Sex hormone-binding globulin (SHBG) is a glycoprotein responsible for the transport and biologic availability of sex steroid hormones, primarily testosterone and estradiol. SHBG has been associated with chronic diseases including type 2 diabetes (T2D) and with hormone-sensitive cancers such as breast and prostate cancer. We performed a genome-wide(More)
Only one prior study has examined why adolescent smoking cessation interventions are effective. To address this understudied and important issue, we examined whether a large adolescent smoking cessation intervention trial's outcomes were mediated by social cognitive theory processes. In a randomized trial (N = 2,151), counselors proactively delivered a(More)
Sedentary behavior is associated with deleterious health outcomes. This study evaluated the association between sedentary time and physical function among postmenopausal women in the Women's Health Initiative Observational Study. Data for this prospective cohort study were collected between 1993-1998 (enrollment) and 2009, with an average of 12.3 follow-up(More)
OBJECTIVE To test whether estrogen receptor polymorphisms modify the effects of postmenopausal hormone therapy on biomarkers and on risk of coronary heart disease events, stroke, or venous thromboembolism. METHODS AND RESULTS The design was a nested case-control study in the Women's Health Initiative trials of postmenopausal hormone therapy. The study(More)
OBJECTIVE To investigate the influence of common and low-frequency genetic variants on the risk of ischemic stroke (all IS) and etiologic stroke subtypes. METHODS We meta-analyzed 12 individual genome-wide association studies comprising 10,307 cases and 19,326 controls imputed to the 1000 Genomes (1 KG) phase I reference panel. We selected variants(More)
BACKGROUND The purpose of this study was to describe the longitudinal trajectories and bidirectional relationships of the physical-social and emotional functioning (EF) dimensions of positive aging and to identify their baseline characteristics. METHODS Women age 65 and older who enrolled in one or more Women's Health Initiative clinical trials (WHI CTs)(More)
BACKGROUND The consumption and blood concentrations of lycopene are both positively and inversely associated with the risk of several chronic diseases. The inconsistences in lycopene disease association studies may stem from a lack of knowledge about the genetic variation in the synthesis, metabolism, and deposition of transport and binding proteins, which(More)
OBJECTIVE A 10-year follow-up study to test the extent to which theory-based adolescent psychological and social factors directly predict and moderate the prediction of young adult smoking acquisition and cessation. DESIGN A prospective community-based sample. A total of 2,970 adolescents participated in the large Washington State Hutchinson Smoking(More)
Topological insulators (TIs), are novel two-dimension materials, which can act as effective saturable absorbers (SAs) in a fiber laser. Moreover, based on the evanescent wave interaction, deposition of the TI on microfiber would create an effective SA, which has combined advantages from the strong nonlinear optical response in TI material together with the(More)
