Pollen analysis, chronology and palaeomagnetism of three Late Weichselian sites in southern Sweden

Popular Abstract in Swedish Pollenanalys, kronologi och paleomagnetism på tre senglaciala lokaler i södra Sverige Senglaciala sjösediment (d.v.s. avsatta under slutet av den senaste istiden) från tre bassänger i södra Sverige, Torreberga i Skåne, Farslycke i Blekinge och Bolmen i Småland, har studerats med avseende på pollensammansättning och paleomagnetism. Åldersbestämning och tidsjämförelser b

Identification of a Ser/Thr cluster in the C-terminal domain of the human prostaglandin EP4-R essential for agonist-induced beta-arrestin1 recruitment that differs from the apparent principal phosphorylation site.

hEP4-R (human prostaglandin E2 receptor, subtype EP4) is a Gs-linked heterotrimeric GPCR (G-protein-coupled receptor). It undergoes agonist-induced desensitization and internalization that depend on the presence of its C-terminal domain. Desensitization and internalization of GPCRs are often linked to agonist-induced b-arrestin complex formation, which is stabilized by phosphorylation. Subsequentl

Screening the molecular surface of human anticoagulant protein C: a search for interaction sites

Protein C (PC), a 62 kDa multi-modular zymogen, is activated to an anticoagulant serine protease (activated PC or APC) by thrombin bound to thrombomodulin on the surface of endothelial cells. PC/APC interacts with many proteins and the characterisation of these interactions is not trivial. However, molecular modelling methods help to study these complex biological processes and provide basis for r

Unusual CO adsorption sites on vanadium oxide-Pd(111) "inverse model catalyst" surfaces

The morphology, structure, and reactivity of vanadium oxide-decorated Pd(111) surfaces, which have been subjected to oxidation and reduction treatments, have been investigated by scanning tunneling microscopy (STM), high-resolution electron energy loss spectroscopy (HREELS), and high-resolution X-ray photoelectron spectroscopy (HR-XPS) with synchrotron radiation combined with ab initio density fun

The identification of novel, high affinity AQP9 inhibitors in an intracellular binding site

Background: The involvement of aquaporin (AQP) water and small solute channels in the etiology of several diseases, including cancer, neuromyelitis optica and body fluid imbalance disorders, has been suggested previously. Furthermore, results obtained in a mouse model suggested that AQP9 function contributes to hyperglycemia in type-2 diabetes. In addition, the physiological role of several AQP fa
