The Influence of Combined Sterilization Factors on the Structural and Functional Characteristics of Bone Implants.

The results of a comprehensive study of the patterns of structural and functional changes in bone tissue samples after combined (ozone + radiation) sterilization are presented. The study used a different approach to the sterilization process with selective ozone or radiation exposure and an integral, combined one, based on a combined ozone-oxygen treatment of bone samples at the first stage and radiation at the second. The methods of IR spectroscopy, scanning electron microscopy with a prefix for elemental analysis, atomic force microscopy, and mechanical analysis with determination of elastic-plastic properties (Vickers microhardness index) were used in the work.

Biomedical Applications of Contemporary Ozone Technologies.

An overview of the state and development of ozone therapy technologies in modern biomedical applications, as well as relevant apparatus and equipment, is presented based on reports at the XV International Scientific Conference "Physics and Radioelectronics in Ecology and Medicine - PhREME'2022." Descriptions and technical characteristics of ozone generators used in various applications, from household to clinical use, are given. Data from a comparative analysis of the main parameters of Russian- and foreign-made equipment for ozone therapy, as well as examples of promising innovative developments, are addressed.

[Dietary changes in males from adolescence to adulthood: results of a 28-year prospective study].

Dietary pattern usually changes with age; however, certain dietary habits may remain constant. of this study was to analyze dynamic changes in the dietary pattern of males from adolescence to adulthood during a 28-year prospective follow-up. .

Association of Vital Exhaustion with Risk Factors for Cardiovascular Diseases, Quality of Life and Lifestyle in 41-44-Year-Old Muscovite Men.

(1) Background: Vital exhaustion (VE) is no less of an important risk factor (RF) for cardiovascular diseases (CVD) and cardiovascular events than the well-known RFs. Insufficient knowledge of the relationship between VE and CVD RF, quality of life, and lifestyle was the rationale for this study. (2) Methods: We examined 301 Muscovite men 41-44 years of age.

A fast and accurate radiative transfer model for aerosol remote sensing.

After several decades' development of retrieval techniques in aerosol remote sensing, no fast and accurate analytical Radiative Transfer Model (RTM) has been developed and applied to create global aerosol products for non-polarimetric instruments such as Ocean and Land Colour Instrument/Sentinel-3 (OLCI/Sentinel-3) and Meteosat Second Generation/Spinning Enhanced Visible and Infrared Imager (MSG/SEVIRI). Global aerosol retrieval algorithms are typically based on a Look-Up-Table (LUT) technique, requiring high-performance computers. The current eXtensible Bremen Aerosol/cloud and surfacE parameters Retrieval (XBAER) algorithm also utilizes the LUT method.

Global diffuse attenuation derived from vibrational Raman scattering detected in hyperspectral backscattered satellite spectra.

Underwater light field characterization is of importance for understanding biogeochemical processes and heat budget of the global oceans, which are impacting and reacting to climate change. Vibrational Raman Scattering (VRS) was retrieved from backscattered radiances measured by three different hyperspectral satellite sensors, SCIAMACHY, GOME-2, and OMI, using Differential Optical Absorption Spectroscopy (DOAS). Diffuse attenuation coefficient (Kd) in the blue spectral range (390 to 426 nm) was derived from the VRS signal via a look-up-table established through ocean-atmosphere coupled radiative transfer modeling.

Retrieval of aerosol optical properties using MERIS observations: Algorithm and some first results.

The MEdium Resolution Imaging Spectrometer (MERIS) instrument on board ESA Envisat made measurements from 2002 to 2012. Although MERIS was limited in spectral coverage, accurate Aerosol Optical Thickness (AOT) from MERIS data are retrieved by using appropriate additional information. We introduce a new AOT retrieval algorithm for MERIS over land surfaces, referred to as eXtensible Bremen AErosol Retrieval (XBAER).

[Relationship between carotid artery intima media thickness and risk factors of cardiovascular diseases in young men].

Positive correlation between age, leading risk factors of cardiovascular diseases (CVD), and carotid artery intima-media thickness (IMT) has been shown in numerous studies. Contingent of the present work was a part of long term cohort study initiated in 1983. We included in analysis data from 233 men in 120 of whom we measured IMT of right and left common carotid arteries.

[Infectious complications of combined injuries in large-scale catastrophes].

Main forms of infectious complications and their causes in large-scale catastrophes and baseline conditions were studied based on examination of 1463 casualties with combined injuries. The following parameters were analysed: mean injury severity (ISS and APACHE-II systems), shock severity, and blood volume deficit. The frequency of infectious complication of combined injuries was estimated with reference to severity of the major trauma and the number of affected body regions.

[Primary prevention of cardiovascular diseases: long term results of five year long preventive intervention in 12-year old boys (ten year prospective study)].

In a longitudinal cohort (prevention group, n=213, comparison group, n=163) of 10-year prospective follow-up we addressed efficacy of 5-year-long multifactor preventive intervention, conducted in a sample of population of 12 year old boys. Preventive intervention was carried out both at populational level and among persons with risk factors of development of cardiovascular diseases with the use of group, individual, and partly family approaches, and was directed at rationalization of nutrition, elevation of physical activity and prevention of harmful habits. During first 3 years of prevention we succeeded to achieve stable statistically significant lowering of mean levels of total cholesterol, low density lipoprotein cholesterol, triglycerides, and atherogeneity index, as well as to affect fatty component of body mass (skinfold thickness).
