Opportunities and options for surrogate assessment of insulin resistance

The high prevalence of type 2 diabetes mellitus (T2DM) and atherosclerotic cardiovascular diseases (CVD) determines the need for early detection and correction of key markers of cardio-metabolic risk (CMR). This prophylactic direction is closely related to metabolic syndrome (MS) based on the concept of insulin resistance (IR). At the same time, IR is the first link in the pathogenesis of T2DM and is a recognized risk factor for atherothrombosis. Therefore, early diagnosis of IR is of practical importance both for the detection of early disorders of carbohydrate metabolism (DCM) and prognosis of T2DM, and cardiological risk. Alternative indicators have been proposed for evaluating IR with the inclusion of lipid and anthropometric parameters, the diagnostic and prognostic significance of which in terms of CMR (DCM and CVD) has been evaluated in randomized clinical trials in comparison with the HOMA-IR index and clamp. The TyG index (calculated on the basis of plasma glucose and triglycerides) is consistent with the phenomenon of glucolipotoxicity with subsequent metabolic disorders in target organs. Its derivatives are proposed: TyG-WC (TyG / waist circumference) and TYG-BMI (TyG / BMI). Apply LAP indices (lipid accumulation index) and VAI (visceral obesity index), as well as TG / HDL (TG / HDL). Their ethnic and gender differences were revealed, attempts were made to calculate the cut-off points for these indices

Solvent effect on the activation volume of the diels-alder reaction between tetracyanoethylene and trans, trans-1,4-diphenyl-1,3-butadiene

The effect of increased hydrostatic pressure on the rate of the Diels-Alder reaction of tetracyanoethylene with trans, trans-1,4-diphenyl-1,3-butadiene at 25°C was studied to estimate the reaction volume and to show that it considerably varies with π-donor properties of the medium

Effect of external pressure and solvent on the equilibrium constant of the Diels-Alder reaction of 9-chloroanthracene with tetracyanoethylene

The effect of external pressure and solvent on the equilibrium constant of the Diels-Alder reaction of tetracyanoethylene with 9-chloroanthracene at 25°C was studied. The molar reaction volume is strongly solvent-dependent, cm3/mol: -11.3±1.0 in ο-xylene, -14.9±1.0 in toluene, -20.6±1.5 in 1,2-dichloroethane, -22.6±1.5 in ethyl acetate, and -24.2±1.5 in acetonitrile

Influence of Concrete Creep on the Bending of a Prestressed Bridge Beam

By present time significant experimental and theoretical material on concrete creep has been accumulated. At the same time, the known approaches to calculation of concrete and reinforced concrete structures with regard to creep are oriented mainly to solving problems with relatively simple geometry of the product. Moreover, there are no mechanic-mathematical models of hereditary type oriented to the finite-element method.The concept of modelling of long-term deformation of reinforced concrete structures in a three-dimensional statement, based on the use of the integral deformation modulus of concrete, does not allow one to carry out designing considering the technological prehistory. Therefore, the problem of developing a finite-element algorithm and corresponding software allowing the modelling of the volumetric stress-strain state of large-span prestressed reinforced concrete structures within the framework of the theory of hereditary aging is relevant

Volume, enthalpy and entropy of activation of the diels-alder reaction of dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate with 1-hexene

Pressure and temperature effects on the reaction rate of dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate with 1-hexene were investigated. The activation volume (-26.7 cm3 mol1, 298.1 K) is in agreement with the conservation of all four nitrogen atoms in transition state. Densitometry, 1H NMR and calorimetric studies of the reaction indicate nitrogen molecule loss by the intermediate just after its formation. Partial molar volumes in acetone of diene (127.2), 1-hexene (127.6) and the resulting adduct (206.9 cm3 mol-1) were determined

Solvent effect on the heat of solution and partial molar volume of some non-electrolytes and lithium perchlorate

For several non-electrolytes and for lithium perchlorate the solvent effect on the heat of solution and partial molar volumes was studied. In the absence of the donor-acceptor and electrostatic interactions, clear proportionality can be seen only in the alkane solutions and these changes are defined by the non-alkane component. For solutions of π-acceptor (tetracyanoethylene) and v-acceptor (gallium chloride) in the presence of π,π-, π,V- and n,v-complexes, the relation between the changes of interaction energy and the values of the partial molar volumes can be seen. The maximum change in the value of partial molar volumes (up to 50cm mo1-1) was noted for lithium perchlorate in ten solvents. The volume change is proportional to the compressibility coefficients of the solvents and correlates less with the values of heat of solution and solvent permittivity.

Integral assessment of the enterprise investment attractiveness: Testing the hypothesis of non-conformity to investor's interests

© Medwell Journals, 2017. The study attempts to improve the construction of a dynamic model for assessing the investment attractiveness of the enterprise. The researchers use the calculation of the Kendall correlation coefficient for two rank series by comparing the actual order of the growth rates of investment appeal indices with the standard ones based on internal environment indicators of a leading chemical enterprise. The researchers calculate the dynamic assessment of investment attractiveness. The study emphasizes that the maximum value of the dynamic assessment of investment attractiveness is equal to one in the case when all observed characteristics conform to the interests of potential investors. To test the null hypothesis about the statistical insignificance of the Kendall correlation coefficient the "tau" statistics and the calculation of the critical values of the Kendall rank correlation coefficient were used. The researchers employed an applied statistical analysis of the company's internal environment indicators for the dynamic assessment of investment attractiveness. In future, this technique will help researchers formulate unified approaches to assessing investment attractiveness by systemizing both internal and external factors based on the structure of the relationships between them

Effect of Elevated External Pressure on the Rate of the Diels-Alder Reaction of 9-Methylanthracene with Acrylonitrile, Catalyzed by Gallium Chloride

External pressure was found to similarly affect the rate of a gallium chloride-catalyzed Diels-Alder reaction between 9-methylanthracene with acrylonitrile and a noncatalyzed reaction of 9,10-dimethyl-anthracene with acrylonitrile. The observation of equal activation volumes is consistent with the assumption that elevated pressure very weakly affects the bond energy in the n,v complex of acrylonitrile with gallium chloride
