hepatitis b surface antigen is the first genetically engineered vaccine licensed for human use. various strategies have been proposed to obtain a vaccine that would bypass the need for injection. in this study, a non-toxic portion of heat-stable enterotoxin of escherichia coli that is capable of adhering to epithelial cells was inserted at amino acid position 112 of hepatitis surface antigen. t...
mutations in the human hepatitis b virus (hbv) genome contribute to its escape from host immune surveillance and result in persistent infections. the aim of this study was to characterize the molecular variations of the surface gene and protein in chronically-infected patients from the southern part of iran. the surface genes from 12 hbv chronic carriers were amplified, sequenced and ...
Abstract Background: Naturally occurred hepatitis B virus (HBV) with surface mutations in a variety of chronic hepatitis B (CHB) patients who have received no vaccine or HBIG bearing substitutions in surface protein, have been reported. Objectives: Current knowledge concerning the prevalence of these naturally occurring surface antigen mutations among Iranian carriers is limited. Patients and M...
objectives : squamous cell carcinoma (scc) is the most common malignant neoplasm of the oral cavity and a public health threat. tumor progression is believed to be influenced by angiogenesis as well as tumor cell proliferation; however, the correlation of these two factors in tongue scc still remains unclear. this study aimed to assess the correlation of these two factors in tongue scc. materia...
Crystalline arrays of proteinaceous subunits forming surface layers (S-layers) are now recognized as one of the most common outermost cell envelope components of prokaryotic organisms. The surface layer protein of Lactobacillus acidophilus ATCC4356 is composed of a single species of protein of apparent molecular weight of 43-46 KDa. Considering the Lactobacillus acidophilus ATCC4356 having the ...
asymptomatic malaria (asm) has been implicated in the development of hemolytic crisis in infected sickle cell anemia (sca) patients worldwide. this study surveyed steady state sca nigerian patients for asm to investigate the influence of malaria prevention behaviors and age on parasitaemia and multiplicity of infection (moi). a total of 78 steady sca patients aged 5 – 27 years on routine care a...
