The potential roles of specific antibodies of different immunoglobulin G (IgG) subclasses and IgE in serological diagnosis of cystic echinococcosis (CE) were investigated by an enzyme linked immunosorbent assay (ELISA) based on Antigen 5 (Ag5). Presence of IgG1 was demonstrated in all sera from 58 patients with CE. The most discriminatory and specific(More)
The cellular response to Leishmania major (L. major) is usually evaluated in vivo by the delayed-type-hypersensitivity (DTH) test using leishmanin. Leishmanin can give false-positive reactions in areas where there is a background of leishmaniasis. In a previous study, it was shown that a 56 kDa antigen purified from promastigote and culture supernatant of(More)
Oxytocin (OT) is the first peptide hormone structurally assessed and chemically synthesized in biologically active form. This hormone acts as an important factor in a human reproductive system particularly during pregnancy and lactation in women. So far, different therapeutic roles for OT have been identified as a spectrum from central and peripheral(More)
Reperfusion injury is an inherent response to the restoration of blood flow after ischemia. It is a complex process involving numerous mechanisms occurring in the intracellular and extracellular environments, and it is mediated in part by reactive oxygen species (ROS). The imbalance between the cellular formation of free radicals and cells' capacity to(More)
A series of hybridomas was produced by fusion of SP2/0 myeloma cells with spleen cells of mice immunized with Leishmania major (L. major). The reactivity of secreted monoclonal antibodies (mAbs) was evaluated against available leishmanin antigen by enzyme linked immunosorbent assay. Only one hybridoma designated as 7F9 secreted IgG1 mAb which was shown to(More)
which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Liver plays the role of detoxifier and excreter of destructive agents against body intoxication. Liver injury occurs following by histopathological changes including degen-eration, necrosis, and atrophy of liver parenchymal cells with(More)
In this report we have analysed the peripheral blood lymphocyte of several patients with chronic hepatitis B virus infection with flow cytometry. Based on the presence and absence of the HBeAb, patients were divided into two groups. In both, all the patients were HBsAg positive with normal range of serum alanine aminotranferase (23.9 +/- 17.8). We have(More)
A simple, sensitive, selective, and rapid optical nanobiosensor based on FRET was designed to detect tropane alkaloids as anti-cholinergic agents in natural and transgenic hairy roots extracts of Atropa belladonna. To achieve that, conjugation of tioglycolyic acid capped cadmium telluride quantum Dots, M2 muscarinic receptor (Cd/Te QDs-M2R) and conjugation(More)
OBJECTIVE Pycnodysostosis is a rare autosomal recessive osteochondrodysplasia resulting from osteoclast dysfunction. Growth hormone (GH) secretion impairment and low insulin growth factor 1 (IGF-I) concentrations have been reported in these patients. The present study aims to describe GH effect on linear growth of eight children with pycnodysostosis. (More)
