We present an algorithm to generate a cell-and-portal decomposition of general indoor scenes. The method is an adaptation of the 3D watershed transform, computed on a distance-to-geometry sampled field. The watershed is processed using a flooding analogy in the distance field space. Flooding originates from local minima, each minimum producing a region.(More)
The application of regional cerebral blood flow (rCBF) study by means of lipophilic radiotracers and single photon emission computed (SPECT) devices in very young infants is hampered by the considerable changes of rCBF pattern as a result of the cerebral maturation process. In an attempt to determine the normal evolution of [123I]IMP SPECT pattern as a(More)
The objective of the present study was to develop a cellular phenotype assay for nucleotide excision repair (NER), using benzo[a]pyrene diol epoxide (BPDE) as model mutagen. Since in vitro exposure to BPDE may lead to DNA strand breaks resulting from both direct interaction with DNA and incisions introduced by the repair enzymes, we aimed to discriminate(More)
In Western countries, the transport of triacylglycerols by plasma triacylglycerol-rich lipoproteins (chylomicra and very-low-density lipoproteins (VLDL)) accounts for approximately 100 g lipids/d and represents a major pathway in the delivery of energy to tissues. Fat emulsions have been developed to resemble endogenous chylomicra (Wretlind, 1981). However,(More)
AIM A new technique allowing placement of umbilical silicone venous catheters (USVC) is described and compared with percutaneous silicone venous catheters (PSVC). METHODS Data were retrospectively recorded for 198 infants with USVC and 141 infants with PSVC. RESULTS Overall rate of complications was low and comparable in both groups: thrombosis 1.2%,(More)
