We have studied the effects in three rodent models of generalised convulsive or absence epilepsy of two antagonists of group I metabotropic glutamate receptors that are selective for the mGlu1 receptor. LY 367385 ((+)-2-methyl-4-carboxyphenylglycine) and AIDA ((RS)-1-aminoindan-1,5-dicarboxylic acid) have been administered intracerebroventricularly (i.c.v.)(More)
In the present study we have examined the role of presynaptic group I metabotropic glutamate (mGlu) receptors in the control of neuronal glutamate release using rat forebrain slices pre-loaded with [(3)H]D-aspartate. We have also addressed the question of which group I mGlu receptor subtype, mGlu(1) or mGlu(5), mediates the facilitatory response observed by(More)
A recent emergence of Cryptococcus gattii in the Pacific Northwest involves strains that fall into three primarily clonal molecular subtypes: VGIIa, VGIIb and VGIIc. Multilocus sequence typing (MLST) and variable number tandem repeat analysis appear to identify little diversity within these molecular subtypes. Given the apparent expansion of these subtypes(More)
Previous studies have revealed that the combination of small doses of isradipine and naltrexone (ISR&NTX) blocks the ability of cocaine to enhance pressing for rewarding, lateral hypothalamic brain stimulation. Further, such combinations also reduce rats' intakes of alcoholic beverages. Here, we asked whether ISR&NTX would lose its ability to reduce the(More)
Nine closed head injured (CRI) children (mean age = 11.4 years) with post-onset intervals of seven months to eight years were studied. The CRI children ranged from mild-moderate to severely impaired. Nine normally developing children (mean age = 10.9 years) served as controls. An overt rehearsal free recall task was used. Subjects were instructed to "think(More)
Although many socialization agents influence children's behavior (D. L. Vandell, 2000), the evidence (e.g., from intervention studies) indicates that each exerts its influence only within its own domain. Context effects and genetic effects are among the confounding factors that make it impossible, given current data, to reject the null hypothesis of zero(More)
The role of group I metabotropic glutamate (mGlu) receptors in neurodegeneration is controversial because of the contradictory effects of mGlu1/5 agonists in in vitro models of neuronal cell death. In this study, novel and selective antagonists of mGlu1 and mGlu5: LY367385 and LY367366 were found to show consistent neuroprotective effects against(More)
Clonal VGII subtypes (outbreak strains) of Cryptococcus gattii have caused an outbreak in the US Pacific Northwest since 2004. Outbreak-associated infections occur equally in male and female patients (median age 56 years) and usually cause pulmonary disease in persons with underlying medical conditions. Since 2009, a total of 25 C. gattii infections, 23(More)
That endogenous retrovirus (ERV) is present within the placenta of humans and other mammals has been known for the past 25 years, but the significance of this observation is still not fully understood. Much molecular biological data have emerged in recent years to support the earlier electron microscopic data on the presence of placental ERV. The evidence(More)
BACKGROUND Cryptococcosis is a common opportunistic infection of human immunodeficiency virus (HIV)-infected individuals mostly occurring in resource-limited countries. This study compares the performance of a recently developed lateral flow immunoassay (LFA) to blood culture and enzyme immunoassay (EIA) for the diagnosis of cryptococcosis. METHODS(More)
