Using of Tendinous Plasty in Treatment of Patients with Flexor Tendons of 2–5 Fingers Injury in “Critical” Zone

Injury of both superficial and deep tendons of fingers flexors needs to carry out tendinous plasty with excision of distal part of superficial flexor muscle tendon. Use of length measuring method for tendinous transplant allows us to avoid the flexion contracture in future and appearance of functional insufficiency of flexion during postoperative period and rehabilitation of patient

Optimization of surgical treatment tactics at a customary shoulder dislocation

&nbsp;Saratov Journal of Medical Scientific Research 2018; 14 (2): 240-243. The aim: the optimization of surgical treatment tactics at a customary shoulder dislocation, based on "on-track Hill-Sachs / off-track Hill-Sachs" concept. Material and Methods. The research group consists of 42 patients aged from 19 to 52 years with chronic recurrent anterior shoulder instability, who underwent a surgical treatment to restore previous shoulder anatomic and topographic correlations. Patients were divided into two subgroups according to diagnostic arthroscopy results. The first subgroup includes 14 patients with impaction visualized (off-track Hill-Sachs), the second one — 28 patients with head shoulder stability (on-track Hill-Sachs). Patients of the first subgroup underwent open surgical intervention according to Bristow — Latarjetand shoulder arthroscopic repair was carried out in the second group. Results. One month after the surgical treatment median total estimated figure exceeded by 1.8 times in patients of the first subgroup and by 1.2 times, by Rowe, in patients of the second subgroup and decreased by 2.1 times in patients of the first subgroup and by 1.7 times, by DASH, in the second subgroup in comparison with the indices before the operation, that was illustrative of a good treatment result. Six months after the operation median total estimated figure exceeded by 1.2 times, by Rowe, in patients both of the first subgroup and the second subgroup and decreased by 2 and 2.1 times, by DASH, in patients of the first and the second group, relatively in comparison with the indices found one month after the operation, that was illustrative of an excellent treatment result in the late postoperative period. Conclusion. Patients with anterior shoulder instability caused by a glenoid fossa deficiency less than 25% in combination with off-track Hill-Sachs lesion, the most convenient way is the replacement of the bone loss by coracoid process transposition. In patients with on-track Hill-Sachs lesion arthroscopic repair is preferable.</p

Measurement of the View the tt production cross-section using eμ events with b-tagged jets in pp collisions at √s = 13 TeV with the ATLAS detector

This paper describes a measurement of the inclusive top quark pair production cross-section (σtt¯) with a data sample of 3.2 fb−1 of proton–proton collisions at a centre-of-mass energy of √s = 13 TeV, collected in 2015 by the ATLAS detector at the LHC. This measurement uses events with an opposite-charge electron–muon pair in the final state. Jets containing b-quarks are tagged using an algorithm based on track impact parameters and reconstructed secondary vertices. The numbers of events with exactly one and exactly two b-tagged jets are counted and used to determine simultaneously σtt¯ and the efficiency to reconstruct and b-tag a jet from a top quark decay, thereby minimising the associated systematic uncertainties. The cross-section is measured to be: σtt¯ = 818 ± 8 (stat) ± 27 (syst) ± 19 (lumi) ± 12 (beam) pb, where the four uncertainties arise from data statistics, experimental and theoretical systematic effects, the integrated luminosity and the LHC beam energy, giving a total relative uncertainty of 4.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. A fiducial measurement corresponding to the experimental acceptance of the leptons is also presented

Search for TeV-scale gravity signatures in high-mass final states with leptons and jets with the ATLAS detector at sqrt [ s ] = 13TeV

A search for physics beyond the Standard Model, in final states with at least one high transverse momentum charged lepton (electron or muon) and two additional high transverse momentum leptons or jets, is performed using 3.2 fb−1 of proton–proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2015 at √s = 13 TeV. The upper end of the distribution of the scalar sum of the transverse momenta of leptons and jets is sensitive to the production of high-mass objects. No excess of events beyond Standard Model predictions is observed. Exclusion limits are set for models of microscopic black holes with two to six extra dimensions

Search for strong gravity in multijet final states produced in pp collisions at √s=13 TeV using the ATLAS detector at the LHC

A search is conducted for new physics in multijet final states using 3.6 inverse femtobarns of data from proton-proton collisions at √s = 13TeV taken at the CERN Large Hadron Collider with the ATLAS detector. Events are selected containing at least three jets with scalar sum of jet transverse momenta (HT) greater than 1TeV. No excess is seen at large HT and limits are presented on new physics: models which produce final states containing at least three jets and having cross sections larger than 1.6 fb with HT > 5.8 TeV are excluded. Limits are also given in terms of new physics models of strong gravity that hypothesize additional space-time dimensions

Operation and performance of the ATLAS semiconductor tracker

The semiconductor tracker is a silicon microstrip detector forming part of the inner tracking system of the ATLAS experiment at the LHC. The operation and performance of the semiconductor tracker during the first years of LHC running are described. More than 99% of the detector modules were operational during this period, with an average intrinsic hit efficiency of (99.74±0.04)%. The evolution of the noise occupancy is discussed, and measurements of the Lorentz angle, δ-ray production and energy loss presented. The alignment of the detector is found to be stable at the few-micron level over long periods of time. Radiation damage measurements, which include the evolution of detector leakage currents, are found to be consistent with predictions and are used in the verification of radiation background simulations

Search for H→γγ produced in association with top quarks and constraints on the Yukawa coupling between the top quark and the Higgs boson using data taken at 7 TeV and 8 TeV with the ATLAS detector

A search is performed for Higgs bosons produced in association with top quarks using the diphoton decay mode of the Higgs boson. Selection requirements are optimized separately for leptonic and fully hadronic final states from the top quark decays. The dataset used corresponds to an integrated luminosity of 4.5 fb−14.5 fb−1 of proton–proton collisions at a center-of-mass energy of 7 TeV and 20.3 fb−1 at 8 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. No significant excess over the background prediction is observed and upper limits are set on the tt¯H production cross section. The observed exclusion upper limit at 95% confidence level is 6.7 times the predicted Standard Model cross section value. In addition, limits are set on the strength of the Yukawa coupling between the top quark and the Higgs boson, taking into account the dependence of the tt¯H and tH cross sections as well as the H→γγ branching fraction on the Yukawa coupling. Lower and upper limits at 95% confidence level are set at −1.3 and +8.0 times the Yukawa coupling strength in the Standard Model
