Saliva is one of the important body fluids that reflects normal internal characteristics and
disease state of an individual. As a multi-composition oral fluid, has high potential for the …

The internally driven 24-h cycle in humans, called circadian rhythm, controls physiological,
metabolic, and hormonal processes, and is tied to the circadian clocks ticking in most of the …

Sleep disorders are commonplace in our modern societies. Specialized hospital
departments are generally overloaded, and sleep assessment is an expensive process in …

Winter and summer seasons are contrasted by light/dark conditions at temperate latitudes,

Objective To synthesise the literature examining the autonomic nervous system (ANS) and
cortisol responses to an acute stressor following total sleep deprivation (TSD) in healthy …

This paper describes an approach for colorimetric detection of salivary α-amylase, one of the
potential biomarkers of autonomic nervous system (ANS) activity, for enabling assessment of …

This study aimed to examine the effect of acute exogenous melatonin administration on
salivary cortisol and alpha‐amylase (sCort and sAA) as representatives of the HPA axis and …

Objective: This study aimed to evaluate sleep behaviors among college students, to assess
salivary alpha-amylase (sAA) and heart rate variability (HRV) in association with stress, and …

Background: Clinical studies have established mastication as a stress relaxation behavior in
humans. Absence of teeth compromises mastication, increasing psychologic stress in …
