OBJECTIVE To evaluate the functional results from reverse arthroplasty and its complications and relationships with types of injury. METHODS Twenty-seven shoulders (26 women and one man) were treated. The patients were assessed using the UCLA functional scale. The implant used was the Delta Xtend Depuy(®) model. The injuries were classified using the Seebauer method for the degree of arthropl...

BACKGROUND Retrieval studies have suggested that the cause of femoral implant failure after metal-on-metal hip resurfacing is multifactorial. Both varus positioning of the femoral component and notching of the superior part of the femoral neck have been associated with femoral component failure. The hypotheses of this study were that placement of a femoral resurfacing component alters femoral n...

a microprocessor system capable of averaging 256 QRS complexes to reduce noise. The QRS was digitally filtered and the root-mean-square (RMS) voltage of the residual (80-300 Hz) signal computed. High-frequency RMS values were significantly (p < 0.01) greater in leads II, III and aV7 in normal subjects (n = 12) than in patients with inferior infarction (n = 12). Similarly, high-frequency RMS val...

Cogging torque is the major limitation of axial flux permanent magnet motors. The reduction of cogging torque during the design process is highly desirable to enhance the overall performance of axial flux permanent magnet motors. This paper presents a double-layer magnet design technique for cogging torque reduction of axial flux permanent magnet motor. Initially, 250 W, 150 rpm axial flux brus...

Ventricular arrhythmias due to ARVD and right ventricular outflow tract arrhythmia (RVOTA) share the same left bundle branch block pattern with inferior axis on the ECG. The former has a more malignant course while the latter has a better prognosis and is more amenable to radiofrequency catheter ablation. Hence differentiating them is of utmost clinical importance in the management of these pat...

Wingless (Wg)/Wnt signaling is fundamental inmetazoan development. Armadillo (Arm)/β-catenin andDishevelled (Dsh) are key components of Wnt signal transduction. Recent studies suggest that intracellular trafficking of Wnt signaling components is important, but underlying mechanisms are not well known. Here, we show that Klp64D, the Drosophila homolog of Kif3A kinesin II subunit, is required for...

PURPOSE To report the clinical and radiographic results and complications of the Delta III reverse prosthesis. METHODS 24 women and 2 men aged 62 to 84 (mean, 75) years underwent total shoulder replacement using the Delta III reverse prosthesis. Patient diagnoses were massive rotator cuff tear (n=20), disabling sequelae of proximal humeral fractures (n=3), and failure of an unconstrained arth...

The shape of a premature ventricular complex (PVC) might reflect the presence or absence of myocardial disease. To test this, 100 patients with a PVC on a 12-lead electrocardiogram at cardiac catheterization or nuclear angiography were classified according to PVC morphology. Group 1 (n = 50) had PVC QRS complexes with either smooth and uninterrupted contour or with narrow (less than 40 msec) no...
