Nociceptin/orphanin FQ, N/OFQ, and its receptor NOP represent a non-opioid branch of the opioid superfamily that were first studied for their effects on pain responses. Both N/OFQ and NOP are involved in a wide range of 'non-pain' responses including immunomodulation and cardiovascular control. There is now growing interest in this system in inflammation and sepsis, which is the focus of this r...

Central nociceptin/orphanin FQ (N/OFQ)-expressing neurones are abundantly expressed in the hypothalamus and limbic system and are implicated in the regulation of activity of the hypothalamic-pituitary-adrenal axis (HPA) and stress responses. We investigated the role of the endogenous N/OFQ receptor (NOP) system using the nonpeptidic NOP antagonist, JTC-801 [N-(4-amino-2-methylquinolin-6-yl)-2-(...

BACKGROUND Peripheral blood mononuclear cells (PBMC) transcribe mRNA for the nonclassical opioid nociceptin/orphanin FQ (N/OFQ) receptor (NOP). We probed for the N/OFQ precursor, pre-pro-N/OFQ (ppN/OFQ). METHODS Using PBMC from 10 healthy volunteers we probed for ppN/OFQ using polymerase chain reaction (PCR) based experimental paradigms. RESULTS In gel-based PCR, we detected amplicons consi...

Inspection of the genome of the ligninolytic basidiomycete Phanerochaete chrysosporium revealed an unusual peroxidase_like sequence. The corresponding full length cDNA was sequenced and an archetypal secretion signal predicted. The deduced mature protein (NoP, novel peroxidase) contains 295 aa residues and is therefore considerably shorter than other Class II (fungal) peroxidases, such as ligni...

The opioid-like peptide, nociceptin/Orphanin FQ (N/OFQ), produces marked cardiovascular and renal responses following central or peripheral administration in rats. Due to their ability to behave as full/partial agonists or antagonists in different cellular and tissue assays, the present studies were performed to determine how compounds classified as N/OFQ peptide (NOP) receptor partial agonists...

The aim of the study was to investigate the in vitro and in vivo pharmacological profile of cebranopadol, a novel agonist for opioid and nociceptin/orphanin FQ (N/OFQ) receptors (NOP). In vitro cebranopadol was assayed in calcium mobilization studies in cells coexpressing NOP or opioid receptors and chimeric G-proteins and in a bioluminescence resonance energy transfer (BRET) assay for studying...

The Odd-Even (OE) [5] routing strategy has greatly improved the degree of adaptiveness over other adaptive routing strategies. It depends on an efficient selection strategy to achieve the potential performance of the improved adaptiveness. Asica et al. [3] proposed a NoP selection strategy, which aims to make use of such adaptiveness. However, there exists deficiency when applying it with the O...

We present a simple, yet effective, approach to Semi-Supervised Learning. Our approach is based on estimating density-based distances (DBD) using a shortest path calculation on a graph. These Graph-DBD estimates can then be used in any distancebased supervised learning method, such as Nearest Neighbor methods and SVMs with RBF kernels. In order to apply the method to very large data sets, we al...
