    This study investigated the level of conceptual and metacognitive abilities and their interaction in adolescents with different forms of dysontogenesis. The total sample (N= 173) included four groups of young adolescents (11-12 years old): with normal development, with infantile cerebral palsy (CP), with attention deficit hyperactivity disorder (ADHD), and with delayed intellectual development (DID). We measured the adolescents’ performance on tests of conceptual abilities (the use of categories at different grades of generalization, the discovery of abstract meaning and implicit connections between concepts) and metacognitive abilities (attention selectivity, as measured by Mtinsterberg’s test and the understanding of hidden pictures, and attention organization, as measured by indices of cognitive styles). The results showed, first, that in comparison with normal adolescents, the adolescents with CP and ADHD had a deficit of metacognitive abilities, but they did not differ in rates of conceptual abilities. As for adolescents with DID, even though they had lower rates of conceptual abilities and attention selectivity, they did not differ from the β€œnorm” group on some indices of attention organization. Second, a tendency for the disintegration of conceptual and metacognitive abilities (as measured by correlation and factor analysis) was most clearly seen in the adolescents with ADHD and DID. The adolescents with CP and ADHD had conceptual (categorial and generative) abilities as a mental resource, and the adolescents with DID had metacognitive abilities as a mental resource. The resource function of conceptual and metacognitive abilities was determined not only by their level but also by the extent of their interaction (integration)

    Aim: to analyze leptin and adiponectin serum levels inΒ patients with chronic hepatitis C in comparison with metabolicΒ syndrome components, biochemical features and stageΒ of hepatitis.Materials and methods: In 93 patients with chronic HCVΒ in age 20-55 with a few symptomatic HCV-infection andΒ minimal liver fibrosis stage serum leptin and adiponectinΒ was measured. Associations between leptin, adiponectin andΒ metabolic abnormalities, biochemical features, and hepaticΒ fibrosis were determined.Results: Abdominal obesity was revealed at 40% patients,Β overweight – at 41%, insulin resistance – at 36,6%Β cases. The leptin and adiponectin levels were within normalΒ limits range at most patients. Patients with minimal liver fibrosisΒ had higher index of leptin by comparison to patientsΒ with moderate and severe fibrosis (r= – 0,402, Ρ€= 0,018). InΒ patients with HCV genotype 3a the adiponectin level was below,Β than in HCV genotype 1b. Patients with abdominal obesityΒ and overweight had higher leptin and lower adiponectinΒ indexes by comparison to patients without these metabolicΒ abnormalities. Direct cross-correlation between the leptinΒ level and body mass index (r=0,358, p=0,001), waist circumferenceΒ (r=0,292, p=0,01); negative cross-correlation betweenΒ the adiponectin level and body mass index (r=- 0,435,Β Ρ€ <0,021), waist circumference (r=- 0,386, Ρ€ =0,001) wereΒ displayed.Conclusion: Leptin and adiponectin blood levels in HCVpatientis associated with abdominal obesity and overweight.Β The connection of leptin level and liver fibrosis stage was revealed.Β Difference of adiponectin level in HCV-patients withΒ 3a and 1b genotypes of virus was found.ЦСль: ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ содСрТаниС Π»Π΅ΠΏΡ‚ΠΈΠ½Π° ΠΈ Π°Π΄ΠΈΠΏΠΎΠ½Π΅ΠΊΡ‚ΠΈΠ½Π° Π²Β ΠΊΡ€ΠΎΠ²ΠΈ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… хроничСским Π³Π΅ΠΏΠ°Ρ‚ΠΈΡ‚ΠΎΠΌ Π‘ Π² сопоставлСнии с ΠΊΠΎΠΌΠΏΠΎΠ½Π΅Π½Ρ‚Π°ΠΌΠΈ мСтаболичСского синдрома, биохимичСскими характСристиками ΠΈ стадиСй Ρ„ΠΈΠ±Ρ€ΠΎΠ·Π° ΠΏΠ΅Ρ‡Π΅Π½ΠΈ.Β ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.

