Cytotoxicity of 5-ALA-conjugated bismuth oxidenanoparticles on KB cell line

Introduction: In recent years, bismuth-based nanomaterials have been widely used in medical researches as imaging, drug delivery and x-ray radiosensitizing agents. Due to their anti-microbial effects against Helicobacter pylori (HP), bismuth colloidal compounds are used to treat various types of diseases such as chronic gastritis. Despite their advantages, bismuth-based compoun...

B12 and Folate Concentrations in Opium Addicts Compared to Healthy Subjects: A Case Control Study from Kerman Coronary Artery Disease Risk Study

Background: Opium addiction is a global problem which has implicated many societies. Opium addiction and drug abuse is related to harmful consequences which affect life style, biochemical factors, and vitamins values, and also is considered as a risk for heart diseases. Folate and B12 levels are related to homocysteine and studies about their levels in opium addicts are controversial; therefore...

Docetaxel delivery using folate-targeted liposomes: in vitro and in vivo studies

Objective(s): Folate-targeted liposomes have been well considered in folate receptor (FR) overexpressing cells including MCF-7 and 4T1 cells in vitro and in vivo. The objective of this study is to design an optimum folate targeted liposomal formulations which show the best liposome cell uptake to tumor cells.Material and Methods: In this study, we prepared and characterized different targ...

Cytotoxicity of folate-Pseudomonas exotoxin conjugates toward tumor cells. Contribution of translocation domain.

Folate-protein conjugates can be nondestructively delivered into a cell's cytoplasm via folate receptor-mediated endocytosis if (i) the target cells express a folate-binding protein, and (ii) if the folate is linked to its attached protein at a site that does not interfere with receptor recognition. Because such conjugates have been observed to remain in endosomal compartments for extended peri...
