    © Medwell Journals, 2017. The study reviews the development of strategic management accounting in the system of strategic management of agriculture. The following aspects are being presented: models of management and strategic management accounting, accounting matrix of interactions between subsystems and functional tools of management accounting and the conceptual model of the strategic subsystem development. The model of differentiation of management accounting into subsystems of operational and strategic management accounting is proposed. Conceptual solutions for the development of strategic management accounting in agriculture are developed. It is hereby concluded that strategic management accounting is a modified form of management accounting which focuses on study of both internal and external environment, data collection, its processing, design and transfer of strategic managerial decisions to the management system as well as monitoring and evaluation of their execution efficiency. The importance of the developed methodological aspects and conceptual solutions in development of strategic management accounting is defined for the theory and practice of management accounting in agriculture

    Effects of female sexual chemosignals on mucosal immunity in BALB/c and C57BL/6 male mice

    The immune response to immunogenic stimuli depends on various factors like cytokine context, way of entry, and immune status of the organism. In mice, female chemosignal entry into the male organism via the respiratory system causes activation of the mucosal immune response, which leads to the development of enhanced resistance to infections and is of adaptive value. However, the activation of mucosal immunity depends on the genetic predispositions of the immune response. BALB/c and C57BL/6 are prototypically Th2- and Th1-type mouse strains, respectively, therefore, they can serve as perfect model organisms for studying mechanism of lung mucosal immune activation in response to female chemosignals. Respiratory tract mucosal immune response to intranasal application of LPS, urea solution, saline and female urine used as a chemosignal was investigated in BALB/c and C57BL/6 male mice. Application of both female urine and LPS increased total white blood cell count and protein concentration in bronchoalveolar lavage fluid in BALB/c, but not in C57BL/6 male mice, suggesting an important role of Th2 pathway in lung mucosal immune response. At the same time, urine application provoked a significantly lower plasma corticosterone elevation than LPS. Thus, sexual signals associated with infection risks provide genotype-dependent mobilization of innate immunity without significant activation of physiological stress mechanisms

    Despite the advances in medicine, about 4 million children under the age of 6 months die annually around the world due to infection, which is 450 deaths per hour (UNISEF, 2009). The degree of development of the immune system of children born in time is determined by many factors, including the immunogenetic similarity or difference of mother and fetus organisms, which, in turn, is due to the genotypes of mating pairs, as well as the selection of surrogate mothers during in vitro fertilization. From our review of the literature, it follows that immunogenetic interactions of mother and fetus organisms, which occur at all stages of pre- and postnatal development, have a signifcant effect on the resistance of offspring to infections and allergens. Before implantation, the mother’s immune responses are formed under the influence of semen fluid antigens, leukocytes and cytokines, as well as under the influence of the genes of the major histocompatibility complex, which are expressed in embryos at the stage of two cells. After implantation, transplacental transfer of immunoglobulins and immunocompetent cells becomes of immunomodulating importance. It is important to emphasize that, although substances with a high molecular weight usually do not pass through the placenta, this rule does not apply to immunoglobulin G (IgG), which, with a molecular weight of about 160 kDa, overcomes the transplacental barrier due to binding to the fetal Fc receptor. The level of IgG in newborns usually correlates with the level of maternal antibodies. During the period of natural feeding, the immune protection of newborns is provided by the mechanisms of innate immunity and the factors of humoral immunity of mothers. It has been shown that immunoglobulins from the milk of many animal species are transferred through the neonatal intestinal epithelium to the blood. Since breast milk contains large amounts of various immunoactive components, including proteins, cytokines, hormones, immunoglobulins, exosomes containing micro-RNA, and viable immune cells, the immunomodulating effects of breast milk persist even after elimination of maternal immunoglobulins from the blood of the offspring, up to maturation. Analysis of a large body of experimental data shows that the study of mechanisms of “motherfetus” and “mother-newborn” interactions are the basis of a knowledge base needed to fnd means of life-long directed modulation of the descendants’ immune status

    Aim. To estimate the economic damage by acute coronary syndrome (ACS) in Russia in 2006-2009. Material and Methods. Direct costs and economic losses associated with ACS were estimated. The structure of direct costs includes the costs of hospitalization, medical emergencies, out-patient visits, high-tech medical care, as well as drug therapy in outpatient treatment. Losses in the economy associated with ACS include loss of gross domestic product due to death in working-age, temporary disability and payments of disability benefits. Estimation of economic damage by cardio-vascular diseases was based on analysis of Russian Ministry of Health official statistics. Results. Approximately 520,000 cases of ACS are registered annually (36,4% - myocardial infarction, 63,6% - unstable angina). Trend to increased mortality from myocardial infarction, especially among women, was found during the analyzed period. From 2000 to 2009 this index rose from 34.9 to 41.1 per 100,000 of population among women, and from 52.3 to 55.9 per 100,000 of population among men. Total direct costs of health care for patients with ACS in 2009 amounted to almost 21 billion rubles, and indirect – 53.5 billion rubles. The total economic damage by ACS in Russia in 2008-2009 exceeded 70 billion rubles per year. Conclusion. ACS in Russia is connected with significant social and economic damage. Most part of this damage is indirect losses in economy due to premature mortality of working aged men

