Chromatin remodeling enzyme Brg1 is required for mouse lens fiber cell terminal differentiation and its denucleation [PDF]
, 2010 Background: Brahma-related gene 1 (Brg1, also known as Smarca4 and Snf2 beta) encodes an adenosine-5'-triphosphate (ATP)-dependent catalytical subunit of the (switch/sucrose nonfermentable) (SWI/SNF) chromatin remodeling complexes.

Intraocular light scatter as modeled through a stratified medium [PDF]
, 2001 Intraocular light scatter is modeled through a stratified medium. It is shown that the eye lens possesses properties of an interference filter. In conditions that may mimic opacification, as found with cataract formation, such a filter may have stop ...

Dysfunctional lens syndrome: a prospective review
Revista Brasileira de Oftalmologia, 2021 The term dysfunctional lens syndrome has gained acceptance in the field and encompasses natural changes due to aging of crystalline lens. The evolution of diagnostic devices has been a key factor in better staging, understanding and characterizing of ...

A test for crystalline lens biocompatibility [PDF]
Eye, 1991 The current use of monkeys for testing intraocular fluids and viscoelastic materials is being questioned because of the decreasing availability and increasing cost of these scarce animals. The rabbit is an inexpensive, readily available, and convenient animal which might provide an alternative model for this purpose.

A Fully Customizable Anatomically Correct Model of the Crystalline Lens [PDF]
, 2011 The human eye is a complex optical system comprised of many components. The crystalline lens, an optical component with a gradient index (GRIN), is perhaps the least understood as it is situated inside the eye and as a result is difficult to characterize.

Mathematical models for describing the shape of the in vitro unstretched human crystalline lens [PDF]
, 2009 We developed orthogonal least-squares techniques for fitting crystalline lens shapes, and used the bootstrap method to determine uncertainties associated with the estimated vertex radii of curvature and asphericities of five different models.
