BACKGROUND & AIMS Aminosalicylates are widely used in the treatment of ulcerative colitis (UC). Balsalazide is a novel mesalamine prodrug, activated by colonic bacteria. The aim of this study was to compare the efficacy and safety of balsalazide with that of a pH-dependent formulation of mesalamine in active UC. METHODS A randomized, double-blind study… (More)
Morgan and colleagues demonstrated that the RPE cell mosaic can be resolved in the living human eye non-invasively by imaging the short-wavelength autofluorescence using an adaptive optics (AO) ophthalmoscope. This method, based on the assumption that all subjects have the same longitudinal chromatic aberration (LCA) correction, has proved difficult to use… (More)
Hemaspaandra and Torenvliet showed that each P-selective set can be accepted by a polynomial-time nondeterministic machine using linear advice and quasi-linear nondeterminism. We show that each P-selective set can be accepted by a polynomial time nondeterministic machine using linear advice and linear nondeterminism.
OBJECTIVE To assess the response of healthy infants to airway hypoxia (15% oxygen in nitrogen). DESIGN Interventional study. SETTINGS Infants' homes and paediatric ward. SUBJECTS 34 healthy infants (20 boys) born at term; mean age at study 3.1 months. 13 of the infants had siblings whose deaths had been ascribed to the sudden infant death syndrome. … (More)
Hemaspaandra and Torenvliet showed that each P-selective set can be accepted by a polynomial-time nondeterministic machine using linear advice and quasilinear nondeterminism. We extend this by showing that each P-selective set can be accepted by a polynomial-time nondeterministic machine using linear advice and linear nondeterminism.
A distortion mapping and computational image unwarping method based on a network interpolation that uses radial basis functions is presented. The method is applied to correct distortion in an off-axis head-worn display (HWD) presenting up to 23% highly asymmetric distortion over a 27°x21° field of view. A 10(-5) mm absolute error of the mapping function… (More)
OBJECTIVES Although the geometry of the trochlear groove is considered important in the pathogenesis of patellofemoral joint pathology it is unclear how the shape of the trochlear groove relates to patella morphology. This cross-sectional study investigated the relationship between the shape of the trochlear groove and patella cartilage and bone morphology… (More)
