de Bie, A.T.H.J. (author), van Ommen, B. (author), Bär, A. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)The absorption, disposition, metabolism, and excretion of 14C-labeled γ-cyclodextrin ([14C]γ-CD) was examined in four separate experiments with Wistar rats. In experiment 1, [14C]γ-CD (25 μCi, 600 mg/kg body wt) was administered intravenously to four male and four female conventional rats. In experiment 2, [14C]γ- CD (25 μCi, 1000 mg/kg body wt)...article 1998

van den Heuvel, E.G.H.M. (author), Muijs, T. (author), van Dokkum, W. (author), Schaafsma, G. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)Animal studies have indicated that calcium absorption is increased by lactulose, a synthetic disaccharide. Therefore, the influence of lactulose on calcium absorption was measured in postmenopausal women who may benefit from the possible enhancing effect of lactulose on calcium absorption. Twelve postmenopausal women drank 100 ml of water...article 1999

van den Heuvel, E.G.H.M. (author), Schoterman, M.H.C. (author), Muijs, T. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)The aim of this study was to investigate whether a product rich in transgalactooligosaccharides (TOS, Elix'or) stimulates true Ca absorption in postmenopausal women. The study was a double-blind, randomized crossover study, consisting of two 9-d treatment periods separated by a 19-d washout period. During the treatment periods, 12 subjects drank...article 2000

(author), van Leeuwen, J.P.T.M. (author), Hazewinkel, H.A.W. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)Hormonal regulation of calcium (Ca) absorption was investigated in a cholecalciferol (vitamin D3)supplemented group (hVitD) vs. a control group (cVitD) of growing Great Danes (100 vs. 12.5 μg vitamin D3/kg diet). Although Ca intakes did not differ, fractional Ca absorption was significantly lower in the hVitD group than in the cVitD group. There...article 2002
