The role of hypoxia in the pathogenesis of congenital hyperplasia of blood vessels in the head and neck in children (literature review)
To date, scientists have found that stress plays an important role in the formation of congenital malformations. It can be caused by the influence of negative environmental factors on the pregnant woman or by her own diseases. One of the consequences of stress is hypoxia. It can be acute and chronic, and can have a negative impact both during pregnancy and during childbirth. They also distinguish local and general hypoxia. The consequences of the negative impact of oxygen deficiency on the embryo and fetus can manifest itself both in utero and after birth, leading to various kinds of congenital malformations, diseases, and sometimes fetal death, or increase the risk of sudden infant death syndrome. Hyperplasia of blood vessels, the so-called children’s hemangiomas, develops both in utero, especially with chronic fetal hypoxia, and during childbirth. It develops due to insufficient blood supply and oxygen deficiency in various parts of the body, most often in the head and neck. In an embryo under conditions of hypoxia, tachycardia develops – with an increase in heart rate and, if it is ineffective, local vasodilation occurs. Only then, under the condition of continuing hypoxia, does an increase in the number of blood vessels develop. This often leads to the formation of hyperplasia of the blood vessels, the so-called children’s hemangiomas.This pathology is quite common, especially among fair-skinned children, which makes its study, in particular the factors that cause this pathology, relevant today

Изучение дрейфа айсбергов у побережья Северной Земли весной 2018 г. с помощью спутниковой информации
The movement of icebergs in the Laptev Sea off the coast of the Severnaya Zemlya archipelago in spring of 2018 was analyzed using satellite observations in visible spectral band. As is shown in the article the data of radiometers installed on the Landsat-8 and Sentinel-2 satellites allow monitoring of iceberg drifting in spring period in the above Arctic region. Thus, in March-April 2018, the total amount of icebergs detected near the archipelago was 4917. 4161 icebergs were in the landfast ice, 722 ones were drifting with the ice fields, and the other 32 were aground in ice fields. The average length of the icebergs was equal to 88 m; the largest of the recognized icebergs was located in the landfast ice near the ice shelf of the Matusevich fjord and it was 1240 m in length. The maximum speed of drift of the icebergs, as determined by the satellite data, was equal to 29.5 km/day. This was estimated for the situation when the speed of the near-water (surface) wind reached 20 m/s and larger. The purpose of the work was to study drifting of icebergs in order to define more exactly dynamics of the iceberg movement in this poorly known area of the Arctic. It is found that in a case of the consolidated ice cover the drift speed of ice fields with the icebergs involved depends on the driving wind force and direction. According to mean speeds of movement all icebergs were separated into three groups: the icebergs of the coastal zone with velocities smaller 1 km/day; the icebergs of the transition zone at speeds of 1.3 to 1.6 km/day; and the icebergs of the transit zone with speeds larger 2 km/day. The characteristics of the iceberg drifts obtained on the basis of daily satellite monitoring can be used in regional iceberg drift models to ensure safe economic activity on the Arctic shelf. Also, they can find application in engineering calculations in the design of infrastructure facilities on the shelf of the Arctic seas.Обсуждаются результаты спутникового мониторинга айсбергов, находившихся в сплочённом ледяном покрове у побережья Северной Земли в марте-апреле 2018 г. Показано, что айсберги вместе с ледяными полями перемещались на северо-запад из моря Лаптевых в Арктический бассейн, причём скорость перемещения зависела от скорости приводного ветра. Приведены траектории 50 айсбергов по наблюдениям за 1-3,5 месяцев
Оценка объёма айсбергового стока с выводных ледников Северной Земли за 2014–2019 гг.
