Laser Photocoagulation for Retinal Detachments and Retinal Tears in Cytomegalovirus Retinitis

open access: yesOphthalmology, 1997
Retinal detachment complicates the course of cytomegalovirus (CMV) retinitis in nearly 30% of human immunodeficiency virus-infected patients. The study goal was to evaluate laser photocoagulation in the treatment of CMV retinitis-related retinal detachments and retinal tears.Nonrandomized, observational cohort study.Sixty-three patients with CMV ...

Retinal prostheses in degenerative retinal diseases

open access: yesJournal of the Chinese Medical Association, 2015
Degenerative retinal diseases may lead to significant loss of vision. Age-related macular degeneration (AMD) and retinitis pigmentosa (RP), which eventually affect the photoreceptors, are the two most common retinal degenerative diseases. Once the photoreceptorcells are lost, there are no known effective therapies for AMD or RP.

Retinal Vibrations in Bacteriorhodopsin are Mechanically Harmonic but Electrically Anharmonic: Evidence From Overtone and Combination Bands

open access: yesFrontiers in Molecular Biosciences, 2021
Fundamental vibrations of the chromophore in the membrane protein bacteriorhodopsin (BR), a protonated Schiff base retinal, have been studied for decades, both by resonance Raman and by infrared (IR) difference spectroscopy.

Molecular Properties of β-Carotene Oxygenases and Their Potential in Industrial Production of Vitamin A and Its Derivatives

open access: yesAntioxidants, 2022
β-Carotene 15,15′-oxygenase (BCO1) and β-carotene 9′,10′-oxygenase (BCO2) are potential producers of vitamin A derivatives, since they can catalyze the oxidative cleavage of dietary provitamin A carotenoids to retinoids and derivative such as ...
