Clinical Features of a Pediatric Case with Cone Dystrophy

Van Tıp Dergisi, 2018
The cone dystrophy is a nonhomogenous group of inherited and progressive retinal diseases that affects chiefly the cone system. It is frequently characterized by progressive loss of visual acuity, photophobia, central scotoma, color vision disturbances ...

Visual function and cortical organization in carriers of blue cone monochromacy. [PDF]

PLoS ONE, 2013
Carriers of blue cone monochromacy have fewer cone photoreceptors than normal. Here we examine how this disruption at the level of the retina affects visual function and cortical organization in these individuals.

Attentional Blink Effects on S-Cone Stimuli

i-Perception, 2019
This study aimed to compare attentional blink (AB) effects on S-cone and on luminance stimuli. Recent research had revealed considerable AB effects not only on high-order visual areas but also on low-order visual areas.

Dysflective cones: Visual function and cone reflectivity in long-term follow-up of acute bilateral foveolitis

American Journal of Ophthalmology Case Reports, 2017
Purpose: Confocal adaptive optics scanning laser ophthalmoscope (AOSLO) images provide a sensitive measure of cone structure. However, the relationship between structural findings of diminished cone reflectivity and visual function is unclear.

Asymmetries around the visual field: From retina to cortex to behavior.

PLoS Computational Biology, 2022
Visual performance varies around the visual field. It is best near the fovea compared to the periphery, and at iso-eccentric locations it is best on the horizontal, intermediate on the lower, and poorest on the upper meridian.

Theoretical and experimental studies of a novel cone-jet sensor [PDF]

, 2001
Modeling of a novel cone-jet sensor using two-dimensional (2-D) finite element analysis was investigated for dimensional measurement. Theoretical and experimental studies demonstrated that a cone-jet sensor supplied with air can be used to accurately ...

Novel rodent models for macular research [PDF]

, 2010
BACKGROUND: Many disabling human retinal disorders involve the central retina, particularly the macula. However, the commonly used rodent models in research, mouse and rat, do not possess a macula.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Euler-Savary's Formula for the Planar Curves in Two Dimensional Lightlike Cone [PDF]

, 2010
In this paper, we study the Euler-Savary's formula for the planar curves in the lightlike cone. We first define the associated curve of a curve in the two dimensional lightlike cone Q2:Then we give the relation between the curvatures of a base curve, a ...
