We present a theoretical study of the effect of surface defects on atomic friction in the stick-slip dynamical regime of a minimalistic model. We focus on how the presence of defects and temperature change the average properties of the system. We have identified two main mechanisms which modify the mean friction force of the system when defects are considered. As expected, defects change the po...
Monoclonal antibodies were produced from naturally infected BALB/c mice. Thirteen hybridomas which were found to produce monoclonal antibodies against surface tegumental antigens of Schistosoma mekongi by ELISA assay were used in this study. The antigen specificities of hybridomas reactive with surface tegumental antigens were characterized and localized by immunoblotting analysis and Avidin-Bi...
Abstract Background and Objective: Hepatitis delta virus is an imperfect virus with RNA and its activity depends on the presence of hepatitis B virus. This virus can lead to acute and chronic diseases in the liver. This study aimed to detect the hepatitis delta virus in blood donors with positive Hepatitis B Surface Antigens (HBsAg). Material and Methods: In this Study, 350 serum sa...
Background and Objectives Polytopic antigens are recently applied for replacing crude antigens, for control of infectious agents. The surface of the Toxoplasma is covered with immunogenic antigens namely surface antigens (SAGs). These antigens possess several immunogenic epitopes, inducing immune responses. Materials and Methods In this study, a DNA construct comprising of sequences encoding ...
Background: Diarrhea caused by Escherichia coli is a major cause of morbidity and mortality in young animals. Few treatment options are available, mainly antibiotic therapy increasingly limited by resistance to commonly used drugs.Objectives: The aim of this work was to develop immunotherapy based on the use of camel VHH antibody fragments, or nanobodies,...
Monoclonal antibodies reactive with myeloid cell surface antigens were used to study evolutionary changes in granulocyte surface antigens from primate species. Certain of these granulocyte membrane antigens are conserved in phylogenetically distant species, indicating the potential functional importance of these structures. The degree of conservation of these antigens reflects the phylogenetic ...
Abstract Background and Objectives Immune platelet refractoriness is a complication of blood transfusion in patients with multiple platelet transfusions. Antibodies against surface antigens, including human platelet antigens (HPAs) and human leukocyte antigens (HLAs), can be produced which can cause the degradation of transfused platelets by macrophages. In this study, the frequency of platele...
