The analysis of eye-tracking data hinges on the ability of automated algorithms to separate rapid saccadic eye movements from stable eye fixations. However, though it has long been known that changing the parameters of fixationidentification algorithms can lead to very different qualitative impressions, less is known about how algorithmic parameters interact with quantitative eye-tracking measu...

OBJECTIVE To compare the use of crossed K-wire and prebent intramedullary nail techniques for the fixation of distal radius metaphyseal fracture in children. METHODS Intraoperative and follow-up data for children with distal radius metaphyseal fracture, treated using crossed K-wire or prebent intramedullary nail fixation, were retrospectively analysed. Patient groups were matched for age, sex...

Results: (1) On the initial orienting indicators (direction of initial gaze and initial fixation latency) and the initial attention maintenance indicators (first fixation duration), the RD patients showed no attentional bias toward the emotional faces; (2) For the late-stage attention maintenance indicators (total fixation time), both the RD group and the HC group exhibited attentional bias tow...

The present study investigated the role of observer pain catastrophizing and personal pain experience as possible moderators of attention to varying levels of facial pain expression in others. Eye movements were recorded as a direct and continuous index of attention allocation in a sample of 35 undergraduate students while viewing slides presenting picture pairs consisting of a neutral face com...

Three stochastic eye-movement models for arithmetic and reading performance have been proposed, one for arithmetic and two for reading. Each model characterizes a real-time stochastic process in terms of fixation durations and saccadic movement, but only direction and length of saccades are considered, not acceleration or velocity. Aspects of the models that are emphasized, partly because of th...

background: flow cytometry (fcm) has been extensively used to study mammalian sperm in the areas of clinical andrology and reproductive toxicology. fcm provides a powerful advantage over microscopy technique in terms of rapid accurate and reproducible technology for the quantification of various cell characteristics including chromatin status. during spermiogenesis histones are replaced by prot...

PURPOSE To investigate the effects of an imaginary and a visual target on torsional optokinetic nystagmus (tOKN) and directional symmetry of tOKN. METHODS Torsional OKN was induced by a rotating random dot pattern (52 degrees in diameter, constant angular velocity: +/-30 deg/sec to +/-52 deg/sec) with an imaginary or a visual target in 11 eyes of 10 healthy humans by dual-search coil methods....

Background. We aimed to evaluate the effectiveness of a suture-fixation mucopexy procedure by comparing with Doppler-guided hemorrhoidal artery ligation (DGHAL) in the management of patients with grade III hemorrhoids. Methods. This was a randomized controlled trial. One hundred patients with grade III hemorrhoids were randomly assigned to receive suture-fixation mucopexy (n = 50) or DGHAL (n =...

background gabapentin is an anticonvulsant that has postoperative analgesic effects but there are limited studies on its postoperative administration. objectives the present study was conducted to evaluate the effect of the postoperative oral gabapentin on pain and morphine consumption. patients and methods in a double blind, randomized study, 64 patients undergoing internal fixation of tibia u...

patients and methods sixty elderly patients with intertrochanteric fractures were randomized for treatment with either skeletal traction (group a) or an external fixation (group b). in this study patients at least 60 years of age, with ao/ota a1 or a2 type fracture and intertrochanteric fracture as a result of minor trauma, were enrolled. results acceptable reduction was achieved in eight and 2...
