Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues

Advanced Science, EarlyView.
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

In Situ Photo‑Crosslinked Functional Bilayer Hydrogel Modulates Local Microenvironment and Remyelination After Optic Nerve Injury

Advanced Science, EarlyView.
A blue‐light‐crosslinked bilayer hydrogel was developed for local optic nerve repair. The adhesive GM‐Odex outer layer seals and anchors the lesion, while the non‐adhesive GM‐imid inner layer releases MPDA‐Cle without obstructing CSF flow. This system modulates oxidative and inflammatory microenvironments, supports oligodendrocyte differentiation and ...

1,2‐propanediol reformulation improves tribromoethanol safety and reveals pontine GABRA1 enrichment as a candidate mechanistic correlate of anesthesia

Animal Models and Experimental Medicine, EarlyView.
This study develops a reformulated tribromoethanol (TBE) anesthetic using 1,2‐propanediol as a solvent to overcome solvent‐related toxicity. The novel formulation demonstrates, cardiovascular stability, and survival in prolonged protocols. It provides potent, dose‐dependent anesthesia without strain or sex differences.

Corneal curvature in young high myopic undergraduates in southern Nigeria [PDF]

, 2018
Background: Corneal curvature is important for contact lens fitting and management, ocular aberration analysis, corneal refractive surgery as well as diagnoses and management of corneal pathological conditions such as keratoconus and it is also an ...

Innovative PLA or PCL‐Based Ocular Implants Obtained From Tape Casting or Electrospinning for Sustained‐Release Dexamethasone

Journal of Applied Polymer Science, EarlyView.
PLA and PCL ocular implants prepared by tape casting and electrospinning provide sustained dexamethasone release with distinct release profiles governed by polymer type and processing method. The relationship between polymer structure, degradation behavior, and drug release demonstrates the potential of these fabrication techniques for controlled ...

Analyzing contact lens induced changes of the corneal curvature [PDF]

, 1970
Contact lens wear generally induces changes of corneal curvature as measured with the keratometer. Previous studies have considered only one dimension of the curvature change or the fir of the lens.

Marine‐Derived Type I Collagen From Scyliorhinus canicula: Extraction, Characterization, and Biomedical Applications

Journal of Applied Polymer Science, EarlyView.
Marine‐derived type I collagen is extracted from Scyliorhinus canicula skin and characterized by physicochemical and morphological analyses. The collagen exhibits excellent biocompatibility, promotes wound healing, reduces inflammatory mediators, and inhibits melanogenesis.
