Background: Evaluation of the accurate position after radial head arthroplasty remains a challenge for surgeons.Standard radiographs are used to evaluate the position of the implant, however, results regarding radiographicdeficiencies on clinical outcome are not consistent. In this retrospective study our main aim was to determine if subtleradiographic deficiencies after radia...

Radial tunnel syndrome is a disease which we should consider it in elbow and forearm pains. It is diagnosed with lateral elbow and dorsal forearm pain may radiate to the wrist and dorsum of the fingers. The disease is more prevalent in women with the age of 30 to 50 years old. It occurs by intermittent compression on the radial nerve from the radial head to the inferior border of the supinator ...

In many parts of the central nervous system, the elongated processes of radial glial cells are believed to guide immature neurons from the ventricular zone to their sites of differentiation. To study the clonal relationships of radial glia to other neural cell types, we used a recombinant retrovirus to label precursor cells in the chick optic tectum with a heritable marker, the E. coli lacZ gen...

The parabolic partial differential equation arises in many application of technologies. In this paper, we propose an approximate method for solution of the heat and advection-diffusion equations using Laguerre-Gaussians radial basis functions (LG-RBFs). The results of numerical experiments are compared with the other radial basis functions and the results of other schemes to confirm the validit...

We introduce the concepts of second-order radial composed tangent derivative, second-order radial tangent derivative, second-order lower radial composed tangent derivative, and second-order lower radial tangent derivative for set-valued maps by means of a radial tangent cone, second-order radial tangent set, lower radial tangent cone, and second-order lower radial tangent set, respectively. Som...

Background:  The purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   Methods:  This is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. The average time between implantation and removal was 23 month...

BACKGROUND Literature suggests that radial access is associated with higher radiation doses than femoral access. AIMS To compare patient radiation exposure during coronary angiography (CA) and percutaneous coronary intervention (PCI) with radial versus femoral access. METHODS RAY'ACT is a nationwide, multicentre, French survey evaluating patient radiation in interventional cardiology. Varia...

Polarized radial glia are crucial to the formation of the cerebral cortex. They serve as neural progenitors and as guides for neuronal placement in the developing cerebral cortex. The maintenance of polarized morphology is essential for radial glial functions, but the extent to which the polarized radial glial scaffold is static or dynamic during corticogenesis remains an open question. The dev...

The radial velocity technique was utilized to make the first exoplanet discoveries and continues to play a major role in the discovery and characterization of exoplanetary systems. In this chapter we describe how the technique works, and the current precision and limitations. We then review its major successes in the field of exoplanets. With more than 250 planet detections, it is the most prol...

Introduction Case Report Discussion References Abstract A case of 28-year-old man with closed fracture dislocation of the radial head following a fall from height is reported. He was treated with radial head excision. The radial head is an important stabilizer of the elbow, thus the rationale of radial head excision in management of radial head fractures should be scrutinized. There is much deb...
