Noninvasive, In Vivo Assessment of Mouse Retinal Structure Using Optical Coherence Tomography [PDF]

, 2009
BACKGROUND: Optical coherence tomography (OCT) is a novel method of retinal in vivo imaging. In this study, we assessed the potential of OCT to yield histology-analogue sections in mouse models of retinal degeneration.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

The bright zone, a specialized dorsal eye region in the male blowfly Chrysomyia megacephala [PDF]

, 1989
In the compound eye of the male Chrysomyia megacephala the facets in the ventral part of the eye are only ca. 20 µm in diameter, but increase abruptly to ca. 80 µm above the equator of the eye.

Photomorphogenesis and Photoreceptors

, 2016
Plants use light as their main source of energy and to gather information about their surroundings. The light environment is monitored through an extensive set of photoreceptors and largely dictates plant development through induction of processes such as germination and flowering, entrainment of the circadian clock and photomorphogenic responses ...

Differentiation of Photoreceptors

, 2021
Chapter 7 discusses how photoreceptors and other cells found in the retina of the vertebrate eye or in the pineal body differentiate. These cell types do not develop from cranial placodes but from the neural tube. However, part three of the book will reveal that these cell types are evolutionarily closely related to other sensory cell types (e.g ...

Guanylate cyclase 1 relies on rhodopsin for intracellular stability and ciliary trafficking

eLife, 2015
Sensory cilia are populated by a select group of signaling proteins that detect environmental stimuli. How these molecules are delivered to the sensory cilium and whether they rely on one another for specific transport remains poorly understood. Here, we

Evolution of Photoreceptors

Cold Spring Harbor Symposia on Quantitative Biology, 1965
This essay will endeavor to demonstrate the relevance to photoreceptors of the Darwinian dictum: descent with modification. Considering the critical importance of radiant energy for almost all living organisms, it may be assumed that organelles adapted for activation by photons arose very early, perhaps not long after the evolution of the cell itself ...

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Oxidative Stress Induced Dysfunction of Protein Synthesis in 661W Mice Photoreceptor Cells

Proteomes, 2023
Photoreceptor cells are highly susceptible to oxidative-stress-induced damage due to their high metabolic rate. Oxidative stress plays a key role in driving pathological events in several different ocular diseases, which lead to retinal degeneration and ...
