Hormonal status at patients with Klinefelter's syndrome after allotransplantation of testicle on arterial-venosus pedicle

This work is devoted to treatment of Klinefelter's syndrome by methode of allotransplantation of testicle on arterial-venosus pedicle. We examined hormonal status before and after operation. We observed our patients during 30 years. Changes of hormonal status showed good results of treatment of Klinefelter's syndrome by operatives methods.Целью данной работы являлось изучение влияния аллотрансплантации яичка на артерио-венозной ножке на гормональный профиль больных с синдромом Клайнфельтера. Исследовался гормональный статус до и после оперативного вмешательства у группы пациентов в течении 30 лет. Полученные данные позволяют говорить о необходимости применения оперативных методов лечения у больных с синдромом Клайнфельтера в виду стабилизации гормонального статуса у таких больных

The structures of dimeric stereoisomeric tartrates of iron(III) as determined by molecular mechanics calculations

The stereospecific formation of iron(III) complexes with d- and dl-taric acidsdH4L, dlH4L respectively) is discussed. Molecular mechanics calculations (mind program, model of Dashevsky-Plyamovatyi) are applied to modelling of dimeric tartrate Fe2(d-L)2 2- and Fe2(d-L)(l-L)2-(II) structures. Stereospecific formation is explained by lesser values of energy of rigid iron(III) octahedral coordination in (I). © 1995

Experimental investigation of high-energy photon splitting in atomic fields

The new data analysis of the experiment, where the photon splitting in the atomic fields has been observed for the first time, is presented. This experiment was performed at the tagged photon beam of the ROKK-1M facility at the VEPP-4M collider. In the energy region of 120-450 MeV, the statistics of $1.6\cdot 10^9$ photons incident on the BGO target was collected. About 400 candidates to the photon splitting events were reconstructed. Within the attained experimental accuracy, the experimental results are consistent with the cross section calculated exactly in an atomic field. The predictions obtained in the Born approximation significantly differ from the experimental results.Comment: 11 pages, 6 figures, LaTe

Composition, stability, and paramagnetic birefringence of d- and dl-terbium(III) tartrates

The formation of d- and dl-terbium(III) tartrates was studied by pH-metry and paramagnetic birefringence in combination with mathematical simulation. The paramagnetic birefringence constants were calculated. Paramagnetic anisotropy of terbium(III) in monotartrate and in binuclear species was estimated. © 1997 MAEe cyrillic signK Hayκa/Interperiodica Publishing

Measurement of J/ψ→γηcJ/\psi\to\gamma\eta_{\rm c} decay rate and ηc\eta_{\rm c} parameters at KEDR

Using the inclusive photon spectrum based on a data sample collected at the $J/\psi$ peak with the KEDR detector at the VEPP-4M $e^+e^-$ collider, we measured the rate of the radiative decay $J/\psi\to\gamma\eta_{\rm c}$ as well as $\eta_{\rm c}$ mass and width. Taking into account an asymmetric photon lineshape we obtained $\Gamma^0_{\gamma\eta_{\rm c}}=2.98\pm0.18 \phantom{|}^{+0.15}_{-0.33}$ keV, $M_{\eta_{\rm c}} = 2983.5 \pm 1.4 \phantom{|}^{+1.6}_{-3.6}$ MeV/$c^2$, $\Gamma_{\eta_{\rm c}} = 27.2 \pm 3.1 \phantom{|}^{+5.4}_{-2.6}$ MeV.Comment: 6 pages, 3 figure

Measurement of J/psi to eta_c gamma at KEDR

We present a study of the inclusive photon spectra from 5.9 million J/psi decays collected with the KEDR detector at the VEPP-4M e+e- collider. We measure the branching fraction of radiative decay J/psi to eta_c gamma, eta_c width and mass. Our preliminary results are: M(eta_c) = 2979.4+-1.5+-1.9 MeV, G(eta_c) = 27.8+-5.1+-3.3 MeV, B(J/psi to eta_c gamma) = (2.34+-0.15+-0.40)%.Comment: To be published in Proceedings of the PhiPsi09, Oct. 13-16, 2009, Beijing, Chin

Measurement of B(J/psi->eta_c gamma) at KEDR

We present a study of the inclusive photon spectrum from 6.3 million J/psi decays collected with the KEDR detector at the VEPP-4M e+e- collider. We measure the branching fraction of the radiative decay J/psi -> eta_c gamma, eta_c width and mass. Taking into account an asymmetric photon line shape we obtain: M(eta_c) = (2978.1 +- 1.4 +- 2.0) MeV/c^2, Gamma(eta_c) = (43.5 +- 5.4 +- 15.8) MeV, B(J/psi->eta_c gamma) = (2.59 +- 0.16 +- 0.31)%$.Comment: 6 pages, 1 figure.
