"West"-"East" in the tatar national literature

Determining actuality and prospects of system analysis and comparing Western European and Arab - Persian prose translated and adapted into Tatar language in the period of the end of XIX- the beginning of XX centuries, summarize and identify the influence the Tatar national literature in the context of " West"-"East". It should be made the analysis and to define degree of similarity some originals with their versions in Tatar in genre aspects, architectonics and poetics of a literary text, to show the important of literary narration both in the theoretical and historic-literary scale. It is also necessary to reveal peculiarities of translation poetics, especially using of translated lexica-semantic, stylistic units. © IDOSI Publications, 2014

In the context of globalization penetrating conceptual spheres of society problems of regional and minority languages, functional development need to be harmonized with historically existing linguistic phenomena and contemporary political, socio-cultural and linguistic realities. According to most scientists, the federation emerges if, on the one hand, there exists linguistic, cultural and ethnic variety and, on the other hand, if there is a need for national integrity

Stretch Activated Channels in Proprioceptive Organs of Crab and Crayfish Are Sensitive to Gadolinium but not Amiloride, Ruthenium Red or Low pH

The type of stretch activated receptors (SARs) in the chordotonal organs in the crab walking leg and of the muscle receptor organ (MRO) in the crayfish abdomen have not yet been classified as to their molecular or pharmacological profile. The purpose of this study is to examine the pharmacological profile of SARs in the proprioceptive neurons in the crab and crayfish models. Since many SARs share the pharmacological profile of displaying low pH or being proton sensitive (i.e. being more active) or blocked by the diuretic amiloride or ruthenium red as well as being blocked by the broad stretch activated channel blocker gadolinium (Gd3+), we used these agents to screen the receptors. Various displacement rates as well as static positions that activate the stretch activated receptors were used in examining their pharmacological profiles. Hour-long exposure to low pH decreased neural activity of the chordotonal organ of the crab more so than to amiloride or ruthenium red. The crayfish MRO did not show pH sensitivity or sensitivity to amiloride or ruthenium red. Gd3+ rapidly blocked neural activity in both the crab and crayfish. It appears these stretch activated receptors may not have a classification that is suited to the standard pharmacological profiles. The molecular makeup of the channels also awaits characterization. This could reveal a novel SAR subtype. Our neurophysiology course1 took this project on as a course-based undergraduate research experience (CURE) to address an authentic research question

The Effect of CO\u3csub\u3e2\u3c/sub\u3e, Intracellular pH and Extracellular pH on Mechanosensory Proprioceptor Responses in Crayfish and Crab

Proprioceptive neurons monitor the movements of limbs and joints to transduce the movements into electrical signals. These neurons function similarly in species from arthropods to humans. These neurons can be compromised in disease states and in adverse environmental conditions such as with changes in external and internal pH. We used two model preparations (the crayfish muscle receptor organ and a chordotonal organ in the limb of a crab) to characterize the responses of these proprioceptors to external and internal pH changes as well as raised CO2. The results demonstrate the proprioceptive organs are not highly sensitive to changes in extracellular pH, when reduced to 5.0 from 7.4. However, if intracellular pH is decreased by exposure to propionic acid or saline containing CO2, there is a rapid decrease in firing rate in response to joint movements. The responses recover quickly upon reintroduction of normal pH (7.4) or saline not tainted with CO2. These basic understandings may help to address the mechanistic properties of mechanosensitive receptors in other organisms, such as muscle spindles in skeletal muscles of mammals and tactile as well as pressure (i.e., blood pressure) sensory receptors

Polygenic burden in focal and generalized epilepsies.

Rare genetic variants can cause epilepsy, and genetic testing has been widely adopted for severe, paediatric-onset epilepsies. The phenotypic consequences of common genetic risk burden for epilepsies and their potential future clinical applications have not yet been determined. Using polygenic risk scores (PRS) from a European-ancestry genome-wide association study in generalized and focal epilepsy, we quantified common genetic burden in patients with generalized epilepsy (GE-PRS) or focal epilepsy (FE-PRS) from two independent non-Finnish European cohorts (Epi25 Consortium, n = 5705; Cleveland Clinic Epilepsy Center, n = 620; both compared to 20 435 controls). One Finnish-ancestry population isolate (Finnish-ancestry Epi25, n = 449; compared to 1559 controls), two European-ancestry biobanks (UK Biobank, n = 383 656; Vanderbilt biorepository, n = 49 494), and one Japanese-ancestry biobank (BioBank Japan, n = 168 680) were used for additional replications. Across 8386 patients with epilepsy and 622 212 population controls, we found and replicated significantly higher GE-PRS in patients with generalized epilepsy of European-ancestry compared to patients with focal epilepsy (Epi25: P = 1.64×10-15; Cleveland: P = 2.85×10-4; Finnish-ancestry Epi25: P = 1.80×10-4) or population controls (Epi25: P = 2.35×10-70; Cleveland: P = 1.43×10-7; Finnish-ancestry Epi25: P = 3.11×10-4; UK Biobank and Vanderbilt biorepository meta-analysis: P = 7.99×10-4). FE-PRS were significantly higher in patients with focal epilepsy compared to controls in the non-Finnish, non-biobank cohorts (Epi25: P = 5.74×10-19; Cleveland: P = 1.69×10-6). European ancestry-derived PRS did not predict generalized epilepsy or focal epilepsy in Japanese-ancestry individuals. Finally, we observed a significant 4.6-fold and a 4.5-fold enrichment of patients with generalized epilepsy compared to controls in the top 0.5% highest GE-PRS of the two non-Finnish European cohorts (Epi25: P = 2.60×10-15; Cleveland: P = 1.39×10-2). We conclude that common variant risk associated with epilepsy is significantly enriched in multiple cohorts of patients with epilepsy compared to controls-in particular for generalized epilepsy. As sample sizes and PRS accuracy continue to increase with further common variant discovery, PRS could complement established clinical biomarkers and augment genetic testing for patient classification, comorbidity research, and potentially targeted treatment

