Use-dependent N-methyl-d-aspartate receptor (NMDAR) antagonists produce behaviors in human volunteers that resemble schizophrenia and exacerbate those behaviors in schizophrenic patients, suggesting that hypofunction of NMDAR-mediated neuronal circuitry may be involved in the etiology of clinical schizophrenia. Activation of the metabotropic glutamate(More)
Group II mGlu receptor agonists (eg LY379268 and LY354740) have been shown to reverse many of the behavioral responses to PCP as well as glutamate release elicited by PCP and ketamine. In the present set of experiments, we used in vivo microdialysis to show that, in addition to reversing PCP- and ketamine-evoked glutamate release, group II mGlu receptor(More)
Herein we disclose the discovery of a new class of positive allosteric potentiators of the metabotropic glutamate receptor 2 (mGlu2), phenyl-tetrazolyl acetophenones, e.g. 1-(2-hydroxy-3-propyl-4-[4-[4-(2H-tetrazol-5-yl)phenoxy]butoxy]phenyl) ethanone (4). These potentiators were shown to have no effect in the absence of glutamate as well as no effect at(More)
Some atypical antipsychotic drugs appear to improve cognitive function in schizophrenia and since acetylcholine (ACh) is of importance in cognition, we used in vivo microdialysis to examine the effects of antipsychotics administered acutely (SC or IP) at pharmacologically comparable doses on ACh outflow in the hippocampus of the rat. The atypical(More)
The effects of the selective cannabinoid CB(1) receptor antagonist N-(piperidin-1-yl)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole-3-carboxamide-hydrochloride (SR141716A) on extracellular concentrations of norepinephrine and 5-hydroxytryptamine (5-HT) were assessed by in vivo microdialysis in the anterior hypothalamus of freely moving(More)
Metabotropic glutamate receptor 2 (mGluR2) has been implicated in a variety of CNS disorders, including schizophrenia. Disclosed herein is the development of a new series of allosteric potentiators of mGluR2. Structure-activity relationship studies in conjunction with pharmacokinetic data led to the discovery of indole 5, which is active in an animal model(More)
We have identified and synthesized a series of phenyl-tetrazolyl and 4-thiopyridyl indanones as allosteric potentiators of the metabotropic glutamate receptor 2. Structure activity relationship studies directed toward improving the potency and level of potentiation, as well as PK properties, led to the discovery of 28 (EC50=186 nM), which displayed activity(More)
INTRODUCTION Female fertility is commonly described as the biological nature of women, yet different meanings emerge when one takes a holistic approach to fertility while considering varying contexts and perspectives. An improved understanding of female fertility will enhance health care professionals' understanding of female fertility and improve(More)
This review of literature describes the behaviors of hospitalized children with autism spectrum disorder (ASD) that health care providers find challenging. It also identifies strategies used to address these challenging behaviors. The systematic review of literature identified 34 articles from databases on health care of challenging behaviors of children(More)
BACKGROUND The aim was to compare the efficacy and acceptability of two Internet-supported fertility-awareness-based methods of family planning. STUDY DESIGN Six hundred and sixty-seven women and their male partners were randomized into either an electronic hormonal fertility monitor (EHFM) group or a cervical mucus monitoring (CMM) group. Both groups(More)
