    Notes: Renormalization effects of the bath-induced vibronic population transfer on resonant light scattering (RLS) from molecules in condensed phases are theoretically studied based on the Markoffian master equation approach. By using the double space diagram technique, the self-energy originated from the bath-induced vibronic population transfer is analytically solved, and the analytic expressions for the intensities both of the stationary and of the time-resolved RLS spectra are derived. The renormalization effect is analyzed in terms of dimensionless molecular parameters, and model calculations are also performed to confirm theoretical results.

    Band structure of stationary emission spectra from a three-level molecule pumped by strong radiation fields (1990)

    Notes: A theory of the emission spectrum from a multilevel molecular system pumped by strong resonant radiation fields based on the double space theory of the density matrix is developed. We are especially concerned with a three-level, one-laser system, and a three-level, two-laser system. It is shown that the band structure cannot always be estimated by the energy level structure of the dressed states. In fact, in both model systems, triplet structures of the emission spectra can be observed in the case where the magnitude of the molecule-field interaction is larger than that of the detuning. The characteristic features of the band structure are interpreted in terms of the dressed state picture based on analytically solvable models. Several numerical calculations are performed to show how the multiplet band structure in the emission spectrum is influenced by the detuning and the power of the pump field(s).

    Suppressive effects of interferons on the production and release of human T-lymphotropic virus type-I (HTLV-I) (1990)

    Notes: Summary The effects of human α-, β-, or γ-interferon (IFN) on the replication and production of human T-lymphotrophic virus type-I (HTLV-I) were investigated in a human T-cell line, MT-2. Virus transmission and production estimated by syncytium formation and HTLV-I-associated reverse transcriptase (RT) activity were strongly suppressed in the presence of α- and β-IFN, but not γ-IFN. However, the expression of virus specific proteins gp46 but not p19, p24, p28, p36, and gp68 was affected with IFNs as revealed by Western blotting analysis. Electron microscopic observations showed that some of the HTLV-I particles were trapped in the intracellular vacuoles in the presence of high doses of α- or β-IFN. Continuous supply of IFNs appeared to be essential for the constant suppression of RT activity. These results suggest that α- and β-IFN do not inhibit HTLV-I gene expression strikingly but suppress processing or assembly of virus proteins and/or releasing of virions in the late phase of maturation.