THE MAIN PARAMETERS OF CELLULAR IMMUNITY IN PATIENTS WITH TRIPLE-NEGATIVE BREAST CANCER: RELATIONSHIP WITH EFFICIENCY OF CHEMOTHERAPY

Chemotherapy is among the primary methods of treating advanced breast cancer. It was shown that clinical efficacy of various chemotherapeutic agents in many cases depends not only on their direct cytostatic and/or cytotoxic effect upon tumor cells, but also on their ability to modulate phenotype of the tumor cells and to influence anti-tumor immune response. Initial state of the immune system and its response to treatment is crucial. Antitumor response involves cells of innate and adaptive immunity (NK, NKT, T cells). These populations are heterogeneous and contain, e.g., cells with antitumor activity and regulatory (suppressor) cells that suppress immune response and promote tumor progression. The aim of this work was to determine the relationship between the initial state of cellular immunity of patients suffering from locally advanced breast cancer with triple negative phenotype, and clinical effect of chemotherapy (cisplatin + doxorubicin/paclitaxel), and studying effects of the therapy upon subpopulation profiles of peripheral blood lymphocytes in the patients. We registered the terms of the disease progression as well as overall survival and progression-free survival. The disease progressed in 25 of 53 cases (47.2%) whereas 28 of 53 patients (52.8%) remained progression-free. The observation period was 35.5 months. Laboratory examination of the patients included immunophenotyping of peripheral blood lymphocytes and determination of NK cell cytotoxic activity before and after chemotherapy. Percentages of effectors and regulatory lymphocyte populations were determined. The results obtained showed that, for some lymphocyte subsets, the pre-treatment differences of cell percentage deviations from control were found between the progression-free groups and patients with progression of the disease. The differences in percentages of NKT cells and lymphocytes expressing CD25 activation marker proved to be most significant. Decreased number of NKT cells and activated CD25+ lymphocytes prior to chemotherapy was associated with increased probability of disease progression. Reduced percentage of NKT cells against control was observed in 56% of patients from the progression group (PD), and only 21.4% in the group free of disease progression (DF). [OR = 4.6 (95% CI 1.4 to 15.4)]. Percentage of CD25+ lymphocytes was decreased from 68.2% in the PD group, and 28.6% for DF patients [OR = 5.4 (95% CI 1.6-18.1)]. We studied relationships between the overall survival (OS) and percentage of perforin-containing NK, NKT, and T cells, and mean perforin fluorescence density (PFD) in these lymphocyte subsets in 26 of the 53 patients before treatment. A statistically significant positive correlation was revealed between OS and perforin PFD in all the three cell populations under study. Normalization of the parameters altered before treatment, and an increase of T cell numbers was observed in the disease-free patients

Genome-wide analysis in over 1 million individuals of European ancestry yields improved polygenic risk scores for blood pressure traits

Hypertension affects more than one billion people worldwide. Here we identify 113 novel loci, reporting a total of 2,103 independent genetic signals (P < 5 × 10−8) from the largest single-stage blood pressure (BP) genome-wide association study to date (n = 1,028,980 European individuals). These associations explain more than 60% of single nucleotide polymorphism-based BP heritability. Comparing top versus bottom deciles of polygenic risk scores (PRSs) reveals clinically meaningful differences in BP (16.9 mmHg systolic BP, 95% CI, 15.5–18.2 mmHg, P = 2.22 × 10−126) and more than a sevenfold higher odds of hypertension risk (odds ratio, 7.33; 95% CI, 5.54–9.70; P = 4.13 × 10−44) in an independent dataset. Adding PRS into hypertension-prediction models increased the area under the receiver operating characteristic curve (AUROC) from 0.791 (95% CI, 0.781–0.801) to 0.826 (95% CI, 0.817–0.836, ∆AUROC, 0.035, P = 1.98 × 10−34). We compare the 2,103 loci results in non-European ancestries and show significant PRS associations in a large African-American sample. Secondary analyses implicate 500 genes previously unreported for BP. Our study highlights the role of increasingly large genomic studies for precision health research
