A rapid colorimetric, microplate based nitrate reductase assay (NRA) method for minimum inhibitory concentration (MIC) determination of clinical isolates of Mycobacterium tuberculosis was compared with the microplate Alamar Blue assay (MABA), presently in vogue. Reproducible results were obtained in 7 days by NRA. The NRA method was found to be inexpensive, suitable for MIC determination agains...

Large interindividual variance has been observed in sensitivity to drugs. To comprehensively decipher the genetic contribution to these variations in drug susceptibility, we present a genome-wide model using human lymphoblastoid cell lines from the International HapMap consortium, of which extensive genotypic information is available, to identify genetic variants that contribute to chemotherape...

An alamarBlue-based growth inhibition assay has been adapted for the thermosensitive and slow-growing pathogen Mycobacterium ulcerans. The standardized test procedure enables medium-throughput screening of preselected compound libraries. Testing of a set of 48 azoles with known antifungal activity led to the identification of an imidazole antifungal displaying an inhibitory dose (ID) of 9 μM fo...

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...

Albizia amara (Roxb.) B. Boivin has been used historically for the treatment of septicaemia, malignancy, delirium, and convulsions. A decoction made from bark is to treat rheumatism, hemorrhage, some bleeding disorders during pregnancy, as well stomach pain nasal issues. active ingredients like flavonoids, alkaloids, steroids, phenolic compounds, tannins, according early phytochemical screening...

Two novel systems were evaluated for performing indirect kanamycin susceptibility tests on 72 strains of Mycobacterium tuberculosis. The microplate Alamar blue colorimetric method (breakpoint, 2.5 microg/ml) and the Mycobacterium Growth Indicator Tube (MGIT) system (breakpoint, 5.0 microg/ml) both produced 98.6% agreement when compared with the conventional proportion method performed on 7H10 a...

The AlamarBlue assay is based on fluorometric detection of metabolic mitochondrial activity of cells. In this study, we determined the methodology for application of the assay to radiation response experiments in 96-well plates. AlamarBlue was added and its reduction measured 7 hours later. Selection of the initial number of plated cells was important so that the number of proliferating cells r...

In response to the need for rapid, inexpensive, high-throughput assays for antimycobacterial drug screening, a microplate-based assay which uses Alamar blue reagent for determination of growth was evaluated. MICs of 30 antimicrobial agents against Mycobacterium tuberculosis H37Rv, M. tuberculosis H37Ra, and Mycobacterium avium were determined in the microplate Alamar blue assay (MABA) with both...

BACKGROUND Polymers have been considered as important materials in fabrication of microstructures for various medical purposes including drug delivery. This study evaluates polyurethane as material for hollow microstructures preparation. RESULTS Polyurethane microstructures were obtained by interfacial polyaddition combined with spontaneous emulsification and present slightly acid pH values. ...
