Atomic force microscopy has been used to follow in real time the adsorption from solution of two of the gliadin group of wheat seed storage proteins onto hydrophilic (mica) and hydrophobic (graphite) surfaces. The liquid cell of the microscope was used initially to acquire images of the substrate under a small quantity of pure solvent (1% acetic acid). Continuous imaging as an injection of glia...

Gliadin was reacted with citric acid under weak acidic and weak alkaline conditions in both wet and dry states and the reaction mechanism was studied. The low morphological stability in an aqueous environment and inferior mechanical properties have restricted the applications of plant proteins, although these materials possess a unique structure, biocompatibility and biodegradability. Carboxyli...

Celiac disease is characterized by intestinal inflammation triggered by gliadin, a component of dietary gluten. Oral administration of proteases that can rapidly degrade gliadin in the gastric compartment has been proposed as a treatment for celiac disease; however, no protease has been shown to specifically reduce the immunogenic gliadin content, in gastric conditions, to below the threshold s...

The new branched spike forms of wheat were synthesized from the crosses between a complex wheat line 171ACS {Aegilotriticale [(T. durum Desf. × Ae. tauschii Coss.) × Secale cereale L. ssp. segetale Zhuk.] × T. aestivum L. ‘Chinese Spring’} (2n = 6x = 42, AABBDD) and durum wheat variety T. durum Desf. ‘Bereketli-95’ (2n = 4x = 28, AABB) and also between a dwarf line 237KACS (Aegilotriticale × T....

Endomysial antibodies are a hallmark of coeliac disease. The existence of autoantibodies whose titres fluctuate with ingestion of gliadin is enigmatic.Gliadin seems to drive this antibody secretion as endomysial antibodies are produced in biopsy samples cultured with a peptic/tryptic digest of gliadin. The phenomenon of endomysial antibodies has been explained by molecular mimicry between gliad...

The level of IgA antibodies to gluten and gliadin proteins found in grains and to casein found in milk, as well as the level of IgG to gluten and gliadin, have been examined in 23 girls with Rett syndrome and 53 controls. Highly statistically significant increases were found for the Rett population compared to the controls. The reason for this remains unknown, but because IgA antibodies reflect...

BACKGROUND Future European Community regulations will require a sensitive and specific assay for measurement of coeliac toxic gluten proteins in foods marketed as gluten-free. To avoid spurious cross reactions with non-toxic proteins, specific antibodies and target antigens are required. A synthetic 19 amino acid peptide of A gliadin has been shown to cause deterioration in the morphology of sm...

celiac disease (cd) is now considered a multiple and systemic immune-mediate disorder triggered by the ingestion of wheat gluten and related proteins. following the discovery of a link between gluten and cd, it was demonstrated that gliadin, one of the two principal protein groups comprising gluten, plays a key role in cd. it has since become clear that the different and crucial roles of gliadi...

A new method of sequential extraction of proteins followed by quantitative and qualitative determination by reverse-phased high-performance liquid chromatography (RP-HPLC) was used to analyse the effect of environmental conditions (3N fertilisation rates, two varieties, two sites and two growing seasons) on quantitative and qualitative variation of wheat storage proteins. The results showed tha...
