Dynamics of Markers of Bone Resorption in Oral Fluid in Patients with Generalized Parodontitis During its Treatment

One of the promising courses in the clinical dentistry is the use of molecular biological markers in patients with periodontal disease. First of all, this is due to the rising trend in the prevalence and risk factors of the disease, which makes relevant finding effective methods for early detection and preventive treatment. 30 patients diagnosed with generalized periodontitis of the I and II degree of severity were selected for the research. In the experimental groups of patients, an immunoassay was used to determine the marker level of bone marrow metabolism (MMP-8) in the oral fluid, in the dynamics of treatment. During the study, the content of this enzyme was found to be indicative of the transformation of the inflammatory process in the gums into the destruction of the alveolar bone. The obtained values of the concentration of MMP-8 in the oral fluid, as well as their dynamics, proved this marker to be indicative of the course of the inflammatory-destructive process in periodontal tissues, and therefore the possibility of its application for the diagnosis and monitoring of the results of treatment of generalized periodontitis

Determination of integral cross sections of

The results of 3H production in Al foil monitors (∼ 59 mg/cm2 thickness) are presented. These foils have been irradiated in 15×15 mm polyethylene bags of ∼ 14 mg/cm2 thickness together with foils of Cr (∼ 395 mg/cm2 thickness) and 56Fe (∼ 332 mg/cm2 thickness) by protons of different energies in a range of 0.04 – 2.6 GeV. The diameters of all the foils were 10.5 mm. The irradiations were carried out at the ITEP accelerator U–10 under the ISTC Project # 3266 in 2006–2009. 3H has been extracted from Al foils using an A307 Sample Oxidizer. An ultra low level liquid scintillation spectrometer Quantulus1220 was used to measure the 3H β–spectra and the SpectraDec software package was applied for spectra processing, deconvolution and 3H activity determination. The values of the Al (p, x)3H reaction cross sections obtained in these experiments are compared with data measured at other labs and with results of simulations by the MCNP6 radiation transport code using the CEM03.03 event generator

Surgycal treatment of the Pectus Excavatum in children

Nuss repair of funnel chests is used increasingly, but has a high bar dislocation rate. The authors intended to reduce this by technical modifications of the original Nuss technique. Methods: In 350 patients from 6 to 17 years of age (mean, 12.4 ± 3.8) were operated by Nuss procedure at the Filatov Children’s Hospital in Moscow for the last 10 years. 37% of patients had Sindromalny pathology. Operation technique: The bars were placed from left to right with use of specially metal conductor; introduced of the T-shaped titanic plate; fixing of both ends of a plate. Plate was removed in 4 years after surgery. Results. Duration of operation averaged 38±7 minutes. Terms of hospitalization averaged 8,5±2 days. Thoracoscopy was used only at 8 (2,2%) patients. From them 4 patients were previous operated by Paltia plate repair, at 3(0,8%) patients – after sternotomiya for correction of CHA and 1 patient after a pulmonectomiya. Simultanny operations were done in 4 (1,1%) patients: Thoracoscopycal ductus arteriosus repair - 2 patients, Thoracoscopycal resection of a lung - 2 patients. Complications: pheumothorax – 2(0,5%), gemathorax– 2(0,5%), plate shift – 1(0,2%) patient. One patient observed hyper correction of the chest. In 98% we had the excellent cosmetic and functional result. Residual deformation was observed - 7 (2%) patients. All patients were reoperated with excellent results. Conclusion. The modified technique more safely and has reduced the incidence of bar dislocation

Von Neumann's quantization of general relativity

[eng] Von Neumann's procedure is applied to quantizing general relativity. Initial data for dynamical variables in the Planck epoch, where the Hubble parameter value coincided with the Planck mass are quantized. These initial data are defined in terms of the Fock orthogonal simplex in the tangent Minkowski spacetime and the Dirac conformal interval. The Einstein cosmological principle is used to average the logarithm of the determinant of the spatial metric over the spatial volume of the visible Universe. The splitting of general coordinate transformations into diffeomorphisms and transformations of the initial data is introduced. In accordance with von Neumann's procedure, the vacuum state is treated is a quantum ensemble that is degenerate in quantum numbers of nonvacuum states. The distribution of the vacuum state leads to the Casimir effect in gravidynamics in just the same way as in electrodynamics. The generating functional for perturbation theory in gravidynamics is found by solving the quantum energy constraint. The applicability range of gravidynamics is discussed along with the possibility of employing this theory to interpret modern observational data

Residual nuclide formation in 206,207,208, natPb and 209Bi induced by 0.04-2.6 GeV protons as well as in 56Fe induced by 0.3-2.6 GeV protons

This work is aimed at experimental determination of independent and cumulative yields of radioactive residual product nuclei in the intermediate energy proton-irradiated thin targets made of highly isotopic enriched and natural lead (206,207,208,natPb), bismuth (209Bi), and highly isotopic enriched iron (56Fe). 5972 independent and cumulative yields of radioactive residuals nuclei have been measured in 55 thin Pb and Bi targets irradiated by 0.04, 0.07, 0.10, 0.15, 0.25, 0.6, 0.8, 1.2, 1.4, 1.6, and 2.6 GeV protons. Besides, 219 yields have been measured in 0.3, 0.5, 0.75, 1.0, 1.5, and 2.6 GeV proton-irradiated Fe target. In both cases, the protons were extracted from the ITEP U-10 synchrotron. The measured data are compared with experimental results obtained elsewhere and with theoretical calculations by seven codes. The predictive power was found to be different for each of the codes tested, but was satisfactory on the whole in the case of spallation products. At the same time, none of the codes can describe well the product yields throughout the whole product mass range, and all codes must be further improved
