Fro Po Ca Me Am Te con Lis Yo Ma BACKGROUND The effectiveness of beta-blockers for preventing cardiac events has been questioned for patients who have coronary heart disease (CHD) without a prior myocardial infarction (MI). OBJECTIVES The purpose of this study was to assess the association of beta-blockers with outcomes among patients

A patient with atrial tachycardia presented with dyspnoea on exertion. Transoesophageal echocardiography revealed idiopathic left atrial appendage stenosis. The mouth of the atrial appendage was narrowed, and there was a high velocity to and fro jet between the left atrial body and the left atrial appendage. The study, therefore, suggested isolated left atrial appendage orifice stenosis.

In an attempt to develop gene therapy for thyroid carcinomas, the present studies were undertaken to evaluate in vitro and in vivo therapeutic efficacy and toxicity of herpes simplex virus thymidine kinase (HSV-tk) gene and ganciclovir (GCV) treatment, a widely used prodrug/suicide gene therapy, in human thyroid carcinoma cell lines, FRO and WRO cells, using a means of retrovirus-mediated gene ...

Formalin-fixed paraffin-embedded (FFPE) tissue samples represent a potentially invaluable resource for transcriptomic-based research into the molecular basis of disease. However, use of FFPE samples in gene expression studies has been limited by technical challenges resulting from degradation of nucleic acids. Here we evaluated gene expression profiles derived from fresh-frozen (FRO) and FFPE m...

Background: A critical aspect of the NIH Translational Research roadmap, which seeks to accelerate the delivery of “bench-side” discoveries to patient’s “bedside,” is the management of the provenance metadata that keeps track of the origin and history of data resources as they traverse the path from the bench to the bedside and back. A comprehensive provenance framework is essential for researc...
