Lifetime stress, blood pressure, heart rate, and salivary cortisol levels in post-menopausal women
… first was to assess the effects of past stress levels on blood pressure (BP), heart rate (HR), and salivary cortisol excretion in post-menopausal women. The second purpose of this study was to examine the interactions between the hypothalamic-pituitary-adrenal (HPA) axis and the cardiovascular …

The Effect of an Acute Bout of Rock Climbing on Cognitive Functioning and Cortisol Levels
… outcomes, cognitive performance and salivary cortisol levels were assessed by the Stroop test. A linear mixed-effects model was used to examine the differences between cognition and cortisol before and after the interventions in control and climbing groups. Reaction times and salivary cortisol …

THREE SPEEDS OF YOGA AND THE EFFECTS ON SALIVARY CORTISOL LEVELS IN FEMALE NURSING STUDENTS
… which are associated with chronically elevated cortisol levels due to the excessive firing of the Hypothalamic Pituitary Adrenal (HPA) axis. This study assessed three speeds of yoga and how they acutely affected salivary cortisol levels within female nursing students. <strong>Methods</strong>: …

Effect of Blood Volume Manipulations and Warm Acclimation on Cortisol Levels in the Antarctic Teleost Trematomus bernacchii
… activity. The renin-angiotensin system (RAS) and cortisol have been shown to increase drinking rate and gill Na+, K+-ATPase activity in fish, therefore regulating water and ion balance. Moreover, the RAS has been shown to increase cortisol levels in fish. Therefore, experiments were designed to …

Mindfulness-Based Stretching and Deep Breathing Exercises Normalize Serum Cortisol Levels and Reverse Symptoms of PTSD: A Prospective Randomized-Controlled Trial
Context: Cortisol, the human glucocorticoid, plays a key role in the pathophysiology of posttraumatic stress disorder (PTSD). It is known that individuals with chronic PTSD suffer from low basal cortisol levels. Endogenic normalization of basal cortisol concentration through exercise may have a …

Effect of hot-iron branding on the cheek or upper hind limb on cortisol levels, behaviour and production in feedlot calves
… 60, 90 and 120 minutes after branding for serum cortisol determination with a commercial radioimmunoassay kit. In addition, faeces were collected from all animals on the day after arrival, as well as at day seven, two and one prior to branding, on the day of branding and for seven consecutive …

The Relationship Between Salivary Cortisol Levels and Stressful Behaviors upon the Introduction of a New Exhibit Mate in Captive Black and Gold Howler Monkeys (<i>Alouatta caraya</i>) at the Hattiesburg Zoo
<p>Salivary cortisol levels were taken on a male and a female howler monkey and compared with behavioral observations during their introduction to one another into an exhibit at the Hattiesburg Zoo in order to determine the link between behavior and stress. This study sought to answer the following …

Role of cortisol in social and memory impairments in individuals with velocardiofacial syndrome (VCFS)
… some evidence to suggest that the stress hormone cortisol contributes to social, cognitive, and communication deficits in related populations (Corbett, Schupp, Levine, & Mendoza, 2009). This study investigated the role that cortisol has on the social and cognitive impairments observed in children …

System identification of cortisol secretion : characterizing pulsatile dynamics
Cortisol controls the body's metabolism and response to inflammation and stress. Cortisol is released in pulses from the adrenal glands in response to pulses of adreno-corticotropic hormone (ACTH) released from the anterior pituitary; in return, cortisol has a negative feedback effect on ACTH …

The Use of Hair Cortisol as a Biomarker of Chronic Stress in Patients with a recent Acute Myocardial Infarction
… Since an MI is a stressful life event, plasma cortisol levels are expected to increase significantly from the baseline. Cortisol and dehydroepiandrosterone (DHEA) as products of the hypothalamicpituitary-adrenal (HPA)-axis have been used to diagnose endocrine disorders in serum, urine and …
