PECULIARITIES OF IMMUNITY IN PATIENTS WITH DIABETES MELLITUS AND CHRONIC PYELONEPHRITIS

The pro- and antiinflammatory cytokines participate in antiinfective immunity, that is why it is necessary study their peculiarities in determination of the role in the immunopathogenesis of pyelonephritis, including complications of diabetes mellitus (DM). The purpose of the work is to study the immune status and levels of pro- and antiinflammatory blood cytokines in the patients with chronic pyelonephritis (CPN), to determine the peculiarities in cases of DM. Materials and methods. The immuno-enzymic method ELISA and the corresponding test-systems were used to study the levels of cytokines in blood and also standard immunity indices. Results. The analysis showed the significant increase in levels of all studied pro- (TNF-б, MCP-1, IL-17, -23) and antiinflammatory (IL-4, TGF-в) cytokines in all patients with CPN and in every group – with (2) and without DM (3). In 3 gr. (CPN+DM) the CD4+/CD8+ are significantly lower, while in IgM, МСР-1 and TNF-б levels – higher than in the 1 gr. (DM without CPN), and IL-4 , NGAL – than in 2 gr. (CPN without DM). Conclusion. The high level of cytokines (TNF-б, MCP-1 and IL-23) in blood confirms their important role in CPN+DM and CPN without DM. In patients with CPN+DM marked reduction in regulatory index (CD4+/CD8+) and higher levels of proinflammatory cytokines (TNF-б, MCP-1). Our investigation showed that NGAL level in serum was increased more significantly in 3 gr.; this fact may confirm that renal disfunction was more severe in patients with CPN+DM

Measurements of π−\pi ^- production in 7^7Be + 9^9Be collisions at beam momenta from 19A to 150A GeV ⁣/ ⁣cA\,\text{ GeV }\!/\!c in the NA61/SHINE experiment at the CERN SPS

The NA61/SHINE experiment at the CERN Super Proton Synchrotron (SPS) studies the onset of deconfinement in hadron matter by a scan of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents results on inclusive double-differential spectra, transverse momentum and rapidity distributions and mean multiplicities of $\pi ^\pm$, $K^\pm$, p and $\bar{p}$ produced in the 20% most central$^7$Be+$^9$Be collisions at beam momenta of 19A, 30A, 40A, 75A and 150A ${\mathrm{Ge} \mathrm{V}}\!/\!c$. The energy dependence of the $K^\pm$/$\pi ^\pm$ ratios as well as of inverse slope parameters of the $K^\pm$ transverse mass distributions are close to those found in inelastic p+p reactions. The new results are compared to the world data on p+p and Pb+Pb collisions as well as to predictions of the Epos, Urqmd, Ampt, Phsd and Smash models

Proton-proton interactions and onset of deconfinement

The experiment of the NA61/SHINE Collaboration at the CERN SPS is performing a unique study of the phase diagram of strongly interacting matter by varying collision energy and nuclear mass number of colliding nuclei. In central Pb+Pb collisions, the experiment of the NA49 Collaboration found structures in the energy dependence of several observables in the energy range of the CERN SPS that had been predicted for the transition to a deconfined phase. New measurements of the NA61/SHINE Collaboration find intriguing similarities in p+p interactions for which no deconfinement transition is expected at the energies of the SPS. Possible implications will be discussed

Measurements of Ξ−{\Xi }{^-} and Ξ‾+\overline{\Xi }{^+} production in proton–proton interactions at sNN\sqrt{s_{NN}}=17.3 GeV = 17.3 GeV in the NA61/SHINE experiment

International audienceThe production of $\Xi (1321)^{-}$ and $\overline{\Xi }(1321)^{+}$ hyperons in inelastic p+p interactions is studied in a fixed target experiment at a beam momentum of 158 $\hbox {Ge}\hbox {V}\!/\!c$. Double differential distributions in rapidity ${y}$ and transverse momentum $p_{T}$ are obtained from a sample of 33M inelastic events. They allow to extrapolate the spectra to full phase space and to determine the mean multiplicity of both ${\Xi }{^-}$ and $\overline{\Xi }{^+}$. The rapidity and transverse momentum spectra are compared to transport model predictions. The ${\Xi }{^-}$ mean multiplicity in inelastic p+p interactions at 158 $\hbox {Ge}\hbox {V}\!/\!c$ is used to quantify the strangeness enhancement in A+A collisions at the same centre-of-mass energy per nucleon pair
