BACKGROUND Although rates of tobacco use and exposure to second-hand smoke (SHS) are declining in Canada, SHS exposure among non-smoking adolescents remains high. This study aimed to describe frequency, locations, and avoidance behavior related to SHS exposure among adolescent girls in British Columbia, Canada. METHODS Data were analyzed from 841 adolescent girls aged 13 to 15 years old who c...

The present study integrates the work environment hypothesis and effort-reward imbalance model to argue that work-related antecedents of workplace bullying are moderated by day-to-day leadership practices one’s immediate leader. Specifically, we propose individuals’ daily experiences pressure positively related their bullying-related negative acts. Moreover, claim this relationship is weaker on...

OBJECTIVES Suicide rates have widely been reported to peak in spring and summer. A frequent hypothesis is that increased sunlight exposure alters biological mechanisms. However, few attempts have been made to systematically untangle the putative suicidogenic risk of sunlight exposure from that of seasonality. We examined whether average hours of daily sunlight in a month confer additional risk ...

BACKGROUND Exposure to electromagnetic field (EMF) emitted by mobile phone and other machineries concerns half the world's population and raises the problem of their impact on human health. The present study aims to explore the effects of electromagnetic field exposures on sleep quality and sleep duration among workers from electric power plant. METHODS A cross-sectional study was conducted i...

statement of problem: since the fluoride releases from materials with the property of releasing fluoride are decreasing gradually, it seems that probably the material rechargeability is more important than their long-term fluoride release. purpose: the objective of this study was to asses the fluoride release and rechargeability of 2 types of fluoride releasing restorative materials, a resin mo...

BACKGROUND To investigate whether light exposure was associated with objectively measured physical activity (PA) and sedentary behaviour in young people. METHODS Participants (n=229, 46.7% female) were young people (mean 8.8 years [SD±2.2]) from the borough of Camden, UK. Daily sedentary time, moderate and vigorous PA (MVPA) and light exposure were measured using a tri-axial accelerometer wit...

AIMS Previously, a retrospective cohort study found no increased risk of acute pancreatitis with current or recent use of exenatide twice daily compared with use of other anti-diabetic drugs. This follow-up study investigated incident acute pancreatitis, with the use of a different data source and analytic method, in patients exposed to exenatide twice daily compared with patients exposed to ot...

Stressors encountered in daily life, such as family arguments or work deadlines, may play an important role in individual health and well-being. This article presents a framework for understanding how characteristics of individuals and their environments limit or increase exposure and reactivity to daily stressors. Research on daily stressors has benefited from diary methods that obtain repeate...

This two-sequence, three-period crossover study is the first pharmacokinetic (PK) study to compare all three innovator formulations of tacrolimus (twice-daily immediate-release tacrolimus capsules [IR-Tac]; once-daily extended-release tacrolimus capsules [ER-Tac]; novel once-daily tacrolimus tablets [LCPT]). Stable renal transplant patients were dosed with each drug for 7 days, and blood sample...

We evaluated the sensitivity and dose dependency of radiation-induced injury in hematopoietic stem/progenitor cells. Adult C57BL/6 mice were daily exposed to 0, 2, 10, 50, and 250 mGy γ-ray for 1 month in succession, respectively. The damage of hematopoietic stem/progenitor cells in bone marrow were investigated within 2 hours (acute phase) or at 3 months (chronic phase) after the last exposure...
