The purpose of this study was to prepare stable polymer-liposome complexes using a new, improved one-pot method. Complexes prepared by the conventional method were used as reference. combines vesicle formation and complexation with polymer in single step allowing for fewer steps compared thin-film followed coating. This has possibility complexing on surface within aqueous core liposomes. Soya p...

RNA interference technology is an ideal strategy to elucidate the mechanisms associated with human CD34(+) hematopoietic stem cell differentiation into dendritic cells. Simple manipulations in vitro can unequivocally yield alloreactive or tolerogenic populations, suggesting key implications of biochemical players that might emerge as therapeutic targets for cancer or graft-versus-host disease. ...

ortho-Quinones are produced in vivo through the oxidation of catecholic substrates by enzymes such as tyrosinase or by transition metal ions. Neuromelanin, a dark pigment present in the substantia nigra and locus coeruleus of the brain, is produced from dopamine (DA) and norepinephrine (NE) via an interaction with cysteine, but it also incorporates their alcoholic and acidic metabolites. In thi...

Background: Sperm mediated gene transfer was approved for producing transgenic animals. There are many studies which reported different success rate by this procedure. Failure in this project mostly is returned to transfection and stability of transferred genes. The other problem that may contribute in project failure may return to the testicular damages which occur at the time of transfection,...

Objective(s): Protection against leishmaniasis, in the murine model, is dependent on developing a potent CD4+ mediated Th1 type response. Liposomes can be applied as immunoadjuvants to stimulate immune responses to different antigens. In the present study, it was investigated whether DOTAP liposomes having SLA and imiquimod adjuvant, can induce a Th1 response and prote...
