Improving Health Industries by the Supply-Chain Policy

Abstract— the article deals with issues of the policy in the sphere of protection of a Supply-Chain management’s rights and legitimate interests in the health centres. The issues of protection of the rights of Supply-Chain management in the field of health care revealed. In today's global and national economy, businesses are increasingly relying on outsourcing some of their activities and processes. Therefore, more and more companies at the Supply-Chain level, in specific networks, operate and compete with their suppliers and service providers. This process of outsourcing and the growing importance of supply chains has its consequences in the working conditions and health and safety of workers of supply companies and contractors. There are two main networks of Supply-Chain or relationships between companies and members of their supply chain: the main network (a company and suppliers of its specific goods and materials) and the secondary network (a company and its contractors and subcontractors special services such as activities Maintenance, construction, cleaning or catering This report provides an overview, analysis, conclusions and recommendations on how to upgrade health centers through the above Supply-Chain networks

Вирус Эпштейна–Барр у этнических татар: инфицированность и сиквенсные варианты онкогена LMP1

Objective of the investigation was to study the infection of ethnic Tatars with the Epstein–Barr virus (EBV) and to analyze the genetic structure of the oncogene of the virus, the latent membrane protein 1 (LMP1), in the virus strains of Tatar origin. Materials and methods. The materials for the study were samples of boucle flushes of 60 students from the Kazan State Medical University who are ethnic Tatars (Tatars no less than in the 3rd generation). Amplified from DNA of boucle flushes the nucleotide sequences of the LMP1 samples translated into DNA amino acid sequences, have undergone classification based on the well-known and widely used in literature the R.H. Edwards et al. classification. Results. The analysis of nucleotide and deductive amino acid sequences of the 41 LMP1 amplicons revealed their homology with only three gene variants from the R.H. Edwards et al. classification (1999): 95.8/A (29.3 %; 12/41), Med– (14.6 %; 6/41) and China1 (7.3 %, 3/41). Such variants of LMP1 as Alaskan, Med+, Chinа2, China3 and NC, were not found. Among the LMP1 samples of Tatar origin in 20 cases (48.8 %), the composition of the mutations found did not allow them to be assigned to any of the oncogene variants listed above. Out of this number, in 7 (17.1 %) cases a mono group of LMP1 samples was found, differing not only from representatives of the Slavs, inhabitants of the European part of Russia, but also from other Kazan samples, and was designated as LMP1-TatK. The remaining 13 samples of LMP1 (31.7 %), not belonging to any of the known classifications, formed the group designated by us as an LMP1 group beside the classification (LMP1BC). Conclusion. Continuation of the study of the molecular-biological and functional properties of LMP1 in TatK and BC groups, which constitute 48.8 % of the number of gene samples studied, and an analysis of the peculiarities of the ethnic Tatar genotype, will probably help to clarify whether certain EBV strains influence morbidity and mortality in Tatar population with malignant neoplasms, which include EBVassociated cases.Цель исследования – изучение инфицированности вирусом Эпштейна–Барр (ВЭБ) этнических татар и анализ генетической структуры онкогена вируса, латентного мембранного белка 1 (LMP1), в штаммах вируса татарского происхождения. Материалы и методы. Материалом для исследования служили буккальные смывы 60 студентов Казанского государственного медицинского университета, являющихся этническими татарами (не менее чем в III поколении). Выделенную из смывов ДНК использовали для амплификаци LMP1. Амплифицированные из ДНК буккальных смывов нуклеотидные последовательности образцов LMP1, транслированные в аминокислотные последовательности, подверглись классификации на основании известной и широко используемой в литературе классификации R.H. Edwards и соавт. Результаты. Анализ нуклеотидных и транслированных аминокислотных последовательностей 41-го ампликона LMP1 выявил их гомологию только с 3 вариантами гена из классификации R.H. Edwards и соавт.: 95.8/А (29,3 %; 12/41), Med– (14,6 %; 6/41) и China1 (7,3 %; 3/41). Такие варианты LMP1, как Alaskan, Med+, Chinа2, China3 и NC, не обнаружены. В остальных 20 случаях (48,8 %) спектр обнаруженных мутаций в образцах LMP1 татарского происхождения не позволил их отнести ни к одному из перечисленных выше вариантов онкогена. Из них в 7 случаях (17,1 % всех исследованных образцов) обнаружена моногруппа вариантов LMP1, отличающаяся не только от представителей славян, жителей европейской части России, но и от других казанских образцов, и обозначенная нами, как LMP1-TatK. Остальные 13 образцов LMP1 (31,7 %), не относящихся ни к одной из известных классификаций, сформировали группу, обозначенную нами, как группа LMP1 вне классификации (LMP1ВК). Заключение. Дальнейшее изучение молекулярно-биологических и функциональных свойств LMP1 в группах ВК и TatK, составляющих 48,8 % от числа изученных образцов онкобелка, и анализ особенностей генотипа этнических татар, вероятно, позволят выяснить, оказывают ли определенные штаммы ВЭБ влияние на показатели заболеваемости и смертности злокачественными новообразованиями, в состав которых входят ВЭБ-ассоциированные случаи, у татарского населения

