purpose many factors such as lumbar instability and spinopelvic alignment are associated with low back pain. our purpose was to analyze the pelvic incidence - one of spinopelvic alignment parameters- and spine instability correlations in patients with chronic low back pain. methods fifty-two patients suffering from chronic low back pain entered this case control study. lateral spine radiography...

stem cell therapy has been applied for the treatment of degenerative diseases encompassing corneal disorders.this consideration is regarding the unique characteristics of stem cells including self-renewal and pluripotency. some corneal diseases result from deficiencies in the limbal region. in these conditions, limbal stem cell therapy is considered in which limbal stem cells are cultured in vi...

dioctophyma renale infection is found in a wide range of mammalian species, typically in temperate areas of the world. here, we report for the first time, the parasitism of a domestic dog by d. renale in hamedan, iran, a mountainous cold region, lacking significant amounts of rainfall, high humidity and temperature. a 2.5 yr old male mixed breed dog was presented with a two months history of pr...

conclusions results indicates that antigenic region of recombinant caga protein were recognized as an antigen , so it might be a candidate for the development of h. pylori vaccine, elisa kit designs and serological diagnosis of h. pylori infections. background helicobacter pylori is a human pathogen that causes chronic gastritis, which playsrole in gastric and duodenal ulcers, is also involved ...

background: y chromosomal microdeletion is an important genetic disorder, which may arise due to intrachromosomal recombination between homologous sequences in the male specific region of the human y chromosome. it is frequently associated with the quantitative reduction of sperm. the screening for y chromosomal microdeletions has a great clinical value. objective: to develop a sequence tagged ...

We present a novel methodology that utilizes four-dimensional (4D) space deformation to simulate a magnification lens on versatile volume datasets and textured solid models. Compared with other magnification methods (e.g. geometric optics, mesh editing), 4D differential geometry theory and its practices are much more flexible and powerful for preserving shape features (i.e. minimizing angle dis...

Identifying loss mechanisms and predicting device performance are key goals of device and process characterization. Photoconductance measurements allow the extraction of the Implied Voc and Suns Voc, which together can be used for process monitoring, for loss analysis and to identify the potential device performance in the absence of unwanted defects. In this paper, we measure the Implied Voc a...
