Cognitive testing with touchscreen-equipped operant boxes (‘touchscreens’) is becoming increasingly popular. Tasks, such as paired associate learning or reversal learning of visual stimuli, have the discrimination of visual stimuli as a fundamental component. However, the effect of drugs commonly used in the study of cognitive mechanisms has yet to be(More)
The proportion of lung cancer due to occupational exposure has been estimated by computing the attributable risk in the population (ARp) from various case-control studies. Different criteria have been used in including occupational exposures from published studies: (i) exposure to lung carcinogens according to a job-exposure matrix approach; (ii)(More)
Remission from depressive illness is associated with a modification in patients' behavioural reactions to environmental/social stimulation, and requires continuous drug treatment. We have examined the effects of antidepressant drug treatment and repeated electroconvulsive shock (ECS) on the behaviour of rats during social interaction (SI) to determine(More)
Job exposure matrices (JEM) are designed to link information on occupation with information on exposure to specific workplace hazards. In spite of some limitations, JEM are particularly useful in large retrospective epidemiological studies. The development of JEM designed for a company or an industrial sector have a more specific field of application than(More)
Nine-hundred-and-twenty-two hypertensive patients were included in a substudy to the Hypertension Optimal Treatment study, which aimed to investigate the impact on quality of life of lowering the pressure and of intensified therapy. Seven-hundred-and-eighty-one patients completed both baseline and follow-up questionnaires (intention-to-treat population),(More)
The aim of this study was to determine whether electroconvulsive shock (ECS, an established antidepressant treatment), like acute and chronic antidepressant drug treatments, produces similar differential effects on the behavioural profile of resident rats expressed during social encounters with unfamiliar intruder conspecifics (resident-intruder paradigm).(More)
A total of 719 lung cancers were identified in a follow-up of 135,000 Swedish construction workers interviewed during 1971-1974 by occupational health nurses as part of a routine health check-up. These were analysed in a matched case-control study nested within this cohort, to compare different methods of characterizing exposure to asbestos. Self-reported(More)
Venlafaxine, a novel 2-phenyl-2-(1-hydroxycycloalkyl) ethylamine, is a potent inhibitor of 5-hydroxytryptamine and noradrenaline reuptake and exhibits a profile of activity in pre-clinical in vitro biochemical studies predictive of antidepressant activity. The studies described here examined the effects of acute and chronic treatment with venlafaxine on the(More)
OBJECTIVES The aim of this study was to determine whether therapy with a beta-adrenergic or calcium channel blocking agent can improve the functional capacity and quality of life of patients with mild or moderately symptomatic hypertrophic cardiomyopathy. BACKGROUND Both beta-blockers and calcium channel blockers may alleviate symptoms in hypertrophic(More)
The study concentrated on 21,967 workers producing rock wool/slag wool, glass wool or continuous filament in 13 European factories. The expected deaths and incident cancer cases were derived from multiplying the accumulated person-years by national reference rates across sex, age, and calendar-year strata, correction factors for regional lung cancer(More)
