual ryegrass (Lolium rigidum) seeds during targeted selection for low primary dormancy. The aim of this study was to characterize this constitutive activity bioc...

Alpha-amylases are ubiquitously distributed throughout microbials, plants and animals. It is widely accepted that omnivorous crustaceans have higher α-amylase activity and number of isoforms than carnivorous, but contradictory results have been obtained in some species, and carnivorous crustaceans have been less studied. In addition, the physiological meaning of α-amylase polymorphism in crusta...

The secretion of salivary α-amylase is influenced by adrenergic regulation of the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis; thus, exercise affects the levels of salivary α-amylase. Granger et al published a review in 2007 that focused attention on salivary α-amylase. In addition, a portable system for monitoring salivary α-amylase activity was launched in Japan at ...

Amylase plays an important role in biotechnology industries, and Gram-positive bacterium Bacillus subtilis is a major host to produce heterogeneous α-amylases. However, the secretion stress limits the high yield of α-amylase in B. subtilis although huge efforts have been made to address this secretion bottleneck. In this question-oriented review, every effort is made to answer the following que...

Thermostable α-amylase is of great importance in the starch fermentation industry; it is extensively used in the manufacture of beverages, baby foods, medicines, and pharmaceuticals. Bacillus amyloliquefaciens produces thermostable α-amylase; however, production of thermostable α-amylase is limited. Ion-beam implantation is an effective method for mutation breeding in microbes. We conduct...

BACKGROUND Breast cancer is one of the most diagnosed cancers in females, frequently with fatal outcome, so that new strategies for modulating cell proliferation in the mammary tissue are urgently needed. There is some, as yet inconclusive evidence that α-amylase may constitute a novel candidate for affecting cellular growth. METHODS The present investigation aimed to examine if salivary α-am...

Microbial fermentation could produce many active substances in green and pollution-free ways. In recent years, studies on the hypoglycemic ability of microorganisms had become a trending topic prevention treatment diabetes. Garlic is food containing variety biologically physiological functions, but it not accepted by general public because its strong pungent smell. our study, with potential eff...
