3D‐Printed Scaffolds Promote Enhanced Spinal Organoid Formation for Use in Spinal Cord Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
3D‐printed organoid scaffolds with microscale channels are developed to enhance spinal cord injury recovery by guiding region‐specific spinal neural progenitor cells. These scaffolds promote axonal growth, cell maturation, and neuronal network formation.

An artifact in fits to conic-based surfaces [PDF]

open access: yes, 2009
It is common in Physiological Optics to fit the corneal and the lens surfaces to conic-based surfaces (usually ellipse-based surfaces), obtaining their characteristic radius of curvature and asphericity.

Covalent Binding of Dexamethasone to Polyimide Improves Biocompatibility of Neural Implantable Devices

open access: yesAdvanced Healthcare Materials, EarlyView.
The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.

Corneal re-innervation following refractive surgery treatments

open access: yesNeural Regeneration Research, 2019
Laser refractive surgery is one of the most performed surgical procedures in the world. Although regarded safe and efficient, it has side effects. All of the laser based refractive surgical procedures invoke corneal nerve injury to some degree.

Refractive Accuracy of a Novel Swept-Source OCT in Patients With Short and Long Eyes

open access: yesJournal of Ophthalmology
Conclusions: The novel SS-OCT biometer using individual refractive indices to measure AL showed an overall good refractive accuracy using the BUII. The results were similar or better with the optimized BTAL formula, suggesting that formulas purposely ...
