The accuracy of eight ultrasonic fetal weight formulas were analyzed in 1099 fetuses who underwent real-time ultrasound examination within 72 hours prior to delivery. Shepard's formula was most consistently found to give the lowest systematic and random errors throughout all weight categories, though Deter's formula had an almost identical accuracy. The(More)
OBJECTIVES The incidence of hepatocellular carcinoma (HCC) seems to be rising in the United States (US), and considerable variability in the incidence and etiology of HCC has been noted among different racial and ethnic groups in this country. The aim of this study was to evaluate the influence of racial and ethnic status in the viral etiology of HCC in the(More)
Five new ultrasonic weight formulae incorporating head circumference, fetal femur length, and a correction for oligohydramnios were prospectively analyzed in a group of 198 unselected patients scanned within 72 hours of birth. Comparison with the Shepard formula showed that inclusion of these parameters slightly, but significantly, improved the random error(More)
Four hundred sixty-four fetuses underwent real time ultrasound examination within 72 hours before birth to evaluate other factors than the weight formula itself that might influence the accuracy of ultrasound weight estimation. The results indicated that fetal sex had no effect on weight estimation accuracy, but that fetal growth patterns, cephalic index,(More)
The extraction of significant cardiac functional parameters such as ejection fraction and wall thickening depends on reliable detection of myocardial contours. However, the manual contour tracing process is cumbersome, time-consuming, and operator-dependent. These limitations have motivated the development of automated segmentation techniques for accurate(More)

1. Alkohol bewirkt am peripheren motorischen nerven in nicht narkotischen Dosen eine langanhaltende konstante Steigerung der Chronaxie (Erregbarkeitsdepression). 2. 0,05% iges Coffein führt zu einer für Stunden bestehenden Erregbarkeitssteigerung. Nach Auswaschung mit Ringer restiert eine irreversible Abnahme der Erregbarkeit. 3. Bei Kombinationsversuchen(More)

Die vergleiehende Bestimmung der Wirksamkeit der ~Narkotika und Lokalani~sthetika auf den peripheren Nerven ist Gegenstand zahlreicher Untersuchungen gewesen. Da die >>Wirksamkeit(< jedoch ein komplexer Wert insbesondere der Intensiti~t und der Geschwindigkeit ist, so lassen sich die Ergebnisse dieser Arbeiten, die vielfach mit sehr verschiedenen(More)
