Effect of different fillers on thermal conductivity, tribological properties of Polyamide 6.

An influence of different filler types and filler content on the thermal and abrasive wear properties of polyamide-6 is investigated. AlO, MgO, two glass powders with different SiO contents, and natural zeolite powder were selected as fillers. The fillers individually were added to the polymer matrix in proportions of 50 and 70% by weight.

Inactivated tick-borne encephalitis vaccine elicits several overlapping waves of T cell response.

The development and implementation of vaccines have been growing exponentially, remaining one of the major successes of healthcare over the last century. Nowadays, active regular immunizations prevent epidemics of many viral diseases, including tick-borne encephalitis (TBE). Along with the generation of virus-specific antibodies, a highly effective vaccine should induce T cell responses providing long-term immune defense.

Aberrant Splicing of Impairs Beta-Cell Differentiation and Proliferation by ER Stress in the Isogenic iPSC Model of Neonatal Diabetes.

One of the causes of diabetes in infants is the defect of the insulin gene (INS). Gene mutations can lead to proinsulin misfolding, an increased endoplasmic reticulum (ER) stress and possible beta-cell apoptosis. In humans, the mechanisms underlying beta-cell failure remain unclear.

Structural differences and adsorption behaviour of alkaline metals doped zinc oxide nanoparticles.

Nanotechnology plays a vital role in all the scientific fields including environmental research due to their surface: volume ratio compared to bulk materials. Recent studies prove their effectiveness as pollutant removal and remediation practices. Zinc oxide (ZnO) nanoparticles a multifunctional material with distinct properties and their doped counterparts were widely being studied in different fields of science.

Deregulation of Trace Amine-Associated Receptors (TAAR) Expression and Signaling Mode in Melanoma.

Trace amine-associated receptors (TAARs) interact with amine compounds called "trace amines" which are present in tissues at low concentrations. Recently, TAARs expression in neoplastic tumors was reported. In this study, TAARs expression was analyzed in public RNAseq datasets in nevi and melanoma samples and compared to the expression of dopamine receptors (DRDs) that are known to be involved in melanoma pathogenesis.

Generation of an induced pluripotent stem cell line MNDINSi001-A from a patient with neonatal diabetes caused by a heterozygous INS mutation.

Insulin gene (INS) mutations prove to be the second most common cause of permanent neonatal diabetes. Here, we report the generation of iPSC line from a patient, heterozygous for the intronic INS mutation that presumably leads to aberrant splicing. Dermal fibroblasts were reprogrammed using non-integrating RNA-based vector.

Precise tracking of vaccine-responding T cell clones reveals convergent and personalized response in identical twins.

T cell receptor (TCR) repertoire data contain information about infections that could be used in disease diagnostics and vaccine development, but extracting that information remains a major challenge. Here we developed a statistical framework to detect TCR clone proliferation and contraction from longitudinal repertoire data. We applied this framework to data from three pairs of identical twins immunized with the yellow fever vaccine.

Phase Transformation and Morphology Evolution of TiCuNiSn₅ during Mechanical Milling.

Nanocrystalline/amorphous powder was produced by ball milling of TiCuNiSn₅ (at.%) master alloy. Both laser diffraction particle size analyzer and scanning electron microscope (SEM) were used to monitor the changes in the particle size as well as in the shape of particles as a function of milling time.

Quantitative profiling reveals minor changes of T cell receptor repertoire in response to subunit inactivated influenza vaccine.

Vaccination against influenza is widely used to protect against seasonal flu epidemic although its effectiveness is debated. Here we performed deep quantitative T cell receptor repertoire profiling in peripheral blood of a healthy volunteer in response to trivalent subunit influenza vaccine. We did not observe significant rebuilding of peripheral blood T cell receptors composition in response to vaccination.

VDJdb: a curated database of T-cell receptor sequences with known antigen specificity.

The ability to decode antigen specificities encapsulated in the sequences of rearranged T-cell receptor (TCR) genes is critical for our understanding of the adaptive immune system and promises significant advances in the field of translational medicine. Recent developments in high-throughput sequencing methods (immune repertoire sequencing technology, or RepSeq) and single-cell RNA sequencing technology have allowed us to obtain huge numbers of TCR sequences from donor samples and link them to T-cell phenotypes. However, our ability to annotate these TCR sequences still lags behind, owing to the enormous diversity of the TCR repertoire and the scarcity of available data on T-cell specificities.

Persisting fetal clonotypes influence the structure and overlap of adult human T cell receptor repertoires.

The diversity of T-cell receptors recognizing foreign pathogens is generated through a highly stochastic recombination process, making the independent production of the same sequence rare. Yet unrelated individuals do share receptors, which together constitute a "public" repertoire of abundant clonotypes. The TCR repertoire is initially formed prenatally, when the enzyme inserting random nucleotides is downregulated, producing a limited diversity subset.

Tracking T-cell immune reconstitution after TCRαβ/CD19-depleted hematopoietic cells transplantation in children.

αβT-cell-depleted allogeneic hematopoietic cell transplantation holds promise for the safe and accessible therapy of both malignant and non-malignant blood disorders. Here we employed molecular barcoding normalized T-cell receptor (TCR) profiling to quantitatively track T-cell immune reconstitution after TCRαβ-/CD19-depleted transplantation in children. We demonstrate that seemingly early reconstitution of αβT-cell counts 2 months after transplantation is based on only several hundred rapidly expanded clones originating from non-depleted graft cells.