    Chronic immune activation is one of the main causes of HIV disease progression. Bacterial components passed to the bloodstream from the gut as a result of microbial translocation, are known to induce immune activation. Component of Gram-negative bacteria’s cell walls, the lipopolysaccharide (LPS), is considered to be the major marker of microbial translocation. Through the activation of myeloid cells (predominantly monocytes) LPS causes the secretion of soluble CD14, thus making it a marker of LPS bioactivity. Besides sCD14 was shown to correlate with immune status in HIVinfected patients and to be an independent predictor of disease progression.Hypothesis: opiates increase microbial translocation from the gut in HIV-infected patients that is manifested by a higher concentration of sCD14 in plasma.Aim: to estimate the influence of opiate use on the level of sCD14 in plasma of HIV-infected patients.Materials and methods. Longitudinal study of 351 HIV positive individuals. Concentration of sCD14, was evaluated at 3 time points: baseline, after 12 and 24 months. Following groups were studied: 1) current opiate users – opiate use within past 30 days; 2) opiate users, who denied consumption of opiates within past 30 days; 3) people claiming to never have used opiates.Results. In dynamic assessment sCD14 mean was significantly higher in current opiate users (2222,46Β±39,02 ng/ml) against patients who denied opiates within past 30 days (1930Β±597 ng/ml) and those, claiming to never have used opiates (1915Β±577 ng/ml) (p<0,001).Conclusion. Opiate use in the course of HIV disease leads to increase in LPS induced monocyte activation which therefore signifies more intensive microbial translocation.Π₯роничСская активация ΠΈΠΌΠΌΡƒΠ½Π½ΠΎΠΉ систСмы являСтся ΠΎΠ΄Π½ΠΈΠΌ ΠΈΠ· основных Ρ„Π°ΠΊΡ‚ΠΎΡ€ΠΎΠ² ΠΏΠ°Ρ‚ΠΎΠ³Π΅Π½Π΅Π·Π° Π’Π˜Π§-ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΈ.

    No full text
    A pulsed plasmochemical method was used to obtain carbon-containing nanocomposites based on silicon oxide modified with titanium dioxide. The material contained a SixCyOz carrier with an average size of 50–150 nm and a shell of fine particles with an average size of 5–10 nm. The phase composition and morphology of the synthesized composites was studied by X-ray diffraction and transmission electron microscopy. The optical and photocatalytic properties of the nanoparticles from the carbon-based composite based on silicon oxide encapsulated in titanium dioxide were studied. The synthesized composite showed a high photocatalytic activity due to the decomposition of methylene blue under the influence of visible light in the wavelength range of 460–630 nm

    The aim of the publication is to demonstrate the implementation results of the β€œMathematics, Psychology, Intellect” (MPI) educational project used for selecting and devising the new textbook content for multipurpose learning activities and students’ intellect development in comprehensive schools. The methodology, based on the psycho-didactic approach, involves the analysis of the existing experience of textbooks development, including the traditional reference and narrative books, and the ones, organized as a dialogue with a student-reader and oriented toward the facts comprehension and reasoning. In the context of the reader-oriented theory, the author proves the advantages of special developmental materials complying with the enrichment model. Research results describe mathematical textbooks and learning materials development for secondary schools including students’ books, practicum and workbooks for independent study, and computer software for the 5 to 9th -year students. Secondly, the authors denote the psycho-didactic typology of and requirements for developmental texts. Scientific novelty is related to the specificity of the given academic texts, conveying the structure of the formal mathematical knowledge on the one hand, and on the other hand - developing the basic components of students’ mental experience (including cognitive, conceptual, metacognitive and intentional ones), and creating the conditions for exercising the individual cognitive styles. Practical significance results from activating the individual intellectual resources of school leavers, developing their learning ability and readiness for the future innovative professional and personal lifeЦСль ΠΏΡƒΠ±Π»ΠΈΠΊΠ°Ρ†ΠΈΠΈ – ΠΏΠΎΠ·Π½Π°ΠΊΠΎΠΌΠΈΡ‚ΡŒ Ρ‡ΠΈΡ‚Π°Ρ‚Π΅Π»Π΅ΠΉ с Π½Π΅ΠΊΠΎΡ‚ΠΎΡ€Ρ‹ΠΌΠΈ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Π°ΠΌΠΈ Ρ€Π΅Π°Π»ΠΈΠ·Π°Ρ†ΠΈΠΈ ΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Ρ‚Π΅Π»ΡŒΠ½ΠΎΠ³ΠΎ ΠΏΡ€ΠΎΠ΅ΠΊΡ‚Π° "ΠœΠ°Ρ‚Π΅ΠΌΠ°Ρ‚ΠΈΠΊΠ°.

