OBJECTIVES: this study was aimed at comparing dental stress in children having their first dental visit to those returning for dental treatment using salivary biomarkers of stress including salivary cortisol (s-cortisol), Immunoglobulin-A (s-IgA) and alpha-amylase (s-α-amylase). Additionally, the study was aimed at monitoring the change in stress in new patients as they progressed from the waiting to the clinical areas. STUDY DESIGN: salivary samples were collected from 40 children who had not been to a dentist before and similar samples were collected from 40 children who were returning for completion of dental treatment...

OBJECTIVE: Passive smoking leads to melanin pigmentation on gingiva. However, documentation of gingival pigmentation and salivary amylase activity in passive smokers relative to the duration of exposure to environmental tobacco smoke (ETS), is incomplete and requires further investigation. Thus, this study aimed to assess effects of ETS exposure on gingival pigmentation in young adults. In addition, to correlate a number of years of exposure to an extent, the intensity of gingival pigmentation and salivary amylase activity...

Primary Sjögren's syndrome (pSS) is an autoimmune exocrinopathy in which the role that the immune response plays in reducing exocrine gland function, including the glandular microenvironment of cytokines, has not been fully understood. Epithelial cells from biopsies of human parotid gland (HPG) were used to establish a model of human salivary gland in vitro. In this model, the functional consequences of several proinflammatory soluble factors present in the pSS glandular microenvironment were assessed. Stimulation with isoproterenol and calcium produced a significant increase in the basal activity of amylase in the HPG cell supernatants...

The effect of working on-call from home on sympatho-adrenal medullary (SAM) system activity is currently unknown. This study had two aims, Aim 1: examine salivary α-amylase awakening response (AAR) and diurnal salivary α-amylase (sAA) profile in fire and emergency service workers who operate on-call from home following a night on-call with a call (NIGHT-CALL), a night on-call without a call (NO-CALL) and an off-call night (OFF-CALL) and, Aim 2: explore whether there was an anticipatory effect of working on-call from home (ON) compared to when off-call (OFF) on the diurnal sAA profile...

The comparative structure and expression of salivary components and vesicular transport proteins in the canine major salivary glands were investigated. Histochemical analysis revealed that the morphology of the five major salivary glands-parotid, submandibular, polystomatic sublingual, monostomatic sublingual, and zygomatic glands-was greatly diverse. Immunoblot analysis revealed that expression levels of α-amylase and antimicrobial proteins, such as lysozyme, lactoperoxidase, and lactoferrin, differed among the different glands...

Deirdre A Katz, Melissa K Peckins
Intraindividual variability in stress responsivity and the interrelationship of multiple neuroendocrine systems make a multisystem analytic approach to examining the human stress response challenging. The present study makes use of an efficient social-evaluative stress paradigm - the Group Public Speaking Task for Adolescents (GPST-A) - to examine the hypothalamic-pituitary-adrenocortical (HPA)-axis and Autonomic Nervous System (ANS) reactivity profiles of 54 adolescents with salivary cortisol and salivary alpha-amylase (sAA)...

Parental stress is an important risk factor for child maltreatment (CM) perpetration. Evidence-based, parent-training programs can decrease CM perpetration risk and reduce self-reported parental stress; however, little is known about how such programs impact physiological stress correlates. In this quasi-experimental pilot study, maternal biobehavioral responses were measured in response to SafeCare®, an evidence-based program targeting CM, often implemented by social workers in child welfare settings. Maternal participants (N = 18) were recruited to complete SafeCare and repeated within-subject assessments pre- and post-intervention...

PURPOSE: Fetal programming is the idea that environmental stimuli can alter the development of the fetus, which may have a long-term effect on the child. We have recently reported that maternal prenatal cortisol predicts infant negative emotionality in a sex-dependent manner: high prenatal cortisol was associated with increased negative emotionality in females, and decreased negative emotionality in males. This study aims to test for this sex-specific effect in a different cohort, and investigate whether sex differences in fetal programming may be specific to glucocorticoid mechanisms by also examining a maternal salivary alpha-amylase (sAA) by sex interaction...

Salivary markers have been proposed as noninvasive and easy-to-collect indicators of dehydrations during physical exercise. It has been demonstrated that threshold-based classifications can distinguish dehydrated from euhydrated subjects. However, considerable challenges were reported simultaneously, for example, high intersubject variabilities in these markers. Therefore, we propose a machine-learning approach to handle the intersubject variabilities and to advance from binary classifications to quantitative estimations of total body water (TBW) loss...

CONTEXT: Cranial Electrotherapy Stimulation (CES) is a safe modulation of brain activity for treating depression, anxiety, insomnia, and pain. However, there are no published studies in patients with advanced cancer (ACP). OBJECTIVES: The aim of the study was to determine the feasibility and preliminary efficacy of a 4-week CES intervention on depression, anxiety, sleep disturbance, and pain scores. Concurrent salivary biomarker studies were conducted. METHODS: In this one group open label pre- and post-intervention study with a 4-week CES intervention, ACP's with one or more of four moderate intensity (≥3/10) ESAS symptoms (depression, anxiety, sleep disturbance, and pain) were eligible...

