Infection of Aedes albopictus with chikungunya virus rectally administered by enema.

Chikungunya virus (CHIKV) is an alphavirus transmitted by Aedes albopictus and Aedes aegypti mosquitoes in tropical areas of Africa, Asia, and the islands of the Indian Ocean. In 2007 and 2009, CHIKV was transmitted outside these tropical areas and caused geographically localized infections in people in Italy and France. To temporally and spatially characterize CHIKV infection of Ae.

Synthesis, structure and electrochemistry of isomeric nickel(II) complexes of a [9]ane fused cyclam macrotricycle: evidence for a stable trans-IV and a redox induced rearrangement in a trans-I conformation.

The macrotricyclic ligand, 1,11-dithia-4,8,14,18-tetraaza-[5,2,2,5]-eicosane, L3 has been synthesized from cyclam. Both the cis- and the trans- isomers of the Ni(ii) complexes have been prepared and characterized by single crystal X-ray crystallography. In the cis-[Ni(trans-I, syn-L3)](Cl(2))·4H(2)O, the syn-isomer of L3 is present in which the cyclam ring adopts a trans-I stereochemistry.

Synthesis and structure of a new macrotricyclic ligand that encapsulates lithium and transition metal ions.

A new macrotricyclic ligand, L3 with an N4S2 donor set that encapsulates lithium and transition metal ions has been synthesized from the tetraazamacrocycle cyclam.

Cobalt Cage Complexes with N(3)S(3) Donor Sets and Differing Cavity Sizes: A Novel Macrobicyclic Cage with a Contracted Cap.

Treatment of the cobalt(III) complex of the hexadentate tripodal N(3)S(3) ligand ten (4,4',4' '-ethylidynetris(3-thiabutan-1-amine) with propanal and paraformaldehyde under basic conditions, followed by borohydride reduction and reoxidation of the metal center, leads largely to the encapsulated (red) metal complex cation [Co(Me(2)-N(3)S(3)sar)](3+) (Me(2)-N(3)S(3)sar = 1,8-dimethyl-3,13,16-trithia-6,10,19-triazabicyclo[6.6.6]icosane).
