the objective of the study was to evaluate the cytotoxic effects of aqueous extract of cucumis melo fruit on human prostate cancer cell line (pc-3) using mtt and neutral red assays. the crude aqueous extract of c. melo was prepared by cold maceration method, filtered, concentrated and tested on pc-3 cell line. dose-dependent cytotoxic activities were exhibited on human prostate carcinoma pc-3 c...

The aim of this study was to evaluate and compare the cytotoxicity induced by two resin-based sealers, 2Seal and AH Plus, in two osteoblast-like cell lines, MG-63 and Saos-2. Using sterile discs of both sealers in complete media, 24- and 72-h extracts were prepared. The extracts were exchanged with Saos-2 or MG-63 cell culture media at 75% confluence, and after 24 h incubation, cell viability t...

zn (ii) is an important regulator of caspase-3, as well as an antioxidant, microtubule stabilizer, growth cofactor, and anti-inflammatory agent. over the past 30 years, many researchers have demonstrated the important role of zn (ii) in a variety of physiological processes, including growth and development, maintenance and priming of the immune system, and in tissue repair and regeneration. in ...

we investigated the effects of 25 mg-porphyrin-fullerene nanoparticles, ( 25 mgpmc16) smart ferroporphyrin nanoparticles, on pc12 cells exposed to oxygen-glucose deprivation/reperfusion. in order to explore its effect on cells under oxygen-glucose deprivation conditions, the cultures were pretreated with 25 mgpmc16 24 hours prior to oxygen-glucose deprivation/reperfusion. to initiate the oxygen...

objective(s) this study was carried out in order to evaluate the effects of electrochemotherapy, electrical pulses and chemotherapeutic drugs on the killing of cancerous cells and their probable synergistic effects. materials and methods electrochemotherapy treatments conducted on mcf-7 cell line derived from human breast adenocarcinoma tumor using four chemotherapeutic drugs including bleomyci...

background: the monoclonal antibody, c595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (gd-cdtpaa) to produce gd-dtpa-c595 and used as specific breast cancer cell line (mcf-7) contrast agents in magnetic resonance imaging (mri).  methods: after incubation of breast cancer cell line (mcf-7), with different contrast agents (g...

Background: The exposure of cell lines to low-dose irradiation leads to changes at molecular level, which may induce adaptive response. We examined radio-adaptive doses effect on human colorectal adenocarcinoma cell line (HT29) and human fetal fibroblasts (MRC5) cell line followed by hyper and hypo fractionation regimes, with main purpose to decrease cell viability in HT29, and at the same time...
