BACKGROUND The Pro12Ala polymorphism of the peroxisome proliferator-activated receptor-gamma2 (PPARgamma-2) gene has been variably associated with insulin resistance, obesity and type 2 diabetes in several populations. However, this association has not been studied in Iranian subjects and we hypothesized that this variation might be associated with insulin(More)
BACKGROUND Protein tyrosine phosphatase 1B (PTPN1) dephosphorylates insulin receptors and attenuates insulin signaling. Polymorphisms in the coding sequence of PTPN1 have been variably associated with type 2 diabetes (T2D). We hypothesized that variations within the PTPN1 promoter might contribute to the development of T2D and related metabolic traits. (More)
BACKGROUND Insulin resistance is a complex problem which may not always correlate with all its cardiovascular risk factors in various populations. We investigated the relationship between homeostasis model assessment of insulin resistance (HOMA-IR) with cardiovascular risk factors in Iranian subjects with normal fasting glucose (NFG) and normal glucose(More)
Cardiomyocyte loss in the ischemically injured human heart often leads to irreversible defects in cardiac function. Recently, cellular cardiomyoplasty with mesenchymal stem cells, which are multipotent cells with the ability to differentiate into specialized cells under appropriate stimuli, has emerged as a new approach for repairing damaged myocardium. In(More)
BACKGROUND Protein tyrosine phosphatase 1B (PTP1B), encoded by the PTPN1 gene, efficiently dephosphorylates the insulin receptor, and attenuates insulin signaling. Recently, a 1484insG variant of the PTPN1 gene has been associated with an increased risk of metabolic syndrome in an Italian population that has not been confirmed in the subsequent studies. The(More)
The locus coeruleus is involved in the regulation of the sense of pain. To demonstrate the changes in noradrenaline level in the locus coeruleus during the formalin test, a microdialysis probe was implanted into the left locus coeruleus of rats. Formalin was subcutaneously injected into the plantar surface of the right hind paw and pain ratings were(More)
The toxicity of available drugs for treatment of leishmaniasis, coupled with emerging drug resistance, make it urgent to find new therapies. Antimicrobial peptides (AMPs) have a strong broad-spectrum antimicrobial activity with distinctive modes of action and are considered as promising therapeutic agents. The defensins, members of the large family of AMPs,(More)
In this paper, a novel index is introduced for static and dynamic eccentricity fault diagnosis in permanent magnet synchronous motors (PMSMs). The proposed index is a linear combination of the energy, shape factor, peak, head angle of the peak, area below the peak, gradient of the peak of the detail signals in wavelet decomposition, and coefficients of the(More)
The aim of the present study is to investigate the cytokines induction by smooth lipopolysaccharides (S-LPS) extracted from Brucella melitensis (Rev1 vaccine strain) and Brucella abortus (a field isolate). These lipopolysaccharides were used to induce inflammatory cytokines production in peripheral blood cell culture of healthy individuals. Secretion of(More)
BACKGROUND Telomerase activity increases in cancer cells. Bcl-2 is an antiapoptotic factor that its concentration grows in many cancer cells including hepato-cellular carcinoma cells. In this study, an attempt was made to investigate the effects of a new synthetic compound, platinum azidothymidine (Pt-AZT) on treatment of rats with Hepatocellular Carcinoma(More)
