Research ArticleOpen accessEvery word in the titleCirculation of Multidrug-Resistant (MDR) and Extensively Drug-Resistant (XDR) Mycobacterium Tuberculosis Strains in MexicoCarlos A. Vazquez-Chacon, Armando Martinez-Guarneros, Susana Balandrano Campos et al.Emergence of Extensively Drug-Resistant (XDR) Tuberculosis (TB) is an important public health problem worldwide. In Mexico, the extent of circulation of XDR-TB strains is unknown. Here, the drug-resistance patterns of TB isolates collected in Mexico between 2006 and 2008 were analyzed. Among 137 TB isolates, (58%) were classified as MDR exclusively, (33%) were Pre-XDR and (9%) were assigned as XDR. … …American Journal of Infectious Diseases, Vol. 10, Issue 4 · 7 Jan 2015 · 7,422 accessesView PDF Cite

Review ArticleOpen accessEvery word in the titleMultidrug Resistant Microorganisms (MDR) and Biofilm Producers: A Challenge for Hospital Infectious ControlDaniel Lucio, Elizabeth Proaño, Alberto Bustillos et al.Antimicrobial Resistance (AMR) now represents a major threat to contemporary health care, especially in hospitals, where repeated antimicrobial exposure selects for and facilitates the dissemination of Multidrug-Resistant (MDR) microorganisms. Biofilm growth adds another layer of persistence by increasing microbial tolerance, supporting long-term colonization of medical devices, and worsening clinical and economic outcomes. This narrative review synthesizes evidence on MDR biofilm-forming … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 12 Sep 2026 · 774 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleComputing MDR-Game with Applications to Real DataJimbo Henri Claver, Takeru Suzuki, Jesus Pascal et al.Originally developed for probability and statistic purposes, Multiple Dice Rolling (MDR) game turns out to be useful for many other applications such as complex biological systems and medical research. It has been mainly used to estimate system states that cannot be observed directly. MDR game is affected by noise and fluctuations. It is widely agreed that noise in dynamic systems … …Journal of Computer Science, Vol. 14, Issue 7 · 17 Jul 2018 · 7,789 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMultidrug Resistant Uropathogens among Egyptian Pregnant WomenWafaa Salah Metwally, Walid Mohamed ElnagarUrinary Tract Infections (UTIs) in pregnancy is a common medical problem associated with significant increase in the risk of fetal morbidity and mortality. The effective appropriate antimicrobial agent is a major concern as many effective antimicrobial groups cannot be used due to their potential toxicity to the fetus as well as the increasing rates of Multidrug-Resistant (MDR) strain isolation. This … …American Journal of Infectious Diseases, Vol. 15, Issue 4 · 21 Dec 2019 · 7,487 accessesView PDF Cite

Review ArticleOpen accessIn the keywordsScope and Perspectives of New TB Drugs and VaccinesJaishree Meena, Laxman S. MeenaTuberculosis remains a major threatening infectious disease claiming millions of lives every year; hence increasing the global burden of TB disease. Co-infection with human immuno-deficiency virus and emergence of multi-drug resistant tuberculosis, extremely drug resistant tuberculosis and totally drug resistant tuberculosis enhances deadly effect of tuberculosis. To eliminate TB disease from human population several partnerships are working together like Stop … …American Journal of Infectious Diseases, Vol. 11, Issue 3 · 10 Sep 2015 · 7,943 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsQuercetin, Quercetrin Except Rutin Potentially Increased Pirarubicin Cytotoxicity by Non-Competitively Inhibiting the P-Glycoprotein-and MRP1 Function in Living K562/adr and GLC4/adr CellsWinit Choiprasert, Nathupakorn Dechsupa, Suchart Kothan et al.Problem statement: Quercetin and its glycoside derivatives are increasingly receiving interests as new generation of anticancer molecules and were recognized by multidrug resistant transporters such as P-glycoprotein and MRP1 protein. Of relevance to their use as anticancer agents alone or in combination with other agents, this study aims to analyze the interaction of the compounds with the MDR transporters including … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Mar 2010 · 9,670 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsP-Glycoprotein-Mediated Efflux and Drug Sequestration in Lysosomes Confer Advantages of K562 Multidrug Resistance Sublines to Survive Prolonged Exposure to Cytotoxic AgentsNathupakorn Dechsupa, Samlee MankhetkornProblem statement: Cellular drug resistance to anticancer agents is major obstacle in cancer chemotherapy and the mechanisms by which these MDR cells possess for protecting themselves to survive prolonged exposure to cytotoxic agents still debating. The study aimed to clarify the role of P-glycoprotein (Pgp) and enhanced drug sequestration in lysosomes to confer the multidrug resistance K562 cells with varied … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,504 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDiatrizoate, Iopromide and Iotrolan Enhanced Cytotoxicity of Daunorubicin in Multidrug Resistant K562/adr Cells: Impaired the Mitochondrial and Inhibited the P-Glycoprotein FunctionNitaya Snitwongse Na Ayudhya, Samlee MankhetkornMultidrug resistance was an obstacle in cancer chemotherapy because the cells decreased their intracellular drug accumulation by energy-dependent compounds efflux pumps such as P-glycoprotein (P-gp). This study observed some iodinated radiographic contrast media, diatrizoate, iopromide and iotrolan affected the cellular energetic state and the kinetics of P-gp in drug-sensitive K562 and drug resistant K562/adr cell lines using spectrophotometer and spectrofluorometer. … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,161 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDrug Susceptibility and Molecular Epidemiology of Pseudomonas aeruginosa Isolated in a Burn UnitHassan Salimi, Parviz Owlia, Bagher Yakhchali, Abdolaziz Rastegar LariProblem statement: Pseudomonas aeruginosa is an opportunistic pathogen that still develops life-threatening infections in patients with immunological system defects, like burn patients, especially in developing countries. Since this bacterium is naturally resistant to many drugs and is able to get resistance to all effective antibiotics, the infection with this organism is particularly problematic condition for patients. This study was design … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 6,992 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn Vitro Antimicrobial Activity of Modified Lysozyme (Lys 90) and Herbal Extracts Against Multidrug-Resistant Escherichia coliEni Kusumaningtyas, Bagem BR Sembiring, Andriani et al.The emergence of Antimicrobial Resistant (AMR) poses a significant challenge to the poultry farming industry. This study investigated the potential of Lysozyme (Lys), modified Lysozyme (Lys 90), an herbal extract, and their combination (herbs + Lys 90) as alternative antimicrobial agents against Multidrug-Resistant Escherichia coli (MDR-E. coli).
