van Dieën, J.H. (author), Putten, E.P. (author), Kingma, I. (author), de Looze, M.P. (author), TNO Kwaliteit van Leven (author)This study was designed to determine whether trunk extensor fatigue occurs during low-level activity and whether this is associated with a drop in muscle tissue oxygenation. Electromyography (EMG) feedback was used to impose constant activity in a part of the trunk extensor muscles. We hypothesized that electromyographic manifestations of...article 2009

(author)Background-Doxycycline has been shown to effectively inhibit aneurysm formation in animal models of abdominal aortic aneurysm. Although this effect is ascribed to matrix metalloproteinase-9 inhibition, such an effect is unclear in human studies. We reevaluated the effect of doxycycline on aortic wall protease content in a inical trial and found...article 2009

(author), TNO Kwaliteit van Leven (author)Diabetes mellitus (DM) is a strong predictor of in-stent restenosis. This may be due to a higher level of vascular inflammation. We hypothesized that diabetic patients will benefit from dexamethasone-eluting stents, since local inflammation and consequently neointimal growth are suppressed and no systemic side effects will occur. Methods: 21...article 2008
