BACKGROUND AND PURPOSE Predicting stroke using biomarkers would enable clinicians to help prevent stroke or mitigate damage. Several stroke biomarkers have been investigated but none has shown near term predictive value. METHODS We studied patients presenting with a history of stroke or transient ischemic attack (TIA) to determine whether serum levels of(More)
People are very likely to start psychoactive drug use during adolescence, an earlier onset being associated with a higher risk of developing addiction later in life. In experiment I, Pre- (postnatal day (pnd) 23-35), Mid- (pnd 36-48), or Post- (pnd 49-61) adolescent mice underwent a restricted-drinking period (2 h/day for 12 days), one bottle containing(More)
The interactions existing between substance P- and dopamine-positive neurons, notably in the basal ganglia, suggest that substance P may have therapeutic use in treatment of Parkinson's disease characterized by impaired dopaminergic transmission. The effects of intracerebroventricularly administered substance P were tested on the levels of dopamine and its(More)
Several groups of brain receptors are involved in the mechanisms underlying the development of opiate addiction, but the interactions occurring between these neuroreceptors and the immune system, including potential autoimmune responses, remain poorly understood. We studied in rats the effects of repeated administration of different psychotropic drugs on(More)
BACKGROUND AND PURPOSE The goal of this study was to compare the predictive ability of S100B, N-methyl-D-aspartate (NMDA) receptor antibodies (NR2Ab) and C-reactive protein (CRP) for neurological deficits after cardiac surgery with cardiopulmonary bypass (CPB). METHODS We investigated 557 high-risk adult patients who underwent coronary artery or valve(More)
BACKGROUND The acute assessment of patients with suspected ischemic stroke remains challenging. The use of brain biomarker assays may improve the early diagnosis of ischemic stroke. The main goal of the study was to evaluate whether the NR2 peptide, a product of the proteolytic degradation of N-methyl-D-aspartate (NMDA) receptors, can differentiate acute(More)
The effects of central administration of substance P (SP) on alcohol consumption and dopamine metabolism in the projections of the mesocorticolimbic and nigrostriatal systems of the brain were studied in chronically alcoholic rats. Rats received 15% ethanol solution for 6 months without choice. Intraventricular administration of SP (1 microg/rat) decreased(More)
We have analyzed the serum from patients with refractory epilepsy for the presence of autoreactive antibodies to AMPA glutamate receptor subunits. The presence and the level of autoantibodies were assessed using immunoblot and ELISA with synthetic peptides specific for subregions of AMPA glutamate receptor subunits. Patients with refractory epilepsy(More)
We have monitored EEG spontaneous spiking activity and analyzed serum from rats with cobalt-induced epilepsy for the presence of autoreactive antibodies to alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA) glutamate receptor subunits. The presence and the level of autoantibodies were assessed using immunoblot and ELISA with synthetic peptide(More)
BACKGROUND Possible interactions between nervous and immune systems during opioid addiction remain elusive. Recombinant mu-delta opioid receptors (MDOR) and the glutamate receptor 1 (GluR1) subunit of amino-3-hydroxy-5-methyl-4-isoxazole propionic acid glutamate receptors are involved in acute and chronic effects of morphine. Elevated levels of(More)
