Twin pregnancies provide us with the opportunity to observe first reactions towards touch in utero, and this study illustrates the onset and development of these contacts. Forty women with twin pregnancies volunteered to take part in this study, 25 of whom (five monochorionic, 20 dichorionic pairs) fulfilled the inclusion criteria. Between 8 and 12 weeks'(More)
One hundred and three intrauterine growth retardation (IUGR) pregnancies were scheduled for pulsed Doppler ultrasound of the common carotid and the umbilical artery, nonstress and contraction stress tests (NST/CST) as well as vibroacoustic stimulation tests (VAST). The last examinations < 3 days before birth were compared by receiver-operator(More)
The astroglia cytoskeletal element, glial fibrillary acid protein GFAP, is a generally accepted sensitive indicator for neurotoxic effects in the mature brain. We used GFAP RNA as a marker for molecular biological changes in rat brain related to chronic low level lead exposure during the developmental period. Brains in the third week of postnatal life,(More)
This study was undertaken to determine the effects of superimposing incremental levels of positive end-expiratory pressure (PEEP) during partial liquid ventilation (PLV) on gas exchange, respiratory mechanics and morphological changes in experimental acute lung injury (ALI). In a prospective trial, six pigs weighing 30+/-5 kg (mean+/-SD) were(More)
In 1992 blood samples were taken from 630 forestry workers in the state of Brandenburg, Germany, and an inquiry about tick bites and possible symptoms of Lyme borreliosis carried out in order to determine the seroprevalence of the disease. To estimate the rate of seroconversion within six months, 406 of the individuals were investigated a second time. IgG(More)
OBJECTIVE Our purpose was to define the diagnostic value of a new fetal assessment score that is based on each of the components of the Apgar score. STUDY DESIGN A fetal assessment score was established to study the main fetal vital functions: (1) cardiovascular (heart rate, color of the skin in the Apgar score), now based on fetal heart rate patterns and(More)
Radioimmunoassays of human placental lactogen and estriol levels in the maternal plasma, ultrasound biometry of the abdominal diameter (AD), pulsed Doppler measurements of uteroplacental arteries, the common carotid artery (CCA), and the umbilical artery (UA) and fetal heart rate monitoring were simultaneously performed in 219 risk pregnancies from 26(More)
The objective of this study was to determine the feasibility and clinical impact of hepatic venous oxygenation monitoring in patients undergoing positive end-expiratory pressure (PEEP) ventilation after OLT. The design comprised a prospective study using repeated-measures design, within an intensive-care unit for liver-transplanted patients in a university(More)
This paper discusses results of a computer simulation for designing a new pulse duplicator system for mechanical heart valves. The design objective of the system is to obtain a compact, efficient pulse duplicator system capable of accurately measuring the volume flow rate across a valve. The volume flow rate is determined as the derivative of the volume(More)
