A high prevalence of antibody to cag A has been observed in H. pylori seropositive patients (HP+) living in developed countries. This is felt to be correlated with the development of serious sequelae of this infection.  We examined the sero-prevalence of antibody to cag A and other specific H. pylori antigens in symptomatic and asymptomatic individuals living in Kashan.Sera from 37 patients who...

background helicobacter pylori infection is a common infection that affects human beings. this infection also affects children. different diagnostic methods such as serology, stool antigen detection, rapid urease test and histology are used to detect this microorganism. objectives the aim of this study was to determine the correlation between serology and histology/rapid urease test. patients a...

the aim of this study was to evaluate an enzyme - linked immunosorbent assay (elisa) for the detection of anti - helicobacter pylori (h. pylori) specific igg antibodies in specimens of oral fluid. all subjects over the age 18 years undergoing endoscopy for any reason were asked to participate in the study. two groups of 44 patients in each were selected as hp+ and hp-. at the same time, 5 milli...

anti-n-methyl-d-aspartate-receptor (nmda-r) encephalitis is a new autoimmune disorder, often paraneoplastic in nature, presenting with complex neuropsychiatric symptoms. diagnosed serologically, this disorder is often responsive to immunosuppressant treatment. we here in report the case of a 56-year-old man with anti nmda-r encephalitis presenting initially with disorientation and hallucination...

An external force-assisted near-field illumination biosensor (EFA-NI biosensor) detects a target substance that is propelled through an evanescent field by an external force. The target substance is sandwiched between an antibody coupled to a magnetic bead and an antibody coupled to a polystyrene bead. The external force is supplied by a magnetic field. The magnetic bead propels the target subs...

Infectious Bovine Rhinotracheitis is a highly contagious disease caused by the bovine herpes virus-1 (BoHV-1), resulting in significant losses to livestock around the world. BoHV-1 is a major pathogen of cattle, primarily associated with respiratory/genital tract infections and abortion. In the present study, we determined the presence of antibodies in 120 serum samples of cattle with the histo...
