    The article presents a literature review over the last few years devoted to the health status and development peculiarities of children born using assisted reproductive technologies (ART) procedures. The statistics shows an explosive increase in the frequency of ART application as a fertility treatment method. The presented data analysis reflects the perinatal outcomes after ART in children, the frequency of congenital malformations and genetic diseases in this population, possible long-term malconditions and pathologies in children born using ART. The overwhelming majority of investigators consider the adverse effect of ART on a child’s body to be the result of prematurity and multiple pregnancy (transfer multiple embryos followed by partial reduction). It is stated that the widespread introduction of ART may contribute to the vertical transmission of parental infertility factors in the population. The application of ART procedures in some cases is associated with controversial ethical and legal issues (surrogacy, oocyte donation). Further improvements in ART procedures (preimplantation training, medical and genetic diagnosis, reducing the frequency of multiple pregnancy) cannot be stated as an alternative to the general medical and social prevention of reproductive disorders in adolescents and youth.Β Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ прСдставлСн Π°Π½Π°Π»ΠΈΠ· Π΄Π°Π½Π½Ρ‹Ρ… Π»ΠΈΡ‚Π΅Ρ€Π°Ρ‚ΡƒΡ€Ρ‹ послСдних Π»Π΅Ρ‚, посвящСнной особСнностям состояния Π·Π΄ΠΎΡ€ΠΎΠ²ΡŒΡ ΠΈ развития Π΄Π΅Ρ‚Π΅ΠΉ, Ρ€ΠΎΠ΄ΠΈΠ²ΡˆΠΈΡ…ΡΡ с ΠΏΠΎΠΌΠΎΡ‰ΡŒΡŽ Π²ΡΠΏΠΎΠΌΠΎΠ³Π°Ρ‚Π΅Π»ΡŒΠ½Ρ‹Ρ… Ρ€Π΅ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ‚ΠΈΠ²Π½Ρ‹Ρ… Ρ‚Π΅Ρ…Π½ΠΎΠ»ΠΎΠ³ΠΈΠΉ (Π’Π Π’).

    This study is dedicated to investigation of serotoninergic structures that activate motility of the stomach. Experiments were performed on 94 Wistar rats under general anesthesia, mechanical ventilation, bilateral vagotomy and transection of both glossopharyngeal nerves. Mechanical activity of the stomach was recorded during serotonin adipanate infusion to intact animals and on the background of the ongoing actions of cholinergic and adrenergic antagonists. The blockade of adrenergic and cholinergic receptors does not prevent, but contrary, increase stimulatory effect of serotonin. Ξ²-adrenergic blockade increases the intensity of observed reactions almost up to 90%. Conclusion: both adrenergic and cholinergic mechanisms provide inhibitory pattern on serotoninergic structures that regulates motor function of the stomach.Π Π°Π±ΠΎΡ‚Π° посвящСна ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΡŽ сСротонинСргичСских структур, ΡƒΡΠΈΠ»ΠΈΠ²Π°ΡŽΡ‰ΠΈΡ… ΠΌΠΎΡ‚ΠΎΡ€ΠΈΠΊΡƒ ΠΆΠ΅Π»ΡƒΠ΄ΠΊΠ°.

    The magnetic ordering in the mixed valence compound beta-Na0.33V2O5

    Full text link
    The low-temperature electron spin resonance (ESR) spectra and the static magnetization data obtained for the stoichiometric single crystals of Ξ²\beta-Na0.33_{0.33}V2_2O5_5 indicate that this quasi-one-dimensional mixed valence (V4+/V5+) compound demonstrates at TN=22T_N=22 K the phase transition into the canted antiferromagnetically ordered state. The spontaneous magnetization of 3.4Γ—10βˆ’33.4\times 10^{-3} ΞΌB\mu_B per V4+^{4+} ion was found to be oriented along the two-fold bb axis of the monoclinic structure, the vector of antiferromagnetism is aligned with the aa axis and the Dzyaloshinsky vector is parallel to the cc-axis. The experimental data were successfully described in the frame of the macroscopic spin dynamics and the following values for the macroscopic parameters of the spin system were obtained: the Dzyaloshinsky field HD=6H_D=6 kOe, the energy gaps of two branches of the spin wave spectrum Ξ”1=48\Delta_1=48 GHz and Ξ”2=24\Delta_2=24 GHz.Comment: 5 pages, 6 figure

