Although histone deacetylase (HDAC) inhibitors are emerging as a promising class of cancer chemotherapeutic agents, their effects on multidrug resistance (MDR) are poorly understood. In this study, we investigated whether HDAC inhibitors overcome MDR phenotype. HDAC inhibitors suppress the growth of both MDR positive cancer cells KBV20C and its parental cells KB with similar potencies. In paral...

Multidrug-resistant strain of Mycobacterium tuberculosis (MDR-Tb) and Multidrug-sensitive Mycobacterium tuberculosis (MDS-Tb) isolated from humans were injected subcutaneously into the guinea pigs. One set of infected lungs of animals was fixed in 10% formalin pH7.2, while the other set was treated with 75% ethanol 2 hours prior to fixation in 10% formalin. After six months of fixation, MDS-Tb ...

Background Multidrug resistance (MDR) TB is on the rise globally and is associated with significant morbidity and mortality. Conventional culture based drug susceptibility testing (DST) for TB drugs is time consuming, leading to diagnostic delays contributing to higher TB morbidity and mortality and exacerbation of ongoing transmission. Moreover most of the NTM(Non tuberculous mycobacteria) tha...

OBJECTIVE Previous tuberculosis (TB) treatment status is an established risk factor for multidrug-resistant TB (MDR-TB). This study explores which factors related to previous TB treatment may lead to the development of multidrug resistant in Bangladesh. DESIGN We previously conducted a large case-control study to identify risk factors for developing MDR-TB in Bangladesh. Patients who had a hi...

The aim of the present study was to investigate the reversal effect and its related mechanism of Ginkgo biloba exocarp extracts (GBEEs) in obtained multidrug resistance (MDR) of mice S180 tumor cells in vitro and in vivo. In order to simulate the clinical PFC [cis-dichlorodiamineplatinum, cisplatin (DDP) + fluorouracil (FU), FU+cyclophosphamide and cyclophosphamide] scheme, a gradually increasi...

To overcome multidrug resistance (MDR) in cancer chemotherapy, we prepared various plant extracts and searched for a component which is effective for inhibition of MDR. MDR inhibition activity was determined by measuring cytotoxicity to MDR cells using multidrug resistant human fibrocarcinoma KB V20C, which is resistant to 20 nM vincristine and expresses high level of mdr1 gene. Of various plan...

ABSTRACT Objective: Analyze risk factors for infection in kidney transplant recipients from deceased expanded criteria donors (DECD) the first two years of follow-up. Method: This is a prospective cohort study with 466 patients DECD who underwent transplantation 2015 and 2016 Brazil. A total 551 events were recorded. The largest incidence infectious occurred month after transplantation. Cytomeg...

The rise of multidrug-resistant tuberculosis (MDR-TB), defined as tuberculosis showing resistance to at least isoniazid and rifampicin, is a serious threat to tuberculosis control in some high prevalence countries and may have some impact on low prevalence regions as well. The World Health Organization estimates that 50 million people worldwide are infected with MDR-TB, and that, in the year 20...

A cryptic multidrug resistance (MDR) system in Stenotrophomonas maltophilia, the expression of which is selectable by tetracycline, is described. Tetracycline resistance was the consequence of active efflux of the antibiotic, and it was associated with resistance to quinolones and chloramphenicol, but not to aminoglycosides or beta-lactam antibiotics. MDR is linked to the expression of an outer...
