Celiac disease (CD) and gluten-related disorders are significant health and social issues in Western countries, and CD individuals need to exclude gluten from their diets. The adverse health impacts of CD have extended to Asian countries in which CD was not a problem previously. Thai commercial food products that do not contain wheat, rye, barley, or gluten on their labels were surveyed as to whether they were suitable for CD individuals by examining the absence of gluten or the presence of gluten <20 ppm...

Theterm gluten intolerance may refer to three types of human disorders: autoimmune celiac disease (CD), allergy to wheat and non-celiac gluten sensitivity (NCGS). Gluten is a mixture of prolamin proteins present mostly in wheat, but also in barley, rye and oat. Gluten can be subdivided into three major groups: S-rich, S-poor and high molecular weight proteins. Prolamins within the groups possess similar structures and properties. All gluten proteins are evolutionarily connected and share the same ancestral origin...

PURPOSE OF REVIEW: A new syndrome responding to gluten-free diet and defined non-celiac gluten sensitivity entered the spectrum of gluten-related disorders, together with celiac disease and wheat allergy. However, its definition, prevalence, diagnosis, pathogenesis, treatment, and follow up are still controversial. The purpose of the review is to summarize the evidence and problems emerging from the current literature. RECENT FINDINGS: Direct implication of gluten in the onset of symptoms is often unproved as a low fermentable oligo-, di- and mono-saccharides and polyols diet or other components of cereals as wheat amylase trypsin inhibitor could be similarly involved...

Six soluble dietary fiber (SDF) fractions were prepared via stepwise ethanol precipitation from natural and fermented wheat bran. The chemical composition, molecular weight distribution, glycosidic linkage and substitution pattern of the SDF fractions were elucidated by sugar analysis, periodate oxidation and Smith degradation, molecular determination, and 1H nuclear magnetic resonance (NMR) analysis. The impacts of SDF fractions on the rheological properties and morphologies of doughs were investigated by farinography, rheometry and scanning electron microscopy (SEM) to clarify the relationship between the microstructural features of SDF fractions and the macroscopic properties of SDF-containing doughs...

There has been increasing interest in the entity "Non-celiac gluten sensitivity" in recent years which was first of its in 1980s. This "re-discovered" disorder is characterized by intestinal and extra-intestinal symptoms which occur after ingestion of gluten containing food. The number of such patients who neither have celiac disease nor wheat allergy, but appear to benefit from gluten withdrawal is increasing substantially. However it still remains a controversial and its pathogenesis is not well understood...

PURPOSE: Irritable bowel syndrome (IBS) is common but therapies are unsatisfactory. Food is often suspected as cause by patients, but diagnostic procedures, apart from allergy testing, are limited. Based on the hypothesis of non-celiac wheat sensitivity (WS) in a subgroup of IBS patients, we tested the long-term response to a gluten-free diet (GFD) and investigated HLA-DQ2 or -DQ8 expression as a diagnostic marker for WS in diarrhea-dominant (IBS-D) and mixed-type IBS (IBS-M). METHODS: The response to a GFD served as reference test for WS and HLA-DQ2/8 expression was determined as index test...

Prolyl oligopeptidase (POP, EC is a cytosolic serine protease that hydrolyses proline containing small peptides. The members of prolyl oligopeptidase family play important roles in many physiological processes such as neurodegenerative diseases, maturation and degradation of peptide hormones. Thus the enzyme has been purified and characterized from various sources to elucidate the potential use as therapeutics. In this study recombinant Myxococcus xanthus prolyl oligopeptidase expressed in E. coli was purified 60...

Sequential protein behavior in the wheat dough matrix under continuous mixing and heating treatment has been studied using Mixolab-dough samples from two Australian wheat cultivars, Westonia and Wyalkatchem. Size exclusion high performance liquid chromatography (SE-HPLC) and two-dimensional gel electrophoresis (2-DGE) analysis indicated that 32min (80°C) was a critical time point in forming large protein complexes and loosing extractability of several protein groups like y-type high molecular weight glutenin subunits (HMW-GSs), gamma-gliadins, beta-amylases, serpins, and metabolic proteins with higher mass...

Coeliac disease (CD) is an inflammatory disorder of the small intestine. It includes aberrant adaptive immunity with presentation of CD toxic gluten peptides by HLA-DQ2 or DQ8 molecules to gluten-sensitive T cells. A ω-gliadin/C-hordein peptide (QPFPQPEQPFPW) and a rye-derived secalin peptide (QPFPQPQQPIPQ) were proposed to be toxic in CD, as they yielded positive responses when assessed with peripheral blood T-cell clones derived from individuals with CD. We sought to assess the immunogenicity of the candidate peptides using gluten-sensitive T-cell lines obtained from CD small intestinal biopsies...

