Alkaptonuria is rare disease with deficiency of homogentisate-1,2-dioxygenase enzyme, resulting in excess deposition of homogentisic acid in connective tissue. This deposition leads to ochronosis - brownish-black pigmentation of connective tissue. The result of pigmentation is weakness of connective tissue and, finally, chronic inflammation and osteoarthtritis. Currently specific treatment is absent, only sympothomatic. But total knee arthroplasty has good outcomes in patients of severe ochronotic arthritis similar to osteoarthritic patients without ochronosis. We present a case report of a patient with knee ochronotic arthritis treated with total knee arthroplasty.ΠΠ»ΠΊΠ°ΠΏΡΠΎΠ½ΡΡΠΈΡ ΡΠ²Π»ΡΠ΅ΡΡΡ ΡΠ΅Π΄ΠΊΠΈΠΌ Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠ΅, ΠΏΡΠΈ ΠΊΠΎΡΠΎΡΠΎΠΌ Π΄Π΅ΡΠΈΡΠΈΡ ΡΠ΅ΡΠΌΠ΅Π½ΡΠ° Π³ΠΎΠΌΠΎΠ³Π΅Π½ΡΠΈΠ·Π°Ρ-1.2-Π΄ΠΈΠΎΠΊΡΠΈΠ³Π΅Π½Π°Π·Ρ ΠΏΡΠΈΠ²ΠΎΠ΄ΠΈΡ ΠΊ ΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡ Π³ΠΎΠΌΠΎΠ³Π΅Π½ΡΠΈΠ·ΠΈΠ½ΠΎΠ²ΠΎΠΉ ΠΊΠΈΡΠ»ΠΎΡΡ.

Tritium accumulation and preservation into clay minerals for environmental protection
The comparative analysis of new and previously received data is represented, which allows us to estimate the
influence of hydrodynamic conditions on tritium accumulation and retention in clay minerals. We have received
time dependence of the tritium exchange process with the hydrogen of natural clay mineral matrix, long time halfcycle tritium capture by clay, the part of total tritium activity captured by clay for long time (more then 1 year). The
received data and mathematical modeling let us determine the mineral component of natural clay, which more
efficiently captures and retains tritium and is the best component for making barrier near radioactive tritium waste

Efficacy of surgical treatment of renal form of hyperparathyroidism
Objective: to study the efficacy of surgical treatment of primary hyperparathyroidism in risk of uronephrolithiasis progression. Material and Methods. The research involved 55 patients, the biochemical and clinical parameters before and after treatment with retrospective-prospective method of analysis were studied and analyzed. Results. It is established that the surgical treatment of patients with uronephrolithiasis is proved to be effective in 96,4% of the cases, as it allows to eliminate the classic symptoms of primary hyperparathyroidism, and urolithiasis. Improvement of laboratory hormonal and biochemical indices of mineral metabolism, and, consequently, reducing the severity of risk factors of urolithiasis is marked. Conclusion. Surgical treatment of renal forms of primary hyperparathyroidism is a pathogeneti-cally reasonable method. Parathyroidectomy performed in an adequate amount prevents relapses and progression of diseases that are the consequence of primary hyperparathyroidism.</p

The authors retrospectively reviewed RNIITO Arthroplasty Registry data of revision total hip arthroplasties performed in RNIITO in 3 year period (2011-2013). Part of early revisions within 5 years after the index procedure in general revision structure was 33% . Two hundred seventy three (64%) procedures had infection reason, 79 (19%) - aseptic loosening, 35 (8%) - dislocation and 27 (6%) - periprosthetic fractures in reasons of revision, respectively. More than half of revisions were performed within the first year after the index procedure. Early primary revisions after index total hip arthroplasty were performed in 254 (59,8%)cases, and repeated revisions were performed in 171cases one or more times. Of early primary revisions 125(49,2%) patients had index total hip athroplasty in our hospital, and 129 (50,8%) patients had index total hip athroplasty in other hospitals of Russian Federation. Our THA early revision structure is differs significantly from published in literature, moreover there is difference between revision reasons after primary total hip arthroplasty of our hospital and other hospitals. Revision reasons structure doesnβt show rate of primary THA complications, but defines main problems that should be solved.ΠΡΠ΅Π΄ΡΡΠ°Π²Π»Π΅Π½Ρ Π΄Π°Π½Π½ΡΠ΅ ΡΠ΅Π³ΠΈΡΡΡΠ° ΡΠ½Π΄ΠΎΠΏΡΠΎΡΠ΅Π·ΠΈΡΠΎΠ²Π°Π½ΠΈΡ Π ΠΠΠΠ’Π ΠΈΠΌ.

