Risk assessment of silicosis and lung cancer among construction workers exposed to respirable quartzTNO Kwaliteit van Leven TNO Voeding (author), Tjoe Nij, E. (author), Heederik, D. (author)Objectives: The aim of this study was to assess the magnitude of the silicosis and cancer risk among construction workers. Methods: In 1998, 1335 of 4173 invited construction workers with expected high cumulative exposure to quartz were studied for early signs of silicosis. In 2002 the study was repeated for 96 persons. Exposure measurements...article 2005

(author)Background: Betaine (trimethylglycine) lowers plasma homocysteine, a possible risk factor for cardiovascular disease. However, studies in renal patients and in obese individuals who are on a weight-loss diet suggest that betaine supplementation raises blood cholesterol; data in healthy individuals are lacking. Such an effect on cholesterol would...article 2005

Groen, E.L. (author), Bles, W. (author), TNO Technische Menskunde (author)We examined to what extent body tilt may augment the perception of visually simulated linear self acceleration. Fourteen subjects judged visual motion profiles of fore-aft motion at four different frequencies between 0.04-0.33 Hz, and at three different acceleration amplitudes (0.44, 0.88 and 1.76 m/s2). Simultaneously, subjects were tilted...article 2004
