В последние годы одной из основных причин зрительных расстройств у лиц молодого возраста являются аномалии рефракции, среди которых в 80 % случаев доминирует близорукость. По прогнозам к 2050-му г. – до 5 млрд. человек, что влечет за собой значительные клинические и экономические последствия. В связи с широким распространением близорукости среди детей и подростков, возможностью её прогрессирования и возникновения осложнений, нередко приводящих к инвалидности по зрению, изучение этого заболевания представляет особую актуальность.
Viral hepatitis C (HCV) is one of the most important problems of modern medicine. According to WHO statistics, there are between 500 and 700 million HCV carriers worldwide. The aim of the study was to study the clinical and immunological features of the course of chronic viral hepatitis C, depending on the genotype of the virus, and to assess the diagnostic and prognostic value of immunological disorders. The clinical and laboratory features of the course of chronic viral hepatitis C depending on the genotype of the virus, the immunological features of the course of chronic viral hepatitis C depending on the genotype of the virus were studied, the diagnostic and prognostic value of immunological indicators as objective criteria for assessing the severity of the disease and the prognosis of the disease was determined. We examined 83 patients with chronic viral hepatitis, 35-50 years old with chronic viral hepatitis C, and 20 practically healthy individuals of the same age and gender.
The flow model of the crushing and crushing equipment is important because it allows the stone material to slide down through the crushing chamber. The crushing or crushing characteristics were achieved by testing the rock based on spring compression during crushing under controlled conditions. The input data (CSS) includes parameters such as speed, stroke, camera geometry, distribution of transmission values and mechanical properties of the material. The performance of a traditional cone crusher, which shows the performance for ore of various products. The nominal design of the conical crushing and crushing equipment is made. At this stage, it is possible to calculate a set of nominal parameters characterizing the chopper chamber. The nominal stroke and layer thickness are determined at each point of the chamber cross section. The same material was used in modeling and field tests. After each compression test, the material was screened. Distribution of the sizes received at each check. A selection function with two variables adapted to experimental data. b) functional representation in 3D. Normalized crushing of the porphyry material under study. b) the crushing properties of quartz and porphyrite were compared.
Учитывая высокую распространенность ВИЧ/СПИДав мире, возникает необходимость изучения психологическихособенностей данной группы пациентов с целью оптимизации основных направлений работы с этой категорией больных.
The issue of negative cases in the oral cavity of chemical industry workers remains relevant. It is proved that the high prevalence of non-carious lesions of the teeth, the oral mucosa is associated with such production processes as oil and gas extraction, metallurgy, chemical production, baking bread and confectionery. Prevention and rehabilitation of dental diseases helps to preserve the ability to work of a significant part of the country's population - workers of industrial enterprises, especially since a number of studies reliably reveal the role of teeth and surrounding tissues in the general state of the body.
