Anticoagulation with vitamin K antagonists (VKAs) is problematic because of difficulties in safely managing dosing. Polymorphisms in cytochrome P450 2C9 (CYP2C9) and vitamin K epoxide reductase genes (VKORC1) have been shown to affect VKA dosing in adults. The association of these polymorphisms on VKA dosing in children has not been investigated. The(More)
OBJECTIVES Age-related changes in the hemostatic system result in variation in response to anticoagulants and coagulation assays over childhood. This study used in vitro methods to determine i) optimum coagulation assays for dabigatran in children and ii) anticoagulant effect of dabigatran across pediatric age groups. MATERIALS AND METHODS Pooled plasma(More)
INTRODUCTION Pediatric oncology patients are at increased risk for deep venous thrombosis (DVT). Determining the sub-population of children at increased DVT risk is critical for optimum clinical management. Therefore, the aim of the current study was to identify clinical risk factors for DVT which are easily identifiable at cancer diagnosis. MATERIALS AND(More)
To determine whether PAX-2 and PAX-8 are involved in Wilms tumor (WT) pathogenesis, we sought mutations in these two genes in 99 Wilms tumors of favorable histology. We screened the entire protein coding sequences as well as the intronic regions adjacent to exons, using denaturing HPLC followed by sequencing of samples displaying abnormal chromatograms. In(More)
We have analyzed the short arm of chromosome 1 using loss of heterozygosity (LOH) analysis in Wilms tumors (WT) to identify a minimal region of loss. 1909 WT, 22 malignant rhabdoid tumors of the kidney and 90 clear cell carcinomas of the kidney (CCSK) were subjected to LOH analysis using five markers flanked by D1S243 and D1S244. 225 WT and 4 CCSK displayed(More)
Obesity in adolescents increases their risk for deep vein thrombosis. The objectives of this study were to determine potential mechanisms for thrombotic risk by investigating the fibrinolytic pathway in a sample of adolescents with and without obesity. Thirty-seven adolescents with obesity and 16 normal weight age-matched controls were recruited. Plasma(More)
Diese Arbeit widmet sich der Erstellung eines Models für einen Named Entity Recognizer (NER) zum Erkennen von Entitäten aus eBay-Auktionstiteln. Der Fokus liegt dabei auf Auktionen in der Kategorie ,,Handys ohne Vertrag“. Endergebnis ist ein three-class-model, das aus vorgegebenen Auktionstiteln die drei Entitäten BRAND, COLOR und STORAGE erkennt und(More)