    Aim: to analyze leptin and adiponectin serum levels inΒ patients with chronic hepatitis C in comparison with metabolicΒ syndrome components, biochemical features and stageΒ of hepatitis.Materials and methods: In 93 patients with chronic HCVΒ in age 20-55 with a few symptomatic HCV-infection andΒ minimal liver fibrosis stage serum leptin and adiponectinΒ was measured. Associations between leptin, adiponectin andΒ metabolic abnormalities, biochemical features, and hepaticΒ fibrosis were determined.Results: Abdominal obesity was revealed at 40% patients,Β overweight – at 41%, insulin resistance – at 36,6%Β cases. The leptin and adiponectin levels were within normalΒ limits range at most patients. Patients with minimal liver fibrosisΒ had higher index of leptin by comparison to patientsΒ with moderate and severe fibrosis (r= – 0,402, Ρ€= 0,018). InΒ patients with HCV genotype 3a the adiponectin level was below,Β than in HCV genotype 1b. Patients with abdominal obesityΒ and overweight had higher leptin and lower adiponectinΒ indexes by comparison to patients without these metabolicΒ abnormalities. Direct cross-correlation between the leptinΒ level and body mass index (r=0,358, p=0,001), waist circumferenceΒ (r=0,292, p=0,01); negative cross-correlation betweenΒ the adiponectin level and body mass index (r=- 0,435,Β Ρ€ <0,021), waist circumference (r=- 0,386, Ρ€ =0,001) wereΒ displayed.Conclusion: Leptin and adiponectin blood levels in HCVpatientis associated with abdominal obesity and overweight.Β The connection of leptin level and liver fibrosis stage was revealed.Β Difference of adiponectin level in HCV-patients withΒ 3a and 1b genotypes of virus was found

    LEVELS OF PLASMA SOLUBLE CD14 IN HIV-INFECTED OPIATE USERS

    Chronic immune activation is one of the main causes of HIV disease progression. Bacterial components passed to the bloodstream from the gut as a result of microbial translocation, are known to induce immune activation. Component of Gram-negative bacteria’s cell walls, the lipopolysaccharide (LPS), is considered to be the major marker of microbial translocation. Through the activation of myeloid cells (predominantly monocytes) LPS causes the secretion of soluble CD14, thus making it a marker of LPS bioactivity. Besides sCD14 was shown to correlate with immune status in HIVinfected patients and to be an independent predictor of disease progression.Hypothesis: opiates increase microbial translocation from the gut in HIV-infected patients that is manifested by a higher concentration of sCD14 in plasma.Aim: to estimate the influence of opiate use on the level of sCD14 in plasma of HIV-infected patients.Materials and methods. Longitudinal study of 351 HIV positive individuals. Concentration of sCD14, was evaluated at 3 time points: baseline, after 12 and 24 months. Following groups were studied: 1) current opiate users – opiate use within past 30 days; 2) opiate users, who denied consumption of opiates within past 30 days; 3) people claiming to never have used opiates.Results. In dynamic assessment sCD14 mean was significantly higher in current opiate users (2222,46Β±39,02 ng/ml) against patients who denied opiates within past 30 days (1930Β±597 ng/ml) and those, claiming to never have used opiates (1915Β±577 ng/ml) (p<0,001).Conclusion. Opiate use in the course of HIV disease leads to increase in LPS induced monocyte activation which therefore signifies more intensive microbial translocation

    Investigation of the influence of the energy conditions of pulsed plasma-chemical synthesis on the morphological and structural properties of copper-containing silica-based nanocomposites

    No full text
    This paper presents the results of a study of the effect of energy conditions (additional heating of the walls of the reaction chamber and subsequent action of an electron beam on the synthesized powder) of pulsed plasma-chemical synthesis on the morphology, average geometric size, phase and chemical composition of copper-containing silica-based nanocomposites. The nanocomposites were synthesized using a TEA-500 pulsed electron accelerator. It was the first time that copper-containing silica-based nanocomposites had been prepared using the pulsed plasma-chemical synthesis. The values of the band gap for the as-prepared nanocomposites were calculated. The nanocomposites were characterized by means of transmission electron microscopy and X-ray diffraction. The analysis revealed the changes in the morphology and phase composition of the nanocomposites upon energy conditions

    In this work, the TiO2@TixCyOz nanocomposite was obtained by adding a buffer gas to the initial mixture of reagents by the pulsed plasma-chemical method. Argon was used as a buffer gas. Pulsed plasma-chemical synthesis was realized using a TEA-500 electron accelerator. The physicochemical properties of the obtained TiO2@TixCyOz nanocomposites (morphology, average particle size, elemental, and phase composition) were studied. It was shown that by changing the buffer gas concentration, it was possible to control the phase composition, particle size, and shell thickness of TiO2@TixCyOz nanocomposites. The values of the band gap were calculated for the synthesized TiO2@TixCyOz nanocomposites. The photocatalytic and adsorption properties of TiO2@TixCyOz nanocomposites were studied
