Degradation of higher education in Kazakhstan as an example of post-transitional crisis

It is shown, that objectives of degradation of Higher Education in most part of post-soviet countries are connected with the specific factors appeared at the economical situation appeared at the end of transitional period (transition from planned economy to market one). Decreasing of quality of higher education in such countries as Kazakhstan may be interpreted in frameworks of Baudrillard’s concept of evolution of connection between "The Sign" and "The Reality"; such interpretation directly shows that overcoming of negative trends in post-soviet countries education cannot be realized by traditional administrative instruments. The problem may be solved by taking into account concepts of institutional economy

Cytokines and local chronic inflammation in the formation of infertility in fertile age women

The purpose of the study was to examine the characteristics of the content of cytokines in the peritoneal fluid in women of reproductive age with infertility against the background of chronic inflammatory diseases of the pelvic organs in the stage of clinical remission.Material and methods. A study was conducted of 50 patients aged 23-36 years with a verified diagnosis of infertility of tubal peritoneal genesis against a background of chronic inflammatory diseases of the reproductive sphere in the stage of clinical remission. As a control group, 15 practically healthy women aged 25-37 years were examined. Concentration of cytokines TNF-a, IL-4, IL-6, IL-10, IFN-y, MCP-1 in the peritoneal fluid was measured by enzyme-linked immunosorbent assay.Results and discussion. In the main group of patients with tubal-peritoneal infertility, the activity of local inflammatory reactions is tested in the period of clinical remission of a chronic inflammatory process. This is confirmed by a significantly higher level of TNF-a, IL-4, IL-6, IFN-y, MCP-1 in the peritoneal fluid compared to the control group. The studied biologically active substances play a significant role in the development of the immune response, as well as fibroplastic processes. The results can be regarded as the latent development of the immune response in reactions to constant antigenic stimulation from the focus of chronic inflammation, which is a significant factor in the development of adhesions in the formation of infertility, and requires the inclusion of immunotropic therapy methods in treatment

AB0-incompatibility of mother and fetus: the role of anti-glycan alloantibodies in the hemolytic disease of newborns

The mother and fetus incompatibility due to Rh-factor, blood group or other blood factors can lead to hemolytic disease of the fetus and newborn (HDN). HDN is a clinical disease condition of the fetus and newborn as a result of hemolysis, when maternal IgG alloantibodies cross the placenta and destroy the red blood cells of the fetus and newborn. The child disease begins in utero and can dramatically increase immediately after birth. As a result, hyperbilirubinemia and anemia develop, that can lead to abortions, serious complications, or death of the neonates in the absence of proper therapy. The range of HDN has changed significantly now compared to previous decades. Half a century ago, HDN was considered an almost complete synonym of RhD-alloimmunization, and this was a frequent problem for newborns. By now due to the high effective of Rh-conflict prevention, immunological AB0-conflicts have become the most common cause of HDN. The review aimes to one of the main causes of jaundice and anemia in neonates at present, i.e. HDN due to immunological AB0-conflict of mother and newborn (AB0-HDN). The main participants of the AВ0- incompatibility mother and child are considered, namely A- and B-glycans, as well as the corresponding anti-glycan alloantibodies. Close attention is paid to the structure features of glycan alloantigens on the red blood cells of the fetus and adult. The possible correlation of the frequency and severity of HDN with the blood group of mother and child, as well as with the titer of maternal alloantibodies, has been considered. The influence of immunoglobulin G subclasses on the AB0-HDN development has been evaluated. In most cases, AB0-HDN appear when the mother has the blood group 0, and the fetus has the group A (subgroup A1) or the group B. Other rare incidences of AB0-incompatibility with severe course are occurred. As a whole the etiology of AB0-HDN is complex and the HDN severity is influenced by many factors. The authors have analyzed statistical data, as well as the prevalence of AB0-incompatibility and AB0-HDN in various regions of the world. Current approaches to the diagnosis of AB0-HDN are discussed in addition. By now the problems of AB0- HDN occurrence and developing of ways to overcome this disease remain relevant

Features of the immune response in children with acute respiratory infections caused by DNA and RNA viruses

