Glyconanofluorides as Immunotracers with a Tunable Core Composition for Sensitive Hotspot Magnetic Resonance Imaging of Inflammatory Activity.

ACS Nano 2021 Apr 19. Epub 2021 Apr 19.

Department of Organic Chemistry, Weizmann Institute of Science, Rehovot 7610001, Israel.

Nature-inspired nanosized formulations based on an imageable, small-sized inorganic core scaffold, on which biomolecules are assembled to form nanobiomimetics, hold great promise for both early diagnostics and developed therapeutics. Nevertheless, the fabrication of nanobiomimetics that allow noninvasive background-free mapping of pathological events with improved sensitivity, enhanced specificity, and multiplexed capabilities remains a major challenge. Here, we introduce paramagnetic glyconanofluorides as small-sized (<10 nm) glycomimetics for immunotargeting and sensitive noninvasive F magnetic resonance imaging (MRI) mapping of inflammation.

Combining biomarkers by maximizing the true positive rate for a fixed false positive rate.

Biom J 2021 Apr 19. Epub 2021 Apr 19.

Department of Biostatistics, University of Washington, Seattle, WA, USA.

Biomarkers abound in many areas of clinical research, and often investigators are interested in combining them for diagnosis, prognosis, or screening. In many applications, the true positive rate (TPR) for a biomarker combination at a prespecified, clinically acceptable false positive rate (FPR) is the most relevant measure of predictive capacity. We propose a distribution-free method for constructing biomarker combinations by maximizing the TPR while constraining the FPR. Read More
