background and objectives: some of the human papillomaviruses (hpvs) can infect genital tracts and are sometimes associated with anogenital tract cancers. hpvs induced cervical cancers through the expression of e6 and e7 genes by inactivating the tumor suppressor proteins. in this study, e6 and e7 genes were chosen in order to construct an expression vector which is able to express target prote...

This study explores the methodology of various experimental vaccines and their immunogenicity outcome in detail. The idea is to give to the reader a picture of the research methodology behind vaccine development that was used in this research. The novelty of this study bases on the demonstration of the cause and effect of antibodies produced against bacterial and viral proteins (immunogens) as ...

haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. the disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. despite the availability of new and more powerful antibiotics children with hib meningitis still suffer from high mortality or morbidity. the emergence of multir...

background: sequence variations in glycoproteins of influenza virus surface impel us to design new candidate vaccines yearly. ectodomain of influenza m2 protein is a surface and highly conserved protein. m2e in influenza vaccines may eliminate the need for changing vaccine formulation every year. objectives: in this study, a recombinant baculovirus containing m2e and cholera toxin subunit b fus...

background studies showed that hbv vaccination and consequent level of antibody are not completely adequate among dentists despite performance of highly exposure prone procedures. objectives the objectives of the study were to evaluate the levels of responsiveness to hbv vaccine and to determine the occupational factors associated among dental staff. materials and methods in total, 1612 dental ...

abstract acute diarrhea with severe dehydration has been a major worldwide cause of death in children younger than 5 years of age. etiological studies of gastroenteritis have shown that rotavirus causes 40–50% of acute diarrhea among infants and children in both developing and developed nations. numerous epidemiologic studies in the us and the world health organization have documented the clini...

nonencapsulated, nontypeable hemophilus influenzae (nthi) remains an important cause of acute otitis and respiratory diseases in children and adults. nthi bacteria are one of the major causes of respiratory tract infections, including acute otitis media, cystic fibrosis, and community-acquired pneumonia among children, especially in developing countries. the bacteria can also cause chronic dise...

background preventing the seasonal or pandemic outbreak of influenza can be powerful and cost-effective. objectives in this study, we constructed a novel virus-like particle (vlp) platform that contains two hemagglutinin (ha) subtypes and evaluated immunogenicity of constructed vlp in mice. materials and methods this recombinant candidate vaccine model resulted in the expression of two has of h...
