Swart, P. (author), Lozac'h, F. (author), Simon, M. (author), van Duijn, E. (author), Vaes, W.H. (author)Modern accelerator mass spectrometry (AMS) methods enable the routine application of this technology in drug development. By the administration of a (14)C-labelled microdose or microtrace, pharmacokinetic (PK) data, such as mass balance, metabolite profiling, and absolute bioavailability (AB) data, can be generated easier, faster, and at lower...article 2016

Kong, G. (author), Alais, D. (author), van der Burg, E.D. (author)In the present study, we examine how observers search among complex displays. Participants were asked to search for a big red horizontal line among 119 distractor lines of various sizes, orientations and colours, leading to 36 different feature combinations. To understand how people search in such a heterogeneous display, we evolved the search...article 2016

Bernaards, C. (author), Hildebrandt, V.H. (author), Hendriksen, I.J. (author)Background. Evidence shows that prolonged sitting is associated with an increased risk of mortality, independent of physical activity (PA). The aim of the study was to identify correlates of sedentary time (ST) in different age groups and day types (i.e. school-/work day versus non-school-/non-work day). Methods. The study sample consisted of...article 2016
