Different leukemias express on their plasma membranes particular subsets of the 247 defined cluster of differentiation (CD) antigens, which may resemble those of precursor cells along the lineages of differentiation to mature myeloid and lymphoid leukocytes. The extent of use of CD antigen expression (immunophenotyping) for identification of leukemias has been constrained by the technique used,...

PURPOSE Identification of a 32-kd protein in the bovine retinal pigment epithelium. METHODS A bovine retinal pigment epithelium cDNA library was constructed in the bacteriophage lambda ZAP Express. A monoclonal antibody, designated 21-C3/AV, was used to isolate the cDNA encoding the 21-C3/AV antigen. A positive full-length clone, designated 21-C3RDH/CD, was sequenced. Northern blot analysis w...

BACKGROUND Celiac disease (CD) has emerged as a common, but largely undiagnosed health problem. Numerous studies examined the influence of infant nutrition on the development of diagnosed CD. However, results are still inconsistent. In addition, the effect of infant feeding practices on the development of potential forms of CD might be different. OBJECTIVE The objective was to examine whether...

BACKGROUND AND OBJECTIVE Risk haplotypes have been described in celiac disease (CD), but the influence of native genes on CD in Hispanic Americans is unknown. The aim of the study was to measure the frequency of Amerindian mitochondrial DNA (mtDNA) haplogroups (inherited by the maternal line) in mixed-blood patients with CD from Chile, Argentina, and Uruguay, and to assess the relation between ...

Objective(s): This study aimed to investigate the effect of zinc oxide nanoparticles (ZnO-np) on biofilm formation and expression of the flu gene in uropathogenic Escherichia coli (UPEC) strains. Materials and Methods: Minimum inhibitory concentration (MIC) of ZnO-np was determined by agar dilution method. The effect of MIC and sub-MIC concentrations of ZnO-np on biofilm formation were determin...

BACKGROUND On ingestion of gliadin, the major protein component of wheat and other cereals, the celiac intestine is characterized by the proliferation of crypt enterocytes with an inversion of the differentiation/proliferation program. Gliadins and A-gliadin peptide P31-43, in particular, act as growth factors for crypt enterocytes in patients with celiac disease (CD). The effects of gliadin on...

BACKGROUND Celiac disease (CD) is an autoimmune disease characterized by immunemediated inflammatory damage of the small intestinal mucosa, precipitated by the ingestion of gluten-containing foods. Since human leucocyte antigen DQ2 (HLA-DQ2) is a marker of nonresponsiveness to hepatits B virus (HBV) vaccine, CD may also be associated with this nonresponsiveness. OBJECTIVES The aim of this stu...

Gastrointestinal stromal tumors (GISTs) compose the largest category of well-recognized nonepithelial neoplasms of the gastrointestinal tract (GI). GISTs of the gallbladder are extremely rare tumors. Only four malignant, two benign and one GIST-like tumor of the gall bladder have ever been described. The four malignant GISTs were all positive for CD 117 antigen (c-kit). We present for the first...

Breast milk is the natural nutrition for infants, but in the second half of the first year of life, complementary feeding is needed. Many complementary foods contain gluten, but gluten exposure is associated with the risk of developing celiac disease (CD). CD is a disease with considerable morbidity and mortality. Although CD is associated with certain genetic features, carrying the human leuko...

The CD2 glycoprotein has been implicated in both positive ment of positive selection, the lack of CD2 was associated and negative regulation of T-cell mitogenesis. To study the with defects in proliferative responses and interferon-g proinvolvement of CD2 in T-lymphocyte development and imduction when transgenic thymocytes and mature T lymphomune responses, we have analyzed two lines of CD2-nul...
