we aimed to develop a cost-effective and robust method to predict drug resistance in individualpatients. representative tissue fragments were obtained from tumors removed from femalepatients, aged 24-74 years old. the tumor tissue was taken by a histopathology’s or a surgeonunder sterile conditions. cells obtained by enzymatic dissociation from tumor after surgery, werecultured as a monolayer f...

Biofilms are at the root of many infections largely because they are much more antibiotic resistant than their planktonic counterparts. Antibiotics that target the biofilm phenotype are desperately needed, but there is still no standard method to assess biofilm drug susceptibility. Staphylococcus epidermidis ATCC 35984 biofilms treated with eight different approved antibiotics and five differen...

Cell proliferation can be described as the process in which cells reproduce themselves by growing and then dividing into two equal copies. The cancer cell differs from the normal cell in a sense that it is aberrantly regulated. Failure to regulate functions of biomolecules that are necessary for survival, proliferation, differentiation as well as expression of many cell-type functions leads to ...

Accurate prediction of the adverse effects of test compounds on living systems, detection of toxic thresholds, and expansion of experimental data sets to include multiple toxicity end-point analysis are required for any robust screening regime. Alamar Blue is an important redox indicator that is used to evaluate metabolic function and cellular health. The Alamar Blue bioassay has been utilized ...

Two colorimetric methods that use Alamar Blue or 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) for assaying the in vitro activities of antifungal agents have been described. We report that both tests performed similarly when the antifungal activity of amphotericin B against Candida albicans was determined. However, only the MTT test generated interpretable data when Asp...

BACKGROUND Royal jelly is a nutritious substance produced by the young nurse bees and contains significant amounts of proteins which are important for cell growth and proliferation. The aim of this study was to evaluate the effect of royal jelly as an alternative to fetal bovine serum (FBS) in cell culture using cell proliferation assays and live cell imaging. MATERIALS AND METHODS MRC-5 cell...

Resin composite materials that are used to restore tooth cervical lesions associated with gingival recessions can hamper healing after root coverage surgeries. This study evaluates the in vitro cytotoxic effect of five resin composites (two commercial and three experimental) on oral mesenchymal stem cells (MSCs) and the persistence of stemness properties in high passage MSCs. Sorption and solub...

Senile plaques, a neuropathological feature of Alzheimer's disease, consist mainly of insoluble aggregates of pamyloid protein I I I . Using rat pheochromocytoma PC12 cells as an irr vitro model. i t has been shown that 8-amyloid potently inhibits the reduction of MTT 12.31. The cellular reduction of M 7 T is thought to be mediated by the mitochondrial respiratory chain, although other NAD(P)H ...
