PURPOSE To evaluate the clinical significance of 5-S-cysteinyldopa (5-S-CD), a major intermediate in melanin synthesis, as a potential diagnostic tumor marker for uveal malignant melanoma. METHODS The levels of 5-S-CD in the serum were measured by high-performance liquid chromatography in 16 patients with primary uveal melanoma. The levels of 5-S-CD were also measured in both aqueous and vitr...

aim : this study evaluated serum levels of zinc in patient with cd compare to healthy subjects. background : celiac disease (cd) is characterized by small intestinal malabsorption of nutrients as a consequence of ingestion of wheat gluten. zinc is an essential trace element that it has vital biological functions. patients and methods : sera of 30 celiac cases and 30 healthy normal cohorts as co...

BACKGROUND Serum anti-glycan antibodies are a promising tool for differential diagnosis, disease stratification and prediction of Crohn's disease (CD). To investigate possible heritability of the markers we assessed the presence of serum anti-glycan antibodies in affected and unaffected relatives of patients with CD. METHODS Serum samples of 169 IBD patients of the German inflammatory bowel d...

Genetically engineered seedlings obtained from self-fertilized transgenic tobacco (Nicotiana tabacum) contained and expressed the mouse metallothionein and kanamycin resistance marker genes and were more tolerant to cadmium stress than untransformed controls. Cadmium accumulation in leaves of transgenic seedlings exposed to a low, field-like Cd concentration (0.02 micromolar) was about 20% lowe...

OBJECTIVE To identify Hodgkin's and Reed Sternberg like cells by a single Immunomarker (Ki-1; CD-30) and to highlight diagnostic specificity of these cells in Hodgkin's disease, as these cells are frequently encountered in other lymphoproliferative disorders on H&E sections. METHODOLOGY Seventy-nine histologically diagnosed cases of lymph node biopsies (59 cases of Hodgkin's disease, 15 cases...

BACKGROUND The safety of opiate use for patients with Crohn's disease (CD) has long been a concern. The recent Crohn's therapy, resource, evaluation, and assessment tool (TREAT) registry update has added to these concerns by demonstrating an association of opiate use with an increased risk of infection and death in CD. While the association is clear, the relationship of opiates to these negativ...

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...
