Surgeons use patients' own stem cells to rebuild damaged corneas

Surgeons at Massachusetts Eye and Ear have replaced the ocular surface of four patients who each experienced chemical burns to one eye by using their own stem cells taken from the other healthy eye, in a technique known as "cultivated autologous limbal epithelial cell transplantation" (CALEC).

Brain estrogen critical for astrocyte activation and neuroprotection

When the brain isn't getting enough oxygen, estrogen produced by neurons in both males and females hyperactivates another brain cell type called astrocytes to step up their usual support and protect brain function.

Silicon nitride shows potent SARS-CoV-2 neutralization capability

A new study published on the preprint server bioRxiv* in August 2020 shows that the man-made compound silicon nitride, which is used in medical implants and high mechanical performance engineering applications, is capable of inactivating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at varying concentrations without causing cell cytotoxicity. This finding should be investigated to develop disinfectants to clear the virus from surfaces, preventing its spread.
