Diagnostic significance of TLR2 and TLR4 receptors on lymphoid cells as a marker of the progression of periodontal inflammation associated with key periodontal pathogenic species <i>F. alocis</i> and <i>P. gingivalis</i>

The aim of the work was to evaluate the diagnostic value of TLR2 and TLR4 expression on periodontal and peripheral blood lymphoid cells by immunofluorescence microscopy in patients with chronic periodontitis associated with key periodontal pathogenic species Filifactor alocis, Porphyromonas gingivalis. Materials and methods. The study included 150 patients 88 (59%) women and 62 (41%) men aged 18 to 73 years with chronic periodontitis in the acute phase (CP) and 32 people without signs of chronic periodontal inflammation. To confirm the diagnosis of periodontitis, the Multident-5 PCR kit was used (detection of P. gingivalis, Prevotella intermedia, Tannerella forsythia, Treponema denticola, Aggregatibacter actinomycetemcomitans), as well as rt-PCR for F. alocis and P. gingivalis in the contents of the periodontal pocket (NPF GenLab, Russia). To evaluate cells carrying CD282 and CD284 markers, gingival fluid flushes from the periodontal pocket with Hanks' solution were used. The isolated cells were stained with antibodies to CD282 markers (corresponding to TLR2 receptor) or CD284 (corresponding to TLR4 receptor) labeled with FITC, and fixed with paraformaldehyde for subsequent immunofluorescence microscopy. Results. The expression of TLR2 and TLR4 on peripheral blood and gingival fluid leukocytes was studied in individuals with healthy periodontitis and patients with chronic periodontitis associated with F. alocis, P. gingivalis. According to the results of PCR, the detection rate of F. alocis and P. gingivalis was 64 and 62.7%, respectively, which confirmed their dominance in the microbial association. It was found that the expression of TLR2 and TLR4 on peripheral blood lymphoid cells varied in humans. The possible diagnostic significance of this phenomenon in assessing the progression of chronic periodontitis is discussed. Conclusion. In patients with chronic periodontitis associated with the dominance of periodontopathogenic species F. alocis, P. gingivalis, the multidirectional expression of TLR2 and TLR4 on peripheral blood cells was observed, which may have diagnostic significance in assessing the progression of periodontal diseases

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.
