Structural corneal changes identified with the use of confocal microscopy after accelerated CXL for keratoconus

Journal of Ophthalmology, 2020
Background: Post-crosslinking (CXL) biomicroscopic changes in patients with keratoconus can be detected by confocal microscopy. Few studies reported on morphological changes in the cornea after CXL.

Dynamic, Reconfigurable, and Hierarchical Biosynthetic Composites via Collagen Self‐Assembly within Highly Crowded Microgel Pastes

Advanced Materials, EarlyView.
A new approach to extracellular matrix‐mimetic, hierarchical biomaterials is presented. Soft gels composed of overpacked hydrogel microparticle arrays present a biomolecularly crowded environment permissive to the self‐assembly of collagen networks.

Optimization of Optical and Mechanical Properties of Real Architecture for 3-Dimensional Tissue Equivalents: Towards Treatment of Limbal Epithelial Stem Cell Deficiency [PDF]

, 2015
Limbal epithelial stem cell (LESC) deficiency can cause blindness. Transplantation of cultured human limbal epithelial cells (hLE) on human amniotic membrane (HAM) can restore vision but clinical graft manufacture can be unreliable.

Microwave treatment of the cornea leads to localised disruption of the extracellular matrix [PDF]

, 2018
Microwave keratoplasty is a thermo-refractive surgical procedure that can correct myopia (short-sightedness) and pathologic corneal steepening by using microwave energy to cause localised shrinkage around an annulus of the cornea leading to its ...

Biodegradable Carbonate Nanogels Loaded with Anti MFAP‐5 siRNA for Anti‐stromal Therapy of Hepatocellular Carcinoma

Advanced Science, EarlyView.
Polycarbonate nanogels enable lipid‐free delivery of anti‐MFAP‐5 siRNA into cancer‐associated fibroblasts (CAF) in hepatocellular carcinoma. In a cirrhotic murine model, this approach silences MFAP‐5, reduces fibroblast activation, and suppresses tumor growth by inhibiting NOTCH/Hes1‐driven angiogenesis. CAF‐targeted MFAP‐5 RNAi and conserved signaling
