INTRODUCTION The incidence of multidrug resistant microorganisms worldwide is increasing. The aim of the study was to present institutional experience with the multidrug resistant microorganism colonization patterns observed in children with congenital heart diseases hospitalized in a hybrid pediatric cardiac surgery center. MATERIAL AND METHODS Microbiological samples were routinely collecte...

Multidrug resistance is a potent barrier to effective, long term therapy in cancer patients. It is frequently attributed to enhanced expression of multidrug transporters or to the action of receptor kinases, such as ErbB2, and downstream anti-apoptotic signaling pathways, such as the phosphoinositide 3-kinase/Akt pathway. However, very few connections have been made between receptor kinases or ...

Considering the possibility to overcome drug resistance by other treatment strategies than chemotherapy we investigated the susceptibility of three independently selected multidrug-resistant sublines of the T-lymphoblastoid leukemic cell line CCRF-CEM to lymphokine-activated killer (LAK) cells. We found that two of the multidrug-resistant sublines were significantly less susceptible targets to ...

Doxorubicin plays an important role in the treatment of leukemias, lymphomas, and a variety of carcinomas. Tumor cell resistance to doxorubicin is often associated with expression of the multidrug resistance gene MDR1, which codes for the drug efflux pump P-glycoprotein, and a multidrug-resistant phenotype. Evidence from multiple sources suggests, however, that additional genes besides MDR1 are...

Failure of cancer chemotherapies is often linked to the over expression of ABC efflux transporters like the multidrug resistance P-glycoprotein (P-gp). P-gp expression in cells leads to the elimination of a variety of chemically unrelated, mostly cytotoxic compounds. Administration of chemotherapeutics during therapy frequently selects for cells that over express P-gp and are therefore capable ...

The multidrug transporter, initially identified as a multidrug efflux pump responsible for resistance of cultured cells to natural product cytotoxic drugs, is normally expressed on the apical membranes of excretory epithelial cells in the liver, kidney, and intestine. This localization suggests that the multidrug transporter may have a normal physiological role in transporting cytotoxic compoun...

BACKGROUND Multidrug-resistant tuberculosis (MDR-TB) is resistant to both rifampicin (RIF) and isoniazid (INH). Whereas many TB diagnostics detect RIF-resistance, few detect INH-monoresistance, which is common and may increase risk of acquired MDR-TB. Whether inclusion of INH-resistance in a first-line rapid test for TB would have an important impact on MDR-TB rates remains uncertain. METHODS...

Invasive infection of multidrug-resistant Streptococcus pneumoniae is a serious clinical concern. Here, we report the complete genome sequence of a multidrug-resistant S. pneumoniae serotype 19F strain isolated from a patient with an invasive infection in Sapporo, Japan.

Multidrug-resistant Klebsiella pneumoniae is a major cause of hospital-acquired infections. Here, we report the complete genome sequence of the multidrug-resistant, blaNDM-1-positive strain K. pneumoniae K66-45, isolated from a hospitalized Norwegian patient.

BACKGROUND Understanding the geographical distribution of multidrug-resistant tuberculosis (MDR-TB) in high TB burden countries such as Ethiopia is crucial for effective control of TB epidemics in these countries, and thus globally. We present the first spatial analysis of multidrug resistant tuberculosis, and its relationship to socio-economic, demographic and household factors in northwest Et...
