We investigated the effect of epigallocatechin-gallate (EGCG), the main constituent of green tea polyphenols, on human glioblastoma cell lines U-373 MG and U-87 MG, rat glioma cell line C6, and rat nonfunctioning pituitary adenoma cell line MtT/E. Cell viability was determined by assay with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT), and the extent of apoptosis was stud...

Zn(II)-ZMT material development based on natural zeolite mordenite type (ZMT) as a drug carrier for ibuprofen has been explored and assessed. The ion exchange method was carried out to prepare material. XRD, FTIR, FESEM-EDS were used characterize the physico-chemical characteristics of all materials. performance delivery agent also evaluated using loading-release, zeta potential measurement, cy...

OBJECTIVE To filtrate breast cancer resistance protein (BCRP)-mediated resistant agents and to investigate clinical relationship between BCRP expression and drug resistance. METHODS MTT assay was performed to filtrate BCRP-mediated resistant agents with BCRP expression cell model and to detect chemosensitivity of breast cancer tissue specimens to these agents. A high performance liquid chroma...

PURPOSE To compare human urothelial and smooth muscle cells attachment and proliferation using three different matrices; poly lactic-co-glycolic acid (PLGA), PLGA/collagen and human amniotic membrane (hAM). MATERIALS AND METHODS Human urothelial and smooth muscle cells were cultured and examined for expression of urothelium (pancytokeratin and uroplakin III) and smooth muscle cells [desmin an...

3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyltetrazoliumbromide (MTT) assay is a widely used assessment method for the determination of anticancerogenic effects active compounds including plant secondary metabolites. Recently, some important ingredients have been investigated properties on melanoma cancer lines which are most lethal type skin cancer. Although methods DNA assay, 3H-thymidine incorpo...

Objective: Anticancer activities of Schiff bases S1 and S2 against MG-63 human osteosarcoma cells were performed described using an in vitro evaluation employing cytotoxicity apoptosis assay. Methods: used MTT assay to examine the effect compound on cell viability (S1 S2). Cell morphologies IC50 values obtained. The acridine orange (AO)/ethidium bromide (EB) dual staining technique was determin...

BACKGROUND Hyperthermia is used in combination with radiotherapy and/or chemotherapy in the treatment of various types of cancer. Currently, the tumor cell response to hyperthermia is determined largely based on the size reduction of tumor mass, which is insensitive. METHODS We tested the feasibility of bioluminescent imaging (BLI) in evaluation of the tumor cell response to hyperthermia by e...

introduction: the aim of this study was to evaluate the effect of human sperm mtt viability assay on outcome of intracytoplasmic sperm injection. mtt is a tetrazolium salt, routinely used for cell proliferation and cytotoxicity assays. materials and methods: 50μl of processed semen was treated with mtt solution, while the remaining used as the control. meanwhile, 109 donated human oocytes (meta...
