LIBRARIES ARE AN ESSENTIAL COMPONENT of a nation’s information infrastructure, yet often they are invisible to their users and other stakeholders. In the context of this special issue, the paper presents four challenges faced by libraries and proposes research designs to address each of them. The four challenges involve: 1.invisible infrastructure, 2. content and collections, 3. preservation an...
VEGF-A and VEGF receptors, Flt-1/FLT-1 (VEGFR-1) and Flk-1/KDR (VEGFR-2), are key regulators of tumor angiogenesis and tumor growth. The purpose of this study was to determine the anti-angiogenic and anti-tumor efficacy of vascular-targeting fusion toxin VEGF121/rGel in an orthotopic glioblastoma mouse model using non-invasive in vivo bioluminescence imaging (BLI), magnetic resonance imaging (M...
Extracellular vesicles (EVs) can modulate microenvironments by transferring biomolecules including RNAs and proteins derived from releasing cells to target cells. To understand the molecular mechanisms maintaining the neural stem cell (NSC) niche through EVs, a new transgenic (Tg) rat strain that can release human CD63-GFP expressed EVs from the NSCs was established. Human CD63-GFP expression w...