    Pig is the most promising species for transplantation of organs and cells into humans, although implementation of xenotransplantation in clinical practice has been hindered by the risk of infecting the recipient with zoonotic infectious diseases. Porcine endogenous retroviruses (PERV) are capable of incorporating copies of DNA into the genome of a host cell. Based on the nucleotide sequence of the envelope gene (env), three main types of pig retrovirus, PERV-A, PERV-B and PERV-C, have been recognized, with PERV-A and PERV-B having the capability of infecting human cell lines in vitro. Selection for animals with low copy number of retroviruses in the genome using simple phenotypic indications is required for the widespread implementation of xenotransplantation. The objective of this study was to evaluate the correlation between PERV-A env gene copy number and hematological parameters, gender and coat  color in miniature pigs of the Institute of Cytology and Genetics (ICG) SB RAS. Reference values for eighteen blood parameters of miniature pigs were determined, including white blood cell count (WBC), red blood cell count (RBC), platelet count (PLT), absolute (LYM#) and relative (LYM%)  lymphocyte counts, absolute (MID#) and relative (MID%) monocyte, basophil and eosinophil counts, absolute (GRA#) and relative (GRA%) granulocyte counts, hematocrit (HCT) and thrombocrit (PCT), mean cell volume (MCV) and mean platelet volume (MPV). Males had significantly higher reference values for WBC, MID#, GRA# and red cell distribution width (RDW-CV) as compared to females. The mean corpuscular hemoglobin  concentration (MCHC) and platelet distribution width (PDW-CV) were significantly higher in female animals. No correlation between PERV-A env gene copy number and the coat color of  animals was detected, suggesting that retroviral insertion sites and genes that determine the coat color of miniature pigs, namely KIT (chromosome 8) and MC1R (chromosome 6), are either located far apart on same chromosome or on different chromosomes. The copy number of PERV-A env gene in males was lower than in females. Presence of multiple copies of PERV-A on the X-chromosome is the most probable cause of such gender-related differences in miniature pigs. Thus, male miniature pigs of ICG SB RAS should be the source of material for xenotransplantation

    In recent years, the microalgae (Chlorella vulgaris) have increasingly attracted great interest as a potential source of pharmacologically active compounds. Showing anticoagulation, antioxidant and antitumor activities of Chlorella revealed its hypotensive properties. The aim of this study was to evaluate the effects of Chlorella suspension on the weight of the animals, their moving activity, and erythropoiesis. The study was performed on males and females of ICR mice. The animals from the experimental group drank only the Chlorella suspension during 3 weeks and were given standard food. Control animals drank during this period only water and had the same food. The body weight of males in the control and the experimental group with Chlorella did not change, while females in the experimental group showed an increase of body weight in a week. A similar pattern was obtained for estimation of animal body weight changes relative to food consumption. The number of red blood cells in females and males from group with Chlorella increased only after 3 weeks after the start of the experiment. Hemoglobin also increased only after 3 weeks after the start of Chlorella consumption, but only for females. All groups of animals had the same motor activity during experiment. Blood sampling resulted in a reduction of activity in control males and females as well as in males with Chlorella. The motor activity of females with Chlorella after blood sampling did not change. So, consumption of the Chlorella suspension by females leads to more effective digestion and resulted in increased body weight, improved erythropoiesis resulted in increased red blood cells and hemoglobin and also increased their resistance to acute stress. The males in the same situation increased only the erythropoiesis

    Efficient chimeric mouse production using a novel embryonic stem cell line

    Embryonic stem cells are commonly used for generation of transgenic mice. Embryonic stem cells could participate in the development of chimeric animals after injection into a blastocyst. Injection of genetically modified embryonic stem cells could lead to germ line transmission of a transgene or genomic modification in chimeric mice. Such founders are used to produce transgenic lines of mice. There are several projects dedicated to production of knock-out mouse lines (KOMP Repository, EUCOMM, Lexicon Genetics). Never-theless, there is a need for complex genome modifications, such as large deletions, reporter genes insertion into the 3’ gene regulatory sequence, or site-specific modifications of the genome. To do that, researchers need an embryonic stem cell line that is able to participate in chimeric animal formation even after prolonged culture in vitro. Several lines of mouse embryonic stem cells were produced in the Laboratory of Developmental Genetics of the Institute of Cytology and Genetics SB RAS. We tested DGES1 cell line (2n = 40, XY) (129S2/SvPasCrl genetic background) for chimeric mice production at the Center for Genetic Resources of Laboratory Animals at ICG SB RAS. Embryonic stem cells were injected into 136 blastocysts (B6D2F1 genetic background), which were transplanted into CD-1 mice. Among 66 progeny, 15 were chimeric, 4 of which were more than 80 % chimeric judged by coat color. All chimeras were males without developmental abnormalities. 10 of 15 males were fertile. Microsatellite analysis of the progeny of chimeric mice revealed embryonic stem cell line DGES1 contribution to the gamete formation. Thus, a novel DGES1 embryonic stem cell line could be efficiently used for transgenic mouse production using B6D2F1 blastocysts and CD-1 recipients

