A partial wave analysis is presented of J/ψ → φππ and φKK from a sample of 58M J/ψ events in the BES II detector. The f0(980) is observed clearly in both sets of data, and parameters of the Flatté formula are determined accurately:M = 965± 8 (stat) ±6 (syst) MeV/c, g1 = 165± 10± 15 MeV/c, g2/g1 = 4.21± 0.25± 0.21. The φππ data also exhibit a strong ππ peak centred at M = 1335 MeV/c. It may be f...

OBJECTIVE Colonic mucosal pseudolipomatosis is rare, and its pathogenesis is controversial. A number of mechanisms, including mechanical injury during an endoscopic procedure or chemical injury by disinfectant, seem to contribute to its pathogenesis. MATERIAL AND METHODS This retrospective study examined the colonic biopsies of 1370 patients. These biopsies were preserved at the Department of...

The isosinglet scalar mesons f0(1710), f0(1500), f0(1370) and their mixing are studied. We employ two recent lattice results as the starting point; one is the isovector scalar meson a0(1450) which displays an unusual property of being nearly independent of quark mass for quark masses smaller than that of the strange, and the other is the scalar glueball mass at 1710 MeV in the quenched approxim...

OBJECTIVE To determine whether Ginkgo biloba is effective in treating tinnitus. DESIGN Double blind, placebo controlled trial using postal questionnaires. PARTICIPANTS 1121 healthy people aged between 18 and 70 years with tinnitus that was comparatively stable; 978 participants were matched (489 pairs). INTERVENTION 12 weeks' treatment with either 50 mg Ginkgo biloba extract LI 1370 three...
