conclusions chaharmahal and bakhtiari province could be categorized as a low endemic region for hepatitis b infection, with a seroprevalence similar to that in other provinces of western iran. vaccination seems to influence its decrease, especially in adolescents and youth. more surveillance and attention to risk factors are suggested to identify high-risk groups and to implement vaccination. r...

transforming growth factor atpha (tgf-a), parathyroid hormone-tike proteins (pthlp) and oncogene p53 proteins have all been demonstrated in a variety of human tumors anil have been implicated as causes of tumor cell aggressiveness. the present study determined the existence of these peptides and their immunohistochemicat profiles in ameloblastomas. odontogenic keratocysts and dentigerous cysts ...

abstract objective the history of the studies on blood groups dates back to early 20th century. more than 600 antigenic structures were detected among 29 blood groups. however, abo and rh antigenic structures were taken into consideration in transfusion medicine. frequency of the blood groups in a community helps the individuals in need and blood bank employees, which could be related to some d...

indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of h. contortus. plate elisa was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. indirect plate elisa was able to demonstrate...

Background: Cystic echinococcosis (CE), also known as echinococcosis/hydatidosis, is one of the most important parasitic diseases in the world. It enhances both humoral and cellular (Th1 and Th2) responses in infected host. Different antigens of the worm may favor the Th1 or Th2 immune responses in CE patients. Objective: To evaluate the humoral and cellular immune responses of Balb/c mice agai...

Immunotherapy with genetically engineered T-cells that express the chimeric antigen receptor (CAR) has raised hopes for the treatment of pediatric malignancies. Although CAR T-cell development is on a fast-moving pace and evolution, the context of exploring novel targetable antigens has been neglected. In this review study, we analyze the prominent hematologic antigens targeted by engineered T-...

 Purpose. To determine antigenic identity immunodominant proteins different genovariants B. isolated by gel chromatography electrophoresis.
 Materials methods. Culture filtrates isogenic var...

Background : Production of monoclonal antibodies to Leishmania antigens assists the identification and characterization of these organisms. Objective: Production of monoclonal antibodies against epitopes on the gp63. Methods: Two murine monoclonal antibodies to gp63 were produced and characterized. The reactions of both antibodies with soluble leishmanial antigens, purified gp63 and truncated r...
