Analysis of the extreme diversity of salivary alpha-amylase isoforms generated by physiological proteolysis using liquid chromatography-tandem mass spectrometry [PDF]

, 2012
Saliva is a crucial biofluid for oral health and is also of increasing importance as a non-invasive source of disease biomarkers. Salivary alpha-amylase is an abundant protein in saliva, and changes in amylase expression have been previously associated ...

Evaluation of Salivary and Serum Alpha Amylase Level in Dental Caries of Adolescence

Brazilian Dental Science, 2016
Objective: Some previous studies suggested a significant relationship between alpha- amylase, and caries formation. This study was implemented in order to investigate the interrelation between level of salivary and serum alpha- amylase and dental caries.

Salivary alpha-amylase as a stress biomarker in diseased dogs. [PDF]

J Vet Sci, 2019
Salivary alpha-amylase (sAA) is a stress biomarker in human diseases, but there are no reports of sAA measurements in diseased dogs. This study measured the sAA and serum alpha-amylase (AA) levels in 16 healthy dogs and 31 diseased dogs using a kinetic enzyme assay to assess the stress status.

Trends in waking salivary alpha-amylase levels following healing lucid dreams. [PDF]

Front Psychol
IntroductionSalivary alpha-amylase (sAA) is considered a marker of autonomic nervous system activity in stress research, and atypical waking sAA responses have been reported for traumatized individuals. Lucid dreams, characterized by a dreamer’s awareness of their dream state while remaining asleep, have shown promising preliminary evidence of their ...

A distinct sortase SrtB anchors and processes a streptococcal adhesin AbpA with a novel structural property. [PDF]

, 2016
Surface display of proteins by sortases in Gram-positive bacteria is crucial for bacterial fitness and virulence. We found a unique gene locus encoding an amylase-binding adhesin AbpA and a sortase B in oral streptococci.

Interparental aggression and parent–adolescent salivary alpha amylase symmetry [PDF]

Physiology & Behavior, 2010
The present study examined salivary alpha amylase (sAA), a putative marker of adrenergic activity, in family members engaging in family conflict discussions. We examined symmetry among family members' sAA levels at baseline and in response to a conflict discussion.

Usefulness of salivary alpha amylase as a biomarker of chronic stress and stress related oral mucosal changes ' a pilot study [PDF]

, 2014
Introduction: Salivary biomarkers are suggested to provide a reliable, noninvasive and objective measurement of chronic psychosocial stress and helps in assessment of pivotal role of stress in causation or precipitation of multitude of health problems ...

The relationship between the level of salivary alpha amylase activity and pain severity in patients with symptomatic irreversible pulpitis

Restorative Dentistry & Endodontics, 2013
Objectives Assessment of dental pain severity is very challenging in dentistry. Previous studies have suggested that elevated salivary alpha amylase may contribute to increased physical stresses.
