Adiponectin expression in human epicardial adipose tissue in vivo is lower in patients with coronary artery disease.

Background: Intra-peritoneal adipose tissue is recognized as a predictor of metabolic syndrome and may contribute to the risk for cardiovascular disease by the production of adipocytokines, including adiponectin. Nevertheless, there is no knowledge on whether other visceral depots of adipose tissue, including the epicardial fat, have any metabolically active role, including production of adiponectin.

Aim Of The Study: We sought to evaluate adiponectin protein expression in epicardial adipose tissue in vivo both in patients with severe coronary artery disease (CAD) and in subjects without CAD.

Detection of deleted mitochondrial DNA in Kearns-Sayre syndrome using laser capture microdissection.

A novel 4949-base pair mitochondrial DNA (mtDNA) deletion was detected in various tissues in a postmortem study of a patient with Kearns-Sayre syndrome (KSS). Deleted mtDNA levels were higher in skeletal muscle and brain and lower in kidney, working myocardium, and endocrine tissues (thyroid, parathyroids, pancreas, and adrenal glands). The distribution of the deletion in skeletal muscle and conducting myocardium was analyzed by means of laser capture microdissection (LCM).
