A recently identified neuropeptide with PRL-releasing capabilities binds to and activates a previously known orphan G protein-coupled receptor, GPR10. We initiated a study to define the pharmacology of the peptide/receptor interaction and to identify the distribution of the peptide and its receptor in the central nervous system to elucidate sites of action(More)
RATIONALE The molecular mechanisms involved in airway oxidative stress responses reported in healthy smokers and in those with chronic obstructive pulmonary disease (COPD) are poorly understood. OBJECTIVES To assess the expression of genes involved in oxidative stress responses in the bronchial epithelium of smokers with or without COPD and in relation to(More)
1 1-[4-(3-piperidin-1-yl-propoxy)-benzyl]-piperidine (JNJ-5207852) is a novel, non-imidazole histamine H3 receptor antagonist, with high affinity at the rat (pKi=8.9) and human (pKi=9.24) H3 receptor. JNJ-5207852 is selective for the H3 receptor, with negligible binding to other receptors, transporters and ion channels at 1 microm. 2 JNJ-5207852 readily(More)
While homomers containing 5-HT(3A) subunits form functional ligand-gated serotonin (5-HT) receptors in heterologous expression systems (Jackson, M. B., and Yakel, J. L. (1995) Annu. Rev. Physiol. 57, 447-468; Lambert, J. J., Peters, J. A., and Hope, A. G. (1995) in Ligand-Voltage-Gated Ion Channels (North, R., ed) pp. 177-211, CRC Press, Inc., Boca Raton,(More)
Studies of the correlation of subjective and objective sleep measures in depressed patients have produced mixed results so far. Further, they were carried out in sleep laboratories and tended to obtain one-off assessments, thus not taking into account the effect of treatment. We investigated forty (40) patients over the course of 8-week treatment of(More)
We investigated the functional connectivity of brain regions activated during opiate craving. Previously we used recorded autobiographical scripts to induce opiate craving in 12 abstinent opiate-dependent subjects while they were undergoing positron emission tomography (PET) scanning using the regional cerebral blood flow (rCBF) tracer H2 15O. SPM99 was(More)
Alcohol produces many subjective and objective effects in man including pleasure, sedation, anxiolysis, plus impaired eye movements and memory. In human volunteers we have used a newly available GABA-A/benzodiazepine receptor inverse agonist that is selective for the alpha5 subtype (a5IA) to evaluate the role of this subtype in mediating these effects of(More)
Although Th-2-mediated inflammation is a key therapeutic target in asthma, its relationship to altered structure and functions of the airways is largely unknown. In addition to inflammation, asthma is a disorder involving the airway epithelium that is more vulnerable to environmental injury and responds to this by impaired healing. This establishes a(More)
Although autonomic function has been investigated in panic disorder (PD), previous studies have not used non-invasive beat by beat blood pressure (BP) monitoring to assess the rapid dynamics of BP during autonomic reflex tests. The hypothesis of the current study was that patients with PD would show increased cardiovascular sympathetic reactivity compared(More)
BACKGROUND Epidemiological studies have demonstrated adverse health effects of environmental pollution. Diesel exhaust (DE) is a major contributor to particulate matter pollution. DE exposure has been shown to induce a pronounced inflammatory response in the airways, together with an enhanced epithelial expression of cytokines such as IL-8, Gro-alpha, IL-13(More)
