Expression of pinopodies in women with endometry hyperplasia without atipy and fertility disorders
Non-atypical endometrial hyperplasia (EH) most often occurs against a background of
relative or absolute hyperestrogenism, responds to abnormal hormonal effects. In the
reproductive age, the presence of EH can be a factor in the development of fertility disorders.
The aim of the study was to learn the expression of pinopodes in ovulatory infertile women
with non-atypical EH on the day of the implantation window. Under observation there were
196 women of reproductive age, of which 166 had been treated for infertility, and 30
conditionally gynecologically and somatically healthy, fertile women of the control group. A
special examination of women included the determination in the endometrium by scanning
electron microscopy of pinopodes’ expression. It was found that in women with non-atypical
hyperplasia of the endometrium, areas without pinopodia were recorded in 47.59% of cases,
pinopodes of small size - in 79.52% and abundant, small, thick microvilli - in 37.95%; the
decrease in the incidence of developed pineapods in comparison with healthy prolific women
was 2.72 times, that of pinopodes of large size was 3.39 and the small number of microvilli
was 3.64, an increase in the occurrence of pinopodes of medium size 3.65, microvilli in
moderate amounts - at 3.74. The authors conclude that the characteristic feature of
endometrial pinopodes in EH is the presence of mosaicism of their shape (60.24%), size (64.46%) and the presence of numerous areas of absence of pinopodes (47.59%), which plays
a significant role in disorders fertility

Abstract
More than 50% of pregnant women after the programs of assisted reproductive technologies (ART) face the problem of recurrent miscarriage (RMC), especially in the first trimester. Significant role in the development of RMC has infectious factor and chronic inflammation in the endometrium. The aim: to reveal the peculiarities of immune response mRNA genes of the inflammatory component expression in the period of the tentative implantation window (TIW) in women with RMC in ART programs. Material and methods. The main group consisted of 240 patients with RMC in ART programs; the control group included 100 conditionally healthy fertile women. On the ground of PCR reverse transcription, the mRNA of the IL-1β, IL-2, IL-10, Foxp3, TLR9, IL-2Rα cytokine genes was examined in endometrial samples obtained with the help of biopsy on the TIW day. Results. Analysis of the transcriptional profile of the immune response genes in the endometrium on TIW day revealed that the relative level of mRNA expression of the IL-1β, IL-2, Foxp3, TLR9, IL-2Rα genes did not differ significantly in the main and control groups. Statistically significant decrease in mRNA expression of IL-10 gene was observed in women with RPL. Conclusions. A feature of mRNA expression of the inflammatory component of the immune response in TIW period in women with RMC in ART programs is a decrease in the expression level of the IL-10 gene mRNA, which may be one of the reasons for the unfavorable outcomes of the onset pregnancy.

