Misdiagnosis or missed diagnosis: Occult lens subluxation in eyes presenting with acute angle closure glaucoma

Indian Journal of Ophthalmology. Case Reports
Anterior subluxation of the crystalline lens can precipitate acute secondary angle closure with a rapid rise in intraocular pressure mimicking an attack of acute primary angle closure glaucoma.

Spontaneous Nanopatterning and Strain Relaxation in SiGe Layers Grown by Oxidative Solid‐Phase Epitaxy

Advanced Materials Interfaces, EarlyView.
Thin SiGe buffer layers are grown by oxidative solid‐phase epitaxy, resulting in a nanopatterning of varying Ge concentration across the surface of the sample. The nanopatterning is caused by a hexagonal network of dislocations on the SiGe/Si(111) interface, and is visible by scanning electron microscopy, providing a non‐destructive method for ...

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.

Culinary Chemistry as a Platform for Interfacial Materials Design

Advanced Materials Interfaces, EarlyView.
Culinary processes control interfaces through heating, shear, gelation, and molecular transport. This Review connects selected gastronomic examples with food‐derived nanomaterials, plasmonic sensing, anthocyanin photovoltaics, and intelligent packaging. Original agar‐based plasmonic films illustrate the proposed translation.

The Influence of extracellular matrix on lens epithelial cell viability [PDF]

, 2006
Posterior capsular opacification is the main complication of cataract surgery and results from the proliferation, migration and differentiation of lens epithelial cells remaining in the capsular bag. To better understand this pathological cell behaviour,
