One of the immunosurveillance mechanisms of the immune system is the expression of Major Histocompatibility Complex class I-related chain molecules A and B (MIC-A and B) on tumor cell surface. MIC-A and B are the ligands of an activating receptor, NKG2D expressed on the natural Killer cells (NK), therefore binding of NK cells to tumor cells through the interaction between NKG2D and MIC-A or MIC...

BACKGROUND Patients with methicillin-resistant Staphylococcus aureus (MRSA) infections caused by isolates with a high but 'susceptible' minimum inhibitory concentration (MIC) to vancomycin may suffer poor outcomes. The aim of this study was to determine the association of high compared to low vancomycin MICs and clinical outcomes (treatment failure and mortality) in patients with MRSA infection...

q8h for various half-lives from 1.5 to 7.3 h, based on data from [9] and [10]. The A/T ratio varies from 0.5 h/% to a little more than 2 h/% for the AUC/MIC range 25–225 h and is relatively independent of the half-life of the drug. Thus, the results clearly show that there is no justification for using the AUC/MIC ratio to predict the effect of a drug for which is the dynamically time 1 MIC lin...

In vivo studies have characterized the pharmacodynamic characteristics of the triazole fluconazole. These investigations demonstrated that the ratio of the area under the concentration-time curve from 0 to 24 h to the MIC (24-h AUC/MIC ratio) is the critical pharmacokinetic/pharmacodynamic (PK/PD) parameter associated with treatment efficacy. Further analysis demonstrated that a fluconazole 24-...

AN3365 (MIC(50/90), 0.5/1 μg/ml) was active against Enterobacteriaceae, including a subset of Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae strains (MIC(50/90), 1/2 μg/ml). AN3365 inhibited 98.0 and 92.2% of wild-type (MIC(50/90), 2/8 μg/ml) and carbapenem-resistant (MIC(50/90), 4/8 μg/ml) Pseudomonas aeruginosa strains, respectively, at ≤ 8 μg/ml. AN3365 also demonstrated a...

The MHC class I chain-related molecules (MICs) have previously been shown to be induced on most epithelial tumor cells. Engagement of MIC by the activating immune receptor NKG2D triggers NK cells and augments antigen-specific CTL anti-tumor immunity. The MIC-NKG2D system was proposed to participate in epithelial tumor immune surveillance. Paradoxically, studies suggest that tumors may evade MIC...

Echinocandins have become a first-line therapy for invasive candidiasis (IC). Using phase 3 trial data for patients with IC, pharmacokinetic-pharmacodynamic (PK-PD) relationships for efficacy for micafungin were examined. Micafungin exposures were estimated using a population pharmacokinetic model, and univariable and multivariable logistic regressions were used to identify factors associated w...

PURPOSE Current serum testing for the detection of prostate cancer (PCa) lacks specificity. On diagnosis, the optimal therapeutic pathway is not clear and tools for adequate risk assessment of localized PCa progression are not available. This leads to a significant number of men having unnecessary diagnostic biopsies and surgery. A search for novel tumor markers identified macrophage inhibitory...
