    The formation of food liquid medium structures containing at least 70 % of disperse particles with high dispersiveness has been considered. The possible formation mechanisms of food liquid medium structure when slow (hydrodynamic) and quick (acoustic) processes create favorable conditions for cavitation have been studied. The possibility to control these processes for initiation of mechanical and kinetic reactions that change the structure of the medium has been demonstrated. The invert syrup has been selected as the study object. The change in the invert syrup structure before and after such cavitation treatment has been recorded with the use of metallographic microscope Nikon Eclipse MA100. The decrease in disperse phase sizes from 2–3 µm to 0.1–0.4 µm along with establishing the high uniformity of component distribution as compared to the syrup without cavitation process treatment has been detected. The formation of food liquid medium structures containing at least 70 % of disperse particles with high dispersiveness has been considered.

    Many factors contributing to the formation of a group of sickly children were analyzed according to the modern statistical mathematical methods. In this paper we consider the role of the living and environmental factors. It should be emphasized that all 143 (120 children made up observation group and 23 the control group) observed the child live in good conditions in socially-secured families.На основании современных статистических математических методов проведен анализ многих факторов, способствующих формированию группы часто болеющих детей (ЧБД). В настоящей статье рассмотрена роль жилищно-бытовых и экологических факторов. Следует подчеркнуть, что все 143 (120 детей группы наблюдения и 23 — группы контроля) наблюдаемых ребенка проживали в хороших условиях и в социально благополучных семьях

    Mathematical Model of Electrodiffusion, Dissociation and Recombination in the Diffusive Layer

    We study a mathematical model of electrochemical processes in the thin diffusive layer of polymer electrolyte between the electrode and the bulk. We consider diffusion, migration, dissociation and recombination of positive and negative ions in the electric field that take place in this region under various boundary conditions. We demonstrate that the unique stable steady state of the electrochemical system is determined by the ratio of dissociation to recombination. This state attracts time-dependent solutions of the model, but their convergence strongly depends on the electroneutrality of the bulk

    Background. Honeysuckle is a promising berry crop for food and medical uses, which has recently become increasingly popular. Searching for sources with high content of bioactive substances to obtain new fruit cultivars with improved chemical composition continues to be relevant. Anthocyanin content and composition in honeysuckle cultivars depend on many factors, including plant reproduction conditions (temperature and humidity). Studying chemical composition of Siberian honeysuckle cultivars grown under the conditions of Western Siberia will make it possible to identify sources of high BAS content for various uses.Materials and methods. The target materials of the study were fruits of 21 honeysuckle cultivars grown in Western Siberia before and after freezing. The qualitative and quantitative composition of anthocyanins was assessed in ethanol extracts of honeysuckle fruits using HPLC technique.Results. The content of anthocyanins was higher in the fruits of honeysuckle grown in Western Siberia compared with the published data for the same cultivars reproduced in Belgorod Province (Central Black Earth Region). After freezing, the anthocyanin level in honeysuckle fruits remained the same and in some cases even increased.Conclusions. The obtained data helped to ascertain that honeysuckle fruits reproduced in Western Siberia are valuable sources of such bioactive compounds as anthocyanins

    143 children and 376 of their family members were examined for the study of intrafamilial infection. The study revealed that in the families of the studied sickly children (SC) 100% of mothers, 83,3% of fathers, 100% of siblings and 100% of nannies were infected. Herpes viruses: EBV (55,8%), CMV (50,8%), HHV VI (21,7%) in combination with intracellular pathogens (Chlamydia and Mycoplasma) were prevalent in the sickly children. Examination of the family members revealed presence of the same pathogens. Control group differed significantly and reliably from the group of sickly children. There were not many infected children, no acute forms of diseases; monoinfection predominated. Было обследовано 143 ребенка и 376 членов семей для изучения внутрисемейного инфицирования. В группе часто болеющих детей (ЧБД) было выявлено инфицированных 100% матерей, 83,3% отцов, 100% сибсов и 100% нянь. У ЧБД преобладали герпесвирусы: ЭБВ (55,8%), ЦМВ (50,8%), ГВЧ VI (21,7%) в сочетании с внутриклеточными патогенами (хламидиями и микоплазмами. При обследовании всех членов семей было выявлено инфицирование практическими теми же возбудителями. Группа контроля значительно и достоверно отличалась от группы ЧБД небольшим количеством инфицированных детей, отсутствием острых форм и преобладанием моноинфицирования.

    Currently, acute respiratory infection (ARI) and Herpes virus infection are widely prevalent in children and adults. Clinical presentations and course, characterization of ARI and Herpes virus infection, groups of immunomodilating drugs and current individualized treatment approach are reviewed in this article.Острые респираторные вирусные (ОРВИ) и герпесвирусные инфекции стали одними из самых распространенных заболеваний как среди детей, так и среди взрослых. Представлены клинические особенности течения и классификации ОРВИ, герпетических инфекций, иммуномодулирующих препаратов, а также возможности современного лечения с учетом индивидуального подхода, особенно у часто болеющих детей и взрослых
