    We have developed a method for obtaining the total proteome of Bacillus anthracis spores, which combines efficient protein extraction with reliable disinfection of samples. We used 7 strains of B. anthracis: 4 plasmid-free, 3 diplasmid, one of which with an atypical type of capsule formation in air. The schemes for isolating the total spore proteome were tested using various lysis solutions in the presence of bacterial protease inhibitors, with the inclusion of the stages of treatment of spores with trichloroacetic acid and mechanical disintegration and with their exclusion. The quality and completeness of the extraction of the total proteome of the spores of the samples was assessed in one-dimensional (1D) and twodimensional (2D) electrophoresis. Treatment of spores with trichloroacetic acid increased the reliability of material disinfection and reduces the loss of the final product. Mechanical disintegration after treatment of spores with lysing solutions increases the completeness of extraction of spore proteins in a wide range of molecular weights and facilitated the process of sterilizing filtration. Final filtration of the lysate through a PVDF filter with a pore size of 0.22 ΞΌm provided additional decontamination of samples without reducing their quality. Thus, the use of the proposed sample preparation scheme makes it possible to obtain complete protein extracts of spores of B. anthracis strains, suitable for comparative analysis of the proteome and search for a possible correlation with the features phenotypic properties and mechanisms that ensure the preservation of the pathogen anthrax in environmental objects, including soilΠ Π°Π·Ρ€Π°Π±ΠΎΡ‚Π°Π½ ΠΌΠ΅Ρ‚ΠΎΠ΄ получСния Ρ‚ΠΎΡ‚Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ ΠΏΡ€ΠΎΡ‚Π΅ΠΎΠΌΠ° спор Bacillus anthracis, ΡΠΎΡ‡Π΅Ρ‚Π°ΡŽΡ‰ΠΈΠΉ ΡΡ„Ρ„Π΅ΠΊΡ‚ΠΈΠ²Π½ΡƒΡŽ ΡΠΊΡΡ‚Ρ€Π°ΠΊΡ†ΠΈΡŽ Π±Π΅Π»ΠΊΠΎΠ² с Π½Π°Π΄Π΅ΠΆΠ½Ρ‹ΠΌ ΠΎΠ±Π΅Π·Π·Π°Ρ€Π°ΠΆΠΈΠ²Π°Π½ΠΈΠ΅ΠΌ ΠΎΠ±Ρ€Π°Π·Ρ†ΠΎΠ².

    Spinodal decomposition, nuclear fog and two characteristic volumes in thermal multifragmentation

    Full text link
    Thermal multifragmentation of hot nuclei is interpreted as the nuclear liquid-fog phase transition inside the spinodal region. The experimental data for p(8.1GeV) + Au collisions are analyzed within the framework of the statistical multifragmentation model (SMM) for the events with emission of at least two IMFs. It is found that the partition of hot nuclei is specified after expansion to a volume equal to Vt = (2.6+-0.3) Vo, with Vo as the volume at normal density. However, the freeze-out volume is found to be twice as large: Vf = (5+-1) Vo.Comment: 8 pages, 6 figures, to be published in Nucl.Phys.

    Influence of the Ratio of Metal Composed Nanocomposites Fe-Co / C on Phase Composition

    Metalcarbon nanocomposites based on polyacrylonitrile and nickel chloride are synthesized under the influence of infrared heat. The resulting materials represent a system of carbon matrix formed during the carbonization of PAN, and distributed in it nickel nanoparticles. The average size of the nanoparticles in the nanocomposite was 15-25 nm. It was found that the distribution of nickel nanoparticles sizes is determined by temperature synthesis nanocomposite. Thus with increasing temperature, the predominant average particle size of the metal increases, and the distribution is spread and shifted toward larger sizes.

    Until recently, the pathogenesis of purulent hidradenitis was a little- and sporadically studied issue, which invariably created difficulties in the therapeutic treatment of this disease. Its often severe recurrency rate, high incidence and the lack of effective treatment have predetermined the urgency of the problem and raised the scientific and practical interest in this field among the scientists worldwide. Recent data indicate a significant role of damage-associated molecular patterns (DAMP) and the activation of congenital immunity, associated with Th17 lymphocytes, in the development of inflammatory disease. Likewise, the violation of the transmission of the cellular Notch signaling pathway plays an important role in the development of purulent hidradenitis.Β Π”ΠΎ Π½Π΅Π΄Π°Π²Π½Π΅Π³ΠΎ Π²Ρ€Π΅ΠΌΠ΅Π½ΠΈ ΠΏΠ°Ρ‚ΠΎΠ³Π΅Π½Π΅Π· Π³Π½ΠΎΠΉΠ½ΠΎΠ³ΠΎ Π³ΠΈΠ΄Ρ€Π°Π΄Π΅Π½ΠΈΡ‚Π° являлся ΠΌΠ°Π»ΠΎΠΈΠ·ΡƒΡ‡Π΅Π½Π½ΠΎΠΉ ΠΈ Π½Π΅Ρ€Π΅ΡˆΠ΅Π½Π½ΠΎΠΉ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΠΎΠΉ, Ρ‡Ρ‚ΠΎ Π½Π΅ΠΈΠ·ΠΌΠ΅Π½Π½ΠΎ создавало трудности Π² Ρ‚Π΅Ρ€Π°ΠΏΠΈΠΈ этого заболСвания.

