Perineuronal Nets (PNNs)

Perineuronal nets form during postnatal development, marking the end of what’s known as the “critical period” of heightened brain plasticity. PNNs are composed of extracellular matrix (ECM) molecules and are responsible for synaptic stabilization in the adult brain. PNNs are found around certain neuron cell bodies and proximal neurites in the central nervous system. Increasingly, researchers are turning to PNNs as potential targets to enhance plasticity for the treatment of various diseases. This illustration was created for the cover The Scientist magazine.

Bioabsorbable Stenting Technology

Bioabsorbable Stenting Technology

Metal stents can aggravate vessels and cause stent thrombosis that prevents vessel remodeling. They can also impair future surgical interventions and impede CT or MR imaging. Bioabsorbable stent technology is an alternative to traditional metal stents. In dissolving stents the entire scaffold is gradually absorbed by the body over time.
