of these, the EPISKIN method showed evidence of being a reliable and relevant standalone test for predicting rabbit skin irritation, when the endpoint is evaluated by MTT reduction, and for being used as a replacement (based on the performance of the assay as specified in the annex) for the Draize Skin Irritation Test (OECD TG 404 & Method B.4 of Annex V to Directive 67/548/EEC) for the purpose...

Cytotoxicity of the futuristic nanogenomedicine (e.g., short interfering RNA and antisense) may hamper its clinical development. Of these, the gene-based medicine and/or its carrier may elicit cellular toxicity. For assessment of such cytotoxicity, a common methodology is largely dependent upon utilization of the 3-(4, 5-Dimethyl-2-thiazolyl)-2, 5-diphenyl-2H-tetrazolium bromide (MTT) assay whi...

Glioblastoma is most common and most aggressive cancer of brain. for treatment surgery is first selection and radiation therapy then chemotherapy. The median survival of Patients with GBM is less than a year after diagnosis. Glioblastoma is basically resistant to common cancer treatments. today to improve the response of patients to treatment, a number of strategies such as the use of radiation...

The ability of sperm cells to develop colored formazan by reduction of MTT was used earlier to develop a spectrophotometric assay to determine the viability of sperm cells for several mammalian species. It was the objective of the present study to visualize microscopically the location of the formazan in boar sperm cells. The MTT staining process of boar sperm cells can be divided into a series...

General toxicity, antiproliferative, antibacterial and antioxidant activities of Caulerpa peltata J.V.Lamouroux (Caulerpaceae) collected from Oman Sea were investigated. Dried, ground alga was Soxhlet-extracted with hexane, dichloromethane and methanol successively. The methanol extract was subjected to vacuum liquid chromatography (VLC) fractionation on silica gel using a step gradient of diff...
