Aim – to analyze the peculiarities of asthenic manifestations in patients with type 2nd diabetes mellitus (DM) in clinical and psychological perspective. Materials and methods. We examined in 543 patients with type 2nd DM. The first clinical group (CG-1) was 57 patients with type 2nd DM of mild severity; the average age in the group was (51,80±1,28) years. The second clinical group (CG-2) made up of 312 patients with type 2nd DM, moderate severity; mean age in the group was (55,10±1,12) years. The third clinical group (CG-3) included 174 patients with type 2nd DM, severe degree of severity; the average age in the group was (61.80±0,85) years. Research methods: clinical-anamnestic, clinical-psychopathological, statistical. Results. The marked prevalence of asthenic syndrome in patients wath type 2nd DM 52,30%, which is almost half among all surveyed type 2nd DM. Discovered the direct correlation of asthenic symptoms with the severity of the type 2nd DM (rs = 0.4033, p<0.01). The factors in the risk of asthenic syndrome in patients with type 2nd DM was installed, among them is dominated by a moderate and severe degree of type 2nd DM, combined with obesity 2 degrees, DEP II degree, ischemic heart disease, heart failure, degenerative dystrophic lesions of the spine. Established that there is a direct correlation asthenic syndrome to the severity of type 2nd DM, as well as the accompanying somatic pathology. Established dominance in CG-1 and CG-2 component fatigue "mental fatigue" and CG-3 component "physical fatigue".Conclusions. Features of asthenic manifestations in patients with type 2nd DM in clinical and psychological perspective were investigated. The detection rate of asthenic manifestations among patients with type 2nd DM and the factors for their amplification were established. The organic etiology of asthenic manifestations have been proven; presentation about the stages of development of asthenic symptoms in patients with type 2nd DM were improved

The article treats off the morphology of the larvae of Common Spadefoot Toad inhabiting Volyn and Chernihiv Polissia. The span of analysis extended from the moment of their mass leaving the jelly envelopes up to the end of metamorphosis. The article studies the structure of the sucker and mouthparts, dynamics of larvae’s linear parameters. The achieved results testify to the absence of significant differences in the said species’ larvae’s structure of the sucker and mouthparts, as well as their linear parameters’ dynamics.Работа выполнена на кафедре экологии и охраны природы ЧНПУ им.

Unfolding and unzipping of single-stranded DNA by stretching

We present a theoretical study of single-stranded DNA under stretching. Within the proposed framework, the effects of basepairing on the mechanical response of the molecule can be studied in combination with an arbitrary underlying model of chain elasticity. In a generic case, we show that the stretching curve of ssDNA exhibits two distinct features: the second-order "unfolding" phase transition, and a sharp crossover, reminiscent of the first-order "unzipping" transition in dsDNA. We apply the theory to the particular cases of Worm-like Chain (WLC) and Freely-Joint Chain (FJC) models, and discuss the universal and model--dependent features of the mechanical response of ssDNA. In particular, we show that variation of the width of the unzipping crossover with interaction strength is very sensitive to the energetics of hairpin loops. This opens a new way of testing the elastic properties of ssDNA.Comment: 7 pages, 4 figures, substantially revised versio

Vortices in Spatially Inhomogeneous Superfluids

We study vortices in a radially inhomogeneous superfluid, as realized by a trapped degenerate Bose gas in a uniaxially symmetric potential. We show that, in contrast to a homogeneous superfluid, an off-axis vortex corresponds to an anisotropic superflow whose profile strongly depends on the distance to the trap axis. One consequence of this superflow anisotropy is vortex precession about the trap axis in the absence of an imposed rotation. In the complementary regime of a finite prescribed rotation, we compute the minimum-energy vortex density, showing that in the rapid-rotation limit it is extremely uniform, despite a strongly inhomogeneous (nearly) Thomas-Fermi condensate density $\rho_s(r)$. The weak radially-dependent contribution ($\propto \nabla^2\ln\rho_s(r)$) to the vortex distribution, that vanishes with the number of vortices $N_v$ as $\frac{1}{N_v}$, arises from the interplay between vortex quantum discretness (namely their inability to faithfully support the imposed rigid-body rotation) and the inhomogeneous superfluid density. This leads to an enhancement of the vortex density at the center of a typical concave trap, a prediction that is in quantitative agreement with recent experiments (cond-mat/0405240). One striking consequence of the inhomogeneous vortex distribution is an azimuthally-directed, radially-shearing superflow.Comment: 22 RevTeX pages, 20 figures, Submitted to PR

Biomarkers of platinum resistance in 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 transporte

Effects of Kinks on DNA Elasticity

We study the elastic response of a worm-like polymer chain with reversible kink-like structural defects. This is a generic model for (a) the double-stranded DNA with sharp bends induced by binding of certain proteins, and (b) effects of trans-gauche rotations in the backbone of the single-stranded DNA. The problem is solved both analytically and numerically by generalizing the well-known analogy to the Quantum Rotator. In the small stretching force regime, we find that the persistence length is renormalized due to the presence of the kinks. In the opposite regime, the response to the strong stretching is determined solely by the bare persistence length with exponential corrections due to the ``ideal gas of kinks''. This high-force behavior changes significantly in the limit of high bending rigidity of the chain. In that case, the leading corrections to the mechanical response are likely to be due to the formation of multi-kink structures, such as kink pairs.Comment: v1: 16 pages, 7 figures, LaTeX; submitted to Physical Review E; v2: a new subsection on soft kinks added to section Theory, sections Introduction and Conclusions expanded, references added, other minor changes; v3: a reference adde

РАСЧЕТ МАГНИТНОГО ПОЛЯ ТРЕХФАЗНЫХ КАБЕЛЬНЫХ ЛИНИЙ ПРИ ДВУСТОРОННЕМ ЗАМЫКАНИИ СОБСТВЕННЫХ ЭКРАНОВ КАБЕЛЕЙ, ОХВАЧЕННЫХ ФЕРРОМАГНИТНЫМИ СЕРДЕЧНИКАМИ

In this paper we obtain compact expressions for the magnetic field shielding factor of a high-voltage three-phase cable line consisting of single-core cables with two-point bonded cable shields and ferromagnetic cores installed. To obtain these expressions we develop the analytical model of the cable line. Following assumptions are made to develop the model: the current distribution in each cable shield is uniform, cylindrical ferromagnetic cores covering the cables are not magnetized to saturation and their magnetic permeability is constant, each of the ferromagnetic cores is magnetized only by the core current and the shield current of the cable that it covers, the magnetic field inside ferromagnetic cores is axisymmetric, the magnetic field is plane-parallel over the entire cable line. We consider common cases of flat and trefoil cable lines. The proposed expressions for the magnetic field shielding factor are verified experimentally. The physical model is made of three cables of the type NA2XSF(L)2Y-110 1´240/70. It is shown that the difference between numerical simulation results and experimental data lays within 15 %.Получены компактные соотношения для расчета эффективности экранирования магнитного поля высоковольтной трехфазной кабельной линии, состоящей из одножильных кабелей, которые охвачены ферромагнитными сердечниками, при двустороннем замыкании собственных экранов.
