Metabolic energy preferentially produced by glycolysis was an advantageous metabolic phenotype of cancer cells. It is also an essential contributor to the progression of multidrug resistance in cancer cells. By developing human breast cancer MCF-7 cells resistant to doxorubicin (DOX) (MCF-7/MDR cells), the effects and mechanisms of 2-deoxy-D-glucose (2DG), a glucose analogue, on reversing multi...

Trends of rising rates of resistance in Pseudomonas aeruginosa make selection of appropriate empirical therapy increasingly difficult, but whether multidrug-resistant (MDR) P. aeruginosa is associated with worse clinical outcomes is not well established. The objective of this study was to determine the impact of MDR (resistance to three or more classes of antipseudomonal agents) P. aeruginosa b...

BACKGROUND Multidrug-resistant tuberculosis (MDR-TB) is posing a great threat to global TB control. The burden in Zambia is not well defined because routine surveillance data are scarce. We reviewed national MDR-TB data for the last decade to inform future public health policy with respect to MDR-TB in Zambia. METHOD Retrospective review of national surveillance of MDR-TB data, TB programme a...

P-glycoprotein, encoded by the multidrug resistance (MDR)-1 gene, expels various drugs from cells resulting in multidrug resistance. We found previously that interleukin-2, a lymphocyte-activation cytokine, induces P-glycoprotein expression on lymphocytes. Lymphocyte activation involves adhesion with the extracellular matrix, such as hyaluronan, through adhesion molecules on lymphocytes. We inv...

Pre-clinical studies of multidrug resistance (MDR) usually address severe resistance, yet moderate MDR is already clinically-impeding. The purpose of this study was to characterize moderate drug resistance in human colon cancer, and it's modulation by fluoxetine. In vitro fluoxetine enhanced doxorubicin's cytotoxicity (10-fold), increased doxorubicin's intracellular accumulation (32%) and decre...

The increasing prevalence of multidrug-resistant Klebsiella pneumoniae strains isolated from hospitals shows the limitation of recent antibiotics used for bacterial eradication. In this study, 81 K. pneumoniae isolates were collected from three hospitals in Tehran. Antibiotic susceptibility test showed the highest rates of resistance to cefotaxim (85.5%) and ceftazidime (78.3%), and the lowest ...

BACKGROUND Treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. The aim of this study was to determine the multidrug resistance (MDR) pattern of the bacteria causing chronic sinusitis in north of Iran. METHODS This cross-sectional study was carried out on patients with chronic sinusitis. Bacterial susceptibility to antimicrobial agents was determined...

Multidrug resistance (MDR) proteins serve as transporters for chemical compounds, small molecules like antibiotics in almost all species from bacteria to higher eukaryote. They provide the resistance against antibiotics and agrichemicals for the cells like cancer, fungi and parasite, etc. Therefore, the research on MDR protein is essential and important in medical, agricultural and scientific f...

Acinetobacter species have become important pathogens in health care settings and are now responsible for substantial mortality and mortality. The resistance among Acinetobacter spp. has also been continuously rising since 2000. Multidrug-resistance (MDR), is defined as simultaneous resistance to fluoroquinolones, aminoglycoside, and third-generation cephalosporins. Data reviewed from Thailand’...

Continuous deployment of antifungals in treating infections caused by dimorphic opportunistic pathogen Candida albicans has led to the emergence of drug resistance resulting in cross-resistance to many unrelated drugs, a phenomenon termed multidrug resistance (MDR). Despite the current understanding of major factors which contribute to MDR mechanisms, there are many lines of evidence suggesting...
