children with attention-deficit/hyperactivity disorder (adhd) react explosively and inappropriately to emotional stimuli. it could be hypothesized that these children have some impairment in attending to emotional cues. based on this hypothesis, we conducted this study to evaluate visual directions of children with adhd towards paired emotional scenes.thirty boys between the ages of 6 and 11 ye...

PURPOSE Infantile esotropia is linked strongly to latent fixation nystagmus (LN) in human infants, but many features of this comorbidity are unknown. The purpose of this study was to determine how the duration of early-onset strabismus (or timeliness of repair) affects the prevalence of LN in a primate model. METHODS Optical strabismus was created in infant macaques by fitting them with prism...

OBJECTIVE To further assess oculomotor control of patients with Parkinson disease (PD) during fixation and with movement. DESIGN Case-control study. SETTING A Parkinson disease research, education, and clinical center. PATIENTS One hundred twelve patients with PD, including 18 de novo untreated patients, and 60 age-matched controls. INTERVENTION Modern, precise eye tracking technology was...

OBJECTIVE This study investigated the importance of iliac fixation to secure endograft fixation. MATERIALS AND METHODS Computed tomography (CT) scans of patients who underwent endovascular aneurysm repair with an endoprosthesis of great columnar strength (Talent stent graft) were analysed retrospectively. Patients were enrolled consecutively between June 2000 and January 2007 and prospectivel...

After growth on various carbon sources, sonic extracts of Hydrogenomonas facilis contained ribulosediphosphate (RuDP) carboxylase and phosphoribulokinase (Ru5-P kinase). After very short sonic treatment, a reductive adenosine triphosphate (ATP)-dependent incorporation of (14)CO(2) was also detectable. Reduced nicotinamide adenine dinucleotide (NADH(2)) served as reductant 30-fold more effective...

Processing in our visual system is functionally segregated, with the fovea specialized in processing fine detail (high spatial frequencies) for object identification, and the periphery in processing coarse information (low frequencies) for spatial orienting and saccade target selection. Here we investigate the consequences of this functional segregation for the control of fixation durations dur...

OBJECTIVES The aim of this study is to compare two methods of internal fixations of fractured medial malleolus which are simple screw fixation and tension band wiring. PATIENTS AND METHODS Over 5 years we grouped 20 patients with fractured medial malleolus into two groups of operative treatments, group1 treated by malleolar screw fixation and group2 by tension band wiring. The patients were w...

Many eye-tracking data analyses rely on the Area-of-Interest (AOI) methodology, which utilizes AOIs to analyze metrics such as fixations. However, AOI-based methods have some inherent limitations including variability and subjectivity in shape, size, location of AOIs. In this article, we propose an alternative approach traditional AOI dwell time analysis: Weighted Sum Durations (WSD). This decr...

Study Design: Randomized controlled trial. Place and Duration: The Department Othropedic surgery, Ghurki Trust Teaching Hospital Lahore, Pakistan from May 2021 to November 2021. Methodology: A total 7...
