J Org Chem. 2015 Jun 19;80(12):6173-92. doi: 10.1021/acs.joc.5b00661. Epub 2015 Jun 05.

A new generation of rod-shaped dipolar molecular rotors designed for controlled insertion into channel arrays in the surface of hexagonal tris(o-phenylenedioxy)cyclotriphosphazene (TPP) has been designed and synthesized. Triptycene is used as a stopper intended to prevent complete insertion, forcing...

[reaction: see text] We report the synthesis of cis-endo-bicyclo[1.1.1]pentane-1,2,3,4-tetracarboxylic acid and several of its derivatives with differentiated bridgehead and bridge positions, starting with tetracyclo[3.2.0.0(1,6).0(2,6)]heptane.

Herpesviruses and Newcastle disease viruses in white storks (Ciconia ciconia).

Avian pathology : journal of the W.V.P.A

Kaleta EF, Kummerfeld N.
PMID: 18766791
Avian Pathol. 1983;12(3):347-52. doi: 10.1080/03079458308436177.

Three herpesviruses were isolated from white storks (Ciconia ciconia). All isolates reacted in cross-neutralisation tests with homologous antisera and with sera prepared against a herpesvirus from a black stork (Ciconia nigra). These data indicate serologic relatedness of the herpesviruses...

Duck viral hepatitis type 1 vaccination: monitoring of the immune response with a microneutralisation test in Pekin duck embryo kidney cell cultures.

An outbreak of reovirus infection with high mortality in two groups of recently imported psittacine birds is reported. The disease in the two species involved, African grey parrots (Psittacus erithacus erithacus) and Australian king parrots (Alisterus scapularis), had differences...

Arrays of dipolar molecular rotors in Tris(o-phenylenedioxy) cyclotriphosphazene.

Topics in current chemistry

Regular two-dimensional or three-dimensional arrays of mutually interacting dipolar molecular rotors represent a worthy synthetic objective. Their dielectric properties, including possible collective behavior, will be a sensitive function of the location of the rotors, the orientation of their axes,...
