Regulation of the peroxisome proliferator-activated receptor-γ (PPAR-γ) gene plays an important role in controlling the metabolism of lipids and inflammatory processes. Therefore, it can be associated with the pathogenesis of metabolic syndrome (MetS). The purpose of this study was to determine the expression of this gene in peripheral blood mononuclear cells (PBMC) in patients with metabolic syndrome. Using real-time polymerase chain reaction (PCR), mRNA expression of PPAR-γ was found in PBMC from 37 subjects with MetS and 30 healthy controls. Serum levels of glucose and lipid profiles were measured. The total antioxidant capacity (TAC) was measured using the ferric reducing ability of plasma (FRAP) test. Malondialdehyde (MDA) was determined using a fluorimetric method. Total oxidant status (TOS) in serum was assayed according to oxidation of ferric to ferrous in the presence of methyl orange. Super oxide dismutase (SOD) activity was measured using a Randox kit. Expression of PPAR-γ gene was significantly increased in patients with MetS compared to the control subjects (p=0.002). There was no difference in serum levels of TAC, MDA and SOD between the two study groups, but a significant difference was observed in the TOS (p=0.03). Serum levels of triglycerides and glucose were significantly higher in subjects with MetS. According to the results of our study, an increase in the expression of PPAR-γ in subjects with MetS indicated a possible role of PPAR-γ in the pathogenesis of this disease.

The Co–Ni/Al2O3 catalysts prepared using impregnation procedure, were used for the Fischer–Tropsch synthesis. The effect of calcination conditions of the catalyst as well as reactor situation was studied. It was found that the catalyst calcined at 550 8C for 6 h in air atmosphere has shown the best catalytic performance for CO hydrogenation. The best operational conditions were obtained as following:T = 350 8C, P = 1 atm and H2/CO = 2/1.

Purpose: The present study aimed to determine the prevalence of childhood obesity and overweight in Iranian children under 5 years of age using a systematic review and meta-analysis. Methods: We searched MEDLINE (PubMed), Web of Science, Google Scholar, Scopus, CINHAL, and the Iranian databases, including Scientific Information Database (www.sid.ir), Iranian Research Institute for Information Science and Technology (Irandoc.ac.ir), Iranmedex (www.iranmedex.com), and Magiran (www.magiran.com), for all articles published between January 1989 and August 2017. Sources of heterogeneity were determined using subgroup analysis and meta-regression. Results: Six articles were ultimately included in the meta-analysis to estimate the pooled prevalence, based on which the prevalence of obesity and overweight were estimated to be 8% (95% confidence interval [CI], 6%-10%) and 9% (95% CI, 7%-11%), respectively. The results of the subgroup analysis showed that the prevalence of obesity in boys and girls was 9% (95% CI, 6%-13%) and 7% (95% CI, 4-10%), respectively, and the prevalence of overweight in boys and girls was 10% (95% CI, 5%-15%) and 9% (95% CI, 5%-13%), respectively. Conclusion: Despite high heterogeneity among the results of the articles included in the meta-analysis, the prevalence of obesity and overweight is higher in Iranian children under 5 years of age. Therefore, parents and the health system must pay more attention to the lifestyle, nutritional habits, and physical activity of these children.
