BACKGROUND The pathophysiological mechanism causing awakening blood pressure (BP) rise is not clear. CASE REPORT We report the case of a 66-year-old man with a history of spinal cord injury, and who had remarkable awakening BP rise in ambulatory BP monitoring. The patient also had orthostatic hypotension and post-prandial hypotension associated with an increased insulin level. This case sugge...

Objective: Hard envelope of date palm pollen is used as a sedative and calmative compounds in Iranian traditional medicine. We tried to study the effects of Phoenix dactylifera (Tarooneh) extract on sleep time and Brian waves. Materials and Methods: Rats were divided into control and test groups in sleep experiment. Control groups included intact group (without any injection), negative control ...

Hypothalamic-pituitary-adrenal (HPA)-axis dysregulation is a prominent finding in more severe Major Depressive Disorder (MDD), and is characterized by increased baseline cortisol levels at awakening (BCL), blunted cortisol awakening response (CAR) and increased area under the cortisol curve (AUC). Selective serotonin reuptake inhibitors (SSRIs) appear to normalize HPA-axis dysfunction, but this...

BACKGROUND Few electroencephalography (EEG) data are available in anaesthetized infants. This study aimed to identify EEG characteristics that might warn of awakening (AW) from sevoflurane anaesthesia in infants. METHODS Twenty intubated infants [aged 39-77 weeks post-menstrual age (PMA)] were studied after surgery during sevoflurane wash-out. EEG was recorded at the end of surgery and throug...

Police officers are required to work irregular hours, which induces stress, fatigue, and sleep disruption, and they have higher rates of chronic disease and mortality. Cortisol is a well-known "stress hormone" produced via activation of the hypothalamic-pituitary-adrenal axis. An abnormal secretion pattern has been associated with immune system dysregulation and may serve as an early indicator ...

Psychobiological research on aging in humans has been confounded by individual differences that have not been adequately characterized in the literature. This paper is an attempt to shed light on this issue by examining the impact of social network characteristics predictive of successful aging on salivary cortisol among 78 older Chinese people in Hong Kong. Eight salivary cortisol samples were...

BACKGROUND Psychological disorders arising from bullying at work (BW) are common. The relationship between these disorders and putative markers is not well established. AIMS To measure saliva dehydroepiandrosterone sulphate (DHEAS) and saliva cortisol as putative markers in individuals suffering from BW. METHODS Forty one subjects suffering from BW were screened for mental distress at the i...

BACKGROUND Some studies have found an association between elevated cortisol and subsequent depression, but findings are inconsistent. The cortisol awakening response may be a more stable measure of hypothalamic-pituitary-adrenal function and potentially of stress reactivity. AIMS To investigate whether salivary cortisol, particularly the cortisol awakening response, is associated with subsequ...

The effect of daily work stress on the next morning's awakening cortisol level was determined in a sample of 124 mothers (M age = 49.89, SD= 6.33) of adolescents and adults with developmental disabilities and compared to 115 mothers (M age = 46.19, SD = 7.08) of individuals without disabilities. Mothers participated in 8 days of diary telephone interviews and provided saliva samples. Multilevel...
