when pooled immunoglobulin g (igg) from patients with multiple sclerosis (ms) was used to probe a human fetal spinal cord λgt 11 cdna library, the igg was found to bind to a predicted epitope of human mitochondrial nd4 sequence. to investigate the involvement of the nd4 as an autoantigen in ms, we determined the presence of specific antibody in the serum of ms patients and serum samples of some...

A capillary electrophoresis method was used for assay of some degradation products of carvedilol. The optimized parameters were as; running buffer 80 mM acetate dissolved in methanol/ethanol mixture (65:35 v/v), applied voltage of 19 kV, temperature is 20 ºC and the wavelength range of 200-350 nm. The results indicate that the proposed CE method could effectively separate carvedilol from its de...

A passive hemagglutination test (PHA) was developed for detecting antibodies to human immunodeficiency virus type 1 (HIV-1) utilizing sheep erythrocytes cross-linked with purified envelope glycoprotein (gp160) of HIV-1. In an analysis of 216 human serum samples, 100% correlation was observed in 86 reactive and 124 nonreactive serum samples between PHA and commercial enzyme-linked immunosorbent ...

Pemphigus is an autoimmune disease that causes blistering of human epidermis. We have recently shown that autoantibodies in the serum of three pemphigus patients bind to desmosomes (Jones, J. C. R., J. Arnn, L. A. Staehelin, and R. D. Goldman, 1984, Proc. Natl. Acad. Sci. USA., 81:2781-2785), and we suggested that pemphigus blisters form, at least in part, from a specific antibody-induced disru...

micrornas constitute a group of small non-coding rnas that negatively regulate gene expression. aside from their contribution to biological and pathological pathways, altered expression of micrornas is reported in bio-fluid samples, such as serum. to employ serum's micrornas as potential biomarkers, it is crucial to develop an efficient method for microrna quantification, avoiding pre-analytica...

human t-cell lymphotropic virus type-i (htlv-i) was the first human retrovirus associated with malignancy.  the prevalence of htlv-i infection varies significantly in different regions of the world.  in this study, the prevalence of htlv-i infection among ethnic jews living in shiraz, south of iran, was investigated. 286 blood samples were obtained.  htlv-1 antibody assay on serum samples was d...

monkeys are important experimental models for investigating human diseases. the aim of this study was to survey the alimentary tract parasites among imported vervet monkeys (cercopithecus aethiops) to iran. fecal samples were collected from 40 vervets imported from tanzania to razi vaccine and serum research institute of iran. fecal samples were assessed by direct smear and telman sedimentation...

Background: The present study was carried out on the human population of Kashmir valley to evaluate the status of the biochemical parameters of infected population. Materials and Methods: Blood samples were collected from 514 individuals, 298 (57.97%) males and 216 (42.02%) females, 187 (36.38%) were found sero-positive for human toxocariasis. Results: Alkaline phosphatase level was found highe...
