This study investigated arsenic and lung cancer incidence in a community setting in the Montreal area. Job histories and sociodemographic factors were collected by interview from 857 lung cancer cases, 533 general population controls, and 1,360 controls with other cancers. Chemist-hygienists assessed each subject's life-time occupational exposure to 294(More)
This investigation concerned the use of quantitative risk assessment for estimating cancer mortality at low-level exposures. We empirically tested whether extrapolating by linear no-threshold models predicted implausible risks at low-level exposures. Cadmium in cigarette smoke was the low-level exposure, and extrapolation was based on potencies estimated(More)
OBJECTIVES This study examined alterations in the functions and proteome of high-density lipoprotein (HDL) subfractions (HDL2 and HDL3) isolated from patients with acute coronary syndrome (ACS) compared with control subjects. METHODS We measured HDL subfraction cholesterol efflux capacity, inflammatory index (HII), paraoxonase-1 (PON1) activity, and lipid(More)
AIM The purpose of this study was to investigate the association between dental caries and obesity in preschool children. MATERIALS AND METHODS A total of 329 preschool children were recruited from nine day care centers. A qualified dentist examined the oral health of each child and a caries score was recorded. Anthropometric measurements included body(More)
OBJECTIVE To investigate the relation of vestibular stimulus induced symptoms to electrogastrogram (EGG), electronystagmogram (ENG), acupoint potential (AP), skin temperature (ST) heart rate variability (HRV) and content of urine hormones. METHOD The physiological parameters were recorded before, during and after vestibular stimuli. Graybiel's scoring(More)