    Background: Alcohol dependence is often combined with affective disorders, in particular, depressive disorder (DD), which worsens adversely affects the prognosis of the course of both diseases and their outcomes. For the treatment of DD, drugs from the group of selective serotonin reuptake inhibitors, whose representative is fluvoxamine, are used. Fluvoxamine therapy is often associated with a risk of development is shown to be ineffective, and a part of patients develop dose-dependent adverse drug reactions (ADR) and pharmacoresistance.Objective: To study the effects of CYPD6 isoenzyme activity on the efficacy and safety of fluvoxamine therapy in patients with depressive disorders, comorbid with alcoholism.Methods: The study was conducted on 117 Russian patients with DD, alcohol-dependent comorbid. For the purpose of correction of depressive disorders within the framework of cyclothymia, fluvoxamine (Fevarin) was administered to patients at a dosage of 50βˆ’150 mg/day. Genotyping was carried out by the method of polymerase chain reaction in Real-time mode with allele-specific hybridization. Efficacy and safety were assessed using validated psychometric scales and an assessment of the severity of ADR. To evaluate the activity of CYP2D6, the method of high performance liquid chromatography with mass spectrometry was used to measure the urinary content of the endogenous substrate of this isoenzyme and its metabolite, the ratio of 6-hydroxy-1,2,3,4-tetrahydro-beta-carboline.Results: By the 9th day of the study, the severity of depressive symptoms on the HAMD scale was statistically significantly different in patients with different genotypes: (GG) 7.0 [6.0; 8.0], (GA) 4.0 [3.0; 5.0] (p0.001); safety indicator, estimated on a UKU scale: 3.0 [2.0; 4.0], (GA) 4.0 [4.0; 4.2] (p0.001). The presence of differences persisted on the 16th day: (GG) 5.0 [3.0; 6.0], (GA) 1.5 [1.0; 3.0] (p0.001); safety indicator, estimated on a UKU scale: (GG) 9.0 [9.0; 10.0], (GA) 6.0 [6.0; 7.0] (p0.001). The calculation of the correlation coefficients between the difference in the number of scores on psychometric scales and the metabolic ratio showed a statistically significant inverse correlation of the average power degree between the efficiency index estimated by the HAMD scale (r=-0.467, p0.05). There was no connection with the difference on the UKU scale (r=0.173, p0.05).Conclusion: In a study of a group of 117 patients with DD, comorbid with alcohol dependence, the effect of CYP2D6 activity, estimated by the ratio of the endogenous substrate concentrations of pinolin and its metabolite 6-hydroxy-1,2,3,4-tetrahydro-beta-carboline, on the efficacy of fluvoxamine therapy. This effect was also shown using the results of genotyping. The results of genotyping also showed the existence of a difference in the safety index in patients with different genotypes from the polymorphic marker CYP2D6 1846GA.ОбоснованиС.

    Theory of the first-order isostructural valence phase transitions in mixed valence compounds YbIn_{x}Ag_{1-x}Cu_{4}

    Full text link
    For describing the first-order isostructural valence phase transition in mixed valence compounds we develop a new approach based on the lattice Anderson model. We take into account the Coulomb interaction between localized f and conduction band electrons and two mechanisms of electron-lattice coupling. One is related to the volume dependence of the hybridization. The other is related to local deformations produced by f- shell size fluctuations accompanying valence fluctuations. The large f -state degeneracy allows us to use the 1/N expansion method. Within the model we develop a mean-field theory for the first-order valence phase transition in YbInCu_{4}. It is shown that the Coulomb interaction enhances the exchange interaction between f and conduction band electron spins and is the driving force of the phase transition. A comparison between the theoretical calculations and experimental measurements of the valence change, susceptibility, specific heat, entropy, elastic constants and volume change in YbInCu_{4} and YbAgCu_{4} are presented, and a good quantitative agreement is found. On the basis of the model we describe the evolution from the first-order valence phase transition to the continuous transition into the heavy-fermion ground state in the series of compounds YbIn_{1-x}Ag_{x}Cu_{4}. The effect of pressure on physical properties of YbInCu_{4} is studied and the H-T phase diagram is found.Comment: 17 pages RevTeX, 9 Postscript figures, to be submitted to Phys.Rev.

    Fractal iso-contours of passive scalar in smooth random flows

    We consider a passive scalar field under the action of pumping, diffusion and advection by a smooth flow with a Lagrangian chaos. We present theoretical arguments showing that scalar statistics is not conformal invariant and formulate new effective semi-analytic algorithm to model the scalar turbulence. We then carry massive numerics of passive scalar turbulence with the focus on the statistics of nodal lines. The distribution of contours over sizes and perimeters is shown to depend neither on the flow realization nor on the resolution (diffusion) scale rdr_d for scales exceeding rdr_d. The scalar isolines are found fractal/smooth at the scales larger/smaller than the pumping scale LL. We characterize the statistics of bending of a long isoline by the driving function of the L\"owner map, show that it behaves like diffusion with the diffusivity independent of resolution yet, most surprisingly, dependent on the velocity realization and the time of scalar evolution

    Large enhancement of deuteron polarization with frequency modulated microwaves

    We report a large enhancement of 1.7 in deuteron polarization up to values of 0.6 due to frequency modulation of the polarizing microwaves in a two liters polarized target using the method of dynamic nuclear polarization. This target was used during a deep inelastic polarized muon-deuteron scattering experiment at CERN. Measurements of the electron paramagnetic resonance absorption spectra show that frequency modulation gives rise to additional microwave absorption in the spectral wings. Although these results are not understood theoretically, they may provide a useful testing ground for the deeper understanding of dynamic nuclear polarization.Comment: 10 pages, including the figures coming in uuencoded compressed tar files in poltar.uu, which also brings cernart.sty and crna12.sty files neede
