A First Search for coincident Gravitational Waves and High Energy Neutrinos using LIGO, Virgo and ANTARES data from 2007

We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at high energy. Our search uses neutrinos detected by the underwater neutrino telescope ANTARES in its 5 line configuration during the period January - September 2007, which coincided with the fifth and first science runs of LIGO and Virgo, respectively. The LIGO-Virgo data were analysed for candidate gravitational-wave signals coincident in time and direction with the neutrino events. No significant coincident events were observed. We place limits on the density of joint high energy neutrino - gravitational wave emission events in the local universe, and compare them with densities of merger and core-collapse events.Comment: 19 pages, 8 figures, science summary page at http://www.ligo.org/science/Publication-S5LV_ANTARES/index.php.

Mammalian pheromones VIII Chemical characterization of preorbital gland secretion of grey duiker, Sylvicapra grimmia (Artiodactyla: Bovidae)

Using gas chromatography-mass spectrometry 33 constituents of the preorbital gland of the grey duiker, Sylvicapra grimmia, were identified as unbranched alkanes, 2-alkanones, alkanals, alkanoic acids, alkan-4-olides, as well as 3-methyl-3-buten-1-ol, (Z)-9-octadecenoic acid, benzyl cyanide, diethyl sulfoxide, 2-isobutyl-1,3-thiazole, 2-isobutyl-4,5-dihydro-1,3-thiazole, and 3,4-epoxy-2-dodecanone. Determination of the relative concentrations of these components in a limited number of secretion samples taken from males and females revealed that in these samples the two thiazole derivatives and the epoxy ketone were present in consistently and significantly higher concentrations in male than in female secretions. This suggests that they could act as sex recognition cues. © 1990 Plenum Publishing Corporation.Articl

Safety and efficacy of pantoprazole 40 mg daily as relapse prophylaxis in patients with healed reflux oesophagitis - A 2-year follow-up

Background: Pantoprazole is a benzimidazole derivative which selectively inhibits the proton pump H+, K+-ATPase, necessary for the final step in gastric acid secretion. Aim: To assess safety and efficacy of oral pantoprazole (40 mg o.d.) used as a prophylaxis against relapse in patients with healed reflux oesophagitis during an open-label, 2-year study. Methods: Outpatients (n = 157) with healed stage II or III reflux oesophagitis (Savary-Miller classification) were enrolled into a long-term, multicentre maintenance study. Endoscopy was performed at entry into the study, after 12 and 24 months, or when disease-specific symptoms occurred on more than three consecutive days. Symptoms were assessed at 3-monthly intervals. Endoscopically confirmed relapses (at least stage I) were evaluated as treatment failures. Results: Of the 178 adverse events, experienced by 88 (56%) patients (intention-to-treat population), 12 (7%) were assessed by the investigators as possibly related to the study medication. Median serum gastrin levels increased from a baseline of 46 ng/L to 90 ng/L, reaching a plateau after 9 months. For the intention-to-treat population the endoscopic remission rates after 12 and 24 months were 87% and 76%, respectively (Life-Table survival analysis, Kaplan-Meier). Conclusion: Pantoprazole 40 mg proved to be safe and efficacious during a 2-year prophylaxis treatment in patients with healed reflux oesophagitis.Articl
