[Herpesviruses in patients after renal transplantation].

Aim: To estimate graft function after kidney transplantation during active herpesviruses or superinfection Materials and methods. The study included 32 patients (men 21, women 11) with end-stage chronic kidney disease. The median age was 43 years.

Partitioning of REE between calcite and carbonatitic melt containing P, S, Si at 650-900 °C and 100 MPa.

Carbonatites host some unique ore deposits, especially REE, and fractional crystallization might be a potentially powerful mechanism for control enrichment of carbonatitic magmas by these metals to economically significant levels. At present, data on distribution coefficients of REE during fractional crystallization of carbonatitic melts at volcanic conditions are extremely scarce. Here we present an experimental study of REE partitioning between carbonatitic melts and calcite in the system CaCO-NaCO with varying amounts of PO, F, Cl, SiO, SO at 650-900 °C and 100 MPa using cold-seal pressure vessels and LA-ICP-MS.

[Repeated haploidentical allogeneic hematopoietic stem cell transplantation with TCR αβ/CD19 depletion in patient with primary myelofibrosis. Case report].

Indications of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with primary myelofibrosis are intermediate-2 and high-risk group of DIPSS (Dynamic International Prognostic Scoring System), beginning of the disease in childhood. The other adverse factors affect engraftment and survival after allo-HSCT, example partialy matched donor. But the result of allo-HSCT from matched related donors and result of allo-HSCT from haploidentical donors are comparable.

[The prognostic value of ASXL1 mutation in primary myelofibrosis. Literature review and clinical case description].

Primary myelofibrosis is a myeloproliferative neoplasm that occurs de novo, characterized by clonal proliferation of stem cells, abnormal expression of cytokines, bone marrow fibrosis, hepatosplenomegaly as a result of extramedullary hematopoiesis, symptoms of tumor intoxication, cachexemia, peripheral blood leukoerythroblastosis, leukemic progression and low survival. Primary myelofibrosis is a chronic incurable disease. The aims of therapy: preventing progression, increasing overall survival, improving quality of life.

Gray-zone lymphoma. Examples of rare clinical manifestation.

Mediastinal gray-zone lymphoma (MGZL, lymphoma with features intermediate between classical Hodgkin lymphoma and diffuse large B-cell lymphoma) was declared as a separate entity in WHO classification of Tumors of Haematopoetic and Lymphoid Tissues in 2008 and 2017 years. Despite of similar pathomorphological characteristics between primary mediastinal B-cell lymphoma and Hodgkin lymphoma, clinical features and optimal therapeutic approach to MGZL are not clearly defined. Usually MGZL manifests with mediastinal lymphadenopathy, although extranodal lesions often occur (grey-zone lymphoma, GZL).

[Termination of Replication and Mechanisms of Heteroplasmy in Sturgeon Mitochondrial DNA].

The control region of mitochondrial DNA (mtDNA) in sturgeon contains one to seven tandem nucleotide repeats 78-83 bp in size. Some sturgeon species are homoplasmic by the D-loop size (Acipenser nudiventris, A. oxyrinchus, A.

[Features of redox processes in the amniotic fluid at placental insufficiency].

Activity of prooxidant enzymes (NADPH-oxidase and xanthine oxidase), antioxidant enzymes (superoxide dismutase (SOD) and catalase), enzymes of the glutathione-dependent systems, as well as antioxidant vitamins (retinol and a-tocopherol), lipid peroxidation products (LPP) (conjugated dienes and Schiff bases), and peroxide chemiluminescence were studied in the amniotic fluid at different periods of physiological pregnancy and placental insufficiency (PI). It was found that at PI the activity of NADPH-oxidase, xanthine oxidase increased and the activity of SOD, catalase, glutathione peroxidase, glutathione reductase, glutathione transferase and the content of fat-soluble vitamins decreased. The direct and inverse correlation between the studied pro- and antioxidant parameters and the content of LPP products, was found ro be different in the II and III trimesters of gestation.

MicroRNA-Dependent Regulation of IGF1R Gene Expression in Hormone-Sensitive and Hormone-Resistant Prostate Cancer Cells.

Using multiple parallel sequencing on Illumina platform, we identified eight microRNAs that showed significant opposite changes of gene expression in cells of the hormone-sensitive LNCaP prostate cancer cell line and in cells of the hormone-resistant DU-145 cell line, in comparison to the microRNA expression in the normal prostate tissue cells. We found that the insulin-like growth factor 1 receptor (IGF1R) gene is a target of five microRNAs whose expression is increased in LNCaP cells and reduced in DU-145 cells.

Differential Evolution approach to detect recent admixture.

The genetic structure of human populations is extraordinarily complex and of fundamental importance to studies of anthropology, evolution, and medicine. As increasingly many individuals are of mixed origin, there is an unmet need for tools that can infer multiple origins. Misclassification of such individuals can lead to incorrect and costly misinterpretations of genomic data, primarily in disease studies and drug trials.

Geographic population structure analysis of worldwide human populations infers their biogeographical origins.

The search for a method that utilizes biological information to predict humans' place of origin has occupied scientists for millennia. Over the past four decades, scientists have employed genetic data in an effort to achieve this goal but with limited success. While biogeographical algorithms using next-generation sequencing data have achieved an accuracy of 700 km in Europe, they were inaccurate elsewhere.

[Comparative assessment of dot-immunoassay and immunochromatography methods for detection of 01 serogroup of vibrio cholerae].

Aim: Comparative study of sensitivity and specificity of immunochromatographic (IC) assay kit and dot-immunoanalysis for assessment of feasibility of their use for laboratory diagnostics of cholera.

Materials And Methods: Experimental lots of IC assay kit and dot-immunoassay (DIA) for detection of Vibrio cholerae serogroup 01 serovars Ogava and Inaba were constructed on the basis of species-specific monoclonal antibodies (MCA) conjugated with colloid gold (IC) and peroxidase (DIA). Hybridoma-producer of MCAwas obtained and stored in liquid nitrogen in Rostov-on-Don Research Institute for Plague Control.

Genes for hybrid uridine phosphorylases (UPases) consisting of fragments of amino acid sequences of UPases from Escherichia coli and Salmonella typhimurium were constructed. Producing strains of the corresponding proteins were genetically engineered. Mutant forms of the E.

[Geriatrics--an important field of clinical medicine].

The topical aspects of geriatrics, which is believed to be an important part of clinical medicine, are overviewed. The age-specific features of therapeutic actions in elderly and senile patients are delineated. A special emphasis is given to the rehabilitation measures which are to be taken on a person's retirement, as well as to the significance of the motor activity and rational nutrition in the prevention of early aging.

The state of the renin-angiotensin-aldosterone system in various clinical forms of hypertension in aging.

The authors' data give evidence for an early involvement of the renin-angiotensin-aldosterone system in the hypertension pathogenesis with aging. The elderly patients with the systolic hypertension variant showed marked hyporeninemia and hyperaldosteronemia, while those with the systolic-diastolic variant displayed an increased or normal plasma renin activity against moderately increased aldosterone concentration. There was a marked increase of plasma renin activity in the patients with the cardiac form and a high circulating aldosterone concentration with the cerebral form of hypertension.
