The renal patient with coronary artery disease: current concepts and dilemmas.

abstract：OBJECTIVES:In this study, our goal was to determine if human resistin plays a role in regulating the uptake of atherogenic low-density lipoproteins in human hepatocytes. BACKGROUND:Serum levels of resistin, an adipose tissue-derived adipokine, are increased in human obesity and are positively correlated with atheroscl...