    To identify body systems subject to epigenetic transformation during in vitro fertilization (IVF), comparative morphological and functional studies were performed on sexually mature offspring of outbred CD1 mice, specific-pathogen-free (SPF), obtained by IVF (experiment) and natural conception (control). The studies included assessment of age-related changes in body weight and composition, energy intake and expenditure, and glucose homeostasis. To level the effects caused by the different number of newborns in the control and in the experiment, the size of the fed litters was halved in the control females. Males obtained using the IVF procedure were superior in body weight compared to control males in all age groups. As was shown by analysis of variance with experiment/control factors, gender, age (7, 10 and 20 weeks), the IVF procedure had a statistically significant and unidirectional effect on body composition. At the same time, IVF offspring outperformed control individuals in relative fat content, but were behind in terms of lean mass. The effect of the interaction of factors was not statistically significant. IVF offspring of both sexes had higher fat to lean mass ratios (FLR). Since adipose tissue contributes significantly less to total energy intake compared to muscle, the main component of lean mass, it is not surprising that at the same level of IVF locomotor activity offspring consumed less food than controls. When converted to one gram of body weight, this difference reached 19 %. One of the consequences of reduced utilization of IVF energy substrates by offspring is a decrease in their tolerance to glucose loading. The integral criterion for the effectiveness of restoring the initial glucose level is the area under the curve (AUC), the value of which was 2.5 (males) and 3.2 (females) times higher in IVF offspring compared to the corresponding control. Thus, the totality of our original and literature data shows an increase in the risk of metabolic disorders in IVF offspring, which is confirmed by epidemiological studies of a relatively young cohort of people born using assisted reproductive technologies

    Aim. Research of the association of heart rate variability (HRV) with the level of psychosocial stress (PS) and other indicators of the risk of cardiovascular diseases in a sample of 41-44-year-old men living in Moscow.Material and methods. A total of 299 men aged 41-44 years were examined. The study included a clinical examination and a survey using a standard questionnaire. The categorization of risk factors (RF) for cardiovascular diseases (CVD) was carried out in accordance with generally accepted criteria The psychosocial stress was assessed using the Reeder scale. Depending on the psychosocial stress level, all surveyed men were divided into 3 groups by terciles: group 1 (3,28-4,0 points) – mild stress, group 2 (2,71-3,14) – moderate stress, group 3 (1,28-2,57) – severe stress. The analysis of HRV was performed on the basis of a short recording of an electrocardiogram using the original software package.Results. Nonparametric ANOVA showed that the mean [M (95% CI)] values of the HRV time domain (SDNN, rMSSD and the state of regulatory reserves) were lower in the group of men with high PS compared with the group with low PS [25.3 ms (20.9-29.7) versus 40.5 ms (30.7-50.3), p=0.007; 29.5 ms (24.6-34.3) versus 49.5 ms (36.7-62.3), p=0.030; and 46.7 (44.7-48.6) versus 49.7 (48.1-51.4), p=0.019; respectively]. On the contrary, the mean values [M (95% CI)] of the integral indicators of HRV (SI and IVR) were higher in the group of men with high PS [635.8 c.u. (556.2-715.4) versus 488.9 (423.8-554.1), p=0.005; 1172.6 (1045.1-1300.1) versus 904.7 (790.0-1019.4), p=0.003; respectively]. The results of correlation and multiple regression analysis confirmed that these HRV indicators are statistically significantly associated not only with PS, but also with other indicators (age, waist / hip ratio, diastolic blood pressure). However, their predictive value turned out to be low, and the proportion of the explained variance of HRV indices ranged from 2.5 to 13.1%.Conclusion. The weakening of the autonomous regulation of the heart rate with a decrease in the activity of the parasympathetic link, the activation of the central circuit of regulation with the prevalence of sympathetic influences, a decrease in the functional reserves of the heart rate regulation system are associated with an increase in the level of PS and other indicators of the risk of cardiovascular diseases

    Aim. To study the excessive mortality during the winter (EMW) from all causes and CVD, monthly values of mortality; to evaluate social and economic harm due to EMW in Moscow.Material and methods. The calculation of EMW (%) was done for Moscow by the mortality from all causes and from CVD by a special equation. For monthly values of mortality we estimated the average range per month by absolute number of the deaths — absolute parameters of mortality by every analyzed year were ranged from 1 to 12, and mean value of the range was calculated.Results. Mean EMW per 8 years was 5,1%, for CVD higher — 8,8%. In Moscow there is an influence of the anomaly heat of 2010 — EMW was 4,5% from all causes, from CVD — 6,0%. Maximum number of deaths was registered in January and march. Gross EH by 2007-2013 from EMW was 7,9 billion rubles in Moscow.Conclusion. A significant part of EMW are the deaths from CVD. The amount of EH from EMW has confirmed the shown previously relation from two factors — number of deaths and size of GRP in region. For Moscow — the capital of Russia, having the highest values of economic development, the harm, that is quite significant, grounds the necessity of investments into excessive mortality and search for effective by decrease of mortality in winter time
