blood sample was taken from all participants. Serum samples were disjoined from
the whole blood by centrifugation at 2606.8×g for 10 minutes
and were stored at —80°C before analysis. The fasting venous blood samples were
assembled in ethylenediaminetetraacetic acid-treated vacutainers to evaluate
fasting blood glucose and inflammatory indices.
Colorimetric enzymatic kit (Pars Azmoon Co.) was used for measuring fasting blood
glucose concentration. TNF-α was also measured using ELISA method by Orgenium
kit. In addition, hs-CRP concentration was determined by means of ELISA (via
Hitachi911 chemistry and immunoassay(Sentinel) analysis).
