Influência do fumo na atividade da amilase salivar e na curva glicêmica [2010]

Blood serum amylase may be measured for purposes of medical diagnosis. The small sample size precludes generalization of findings to other populations. The present salviar found no correlation between sAA and salivary flow rate and no correlations between cortisol and salivary flow rates measured in pregnant and non-pregnant women, which confirms that neither cortisol nor sAA levels are amilaee altered as a function of salivary flow rate. The correlation that exists between starch consumption and number of AMY1 copies specific to population suggest that more AMY1 copies in high starch populations has been selected for by natural selection and considered the favorable phenotype for those individuals.

In the pregnant group, first-trimester samples were collected between gestational weeks 11 and 16; second-trimester samples, between gestational weeks 18 and 22; and third-trimester samples, between weeks 32 and This offers strong evidence that natural selection has acted on this gene as opposed to the possibility that the gene has spread through genetic drift.

All participants underwent an intraoral examination, interview and history-taking, and blood and UWS collection in each trimester of pregnancy for pregnant participants and during the follicular and luteal phases amulase the menstrual cycle for non-pregnant participants. Salivary cortisol testing has been used to assess hypothalamic-pituitary-adrenal HPA axis function under various cognitive conditions and in the presence of stress and anxiety 67.

These factors have driven extensive research into this testing modality 1 – 3including validation studies of quantitation of a variety of organic and inorganic compounds in saliva 4. Retrieved 27 March The interrelatedness between serum and salivary cortisol levels in non-pregnant women and men appears to be the same.

Hence, it was enrolled 26 participants. During pregnancy, baseline salivary cortisol concentrations exhibit a constant increase starting around gestational week 25; by term, levels are over twice as high as those detected in non-pregnant women 8. There were no differences in median UWS flow rate values between pregnant and non-pregnant subjects 0. Human salivary alpha-amylase reactivity in a psychosocial stress paradigm.

Parotid saliva cortisol in normal subjects: Although salivary free cortisol has been proposed as a useful parameter for assessment of slaivar function, an appropriate biomarker that reflects sympathoadrenal medullary activity has yet to be found.

In addition, authors have confirmed that sAA measurement can be performed without assessment of salivary flow, as the latter does not interfere with sAA activation 22 Serum cortisol levels, however, were higher in pregnant versus non-pregnant women. Recent studies have highlighted the utility of sAA as a marker of physical, psychological, or psychosocial stress induced by activation of the autonomic nervous system, which controls the salivary glands 1315 – Allosteric regulation Cooperativity Enzyme inhibitor Enzyme activator.
