BACKGROUND Coronal tibiofemoral (CTF) subluxation is a common finding in knee osteoarthritis (OA) which can be related to poor pain scores and tibial spine impingement. In this study we describe a new method for measuring CTF subluxation and present validation of the method using cadaveric knees. METHODS A prototype software code based on the ICP mathematical algorithm was developed to measur...

BACKGROUND Gaining and maintaining spinal balance after surgery is of great importance for early onset scoliosis (EOS). However, tendency of balance on the coronal plane after growing rod surgery has not been studied before. This study evaluated the effect of growing rod treatment on coronal balance (CB) during serial lengthening surgeries in EOS. METHODS All EOS patients treated with growing...

The model of Parker (1972) is one of the mostly discussed mechanisms for coronal heating and has generated much debate. We have recently obtained new scaling results in a two-dimensional (2D) version of this problem suggesting that the heating rate becomes independent of resistivity in a statistical steady state (Ng & Bhattacharjee 2008) Our numerical work has now been extended to 3D by means o...

Fig. 1.-Case 1. Skull films. A, Frontal projection. Left orbit is small and round , with normally oriented orbital roof and lesser wing of sphenoid . Lateral wall of left orbit is broad and decreased in height; frontozygomatic suture is obliterated. B, Submentovertical projection. Left frontal area is depressed. Lateral wall of left orbit is short and directed more lateral than normal. There is...

Context. Coronal holes (CHs) are deemed to be the sources of the fast solar wind streams that lead to recurrent geomagnetic storms and have been intensively investigated, but not all the properties of them are known well. Aims. We mainly research the response of the solar atmosphere to the magnetic field evolution in a CH region, such as magnetic flux emergence and cancellation for both network...

This paper argues for a distinct treatment of expressive palatalization – an apparently phonologically unmotivated process that applies in babytalk registers, diminutive constructions, and sound symbolism. As evidence we present results of a cross-linguistic survey of expressive palatalization and of two experiments testing native speakers’ intuitions about alternations in Japanese mimetic voca...

We have a new view of the time behavior of the inner solar corona via the extensive soft X-ray observations of Yohkoh. These show many forms of expansion of coronal material, ranging from highly collimated structures (jets) to large-scale evacuations ("dimmings") of the diffuse corona. We review these effects, emphasizing those probably related to CMEs, and present a preliminary classification ...

AIM The focus of this study was to examine the staining potential of calcium hydroxide (Ca(OH)2) on tooth structure following the removal of AH26 root canal sealer. METHODS AND MATERIALS Fifty maxillary anterior teeth were prepared and obturated with AH26 and gutta percha. The sealers were then removed 24 hours later and the teeth were randomly divided into two groups. Ca(OH)2 was then placed...

BACKGROUND Radiography, typically the first-line imaging study for diagnosis of craniosynostosis, exposes infants to ionizing radiation. We aimed to compare the accuracy of cranial ultrasound (CUS) with radiography for the diagnosis or exclusion of craniosynostosis. METHODS Children aged 0 to 12 months who were assessed for craniosynostosis during 2011-2013 by using 4-view skull radiography a...
