BACKGROUND Several studies have described the differences in electromyographic activity and histological changes of paravertebral muscles in patients with adolescent idiopathic scoliosis (AIS). However, there is little knowledge about the muscle volumetric and fatty infiltration imbalance of patients with AIS. MATERIAL AND METHODS Thirty-four patients with AIS were evaluated with standardized a...

In this paper, we proved the following result: Let G be a (k + 2)-connected, non-(k − 3)apex graph where k ≥ 2. If G contains three k-cliques, say L1, L2, L3, such that |Li ∩ Lj| ≤ k − 2(1 ≤ i < j ≤ 3), then G contains a Kk+2 as a minor. Note that a graph G is t-apex if G− X is planar for some subset X ⊆ V (G) of order at most t . This theorem generalizes some earlier results by Robertson, Seym...

AIM To compare ex vivo the performance of the Apex Finder and the Root ZX apex locators, with and without irrigant, in canals having different diameters. METHODOLOGY Sixty canals in 60 teeth were prepared using stainless steel hand files and 0.04 taper NiTi rotary instruments. During preparation the narrowest diameter of the canal was transported to the apical root surface. The canals were ir...

AIMS Pulsed Doppler measurement of left atrial appendage (LAA) emptying velocity, a marker of left atrium contractile function, has been shown to predict success of cardioversion, thrombo-embolic risk, and maintenance of sinus rhythm after cardioversion and pulmonary vein isolation. However, in the published literature, emptying velocity measurement location is not uniform, and no standard curr...

one of the fundamental parameters for endodontic success. Traditionally this has been determined using radiography, but electronic apex locators are increasingly being used. Electronic apex locators reduce the number of radiographs required and assist where radiographic methods create difficulty. The use of an electronic apex locator in combination with the radiograph is greater precision in th...

APEX: the APL Parallel Executor Robert Bernecky Master of Science Graduate Department of Computer Science University of Toronto 1997 APEX is an APL-to-SISAL compiler, generating high-performance, portable, parallel code that executes up to several hundred times faster than interpreted APL, with serial performance of kernels competitive with FORTRAN. Preliminary results indicate that acceptable ...

We present the case of an immunocompetent man who presented with multiple and progressive cranial nerve palsies. The cause was found to be aspergillosis of the petrous bone, arising as a result of chronic fungal otitis media. Despite treatment with local excision and systemic anti-fungal therapy, he died after suffering a subarachnoid haemorrhage. Diagnosis rests upon prompt radiological imagin...