Background. Celiac disease seems to be rare in Colombians, but there are currently no data about the prevalence rates of symptomatic adverse reactions to gluten or adherence to gluten-free diet (GFD) in this population. Aim. to evaluate the self-reported prevalence rates of adverse reactions to gluten, adherence to GFD, and gluten-related disorders at population level in Colombia. Methods. A self-administered questionnaire-based cross-sectional study was conducted in a population from Northwest Colombia. Results...

The association between gluten related disorders and psychiatric diseases has been firmly demonstrated. Non celiac gluten sensitivity (NCGS) is a syndrome diagnosed in patients responsive to gluten free diet after ruling out celiac disease and wheat allergy. The pathogenesis of neuro-psychiatric disorders in NCGS is unclear. An association between gluten and schizophrenia was described for the first time in 1950 by Bender et al. In the 50', Dicke noted that gluten free diet improved mood in celiac patients...

Purified wheat starch (WSt) is commonly used in gluten-free products for celiac disease (CD) patients. It is mostly well-tolerated, but doubts about its safety for CD patients persist. One reason may be that most ELISA kits primarily recognize the alcohol-soluble gliadin fraction of gluten, but insufficiently target the alcohol-insoluble glutenin fraction. To address this problem, a new sensitive method based on the sequential extraction of gliadins, glutenins, and gluten from WSt followed by gel-permeation high-performance liquid chromatography with fluorescence detection (GP-HPLC-FLD) was developed...

Celiac disease (CD) is the world's most common genetic food intolerance disorder. Children with celiac disease cannot tolerate gluten, a storage protein in wheat, rye, and barley. The first recognizable symptom in children is often an oral manifestation, rather than the typical gastrointestinal symptoms. The purpose of this paper is to review the oral and dental manifestations of CD to help pediatric dentists identify and refer atypically symptomatic patients to their pediatricians.

Proanthocyanidins (PA) cross-link proteins and could expand wheat gluten functionality; however, how the PA MW or gluten profile affect these interactions is unknown. Effect of PA MW profile (sorghum versus grape seed PA) on dough rheology of high versus low insoluble polymeric protein (IPP) wheat flour was evaluated using mixograph, large (TA.XT2i) and small (HAAKE Rheostress 6000) deformation rheometry. Sorghum PA (93% polymeric) more effectively (p < 0.05) strengthened both glutens than grape seed PA (45% polymeric), without reducing gluten extensibility...

Wheat pasta has a compact structure built by a gluten network entrapping starch granules resulting in a low glycemic index, but is nevertheless unsuitable for gluten-intolerant people. High protein gluten-free legume flours, rich in fibers, resistant starch and minerals are thus a good alternative for gluten-free pasta production. In this study, gluten-free pasta was produced exclusively from faba, lentil or black-gram flours. The relationship between their structure, their cooking and Rheological properties and their in-vitro starch digestion was analyzed and compared to cereal gluten-free commercial pasta...

Oats are easily contaminated with gluten-rich kernels of wheat, rye and barley. These contaminants are like gluten 'pills', shown here to skew gluten analysis results. Using R-Biopharm R5 ELISA, we quantified gluten in gluten-free oatmeal servings from an in-market survey. For samples with a 5-20ppm reading on a first test, replicate analyses provided results ranging <5ppm to >160ppm. This suggests sample grinding may inadequately disperse gluten to allow a single accurate gluten assessment. To ascertain this, and characterize the distribution of 0...

INTRODUCTION: Celiac disease (CD) is caused due to intake of gluten, a protein component in wheat, barley, and rye. The only treatment currently available for CD is strict lifetime adherence to a gluten-free diet (GFD) which is a diet that excludes wheat, barley, and rye. There is limited information on barriers to following a GFD. The present study aimed to investigate the compliance with a GFD, barriers to compliance, and the impact of compliance on the quality of life (QOL) in Iranian children and adolescents suffering from CD...

Protein-based films and coatings are an interesting alternative to traditional petroleum-based materials. However, their mechanical and barrier properties need to be enhanced in order to match those of the latter. Physical, chemical, and biochemical methods can be used for this purpose. The aim of this article is to provide an overview of the effects of various treatments on whey, soy, and wheat gluten protein-based films and coatings. These three protein sources have been chosen since they are among the most abundantly used and are well described in the literature...

The results of phylogenetic analyses revealed that the family of plant PDI may comprise of at least eight different subfamilies with varying numbers and positions of active centers while retention signals in the endoplasmic reticulum may be present or absent. At least one gene has been cloned for each phylogenetic group. Other phylogenetic analyses have indicated that the family of PDI-like proteins consists of ten classes, the first five of which include proteins equipped with two thioredoxin domains. These results indicate complexity and diversity of the family of protein disulfide isomerase in plants...
