Contrast echocardiography can predict pathologic area at risk during acute coronary occlusion. In this study we evaluated (1) whether the intensity and timing of contrast appearance in ischemic regions can provide a quantitative measure of residual myocardial perfusion, and (2) whether changes in these parameters observed after serial injections reflect changes in blood flow to acutely ischemic...

PURPOSE To review the functional outcome and local recurrence rate of 29 patients who underwent segmental excision or intralesional curettage with adjuvant therapy for giant cell tumour (GCT) of bone. METHODS Records of 17 men and 12 women (mean age, 30.17 years) who underwent segmental excision (n=18) or intralesional curettage followed by adjuvant therapy (n=11) for GCT of the femur (n=13),...

The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...

(3) The Spoken Language Group at MIT's Laboratory for Computer Science also reported results for both the RM and ATIS SPREC test material [3]. The MIT SUMMIT system is a "segment-based" speech recognition system, including a front end that incorporates a model of the auditory system, a hierarchical segmentation algorithm to identify a network of possible acoustical segments, segmental measureme...

A morbidly obese woman presented with exertional dyspnoea and leg swelling. Past medical history included deep venous thrombosis and atrial fibrillation. Arterial blood gases demonstrated chronic respiratory acidosis and type 2 respiratory failure. Further evaluation consisted of spirometry (restrictive defect), Epworth scoring, overnight pulse oximetry (median oxygen saturation 68%) and echoca...

BACKGROUND Comminuted fractures can occur due to severe traumas. The treatment of these fractures that may cause serious morbidity and sometimes mortality is N-butyl cyanoacrylate. It has been reported that this adhesive provides sufficient rigid fixation for bone healing. This study aims to examine cyanoacrylate radiologically and histologically to determine whether it provides adequate recove...

We have investigated a novel method of spectral estimation based on mixture of Gaussians in a sinusoidal analysis and synthesis framework. After quantisation of this parametric scheme a xed frame-rate coder operating at a bit-rate of around 2.4 kbits/s has been developed. This paper describes an extension to this spectral model based on constraining the parameters of the mixture of Gaussians to...
