A study has been made in a series of 45 patients, 36 of whom were re-examined and 11 of whom replied to a questionnaire, of the fate of knees that had suffered a rupture of the posterior cruciate ligament which had not had a primary or secondary repair. The follow-up was between 5 and 44 years, with a mean of 15 years. In the 36 who were reviewed, 21 showed(More)
Seven fasting subjects were fitted with nasogastric and nasoduodenal tubes and received intragastrically a coarsely emulsified test meal. Gastric and duodenal aspirates were collected after 1, 2, 3, and 4 h. In the duodenum, most lipids (> 90%) were present as emulsified droplets 1-100 microns in size. Large droplets and unemulsified material present in the(More)
BACKGROUND The extent of fat emulsification affects the activity of digestive lipases in vitro and may govern digestion and absorption of dietary fat. OBJECTIVE We investigated the effect of the fat globule size of 2 enteral emulsions on fat digestion and assimilation in humans. DESIGN Healthy subjects received intragastrically a coarse (10 microm) and(More)
Fasting subjects were intragastrically intubated and received a coarsely emulsified test meal. Gastric aspirates were collected after 1, 2, 3, and 4 h. During digestion in the stomach, unemulsified lipids (> or = 100 microns) represented a minor fraction. A significant amount of the large 70- to 100-microns lipid droplets disappeared, and fine 1- to(More)
We aimed to provide basic data on the processing of vitamin A and E in the human gastrointestinal tract and to assess whether the size of emulsion fat globules affects the bioavailability of these vitamins. Eight healthy men received intragastrically two lipid formulas differing in their fat-globule median diameter (0.7 vs. 10. 1 microm. Formulas provided(More)
We present a new direct Poisson disk sampling for surface meshes. Our objective is to sample triangular meshes, while satisfying good blue noise properties, but also preserving features. Our method combines a feature detection technique based on vertex curvature, and geodesic-based dart throwing. Our method is fast, automatic, and experimental results prove(More)
BACKGROUND The existence of endosonographic abnormalities of the oesophagus in achalasia is discussed. The place of endoscopic ultrasonography (EUS) needs to be clarified. PATIENTS Thirty five untreated patients suffering from achalasia and 28 controls without oesophageal disease were prospectively enrolled since 1993. Pseudoachalasia was diagnosed in two(More)
We propose in this paper a novel sampling method and an improvement of a spectral analysis tool that both handle complex shapes and sharp features. Starting from an arbitrary triangular mesh, our algorithm generates a new sampling pattern that exhibits blue noise properties. The fidelity to the original surface being essential, our algorithm preserves sharp(More)
Our objective is to include in stereoscopic 3D acquisition systems new technologies to automatically detect deformations on aircraft fuselages. We propose in this paper a semiregular mesh reconstruction dedicated to stereoscopic scanners, combined to a multiresolution analysis tool that detects dents on smooth surfaces. The proposed technique for(More)
