We investigated the pharmacology of three novel compounds, Org 27569 (5-chloro-3-ethyl-1H-indole-2-carboxylic acid [2-(4-piperidin-1-yl-phenyl)-ethyl]-amide), Org 27759 (3-ethyl-5-fluoro-1H-indole-2-carboxylic acid [2-94-dimethylamino-phenyl)-ethyl]-amide), and Org 29647 (5-chloro-3-ethyl-1H-indole-2-carboxylic acid (1-benzyl-pyrrolidin-3-yl)-amide,(More)
Vasopressin (AVP), produced in parvocellular neurons of the hypothalamic paraventricular nucleus, regulates, together with CRH, pituitary ACTH secretion. The pituitary actions of AVP are mediated through the G protein receptor V(1b) (V(1b)|R). In man, hyperactivity of the hypothalamic-pituitary-adrenal axis has been associated with depression and other(More)

Altered activity of the hypothalamic pituitary adrenal (HPA) axis is one of the most commonly observed neuroendocrine abnormalities in patients suffering from major depressive disorder (MDD). Altered cortisol secretion can be found in as many as 80% of depressed patients. This observation has led to intensive clinical and preclinical research aiming to(More)
Exposure to chronic restraint (CR) modifies the hypothalamic-pituitary-adrenal (HPA) axis response to subsequent acute stressors with adaptation of the response to a homotypic and sensitization of the response to a heterotypic stressor. Since vasopressin (AVP) activity has been reported to change during chronic stress, we investigated whether this was an(More)
The Oct transcription factors N-Oct-3 and N-Oct-5 are differentially expressed in normal melanocytes, melanoma tumors and cell lines. We have cloned the human brn-2 gene and have shown that it encodes both the N-Oct-3 and N-Oct-5 octamer binding activities detected in melanoma cells. The brn-2 genomic locus has been mapped to chromosome 6q16 and although(More)
To maintain optimum mechanical properties in glutaraldehyde-treated heart-valve tissue the full collagen crimp geometry originally present in the relaxed fresh tissue should be retained. By varying the pressure at which glutaraldehyde fixation is carried out, considerable alterations to this crimp geometry can be achieved. The mechanical stiffness of the(More)
It has been argued that hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis is a major biological abnormality in patients suffering from psychiatric conditions such as major depression. Both arginine vasopressin (AVP) and corticotrophin releasing factor (CRF) are responsible for stimulating the release of adrenocorticotropic hormone (ACTH) from(More)
The durability of the aortic homograft valve, when mounted in a rigid support frame, has been limited in some cases by aortic wall detachment from the frame in the commissure buttress area. To investigate the effects of frame flexibility, a stent was designed which was suitable for canine aortic valves of selected sizes. Of the two materials tested, acetal(More)
We investigated the effect of the glucocorticoid receptor (GR) antagonist Org 34850 on fast and delayed inhibition of corticosterone secretion in response to the synthetic glucocorticoid methylprednisolone (MPL). Male rats were implanted with a catheter in the right jugular vein, for blood sampling and MPL administration, and with an s.c. cannula for Org(More)
