    The variability of nucleotide repeats is considered one of the causes of diseases, but their biological function is not understood. In recent years, the interaction of miRNAs and piRNAs with the mRNAs of genes responsible for developing neurodegenerative and oncological diseases and diabetes have been actively studied. We explored candidate genes with nucleotide repeats to predict associations with miRNAs and piRNAs. The parameters of miRNAs and piRNA binding sites with mRNAs of human genes having nucleotide repeats were determined using the MirTarget program. This program defines the start of the initiation of miRNA and piRNA binding to mRNAs, the localization of miRNA and piRNA binding sites in the 5'-untranslated region (5'UTR), coding sequence (CDS) and 3'-untranslated region (3'UTR); the free energy of binding; and the schemes of nucleotide interactions of miRNAs and piRNAs with mRNAs. The characteristics of miRNAs and piRNA binding sites with mRNAs of 73 human genes were determined. The 5'UTR, 3'UTR and CDS of the mRNAs of genes are involved in the development of neurodegenerative, oncological and diabetes diseases with GU, AC dinucleotide and CCG, CAG, GCC, CGG, CGC trinucleotide repeats. The associations of miRNAs, piRNAs and candidate target genes could be recommended for developing methods for diagnosing diseases, including neurodegenerative diseases, oncological diseases and diabetes

    Lanthanum-strontium manganites doped with zinc are studied by the method of electron magnetic resonance. Nano-objects with ferromagnetically correlated spins, which behave themselves like superparamagnetic particles in the magnetic resonance spectrum, have been found in the paramagnetic phase. The temperature dependences of the resonance magnetic field and magnetic resonance linewidth for La1 - xSrxMn0.925Zn0.075O3 ceramic samples at temperatures ranging from 100 to 340 K have been analyzed on the basis of the Raikher-Stepanov theory of superparamagnetic particles. The magnetic moment, anisotropy field, and characteristic size of the regions of the ferromagnetically correlated spins have been determined. Β© 2013 Pleiades Publishing, Inc

    We investigate the magnetic properties of the system Eu 0.6La0.4-xSrxMnO3 with 0.1≀x≀0.3 by means of magnetic susceptibility and electron spin resonance measurements. Ferromagnetic resonance signals are observed in the paramagnetic regime from above the magnetic ordering temperature TN up to approximately room temperature. This regime is characterized by the coexistence of ferromagnetic entities within the globally paramagnetic phase. The results are compared to the Griffiths scenario reported in La1-xSr xMnO3.

    Introduction. A decrease in the number of patients with tuberculosis of the bone system coincides with an increase in the number of indications and methods for operational treatment. The continuing development in skeletal tuberculosis surgery techniques determines the search for a material capable of replacing autologous bone. Therefore, the main purpose of this paper is to enhance the results of treatment of spinal caries to speed up treatment of tuberculous osteomyelitis by applying collagen material and to solve the issues of orthopedic alignment for TB patients.Materials and methods. Surgical treatment was carried out on 32 patients in 2016–2018. The patients were divided into several groups: 18 underwent transpedicular fixation of the spine, 2 had concomitant HIV-infection, 2 underwent necrectomy of vertebral bodies with anterior spondylodesis lift system, 1 underwent necrectomy of vertebral bodies with bone autoplasty and with plate fixation, 2 had cervical spine fixation, while 2 patients with pulmonary tuberculosis in the humerus traumatic fracture received intramedullary surgery.Results. 31 patients reported a positive dynamic following surgery, while a fatal outcome not connected with the surgery was experienced in one case. Complications included allergic reaction in one case, while three patients developed postoperative wound seroma (both patients having HIV infection). One patient reported pain in the lower extremities following TPF. 3 patients with osteitis underwent necrectomy and filling of cavities with collagen material. Wounds were healed by secondary healing, while no rejection of collagen material took place.Conclusions. Introduction of collagen material in osteitis treatment can speed up fistula healing. The research work demonstrated the possibility of providing trauma care to patients under the conditions of an antitubercular centre.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Neutral tritium gas reduction in the KATRIN differential pumping sections

