Journal of vascular surgery, Volume 50, Issue 2, 1 1 2009, Pages 407-412 Fluoroscopic Roentgen stereophotogrammetric analysis (FRSA) to study three-dimensional stent graft dynamics. Koning OH, Kaptein BL, van der Vijver R, Dias NV, Malina M, Schalij MJ, Valstar ER, van Bockel JH

We report the clinical feasibility of fluoroscopic Roentgen stereophotogrammetric analysis (FRSA), a validated method to quantify real time three-dimensional (3D) dynamic motion of stent grafts and the first clinical results after abdominal and thoracic endovascular repair (EVAR). Stent graft motion was measured at 30 (stereo) frames per second, during the cardiac cycle and in the patient after abdominal EVAR, due to respiratory action. Translational motions of the center of mass, diameter chang... Abstract

Animal cognition, Volume 13, Issue 1, 24 4 2009, Pages 1-19 Cognitive consequences of cooperative breeding in primates? Burkart JM, van Schaik CP

Several hypotheses propose that cooperative breeding leads to increased cognitive performance, in both nonhuman and human primates, but systematic evidence for such a relationship is missing. A causal link might exist because motivational and cognitive processes necessary for the execution and coordination of helping behaviors could also favor cognitive performance in contexts not directly related to caregiving. In callitrichids, which among primates rely most strongly on cooperative breeding, t... Abstract

The American journal of cardiology, Volume 104, Issue 6, 21 3 2009, Pages 758-763 Relation between Framingham risk categories and the presence of functionally relevant coronary lesions as determined on multislice computed tomography and stress testing. Nucifora G, Schuijf JD, van Werkhoven JM, Djaberi R, van der Wall EE, de Roos A, Scholte AJ, Schalij MJ, Jukema JW, Bax JJ

Noninvasive assessment of subclinical atherosclerosis by multislice computed tomographic (MSCT) coronary angiography and demonstration of significant, flow-limiting coronary artery disease (CAD) by stress testing may improve patients' risk stratification. However, data relating the complementary information provided by these noninvasive techniques to traditional risk assessment are scarce. In 255 subjects (45% women, mean age 54 +/- 12 years) without known CAD, 64-slice MSCT coronary angiog... Abstract

Infection and immunity, Volume 77, Issue 10, 20 3 2009, Pages 4275-4283 Burkholderia pseudomallei isocitrate lyase is a persistence factor in pulmonary melioidosis: implications for the development of isocitrate lyase inhibitors as novel antimicrobials. van Schaik EJ, Tom M, Woods DE

Burkholderia pseudomallei, the causative agent of melioidosis, has often been called the great "mimicker," and clinical disease due to this organism may include acute, chronic, and latent pulmonary infections. Interestingly, chronic pulmonary melioidosis is often mistaken for tuberculosis, and this can have significant consequences, as the treatments for these two infections are radically different. The recurrent misdiagnosis of melioidosis for tuberculosis has caused many to speculate... Abstract
