    • The momentum distribution of electrons from decays of heavy flavor (charm and bottom) for midrapidity |y|< 0.35 in p+p collisions at s=200 GeV has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over the transverse momentum range 0.3 < p(T)< 9 GeV/c. Two independent methods have been used to determine the heavy-flavor yields, and the results are in good agreement with each other. A fixed-order-plus-next-to-leading-log perturbative QCD calculation agrees with the data within the theoretical and experimental uncertainties, with the data/theory ratio of 1.71 +/- 0.02(stat)+/- 0.18(sys) for 0.3 < p(T)< 9 GeV/c. The total charm production cross section at this energy has also been deduced to be sigma(cc)=567 +/- 57(stat)+/- 193(sys) mu b.

  • Rofecoxib in the acute treatment of migraine: a randomized controlled clinical trial
  • 2006

    • OBJECTIVE: To investigate the efficacy, tolerability, and safety of rofecoxib and ibuprofen for acute migraine treatment. BACKGROUND: Rofecoxib was effective and well tolerated in a previous study of treatment of a single migraine attack. We sought to replicate these findings for a single attack and also study the clinical profile of rofecoxib in the acute treatment of multiple migraine attacks. Ibuprofen was included as a reference nonselective NSAID. METHODS: Adult migraineurs (n = 783) treated one migraine attack with either rofecoxib (25 or 50 mg), ibuprofen 400 mg, or placebo in a randomized, double-blind study. Patients could elect to enroll in a 3-month double-blind extension phase. RESULTS: In the single-attack phase, headache relief at 2 hours postdose was reported by 59.4%, 62.2%, and 57.7% of patients who took rofecoxib 25 mg, rofecoxib 50 mg, and ibuprofen 400 mg, respectively, versus 30.5% for placebo (all P < .001 vs placebo). The active drugs were statistically superior to placebo on a variety of additional measures. In the extension phase, the mean percentage of patients' attacks with headache relief at 2 hours postdose was 61.8% for rofecoxib 25 mg, 65.4% for rofecoxib 50 mg, and 59.3% for ibuprofen 400 mg. The mean percentage of patients' attacks with 24-hour sustained headache relief was greater for rofecoxib 50 mg (52.0%) than for rofecoxib 25 mg (47.8%, P < .050) or ibuprofen (39.0%, P < .010). In the single-attack phase, the adverse event rate was higher for rofecoxib 50 mg (37.8%) than placebo (27.8%, P < .050); rates were similar to placebo for rofecoxib 25 mg (32.0%, n.s.) and ibuprofen 400 mg (28.1%, n.s.). In the extension phase, treatment groups had similar adverse event rates. CONCLUSIONS: Rofecoxib 25 and 50 mg and ibuprofen 400 mg were effective and generally well tolerated in the acute treatment of migraine.
