Prenatal diagnosis of intrauterine premature closure of the ductus arteriosus following maternal diclofenac application.

We report a case of prenatal diagnosis of premature closure of the ductus arteriosus following maternal diclofenac therapy at 35 weeks of gestation. Fetal echocardiography at 37 weeks of gestation revealed a dilated right ventricle with moderate tricuspid regurgitation, pulmonary insufficiency and complete closure of the ductus arteriosus. Immediate Cesarean section resulted in an excellent neonatal outcome.

Identification of cardiac myosin peptides capable of inducing autoimmune myocarditis in BALB/c mice.

Immunization with cardiac myosin induces T cell-mediated myocarditis in genetically predisposed mice and serves as a model for autoimmune heart disease. This study was undertaken to identify pathogenic epitopes on the myosin molecule. Our approach was based on the comparison of the pathogenicity between cardiac (alpha-)myosin and soleus muscle (beta-)myosin.
