BACKGROUND Celiac disease has been reported to be associated with gastric abnormalities. The aim of this study was to assess the relationship between the prevalence of celiac disease and Helicobacter pylori infection in an Iranian population of 250 patients. METHODS Biopsies were taken from the gastric antrum and duodenum. Morphology and histology were evaluated using the updated Sydney syste...

fuzzy segmentation is an effective way of segmenting out objects in images containing both random noise and varying illumination. in this paper, a modified method based on the comprehensive learning particle swarm optimization (clpso) is proposed for pixel classification in hsi color space by selecting a fuzzy classification system with minimum number of fuzzy rules and minimum number of incorr...

Wetlands provide many benefits, such as water storage, flood control, transformation and retention of chemicals, habitat for species plants animals. The ongoing degradation wetlands in the Great Lakes basin has been caused by a number factors, including climate change, urbanization, agriculture. Mapping monitoring across large spatial temporal scales have proved challenging; however, recent adv...

aim : to assess the clinical characteristic of cd as well as correlation of symptoms and the degrees of intestinal mucosal lesions in iranian children. background : microscopic enteritis (marsh 0-ii) is associated with malabsorption. patients and methods : from august 2005 to september 2009, 111 cases with malabsorption and classical gastrointestinal symptoms were evaluated. results : the mean ...

Rapid human development in coastal areas is introducing significant amounts of novel habitat and leading to widespread simplification. To predict how species will respond these changes, it important understand organisms interact with habitats versus naturally existing habitats. In this study, we used traditional fish sampling gear (fyke nets minnow traps) a Dual-Frequency Identification Sonar (...

Many sea level rise adaptation plans emphasize the protection of adjacent uplands to allow for inland salt marsh migration, but little empirical information exists on this process. Using aerial photos from 1930 and 2006 of Delaware Estuary coastal habitats in New Jersey, I documented the rate of coastal forest retreat and the rate of inland salt marsh migration across 101.1 km of undeveloped sa...

Tidal marshes maintain elevation relative to sea level through accumulation of mineral and organic matter, yet this dynamic accumulation feedback mechanism has not been modeled widely in the context of accelerated sea-level rise. Uncertainties exist about tidal marsh resiliency to accelerated sea-level rise, reduced sediment supply, reduced plant productivity under increased inundation, and lim...

BACKGROUNDS Iron deficiency anemia (IDA) is one of the well recognized presentations of celiac disease (CD). According to the lack of data from our population in this regard, we determined the prevalence of CD in patients presenting with IDA to see if it is worthwhile to do a precise screening for CD in such patients. METHODS This cross-sectional study was conducted on patients referred with ...