    Get PDF
    The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to measure the effective electron anti-neutrino mass with an unprecedented sensitivity of 0.2 eV/c20.2\,\mathrm{eV}/\mathrm{c}^2, using Ξ²\beta-electrons from tritium decay. The electrons are guided magnetically by a system of superconducting magnets through a vacuum beamline from the windowless gaseous tritium source through differential and cryogenic pumping sections to a high resolution spectrometer and a segmented silicon pin detector. At the same time tritium gas has to be prevented from entering the spectrometer. Therefore, the pumping sections have to reduce the tritium flow by more than 14 orders of magnitude. This paper describes the measurement of the reduction factor of the differential pumping section performed with high purity tritium gas during the first measurement campaigns of the KATRIN experiment. The reduction factor results are compared with previously performed simulations, as well as the stringent requirements of the KATRIN experiment.Comment: 19 pages, 4 figures, submitted to Vacuu

    Monitoring of the operating parameters of the KATRIN Windowless Gaseous Tritium Source

    The Karlsruhe Tritium Neutrino (KATRIN) experiment will measure the absolute mass scale of neutrinos with a sensitivity of \m_{\nu} = 200 meV/c2^2 by high-precision spectroscopy close to the tritium beta-decay endpoint at 18.6 keV. Its Windowless Gaseous Tritium Source (WGTS) is a beta-decay source of high intensity (101110^{11}/s) and stability, where high-purity molecular tritium at 30 K is circulated in a closed loop with a yearly throughput of 10 kg. To limit systematic effects the column density of the source has to be stabilised at the 0.1% level. This requires extensive sensor instrumentation and dedicated control and monitoring systems for parameters such as the beam tube temperature, injection pressure, gas composition and others. Here we give an overview of these systems including a dedicated Laser-Raman system as well as several beta-decay activity monitors. We also report on results of the WGTS demonstrator and other large-scale test experiments giving proof-of-principle that all parameters relevant to the systematics can be controlled and monitored on the 0.1% level or better. As a result of these works, the WGTS systematics can be controlled within stringent margins, enabling the KATRIN experiment to explore the neutrino mass scale with the design sensitivity.Comment: 32 pages, 13 figures. modification to title, typos correcte

    The KArlsruhe TRItium Neutrino (KATRIN) experiment will measure the absolute mass scale of neutrinos with a sensitivity of mnu = 200 meV/c2 by high-precision spectroscopy close to the tritium beta-decay endpoint at 18.6 keV. Its Windowless Gaseous Tritium Source (WGTS) is a beta-decay source of high intensity (1011 sβˆ’1) and stability, where high-purity molecular tritium at 30 K is circulated in a closed loop with a yearly throughput of 10 kg. To limit systematic effects the column density of the source has to be stabilized at the 10βˆ’3 level. This requires extensive sensor instrumentation and dedicated control and monitoring systems for parameters such as the beam tube temperature, injection pressure, gas composition and so on. In this paper, we give an overview of these systems including a dedicated laser-Raman system as well as several beta-decay activity monitors. We also report on the results of the WGTS demonstrator and other large-scale test experiments giving proof-of-principle that all parameters relevant to the systematics can be controlled and monitored on the 10βˆ’3 level or better.

    Introduction. Various techniques of controllable level of negative pressure are presently a trending treatment of purulent-necrotic wounds. Despite the widespread view in the literature about the obvious benefits of this method, there are still no extensive research, free from commercial interests. In this context, the main objective of this study was to evaluate early results of vacuum therapy in complex treatment of purulonecrotic wound. Materials and methods. The work includes data of multi-dimensional follow-up study with non-parallel (historical) control. Retrospective study included analysis of case histories in the period 2010 - 2012 (140 patients), prospective study was to analyse the effectiveness of vacuum therapy in complex treatment of purulent diseases in patients hospitalized in purulent surgery department at Republic Clinical Hospital. G.G. Kuvatov UFA) during the period 2012-2016 (142 patients). Results. The findings show that the application of negative pressure treatment method in complex treatment of patients with infected wounds of soft tissues is indicated in cases where there has been a slowing of wounds cleansing and reparative processes - the method allows to reduce number of bandaging for a patient, the timing of wound cleansing and accelerate the transition to the phase of plastic closure of the wound. Conclusions. To reduce the risk of bleeding on vacuum therapy, following extensive surgical interventions, it is optimal to comply with temporary pause between surgical effect on wound and installing of apparatus NPWT (8-16 hours). The best effect in the treatment of wounds can be achieved when applying the following NPWT mode: the first 24 hours after the beginning of vacuum therapy - a constant level of negative pressure at 100-140 mm Hg.; second day and further - intermittent level of negative pressure with alternating modes at 60-75 mm Hg. - 5 minutes and 120-130 mm Hg. -5 minutes.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.
