    Population differences in S-warfarin pharmacokinetics among African Americans, Asians and whites: their influence on pharmacogenetic dosing algorithms

    Using population pharmacokinetic analysis (PPK), we attempted to identify predictors of S-warfarin clearance (CL(S)) and to clarify population differences in S-warfarin pharmacokinetics among a cohort of 378 Afri...

    Systematic theoretical investigation of a positron binding to amino acid molecules using the ab initio multi-component molecular orbital approach

    The feature of positron binding to twenty neutral amino acid molecules with the global minimum (GM) and intramoleculear hydrogen-bonded (HB) structures was analysed using the ab initio multi-component molecula...

    Dark resonance of Cs atoms velocity-selected in a thin cell

    We carried out experimental and theoretical research on dark Raman resonances in the absorption of the probe monochromatic wave in a thin vapor cell, whose length is much less than the diameters of probe and c...

    Allan-variance measurements of diode laser frequency-stabilized with a thin vapor cell

    A novel method of stabilizing laser frequency that uses a sub-Doppler spectrum of atoms in a thin vapor cell has been developed. The extended-cavity diode laser is frequency-locked to a hyperfine component of ...

    Identification of CAG repeat-containing genes expressed in human brain as candidate genes for autosomal dominant spinocerebellar ataxias and other neurodegenerative diseases

     To obtain novel candidate genes for autosomal dominant spinocerebellar ataxia and other neurodegenerative disorders in which gene mutations remain unidentified, we screened a human fetal brain cDNA library us...

    High-resolution spectroscopy of velocity-selected atoms in a thin cell

    We propose a novel technique of sub-Doppler spectroscopy using a thin vapor cell. Optical pum** in a thin cell transfers atoms with small velocity components to a specific quantum state. The resultant veloci...

    Far-infrared hydrazine laser pumped by an N2O laser

    We have used an N2O laser to optically pump N2H4 molecules in a far-infrared cavity and observed 17 new laser lines in the wavelength range 93.0 to 374.2 µm, the 136.8 µm line pumped by 10P(16) being a doublet. W...

    The effects of salinity on pentachlorophenol accumulation and elimination by killifish (Oryzias latipes)

    Fresh water and seawater acclimated (FWA and SWA) killifish (Oryzias latipes) were exposed to pentachlorophenol (PCP) at various salinities (1.2–18.7‰). The PCP accumulation in the fish decreased with increase of...

    Measurement of rotational temperature in CO2 waveguide laser medium

    A small-signal gain in CO2 waveguide laser medium has been measured on rotational-vibrational transitions in the P-branch of the (0, 0, 1)-(0, 20, 0) band. It has been found that the rotational temperature is wel...

    Undamped undulation superposed on the passive Q-switching pulse of a CO2 laser

    An undamped undulation superposed on the pulse tail of the passive Q-switching is observed using HCOOH gas as a saturable absorber. The pulse shapes with the undulation are nicely reproduced through the rate-e...
