The overexpression of the breast cancer resistance protein (ABCG2) confers resistance to Adriamycin (ADR) in breast cancer. The silencing of ABCG2 using small interfering RNA (siRNA) could be a promising approach to overcome multidrug resistance (MDR) in cancer cells. To deliver ABCG2-siRNA effectively into breast cancer cells, we used mPEG-PLGA-PLL (PEAL) nanoparticles (NPs) with ultrasound-ta...

Adriamycin (ADR) is a potent anticancer drug used to treat a variety of cancers. Patients treated with ADR have experienced side effects such as heart failure, cardiomyopathy, and "chemobrain", which have been correlated to changes in protein expression in the heart and brain. In order to better understand cellular responses that are disrupted following ADR treatment in immune tissues, this wor...

Multidrug resistance (MDR) is a major impediment to successful cancer chemotherapy. Co-delivery of novel MDR-reversing agents and anticancer drugs to cancer cells holds great promise for cancer treatment. MicroRNA-21 (miR-21) overexpression is associated with the development and progression of MDR in breast cancer, and it is emerging as a novel and promising MDR-reversing target. In this study,...

An MCF-7 human breast cancer cell line was selected which was 200fold more resistant to Adriamycin than the wild type cell line. This Adriamycin-resistant (Adr") cell line exhibited a multidrug-resistant phenotype and was cross-resistant to a wide range of antineoplastic agents including Vinca alkaloids, anthracyclines, and epipodophyllotoxins. Cytogenetic analysis of the Adr" cell line showed ...

A new technique for low-cost error correction in computers is the alternate-data retry (ADR). An ADR is initiated by the detec,* * . tion of an error in the initial execution of an operation. The ADR is a re-execution of the operation, but with an alternate representation of the initial data. The choice of the alternate representation and the design of the processing circuits combine to insure ...

The localization of glycine (GR) and adrenergic receptors (AdR) was examined in the rat brain using a monoclonal antibody against the affinity purified glycine receptor and a polyclonal antibody against purified beta2-AdR. GR were concentrated in the lower brainstem, whereas no immunoreactivity was observed in the diencephalon and forebrain except in a few diencephalic nuclei. The highest densi...

Considerable evidence supports a role for brainstem adrenergic and noradrenergic inputs to corticotropin-releasing hormone (CRH) cells of the hypothalamic paraventricular nucleus (PVN), in the control of hypothalamic-pituitary-adrenocortical (HPA) axis function. However, little is known about specific adrenoceptor (ADR) subtypes in CRH-containing cells of the PVN. Here we demonstrate, using dua...

BACKGROUND We sought to evaluate the difference between hospital service costs of 2 treatment options for patients diagnosed with 3-level degenerative disc disease (DDD) in the lumbar spine. In this retrospective analysis, itemized billing records of hospital stay for patients with 3-level DDD treated with artificial disc replacement (ADR) were compared with those treated with circumferential f...

The purpose of these studies was to determine the effect of Adriamycin (ADR) on the ability of liposome-encapsulated immunomodulators to activate human blood monocytes to the tumoricidal state. We undertook these experiments because we envisioned using encapsulated activators in addition to chemotherapy to destroy pulmonary micrometastases in patients with osteosarcoma (OS). Prior to the initia...

background: the reporting of adverse drug reactions (adrs) by nurses in hospitals is very important.aims: this study was aimed at investigating the impact of an educational intervention to improve adr reporting and whethertrained nurses had better knowledge, attitude, and practice toward adr reporting. materials and methods: a total of 300 nurses in a tertiary care teaching hospital in tehran, ...
