Severe breathing problems arise in multiple rib fractures. As a result, many advantages of the surgical stabilization of the chest wall have been reported. Especially, shortening mechanical ventilation, along with a decrease in the duration of intensive care unit stay, is important for the prevention of possible infection complications. In this study, the dramatic improvement of the breathing p...

The present study investigated whether Short Message Service shortcuts are more difficult to process in sentence context than the spelled-out word equivalent and, if so, how any additional processing difficulty arises. Twenty-four student participants read 37 Short Message Service shortcuts and word equivalents embedded in semantically plausible and implausible contexts (e.g., He left/drank u/y...

The purpose of the present study was to examine the influence of task set on the spatial and temporal characteristics of eye movements during scene perception. In previous work, when strong control was exerted over the viewing task via specification of a target object (as in visual search), task set biased spatial, rather than temporal, parameters of eye movements. Here, we find that more parti...

A simulated scotoma was stabilized on the fovea of 23 normal human subjects while they searched for acuity targets in arrays of non-targets. Search time doubled with a 20 min arc scotoma, and eye fixation duration increased by about 15% when compared to no-scotoma control conditions. Search difficulty was graded by adjusting acuity target size, search element density and contrast. Search time a...

Eye movements were tracked of students, with and without touch-typing skills, while they translated three short texts of different levels of complexity under three different time constraints. The aim was to chart the distribution of visual attention between source and target texts, and to study how visual attention was affected by text complexity and time pressure. Participants with touch-typin...

The new Aveir VR (Abbott Medical, CA) active-fixation leadless pacemaker (LP) offers several novel innovations. It uses a unique mapping capability to help reduce repositioning attempts prior fixation and utilizes helical mechanism for implantation chronic retrieval. We describe the current largest real world descriptive single center experience with LP. This retrospective study describes chara...

This study investigated the relationship between reading speed and oculo-motor parameters when normally sighted observers had to read single sentences with an artificial macular scotoma. Using multiple regression analysis, our main result shows that two significant predictors, number of saccades per sentence followed by average fixation duration, account for 94% of reading speed variance: readi...

Expanding on the seminal work of G. Buswell (1935) and I. A. Yarbus (1967), we investigated how task instruction influences specific parameters of eye movement control. In the present study, 20 participants viewed color photographs of natural scenes under two instruction sets: visual search and memorization. Results showed that task influenced a number of eye movement measures including the num...

Purpose: Tension band wiring technique has been widely used for treating patellar fracture. Conventional techniques are associated with some complications and several modifications have introduced to increase stabilization. The purpose of this study was compare two different fixation techniques, the one-end both-ends Kirschner wire bending methods. Methods: We retrospectively reviewed patient d...

This study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. One hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. Maximum load to failure, average structural rigidity, and energ...
