Photobleaching and Fluorescence Recovery of RPE Bisretinoids. [PDF]

PLoS ONE, 2015
The autofluorescence of the retina that originates primarily from lipofuscin fluorophores in retinal pigment epithelial cells, is observed to undergo photobleaching during the acquisition of fundus autofluorescence images.

Near-infrared fundus autoflorescence imaging in solar retinopathy

GMS Ophthalmology Cases, 2017
Solar retinopathy is a rare clinical entity caused by photochemical damage to the retinal pigment epithelium layer and photoreceptors of the fovea. Here we describe a case of a 33-year-old female patient diagnosed by near-infrared fundus autofluorescence

Fundus Autofluorescence [PDF]

Güncel Retina Dergisi (Current Retina Journal), 2017
Fundus autofluorescence imaging has been shown to be useful with regard to the understanding of pathophysiologic mechanisms, diagnostics, phenotype-genotype correlation, identification of predictive markers for disease progression, and monitoring of novel therapies in retinal diseases.

Fundus autofluorescence and the bisretinoids of retina [PDF]

Photochemical & Photobiological Sciences, 2010
Imaging of the human fundus of the eye with excitation wavelengths in the visible spectrum reveals a natural autofluorescence, that in a healthy retina originates primarily from the bisretinoids that constitute the lipofuscin of retinal pigment epithelial (RPE) cells.

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.
