IL-6 and TNF alpha secretion is increased by sleep loss or restriction. IL-6 secretion progressively increases with age, yet its association with decreased quality and quantity of sleep in old adults is unknown. This study examined the alteration of 24-h secretory pattern of IL-6, TNF alpha, and cortisol in 15 young and 13 old normal sleepers who were(More)
BACKGROUND The aim of this study was to develop a mathematical model of the hypothalamo-pituitary-gonadal axis that would reflect available data in humans. METHODS A model of hormonal relationships at the early follicular and midluteal phases of the human menstrual cycle is proposed. FINDINGS Two distinct temporal patterns of oscillatory behavior have(More)
BACKGROUND Hypothalamic synthesis and secretion of corticotropin-releasing hormone (CRH), a putative mediator of various behavioral and physiological responses to ethanol (EtOH), is defective in inbred Lewis (LEW) rats in comparison with their genetically related inbred Fischer 344 (F344) and outbred Sprague-Dawley (S-D) strains. We aimed to characterize(More)
Having reported that traumatic brain injury (TBI), produced by moderate lateral controlled cortical impact (CCI), causes long-term dysregulation of the neuroendocrine stress response, the aim of this study was to assess short- and long-term effects of both moderate and mild CCI on stress-induced hypothalamic-pituitary-adrenal (HPA) function. TBI was induced(More)
Contemporary Western medicine has witnessed a fragmentation of our conceptualization of the medical endeavor into 'traditional medicine' and 'non-traditional medicine'. The former is meant to refer to the Western medical tradition, the latter encompasses both 'complementary' and 'alternative' medical practices. Complementary medicine complements(More)
To evaluate the role of Hypothalamic-Pituitary-Adrenal (HPA) hormones and psychoneuroendocrine modulation on NK cell activity in Anorexia Nervosa (AN) we studied in 24 patients and 20 sex- and age-matched healthy controls, the spontaneous NK activity of peripheral blood mononuclear (PBM) cells and the susceptibility in vitro to cortisol or immune interferon(More)
Cytokines belonging to the so-called interleukin-6 (IL-6) or gp130 cytokine family, notably IL-6 and IL-11, are known as pro-resorptive cytokines, in that they promote osteoclastogenesis. Glucocorticoid (GC)-induced osteoporosis is admittedly the most frequent secondary osteoporosis. The pathogenesis still has many unresolved issues. Although the effects of(More)
The entrance of leptin into the central nervous system is of physiological relevance to the regulation of food intake, energy balance, and neuroendocrine function. To our knowledge, the relation between plasma and lumbar cerebrospinal fluid (CSF) leptin has not been examined across the 24-h period. To evaluate the relation between plasma and CSF leptin(More)
Shared decision making empowers patients as informed consumers, helping them to make clinical decisions that optimize their personal oral health. Evidence-based dentistry supports this process by providing best evidence that, when presented in visual and interactive formats, focuses consultation time on treatment or therapy options and their trade-offs.(More)
BACKGROUND Human and animal findings indicate that males and females display major differences in risk for and consequences of alcohol abuse and alcoholism. These differences are in large part mediated by sex-specific hormonal environments. Gonadal and adrenal secretory products are known to modulate the neurobehavioral responses of ethanol (EtOH)(More)
