Changes in P2Y Purinergic Receptor Expression in the Ciliary Body in a Murine Model of Glaucoma

Frontiers in Pharmacology, 2017
Glaucoma is a neuropathology, often accompanied by an elevated intraocular pressure (IOP), which can lead to blindness. Since DBA/2J mice develop glaucoma, several studies of the physiopathology of glaucoma have been reported in this animal model.

Bifocal diffractive lenses based on the aperiodic Kolakoski sequence. [PDF]

Sci Rep
In this work, we present a new family of Zone Plates (ZPs) designed using the self-generating Kolakoski sequence. The focusing and imaging properties of these aperiodic diffractive lenses coined Kolakoski Zone Plates (KZPs) are extensively studied. It is

Optical Sensing Using Hybrid Multilayer Grating Metasurfaces with Customized Spectral Response. [PDF]

Sensors (Basel)
Customized metasurfaces allow for controlling optical responses in photonic and optoelectronic devices over a broad band. For sensing applications, the spectral response of an optical device can be narrowed to a few nanometers, which enhances its ...

Laser‐Assisted Micropatterned 3D Printed Scaffolds with Customizable Surface Topography and Porosity for Modulation of Cell Function

Advanced Healthcare Materials, Volume 14, Issue 3, January 27, 2025.
This study shows that integrating 3D printing with femtosecond laser engraving enables the precise formation of surface patterns on biomaterial scaffolds. The laser‐engraved micropatterns, such as microgrooves and micropits on poly(ε‐caprolactone) (PCL) scaffolds, retain their shape for at least 14 d in aqueous environments, significantly enhancing ...

Human eyes do not need monochromatic aberrations for dynamic accommodation

Ophthalmic and Physiological Optics, Volume 37, Issue 5, Page 602-609, September 2017., 2017
Abstract Purpose To determine if human accommodation uses the eye's own monochromatic aberrations to track dynamic accommodative stimuli. Methods Wavefront aberrations were measured while subjects monocularly viewed a monochromatic Maltese cross moving sinusoidally around 2D of accommodative demand with 1D amplitude at 0.2 Hz.

Propagation length enhancement of surface plasmon polaritons in gold nano‐/micro‐waveguides by the interference with photonic modes in the surrounding active dielectrics

Nanophotonics, Volume 6, Issue 5, Page 1109-1120, March 2017., 2017
Abstract In this work, the unique optical properties of surface plasmon polaritons (SPPs), i.e. subwavelength confinement or strong electric field concentration, are exploited to demonstrate the propagation of light signal at 600 nm along distances in the range from 17 to 150 μm for Au nanostripes 500 nm down to 100 nm wide (30 nm of height ...

Impact of stimulant treatment on refractive errors and pupil diameter in attention deficit hyperactivity disorder

Acta Ophthalmologica, Volume 102, Issue 5, Page e842-e850, August 2024.
Abstract Purpose The relationship between attention deficit hyperactivity disorder (ADHD) and visual impairment remains poorly understood, and the impact of visual impairment on the development of ADHD is uncertain. The aim of this study was to investigate the refractive profile and ocular biometric characteristics in patients diagnosed with ADHD and ...
