Features of immunological status in young children, with spastic forms of infantile cerebral paralysis

In order to analyze the prognostic significance of the clinical and immunologic indices of central nervous system (CNS) lesions of the perinatal period, 135 children with an early residual stage of infantile cerebral paralysis (cerebral paralysis) were examined. A statistically significant increase in functional phagocytic activity, tumor necrosis factor-α (TNF-α) level in blood serum and oral fluid (p≤0.01 and p<0.05, respectively) in children with periventricular leukomalacia in spastic forms of infantile cerebral paralysis. Neuroimmunological parameters of blood serum and oral fluid can be used as criteria for diagnosing the severity of structural and morphological changes in the central nervous system and predicting cerebral disorders in children with an outcome in infantile cerebral paralysis

INDOL-3-CARBINOL IN THE TREATMENT OF BENIGN BREAST DISORDERS

123 patients with various forms of fibrocystic mastopathy (n=114) and fibroadenoma of mammry gland (n=9) were enrolled into the study. Indol-3-carbinol (indinol, Close corporation «Mirax-Pharma») was administered in the dose of 300—400 mg per day for 3—6 months. Disappearance of complaints to pain was observed in 35% of patients after 3 months of therapy and in 63% — after 6 months of therapy. Objective signs of fibrocystic mastopathy completely regressed in 9% of patients after 3 months of therapy and in 16% — after 6 month of therapy. Overall considerable improvement of condition or complete cure was seen in 55% of patients after 3 month of treatment and in 92% — after 6 months of therapy. Thus, indinol is highly effective and safe agent for treatment of different types of mastopathy

BaCe0.5Zr0.3Y0.2–xYbxO3–δ proton-conducting electrolytes for intermediate-temperature solid oxide fuel cells

This work describes new findings concerning the preparation of Y- and Yb- co-doped BaCeO3–BaZrO3 materials, their structural, microstructural, electrical characterization and application as electrolytes for solid oxide fuel cell. The BaCe0.5Zr0.3Y0.2–xYbxO3–δ (x = 0–0.2, Δx = 0.05) materials are successfully synthesized using a citrate-nitrate combustion method and then sintered at 1450 °C to form single-phase and highly dense ceramic samples. The sample with the BaCe0.5Zr0.3Y0.1Yb0.1O3–δ (BCZYYb) composition is found to possess the largest grains coupled with the highest ionic conductivity. This ceramic material is used as an electrolyte for the fabrication an electrochemical cell designed as NiO–BCZYYb|BCZYYb (25 μm)|NBFC (where NBFC = Nd0.5Ba0.5Fe1.9Cu0.1O3–δ), which demonstrates as maximal power density as 140 and 290 mW cm−2 at 600 and 700 °C with open circuit voltages higher than 1.01–1.04 V, respectively. The separation of the total resistance of the cell in its ohmic and polarization components allows the film electrolyte conductivity to be calculated, which attains quite high level (2.4 and 3.8 mS cm−1, respectively). This study shows that BaCe0.5Zr0.3Y0.1Yb0.1O3–δ can be used instead of electrolytes with a lower Zr-concentration (for example, BaCe0.7Zr0.1Y0.1Yb0.1O3–δ) with no significant deterioration of the transport properties. © 2017 Elsevier Lt

Effect of isovalent substitution of La3+ in Ca-doped LaNbO4 on the thermal and electrical properties

The effect of the equimolar substitution of lanthanum in Ca-doped LaNbO4 on the functionality of (La0.5Ln0.5)0.99Сa0.01NbO4–δ (where Ln = La, Nd and Sm) is investigated in the present work. Highly dense, single-phase and of microstructurally quality ceramic samples are synthesized, using a solid state reaction method. The relation between Ln3+ ionic radii with thermal and electrical properties is successfully revealed. It is found that the partial substitution with other lanthanides can be considered as a promising tool to suppress thermal expansion differences between low- and high-temperature modifications of lanthanum niobates; however, at the same time, the ionic conductivity decreases, which requires searching the trade-off for the optimal composition identification. © 2018 Elsevier Ltd and Techna Group S.r.l

Application of hyperspectral and multispectral datasets for mineral mapping

In this study, hyperspectral datasets are simulated from multispectral data using a spectral reconstruction approach which is a sensor-independent technique. This technique makes use of information from atmospherically corrected multispectral Remote Sensing (MRS) data and normalized ground spectra for the simulation of HRS data. In this study EO-1, the ALI dataset was used for the simulation of hyperspectral Remote Sensing (HRS) data to discover the Udaipur region’s unique minerals. A total of 61 spectral bands with 10 nm bandwidth were simulated. The simulated HRS data were validated using visual interpretation, statistical and classification approaches. Simulated HRS data from EO-1 Advanced Land Imager (ALI) has shown a high correlation with EO-1 Hyperion data. Spectral Angle Mapper (SAM) classification was also performed on simulated hyperspectral data for mineral mapping. It was observed that simulated hyperspectral data have shown comparable results with Hyperion and are better than their corresponding multispectral datasets

Surface displacement detection using object-based image analysis, Tashkent region, Uzbekistan

Landslides can be listed as a major natural hazard for the Bostanlik district, Uzbekistan characterized by its mountain terrain. Currently, a monitoring system is not in place, which can mitigate the numerous negative effects of landslides. The current study presents the first Earth Observation-based landslide inventory for Uzbekistan. We applied a random forest Object-Based Image Analysis (OBIA) on very high-resolution GeoEye-1 Earth observation data to detect surface displacement. While performing 10-fold cross-validation to assess the classification accuracy. Our results indicate very high overall accuracy (0.93) and user’s (0.87) and producer’s (0.91) accuracy for the surface displacement class. We determined that 5.5% of the study area was classified as surface displacement. The obtained results are highly valuable for local authorities for the management of landslides, hazard prevention, and land use planning

LEAF RUST RESISTANCE IN COMMON WHEAT VARIETIES AND LINES FROM THE COLLECTION OF THE VAVILOV PLANT INDUSTRY INSTITUTE CARRYING ALIEN GENETIC MATERIAL

Leaf rust resistance was estimated in 83 common wheat accessions from the collection of the Vavilov Institute carrying alien genetic material. Eight accessions with seedling resistance and 27 accessions with adult plant resistance were found. Analysis with molecular markers revealed genes highly and moderately efficient in Russia – Lr24, Lr39, Lr21, and Lr37 – and a rye translocation 1AL.1RS. The samples accessions effective Lr genes are promising donors in Russian breeding programs. Lines raised with the use of T. timopheevii were heterogeneous for resistance. No molecular markers of the Lr50 gene known for this species were detected there. These lines demand further examination and selection
