Bromodomain and extra-terminal (BET) protein inhibitors have been reported as treatment options for acute myeloid leukemia (AML) in preclinical models are currently being evaluated clinical trials. This work presents a novel potent selective BET inhibitor (BI 894999), which has recently entered trials (NCT02516553). In studies, this compound is highly active AML cell lines, primary patient samples, xenografts. HEXIM1 described an excellent pharmacodynamic biomarker target engagement tumors...

To assess the antimicrobial susceptibility of Brucella melitensis strains in our region. Brucellosis is a common disease Turkey. Moreover, difficulties are encountered treatment process, such as long-lasting therapy, relapses, and side effects drugs. Hence, novel approaches current antibiotics vital. Materials methods: Thirty-four spp. isolated from blood samples patients with brucellosis were included. Minimal inhibitory concentrations for tetracycline, rifampicin, streptomycin,...

Bloodstream infection caused by extended-spectrum beta-lactamase (ESBL)-producing pathogens has become a serious concern worldwide. The purpose of this study was to identify risk factors for bacteremia due ESBL-producing Escherichia coli in Turkish hospital.We retrospectively reviewed the medical records patients with E. tertiary care centre from January 2007 October 2011. Data such as demographic features, underlying conditions, and antibiotic exposure were analysed.A total 113 included...

Transcription factors (TFs) are important mediators of aberrant transcriptional programs in cancer cells. In this study, we focus on TF activity (TFa) as a biomarker for cell-line-selective anti-proliferative effects, that high TFa predicts sensitivity to loss function given gene (i.e., genetic dependencies [GDs]). Our linear-regression-based framework identifies 3,047 pan-cancer and 3,952 cancer-type-specific candidate TFa-GD associations from cell line data, which then cross-examined...
