background: it is suggested that ha-1 mismatching among hematopoietic stem cell transplanted recipients-donors is associated with acute graft-versus-host disease (agvhd). so the aim of this study was to evaluate ha-1 frequency and examine the correlation between ha-1 disparity and gvhd patients who received transplantation from a hla-identical sibling. samples and methods: the dna was extracted...

Background: It is suggested that HA-1 mismatching among hematopoietic stem cell transplanted recipients-donors is associated with acute graft-versus-host disease (aGVHD). So the aim of this study was to evaluate HA-1 frequency and examine the correlation between HA-1 disparity and GVHD patients who received transplantation from a HLA-identical sibling. Samples and Methods: the DNA was extracted...

conclusions the x-intercepts (point at which the fdc crosses the x-axis) were on average more in the base-in direction, y-intercepts (point at which the fdc crosses the y-axis) were shifted in the exo direction, and slopes were steeper in the symptomatic group. results there were more subjects with exo fixation disparity than eso fixation disparity in the study sample. the means for fixation di...

In this paper, a new approach for optimizing disparity candidates space is proposed for the solution of dense stereo matching problem. The main objectives of this approachare the reduction of average number of disparity candidates per pixel with low computational cost and high assurance of retaining the correct answer. These can be realized due to the effective use of multiple radial windows, i...

When our two eyes view incompatible images, the brain invokes suppressive processes to inhibit one image, and favor the other. Two phenomena are typically observed: dichoptic masking (reduced sensitivity to one image) for brief presentations, and binocular rivalry (alternation between the two images), over longer exposures. However, it is not clear if these two phenomena arise from a common sup...

purpose: to compare the refractive results of penetrating keratoplasty (pk) in two groups of patients with keratoconus undergoing corneal grafting with different amounts of donor-recipient disparity (0.25 and 0.5 mm). methods: as a randomized clinical trial and after performing a complete ocular examination and vitreous length measurement, 30 patients with keratoconus were randomly assigned in ...

purpose: to report two patients with keratoconus who underwent regrafting to correct anisometropia and high astigmatism after penetrating keratoplasty. patients and findings: the first case is a 34-year-old man with keratoconus who had undergone penetrating keratoplasty. the sutures were removed 6 months postoperatively that led to high hyperopia. regraft was performed considering vitreous leng...

In his study of depth from monocular elements, Kaye (1978) [Kaye, M. (1978). Stereopsis without binocular correlation. Vision Research, 18(8), 1013-1022] reported that monocular stimuli, briefly presented to one eye in a stereoscopic display, generated reliable depth percepts. Here we replicate and extend Kaye's findings in an effort to identify the mechanism underlying the phenomenon. Our expe...

background hepatitis c virus (hcv) infection is the most significant source of chronic liver diseases in the globe. about 170 million individuals are infected by hcv worldwide. the reported prevalence of hcv in different areas of khyber pakhtunkhwa (kp) ranges from 4.1 to 36%. objectives the current study aimed to analyze the true prevalence of hcv infection in khyber pakhtunkhwa, pakistan. mat...
