Salivary Vip Concentrations Are Elevated In Humans After Acute Stress, Giovanni Ventre
Salivary Vip Concentrations Are Elevated In Humans After Acute Stress, Giovanni Ventre
Seton Hall University Dissertations and Theses (ETDs)
The purpose of this research was to evaluate two salivary neuropeptides in the context of the stress response. The research was focused first and foremost on evaluating the usefulness of salivary Neuropeptide Y (NPY) and salivary vasoactive intestinal peptide (VIP) as stress indicators. Secondly, we questioned whether these markers help us in distinguishing between physical and psychological stress. Psychological stress can be experienced in a situation such as that in anticipation of an important exam or mental task. Physical stress can be experienced usually by strenuous exercise. Salivary NPY and salivary VIP are two neuropeptides that are released as a …
The Effect Of Circadian Rhythm On Cortisol And Perceived Stress Correlations, Adam Bender
The Effect Of Circadian Rhythm On Cortisol And Perceived Stress Correlations, Adam Bender
Honors Theses
Stress is a known trigger of the Hypothalamus-Pituitary-Adrenal (HPA) Axis which leads to the production and secretion of the catabolic steroid cortisol by the adrenal gland. Since cortisol production is affected by stress, it follows that a high self-perception of stress would be correlated with high blood and saliva cortisol levels. Literature generally shows a gap in identifying this correlation, perhaps because of the interconnected nature of endocrine pathways. New experimental methods that control for the effects of circadian rhythm have shown limited success in demonstrating this correlation. Our purpose is to continue exploring the relationship between cortisol, perceived stress, …
