Deamidated gliadin peptide antibodies have recently been suggested as reliable tools for celiac disease (CD) diagnosis. We compared their utility for diagnosis CD in comparison to the routinely used anti-endomysial, and anti-tissue transglutaminase antibodies. We studied 65 patients (17 men, 48 women; age range, 17- 63 years) who underwent intestinal biopsy because of clinical suspicion of smal...

BACKGROUND Celiac disease (CD) is a common genetically transmitted immune mediated disease. METHOD Seventy three type 1 DM patients attending the Diabetes, Metabolic and Endocrinology outpatient clinic were recruited in the study. Thorough history taking and medical examination were done. They were screened for the prevalence of celiac disease by ELISA for coeliac disease antibodies against t...

Background We aimed to investigate the frequency of celiac disease in children with β-thalassemia major (B-TM) in Shiraz, southern Iran. Materials and Methods In this study, the prevalence of celiac disease in children with B-TM was evaluated. Children with BTM were screened for celiac disease by ant-tissue transglutaminase (anti-tTG) IgA antibody, IgA level and anti-tTG IgG. A total o...

Introduction: Toxic effects of pesticides are commonly associated with reactive oxygen species damage and pentoxifylline a phosphodiesterase inhibitor is a drug well known for antioxidant properties. The purpose of this study was to evaluate the oxidative damages following a subacute exposure to malathion, an organophosphorus insecticide and pentoxifylline's ability to counteract these effect...

Results: Of these patients, 141 (92.8%) had a positive tTG-IgA and 11 (7.2%) had a negative result. Eighty-one (53.3%) did not have an EGD performed due to patient or legal representatives declining. Of the 71 who had a biopsy, the result of the tTG-IgA in 29 (40.8%) was a true positive, 35 (49.3%) a false positive, 2 (2.8%) a true negative, and 5 (7.0%) a false negative. The sensitivity was 85...

BACKGROUND The sensitivity and specificity of current antihuman tissue transglutaminase (tTG) IgA assays used to detect celiac disease reportedly approach 100%. In addition, the sensitivity of new generation deamidated gliadin peptide (alpha-DGP) antibody assays has also been reported to be similar to the tTG IgA assays. In routine clinical practice, however, the sensitivities and specificities...

More than twenty genes are required for the correct initiation, spacing, and morphogenesis of trichomes in Arabidopsis. The initial selection of trichome precursors requires the activity of both the GLABROUS1 (GL1) and TRANSPARENT TESTA GLABROUS (TTG) genes. The GLABRA2 (GL2) gene is required for subsequent phases of trichome morphogenesis such as cell expansion, branching, and maturation of th...

Coeliac Disease (CD) is an immune-mediated systemic disorder elicited by the ingestion of gluten. Small-bowel biopsies and histology has been the gold standard for diagnosing CD. The modified ESPGHAN guidelines recommend that in symptomatic children with anti-tissue-Transglutaminase (tTG) titre of > 10 times Upper-Limit-of-Normal (ULN), diagnosis of CD can be made without small-bowel biopsies. ...

A novel electrochemical immunosensing strategy for the detection of antibodies to tissue transglutaminase (tTG) in human serum is presented. The proposed immunosensor consists of the immobilization by physical adsorption of tTG from guinea pig liver on graphite-epoxy composite (GEC) electrodes. After the reaction with the human serum (containing the specific antibodies in the case of celiac dis...
