The MEV probe (yellow), which is designed to curve into branched (vs. straight) blood vessels, is selectively injected into the branched vessel by saline flow through the microcatheter (cyan) in which it was...
Megan Brooks July 21, 2023 Treatment with an experimental oral tau aggregation inhibitor, hydromethylthionine mesylate (HMTM), led to a statistically significant reduction in an established biomarker of neurodegeneration in Alzheimer’s disease (AD) in the LUCIDITY phase 3 trial. Blood concentrations of neurofilament light chain (NfL) showed a 93% reduction in change over 12 months in participants receiving...
