...Ksenija D. Velickovic; Mirela M. Ukropina; Radmila M. Glisic; Maja M. Cakic-Milosevic ABSTRACT The aim of this study was to determine the effects of long-term sucrose overfeeding on functional capacity and ultrastructural characteristics of the rat brown adipose tissue (BAT). For the study, 16 male...
