Background: Chronic myeloid leukemia is a clonal myeloproliferative disease which is characterized by bcr/abl translocation. With the emergence of tyrosine kinase inhibitors such as imatinib mesylate, significant improvement has been made in treatment of this disease. However, drug resistance against this medicine is still an obstacle. SIRT1 is a gene with deacetylase activity which has been de...

Introduction: Greatly increased use of antifungal therapies has resulted in the development of multidrug resistant. The phenolic compound carvacrol have been reported to have anti-Candida activity. This work is an attempt to examine effect of carvacrol on ergosterol synthesis against multidrug resistant Candida albicans. Methods: This cross-sectional study has been conducted on 30 immune-compr...

Drug-resistant tuberculosis is a public health concern. TB that drug-resistant to rifampin and isoniazid known as MDR-TB, whereas XDR-TB MDR-TB also resistant second-line medicines, such fluoroquinolones (levofloxacin, ofloxacin, moxifloxacin). rifampin-resistant (RR-TB), of which 78 percent had multidrug-resistant (MDR-TB) (MDR-TB). Fluoroquinolones are class broad-spectrum antimicrobials have...

Objective (s): In chemotherapy for cancer treatment, the cell resistance to multiple anticancer drugs is the major clinical problem. In the present study, mesoporous silica nanoparticles (MSNs) were used as a carrier for epirubicin (EPI) in order to improve the cytotoxic efficacy of this drug against the P-glycoprotein (P-gp) overexpressing cell line. Materials and Methods: MSNs with phosphonat...

the production of experimentally induced drug resistance in the laboratory provides valuable opportunities for investigators to study the nature and genetics of drug resistance mechanisms to a given agent, patterns of cross resistance and the mode of action of drugs. at the beginning the continuous drug exposure was chosen as a standard procedure to produce drug— resistant strains of p. falcipa...
