Human amniotic fluid cells (H-AFC) have been used as a diagnostic tool for the prenatal diagnosis of fetal genetic anomalies for more than 50 years.In the early 1990s small nucleated cells, which were identified as he-matopoietic progenitors, were detected in the amniotic fluid. After this evidence several other scient…

The (230)Th ages and (234)U/(238)U ratios were determined for Barbados corals that grew during periods of high sea level within the last 200,000 years. The similarity of the initial (234)U/(238)U ratios of some of the corals to the modern marine value suggests that these samples are pristine and that the marine (234)U/…

Abdominal packing and planned reoperation is a lifesaving technique for temporary control of haemorrhage in severely injured patients. Morbidity and mortality, however, remain significant. The purpose of this study is to evaluate all surgical technique and our results during 31 years of trauma surgery. In the last 12 y…

The magnitude of atmospheric cooling during the Last Glacial Maximum and the timing of the transition into the current interglacial period remain poorly constrained in tropical regions, partly because of a lack of suitable climate records. Glacial moraines provide a method of reconstructing past temperatures, but they…

This work presents a first estimation of the sedimentation rate for the Red Lake (Romania). The sediment accumulation rates were determined by two well-known methods for recent sediment dating: (210)Pb and (137)Cs methods. Both techniques implied used the gamma emission of the above-mentioned radionuclides. The (210)Pb…

Febrile children of both sexes, aged between 0-15 years coming to the Civil Hospital over the last 12 years had their blood tested for malarial parasite. Five hundred and twenty-six slides positive for Plasmodium were analysed for species and stage identification. Of the total 59.3% children with malaria were between 5…

We present the clinical characteristics of 14 children with congenital pseudarthrosis of the tibia (CPT) treated in northern Finland at Oulu University Hospital during the years 1968-1996. The incidence of CPT in northern Finland was 3.5/10(5) during years 1962-1996, which is higher than in previous reports. The estima…

The records of patients who received an artificial urinary sphincter at the University of Minnesota were reviewed. A total of 19 patients fulfilled the following criteria: male gender, neurogenic sphincteric incompetence, no previous surgery on the bladder neck, myelodysplasia and more than 5 years of followup. Mean ag…

A series of 189 consecutive posterior cruciate condylar total knee arthroplasties (TKAs) in 151 patients was reviewed. Of these, 18 patients died (22 knees), and two patients (three knees) were lost to follow-up study, leaving 164 knees in 131 patients for evaluation at 5.3 +/- 0.8 years (mean +/- SD). Before surgery 9…

We evaluated whether the results of diagnostic polymerase chain reaction (PCR) testing combined with time since last vaccine dose could be used to monitor the effectiveness of acellular pertussis vaccines. In 258 consecutive nasopharyngeal swabs from children and adolescents with typical pertussis symptoms, 80 were pos…
