The proinflammatory cytokines, TNFalpha and IL-6, are elevated in obstructive sleep apnea (OSA) and have been proposed as mediators of excessive daytime sleepiness in humans. We tested the effects of etanercept, a medication that neutralizes TNFalpha and is approved by the FDA for the treatment of rheumatoid arthritis, in eight obese male apneics. These(More)
Sleep loss has been associated with increased sleepiness, decreased performance, elevations in inflammatory cytokines, and insulin resistance. Daytime napping has been promoted as a countermeasure to sleep loss. To assess the effects of a 2-h midafternoon nap following a night of sleep loss on postnap sleepiness, performance, cortisol, and IL-6, 41 young(More)
Corticotropin-releasing hormone (CRH), a hypothalamic neuropeptide, is also produced in the human endometrium where it participates in local inflammatory phenomena associated with the decidualization of endometrial stroma and the implantation of the fertilized egg. The inflammatory cytokines interleukin 1 (IL-1), IL-6 and leukemia inhibitory factor (LIF)(More)
BACKGROUND Interleukin-6 (IL-6) secretion is suppressed by glucocorticoids and stimulated by catecholamines. Patients with posttraumatic stress disorder (PTSD) have decreased cortisol and increased catecholamine secretion. The purpose of this study was to assess the relation of IL-6 levels and hypothalamic-pituitary-adrenal and noradrenergic activity in(More)
In human endometrium, both epithelial and stroma cells produce corticotropin-releasing hormone (CRH). Both types of cells also possess specific CRH-binding sites indicating a local effect of endometrial CRH. The transcription of the CRH gene in human endometrium is under the control of steroid hormones and locally produced prostanoids and interleukins.(More)
The corticotropin-releasing hormone (CRH) family, CRH, CRH-related peptides and their receptors (R) play major roles in coordinating the behavioral, endocrine, autonomic, and immune responses to stress. The wide influence of the CRH system on physiologic processes in both brain and periphery implicates the respective peptides in the pathophysiology of(More)
Corticotropin-releasing hormone (CRH), its natural homologs urocortins (UCN) 1, 2, and 3, and several types of CRH receptors (R), coordinate the behavioral, endocrine, autonomic, and immune responses to stress. The potential use of CRH antagonists is currently under intense investigation. Selective antagonists have been used experimentally to clarify the(More)
BACKGROUND Few studies have examined the relation between alexithymia (i.e. the inability to recognize and verbalize emotions) and professional burnout. Considering the absence of relevant studies in the Greek scientific literature, the aim of this work was to examine the associations of alexithymia with the three facets of professional burnout, the(More)
Corticotropin-releasing hormone (CRH) is expressed in several peripheral tissues, including normal epithelial cells of the human and rodent uterus. However, the biological role of endometrial CRH is known in neither species. As a first step to clarify this role, we studied the regulation of CRH promoter in endometrial cells. We performed homologous(More)
Human endometrium exhibits characteristics of a neuroendocrine-like stress organ in addition to its classical role as the main target of ovarian steroid hormones. Indeed, the epithelial cells of human endometrium express the stress-associated neuropeptide genes corticotropin-releasing hormone (CRH), proopiomelanocortin, proenkephalin and prodynorphin.(More)
