    There is represented  the current classification of interferon inducers of various chemical groups related to antiviral agents, described the mechanisms of synthesis of different types of endogenous interferon in blood serum. The effectiveness of methylglucamine acridonacetates  in integrated treatment of chronic hepatitis C, tuberculosis with  HIV infection background, chronic brucellosis, arboviral diseases, including West Nile fever , as well as influenza and acute respiratory infections are shown.  For successful treatment of acute and chronic diseases with  endogenous interferon inducers should be applied as early as possible, at an average level of viremia , to enhance the effect of drugs with the directed etiotropic action and immunomodulators , which achieves the optimal pharmacotherapeutic effect.Представлена современная  классификация  индукторов  интерферона различных химических групп, относящихся к противовирусным средствам, описаны механизмы синтеза разных типов эндогенного интерферона в сыворотке крови. Продемонстрирована эффективность метилглукамина акридонацетата в комплексном лечении хронического гепатита С, туберкулеза на фоне ВИЧ-инфекции, хронического бруцеллеза, арбовирусных заболеваний, включая лихорадку Западного Нила, а также гриппа и острых респираторных инфекций. Для успешного лечения острых и хронических заболеваний индукторы эндогенного интерферона следует применять как можно раньше, при среднем уровне  виремии,  для усиления эффекта  препаратов  направленного этиотропного действия и иммуномодуляторов, что обеспечивает  достижение оптимального фармакотерапевтического эффекта.

    Measurement of the Z boson differential cross section in transverse momentum and rapidity in proton-proton collisions at 8 TeV

    Get PDF
    We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy s=8 TeV, corresponding to an integrated luminosity of 19.7 fb-1. The Z boson is identified via its decay to a pair of muons. The measurement provides a precision test of quantum chromodynamics over a large region of phase space. In addition, due to the small experimental uncertainties in the measurement the data has the potential to constrain the gluon parton distribution function in the kinematic regime important for Higgs boson production via gluon fusion. The results agree with the next-to-next-to-leading-order predictions computed with the fewz program. The results are also compared to the commonly used leading-order MadGraph and next-to-leading-order powheg generators. © 2015 CERN for the benefit of the CMS Collaboration

    Phenomenological MSSM interpretation of CMS searches in pp collisions at √s=7 and 8 TeV

    Get PDF
    Searches for new physics by the CMS collaboration are interpreted in the framework of the phenomenological minimal supersymmetric standard model (pMSSM). The data samples used in this study were collected at root s = 7 and 8 TeV and have integrated luminosities of 5.0 fb(-1) and 19.5 fb(-1), respectively. A global Bayesian analysis is performed, incorporating results from a broad range of CMS supersymmetry searches, as well as constraints from other experiments. Because the pMSSM incorporates several well-motivated assumptions that reduce the 120 parameters of the MSSM to just 19 parameters defined at the electroweak scale, it is possible to assess the results of the study in a relatively straightforward way. Approximately half of the model points in a potentially accessible subspace of the pMSSM are excluded, including all pMSSM model points with a gluino mass below 500 GeV, as well as models with a squark mass less than 300 GeV. Models with chargino and neutralino masses below 200 GeV are disfavored, but no mass range of model points can be ruled out based on the analyses considered. The nonexcluded regions in the pMSSM parameter space are characterized in terms of physical processes and key observables, and implications for future searches are discussed

    Search for neutral resonances decaying into a Z boson and a pair of b jets or τ leptons

    Get PDF
    A search is performed for a new resonance decaying into a lighter resonance and a Z boson. Two channels are studied, targeting the decay of the lighter resonance into either a pair of oppositely charged τ leptons or a bb‾ pair. The Z boson is identified via its decays to electrons or muons. The search exploits data collected by the CMS experiment at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.8 fb −1 . No significant deviations are observed from the standard model expectation and limits are set on production cross sections and parameters of two-Higgs-doublet models
