We report results from the BICEP2 experiment, a cosmic microwave background (CMB) polarimeter specifically designed to search for the signal of inflationary gravitational waves in the B-mode power spectrum around ℓ∼80. The telescope comprised a 26 cm aperture all-cold refracting optical system equipped with a focal plane of 512 antenna coupled transition(More)
A bacterial P450 monooxygenase-based whole cell biocatalyst using Escherichia coli has been applied in the production of ω-hydroxy dodecanoic acid from dodecanoic acid (C12-FA) or the corresponding methyl ester. We have constructed and purified a chimeric protein where the fusion of the monooxygenase CYP153A from Marinobacter aquaeloei to the reductase(More)
AIMS/METHOD Using high resolution multifluorescence in vivo microscopy, the present study was undertaken to determine the changes in rat hepatic tissue architecture and microvasculature during the growth associated with juvenile maturation and adult senescence, i.e. the age of 1, 3, 12 and 24 months. RESULTS By 1 month of age the liver attained its full(More)
We present results from an analysis of all data taken by the BICEP2 and Keck Array cosmic microwave background (CMB) polarization experiments up to and including the 2014 observing season. This includes the first Keck Array observations at 95 GHz. The maps reach a depth of 50 nK deg in Stokes Q and U in the 150 GHz band and 127 nK deg in the 95 GHz band. We(More)
BACKGROUND Liver surgery for patients with liver metastases from gynecological malignancies, an indicator of advanced cancer disease, has remained unclear in the literature. We therefore analyzed the potential survival benefit of patients with surgically resectable compared to unresectable liver metastases. PATIENTS AND METHODS 43 patients who underwent(More)
A new laccase gene (cotA) was cloned from Bacillus licheniformis and expressed in Escherichia coli. The recombinant protein CotA was purified and showed spectroscopic properties, typical for blue multi-copper oxidases. The enzyme has a molecular weight of approximately 65 kDa and demonstrates activity towards canonical laccase substrates(More)
A fed-batch process utilizing a pET-based expression system (pET28a+ derivative) and E. coli BL21(DE3) as production strain for the heterologous expression of recombinant cytochrome P450 monooxygenase CYP102A1 from Bacillus megaterium was developed. In a first step the expression was optimized during a series of flask experiments testing several parameters(More)
There is a large body of evidence that the liver microcirculation has to be considered as a major target in hepatic ischemia/reperfusion injury. The nature of microvascular injury, which precedes manifestation of hepatic parenchymal tissue damage, includes both hypoxia due to lack of microvascular perfusion (i.e. no-reflow), and a reperfusion-associated(More)
OBJECTIVES To assess the incidence of reactive arthritis (ReA) in an outbreak of salmonella infection in a large cohort of children in Germany. METHODS A few days after the salmonella outbreak all parents of affected children and all paediatricians and general practitioners in the region were provided with detailed information about the possibility of(More)
Neutrinos are elementary particles that carry no electric charge and have little mass. As they interact only weakly with other particles, they can penetrate enormous amounts of matter, and therefore have the potential to directly convey astrophysical information from the edge of the Universe and from deep inside the most cataclysmic high-energy regions. The(More)
