The transcendent equations, defining the energy spectra of the systems are obtained. The dependence of the energy levels from the wall sizes is found.Comment: 8 pages, 5 figure

Changes of the body functions during long-term hypokinesia

Prolonged hypokinesis (100-170 days) studied in 2000 rats kept in cages limiting their mobility provoked considerable changes in the gaseous and energetic metabolism: an elevation of the total gaseous metabolism and of the rate of O2 requirement by the muscles (in the late periods of hypokinesis) and a change in the intensity of tissue respiration of the liver and myocardium. There also proved to be a reduction in the level of phosphorylation and separation of oxidative phosphorylation in the myocardium, liver, and partially in the skeletal muscle. Prolonged hypokinesia led to changes in tissue metabolism: a disturbance of development of the animals, a marked delay and an increase in the weight of the organism and the muscular system, and disturbances of the mineral and protein metabolism. Prolonged hypokinesis also lead to exhaustion of the hypothalamus-hypophysis-adrenal cortex system

АNALYSIS OF THE EXPRESSION LEVEL OF T-CELL GENES AND OXIDATIVE PROCESSES IN STROKE

The level of expression of genes of transcription factors (GATA-3, TBX21, IL-2PG), and changing  of oxidative processes in ischemic stroke were studied.It was found that activation of Th2 cells (increase in the expression of transcription factor GATA-3) is observed in stroke,   and suppression of Th1 cells (a decrease in the expression of IL-2 and its receptors, as well as the TBX21 gene).  Increasing the expression of transcription factor GATA-3 in stroke patients underlies the increase in production in these patients of Th2-cytokines.    A comparative analysis of protein oxidation in blood plasma revealed an increase in the intensity of oxidative modification of proteins in stroke patients.  Investigation of glutathione content, activity of glutathione peroxidase enzymes, glutathione reductase in erythrocytes in stroke revealed a decrease in the content of glutathione and glutathione reductase and an increase in the activity of glutathione peroxidase.The findings may be useful for a better understanding of the mechanisms of stroke

Spectral properties of a short-range impurity in a quantum dot

The spectral properties of the quantum mechanical system consisting of a quantum dot with a short-range attractive impurity inside the dot are investigated in the zero-range limit. The Green function of the system is obtained in an explicit form. In the case of a spherically symmetric quantum dot, the dependence of the spectrum on the impurity position and the strength of the impurity potential is analyzed in detail. It is proven that the confinement potential of the dot can be recovered from the spectroscopy data. The consequences of the hidden symmetry breaking by the impurity are considered. The effect of the positional disorder is studied.Comment: 30 pages, 6 figures, Late

The Updated Zwicky Catalog (UZC)

The Zwicky Catalog of galaxies (ZC), with m_Zw<=15.5mag, has been the basis for the Center for Astrophysics (CfA) redshift surveys. To date, analyses of the ZC and redshift surveys based on it have relied on heterogeneous sets of galaxy coordinates and redshifts. Here we correct some of the inadequacies of previous catalogs by providing: (1) coordinates with <~2 arcsec errors for all of the Nuzc catalog galaxies, (2) homogeneously estimated redshifts for the majority (98%) of the data taken at the CfA (14,632 spectra), and (3) an estimate of the remaining "blunder" rate for both the CfA redshifts and for those compiled from the literature. For the reanalyzed CfA data we include a calibrated, uniformly determined error and an indication of the presence of emission lines in each spectrum. We provide redshifts for 7,257 galaxies in the CfA2 redshift survey not previously published; for another 5,625 CfA redshifts we list the remeasured or uniformly re-reduced value. Among our new measurements, Nmul are members of UZC "multiplets" associated with the original Zwicky catalog position in the coordinate range where the catalog is 98% complete. These multiplets provide new candidates for examination of tidal interactions among galaxies. All of the new redshifts correspond to UZC galaxies with properties recorded in the CfA redshift compilation known as ZCAT. About 1,000 of our new measurements were motivated either by inadequate signal-to-noise in the original spectrum or by an ambiguous identification of the galaxy associated with a ZCAT redshift. The redshift catalog we include here is ~96% complete to m_Zw<=15.5, and ~98% complete (12,925 galaxies out of a total of 13,150) for the RA(1950) ranges [20h--4h] and [8h--17h] and DEC(1950) range [-2.5d--50d].

Adiabatic description of nonspherical quantum dot models

Within the effective mass approximation an adiabatic description of spheroidal and dumbbell quantum dot models in the regime of strong dimensional quantization is presented using the expansion of the wave function in appropriate sets of single-parameter basis functions. The comparison is given and the peculiarities are considered for spectral and optical characteristics of the models with axially symmetric confining potentials depending on their geometric size making use of the total sets of exact and adiabatic quantum numbers in appropriate analytic approximations

МЕТОДЫ ДИАГНОСТИКИ СТОРОЖЕВОГО ЛИМФАТИЧЕСКОГО УЗЛА У БОЛЬНЫХ РАКОМ МОЛОЧНОЙ ЖЕЛЕЗЫ

Objective: to provide various methods for sentinel lymph node detection considering their advantages and disadvantages.Material and Methods. The search of the relevant articles published in Pubmed, MedLine, RINTs, etc. database was conducted. 49 publications from 1970 to 2018 were analyzed.Results. Currently, sentinel lymph node biopsy (SLN biopsy) has become a worthy alternative to traditional lymphatic surgery for early breast cancer. SLN biopsy significantly decreases the number of postoperative complications caused by lymphadenectomy and improves the quality of life of cancer patients. So far, a large number of SLN detection techniques have accumulated. Each of these techniques has its own advantages and disadvantages.Conclusion. Despite a large number of SLN detection methods, the question of the optimal technique is currently debatable. Цель исследования – представить различные методы диагностики сторожевых лимфатических узлов, рассмотрев их достоинства и недостатки.Материал и методы. Проведен поиск статей, опубликованных в базах Pubmed, MedLine, РИНЦ, РГБ за 1970–2018 гг. Из 150 проанализированных публикаций в обзор вошли 50.Результаты. В настоящее время биопсия сторожевого лимфатического узла (СЛУ) стала достойной альтернативой традиционной хирургии на лимфатических путях при раннем раке молочной железы (РМЖ). Благодаря данной методике снизилось количество послеоперационных осложнений, вызванных лимфодиссекцией, а качество жизни больных значительно возросло. С момента появления и до настоящего времени накопилось большое количество техник определения СЛУ, каждая из которых имеет свои плюсы и минусы.Заключение. Несмотря на большое количество методов детекции СЛУ, вопрос об оптимальной технике в настоящее время остается дискуссионным.
