Nd2Ir2O7 is a correlated semimetal with the pyrochlore structure, in which competing spin–orbit coupling and electron–electron interactions are believed to induce a time- reversal symmetry-broken Weyl semimetal phase characterized by pairs of topologically protected Dirac points at the Fermi energy1,2,3,4. However, the emergent properties in these materials are far from clear, and exotic...

Isolation of 12 polymorphic tetranucleotide microsatellite markers of the leaf beetle Ophraella communa, a promising Ambrosia biocontrol agent also in Europe

Bordeyne, François ; Müller-Schärer, Heinz ; Bouchemousse, Sarah

In: Biocontrol Science and Technology, 2019, p. 1–8

Following its first record in Europe in 2013, the North American ragweed leaf beetle Ophraella communa, used already as a most successful biocontrol agent against common ragweed in China, is spreading rapidly, asking for a detailed analysis of the potential benefit and risk of this introduction for Europe. Here, we report twelve specific and polymorphic tetranucleotide microsatellite markers,...

Molecularly specific detection of bacterial lipoteichoic acid for diagnosis of prosthetic joint infection of the bone

Pickett, Julie E. ; Thompson, John M. ; Sadowska, Agnieszka ; Tkaczyk, Christine ; Sellman, Bret R. ; Minola, Andrea ; Corti, Davide ; Lanzavecchia, Antonio ; Miller, Lloyd S. ; Thorek, Daniel LJ

In: Bone research, 2018, vol. 6, p. 13

Discriminating sterile inflammation from infection, especially in cases of aseptic loosening versus an actual prosthetic joint infection, is challenging and has significant treatment implications. Our goal was to evaluate a novel human monoclonal antibody (mAb) probe directed against the Gram-positive bacterial surface molecule lipoteichoic acid (LTA). Specificity and affinity were assessed in...

Adaptation of Drosophila to a novel laboratory environment reveals temporally heterogeneous trajectories of selected alleles

Orozco‐Terwengel, Pablo ; Kapun, Martin ; Nolte, Viola ; Kofler, Robert ; Flatt, Thomas ; Schlötterer, Christian

In: Molecular Ecology, 2012, vol. 21, no. 20, p. 4931–4941

The genomic basis of adaptation to novel environments is a fundamental problem in evolutionary biology that has gained additional importance in the light of the recent global change discussion. Here, we combined laboratory natural selection (experimental evolution) in Drosophila melanogaster with genome‐wide next generation sequencing of DNA pools (Pool‐Seq) to identify alleles that are...
