Choroidal Sclerosis and Choroidal Atrophy

Güncel Retina Dergisi (Current Retina Journal), 2022
In the case of choroidal degenerative diseases that may result in choroidal sclerosis, the basic pathology begins in the retinal pigment epithelium. After the loss of retinal pigment epithelium, the choriocapillaris layer is affected and atrophies develop. In the advanced stages of the disease, large choroidal vessels present a sclerotic appearance due

Fuchs’ Adenoma of the Choroid Simulating a Choroidal Hemangioma [PDF]

Case Reports in Ophthalmology, 2012
We report the case of a 54-year-old female who was referred to us with an amelanotic mass on the posterior pole of the left eye involving the macula. Fundus fluorescein angiography revealed a hyperfluorescent choroidal mass. Indocyanine green chorioangiography revealed a hypofluorescent choroidal lesion with hyperfluorescent margins.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.
