Mesoporous silica-coated hollow manganese oxide (HMnO@mSiO(2)) nanoparticles were developed as a novel T(1) magnetic resonance imaging (MRI) contrast agent. We hypothesized that the mesoporous structure of nanoparticle shell enables optimal access water molecules to core, and consequently, an effective longitudinal (R(1)) relaxation enhancement protons, which value was measured be 0.99 (mM(-1)s(-1)) at 11.7 T. Adipose-derived mesenchymal stem cells (MSCs) efficiently labeled using...
Soluble β-amyloid (Aβ) oligomers impair synaptic plasticity and cause loss associated with Alzheimer's disease (AD). We report that murine PirB (paired immunoglobulin-like receptor B) its human ortholog LilrB2 (leukocyte B2), present in brain, are receptors for Aβ oligomers, nanomolar affinity. The first two extracellular immunoglobulin (Ig) domains of mediate this interaction, leading to enhanced cofilin signaling, also seen AD brains. In mice, the deleterious effect on hippocampal...
The two oxidation states of ceria nanoparticles, Ce3+ and Ce4+, play a pivotal role in scavenging reactive oxygen species (ROS). In particular, is largely responsible for removing O2− .OH that are associated with inflammatory response cell death. synthesis reported 2 nm ceria–zirconia nanoparticles (CZ NPs) possess higher Ce3+/Ce4+ ratio faster conversion from Ce4+ to than those exhibited by nanoparticles. obtained Ce0.7Zr0.3O2 (7CZ) NPs greatly improve ROS performance, thus regulating cells...
Ag+ ions are a well-known antibacterial agent, and Ag nanoparticles act as reservoir of these for targeted therapy bacterial infections. However, there no tools to effectively trigger monitor the release from nanoparticles. Photoacoustic (PA) imaging is an emerging noninvasive tool, gold nanorods (AuNRs) excellent contrast agent PA imaging. In this work, we developed Au/Ag hybrid by coating AuNRs with silver (Ag), which decreased their photoacoustic signal. The as-prepared, Ag-coated Au...
Implantable endovascular devices such as bare metal, drug eluting, and bioresorbable stents have transformed interventional care by providing continuous structural mechanical support to many peripheral, neural, coronary arteries affected blockage. Although effective in achieving immediate restoration of blood flow, the long-term re-endothelialization inflammation induced are difficult diagnose or treat. Here we present nanomaterial designs integration strategies for electronic stent with...
The growth of one metal-organic framework (MOF) on another MOF for constructing a heterocompositional hybrid is an interesting research topic because the curiosity regarding occurrence this phenomenon and value MOFs as multifunctional materials or routes fine-tuning properties.