Analysis of the Models of Motion of Aqueous Solutions of Polymers on the Basis of Their Exact Solutions

The qualitative properties of solutions of a hereditary model of motion of aqueous solutions of polymers, its modification in the limiting case of short relaxation times, and a similar second grade fluid model are studied. Unsteady shear flows are considered. In the first case, their properties are similar to those of motion of a usual viscous fluid. Other models can include weak discontinuities, which are retained in the course of fluid motion. Exact solutions are found by using the group analysis of the examined systems of equations. These solutions describe the fluid motion in a gap between coaxial rotating cylinders, the stagnation point flow, and the motion in a half-space induced by plane rotation (analog of the Karman vortex). The problem of motion of an aqueous solution of a polymer in a cylindrical tube under the action of a streamwise pressure gradient is considered. In this case, a flow with straight-line trajectories is possible (analog of the Hagen-Poiseuille flow). In contrast to the latter, however, the pressure in the flow considered here depends on all three spatial variables

The Problem of Filling a Spherical Cavity in an Aqueous Solution of Polymers

The problem of filling a spherical cavity in a liquid has attracted the attention of many authors. The study of bubble behavior in liquid allows to estimate the consequences of cavitation processes, which can lead to the intensive destruction of the material surface. Regarding this connection, it becomes necessary to study the influence of impurities, including polymeric additives on the strengthening or suppression of cavitation. In this paper, this problem is considered in three models of a relaxing fluid. It is shown that for all models, the cavity filling time is finite if the surface tension is not equal to zero. This result was previously established for the cases of ideal and viscous fluids. However, the relaxation factor can significantly change the flow pattern by slowing down the filling process and lowering the level of energy accumulation during the bubble collapse

MODERN EPIDEMIOLOGICAL CHARACTERISTICS OF NOROVIRUS INFECTION IN MOSCOW

Aim. Norovirus infection (NVI) epidemiological characteristics evaluation in Moscow at municipal and district levels. Materials and methods. A retrospective analysis of NVI incidence rate was conducted according to the 2009 - 2016 state statistical reporting forms data. Results. In 2009 - 2016 NVI incidence rate has a trend to increase in Moscow, either at municipal and district levels. NVI cases were registered among children mostly (78% in the SEAD of Moscow, 80% in Moscow and 81% in Russia), at the same time adults proportion of NVI incidence rate increased significantly (up to 42,7% in Moscow and 13,9% in the Russian Federation) by 2016. The morbidity dynamics in different child population age groups was effected by the outbreaks cases. Totally in 2011 - 2016 33 outbreaks were registered in Moscow (24,3% from all acute diarrheal infection outbreaks in Moscow for the same period), where 64,3% with nonpercutaneous channel of infection and 35,7% alimentary. Outbreaks were more often recorded in children’s organized collectivity (69,7%). Conclusion. Nowadays in Moscow there is an NVI incidence increase trend is evidenced, with an increase of the adult population proportion in morbidity structure. At this stage, main contribution to group morbidity was made by children 7 - 14 and 15 - 17 years old. One of the reasons for the NVI incidence rate growth in Moscow (2016) could possibly be the lack of effective prevention measures. Actually, specific NVI diagnostics provided only in outbreaks, due to the lack of routine diagnostic tools. The main reason for the NVI group morbidity effective disease area formation is still sanitary and anti-epidemic regime violation at sites and facilities
