Cellular Changes in Retinas From Patients With BEST1 Mutations

Frontiers in Cell and Developmental Biology, 2020
Best disease (BD), also known as vitelliform macular dystrophy, is an inherited disease of the central retina caused by more than 300 pathogenic variants in the BEST1 gene.

Waveguide theory applied to optically measured angular sensitivities of fly photoreceptors [PDF]

, 1984
Farfield radiation patterns of single ommatidia of the fly, Calliphora erythrocephala, have been photographed. Clear radiation patterns of the first and the second waveguide mode have been observed. According to theory, the shape of the (optical) angular

Human Mesenchymal Stem Cell Secretome Exhibits a Neuroprotective Effect over In Vitro Retinal Photoreceptor Degeneration

Molecular Therapy: Methods & Clinical Development, 2020
Retinal photoreceptor degeneration occurs frequently in several neurodegenerative retinal diseases such as age-related macular degeneration, retinitis pigmentosa, or genetic retinal diseases related to the photoreceptors. Despite the impact on daily life

Physiological and Genetic Bases of the Circadian Clock in Plants and Their Relationship with Herbicides Efficacy [PDF]

Planta Daninha, 2016
In order to adapt to daily environmental changes, especially in relation to light availability, many organisms, such as plants, developed a vital mechanism that controls time-dependent biological events: the circadian clock.

Angular sensitivity of blowfly photoreceptors: intracellular measurements and wave-optical predictions [PDF]

, 1984
The angular sensitivity of blowfly photoreceptors was measured in detail at wavelengths λ = 355, 494 and 588 nm. The measured curves often showed numerous sidebands, indicating the importance of diffraction by the facet lens.

Retinal pigment epithelium extracellular vesicles are potent inducers of age‐related macular degeneration disease phenotype in the outer retina

Journal of Extracellular Vesicles, 2022
Age‐related macular degeneration (AMD) is a leading cause of blindness. Vision loss is caused by the retinal pigment epithelium (RPE) and photoreceptors atrophy and/or retinal and choroidal angiogenesis.

Developmental dynamics of cone photoreceptors in the eel [PDF]

, 2009
Background: Many fish alter their expressed visual pigments during development. The number of retinal opsins expressed and their type is normally related to the environment in which they live.

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.

An integrative model for phytochrome B mediated photomorphogenesis:from protein dynamics to physiology [PDF]

, 2010
Plants have evolved various sophisticated mechanisms to respond and adapt to changes of abiotic factors in their natural environment. Light is one of the most important abiotic environmental factors and it regulates plant growth and development ...
