CONTEXT Methamphetamine abuse is associated with high rates of aggression but few studies have addressed the contributing neurobiological factors. OBJECTIVE To quantify aggression, investigate function in the amygdala and prefrontal cortex, and assess relationships between brain function and behavior in methamphetamine-dependent individuals. DESIGN In a case-control study, aggression and br...

BACKGROUND Despite the plethora of research examining the physical activity-adiposity relation in youth, questions remain regarding the ideal intensity. Therefore, the purpose of this study was to explore the independent effects of physical activity intensity and incidental movement on total and trunk adiposity. METHODS The sample consisted of 1165 youth aged 8 to 17 years from the 2003-04 U....

People find it easier to learn about topics that interest them, but little is known about the mechanisms by which intrinsic motivational states affect learning. We used functional magnetic resonance imaging to investigate how curiosity (intrinsic motivation to learn) influences memory. In both immediate and one-day-delayed memory tests, participants showed improved memory for information that t...

PURPOSE The primary aim was to determine whether incidental physical activity (IPA), expressed either as duration or intensity, was associated with cardiorespiratory fitness (CRF). METHODS Participants were inactive abdominally obese men (n = 43, waist circumference ≥ 102 cm) and women (n = 92, waist circumference ≥ 88 cm) recruited from Kingston, Canada. IPA (>100 counts per minute) was dete...

We report the case of a supraclinoid carotid rupture during the delivery of a balloon-expandable stent in a 59-year-old patient with incidental paraclinoid berry aneurysms for whom stent-assisted coiling was planned. The deployment of the stent resulted in immediate rupture of the artery. We describe the emergent management of this complication with prolonged balloon inflation to occlude the si...

BACKGROUND Interventions designed to increase workplace physical activity may not automatically reduce high volumes of sitting, a behaviour independently linked to chronic diseases such as obesity and type II diabetes. This study compared the impact two different walking strategies had on step counts and reported sitting times. METHODS Participants were white-collar university employees (n = ...

This article reports on a longitudinal study the impact of reading mode incidental collocation learning and predictors gains. The experiment lasted 11 weeks involved 118 Vietnamese EFL learners who were assigned to an experimental group no-treatment control group. encountered 32 target collocations in three graded readers modes: reading-while-listening, with textual input enhancement (i.e., und...
