Background: Celiac is one the most common causes of malabsorption and is an autoimmune disorder resulting in damage to intestinal epithelial cells by self T lymphocytes. The main culprit is gluten. The aim of our study was to assess the histopathologic findings of patients suspicious to have celiac disease in their first admission and compare them with serologic findings (endomyosial antibody t...

aim : the aim of this study was to discuss the prevalence of celiac disease (cd) in dyspeptic patients. background : although severe mucosal abnormality with villous atrophy (lesions marsh iii) is at present the gold standard for the diagnosis of cd, presentation with non-specific microenteropathy (marsh i-ii) with positive serology is also common. patients with dyspepsia, specific cd antibodie...

A detailed record of the Late Holocene sea level rise and landscape evolution that has taken place on the Georgia coast is contained within the sedimentary stratigraphy of its salt marsh depositional basins. Global relative sea level (RSL) has risen during the Late Holocene, and the rate of rise has accelerated during the Anthropocene. Jones Narrows marsh stratigraphy and radiocarbon analysis i...

We reconstruct past accretion rates of a salt marsh on the island of Sylt, Germany, using measurements of the radioisotopes Pb and Cs, as well as historical aerial photographs. Results from three cores indicate accretion rates varying between 1 and 16 mm year. Comparisons with tide gauge data show that high accretion rates during the 1980s and 1990s coincide with periods of increased storm acti...

Research at 10 locations in coastal subtropical Queensland, Australia, has shown that salt marshes contained heterogeneous distributions of eggshells of the pest and vector mosquito Aedes vigilax (Skuse) (Diptera:Culicidae). The eggshell distribution was related to specific vegetation assemblages, with a mix of the grass, Sporobolus virginicus (L.) Kunth (Poales: Poaceae), and the beaded glassw...

Salt marshes are valued for their ecosystem services, and their vulnerability is typically assessed through biotic and abiotic measurements at individual points on the landscape. However, lateral erosion can lead to rapid marsh loss as marshes build vertically. Marsh sediment budgets represent a spatially integrated measure of competing constructive and destructive forces: a sediment surplus ma...

Understanding themechanisms limiting and facilitating salt marsh vegetation initial establishment is of widespread importance due to the many valuable services salt marsh ecosystems offer. Salt marsh dynamics have been investigated by many previous studies, but the mechanisms that enable or disable salt marsh initial establishment are still understudied. Recently, the “windows of opportunity” (...

Molluscs, both gastropods and bivalves, appear to disproportionately influence the dynamics of salt marsh habitats. Bivalves typically are facilitators positively affecting the growth and survival of marshes, but gastropods may have unanticipated top-down effects through direct consumption of the predominant marsh vegetation, Spartina alterniflora. Natural, elevational differences in S. alterni...
