Vertical transmission of a Drosophila endosymbiont via cooption of the yolk transport and internalization machinery

Bruno Lemaitre, Juan Camilo Paredes Escobar, Jeremy Keith Herren, Fanny Schüpfer

Spiroplasma is a diverse bacterial clade that includes many vertically transmitted insect endosymbionts, including Spiroplasma poulsonii, a natural endosymbiont of Drosophila melanogaster. These bacteria persist in the hemolymph of their adult host and exh ...

Enhancement of Cytotoxicity by Combining Pyrenyl-Dendrimers and Arene Ruthenium Metallacages

Paul Joseph Dyson, Olivier Pierre Zava

Three generations of pyrenyl bis-MPA dendrimers with two different end-groups, acetonide (pyrG) or alcohol (pyr(Gn center dot OH)) (n = 1-3), were synthesized, and the pyrenyl group of the dendritic molecules was encapsulated in the arene ruthenium metalla ...

Thiolato-bridged arene-ruthenium complexes: synthesis, molecular structure, reactivity and anticancer activity of the dinuclear complexes [(arene)2Ru2(SR)2C12]

Paul Joseph Dyson, Olivier Pierre Zava

Treatment of an areneruthenium dichloride dimer with thiols RSH to lead to cationic trithiolato complexes of the type [(arene)2Ru2(SR)3]+ was shown to proceed through the neutral thiolato complexes [(arene)2Ru2(SR)2Cl2], which have been isolated and charac ...

Patterning and shaping the endoderm in vivo and in culture

Anne Grapin-Botton, Marine Marie Kraus

The definitive endoderm (DE) was first defined as the innermost germ layer found in all metazoan embryos. During development, it gives rise to a vast array of specialized epithelial cell types lining the respiratory and digestive systems, and contributes t ...

Encapsulation of Pyrene-Functionalized Poly(benzyl ether) Dendrons into a Water-Soluble Organometallic Cage

Olivier Pierre Zava

Two generations of lipophilic pyrenyl functionalized poly(benzyl ether) dendrimers (P-1 and P-2) have been synthesized. The thermal properties of the two functionalized dendrimers have been investigated, and the pyrenyl group of the dendritic molecules enc ...

Synthesis and anticancer activity of chalcogenide derivatives and platinum(II) and palladium(II) complexes derived from a polar ferrocene phosphanyl-carboxamide

Paul Joseph Dyson, Anna Katherine Renfrew

The polar phosphinyl carboxamide, 1'-(diphenylphosphino)-1-[N-(2-hydroxyethyl)carbamoyl]ferrocene [I; Z = null; (1)] , reacts readily with H2O2 and elemental S to give the corresponding phosphine oxide I [Z = O (2)] and phosphine sulfide I [Z = S (3)], res ...
