BACKGROUND Postmortem and positron emission tomography (PET) studies have reported several alterations in serotonin 1A receptor (5-HT(1A)) binding parameters in patients with schizophrenia. This study examines 5-HT(1A) availability in vivo in individuals with schizophrenia and schizo-affective disorder. MATERIALS AND METHODS Twenty-two medication-free… (More)
BACKGROUND Triflusal is an antiplatelet agent that has shown clinical advantages when compared with aspirin in the secondary prevention of vascular events. TAPIRSS (Triflusal versus Aspirin for Prevention of Infarction: a Randomized Stroke Study) explored the efficacy and safety of triflusal in the secondary prevention of stroke in a Latin American… (More)
The aim of this study was to compare 5-HT(1A) availability in vivo in individuals with schizophrenia before and during treatment with the atypical antipsychotic ziprasidone. Six individuals with schizophrenia underwent two PET scans with [(11)C]WAY 100635; the first while medication-free (baseline) and the second while taking the atypical antipsychotic… (More)
Insulin-dependent diabetes mellitus is widely believed to be an autoimmune disease. Recent onset diabetics show destruction of insulin-secreting pancreatic beta-cells associated with a lymphocytic infiltrate (insulitis), with autoantibodies to beta-cells being found even before the onset of symptoms. Susceptibility to the disease is strongly influenced by… (More)
An adoptive transfer model of insulin-dependent diabetes mellitus (IDDM) in the nonobese diabetic mouse was used to examine the roles of alpha 4-integrin, vascular cell adhesion molecule 1 (VCAM-1); and intercellular adhesion molecule 1 (ICAM-1) in the pathogenesis of autoimmune diabetes. Antibodies specific for both alpha 4-integrin and one of its ligands,… (More)
Paralysis of the tongue due to isolated bilateral hypoglossal nerve palsy is a rare occurrence. Due to a trauma the cause in our case may have been a traction injury to both hypoglossal nerves at the base of skull. In some cases a contributing factor may be malformation of the skull base. Most cases have a good prognosis for recovery.
