With the spread of multidrug-resistant tuberculosis (MDR-TB) strains there is an increasing need for new accurate and cost-effective methods for a rapid diagnostic and drug susceptibility testing (DST), particularly in low-income countries where tuberculosis is hyperendemic. A colorimetric assay using 3-(4, 5-dimethylthiazol-2-yl)-2, 5- diphenyltetrazolium bromide (MTT) has been suggested as a ...
مقدمه: از جمله مهم ترین گیرنده هایی که در بیماری هپاتوسلولار کارسینوما بیان بالایی پیدا می کنند، می توان به گیرنده های آسیالوگلیکوپروتئین اشاره کرد. با آراستن سیستم های حامل دارویی به لیگاندهای اختصاصی این گیرنده می توان اتصال آن ها را با سلول و در نتیجه جذب آن ها را به سلول های هپاتوما افزایش داد. این کار سبب کاهش عواض دارو در اندام های غیر هدف و افزایش اثربخشی دارو می شود. هدف از مطالعه ی حاض...
background and objectives: ziziphora clinopodioides is a perennial herb and grows widely in west and northwest of iran. the aerial parts are used as appetizer, carminative and antiseptic as well as for the treatment of medical conditions such as high blood pressure, asthma hyperhidrosis, palpitation and insomnia methods: the aerial parts of ziziphora clinopodioides lam. were extracted by ethano...
BACKGROUND The chromogenic assay based on MTT bioreduction was adapted to Proteus mirabilis viability estimations. We primarily intended to use the assay for the evaluation of novel antimicrobial compounds, including structures with possible permeabilizing activity. Therefore, the influence of basic permeabilizing agents like Triton X-100 and EDTA upon the MTT assay was studied. METHODS 3-(4,...
The aim of this study was to compare four in vitro cytotoxicity assays and determine their ability to detect early cytotoxic events. Two hepatoma cell lines, namely HTC and HepG2 cells, were exposed to cadmium chloride (0-300 microM) for 3, 5 and 8 h. Following exposure to the toxic metal cytotoxicity was determined with the lactate dehydrogenase leakage assay (LDH), a protein assay, the neutra...
MTT assay is commonly used to assess the cellular cytotoxicity caused by anticancer drugs in glioblastomas. However, there have been some reports insisting that MTT assay exhibited non-specific intracellular reduction of tetrazolium which led to underestimated results of cytotoxicity. Here, we examine whether or not MTT assay can lead to incorrect information regarding alcohol-induced cytotoxic...
