Electron microscopic immunocytochemistry provides an important tool to determine the ultrastructural distribution of various molecules in both normal and pathologic tissues. However, the specific immunostaining may be obscured by artifactual immunoreaction product, misleading the investigator. Previous observations show that shortening the incubation period with the primary antibody from the generally used 12-24 hours to 1 hour substantially reduces the artifactual immunostaining. We now extend this finding by the demonstration of artifact-free ultrastructural localization of the Ca2/calmodulindependent cyclic nucleotide phosphodiesterase (CaM-dependent PDE) immunoreactivity in brain.Anesthetized rats were perfused transcardially with phosphate-buffered saline followed by a fixative containing paraformaldehyde (4%) and glutaraldehyde (0.25%) in PBS. The brains were removed, and 40μm sections were cut with a vibratome. The sections were processed for immunocytochemistry as described by Ludvig et al. Both non-immune rabbit serum and specific CaM-dependent PDE antibodies were used. In both experiments incubations were at one hour and overnight. The immunostained sections were processed for electron microscopic examination.

High Power Radiation

The Smith-Purcell radiation of a charged particle moving in a periodic structure is analysed theoretically. The considered structure consists of two planar diffraction gratings with different periods which are formed by parallel conducting wires. The analytical expression for the spectral-angular distribution of radiation is obtained. It is shown that the angular distribution of radiation can be made narrower by using two gratings instead of one, and radiation intensity can be manipulated by parallel relative shift of gratings. The obtained results are of great importance for the research and development of high power radiation sources based on volume free-electron lasers.

This article analyzes the main problems of urban public spaces, because today public spaces can determine the future of cities. It is noted that parks are multifunctional public spaces in the urban environment, as they are an important element of the citywide system of landscaping and recreation, perform health, cultural, educational, aesthetic and environmental functions. The article notes that the need for easily accessible and well-maintained urban parks remains, however, the state of parks in many cities of Russia remains unsatisfactory, requiring reconstruction. A brief historical background of the Park of Culture and Rest of the Soviet period in Omsk is expounded, the analysis of the existing territory of the Park is presented. It is revealed that the Park, being the largest public space in Omsk, does not meet the requirements of modern urbanism, although it represents a great potential for designing the space for the purpose of recreation of citizens. Performed functional zoning scheme of the territory of the Park in question, where its division into functional areas destined for active recreational users of the Park is presented, considered the interests of senior citizens, people with limited mobility, etc. Reconstruction of Parks of the Soviet period can provide the city with additional recreational opportunities, as well as increase its tourist attractiveness.

Currently, the problem of early rehabilitation of stroke patients is important, since in terms of the prevalence of cerebrovascular diseases and disability after suffering a stroke, Russia is one of the first places in the world. The complex of medical rehabilitation of such patients should provide for the early and most complete restoration of all body functions, patient education for lost skills, re-socialization of the patient and improvement of the quality of life. One of the factors contributing to a significant reduction in the quality of life after a stroke is the development of chronic constipation. The article reflects the modern methods of correction of chronic constipation in patients with limited mobility.

Limited Mobility

The article describes the experience of clinical testing of the personal telemedicine system (PTS) ‘Obereg’ for remote monitoring of patients with the consequences of severe conditions in leading Russian clinics. It is shown that such patients are at high risk of complications when transferred from the ICU to a normal ward with limited medical supervision and lack of instrumentation. The use of remote monitoring using the personal telemedicine system ‘Obereg’ allows to solve this problem. The results of the use of PTS ‘Obereg’ for the organization of monitoring in the home patronage of patients with limited mobility are presented. It is indicated that such devices should be used in an emergency situation similar to a coronavirus pandemic to monitor patients who are in infectious boxes and on home treatment.
