    UGT1A and UGT2B genetic variation alters nicotine and nitrosamine glucuronidation in European and African American smokers (review)
    with C. A. Wassenaar, D. V. Conti, S. Das, E. H. Cook, M. J. Ratain, N. L. Benowitz, and R. F. Tyndale
    © 2014 American Association for Cancer Research.Background: Identifying sources of variation in the nicotine and nitrosamine metabolic inactivation pathways is important to understanding the relationship between smoking and cancer risk. Numerous UGT1A and UGT2B enzymes are implicated in nicotine and nitrosamine metabolism in vitro; however, little is known about their roles in vivo. Methods: Within UGT1A1, UGT1A4, UGT1A9, UGT2B7, UGT2B10, and UGT2B17, 47 variants were genotyped, including UGT2B1…Read more

    © The Author 2016.Charge density wave formation, a key physics issue for materials, arises from interactions among electrons and phonons that can also lead to superconductivity and other competing or entangled phases. The prototypical system TiSe 2, with a particularly simple transition and no Kohn anomalies caused by electron-phonon coupling, is a fascinating but unsolved case after decades of research. Our angle-resolved photoemission measurements of the band structure as a function of tempera…Read more

    Dimensional Effects on the Charge Density Waves in Ultrathin Films of TiSe 2
    with Y. H. Chan, M. H. Wong, X. Y. Fang, M. Y. Chou, S. K. Mo, Z. Hussain, A. V. Fedorov, and T. C. Chiang
    © 2016 American Chemical Society.Charge density wave formation in solids is a critical phenomenon involving the collective reorganization of the electrons and atoms in the system into a wave structure, and it is expected to be sensitive to the geometric constraint of the system at the nanoscale. Here, we study the CDW transition in TiSe2, a quasi-two-dimensional layered material, to determine the effects of quantum confinement and changing dimensions in films ranging from a single layer to multi…Read more
