UHV Studies of Methanol Decomposition on Mono- and Bimetallic CoPd Nanoparticles Supported on Thin Alumina Films.
Bimetallic nanoparticles often turn out to be superior to the corresponding monometallic systems with respect to their catalytic properties. To study such effects for the methanol decomposition reaction, model catalysts were prepared by physical vapor deposition of […]

An analysis of candidate autism loci on chromosome 2q24-q33: Evidence for association to the STK39 gene.
A susceptibility locus for autism was identified to the chromosome 2q24-q33 region in independent cohorts of families, especially in subsets clinically defined with phrase speech delay (PSD). In the present work, we screened 84 linkage-informative SNPs covering […]
Dental enamel as a dietary indicator in mammals.
The considerable variation in shape, size, structure and properties of the enamel cap covering mammalian teeth is a topic of great evolutionary interest. No existing theories explain how such variations might be fit for the purpose of breaking food particles down. Borrowing from engineering materials […]
Xanthohumol inhibits inflammatory factor production and angiogenesis in breast cancer xenografts.
Xanthohumol (XN), a natural polyphenol present in beer, is known to exert anti-cancer effects. However, its precise mechanisms are not yet clearly defined. The aim of this study was to investigate the effect of oral administration of XN in breast cancer xenografts […]
Alternative models for the evolution of eyespots and of serial homology on lepidopteran wings.
Serial homology is widespread in organismal design, but the origin and individuation of these repeated structures appears to differ with the different types of serial homologues, and remains an intriguing and exciting topic of research. Here I focus on […]
When did Louis Pasteur present his memoir on the discovery of molecular chirality to the Académie des sciences? Analysis of a discrepancy.
Louis Pasteur presented his historic memoir on the discovery of molecular chirality to the Académie des sciences in Paris on May 22nd, 1848. The literature, however, nearly completely ignores this date, […]
The role of ATF-2 in oncogenesis.
Activating Transcription Factor-2 is a sequence-specific DNA-binding protein that belongs to the bZIP family of proteins and plays diverse roles in the mammalian cells. In response to stress stimuli, it activates a variety of gene targets including cyclin A, cyclin D and c-jun, which are involved in […]

Modulation of VEGF signalling output by the Notch pathway.
The formation of blood vessels within the vascular system entails a variety of cellular processes, including proliferation, migration and differentiation. In many cases, these diverse processes need to be finely coordinated among neighbouring endothelial cells in order to establish a functional vascular network. For […]