Volume of icebergs calved from the output glaciers located on the Northern Land during 2014–2019 was estimated using the satellite information. High-resolution satellite data were obtained in the visible spectral range from the non-commercial satellites Sentinel‑2 (spatial resolution 10 m) and Landsat‑8 (spatial resolution 15 m). Data collection was carried out under conditions when the natural illumination in the Arctic was sufficient (March–September) to make pictures in the visible spectral range. About 100 satellite images were analyzed for each year of the above period. The technique used for the iceberg detection is based on statistical criteria for finding the gradient zones in the analysis of two-dimensional fields of satellite images. The generation of the iceberg from a particular glacier was verified by using a form template of the detected iceberg taking into consideration the following parameters of the object: the geometrical shape, dimensions, specific features of «picture» of the ice surface (presence and orientation of cracks, peaks, and lakelets of melt water). The iceberg height was determined by its shadow on the image. The calculated total annual volume of icebergs from the outlet glaciers was estimated 1.52–1.9 km3. According to satellite data, the annual area reduction of the Northern Land outlet glaciers averaged 13 km2. The greatest contribution is made by 12 outlet glaciers located on the Komsomolets and the October Revolution islands. Of these, six are from the Academy of Sciences ice dome, four – the glaciers of the Matusevich Fjord, the Vavilov Glacier and the Rusanov dome glacier № 12. Icebergs of maximum height (30–40 m) are produced by glaciers of the North-Eastern slope of the Academy of Sciences ice dome and glacier № 12 of the Rusanov dome. In general, according to satellite data of recent years, generation of icebergs from the outlet glaciers of the Northern Land shows a steady growth trend.По спутниковым данным видимого спектрального диапазона оценена продуктивность выводных ледников Северной Земли как источников айсбергов в период 2014–2019 гг. Рассчитанный ежегодный суммарный айсберговый сток с выводных ледников составил 1,52–1,9 км3. Наибольший вклад в айсберговый сток вносят выводные ледники ледникового купола Академии наук и шельфовый ледник Матусевича. Согласно спутниковым данным последних лет, айсберговый сток выводных ледников Северной Земли имеет устойчивую тенденцию к росту
Clinical significance of sensitization to house dust mite allergens using flow cytometry-based basophil activation test
Respiratory allergy takes a significant place among allergic diseases. Similar clinical manifestations occur in sensitized patients in response to various airborne allergens. Accordingly, the allergen testing by means of in vivo and in vitro techniques is necessary to identify a causally significant allergen. The main laboratory assay to estimate sensitization to the airborne allergens is based on detection of specific immunoglobulin E (sIgE). However, clinical manifestations cannot be always confirmed by this test. The aim of this work was to evaluate the potential of basophil activation test (BAT) using flow cytometry, in order to confirm sensitization to house dust mite allergens. The BAT was carried out with allergens from Dermatofagoides in 34 volunteers, 130 patients were examined at the Russian Centre of Emergency and Radiation Medicine (33 people with household and 97 people with polysensitization), and 10 patients with allergy to house dust mites confirmed by skin testing. The sensitization was assessed using two laboratory kits (Allergenicity and BD FastImmune). The total IgE and sIgE to house dust mites, as well as concentrations of eosinophilic cationic protein, were determined. Specificity of the BAT with Allergenicity kit for the house dust mites was 94%. The sensitivity was 88% in the patients with household sensitization, thus being comparable with skin testing results available from the literature. An absolute correlation was found between positive results of skin testing and the BAT. In patients with household sensitization, sIgE levels > 0.35 UA/mL were detected in 39% of cases. A positive correlation was shown between the indices of basophil activation in response to testing allergens, and total immunoglobulin E and sIgE concentrations. High degree of correlation was found between the results of Dermatofagoides sensitization testing with both BAT kits. It was shown that the use of H1 histamine receptor blockers had no effect on BAT results. A decrease in sensitivity assay for airborne allergens was revealed upon therapy with glucocorticosteroids. Due to the proven clinical significance of the basophil activation test for diagnosing sensitization to inhaled allergens, one may require to supplement the range of approved assays in Russian Clinical Guidelines with BAT testing to prove sensitization in patients with allergic rhinitis and bronchial asthma, thus contributing to better diagnosis of causally significant allergens and, accordingly, administration of proper therapy
