Spanish flu at the beginning of the 20th century: scope, mortality, treatment methods

In the literature on the history of medicine and epidemiology, the problem of the emergence and development of the Spanish flu has clearly received insufficient attention. Almost all the literature is devoted to the social consequences of this pandemic. Researchers have repeatedly turned to the history of the deadliest influenza pandemic of the twentieth century, but special interest in it today is associated with the emergence of a new COVID pandemic. The purpose of the study is to briefly summarize the data on the origin of the Spanish flu and clarify its scale in 1918–1920. The authors analyze the treatment methods of that time, and also try to trace modern views on the origin and genesis of this influenza strain. The authors also tried to explain the causes of high mortality among people of military age, the rate of spread and infection, to identify the features of the course of this disease in Russia. It is concluded that the causative agent of the Spanish flu became the progenitors of many modern influenza strains that caused the epidemics of the XX and XXI centuriesВ литературе по истории медицины и эпидемиологии проблеме возникновения и развития испанского гриппа уделялось явно недостаточное внимание. Практически вся литература посвящена социальным последствиям этой пандемии. Исследователи не раз обращались к истории самой смертоносной гриппозной пандемии XX века, но особый интерес к нему сегодня связан с появлением новой пандемии COVID, поскольку штаммы этих заболеваний во многом аналогичны. Цель исследования состоит в кратком обобщении данных о происхождении испанского гриппа и уточнении его масштабов в 1918–1920 гг. Авторы анализируют методы лечения того времени, а также пытаются проследить современные взгляды на происхождение и генез этого гриппозного штамма. Авторы также попытались объяснить причины высокой смертности среди лиц призывного возраста, скорость распространения и инфицирования, выявить особенности протекания этого заболевания в России. Сделан вывод, что возбудитель испанского гриппа стал родоначальников многих современных гриппозных штаммов, вызвавших эпидемии XX и XXI столетий

NEW CULTIVAR OF SOFT WINTER WHEAT ‘BEREZIT’

New cultivar of soft winter wheat ‘Berezit’ has been described in the article. The cultivar is a middle-late maturing one with a set of unique characteristics. It possesses a complex immunity to leaf-stem diseases widely spread in the region and doesn’t need any fungicide treatment during vegetation period. The variety possesses higher salt tolerance than a standard one ‘Stepnaya 7’ well-known in the area

Morphological and endoscopic diagnostic criteria of serrated adenomas of the colon

The aim of review. To generalize literature data on endoscopic and morphological diagnostics of serrated adenomas of the colon. Key points. In 2010 a new variant of histological classification of colonic tumors have been accepted by WHO, according to which serrated neoplasms were defined as separate group of preneoplastic changes, along with colonic adenomas. At the present time hyperplastic polyps and other serrated neoplasms are considered to be precursor lesions for 15 to 20% of sporadic or asymptomatic colorectal cancers located mainly in proximal colon, that progress by specific serrated adenoma-related pathway. Diagnostics of such lesions both on microscopic and macroscopical levels is associated with significant difficulties due to absence of the uniform nomenclature, definite morphological features and endoscopic semiotics. Conclusion. Definition of main morphological and endoscopic diagnostic criteria of all types of serrated adenomas will provide successful diagnostics along with differentiation with other epithelial colonic lesions that is required for proper choice of management approach

Publisher Copyright: © 2023 The Author(s)We analysed the parsec-scale linear polarization properties of 436 active galactic nuclei (AGNs) based on 15 GHz polarimetric Very Long Baseline Array observations. We present polarization and total intensity images averaged over at least five epochs since 1996 January 19 through 2019 August 4. Stacking improves the image sensitivity down to ∼30 μJy beam−1 and effectively fills out the jet cross-section both in total intensity and linear polarization. It delineates the long-term persistent magnetic field configuration and its regularity by restoring spatial distributions of the electric vector position angle (EVPA) and fractional polarization, respectively. On average, about 10 yr of stacking period is needed to reveal the stable and most-complete polarization distribution of a source. We find that the degree of polarization significantly increases down and across the jet towards its edges, typically manifesting U or W-shaped transverse profiles, suggesting a presence of a large-scale helical magnetic field associated with the outflow. In some AGN jets, mainly BL Lacs, we detect quasi-constant fractional polarization profiles across the jet, accompanied by EVPAs that closely follow the outflow. BL Lacs show higher fractional polarization values in their cores and jets than those in quasars up to hectoparsec de-projected scales, while on larger scales, they become comparable. High-synchrotron-peaked BL Lac jets are found to be less polarized than intermediate and low-synchrotron-peaked BL Lacs. The spatial distribution of the EVPAs in BL Lacs tend to align with the local jet direction, while quasars show an excess of orthogonal polarization orientation.Peer reviewe

MOJAVE XXI. Decade-long linear polarization variability in AGN jets at parsec scales

Using stacking of images obtained at different epochs, we studied the variability properties of linear polarization of active galactic nucleus (AGN) jets on parsec-scales. Our sample is drawn from the MOJAVE programme, and consists of 436 AGNs manifesting core-jet morphology and having at least five VLBA observing epochs at 15 GHz from January 1996 through August 2019, with some additional archival VLBA data reduced by us. We employed a stacking procedure and constructed maps of (i) standard deviation of fractional polarization and electric vector position angle (EVPA) over epochs as the measure of variability and (ii) median polarization degree to quantify typical values in time. The distributions of these values along and across the jet were analysed for the whole sample for the first time. We found that core EVPA variability is typically higher than that of the jet, presumably due to component blending and outflow bends in the core. The BL Lacertae object cores have lower EVPA variability, compared to that of quasars, possibly due to lower Faraday rotation measure, suggesting a stronger ordered magnetic field component. The EVPA becomes more stable down the jet. Most of the sources showing this trend have a time coverage of more than 12 years and at least 15 epochs. The possible cause could be the increase of stability in the magnetic field direction, reflecting an increase in the fraction of the magnetic field that is ordered. There are no significant optical-class-dependent or spectral-class-dependent relations in the EVPA variability properties in AGN jets.Comment: 15 pages, 11 figures, 5 tables; accepted by MNRAS; full electronic tables are available as ancillary file
