Participants' eye movements were monitored in an experiment that manipulated the frequency of target words (high vs. low) as well as their availability for parafoveal processing during fixations on the pre-target word (valid vs. invalid preview). The influence of the word-frequency by preview validity manipulation on the distributions of first fixation duration was examined by using ex-Gaussian...

Contemporary management of Grade IIIB open tibial fractures has evolved to include intravenous antibiotics, thorough interval surgical debridement, rigid skeletal fixation, early local or free tissue myoplasty, and liberal use of autogenous bone graft beneath a clean, stable wound. External fixation has been the skeletal stabilization of choice with the lowest reported deep sepsis rates. Pin tr...

INTRODUCTION: Initial implant stability is crucial to cementless knee replacement success, however the optimal design remains elusive. Previous biomechanical studies have aimed at quantifying initial stability using simplified loading scenarios. The objective of this study was to use a physiological relevant methodology which incorporates torsion, shear and compression forces to evaluate tibial...

Abstract We can focus visuospatial attention by covertly attending to relevant locations, moving our eyes, or both simultaneously. How does shifting versus holding covert during fixation compare with maintaining across saccades? acquired human fMRI data a combined saccade and task. On Eyes-fixed trials, participants either held at the same initial location (“hold attention”) shifted another mid...

Although porous-surfaced orthopedic implants have been designed for fixation by bone ingrowth, there is clinical evidence that this does not always occur. Initial implant movement relative to host bone can result in attachment by a non-mineralized fibrous connective tissue layer. The ranges of movement that result in either bone or fibrous connective tissue fixation are observed in dogs in two ...

Lumbosacral dislocations are rare disorders; since they were first reported by Watson-Jones [1], only 100 cases have appeared in the literature [2]. A traumatic bilateral lumbosacral dislocation is even rarer, with a mere 10 cases reported [3]. Because of its low incidence and atypical location, the lesion may often go unnoticed on initial clinical assessment [4]. Surgical treatment modalities ...

In this paper an alternative preparation and imaging method is presented that allows investigation of the fine structure of hepatic tissue within one hour after the initial fixation step. This approach involves, besides traditional fixation with glutaraldehyde, chemical drying and subsequent investigation of the samples with the new generation of user-friendly desktop scanning electron microsco...

Intertrochanteric fractures can be fixed with various implants surface or intramedullary implants. A study was done on Fixation of trochanteric Hip Nail/Intra Medullary Screw an innovative cephalomedullary nail designed by author to determine its efficacy, union operative use and functional outcome. Trochanteric hip were classified upon number parts, stable unstable in initial 43 cases. All as ...

We show that the initial ocular following responses elicited by motion of a large pattern are modestly attenuated when that pattern is shifted out of the plane of fixation by altering its binocular disparity. If the motion is applied to only restricted regions of the pattern, however, then altering the disparity of those regions severely attenuates their ability to generate ocular following. Th...