Purpose. Estimation of critical value of acetabular component uncoverage enabling its implantation without an additional support. Methods. A comparative analysis of an original method for intraoperative measurement of uncoverage space of acetabular component based on the measurement of the depth of uncovered sector with X-ray control by the same technique was carried out. Mathematical computer modeling based on the finite element techniqueand the mechanical experiment were performed. Critical values of uncoverage enabling safe primary fixation of acetabular component were estimated in designed models. Results. High rate of coincidence of direct intraoperative and postoperative measurements by radiograms was obtained, testifying to the possibility of application of this technique of uncoverage estimation at the stage of preoperative X-ray planning in patients with different degree of dysplasia. Using the finite element technique and the mechanical experiment on pelvis models, a possibility of mounting anacetabular component with moderate uncoverage within 25% without screws and with significant uncoverage to 35% with additional two screws fixation was demonstrated.Π¦Π΅Π»Ρ ΡΠ°Π±ΠΎΡΡ - ΠΎΠΏΡΠ΅Π΄Π΅Π»Π΅Π½ΠΈΠ΅ ΠΊΡΠΈΡΠΈΡΠ΅ΡΠΊΠΎΠΉ Π²Π΅Π»ΠΈΡΠΈΠ½Ρ Π½Π΅Π΄ΠΎΠΏΠΎΠΊΡΡΡΠΈΡ Π°ΡΠ΅ΡΠ°Π±ΡΠ»ΡΡΠ½ΠΎΠ³ΠΎ ΠΊΠΎΠΌΠΏΠΎΠ½Π΅Π½ΡΠ°, ΠΏΡΠΈ ΠΊΠΎΡΠΎΡΠΎΠΉ Π²ΠΎΠ·ΠΌΠΎΠΆΠ½Π° Π΅Π³ΠΎ ΠΈΠΌΠΏΠ»Π°Π½ΡΠ°ΡΠΈΡ Π±Π΅Π· ΠΈΡΠΏΠΎΠ»ΡΠ·ΠΎΠ²Π°Π½ΠΈΡ Π΄ΠΎΠΏΠΎΠ»Π½ΠΈΡΠ΅Π»ΡΠ½ΠΎΠΉ ΠΎΠΏΠΎΡΡ.

Asymptotic Expansions for Stationary Distributions of Perturbed Semi-Markov Processes
New algorithms for computing of asymptotic expansions for stationary
distributions of nonlinearly perturbed semi-Markov processes are presented. The
algorithms are based on special techniques of sequential phase space reduction,
which can be applied to processes with asymptotically coupled and uncoupled
finite phase spaces.Comment: 83 page
Demonstration of the temporal matter-wave Talbot effect for trapped matter waves
We demonstrate the temporal Talbot effect for trapped matter waves using
ultracold atoms in an optical lattice. We investigate the phase evolution of an
array of essentially non-interacting matter waves and observe matter-wave
collapse and revival in the form of a Talbot interference pattern. By using
long expansion times, we image momentum space with sub-recoil resolution,
allowing us to observe fractional Talbot fringes up to 10th order.Comment: 17 pages, 7 figure
Kaon Production and Kaon to Pion Ratio in Au+Au Collisions at \snn=130 GeV
Mid-rapidity transverse mass spectra and multiplicity densities of charged
and neutral kaons are reported for Au+Au collisions at \snn=130 GeV at RHIC.
The spectra are exponential in transverse mass, with an inverse slope of about
280 MeV in central collisions. The multiplicity densities for these particles
scale with the negative hadron pseudo-rapidity density. The charged kaon to
pion ratios are and
for the most central collisions. The ratio is lower than the same
ratio observed at the SPS while the is higher than the SPS result.
Both ratios are enhanced by about 50% relative to p+p and +p
collision data at similar energies.Comment: 6 pages, 3 figures, 1 tabl
