conclusions due to the significant reduction in the mean inactivation dose of colon cancer cells in the presence of gold nanoparticles, it seems that gnps are suitable options to achieve a new approach in order to improve radiotherapy efficiency without increasing the prescribed radiation dose. results cell survival in the presence of gnps was more than 90% and the maximum uptake of gnps was ob...

Background and Objective: The aim of this study was to compare the cytotoxic effects of local probiotic bacteria, including Lactobacillus paracasei, Lactobacillus brevis, while isolated from “Tarkhine” food and the induction of apoptosis in the HT–29 human colon adenocarcinoma cell line and normal fibroblasts. Methods: HT–29 and L–929 cell lines were trea...

Objective(s): The purpose of this study was to investigate cytotoxicity and membrane toxicity effects induced by Mesobuthus eupeus venom (MEV) on the HT-29 cell line. Materials and Methods: To determine the in vitro cytotoxicity via MTT assays, HT-29 (as cancer cell line) and Hek-293T (as normal cell) were treated through different conce...

objective: it is well-known that all living cells emit ultra-weak photon emission (upe), which is due to byproducts of chemical reactions in cell metabolisms. it has been shown that reactive oxygen species (ros) in the cells enhances the upe intensity. the magnitude of such upe is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...
