The objective of this study was to cross-calibrate measurements of body composition by dual-energy X-ray absorptiometry (DXA) with chemical analysis of carcasses of pigs in the pediatric range of body weight. Eighteen pigs (25.5 +/- 7.0 kg; 9.9-32.8% body fat) were scanned in duplicate by using DXA with a Lunar DPX-L densitometer in the pediatric medium and adult fast-detail scan modes. Pigs we...

OBJECTIVES A prospective analysis was conducted to define the incidence of occult pneumothorax (OPX), delayed pneumothorax (DPX) and delayed hemothorax (DHX) and to propose an algorithm for surveillance. METHODS During the last 2 years 709 consecutive patients who did not fulfill the indications for intrahospital management were examined at our emergency department for blunt thoracic injury. ...

Precision error of dual-energy X-ray absorptiometry exceeds the expected annual rate of bone loss in the elderly. The capacity to detect changes in areal bone mineral density (aBMD; g/cm(2)) over a 5-yr period was assessed. Six hundred ninety-one women, 75.2 (0.1)yr, from the Malmö OPRA-study, were measured using Lunar DPX-L (GE Lunar, Madison, WI), and 211 men, 74.7 (3.2)yr, from the Malmö Mr ...

Formaldehyde (FA) is known to be genotoxic and mutagenic in proliferating mammalian cells in vitro. The present study was performed to further characterize its genotoxic potential in the V79 Chinese hamster cell line. The induction of DNA strand breaks and DNA-protein cross-links (DPXs) was measured by the comet assay in relationship to the induction of sister chromatid exchanges (SCEs) and mic...