    Nuclear multifragmentation and fission: similarity and differences

    Full text link
    Thermal multifragmentation of hot nuclei is interpreted as the nuclear liquid--fog phase transition deep inside the spinodal region. The experimental data for p(8.1GeV) + Au collisions are analyzed. It is concluded that the decay process of hot nuclei is characterized by two size parameters: transition state and freeze-out volumes. The similarity between dynamics of fragmentation and ordinary fission is discussed. The IMF emission time is related to the mean rupture time at the multi-scission point, which corresponds to the kinetic freeze-out configuration.Comment: 7 pages, 3 Postscript figures, Proceedings of IWM 2005, Catani

    Purulent hydradenitis is a chronic relapsing disease that affects 4% of the population, caused by uncontrolled growth of hair follicle and apocrine gland cells, which leads to the development of autoimmune and then septic inflammation. The provoking factors are obesity, smoking, formation of apocrine glands in the body. The variety of subordinates of Suppurative hydradenitis, differences in the prognosis and course of the disease, as well as the need to manage patients with this pathology in the surgical department, determine the standardization of the therapeutic algorithm and the objectification of the degree of clinical response to the therapy using scoring scales.Π“Π½ΠΎΠΉΠ½Ρ‹ΠΉ Π³ΠΈΠ΄Ρ€Π°Π΄Π΅Π½ΠΈΡ‚ β€” хроничСскоС Ρ€Π΅Ρ†ΠΈΠ΄ΠΈΠ²ΠΈΡ€ΡƒΡŽΡ‰Π΅Π΅ Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠ΅, ΠΏΠΎΡ€Π°ΠΆΠ°ΡŽΡ‰Π΅Π΅ 4% насСлСния, ΠΏΡ€ΠΈΡ‡ΠΈΠ½ΠΎΠΉ ΠΊΠΎΡ‚ΠΎΡ€ΠΎΠ³ΠΎ являСтся Π½Π΅ΠΊΠΎΠ½Ρ‚Ρ€ΠΎΠ»ΠΈΡ€ΡƒΠ΅ΠΌΡ‹ΠΉ рост ΠΊΠ»Π΅Ρ‚ΠΎΠΊ волосяного Ρ„ΠΎΠ»Π»ΠΈΠΊΡƒΠ»Π° ΠΈ Π°ΠΏΠΎΠΊΡ€ΠΈΠ½ΠΎΠ²ΠΎΠΉ ΠΆΠ΅Π»Π΅Π·Ρ‹, Ρ‡Ρ‚ΠΎ ΠΏΡ€ΠΈΠ²ΠΎΠ΄ΠΈΡ‚ ΠΊ Ρ€Π°Π·Π²ΠΈΡ‚ΠΈΡŽ Π°ΡƒΡ‚ΠΎΠΈΠΌΠΌΡƒΠ½Π½ΠΎΠ³ΠΎ, Π° Π·Π°Ρ‚Π΅ΠΌ сСптичСского воспалСния.

    Drift and diffusion of ions in a cavity having the shape of oblate ellipsoid of revolution are considered. The obtained approximate relationship, between the time of drift and diffusion filling of deep cavity with ions, contains the applied voltage and the ratio of cavity size to the distance between electrodes. It shows that in the performed experiments with the device for water capacitive deionization the filling of electrodes by ions was carried out, mainly, due to diffusion.Розглянуто Π΄Ρ€Π΅ΠΉΡ„ Ρ‚Π° Π΄ΠΈΡ„ΡƒΠ·Ρ–ΡŽ Ρ–ΠΎΠ½Ρ–Π² Ρƒ ΠΏΠΎΡ€ΠΎΠΆΠ½ΠΈΠ½Ρ–, яка ΠΌΠ°Ρ” Ρ„ΠΎΡ€ΠΌΡƒ ΡΠΏΠ»ΡŽΡΠ½ΡƒΡ‚ΠΎΠ³ΠΎ Сліпсоїду обСртання.

    AbstractFor the purpose of reprocessing of irradiated nuclear fuel from the water-cooled graphite-moderated pressure-tube reactor named AMB from decomissioned Russian β€œAtom Peaceful Big”, modernization of the process flow-sheet of the RT-1 plant is being carried out at PA Mayak with participation of FSUE KRI and VNIINM. A particular AMB SNF feature is extremely broad range of fuel compounds with the main ones being the uranium-molybdenum metal, uranium oxide and uranium carbide compositions usually dispersed in magnesium or calcium. Wide range of fuel compositions required to amend SNF dissolution, extraction processing, evaporation of high-level radioactive wastes and vitrification of high-level radioactive wastes. The above set of laboratory research was completed with dynamic tests using samples of AMB from the water-cooled graphite-moderated pressure-tube reactor. Tests have shown the possibility of processing the entire range of AMB SNF at the radiochemical plant RT-1 plant of the PA Mayak. Thus, the ability of the RT-1 plant to process different fuel compositions, including the long-term research reactor fuel have been proved experimentally
