BACKGROUND The role of anesthesia as an elicitor of mast cell (MC) mediator release symptoms in mastocytosis is poorly investigated. OBJECTIVE To determine the frequency and type of MC mediator release symptoms during anesthetic procedures in mastocytosis patients. METHODS Medical records were reviewed regarding the anesthetic techniques for 501 mastocytosis patients (459 adults and 42 chil...

The CELESTE atmospheric Cherenkov detector ran until June 2004. It has observed the blazars Mrk 421, 1ES 1426+428 and Mrk 501. We significantly improved our understanding of the atmosphere using a LIDAR, and of the optical through-put of the detector using stellar photometry. The new data analysis provides better background rejection. We present our light curve for Mrk 421 for the 2002-2004 sea...

Neue Mitarbeiter und ebenso Praktikanten sind ein nicht zu unterschätzendes Kapital für eine Bibliothek gleich welcher Größe und Art. Neue Mitarbeiter sind in der Regel hochmotiviert und bringen Ideen und ‚frischen Wind‘ in unter Umständen festgefahrene Strukturen und Arbeitsabläufe. Dabei ist es in erster Linie zweitrangig, ob der neue Mitarbeiter direkt aus der Ausbildung in das Unternehmen s...

We consider the implications of the recent determination of the universal infrared background for the propagation of photons up to 20 TeV from the active galaxy Markarian 501 as observed by HEGRA. At 20 TeV the mean free path for photon-photon collisions on the infrared background would be much shorter than the distance to Markarian 501, implying absorption factors of the order of exp(−10), or ...

The recent detection of gamma radiation from Mkn 501 at energies as high as ∼ 25 TeV suggests stringent upper bounds on the diffuse, far infrared, extragalactic radiation density. The production of electron-positron pairs through photon-photon collisions would prevent gamma photons of substantially higher energies from reaching us across distances of order 100Mpc. However, coherently arriving T...

The BL Lac Object Mkn 501 was in a state of high activity in the TeV range in 1997. During this time Mkn 501 was observed by all Cherenkov-Telescopes of the HEGRA-Collaboration. Part of the data were also taken during moonshine thus providing a nearly continuous coverage for this object in the TeV-range. We have carried out a QPO analysis and found evidence for a 23 day periodicity. We applied ...

Insulin/Insulin-like growth factors play important roles in promoting proliferation, differentiation, growth and development of organisms. In this article, bioinformatics analysis was performed to locate and identify the Bombyx mori insulin-like peptide (BmILP) gene, which had two introns, three exons, and a predicted signal peptide at the front, and it also determined that BmILP was the same t...

We present long-term observations of several VHE (E > 100 GeV) blazars with VERITAS, together with contemporaneous Swift and RXTE Xray data. The observed targets include Mrk 421, Mrk 501, 1ES 2344+514. Strong flux and spectral variability is seen in Mrk 421 on nightly time-scales between January and June 2008, revealing a highly correlated X-ray to GeV/TeV connection. Modest Xray variability is...

Zusammenfassung Dieser Bericht beschreibt die Zielsetzung und aktuelle Ergebnisse des DFG-Sonderforschungsbereichs 501 „Entwicklung großer Systeme mit generischen Methoden“. Dem SFB liegt ein experimenteller Ansatz zugrunde, bei dem die Einzelergebnisse der Teilprojekte in gemeinsamen kontrollierten Experimenten und prototypischen Anwendungsentwicklungen empirisch untersucht werden. Summary Thi...
