Multidrug-resistant tuberculosis (MDR-TB) is a serious problem in the former Soviet Union and may appear during TB treatment. We aimed to estimate the prevalence of, timing of and factors associated with MDR-TB diagnosis during TB treatment in Moldova, which was part of the former Soviet Union. We analysed data on 3 754 confirmed non-MDR-TB cases (between January 1, 2007 and December 31, 2010) ...

BACKGROUND & OBJECTIVE P-glycoprotein (P-gp) mediated classical drug resistance and inhibition of the apoptotic pathway are the two mostly investigated mechanisms of multidrug resistance (MDR). Coexpression and interaction of MDR-related factors result in pleiotropic drug resistance in cancer cells. This study was to investigate the correlation of expressions of multiple MDR-related factors, su...

there are increasing reports of emergence of multiple drug resistant (mdr) acinetobacter spp in the world; however there are a few reports in our country. 145 a. baumannii isolates from distinct wards and children's medical center (cmc) in tehran were studied in order to find the profile of antibiotic resistance among them. 40.6% (59/145) of a. baumannii isolates were identified as mdr. overall...

Despite the increasing prevalence of multiple-drug-resistant (MDR) Pseudomonas aeruginosa, the factors predictive of MDR have not been extensively explored. We sought to examine factors predictive of MDR among patients with P. aeruginosa respiratory tract infections and to develop a tool to estimate the probability of MDR among such high-risk patients. This was a single-site, case-control study...

MiRNAs may promote or inhibit tumor recurrence and drug resistance. MiR-139-5p is reportedly downregulated in colorectal cancer patient samples, but it is unknown whether and how miR-139-5p regulates drug resistance. Cancer stem cells (CSCs) are postulated to be important promoters of multiple drug resistance (MDR). In this study, we established a MDR cell model which strongly expressed the CSC...

OBJECTIVE To study MDR-TB isolates and to identify primary and secondary resistance at microbiology laboratory Aga Khan University, Karachi, Pakistan. METHODS All samples positive for Mycobacterium tuberculosis (MTB) received during January - September 2004 were reviewed for drug resistance pattern as well as for history of previous antituberculous drugs exposure. RESULTS Out of 216 Mycobac...

The finding that chloroquine resistance can be partially reversed by verapamil, an inhibitor of P glycoprotein–mediated transport in multiple drug-resistant (mdr) mammalian tumor lines, led to

conclusions this study represented an increasing rate of mdr p. aeruginosa in burn and wound samples. efflux mexab genes were detected in all mdr and pdr strains. the p. aeruginosa strain isolated from burn cases showed higher drug resistance and pdr resistance was only noted in a burn sample. materials and methods one-hundred and fifty p. aeruginosa were isolated from burn and wound infections...
