UNLABELLED The current study was aimed to evaluate the performance of direct 2,3,5-triphenyl tetrazolium chloride assay and direct microscopic observation drug susceptibility assay with indirect Löwenstein-Jensen proportion method directly on Ziehl-Neelsen smear positive sputum specimens. METHODS Direct acid fast bacilli smear positive sputum specimens (n=264) were subjected to isoniazid and ...

New antifungal agents are needed to treat life-threatening fungal infections, particularly with the development of resistance. Surface-active antifungals have the advantages of minimizing host toxicity and the emergence of drug resistance. We have developed a time-dependent drug exposure assay that allows us to rapidly investigate the mechanism of surface-active antifungal drug action. The assa...

Many people suffer from hair loss and abnormal skin pigmentation, highlighting the need for simple assays to support drug discovery research. Current have various limitations, such as being in vitro only, not sensitive enough, or unquantifiable. We took advantage of bilateral symmetry large size mouse whisker follicles develop a novel vivo assay called “whisker follicle microinjection assay”. I...

BACKGROUND AND OBJECTIVE: Candida albicans infection is a problem of growing clinical importance, particularly in immunocompromised populations. This study aimed to investigate the inhibitory effect of carvacrol on the hyphae formation and expression of C. albicans HWP1. METHODS: This cross-sectional study was done over a 6-month period in 2016-2017. Vaginal, mouth and  skin surface swabs were...

Soft agarose culture human tumour colony forming assay for drug sensitivity testing: [3H]-Thymidine incorporation vs colony counting Summary In vitro drug sensitivity testing, both by optical colony counting and by a [3H]-TdR incorporation assay, was performed on human tumour cells proliferating in soft agar cultures. Cells from two different human tumour cell lines, 5 different human tumour xe...

PURPOSE The cloned enzyme donor immunoassay (CEDIA) for buprenorphine is applied for both urine drugs-of-abuse screening and compliance monitoring. Sensitivity, specificity, and optimal cutoff of this assay have differed between studies. This may indicate that cross-reactivity has to be taken into account during assay evaluation. We therefore investigated the performance of the CEDIA buprenorph...

Strong inhibition of the human UDP-glucuronosyltransferase enzymes (UGTs) may lead to undesirable effects, including hyperbilirubinaemia and drug/herb-drug interactions. Currently, there is no good way examine inhibitory effects specificities compounds toward all important UGTs, side-by-side under identical conditions. Herein, we report a new, broad-spectrum substrate for UGTs its uses in scree...
