(author), TNO Kwaliteit van Leven (author)Background: Wet-wrap treatment (WWT) with diluted topical steroids is widely used in atopic dermatitis (AD). Mice with transgenic overexpression of human apolipoprotein C1 (APOC1) in the liver and the skin are not only characterized by hyperlipidaemia and raised IgE levels, but also by pruritic dermatitis and a disturbed skin barrier function,...article 2009

van Ommen, B. (author), Keijer, J. (author), Heil, S.G. (author), Kaput, J. (author), TNO Kwaliteit van Leven (author)A primary goal of nutrition research is to optimize health and prevent or delay disease. Biomarkers to quantify health optimization are needed since many if not most biomarkers are developed for diseases. Quantifying "normal homeostasis" and developing validated biomarkers are formidable tasks because of the robustness of homeostasis and of...article 2009

(author), TNO Kwaliteit van Leven (author)Similar to native cardiovascular tissues, the mechanical properties of engineered cardiovascular constructs depend on the composition and quality of the extracellular matrix, which is a net result of matrix remodeling processes within the tissue. To improve tissue remodeling, and hence tissue mechanical properties, various mechanical...article 2009

(author), TNO Kwaliteit van Leven (author)The human vitreous body undergoes structural changes with aging. This can be followed by a posterior vitreous detachment, which can result in ocular pathology. As in many collagenous tissues, age-related changes in the vitreous could be caused by the formation of advanced glycation end products (AGEs). The goal of this study was to find out...article 2009

(author), TNO Kwaliteit van Leven (author)Background: Infarct rupture is a usually fatal complication of myocardial infarction (MI), for which no molecular mechanism has been described in humans. Experimental evidence in mouse models suggests that the degradation of the extracellular matrix by matrix metalloproteinases (MMPs) plays an important role in infarct rupture. The present study...article 2009
