The salivary alpha-amylase concentration in patients with rheumatoid arthritis: A case–control study

Dental Research Journal, 2023
Background: Rheumatoid arthritis (RA) is one of the most common chronic inflammatory diseases. Previous studies have reported an association between stress and salivary alpha-amylase. The aim of this study was to investigate the concentration of salivary

RNAseq analysis of Cellvibrio japonicus during starch utilization differentiates between genes encoding carbohydrate active enzymes controlled by substrate detection or growth rate

Microbiology Spectrum, 2023
Bacterial utilization of starch is increasingly of interest as the importance and contributions of animal gut microbiomes become more defined. Consequently, identifying and characterizing the bacterial enzymes responsible for the degradation, transport ...

Assessment of child's dental anxiety/fear and stress during dental treatment: a systematic review by CEDACORE [PDF]

Brazilian Oral Research, 2022
: There is a lack of evidence on the correlation between salivary biomarkers and subjective measures of dental fear and anxiety in children. This systematic review aimed to retrieve the scientific evidence comparing the results of dental anxiety measured

The optimized production, purification, characterization, and application in the bread making industry of three acid-stable alpha-amylases isoforms from a new isolated Bacillus subtilis strain US586.

Journal of food biochemistry, 2019
A new alpha-amylase-producing strain was assigned as Bacillus subtilis US586. The used statistical methodology indicated that amylase production was enhanced by 5.3 folds.

Impact of calcium on salivary α-amylase activity, starch paste apparent viscosity and thickness perception [PDF]

, 2011
Thickness perception of starch-thickened products during eating has been linked to starch viscosity and salivary amylase activity. Calcium is an essential cofactor for α-amylase and there is anecdotal evidence that adding extra calcium affects ...

Toward a More Comprehensive View of α-Amylase across Decapods Crustaceans

Biology, 2021
Decapod crustaceans are a very diverse group and have evolved to suit a wide variety of diets. Alpha-amylases enzymes, responsible for starch and glycogen digestion, have been more thoroughly studied in herbivore and omnivore than in carnivorous species.

Identification and optimization of PrsA in Bacillus subtilis for improved yield of amylase

Microbial Cell Factories, 2019
Background PrsA is an extracytoplasmic folding catalyst essential in Bacillus subtilis. Overexpression of the native PrsA from B. subtilis has repeatedly lead to increased amylase yields.

The spectrum of low molecular weight alpha-amylase/protease inhibitor genes expressed in the US bread wheat cultivar Butte 86

BMC Research Notes, 2011
Background Wheat grains accumulate a variety of low molecular weight proteins that are inhibitors of alpha-amylases and proteases and play an important protective role in the grain. These proteins have more balanced amino acid compositions than the major