Emotional eating (EE) corresponds to a change in eating behavior in response to distress and results in an increase of food intake (overeating (EOE)) or in food avoidance (undereating (EUE)). EE has been related to temperament (i.e. negative emotionality) and dysregulated stress biomarkers in school-aged children; parenting has been understood to influence this relationship in older children. The aim of the study was to investigate to which extent stress biomarkers and negative emotionality are related to EE and to understand the role of parenting in this relationship...

Salivary cortisol (sCort) and salivary alpha-amylase (sAA) constitute proxy measures of the two major stress response systems, i.e. the hypothalamic-pituitary-adrenal axis and the autonomic nervous system, respectively. Potentially confounding determinants of sCort and sAA may limit a reliable concurrent measurement of both biomarkers, if not adequately considered. We reviewed the most important determinants of sCort and sAA and provide recommendations for handling these potential confounders. We focused on a selection of potential confounders, resulting in an in-depth consideration of age, sex steroid-related factors, somatic health, acute medication, smoking, consumption of food and drinks, alcohol consumption, physical activity/fitness, and sleep...

BACKGROUND: Current models explaining motor functional neurological disorders (FND) integrate both the neurobiological mechanisms underlying symptoms production and the role of psychosocial stressors. Imaging studies have suggested abnormal motor control linked to impaired emotional and stress regulation. However, little is known on the biological stress regulation in FND. Our aim was to study the biological and perceived response to stress in patients with motor FND. METHODS: Sixteen patients with motor FND (DSM-5 criteria) and fifteen healthy controls underwent the Trier Social Stress Test...

At the time of school-age, the most frequent stress stimuli are related to school environment and educational process. Anxiety may play a big role in coping with stressful situations associated with school load. To approach this issue, we performed a real-life study at school during the classwork. The sample consisted of 36 healthy children aged 10 years, which were divided to low and high trait anxiety group based on the median value of the anxiety score. The investigations were carried out in the classroom during a stress condition (final exams) and non-stress condition (without any exam)...

Previous studies have reported the failure of cognitive emotion regulation (CER), especially in regulating unpleasant emotions under stress. The underlying reason for this failure was the application of CER depends heavily on the executive function of the prefrontal cortex (PFC), but this function can be impaired by stress-related neuroendocrine hormones. This observation highlights the necessity of developing self-regulatory strategies that require less top-down cognitive control. Based on traditional Chinese philosophy and medicine, which examine how different types of emotions promote or counteract one another, we have developed a novel emotion regulation strategy whereby one emotion is used to alter another...

Stress causes an increase in cortisol and amylase. Recurrent aphthous stomatitis (RAS) results due to a multitude of causes, amongst which stress is one of the most important. Aim of the study was to estimate the level of stress, serum cortisol, salivary cortisol, amylase and electrolytes in subjects with RAS. 34 subjects with RAS (cases) were compared with 34 controls. Stress was measured using state trait anxiety inventory (STAI). Serum cortisol (Radioimmunoassay), Salivary cortisol, amylase (ELISA) and electrolytes (Flame photometry) were measured...

For the current study, we developed and tested a biopsychological model to combine research on psychological tension, the Limited Capacity Model of Motivated Mediated Message Processing, and the endocrine system to predict and understand how people process anti-drug PSAs. We predicted that co-presentation of pleasant and unpleasant information, vs. solely pleasant or unpleasant, will trigger evaluative tension about the target behavior in persuasive messages and result in a biological response (increase in cortisol, alpha amylase, and heart rate)...

BACKGROUND: Salivary alpha-amylase (sAA) is considered a biomarker of sympathetic activation in humans, but there is controversy regarding the existence of sAA in dogs. The hypothesis of this study was that sAA exists in dogs and it could change in situations of sympathetic stimulation. Therefore, the aims of this study were: 1) to demonstrate the presence of alpha-amylase in saliva of dogs by Western-Blot, 2) to validate an spectrophotometric method for the measurement of sAA activity and 3) to evaluate the possible changes in sAA activity after the induction of an ejaculation in dogs which is known to produce a sympathetic activation...

OBJECTIVE: Flower arrangement program (FAP) horticultural therapy promotes psychological, social and physiological wellness and recovery. Moreover, FAPs have been used to evaluate the outcomes related to visuospatial working memory; yet, most of these studies used subjective outcome measures such as behavioural observations and questionnaires. Few studies report objective evaluations of FAP effects in humans. In the present study, we measured the effects of an FAP task on frontal lobe activity in healthy participants using near-infrared spectroscopy...

The aim of this study was to investigate the effects of Ixeris dentata (IXD) extract to improve the salivation rate in dry mouth induced by diabetes. Both control and diabetic rats were treated with a sublingual spray of either water or IXD extract to determine the effects of IXD on salivation. During the study, we observed that IXD extract treatment increased the salivary flow rate in diabetic rats. The expression of α-amylase was increased significantly in both saliva and glandular tissue lysates of IXD-treated diabetic rats...
