Nanomedicine modification with ligands directed to receptors on tumor blood vessels has the potential for selectively enhancing nanomedicine accumulation in malignant tissues by overcoming the vascular barrier of tumors. Nevertheless, the development of broadly applicable ligand approaches capable of promoting

Nanoparticles made of metal-organic frameworks (nanoMOFs) are becoming of increasing interest as drug carriers. However, engineered coatings such as poly(ethylene glycol) (PEG) based ones are required to prevent nanoMOFs recognition and clearance by the innate immune system, a prerequisite for

The synthesis and self-assembly of peptide-polymer conjugates into fibrillar nanostructures are reported, based on the amyloidogenic peptide KLVFF. A strategy for rational synthesis of polymer-peptide conjugates is documented via tethering of the amyloidogenic peptide segment LVFF (Aβ17-20 ) and its

Excitatory postsynaptic currents (EPSCs), miniature excitatory postsynaptic currents (MEPSCs), and acetylcholine-induced current fluctuations (noise) have been studied in voltage-clamped bullfrog parasympathetic ganglion cells of the atrial septum. EPSCs were also recorded from voltage-clamped sympathetic B cells and, in general, it

The development of miniature end-plate currents (m.e.p.c.s) was studied in the superior oblique and interhyoideus muscles of Xenopus laevis. An analysis of m.e.p.c. decays shows that each muscle possesses its own characteristic programme of end-plate current development. In the superior
