Cardiac Overexpression of S100A6 Attenuates Cardiomyocyte Apoptosis and Reduces Infarct Size After Myocardial Ischemia-Reperfusion.

Background: Cardiomyocyte-specific transgenic mice overexpressing S100A6, a member of the family of EF-hand calcium-binding proteins, develop less cardiac hypertrophy, interstitial fibrosis, and myocyte apoptosis after permanent coronary ligation, findings that support S100A6 as a potential therapeutic target after acute myocardial infarction. Our purpose was to investigate S100A6 gene therapy for acute myocardial ischemia-reperfusion.

Methods And Results: We first performed in vitro studies to examine the effects of S100A6 overexpression and knockdown in rat neonatal cardiomyocytes.

Prospect of ultrasound-mediated gene delivery in cardiovascular applications.

Introduction: The field of regenerative medicine has evolved over the years, investigating gene and stem/progenitor cell therapies to help address the increasing burden of cardiovascular disease (CVD). While the lack of success of gene therapy in clinical trials has dampened enthusiasm, the search continues for a successful and translatable gene therapy strategy for CVD. Ultrasound-mediated gene delivery (UMGD) is a non-invasive technique for gene delivery that utilizes gene-bearing carrier microbubbles and high power ultrasound to facilitate transfection in vivo.

Spontaneous pneumothorax in pregnancy: a case report.

Spontaneous pneumothorax is an extremely rare condition during pregnancy. Rupture of a subpleural apical bulla or blebs are the most common cause of spontaneous pneumothorax in young pregnant women. It is believed to be due to increase respiratory activity associated peripartum period.

Nanotechnology and nuclear medicine; research and preclinical applications.

The birth of nanotechnology in human society was around 2000 years ago and soon found applications in various fields. In this article, we highlight the current status of research and preclinical applications and also future prospects of nanotechnology in medicine and in nuclear medicine. The most important field is cancer.
