Journal ArticleDOI
The emergence of fetal behaviour. I. Qualitative aspects.
TL;DR: The emergence of spontaneous fetal motility during the first 20 weeks of gestation was studied longitudinally in 11 healthy nulliparae, using real-time ultrasound to study the onset and developmental course of spontaneously generated specific fetal movement patterns.
Journal ArticleDOI
Underlying disorders associated with severe early-onset preeclampsia.
G.A. Dekker,J. de Vries,P.M. Doelitzsch,Peter C. Huijgens,B. M. E. Von Blomberg,C. Jakobs,H.P. van Geijn +6 more
TL;DR: Patients with a history of severe early-onset preeclampsia should be screened for protein S deficiency, activated protein C resistance, hyperhomocysteinemia, and anticardiolipin antibodies, since these results may have an impact on counseling for and pharmacologic management in future pregnancies.
Journal ArticleDOI
Electrochemical and surface characterization of a nickel-titanium alloy.
D. J. Wever,Albert G. Veldhuizen,J. de Vries,Henk J. Busscher,Donald R. A. Uges,J.R. van Horn +5 more
TL;DR: It is suggested that the good corrosion properties of the NiTi alloy and the related promising biological response, as reported in literature, may be ascribed to the presence of mainly a TiO2-based surface layer and its specific properties, including the formation of a calcium-phosphate layer after exposure to a bioenvironment.
Journal ArticleDOI
The Timed "up and go" test: reliability and validity in persons with unilateral lower limb amputation.
TL;DR: The Timed "up and go" test is a reliable instrument with adequate concurrent validity to measure the physical mobility of patients with an amputation of the lower extremity.
Journal ArticleDOI
Severe maternal morbidity during pregnancy, delivery and puerperium in the Netherlands: a nationwide population-based study of 371,000 pregnancies.
TL;DR: Assessment of incidence, case fatality rate, risk factors and substandard care in severe maternal morbidity in the Netherlands finds that women with a history of maternal disease are more likely to die than those with a clean bill of health.
