    Neurogenic mechanisms in bladder and bowel ageing

    Get PDF
    The prevalence of both urinary and faecal incontinence, and also chronic constipation, increases with ageing and these conditions have a major impact on the quality of life of the elderly. Management of bladder and bowel dysfunction in the elderly is currently far from ideal and also carries a significant financial burden. Understanding how these changes occur is thus a major priority in biogerontology. The functions of the bladder and terminal bowel are regulated by complex neuronal networks. In particular neurons of the spinal cord and peripheral ganglia play a key role in regulating micturition and defaecation reflexes as well as promoting continence. In this review we discuss the evidence for ageing-induced neuronal dysfunction that might predispose to neurogenic forms of incontinence in the elderly

    NA62 experiment at CERN SPS

    No full text
    The NA62 experiment at SPS is a continuation of the long standing CERN kaon physics program. The high statistics and the unprecedent precision allow to probe the Standard Model and test the description of the strong interactions at low energy. The final results on the the lepton universality test by measuring the ratio RK = Γ(K+ → e+ν)/Γ(K+ → µ+ν) and the study of the K± → π±γγ decay are presented. The major goal of the NA62 experiment is to perform a measurement of the Br(K+ → π+νν̄) with a precision of 10% in two years of data taking. The detector setup together with the analysis technique is described

    The NA62 Experiment aims to measure the branching ratio of the ultra-rare K+ !p+n ¯ n decay with 10% precision, collecting 100 events with the SM branching fraction in 3 years of data taking. The NA62 experimental strategy and the detector layout are describe

    Precision tests of the Standard Model with kaon decays at CERN

    No full text
    Recent results and prospects for precision tests of the Standard Model in kaon decay in flight experiments at CERN are presented. A measurement of the ratio of leptonic decay rates of the charged kaon at a 0.4% precision constrains the parameter space of new physics models with, for example, an extended Higgs sector. Searches for neutrino mass states and the dark photon in the 100 MeV = c 2 mass range based on samples collected in 2003-2007 are in progress and prospects will be discussed. The NA62 experiment starting in 2014 will search for a range of lepton number and lepton flavour violating decays of the charged kaon and the neutral pion at improved sensitivities down to 10-12, probing new physics scenarios involving, for example, heavy Majorana neutrinos. Prospects for the NA62 L0 trigger strategy for rare and forbidden decays will be discussed

    The NA62 experiment at CERN SPS recorded in 2007 a large sample of K+μ+νμK^+\to\mu^+\nu_\mu decays. A peak search in the missing mass spectrum of this decay is performed. In the absence of observed signal, the limits obtained on B(K+μ+νh)\mathcal{B}(K^+\to\mu^+\nu_h) and on the mixing matrix element Uμ42|U_{\mu4}|^2 are reported. The upgraded NA62 experiment started data taking in 2015, with the aim of measuring the branching fraction of the K+π+ννˉK+\to\pi^+\nu\bar{\nu} decay. An update on the status of the experiment is presented.The NA62 experiment at CERN SPS recorded in 2007 a large sample of K+μ+νμK^+ \to \mu^+ \nu_{\mu} decays.
