For the purpose of stating the need in medical and preventive care programs for people under long-term exposure to anthropogenic chemical pollutants impact, assessment of harmful effects on health of the Loctevsky district (the Altai Krai) population due to emissions of ore-dressing plant tailing dump has been performed. The harmful health effects assessment was carried out using the health risk assessment methodology and epidemiological research methods. According to the study results, there have been determined unacceptable risks of progress of the respiratory system disorders, blood diseases and systemic disturbances associated with exposure to copper oxide (II) and particulates. There have been established statistically significant cause and effect relationships between risk factors and blood diseases including anaemia and chronic diseases of tonsils and adenoids in children; asthma in adults. Economic losses associated with actual prevalence have been assessed. According to the study results, it is necessary to develop and implement medical and preventive care programs for people under long-term exposure to the studied substances. © Northern State Medical University.

A submodel of the digestive system is developed within the framework of multilevel model predicting the evolution of human functional disorders under environment influence. The article is dedicated to some problems associated with the submodel of food flow in the stomach. Materials in details is devoted to the reconstruction algorithm of 3D form andtroduodenal part of the digestive tract, based on ultrasonography results, and to the algorithm of the mesh node displacement caused by the antral contraction wave propagation and the pyloric sphincter motor activity. 3D form obtained and mesh configuration changing algorithm translated to program code are used for the flow calculation in antroduodenal part of the tract. Flow characteristics of one/two phased medium with opened/closed pyloric sphincter are analyzed considering functional disorders of the stomach motility; results are compared with 2D case. Further development ways of the stomach submodel and the digestive system model are noted: considering functional disorders of the pyloric sphincter, periodicity disorders of the antral contraction wave propagation in the stomach, processes of the digestive juice secretion, absorption of substances into the circulatory system. © 2015.

Clinical medicine and public health would benefit from simplified acquisition of biological samples from patients that can be easily obtained at point of care, in the field, and by patients themselves. Microneedle patches are designed to serve this need by collecting dermal interstitial fluid containing biomarkers without the dangers, pain, or expertise needed to collect blood. This study presents novel methods to collect biomarker analytes from microneedle patches for analysis by integration into conventional analytical laboratory microtubes and microplates. Microneedle patches were made out of cross-linked hydrogel composed of poly(methyl vinyl ether-alt-maleic acid) and poly(ethylene glycol) prepared by micromolding. Microneedle patches were shown to swell with water up to 50-fold in volume, depending on degree of polymer cross-linking, and to collect interstitial fluid from the skin of rats. To collect analytes from microneedle patches, the patches were mounted within the cap of microcentrifuge tubes or formed the top of V-bottom multiwell microplates, and fluid was collected in the bottom of the tubes under gentle centrifugation. In another method, microneedle patches were attached to form the bottom of multiwell microplates, thereby enabling in situ analysis. The simplicity of biological sample acquisition using microneedle patches coupled with the simplicity of analyte collection from microneedles patches integrated into conventional analytical equipment could broaden the reach of future screening, diagnosis, and monitoring of biomarkers in healthcare and environmental/workplace settings. © 2014 American Chemical Society.

Manganese oxides have been synthesized by the interaction of Mn2+ and Mn in the presence of nanoreactors: cetyltrimethylammonium bromide micelles that were not present in the final product composition. The synthesized substance is investigated using scanning electron microscopy, X-ray diffraction analysis, dynamic light scattering, the Brunauer-Emmett-Teller method, and the method of Barrett-Joyner-Halenda. It is determined that the substance under examination is a filamentous nanometer-scale material with a cross-section size up to 100 nm. The acute inhalation toxicity study is performed according to the interstate standard using the method of acute-toxicity class determination (ATC method) (OECD, Test no. 436:2008, IDT). The ATC method allows us to see that synthesized nanosized manganese oxide has an acute toxicity property when inhaled as an aerosol. Upon 4-h exposure to Wistar rats weighing 190 ± 10g, CL50 is 0.12 mg/L. The clinical picture of acute intoxication is characterized by irritation, neurotoxic effects, and respiratory depression. According to CL50 (>0.05–0.5), mg/L criterion, synthesized nanosized manganese oxide belongs to hazard class 2 in accordance with Globally Harmonized System of Classification and Labelling of Chemicals (GHS). © 2015, Pleiades Publishing, Ltd.

Indoor Air 2014 - 13th International Conference on Indoor Air Quality and Climate | Year: 2014

A study of the correlation of indoor air pollution with formaldehyde and deterioration of the children's health. In the children living in the houses with increased levels of indoor air formaldehyde to 36 MPC d.a. (Maximum Permissible Concentration daily average) (at average 0.039 mg/m3) respiratory diseases and diseases of immune system related to its chronic exposure were diagnosed. Average formaldehyde content in the blood of examined children was 3.2 times higher than in the comparison group, 2.6 times higher than the background regional level. In 83.3% of the examined children acute and chronic inflammatory diseases of the oral pharynx and nasopharynx were diagnosed, including proceeding with hypertrophy of lymphoid tissue, 1.2-1.3 times higher than in the comparison group. The causal link between the concentration of formaldehyde in the blood and morbidity of children with respiratory diseases, rhinomanometry indicators was established - total volume flow and total resistance, level of IgE specific to formaldehyde.

In this article we consider a novel fast approach based on wavelet transform for edge detection and simplified variant of active contour method - active primitives for the image processing in the research on dust emissions from industrial enterprises. The objective of the dust emissions analysis is to determine their component composition and the fine particle size distribution (PM10 and PM2.5). The scanning electronic microscope of high resolution was used to obtain the large-scale images of dust particles. We use the images of particles in different scales as the entire imagery data. © Springer International Publishing Switzerland 2015.

A group of authors has developed a multilevel mathematical model that focuses on functional disorders in a human body associated with various chemical, physical, social, and other factors. At this point, the researchers have come up with structure, basic definitions and concepts of a mathematical model at the "macrolevel" that allow describing processes in a human body as a whole. Currently we are working at the "mesolevel" of organs and systems. Due to complexity of the tasks, this paper deals with only one meso-fragment of a digestive system model. It describes some aspects related to modeling multiphase flow in the antroduodenal portion of the gastrointestinal tract. Biochemical reactions, dissolution of food particles, and motor, secretory, and absorbing functions of the tract are taken into consideration. The paper outlines some results concerning influence of secretory function disorders on food dissolution rate and tract contents acidity. The effect which food density has on inflow of food masses from a stomach to a bowel is analyzed. We assume that the future development of the model will include digestive enzymes and related reactions of lipolysis, proteolysis, and carbohydrates breakdown. © 2016 P. V. Trusov et al.