Hadroproduction of the Chi1 and Chi2 States of Charmonium in 800 GeV/c Proton-Silicon Interactions
The cross sections for the hadroproduction of the Chi1 and Chi2 states of
charmonium in proton-silicon collisions at sqrt{s}=38.8 GeV have been measured
in Fermilab fixed target Experiment 771. The Chi states were observed via their
radiative decay to J/psi+gamma, where the photon converted to e+e- in the
material of the spectrometer. The measured values for the Chi1 and Chi2 cross
sections for x_F>0 are 263+-69(stat)+-32(syst) and 498+-143(stat)+-67(syst) nb
per nucleon respectively. The resulting sigma(Chi1}/sigma(Chi2) ratio of
0.53+-0.20(stat)+-0.07(syst), although somewhat larger than most theoretical
expectations, can be accomodated by the latest theoretical estimates.Comment: 4 pages, 4 figure
Challenges in QCD matter physics - The Compressed Baryonic Matter experiment at FAIR
Substantial experimental and theoretical efforts worldwide are devoted to
explore the phase diagram of strongly interacting matter. At LHC and top RHIC
energies, QCD matter is studied at very high temperatures and nearly vanishing
net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was
created at experiments at RHIC and LHC. The transition from the QGP back to the
hadron gas is found to be a smooth cross over. For larger net-baryon densities
and lower temperatures, it is expected that the QCD phase diagram exhibits a
rich structure, such as a first-order phase transition between hadronic and
partonic matter which terminates in a critical point, or exotic phases like
quarkyonic matter. The discovery of these landmarks would be a breakthrough in
our understanding of the strong interaction and is therefore in the focus of
various high-energy heavy-ion research programs. The Compressed Baryonic Matter
(CBM) experiment at FAIR will play a unique role in the exploration of the QCD
phase diagram in the region of high net-baryon densities, because it is
designed to run at unprecedented interaction rates. High-rate operation is the
key prerequisite for high-precision measurements of multi-differential
observables and of rare diagnostic probes which are sensitive to the dense
phase of the nuclear fireball. The goal of the CBM experiment at SIS100
(sqrt(s_NN) = 2.7 - 4.9 GeV) is to discover fundamental properties of QCD
matter: the phase structure at large baryon-chemical potentials (mu_B > 500
MeV), effects of chiral symmetry, and the equation-of-state at high density as
it is expected to occur in the core of neutron stars. In this article, we
review the motivation for and the physics programme of CBM, including
activities before the start of data taking in 2022, in the context of the
worldwide efforts to explore high-density QCD matter.Comment: 15 pages, 11 figures. Published in European Physical Journal
Экспрессия рецепторов к стероидным гормонам в эндометрии при его неатипической гиперплазии как причина нарушений женской фертильности и неудач гормонотерапии
При неатиповій гіперплазії
ендометрія (ГЕ) у жінок репродуктивного віку в 94,4 % спостерігається безпліддя, в 31,5 %
– невиношування вагітності. Метою дослідження стало оцінка стану стероїдного
рецепторного статусу ендометрія при його неатиповій гіперплазії у пацієнток з
порушеннями фертильності. Обстежено 72 жінки з ГЕ і розладами фертильності і 30
здорових жінок. Проведено визначення експресії рецепторів естрогенів-α (RE-α) і
прогестерону (RР) в ендометрії імуногістохімічним методом в день передбачуваного вікна
імплантації. Виявлено, що при неатиповій ГЕ спостерігається значуще, нерівномірне по
інтенсивності та концентрації збільшення експресії рецепторів до RE-α і RР в залозах
ендометрія, ніж в стромі, при цьому переважає підвищення експресії RР. Але у 27,78 %
жінок з неатиповою ГЕ спостерігається відсутність або сліди імунозабарвлення в залозах
ендометрія RE-α і 15,28 % – RР, в стромі – відповідно 41,67% і 45,83 %. Автори роблять
висновок, що порушення експресії RE-α і RР при неатиповій ГЕ може приводити до
порушень децидуалізації, імплантації та плацентації, а також невдач гормонотерапії.In non-atypical hyperplasia
of endometrium (GE) in women of reproductive age in 94,4% cases infertility is observed, in
31,5% - miscarriages. The aim of the study was to assess the status of the steroid receptor
expression in the endometrium with its non-atypical hyperplasia in patients with impaired fertility.
72 women with GE and fertility disorders and 30 healthy women were examined. The expression
of estrogen-α (RE-α) and progesterone (RP) receptors in the endometrium was determined by the
immunohistochemical method on the day of the implantation window. It was found that at the nonatypical ET a significant increase in the expression of receptors to RE-α and RP in the endometrial
glands is noticeably uneven in intensity and concentration, compared with the stroma, with an
increase in the expression of RP. But in 27.78% of women with non-atypical GE there is a lack or
traces of immune staining in the endometrial glands RE-α and in 15,28% - RP, in the stroma -
41,67% and 45,83% respectively. The authors conclude that the violation of the expression of RE-
α and RP in non-atypical GE can lead to violations of decidualization, implantation and
placentation, as well as failure of hormone therapy.При неатипической

бесплодие, в 31,5% - невынашивание беременности. Целью исследования стала оценка
состояния стероидного рецепторного статуса эндометрия при его неатипической
гиперплазии у пациенток с нарушениями фертильности. Обследовано 72 женщин с ГЭ и
нарушениями фертильности и 30 здоровых женщин. Проведено определение экспрессии
рецепторов эстрогенов-α (RE-α) и прогестерона (RР) в эндометрии
иммуногистохимическим методом в день предполагаемого окна имплантации. Обнаружено,
что при неатипической ГЭ наблюдается значимое, неравномерное по интенсивности и
концентрации увеличение экспрессии рецепторов к RE-α и RР в железах эндометрия по
сравнению со стромой, при этом преобладает повышение экспрессии RР. Но у 27,78%
женщин с неатипической ГЭ наблюдается отсутствие или следы иммунного окрашивания в
железах эндометрия RE-α и у 15,28% – RР, в строме – соответственно – у 41,67% и у
45,83%. Авторы делают вывод о том, что нарушение экспрессии RE-α и RР при
неатипической ГЭ может приводить к нарушениям децидуализации, имплантации и
плацентации, а также неудачам гормонотерапии
The full-length prototype of the KLOE drift chamber
The main goal of the KLOE experiment is the study of CP violation in the K mesons system, with an accuracy of 10(-4) in the measurement of Re(epsilon'/epsilon). This task imposes strong constraints on the design and operation of the drift chamber, which must reconstruct the charged decays of low momentum K-L's and K-S's with high efficiency and high resolution, full-length prototype of the chamber has been built and tested on a 50 GeV/c beam. The analysis of the large sample of data has allowed a detailed study of the time to distance relations as a function of the track parameters and of the peculiar geometry of the drift cell, The detector performance, in terms of efficiency, spatial resolutions and dE/dx resolution, is illustrated and discussed
