[more ▼] Les études des interactions entre la lumière et la matière relèvent du domaine de la physique mais elles ont des implications importantes en chimie et en biologie. Dans cet article, nous présenterons trois exemples, dans lesquels le phénomène de l'absorption lumineuse par certains chromophores et les réactions photochimiques, initiées à partir des différents états excités, constituent les étapes primaires de réactions photobiologiques qui peuvent avoir des conséquences aussi diverses que l'apparition de mutations dans les chromosomes et l'oxydation des constituants de membranes. Ces réactions biologiques sont appelées réactions de photosensibilisation et elles ont des implications importantes dans de nombreux domaines des sciences fondamentales et appliquées.

[more ▼] We report here an in vitro model of neuronal infection by varicella-zoster virus (VZV). Such a model has been achieved by using dissociated adult rat dorsal root ganglia cells infected by cocultivation with VZV-infected MRC5 cells or with cell-free virus. Indirect VZV immunolabeling, in situ hybridization, and neuron-specific immunolabeling demonstrated that VZV infection occurred selectively in neurons. VZV-specific immunolabeling detected a few neurons 1 or 2 days postinfection but not later. Genome detection using cloned VZV DNA probes revealed a hybridization signal primarily with RNA. Within 1 to 6 days postinfection, a progressive increase of VZV-specific hybridization was observed in up to 50% of the neurons. RNAs corresponding to immediate-early, early, and late genes were found, and transcripts of immediate-early gene 63 were particularly abundant.

[more ▼] The quantum yields of singlet oxygen production by merocyanine 540 have been measured during visible light irradiation performed in methanol and ethanol. These appear to be one hundred times smaller than the quantum yield for rose bengal measured under the same conditions. Flash photolysis experiments demonstrate the ability of merocyanine 540 molecules to isomerize under visible light irradiation: the isomerization quantum yields are about 0.65 in both ethanol and methanol. This information combined with the fluorescence quantum yield data account for the low values for singlet oxygen production.
