The Food Web of Potter Cove (Antarctica): complexity, structure and function [PDF]
Knowledge of the food web structure and complexity are central to better understand ecosystem functioning. A food-web approach includes both species and energy flows among them, providing a natural framework for characterizing species’ ecological roles ...

G Protein‐gekoppelte Rezeptoren (GPCRs) sind wichtige therapeutische Zielstrukturen. Die Modulation der GPCR‐Aktivität über intrazelluläre Bindungsstellen gewinnt zunehmend an Bedeutung. Ein strukturell und computergestützter Ansatz ermöglichte die Entwicklung kleiner, vom G Protein abgeleiteter Peptidomimetika, die gezielt an die intrazelluläre ...

Wir stellen eine kobaltkatalysierte Radikalkaskade vor, die zwei Alken Ausgangsstoffe effizient miteinander verbindet und so in einem einzigen Schritt mehrere Bindungen aufbaut. Der Prozess beginnt mit einem kobaltkatalysierten Wasserstoffatomtransfer an eine Styrol‐Doppelbindung, gefolgt von einer Giese‐Addition.

Multiple Splenic Infarctions Complicating Granulomatosis with Polyangiitis
Background: A 57-year-old patient was admitted for high-grade fever, asthenia, sweating, dry cough and diffuse arthro-myalgias. Two years earlier, elevated titers of anticytoplasmic antibodies (ANCA) of anti-proteinase 3 specificity and renal biopsy led ...

Mittels zeitaufgelöster nativer Massenspektrometrie wird der blaulichtabhängige kinetische Mechanismus der Oligomerisierung von Arabidopsis CRY1 aufgedeckt. Die Oligomerisierung verläuft sequenziell von Monomeren über Dimere zu Tetrameren. Während ATP die Assemblierung fördert, inhibiert BIC1 die Tetramerbildung und dissoziiert diese unabhängig von ...

An abrupt extinction in the Middle Permian (Capitanian) of the Boreal Realm (Spitsbergen) and its link to anoxia and acidification [PDF]
The controversial Capitanian (Middle Permian, 262 Ma) extinction event is only known from equatorial latitudes, and consequently its global extent is poorly resolved.

The quality of political information [PDF]
The article conceptualizes the quality of political information and shows how the concept can be used for empirical research. I distinguish three aspects of quality (intelligibility, relevance, validity) and use them to judge the constituent foundations ...
