Optical coherence tomography angiography as an indicator of the efficacy of treatment for choroidal neovascularization
Background: Choroidal neovascularization (CNV) occurs in as much as 11.3% of patients with pathological myopia, and is a major cause of visual disability associated with irreversible loss of central vision. The advent of optical coherence tomography angiography (OCTA) has opened up new opportunities for objective documentation and real-time qualitative and quantitative evaluation of CNV in the course of therapy.
Purpose: To assess the efficacy of anti-vascular epithelium growth factor (VEGF) therapy with ranibizumab in CNV associated with pathological myopia using OCTA.
Material and Methods: Thirty seven anti-VEGF-treatment naive patients (37 eyes) with myopic CNV were involved in the study. All study participants received an intravitreal ranibizumab injection (in accordance with the manufacturer’s recommendations) followed by as needed (PRN) retreatment.
Results: Complete subretinal fluid resorption with adherence of the neurosensory retina was observed in all the 37 eyes; the mean number of intravitreal ranibizumab injections required was 4.56 ± 0.1. Over the 18-month follow up period, best-corrected visual acuity (BCVA) improved from 0.12 ± 0.03 to 0.42 ± 0.04 in 27 eyes (72.97%). OCTA patterns of CNV activity tended to fade, with the characteristic presence of isolated long filamentous vessels having a “dead tree” appearance.
Conclusion: Application of OCTA, an information-rich modality, in pathological myopia, facilitates a personalized approach to determining the need for anti-VEGF therapy and selecting the mode of administration of anti-VEGF agents based on the CNV activity
Juchi Khan Mausoleum: realities, legends and rituals
Lore and folk legends designate the burial of Jochi Khan, the eldest son of Genghis Khan, in the eponymous mausoleum in Ulytau, Kazakhstan. The mausoleum was built according to Islamic architecture of the 14th-15th centuries. A.Kh. Margulan, the author of archeological excavations, relying mostly on the folk legends designated the mausoleum’s burial to Jochi Khan. Radiocarbon dating of mausoleum determines two stages of its construction throughout the 14th century and the burial box age later than the death of Jochi Khan in 1225. New evidence from the mausoleum architecture and artifacts suggests that Jochi's burial is not in the mausoleum but a secret place prescribed by the Chinggisid canon. The assembly of Islamic and pre-Islamic traditions and the camel skull found in the burial indicates that the burial was made for a person of Islamic faith from the Golden Horde. Whereas the mausoleum was named in the honor of Jochi Khan
ИЗУЧЕНИЕ ПОКАЗАТЕЛЕЙ БЕЗОПАСНОСТИ ЗЕРНОВОГО ПРОДУКТА «ЗЛАКОВЫЙ БАТОНЧИК»
The study of food products is the most important method for creating proves of their food safety based on generally accepted scientific ideas and current international and national legal norms of food safety. At the stage of laboratory research it is possible to objectively prove the efficiency and safety of new types of food products while their consumption according to certain health indications among the relevant group of people, including staff working in hazardous industrial environment. In the Russian Federation the procedure for assessing the safety and running the laboratory tests of food products are regulated by the Federal Laws on the Quality and Safety of Food Products, regulations on provision of public catering services, methodological recommendations for assessing the risk to public health in case of exposure to microbial factors contained in food products, as well as technical regulations of the Customs Union on food safety. The authors have developed regulatory and technical documentation for the cereal product “Cereal bar” and presented data on its safety when consumed. Conclusions about the product are made on the basis of a study of its chronic toxicity. It has been established that the ingredients composition of the cereal bar, included in the diet of laboratory animals, provided a positive effect on their body condition, weight gain and did not cause abnormal changes in the volume of internal organs and the development of pathologies that could indicate a side effect of the product. During study of the hematological and biochemical parameters, no significant differences were found between the data of the control group and experimental group of the animals. The conducted studies of the cereal product “Cereal bar” confirm the absence of a potential risk of developing chronic toxicity in case of introduction of the cereal bar to the animals’ diets and its consumption over a long period of time.Исследование пищевых продуктов является важнейшим инструментом построения доказательной базы их безопасности исходя из общепринятых научных представлений и действующих международных и национальных правовых норм. На этапе лабораторных исследований можно объективно доказать эффективность и безопасность новых видов пищевой продукции при применении по определенным показаниям у соответствующего контингента лиц, в том числе работающих во вредных производственных условиях.

Результаты геодезических измерений баланса массы некоторых ледников Заилийского Алатау
SummaryThe current state and mass balance of some glaciers of the Trans-Ili Alatau (Zailiyskiy Alatau, Tien Shan, Kazakhstan) is estimated in the paper. The remote sensing data (images of the Pléiades satellites) and detailed field geodetic measurements (differential global positioning system with the South G6 instrument)were used for the analysis. The field works were carried out in August-September 2021on the northern slope of the Zailiyskiy Alatau ridge. A digital relief model had been built for the analysis as well. Negative trends in the area of the studied glaciers have been revealed, which generally correspond to the average rate of degradation of the glaciation of the Trans-Ili Alatau from 1955 to the present. A comparison of glaciological (contact, i.e., obtained as a result of measurements made on the glacier) and geodetic (resulted from analysis of remote sensing data) methods for estimating the annual mass balance of the Central Tuyuksu glacier for the period 2016-2021 showed that the final values calculated by these two methods are very close in values. For example, the sum of annual balances calculated by the glaciological method for this period was -2.9 m w.e., or -0.58 a-1 m w.e. per a year, while the balance calculated by the geodetic method for the same period was - 0.63 a-1 m w.e. Thus, the results of comparison of the above methods of the glacier mass-balance investigation confirm that the geodetic one based on satellite measurements and the ground surveys using the South G6 instrument is in a good agreement with results of glaciological methods of measurements and calculations.Деградация оледенения вызывает изменения в горных экосистемах, оказывая непосредственное влияние на жизнедеятельность людей, вызывает изменения в гидрологическом режиме, биогеохимии рек и гляциальных озёр, влияя на качество и доступность водных ресурсов.

The Origins and Spread of Domestic Horses from the Western Eurasian Steppes
Domestication of horses fundamentally transformed long-range mobility and warfare1. However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling2–4 at Botai, Central Asia around 3500 bc3. Other longstanding candidate regions for horse domestication, such as Iberia5 and Anatolia6, have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 bc, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association7 between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 bc8,9 driving the spread of Indo-European languages10. This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium bc Sintashta culture11,12. © 2021, The Author(s).We thank all members of the AGES group at CAGT.
