OBJECTIVES The purpose was to study the effects on the nervous system in welders exposed to aluminium and manganese. METHODS The investigation included questionnaires on symptoms, psychological methods (simple reaction time, finger tapping speed and endurance, digit span, vocabulary, tracking, symbol digit, cylinders, olfactory threshold, Luria-Nebraska(More)
Heart rate, performance, and symptoms were studied in six female and six male volunteers, aged 19 to 47 years, during experimental 2-hr exposures to 10 and to 200 mg/m3 of methyl isobutyl ketone (MIBK). No effects from exposure on performance of a reaction time task or an arithmetic test could be demonstrated, and no consistent effects on heart rate were(More)
Tension of the forehead increases as a response to unpleasant stimuli. In three experiments EMG activity in corrugator muscle was measured to test this response as an indicator of noise annoyance. In Exp. 1 (n = 24) monotonic sound level-response functions were obtained for four levels of 100- and 1000-Hz tones. In Exp. 2 (n = 20) recordings were made(More)
BACKGROUND Periostin (osteoblast-specific factor OSF-2) is a secreted protein occurring in seven known isoforms, and it is involved in a variety of biological processes in osteology, tissue repair, oncology, cardiovascular and respiratory systems or allergic manifestations. To analyze functional aspects of periostin, or the ability of periostin as potential(More)
