In Arabidopsis thaliana and Oryza sativa, two types of PI 4-kinase (PI4Ks) have been isolated and functionally characterized. The alpha-type PI4Ks (similar to 220 kDa) contain a PH domain, which is lacking in beta-type PI4Ks (similar to 120 kDa). beta-Type PI4Ks, exemplified by Arabidopsis AtPI4K beta and rice OsPI4K2, contain a highly charged repetitive segment designated PPC (Plant PI4K Charged) region, which is an unique domain only found in plant beta-type PI4Ks at present. The PPC region has a length of similar to 300 amino acids and harboring 11 (AtPI4K beta) and 14 (OsPI4K2) repeats, respectively, of a 20-aa motif. Studies employing a modified yeast-based "Sequence of Membrane- Targeting Detection'' system demonstrate that the PPC(OsPI4K2) region, as well as the former 8 and latter 6 repetitive motifs within the PPC region, are able to target fusion proteins to the plasma membrane. Further detection on the transiently expressed GFP fusion proteins in onion epidermal cells showed that the PPC(OsPI4K2) region alone, as well as the region containing repetitive motifs 1-8, was able to direct GFP to the plasma membrane, while the regions containing less repetitive motifs, i.e. 6, 4, 2 or single motif(s) led to predominantly intracellular localization. Agrobacterium-mediated transient expression of PPC-GFP fusion protein further confirms the membrane-targeting capacities of PPC region. In addition, the predominant plasma membrane localization of AtPI4Kb was mediated by the PPC region. Recombinant PPC peptide, expressed in E. coli, strongly binds phosphatidic acid, PI and PI4P, but not phosphatidylcholine, PI5P, or PI(4,5) P-2 in vitro, providing insights into potential mechanisms for regulating sub- cellular localization and lipid binding for the plant beta-type PI4Ks

This paper focuses on the characterization and use of polymer-modified phosphatidylcholine (PC)/sodium dodecyl sulfate (SDS)-based inverse microemulsions as a template phase for BaSO4 nanoparticle formation. The area of the optically clear inverse microemulsion phase in the isooctane/hexanol/water/PC/SDS system is not significantly changed by adding polyelectrolytes, i.e., poly(diallyldimethylammonium chloride) (PDADMAC), or amphoteric copolymers of diallyldimethylammonium chloride and maleamid acid to the SDS-modified inverse microemulsion. Shear experiments show non- Newtonian flow behavior and oscillation experiments show a frequency-dependent viscosity increase (dilatant behavior) of the microemulsions. Small amounts of bulk water were identified by means of differential scanning calorimetry. One can conclude that the macromolecules are incorporated into the individual droplets, and polymer-filled microemulsions are formed. The polymer-filled microemulsions were used as a template phase for the synthesis of BaSO4 nanoparticles. After solvent evaporation the nanoparticles were redispersed in water and isooctane, respectively. The polymers incorporated into the microemulsion are involved in the redispersion process and influence the size and shape of the redispersed BaSO4 particles in a specific way. The crystallization process mainly depends on the type of solvent and the polymer component added. In the presence of the cationic polyelectrolyte PDADMAC the crystallization to larger cubic crystals is inhibited, and layers consisting of polymer-stabilized spherical nanoparticles of BaSO4 (6 nm in size) will be observed.

Die Klosterkirche der Benediktinerabtei Ottobeuren ist eines der Hauptwerke des europäischen Barock. Die CD-ROM bietet Besuchern und einem kunsthistorisch interessiertem Publikum eine einzigartige Präsentation und völlig neue Perspektiven. Im Barockzeitalter kombinierten die Künstler bei der Innenausstattung von Kirchen, gezielt ölbilder, Stuck und Fresken mit der Architektur zu umfassenden theologischen Gesamtkunstwerken. Hinter dem Gewimmel aus Heiligen, Allegorien, Engeln und Reliquiaren vermag der kundig geführte Betrachter vielerlei Bezüge zu entdecken. Die CD-ROM gibt Antwort auf Fragen die sich jeder Besucher eines barocken Kirchenraumes schon einmal gestellt haben dürfte. Weshalb liegen in den Schausärgen Skelette? Warum stürzen Teufel aus dem Bild? Wozu mahnen die unterschiedlichen Tugenden? Aus dem Inhalt: · Vollständige digitale Rekonstruktion einer der berühmtesten Kirchen des europäischen Barock · ca. 500 hochauflösende Bilder sowie Kamerafahrten, 1300 Textseiten · über 70 Fachtheologen, Kunsthistoriker, Seelsorger, Lehrer und Studierende aus Deutschland, österreich und den USA interpretieren den Innenraum der Basilika Ottobeuren. Der verlinkte Himmel - ein Kirchenbesuch der besonderen Art!
