background: the modern dairy cows, due to intensive selection for higher milk production during past decades, have become more resistant to insulin. accompanied with dmi depression in per parturient dairy cow, insulin resistance may lead to a massive release of non-esterified fatty acids (nefa) to bloodstream which might act as a start point for development of other diseases. objectives: the pu...

insulin resistance syndrome, also referred to as the metabolic syndrome or syndrome x, refers to a constellation of common metabolic and cardiovascular disorders (e.g. obesity, type 2 diabetes mellitus, hypertension, and dyslipidemia), which are all cardiovascular risk factors. insulin resistance can be induced by fructose-rich diet in rats. we investigated the effect of vanadyl sulfate (0.2 mg...

Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited. ABSTRACT The armamentarium of therapeutics used to treat cancer patients relies heavily on ionizing radiation and chemotherapeutic drugs that severely damage DNA. The responses of tumor cells to these treatments is heavily influenced by their environment: physical contacts with structural eleme...

We develop a systematic theory of microwave-induced oscillations in magnetoresistivity of a 2D electron gas in the vicinity of fractional harmonics of the cyclotron resonance, observed in recent experiments. We show that in the limit of well-separated Landau levels the effect is dominated by the multiphoton inelastic mechanism. At moderate magnetic field, two single-photon mechanisms become imp...

Objective(s):Multidrug resistance (MDR) of cancer cells is a major obstacle to successful chemotherapy. Overexpression of breast cancer resistance protein (BCRP) is one of the major causes of MDR. In addition, it has been shown that PI3K/Akt signaling pathway involves in drug resistance. Therefore, we evaluated the effects of novel approaches including siRNA directed against BCRP and targeted t...

In order to examine radiation-induced proteins in an extremely radio-resistant bacterium, it became possibleto perform comparative proteomic analysis on radio-resistance Bacillus megaterium WHO as a wildtypestrain for the first time. Variation in cellular proteins profiles of the Bacillus megaterium WHO after 5KGy γ-irradiation were analyzed by two-dimensional poly acryl amide...

W e read with great interest the article by Lima-Martínez and cols. (1). They studied the relationship between epicardial adipose tissue (EAT) thickness and plasma levels of adiponectin in Venezuelan patients. And they found a significant association between EAT thickness and both metabolic syndrome components and adiponectin concentration. The authors also reported a strong correlation between...

principal function of insulin in the liver is to suppress glucose production when blood glucose concentrations increase. This process is impaired in hepatic insulin resistance and contributes to postprandial hyperglycemia. The development of hepatic insulin resistance is very closely linked to non alcoholic fatty liver disease (NAFLD), and is a major factor in the pathogenesis of type 2 diabete...
