The injection of naked plasmid DNA directly into the muscle cells of mice has been shown to induce potent humoral and cellular immune responses. The generation of a cytotoxic T lymphocyte (CTL) response after plasmid DNA injection may involve the presentation of the expressed antigen in the context of the injected myocytes' endogenous major histocompatibility (MHC)-encoded class I molecules or ...

objective: to compare immunogenicity of a recombinant hepatitis b (hb) vaccine in two groups of neonates born in two cities of iran with different geographic and ethnic backgrounds.   materials and methods: ten micrograms of a recombinant hb vaccine was administered under field condition to iranian healthy neonates at 0, 1.5 and 9 months intervals. the subjects consisted of two groups of 290 an...

Protective immuni ty against several species of malar ia parasites has been obtained by vaccinat ion with x-irradiated sporozoites (reviewed in reference 1). The serum of protected animals reacts with the surface membrane of sporozoites and neutralizes their infectivity, which suggests that the effect of the vaccine is at least in part an t ibody mediated. T he membrane-associated protective an...

background and aims: from the past studies, it has been proved that consumption of heavy metals by humans may cause several chronicle problems like cancer, kidney and liver damage, high blood pressure and low blood pressure problems and etc. so, it has become very crucial to remove these heavy metals from industrial wastewater. the aim of this study was to find out a low cost and easy available...

an enzyme electrode was developed using the enzyme sulfite oxidase (ec1.8.3.1) immobilized onto pig intestine. hydrogen peroxide produced was monitored amperometrically. all experimental parameters such as ph, temperature, buffer constituent concentration, were thoroughly investigated and optimized when appropriate. the response to sulfite concentration was linear in the range 5.2´10-6 to 1.02´...
