TNF and endothelial dysfunction: This study investigated biomarkers for glycemic control (hemoglobin A1c and random blood glucose), lipid metabolism (adiponectin, triglycerides, total cholesterol, high-density lipoprotein [HDL], and low-density lipoprotein [LDL]), systemic inflammation (high-sensitivity hs-CRP, TNF-alpha, and IL-6), endothelial dysfunction (sICAM-1 and sVCAM-1), and hepatic cholestasis (gamma-glutamyl transferase [GGT]) in Emirati schoolchildren.
