conclusions thyroid dysfunction was not higher in sle patients compared to healthy individuals. however, anti-tg antibodies were higher in sle patients. it has not yet been established that thyroid function tests should be performed routinely in sle patients. results the mean age of sle patients and controls were 32.16 ± 9.19 and 32.48 ± 9.47 years, respectively (p = 0.821). patients had signif...

A light-addressable potentiometric (silicon) sensor was used in an immunofiltration procedure for the detection of pathogenic bacteria. Yersinia pestis was detected by filtering the cells onto nitrocellulose membranes and then filtering anti-Y. pestis mouse monoclonal antibody and anti-mouse immunoglobulin G-horseradish peroxidase conjugate. For Neisseria meningitidis detection, mouse monoclona...

background: rh (rhesus) is a highly complex blood group system in man deeply rooted in transfusion medicine. isolation of rhd from cord blod, cloning and expression of recombinant rhd antigen in bacterial expression system was the aim of this study. methods: total rnas were extracted from cord blood (o + ).  the quality of rna was determined by electrophoresis. in or­der to obtain coding sequen...

We present a case of a false-positive anti-myeloperoxidase (MPO) antibody result on an ELISA in a patient with anti-thyroid microsomal antibody (TMA)-positive hypothyroidism. A 41-year-old woman presented with dyspnea on exertion. The initial evaluation revealed pericardial effusion associated with hypothyroidism. In addition, microscopic hematuria with normal renal function and positive cytopl...

A competitive enzyme immunoassay (CEIA) was established and compared with other serological techniques for detecting Coxiella burnetii antibody in camels, goats, and sheep. This technique was evaluated because a conjugated anti-camel immunoglobulin was not available to serve as a direct signal for the demonstration of antigen-antibody reaction. A C. burnetii antibody-positive human serum and a ...

to evaluate the correlation of cytomegalovirus (cmv) and coronary artery disease (cad), one-hundred patients with cad and the same number of healthy individuals as a control group were randomly selected and studied for anti-cmv using elisa method. ninety percent of patients and 77 percent of the control group were anti-cmv positive and statistical analysis showed a significant correlation betwe...

anti-neutrophil cytoplasmic autoantibodies have been detected in patients with some autoimmune and vascular diseases such as wegner's granulomatosis, polyarthritis nodosa and systemic lupus erythematosus. indirect immunofluorescence technique has been employed to detect these autoantibodies. by this method, two general patterns of antineutrophil cytoplasmic antibodies were seen: a cytoplasmic (...

background: the prevalence of toxoplasma gondii infection in the blood donors has been poorly studied. the aim of this study was to assess the prevalence of acute and chronic toxoplasmosis in blood products. methods: a total of 250 blood products (112 fresh frozen plasma and 138 packed cells) in the blood transfusion institute, shiraz, iran were tested for spe-cific t. gondii antibodies (igg an...

Antibody to tissue factor apoprotein was adsorbed against gamma-globulin and coupled to horseradish peroxidase; this complex was applied to various rabbit tissues. The distribution of the peroxidase marker then was observed by electron microscopy. We examined fixed or frozen sections, as well as breis of aorta, vena cava, brain, heart, lung, liver, spleen, kidney, bone marrow, mesothelial gut l...
