Morphological and functional peculiarities of placentas from pregnant women undergoing distant and stationary CTG-monitoring

Objectives: То investigate morphological and functional peculiarities of placentas from pregnant women undergoing distant and stationary CTG monitoring. Methods: 73 placentas were investigated. The main group consists of 38 placentas from patients who were monitored distantly (home monitoring). Control group consists of 35 placentas from women who were monitored stationary (in hospital). Morphological investigation includes macroscopic evaluation, organometry (shape, size, mass), histological assessment and stereomorphometry. Results: The relationship between compensated and subcompensated forms of placental insufficiency was the same in both groups in spite of heterogeneity in morphological subsivales. Conclusions: The methods of distant and stationary CTG evaluation demonstrated the same diagnostics capabilities, which has been confirmed by the same relationship between compensated and subcompensated forms of placental insufficiency.Цели: Изучить морфофункциональные особенности последов беременных, подвергавшихся дистанционному и стационарному КТГ мониторингу. Материалы и методы: В ходе проведённого исследования были изучены морфофункциональные особенности 73 последов. Морфологическое исследование последов включало их макроскопическое описание и органометрию (форма, размер, масса), гистологическое изучение срезов, стереоморфометрию. Результаты: При сравнительной оценке морфофункциональных особенностей последов был сделан вывод о том, что несмотря на неоднородность морфологического субстрата исследуемых последов, соотношение компенсированной и субкомпенсированной форм ПН было одинаковым. Выводы: Методики дистанционного и стационарного КТГ мониторинга имеют одинаковую диагностическую ценность, что подтверждается одинаковым соотношением компенсированной и субкомпенсированной форм ПН в исследуемых группах, а так же отсутствием декомпенсированных форм ПН

Clinical and anamnestic and biological candidates for participation in the mechanisms of genital prolapse formation in women

Introduction. The article presents an overview of the results of modern evidence-based scientific research on the mechanisms of formation of genital prolapse as one of the fundamental causes of pelvic floor muscle insufficiency in women. A systematic analysis of the current literature data on the involvement of clinical, anamnestic and pathogenetic motives in the development of pelvic organ prolapse in women was carried out. Objective: to expand the understanding of the role of anamnestic and biological factors in the pathogenesis of genital prolapse in womenЦель исследования: расширить представление о роли анамнестических и биологических факторов в патогенезе пролапса гениталий у женщи

4MOST: Project overview and information for the First Call for Proposals

We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Visible and Infrared Survey Telescope for Astronomy (VISTA) at Paranal. Its key specifications are: a large field of view (FoV) of 4.2 square degrees and a high multiplex capability, with 1624 fibres feeding two low-resolution spectrographs ($R = \lambda/\Delta\lambda \sim 6500$), and 812 fibres transferring light to the high-resolution spectrograph ($R \sim 20\,000$). After a description of the instrument and its expected performance, a short overview is given of its operational scheme and planned 4MOST Consortium science; these aspects are covered in more detail in other articles in this edition of The Messenger. Finally, the processes, schedules, and policies concerning the selection of ESO Community Surveys are presented, commencing with a singular opportunity to submit Letters of Intent for Public Surveys during the first five years of 4MOST operations

Resonant transformation of the electric-dipole field into a circularly polarized field by means of a small dielectric sphere with the surface conductance along helical-type lines

Resonant transformers of the spatial and polarization structures of electromagnetic waves are known that employ semitransparent surfaces with anisotropic conductance [1, 2]. Here, we consider the problem of excitation of a dielectric sphere with the electric dipole located at its center and directed along the zaxis (Fig. 1)
