  • Platelet Serotonin Signaling in Patients With Cardiovascular Disease and Comorbid Depression

    Marlene S Williams, Roy C Ziegelstein et al.ARTICLEPsychosomatic Medicine2019

    OBJECTIVE: Depression in patients with cardiovascular disease is associated with increased risk of adverse clinical outcomes. Investigators have searched for potential biobehavioral explanations for this increased risk. Platelet activation and response to serotonin is an attractive potential mechanism. The aim of the study was to examine platelet serotonin signaling in a group of patients with coronary artery disease (CAD) and comorbid depression…

  • Ethnic, Geographic, and Genetic Differences in Arsenic Metabolism at Low Arsenic Exposure

    Open AccessPoojitha Balakrishnan, Miranda R Jones et al.ARTICLEInternational Journal of…2018

    We investigated the effect of candidate variants in AS3MT (arsenic (III) methyltransferase) with urinary arsenic metabolites and their principal components in a subset of 264 participants in the Multi-Ethnic Study of Atherosclerosis (MESA). Urinary arsenic species, including inorganic arsenic (iAs), monomethylarsonate (MMA), dimethylarsinate (DMA), and arsenobetaine (Ab), were measured using high performance liquid chromatography-inductively coup…

  • Association of Geography and Ambient Air Pollution with Urine Metal Concentrations in Six US Cities

    Open AccessYuanjie Pang, Miranda R Jones et al.ARTICLEInternational Journal of…2016

    We investigated the associations of urinary concentrations of antimony, cadmium, tungsten and uranium with geographic locations and with ambient air pollution in 304 adults in the Multi-Ethnic Study of Atherosclerosis from six US cities. After adjustment for sociodemographics, body mass index, and smoking status, urinary cadmium was the highest in Winston-Salem among all study sites (the geometric mean [GM] in Winston-Salem was 0.84 μg/L [95% con…

  • Impact of Self-Preference Community Fitness Interventions in High-Risk African Americans

    Lisa R Yanek, Dhananjay Vaidya et al.ARTICLEFamily & Community Health2016

    African Americans have a high prevalence of obesity and physical inactivity, but few interventions have been successful in the long term. We describe a 1-year intervention program to increase physical activity and reduce cardiometabolic risk. Interventions incorporated the premise that self-selection into flexible venues and varying exercise modalities would result in improvement in fitness and risk factors. Results of this single-group pretest/p…

  • A Test of Biological and Behavioral Explanations for Gender Differences in Telomere Length

    B L Needham, Ana V Diez Roux et al.ARTICLEBiodemography and Social Biology2014Cited by: 6References: 68

    The purpose of this study was to examine biological and behavioral explanations for gender differences in leukocyte telomere length (LTL), a biomarker of cell aging that has been hypothesized to contribute to women's greater longevity. Data are from a subsample (n = 851) of the Multi-Ethnic Study of Atherosclerosis, a population-based study of women and men aged 45 to 84. Mediation models were used to examine study hypotheses. We found that women…
