    Supramolecular thermoplastics and thermoplastic elastomer materials with self-healing ability based on oligomeric charged triblock copolymers

    Supramolecular polymeric materials constitute a unique class of materials held together by non-covalent interactions. These dynamic supramolecular interactions can provide unique properties such as a strong decrease in viscosity upon relatively mild heating, as well as self-healing ability. In this study we demonstrate the unique mechanical properties of phase-separated electrostatic supramolecular materials based on mixing of low molar mass, oligomeric, ABA-triblock copolyacrylates with oppositely charged outer blocks. In case of well-chosen mixtures and block lengths, the charged blocks are phase separated from the uncharged matrix in a hexagonally packed nanomorphology as observed by transmission electron microscopy. Thermal and mechanical analysis of the material shows that the charged sections have a T-g closely beyond room temperature, whereas the material shows an elastic response at temperatures far above this T-g ascribed to the electrostatic supramolecular interactions. A broad set of materials having systematic variations in triblock copolymer structures was used to provide insights in the mechanical properties and and self-healing ability in correlation with the nanomorphology of the materials

    G-arylated hydrogen-bonded cyclic tetramer assemblies with remarkable thermodynamic and kinetic stability

    The preparation and self-assembly of novel G-C dinucleoside monomers that are equipped with electron-poor aryl groups at the G-N2 amino group have been studied. Such monomers associate via Watson-Crick H-bonding into discrete unstrained tetrameric macrocycles that arise as a thermodynamically and kinetically stabilized product in a wide variety of experimental conditions, including very polar solvent environments and low concentrations. G-arylation produces an increased stability of the cyclic assembly, as a result of a subtle interplay between enthalpic and entropic effects involving the solvent coordination sphereFunding from the European Research Council (ERC-StG 279548) and MINECO (CTQ2011-23659) is gratefully acknowledge

    Type 2 diabetes (T2D) and obesity are common chronic disorders with multifactorial etiology. In our study, we performed an exome sequencing analysis of 110 patients of Russian ethnicity together with a multi-perspective approach based on biologically meaningful filtering criteria to detect novel candidate variants and loci for T2D and obesity. We have identified several known single nucleotide polymorphisms (SNPs) as markers for obesity (rs11960429), T2D (rs9379084, rs1126930), and body mass index (BMI) (rs11553746, rs1956549 and rs7195386) (p < 0.05). We show that a method based on scoring of case-specific variants together with selection of protein-altering variants can allow for the interrogation of novel and known candidate markers of T2D and obesity in small samples. Using this method, we identified rs328 in LPL (p = 0.023), rs11863726 in HBQ1 (p = 8 × 10−5), rs112984085 in VAV3 (p = 4.8 × 10−4) for T2D and obesity, rs6271 in DBH (p = 0.043), rs62618693 in QSER1 (p = 0.021), rs61758785 in RAD51B (p = 1.7 × 10−4), rs34042554 in PCDHA1 (p = 1 × 10−4), and rs144183813 in PLEKHA5 (p = 1.7 × 10−4) for obesity; and rs9379084 in RREB1 (p = 0.042), rs2233984 in C6orf15 (p = 0.030), rs61737764 in ITGB6 (p = 0.035), rs17801742 in COL2A1 (p = 8.5 × 10−5), and rs685523 in ADAMTS13 (p = 1 × 10−6) for T2D as important susceptibility loci in Russian population. Our results demonstrate the effectiveness of whole exome sequencing (WES) technologies for searching for novel markers of multifactorial diseases in cohorts of limited size in poorly studied populations

    adaptive activities, reserve capacity, healthSummary: Introduction. At present with an increase of the share of the diseases of the system of blood circulation in the structure of morbidity and mortality of population with the significant rejuvenation of the diseased contingent the important criterion of effectiveness of social-hygienic measures achieved is health status of the students of higher medical establishments, which determines the duration of the period of effective working activity of the future health care professionals. Aim. To assess the state of adaptive and compensatory capacity of an organism of students in higher medical educational institutions. Material and methods. Assessment the physical development, nutritional status, the state of the functional system of an organism of female students were carried out before and after the examination. Object of research - the second-year female students of the Faculties of General Medicine (25 subjects) and Pediatrics (25 subjects) of the Grodno State Medical University at the age of 18-20 years. Results. Adaptive potential as for the conditions of academic activity of the majority of students corresponds to normative values. The maximum of adaptive processes is reached toward the end of the third month of instruction, the minimum - to the end of summer examination session. Conclusions. Adaptation tension mechanisms are more expressed in the students of the Faculty of Pediatrics

    Resolved epilepsy: an updated insight

    Get PDF
    Classification of epilepsy is of great importance at the stages of rehabilitation when the disease is considered resolved. This is the time to address various aspects of etiology, pathogenesis, compensation and resolution of epilepsy and to decide upon further medical care. Materials and methods. Here we review clinical-neurophysiological, experimentalpsychological, and neuroimaging results of anti-epileptic treatment and its discontinuation in seizure-free patients. We also discuss the adoption of the new international classification of ILAE 2017 in the domestic epileptology and analyze clinical cases of 270 patients with epilepsy who were in control of seizures for up to 8 years. Results. The study revealed the clinical, neuropsychological and neurophysiological signs of epilepsy regression in patients with long-term control of seizures. In 85% of these patients, seizures were under control; in 45% of them, the issue of “resolution of epilepsy” was a matter of discussion. In this regard, we address the timing and indications for the discontinuation of antiepileptic drugs. Conclusion. The prolonged absence of seizures is due to an inhibition of epileptic activity at the neuronal level with a gradual restoration of the antiepileptic system during 3-5 years of seizure-free period; this mechanism is reflected in the new classification. The data obtained in the present study support the decision of the Russian League against Epilepsy to introduce the new classification of epilepsy proposed by ILAE in 2017. The new term “resolved epilepsy” has been adopted for use in patients previously referred to as “practically recovered”
