Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Should early improvement be re-defined to better predict the maintenance of response in first-episode schizophrenia patients?
No full textSchennach R, Riesbeck M, Mayr A, Seemuller F, Maier W, Klingberg S, Heuser I, Klosterkotter J, Gastpar M, Schmitt A, Sauer H, Schneider F, Jager M, Wolwer W, Gaebel W, Moller H-J, Riedel M. Should early improvement be re-defined to better predict the maintenance of response in first-episode schizophrenia patients? Objective: To evaluate the predictive validity of early response in first-episode schizophrenia within a 1-year follow-up trial and to compare the resulting cutoff to the currently proposed early response definition (20% improvement by week 2). Method: Receiver operator characteristic (ROC) analyses were used to identify the predictive validity of the psychopathological improvement of treatment from week 1 to week 8, regarding the maintenance of response until week 52 as well as to define the most reasonable cutoff in 132 first-episode patients. The Youden Index (maximum of sensitivity and specificity) was used to compare the newly developed and the commonly used early response definition. Results: Starting with week 6, a reasonable validity to predict the maintenance of response was found (area under the curve=0.721) with the best fitting cutoff being a 51.6% PANSS total score improvement. Using this cutoff 74 patients (56%) were correctly identified to become responder and maintain response during follow-up (sensitivity: 0.747). The Youden Index was higher applying the newly developed early response cutoff featuring higher specificity compared to the commonly used early response definition. Conclusion: Regarding long-term treatment, it seems more appropriate to base predictions of the patient's maintenance of response not before 6weeks of treatment
Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
No full textThis Letter reports a measurement of the CP violation observables SJ/ψK0S and CJ/ψK0S in the decay channel B0→J/ψK0S performed with 1.0 fb−1 of pp collisions at s√=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψK0S=0.73±0.07(stat)±0.04(syst) and CJ/ψK0S=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within

Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
Rationale for continuous dopaminomimetic therapy of Parkinson's disease.
No full textLevodopa combined with carbidopa (Sinemet) remains the most effective approach to the symptomatic relief of Parkinson's disease. Over time, however, an increasing number of parkinsonian patients evidence motor response complications, notably abnormal involuntary movements and motor fluctuations. Clinical pharmacologic studies suggest that these phenomena may arise as a consequence of factors reflecting both natural disease progression and levodopa toxicity. Simple wearing-off responses appear primarily related to advancing degenerative changes afflicting the dopamine system. The appearance of peak-dose dyskinesias and complex, random motor fluctuations of the on-off type, on the other hand, may signal secondary postjunctional changes arising as a consequence of chronic intermittent excitation of postsynaptic dopamine receptors that are normally tonically stimulated. Therapeutically, prompt correction of wearing-off fluctuations can ordinarily be achieved by measures that deliver dopaminomimetics continuously to the central nervous system. In contrast, fluctuations of the on-off type initially persist despite stable circulating levodopa levels. With continuous levodopa treatment, however, the threshold for dyskinesias begins to rise and the dose-response relation shifts to the right; clinically, the severity of both dyskinesias and on-off fluctuations tends to diminish. It is thus tempting to speculate that the early and continuing treatment of Parkinson's disease with compounds providing a relatively constant level of central dopamine stimulation will preclude wearing-off phenomena and mitigate on-off fluctuations and severe dyskinesias
J. M. Coetzee in Context and Theory
No full textNobel Laureate and the first author to win the Booker Prize twice, J.M. Coetzee is perhaps the world's leading living novelist writing in English. Including an international roster of world leading critics and novelists, and drawing on new research, this innovative book analyses the whole range of Coetzee's work, from his most recent novels through his memoirs and critical writing. It offers a range of perspectives on his relationship with the historical, political, cultural and social context of South Africa. It also contextualises Coetzee's work in relation to his literary influences, colonial and post-colonial history, the Holocaust and colonial genocides, the 'politics' and meaning of the Nobel prize in South Africa and Coetzee's very public move from South Africa to Australia. Including a major unpublished essay by leading South African novelist André Brink, this book offers the most up-to-date study of Coetzee's work currently available.Intro -- Contents -- Acknowledgements -- Biographies -- Introduction -- Part I: Context -- 1.
