The effect of polar lipids on tear film dynamics [PDF]

, 2009
In this paper we present a mathematical model describing the effect of polar lipids on the evolution of a precorneal tear film, with the aim of explaining the interesting experimentally observed phenomenon that the tear film continues to move upwards ...

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

Advanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

Study of factors influencing central corneal thickness among patients attending ophthalmology outpatient department at a tertiary care center in North Kerala

Kerala Journal of Ophthalmology, 2016
Context: Central corneal thickness (CCT) was assumed to be a constant when Goldmann designed his applanation tonometer. Knowledge of the CCT is of importance in the assessment of intraocular pressures (IOPs).

Evaluating Cytocompatibility of Corynebacterium glutamicum‐poly Vinyl Alcohol Living Biomaterials for Ocular Use

Advanced Healthcare Materials, EarlyView.
In ophthalmology, living biomaterials such as living contact lenses appear promising for sustained drug delivery or biosensing. The cytocompatibility of Cg‐PVA hydrogels, developed as a model living contact lens, is investigated with the ocular surface, showing their potential translation to the clinic.

Giving It a Twist: One‐Step Fabrication of Aligned Biomimetic Yarn Scaffolds via Rotational Melt Electrofibrillation

Advanced Healthcare Materials, EarlyView.
Due to its multifunctionality, replicating the fibrillar and supramolecular architecture of Collagen I is gaining increasing priority in regenerative medicine. Using rotational Melt Electrofibrillation, we present a powerful method to accurately mimic the ultrastructure of Collagen with polycaprolactone, enabling the one‐step fabrication of three ...
