Modern strategies of platinum resistance overcoming in patients with the serous ovarian cancer

The study was aimed to determine the platinum-resistance biomarkers in patients with ovarian cancer. The expression of ABCA1 is higher in platinum-resistant cases of ovarian cancer. The most pronounced relationship exists between the values of survivin expression, local activity of nitric oxide, the expression of glutathione dependent enzymes, the content of catecholamines in erythrocytes, and the expression of ABCA1 transporter

Thermal entanglement and efficiency of the quantum Otto cycle for the su(1,1) Tavis-Cummings system

The influence of the dynamical Stark shift on the thermal entanglement and the efficiency of the quantum Otto cycle is studied for the su(1,1) Tavis-Cummings system. It is shown that the degree of the thermal entanglement becomes larger as the dynamical Stark shift increases. In contrast, the efficiency of the Otto cycle is degraded with an increase of the values of dynamical Stark shift. Expressions for the efficiency coefficient are derived. Using those expressions we identify the maximal efficiency of the quantum Otto cycle from the experimentally measured values of the dynamical Stark shiftComment: to appear in J.Phys.

Nodal Analysis of Circuits Containing Current Conveyors

A special method of the nodal analysis of the circuits containing several types of the multiport current conveyors is presented in this paper. The method is based on the given regular and homogeneous models of the irregular current conveyors by the gyrators. Then a diakoptic solving and modification of the inversion of the admittance matrix is applie
