Clozapine-induced myocarditis: role of catecholamines in a murine model.

Clozapine, an atypical antipsychotic, is very effective in the treatment of resistant schizophrenia. However, cardiotoxicity of clozapine, particularly in young patients, has raised concerns about its safety. Increased catecholamines have been postulated to trigger an inflammatory response resulting in myocarditis, dilated cardiomyopathy, and death, although this has not yet been thoroughly studied.

Propranolol ameliorates and epinephrine exacerbates progression of acute and chronic viral myocarditis.

Recent studies point to important interactions between proinflammatory cytokines and neurohumoral mediators in heart failure. Here we investigate the influence of the beta-adrenergic system on cytokines and neurohumoral factors and the sequelae of viral myocarditis. In an experimental model with virus-infected BALB/c mice, we studied the acute and chronic effects of epinephrine and propranolol on myocardial morphology, cytokine gene expression, and survival.

Cocaine enhances myocarditis induced by encephalomyocarditis virus in murine model.

This study was designed to investigate whether cocaine can exacerbate viral myocarditis and increase its incidence. Recent clinical evidence suggests that cocaine abuse increases the incidence of myocarditis. However, it has not been directly demonstrated that cocaine exposure enhances murine myocarditis.

Generation of physician-scientists manpower: a follow-up study of the first 294 graduates of the Harvard-MIT Program of Health Sciences and Technology.

Background: The MD program of the Harvard-MIT Division of Health Sciences and Technology was founded in 1970. One of its goals was the application of the academic resources of the two universities to the education of leaders in academic medicine and biomedical sciences.

Methods: The first MD class was admitted in 1971.
