Short-term natural history of macular neovascularization in nonexudative age-related macular degeneration using multimodal imaging

Scientific Reports
The short-term conversion rate of a non-exudative macular neovascularization (ne-MNV) to an exudative stage in age-related macular degeneration (AMD) was evaluated in a single-center, retrospective case control study and associated imaging ...

Ultrafast Backbone Protonation in Channelrhodopsin-1 Captured by Polarization Resolved Fs Vis-pump—IR-Probe Spectroscopy and Computational Methods

Molecules, 2020
Channelrhodopsins (ChR) are light-gated ion-channels heavily used in optogenetics. Upon light excitation an ultrafast all-trans to 13-cis isomerization of the retinal chromophore takes place.

Reversible Photochromic Reactions of Bacteriorhodopsin from Halobacterium salinarum at Femto- and Picosecond Times

Molecules
The operation of bacteriorhodopsin (BR) from the archaeon Halobacterium salinarum is based on the photochromic reaction of isomerization of the chromophore group (the retinal protonated Schiff base, RPSB) from the all-trans to the 13-cis form.

Molecular mechanisms separating two axonal pathways during embryonic development of the avian optic tectum [PDF]

, 1991
During embryonic development of the avian optic tectum, retinal and tectobulbar axons form an orthogonal array of nerve processes. Growing axons of both tracts are transiently very closely apposed to each other. Despite this spatial proximity, axons from