The issues of immunopathogenesis of acute respiratory viral infections (ARVI) remain relevant, despite a long history of study. The aim of the study was to investigate the characteristics of the content of some cytokines in the blood serum of children with ARVI caused by DNA and RNA-containing viruses. Material and methods. We examined 92 children with ARVI at the age from 1 to 15 years, hospitalized in the hospital of the Children’s Clinical Hospital No. 6 (Novosibirsk). In order to determine the etiological factor, a study was carried out using the RT-PCR method (test systems AmpliSensORVI-screen-FL, “InterLabService”, Russia) of mucus from the nose and throat for the presence of genetic material of viruses that cause ARVI. Determination of the content of IL-8, IL-17, IFN-γ in the blood serum in children of all groups was carried out by the method of solid-phase ELISA using commercial test systems of LLC “Cytokin” (Russia). Results and discussion. 4 groups were formed: group I (n = 20) children with ARVI caused by DNA-containing viruses (group B, C, E adenoviruses, bocaviruses); group II (n = 53) children with ARVI caused by RNA viruses (RS virus, metapneumovirus, parainfluenza viruses 1, 2, 3, 4, rhinovirus and coronoviruses); group III (n = 12) children with ARVI caused by mixed infection; group IV (n = 7) – the genetic material of the pathogen has not been isolated. Concentration of IL-8, IL-17, IFN-γ was significantly increased in all groups compared to the normative values. Higher values of IFN-γ and IL-8 were revealed in patients with DNA viruses compared with the group with RNA-containing viruses, although the excess of IFN-γ was not statistically significant. Differences in the content of IFN-γ, IL-8 and IL-17 were noted for various etiological viral agents, but they were not significant. Conclusions. The results obtained can serve as confirmation that the functional characteristics of the response of the immune system in children with ARVI are determined not so much by the etiological factor as by its individual state. With ARVI in children, the presence of genetic material from more than one virus, apparently, is not a significant potentiating factor in the activation of the immune response. At the same time, a negative PCR result with a detailed clinical picture of ARVI does not exclude the viral genesis of the disease

ЛИТИЙ КАК ФАКТОР СОПРЯЖЕНИЯ НАРУШЕНИЙ МИНЕРАЛЬНОГО И УГЛЕВОДНОГО ГОМЕОСТАЗА ПРИ ЗЛОКАЧЕСТВЕННЫХ НОВООБРАЗОВАНИЯХ ЭПИТЕЛИАЛЬНЫХ ТКАНЕЙ

The impact of changes in orientation of the metabolism of carbohydrates and minerals in the cell malignancy has been demonstrated in several studies. The aim of this study was to analyze the molecular mechanisms and relationship of carbohydrate and mineral homeostasis with the processes of carcinogenesis. Parameters of carbohydrate and mineral metabolism of blood were defined in 73 patients with malignant tumors of epithelial tissues and 31 healthy subjects. In the presence of malignant tumors of epithelial tissues there was a statistically significant increase in the levels of glucose and glycated hemoglobin in the early stages of the disease and the absence of them at stage IV of the disease. There were no statistically significant differences in the levels of C-peptide and immunoreactive insulin in blood samples of cancer patients, although they tended to increase compared with the control group. Analysis of the composition of macroelements at the early stages of carcinogenesis revealed a statistically significant reduction of sodium level in plasma which wasn’t observed at the terminal stage of the disease. The concentrations of potassium and chlorine tend to increase in cancer patients, but the differences between these parameters were not statistically significant. Concentrations of calcium and magnesium significantly increased in the presence of malignant tumors. Analysis of microelements in the blood plasma showed a decrease in the concentration of cuprum and lithium (in 2.5-5 times) and the growth of strontium concentrations. Lithium has multiple effects on the life of cells, affecting a number of elements of messengers, as well as being the link between the carbohydrate metabolism and cell malignancy. Disorders of mineral homeostasis are important element in the disintegration of the metabolic processes in carcinogenesisВлияние изменения направленности метаболизма углеводов и минерального обмена на малигнизацию клеток было наглядно показано в ряде работ. Целью данного исследования стал анализ молекулярных механизмов взаимосвязи углеводного и минерального гомеостаза с процессами канцерогенеза. Определяли параметры углеводного и минерального обменов крови у 73 больных злокачественными новообразованиями эпителиальных тканей и 31 практически здоровых лиц. При злокачественных новообразованиях эпителиальных тканей выявлено статистически значимое повышение уровней глюкозы и гликилированного гемоглобина на начальных стадиях заболевания при отсутствии такового при IV стадии заболевания. Статистически значимых отличий по уровням С-пептида и иммунореактивного инсулина в крови онкологических больных выявлено не было, хотя и наблюдалась тенденция к их повышению по сравнению с контрольной группой. При анализе содержания макроэлементов уже на начальных стадиях канцерогенеза обнаружено статистически значимое снижение уровня Na в плазме крови, не наблюдающееся при терминальной стадии. Концентрации K и Сl имеет тенденцию к повышению у онкологических больных, но различия этих показателей статистически не значимы. При злокачественных новообразованиях значимо повышается содержание Ca, Р, Mg. Анализ уровня микроэлементов в плазме крови показал снижение концентрации Cu, Li (в 2,5–5 раз), рост содержания Sr. Литий оказывает множественные эффекты на жизнедеятельность клеток, влияя на ряд элементов систем мессенджеров, а также являясь сопрягающим звеном между углеводным обменом и малигнизацией клеток. Нарушение минерального гомеостаза является значимым звеном в дезинтеграции метаболических процессов при канцерогенезе.

