BACKGROUND & OBJECTIVES TNF-α is an adipocytokine that has been implicated in the development of insulin resistance. Dysregulation of TNF-α production has been implicated in a variety of human diseases including type 2 diabetes mellitus. We aimed to find out the association of TNF-α levels with insulin resistance, body mass index and waist hip ratio; and to elicit its role with respect to durat...

We aimed to investigate associations of the dietary inflammatory index (DII) with glucose-insulin homeostasis markers, and the risk of glucose intolerance. This cross-sectional study included 2975 adults from the Tehran Lipid and Glucose Study. Fasting plasma glucose (FPG), 2-h post-load glucose (2h-PG), and fasting serum insulin were measured. Homeostatic model assessment of insulin resistance...

We explored whether the combination of anti-oxidant and anti-inflammatory guava (Psidium guajava) and trehalose treatment protects the kidney and pancreas against Type II diabetes (T2DM)-induced injury in rats. We measured the active component of guava juice by HPLC analysis. T2DM was induced in Wistar rats by intraperitoneal administration of nicotinamide and streptozotocin and combination wit...

Objective. To examine the different impacts of MS components on insulin resistance in type 2 diabetes. Methods. A number of subjects (144) who met the criteria of (1) age between 30 and 75 years, (2) had type 2 diabetes for more than one year, and (3) taking gliclazide and metformin for more than 6 months were enrolled. All subjects were assigned to one of the four HOMA index categories. The HO...

Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder among women of reproductive age, characterized by hormonal imbalance and insulin resistance. D-chiro-inositol, a naturally occurring inositol isomer, has been suggested as potential treatment option for PCOS. This study aimed to investigate the effects D-chiro-inositol supplementation on parameters, resistance in with Methods...

Results For the IR assessed by the clamp, the HOMA-AD demonstrated a stronger coefficient of correlation (r=0.64) compared with the HOMA-IR (r=-0.56); p<0.0001. In the ROC analysis, compared with the HOMA-IR, the HOMA-AD showed higher values of the AUC for the identification of IR based on the clamp test (AUC: 0.844 vs. AUC: 0.804) and on the metabolic syndrome (AUC: 0.703 vs. AUC: 0.689), resp...

AIM Weight loss reduces risk factors associated with obesity. However, long-term metabolic improvement remains a challenge. We investigated quantitative gene expression of subcutaneous adipose tissue in obese individuals and its relationship with low calorie diet and long term weight maintenance induced changes in insulin resistance. RESEARCH DESIGN Three hundred eleven overweight and obese i...

BACKGROUND There are few studies that investigated the correlation between insulin resistance (IR) and the coronary artery remodeling. The aim of the study is to investigate the association of IR measured by homeostasis model assessment of insulin resistance (HOMA-IR) and coronary artery remodeling evaluated by intravascular ultrasound (IVUS). METHODS A total of 298 consecutive patients who r...

OBJECTIVE To evaluate circulating E-selectin levels in patients with nonfunctional adrenal incidentaloma (NFA) in relation to insulin resistance and early atherosclerosis. SUBJECTS AND METHODS A total of 40 patients with NFA (mean [SD] age: 55.6 [10.7] years; 70% were females) and 35 controls (mean [SD] age: 51.5 [8.1] years; 71.4% were females) selected from age-, gender- and body mass index...
