(author), TNO Voeding Centraal Instituut voor Voedingsonderzoek TNO (author)We recently described patients with soybean allergy mainly mediated by cross-reactivity to birch pollen allergens. A majority of those patients were reported to have peanut allergy. We sought to study the occurrence of peanut allergy in patients allergic to birch pollen and characterized the Bet v 1-homologous peanut allergen Ara h 8....article 2004

de Wijk, R.A. (author), Prinz, J.F. (author), Engelen, L. (author), Weenen, H. (author), TNO Voeding (author)The role of salivary α-amylase in odour, flavour, and oral texture sensations was investigated in two studies in which the activity of salivary amylase present in the mouth of human subjects was either increased by presenting custards with added α-amylase or decreased by presenting custards with added acarbose, an amylase inhibitor. For starch...article 2004

(author), TNO Kwaliteit van Leven (author)Characterizing school health promotion is its category-by-category approach, in which each separate health-related behavior is addressed independently. Such an approach creates a risk that extra-curricular activities become overloaded, and that teaching staff are distracted by continuous innovations.

(author), TNO Kwaliteit van Leven (author)Background: The brain plays a crucial role in the decision to eat, integrating multiple hormonal and neural signals. A key factor controlling food intake is selective satiety, ie, the phenomenon that the motivation to eat more of a food decreases more than does the motivation to eat foods not eaten. Objective: We investigated the effect of...article 2006

(author), TNO Kwaliteit van Leven (author)It has recently become evident that at least five ceramidase (CDase) isoforms are present in human epidermis, and that specifically acidic CDase (aCDase) and alkaline CDase (alkCDase) activities increase during keratinocyte differentiation, and thus might play a pivotal role(s) in permeability barrier function.