Синдром VEXAS: на рубеже смены представлений об известных заболеваниях

This article presents the first case of VEXAS syndrome identified in the Russian Federation as well as characteristics of currently known clinical manifestations and treatment approaches. The clinical observation described is an impressive example of how the identification of a new pathogenic mutation can change the understanding of the classification, diagnosis and treatment of previously known immunoinflammatory diseases. Thus, in refractory forms of relapsing polychondritis, neutrophilic dermatosis, atypical forms of vasculitis, inflammatory joint diseases or undifferentiated systemic inflammatory syndrome, especially when associated with macrocytic anemia and myelodysplastic syndrome, VEXAS syndrome should be suspected and genetic testing should be performed to exclude the autoinflammatory nature of the existing condition.В статье приведен первый случай синдрома VEXAS, выявленный в Российской Федерации, а также характеристика известных на настоящий момент клинических проявлений и подходов к его терапии. Описанное клиническое наблюдение является ярким примером того, как выявление новой патогенной мутации может изменить представление о классификации, диагностике и терапии ранее известных иммуновоспалительных заболеваний. Так, при рефрактерных формах рецидивирующего полихондрита, нейтрофильного дерматоза, нетипичных формах васкулита, воспалительных заболеваний суставов или недифференцированном системном воспалительном синдроме, особенно при ассоциации с макроцитарной анемией и миелодиспластическим синдромом, необходима настороженность в отношении синдрома VEXAS и проведение генетического исследования для исключения аутовоспалительной природы имеющегося состояния

Comparison of printed glycan array, suspension array and ELISA in the detection of human anti-glycan antibodies

Anti-glycan antibodies represent a vast and yet insufficiently investigated subpopulation of naturally occurring and adaptive antibodies in humans. Recently, a variety of glycan-based microarrays emerged, allowing high-throughput profiling of a large repertoire of antibodies. As there are no direct approaches for comparison and evaluation of multi-glycan assays we compared three glycan-based immunoassays, namely printed glycan array (PGA), fluorescent microsphere-based suspension array (SA) and ELISA for their efficacy and selectivity in profiling anti-glycan antibodies in a cohort of 48 patients with and without ovarian cancer. The ABO blood group glycan antigens were selected as well recognized ligands for sensitivity and specificity assessments. As another ligand we selected P1, a member of the P blood group system recently identified by PGA as a potential ovarian cancer biomarker. All three glyco-immunoassays reflected the known ABO blood groups with high performance. In contrast, anti-P1 antibody binding profiles displayed much lower concordance. Whilst anti-P1 antibody levels between benign controls and ovarian cancer patients were significantly discriminated using PGA (p = 0.004), we got only similar results using SA (p = 0.03) but not for ELISA. Our findings demonstrate that whilst assays were largely positively correlated, each presents unique characteristic features and should be validated by an independent patient cohort rather than another array technique. The variety between methods presumably reflects the differences in glycan presentation and the antigen/antibody ratio, assay conditions and detection technique. This indicates that the glycan-antibody interaction of interest has to guide the assay selection

Изучение продукции некоторых цитокинов при вирусных инфекциях, протекающих с диарейным синдромом у детей

The aim of the study was to study the characteristics of the content of certain cytokines in serum as indicators of the immune response in viral infections accompanied by diarrhea syndrome in children. Materials and research methods. A survey was conducted of 92 children aged 3 months to 15 years with acute respiratory viral infections hospitalized in hospital No. 6 in Novosibirsk in the first 2 days from the onset of the disease. Two groups were formed — group 1 — patients with diarrheal syndrome and signs of respiratory system damage. Group 2 — children with isolated lesions of the respiratory tract. In all children, the genetic material of viruses was determined by polymerase chain reaction (PCR) in the nose and throat washes. Also, in all children, the determination of serum levels of IL-8, IL-17, IFN-ã by ELISA was performed. Results and discussion. When studying the levels of cytokines (IFN-ã, IL-8, IL-17) in patients with signs of gastrointestinal tract lesions in comparison with isolated respiratory manifestations, no statistically significant differences were found. However, when analyzing the levels of the studied parameters in patients with diarrheal syndrome in different age groups, significant differences in the levels of IFN-ã and IL-8 were revealed.Целью исследования явилось изучение особенностей содержания некоторых цитокинов в сыворотке крови как показателей иммунного реагирования при вирусных инфекциях, сопровождающихся диарейным синдромом у детей. Материалы и методы исследования. Проведено обследование 92 детей в возрасте от 3 месяцев до 15 лет с острыми респираторными вирусными инфекциями, госпитализированных в стационар ДКБ №6 города Новосибирска в первые двое суток от начала заболевания. Сформированы две группы: I группа — пациенты с диарейным синдромом и признаками поражения респираторной системы. Группа II — дети с изолированным поражением респираторного тракта. У всех детей провели определение генетического материала вирусов методом полимеразной цепной реакции (ПЦР) в смывах из носо- и ротоглотки. Также у всех детей было проведено определение содержания в сыворотке крови IL-8, IL-17, IFN-ã методом ИФА. Результаты и обсуждение. При исследовании уровней содержания цитокинов (IFN-ã, IL-8, IL-17) у пациентов с признаками поражения желудочно-кишечного тракта в сравнении с изолированными респираторными проявлениями статистически значимых различий выявлено не было. Однако при анализе уровней исследуемых показателей у пациентов с диарейным синдромом в различных возрастных группах выявлены достоверные различия в уровне содержания IFN-ã и IL-8
