(author), TNO Kwaliteit van Leven (author)β1 integrins play a controversial role during chondrogenesis. Since the maturation of chondrocytes relies on a signaling switch from cell-cell to cell-matrix interactions, we hypothesized that β1 integrins play a different role at the earlier (mainly cell-cell interaction) from the later stage (mainly cell-matrix interaction) of chondrogenesis....article 2008

(author), TNO Kwaliteit van Leven (author)Obese humans are often insulin- and leptin resistant. Since leptin can affect glucose metabolism, it is conceivable that a lack of leptin signal transduction contributes to insulin resistance. It remains unclear whether leptin affects glucose metabolism via peripheral and/or central mechanistic routes. In the present study, we aimed: (i) to...article 2008

(author), TNO Kwaliteit van Leven (author)Polyunsaturated fatty acids, including docosahexaenoic acid (DHA), are natural constituents of the human diet. DHA-algal oil is produced through the use of the marine protist, Ulkenia sp. The reproductive toxicity of DHA-algal oil was assessed in a one-generation study. Rats were provided diets containing DHA-algal oil at concentrations of 1.5,...article 2007
