OBJECTIVE The high prevalence of celiac disease (CD) prompted us to evaluate a new, noninvasive disease screening strategy. The aim was to identify CD in 6- to 8-year-old children for a timely diagnosis, start gluten-free diet (GFD) in compliant subjects, achieve the growth target, and prevent CD complications. METHODS Five thousand subjects were invited to participate in the study. Four thou...

background : antivenom is still widely used in the treatment of envenomation as there are no vaccines or other effective agents available against animal venoms. recently, neurotoxins named birtoxin family have been described from parabuthus transvaalicus and androctonus crassicauda. the aim of the present study was to test the antibirtoxin antibodies for their ability to neutralize the lethal e...

the study was undertaken to answer the question that how many patients with pigmentation of back and arms actually have amyloid deposits in pathology. 44 patients presenting with diffuse pigmentation of back and arms (dpoba) were selected. skin biopsies were performed in all cases from the affected sites. on all formalin fixed and paraffin embedded specimens, the following histochemical stains ...

Chronic changes in blood flow induce an adaptation of vascular caliber. Thus, arteries show inward remodeling after a reduction in blood flow. We hypothesized that this remodeling depends on the crosslinking enzyme tissue-type transglutaminase (tTG). Flow-dependent remodeling was studied in wild-type (WT) and tTG-null mice using a surgically imposed change in blood flow in small mesenteric arte...

Background: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease which is characterized by B-cell abnormality and auto-antibody generation. Since bacterial infections are the most important causes of mortality in these patients, pneumococcal vaccination is recommended for children with SLE. Objective: To investigate humoral immunity and specific-antibody formation in response to a...

Overexpression of 'tissue' transglutaminase (tTG) in the human neuroblastoma cells increases spontaneous apoptosis and renders these cells highly susceptible to death induced by various stimuli. We used immunoprecipitation to identify cellular proteins that interact specifically with tTG in SK-N-BE(2) -derived stable transfectants. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analy...

The addition of 2500 i.u./ml interferon alpha (IFNalpha) for 48 h induced apoptosis, and caused an approx. 4-fold increase in the activity and expression of tissue transglutaminase (tTG), in human lung cancer H1355 cells. However, the increase in mRNA levels for tTG was just 1.6-fold. On the basis of these data, we investigated whether tTG levels may be regulated through regulation of its degra...

background: hepatitis b infection is a major public health problem worldwide. given that immune response towards the vaccine is not perfect, we aimed to evaluate circumstances of immune response in vaccinated students. materials and methods: in this study, 219 medical students of ardabil university of medical sciences were recruited, who had been administered vaccine series for the first time, ...
