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)

Use of Polyguanidine-Derivatives-Based Biocides for Microbial Growth Inhibition and for the Development of A Novel Polyethylene-Based Composite Material Resistant to the Formation of Multispecies Microbial Biofilms

This study aimed to investigate the dependence of the biocidal activity of polyguanidine (co)polymers on their structure during the formation of biofilms by active PE-degrading cultures of model microorganisms. The Bc-2 copolymer of methacryloyl guanidine hydrochloride (MGHC) and diallyldimethylammonium chloride (DADMAC), which suppressed both the formation of biofilms and the growth of planktonic cultures, exhibited the highest activity. When PE was exposed in tropical soil, the composition of the microbial community on the PE surface differed significantly from that of the community in the surrounding soil. In particular, the proportion of Actinobacteria increased from 7% to 29%, while the proportion of Bacteroidetes decreased from 38% to 8%.
