The current study deals with a digestive α-amylase in the larvae of Pieris brassicae L. through purification, enzymatic characterization, gene expression, and in vivo effect of a specific inhibitor, Acarbose. Although α-amylase activity was the highest in the whole gut homogenate of larvae but compartmentalization of amylolytic activity showed an equal activity in posterior midgut (PM) and ante...

This study aimed to evaluate in vitro free radical scavenging activity and anti-diabetic properties of extracts from the sprout Borassus fabellifier. Antioxidant was performed using DPPH, ABTS, FRAP, SO, NO inhibition methods. The enzymes (α-amylase α- Glucosidase inhibitory activities were investigated. Moreover, glucose adsorption diffusion also studied confirm potential effect B. fabellifier...

Introduction: Identification of serous acinar differentiation is the basic step for the diagnosis of acinic cell carcinoma (ACC). α-amylase was described to be specific for normal acinar cell but its affinity to malignant counterpart is being contentious. Recently discovered marker anoctamin (DOG1) specific for diagnosis of GISTs has been reported for its efficacy to stain the malignant acinar ...

Inhibition of α-amylase, enzyme that plays a role in digestion of starch and glycogen, is considered a strategy for the treatment of disorders in carbohydrate uptake, such as diabetes and obesity, as well as, dental caries and periodontal diseases. Plants are an important source of chemical constituents with potential for inhibition of α-amylase and can be used as therapeutic or functional food...

BACKGROUND Sensitization to flour or fungal alpha-amylase is a prerequisite for the development of respiratory allergy in bakers. The knowledge of occupational allergen sensitization among bakery workers will facilitate the implementation of preventive measures for respiratory allergies in bakeries. The objective of this study was to determine the prevalence and factors associated with sensitiz...

α-Amylase is one of the important enzymes in the starch-processing industry. However, starch processing requires high temperature, thus resulting in high cost. The high adsorptivity of α-amylase to the substrate allows this enzyme to digest the starch at a lower temperature. α-Amylase from Saccharomycopsis fibuligera R64 (Sfamy R64), a locally sourced enzyme from Indonesia, has a high amylolyti...

α-amylase inhibitors are used in the treatment of type II diabetes mellitus. This study aims to identify the α-amylase inhibitors from two medicinal plants Mentha piperita and Annona squamosa. Primarily, the extract of both leaves was prepared using methanol and water and perform the screening of phytochemicals constituents present in the extract. Aqueous and methanol extract of mentha leaves c...

In this investigation, Aspergillus terreus NCFT4269.10 was employed in liquid static surface (LSSF) and solid state (SSF) fermentation to assess the optimal conditions for α-amylase biosynthesis. One-variable-at-a-time approach (quasi-optimum protocol) was primarily used to investigate the effect of each parameter on production of amylase. The maximum amylase production was achieved using pearl...

Staphylococcus aureus, a versatile human pathogen, is commonly associated with medical device infections. Its capacity to establish and maintain these infections is thought to be related to its ability to form adherent biofilms. In this study, commercially available α-amylase compounds from various biological sources were evaluated for their ability to reduce and prevent biofilm formation of se...

A bacterium, isolated from rabbit’s waste and identified as Cellulomonas sp., had cellulase and thermostable α-amylase activity when grown on wheat bran. Maximum activity of thermostable α-amylase was obtained by adding 3% soluble starch. However, soybean oil (1 ml l) could increase the production of α-amylase and cellulase in wheat bran. The α-amylase was characterized by making a demonstratio...
