To interpret pharmacokinetic (PK) data of biotherapeutics, it is critical to understand which drug species is being measured by the PK assay. For therapeutic antibodies, it is generally accepted that "free" circulating antibodies are the pharmacologically active form needed to determine the PK/pharmacodynamic (PD) relationship, safety margin calculations, and dose projections from animals to hu...
ABSTRACT: Actinomycetes are one of the important secondary metabolite producers. Researchers focused on exclusive marine areas for isolation and identification actinomycetes. The present study Nocardiopsis dassonovillei (ON627850) from TS Pettai region. potential strainTSP1 showed effective antibacterial activity against Haemophilus influenza. TSP1 isolates IC50 value 75.22 μg/ml antioxidant de...
BACKGROUND A drug-induced apoptosis assay has been developed to determine which chemotherapy drugs or regimens can produce higher cell killing in vitro. This study was done to determine if this assay could be performed in patients with recurrent or metastatic breast cancer patients, to characterize the patterns of drug-induced apoptosis, and to evaluate the clinical utility of the assay. A seco...
Helicobacter pylori (H. pylori) infection is closely related to various gastroduodenal diseases. Virulence factors and bacterial load of H. pylori are associated with clinical outcomes, and drug-resistance severely impacts the clinical efficacy of eradication treatment. Existing detection methods are low-throughput, time-consuming and labor intensive. Therefore, a rapid and high-throughput meth...
BACKGROUND The WHO recently has recommended the GenoType MTBDRplus version 1.0 and MTBDRsl version 1.0 assays for widespread use in countries endemic with drug-resistant tuberculosis. Despite this, these assays have rarely been evaluated in China, where the burden of drug-resistant tuberculosis is among the highest globally. METHODS Mycobacterium tuberculosis clinical isolates were obtained b...
We implemented a simple, sensitive, objective, and rapid cellular assay to reveal the antifungal activity of a novel class of glucan synthase inhibitors. The assay, especially useful for early drug discovery, measures the transformation of Candida albicans from the yeast form to the hyphal form. Test compounds were ranked by potency (50% inhibitory concentration) and efficacy (percent inhibitio...
BACKGROUND & OBJECTIVES Multiple drug resistance (MDR) among Mycobacterium tuberculosis poses a serious therapeutic problem. Early detection of MDR can be valuable but the conventional drug susceptibility tests take 4-6 wk time after the laboratory isolation of M. tuberculosis. The bacterial phage assay has been reported as a rapid tool for rifampicin susceptibility testing of tubercle bacilli ...
Rapid identification of drug-resistance in Mycobacterium tuberculosis infections is crucial for early treatment and control of transmission. The MTBDRplus assay is potentially a practical and rapid alternative to the slower phenotypic drug susceptibility testing (DST) for detection of drug resistant tuberculosis (TB). The purpose of this study was to determine the diagnostic accuracy of the MTB...
