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...

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...

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...

results urban patients were more likely to receive supplementary information and being strongly encouraged by their nephrologists to seek transplant. all participants acknowledged “independence” as the main advantage of transplantation. increased freedom to travel and improved life expectancy were mentioned only among the urban groups. the main themes in all groups regarding perceived barriers ...

background : one of the major health policy issues, in the both developed and developing countries, is the equality in the distribution of health resources. the aim of this study was to investigate the disparity in the distribution of health physical resources across the provinces of iran in 2001 and 2011. methods : this was a cross-sectional retrospective study which investigated inequality in...

the reduction in regional differences to stop the movement and displacement of human forces and capital in the direction of preparing the ground for development is very effective. development means boosting human potentials for the improved utilization of his environment. rational utilization depends on economical, social and cultural particulars. therefore any kind of condition that is effecti...

purpose: to determine stereopsis with local (titmus) and global (tno) tests in symptomatic and asymptomatic subjects according to induced disparity (crossed or uncrossed). methods: in this cross sectional study, 80 students of zahedan university of medical sciences who fulfilled the inclusion criteria were randomly selected. at first, refractive error was determined by retinoscopy and then base...

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...