[The new technologies of kinesiotherapy for the rehabilitation of the patients suffering from the post-stroke locomotor disorders].

This paper was designed to report the results of the application of two therapeutic modalities for the rehabilitation of 44 patients presenting with post-stroke locomotor disorders in the form of spastic hemiparesis. The patients allocated to the main group were treated with the use of the new kinesiotherapeutic methods including cryomassage and the Armeo robotic complex. The patients of the control group had to perform traditional therapeutic physical exercises in combination with classical massage and remedial gymnastics.

Collision Cross Sections for O + Ar(+) Collisions in the Energy Range 0.03-500 eV.

The interatomic potentials of the a(2)Π and b(2)Π states of the OAr(+) molecule are calculated using the relativistic complete-active space Hartree-Fock method followed by a multireference configuration interaction calculation with an aug-cc-pwCVNZ-DK basis sets where N is 4 and 5. The calculations were followed by an extrapolation to the complete basis set limit. An avoided crossing between the two potential energy curves is found at an internuclear separation of 5.

[Dynamics of the functional characteristics of the microcirculation system in the women of late reproductive age presenting with chronic endometritis under effect of contrast massage].

The objective of the present work was to study the functional characteristics of the microcirculation system in the women of late reproductive age presenting with chronic endometritis before and after a course of contrast massage. Three types of functional changes in the microcirulation system were distinguished based on the results of laser-assisted Doppler flowmetry. All of them were characterized by high coefficients of correlation with the results of dopplerometry of uterine blood flow and underwent dynamic changes in the course of the treatment.

Equal impact of diffusion and DNA binding rates on the potential spatial distribution of nuclear factor κB transcription factor inside the nucleus.

There are two physical processes that influence the spatial distribution of transcription factor molecules entering the nucleus of a eukaryotic cell, the binding to genomic DNA and the diffusion throughout the nuclear volume. Comparison of the DNA-protein association rate constant and the protein diffusion constant may determine which one is the limiting factor. If the process is diffusion-limited, transcription factor molecules are captured by DNA before their even distribution in the nuclear volume.

Site-specific differential effects of once-yearly zoledronic acid on the hip assessed with quantitative computed tomography: results from the HORIZON Pivotal Fracture Trial.

Unlabelled: We used new approaches to the analysis of diagnostic scans to detect changes in bone density in different regions of the hip after 3 years of treatment with the zoledronic acid. We showed that the drug significantly increases hip bone density compared to placebo at regions where hip fractures usually occur.

Introduction: This study aims to identify whether treatment with zoledronic acid exerts site-specific differential effects on volumetric bone mineral density (vBMD) at the hip.

High-resolution crystal structure of the isolated ribosomal L1 stalk.

The crystal structure of the isolated full-length ribosomal L1 stalk, consisting of Thermus thermophilus ribosomal protein L1 in complex with a specific 80-nucleotide fragment of 23S rRNA, has been solved for the first time at high resolution. The structure revealed details of protein-RNA interactions in the L1 stalk. Analysis of the crystal packing enabled the identification of sticky sites on the protein and the 23S rRNA which may be important for ribosome assembly and function.

Purification and functional analysis of recombinant Acholeplasma laidlawii histone-like HU protein.

HU is a most abundant DNA-binding protein in bacteria. This protein is conserved either in its heterodimeric form or in one of its homodimeric forms in all bacteria, in plant chloroplasts, and in some viruses. HU protein non-specifically binds and bends DNA as a hetero- or homodimer and can participate in DNA supercoiling and DNA condensation.

Disruption of shape complementarity in the ribosomal protein L1-RNA contact region does not hinder specific recognition of the RNA target site.

The formation of a specific and stable complex between two (macro)molecules implies complementary contact surface regions. We used ribosomal protein L1, which specifically binds a target site on 23S rRNA, to study the influence of surface modifications on the protein-RNA affinity. The threonine residue in the universally conserved triad Thr-Met-Gly significant for RNA recognition and binding was substituted by phenylalanine, valine and alanine, respectively.

Generation of new TRAIL mutants DR5-A and DR5-B with improved selectivity to death receptor 5.

TRAIL (tumor necrosis factor (TNF) related apoptosis-inducing ligand) has been introduced as an extrinsic pathway inducer of apoptosis that does not have the toxicities of Fas and TNF. However, the therapeutic potential of TRAIL is limited because of many primary tumor cells are resistant to TRAIL. Despite intensive investigations, little is known in regards to the mechanisms underlying TRAIL selectivity and efficiency.

[Permissible degree of reduction of diet caloricity for obese patients].

A study was made of the effects of diets with varying degree of caloricity reduction at the expense of the decreased content of carbohydrates and fat (1200, 600, 300 kcal and calorie-free "zero" diet) on some indicators of lipid, carbohydrate, protein and mineral metabolism comparatively to the patients' clinical status. A group of patients receiving the diet with a caloricity of 1800 kcal served as control. It was shown that the diet with an average reduction of caloricity (1200 kcal) may be applied to the treatment of obese patients for a long period of time both on in- and outpatient basis.
