Functional and Genetic Analysis of Choroid Plexus Development in Zebrafish

Frontiers in Neuroscience, 2014
The choroid plexus, an epithelial-based structure localized in the brain ventricle, is the major component of the blood-cerebrospinal fluid barrier. The choroid plexus produces the cerebrospinal fluid and regulates the components of the cerebrospinal ...

Automated segmentation of choroidal layers from 3-dimensional macular optical coherence tomography scans [PDF]

arXiv, 2021
Background: Changes in choroidal thickness are associated with various ocular diseases and the choroid can be imaged using spectral-domain optical coherence tomography (SDOCT) and enhanced depth imaging OCT (EDIOCT). New Method: Eighty macular SDOCT volumes from 80 patients were obtained using the Zeiss Cirrus machine.

Findings of 18F‐PI‐2620 tau PET imaging in patients with Alzheimer’s disease and healthy controls in relation to the plasma P‐tau181 levels in a Japanese sample

Neuropsychopharmacology Reports, Volume 42, Issue 4, Page 437-448, December 2022., 2022
The present pilot study examined the ability of 18F‐PI‐2620 tau PET tracer to distinguish between healthy control and Alzheimer's disease, as well as correlations with plasma p‐tau181 and cognitive test results. Though the sample size was small, seven for each group, its SUVR in the target brain regions showed distinct differences between them and high

Analysis of retinal and choroidal images measured by laser Doppler holography [PDF]

, 2019
Laser Doppler holography (LDH) is a full-field imaging technique that was recently used in the human eye to reveal blood flow contrasts in the retinal and choroidal vasculature non-invasively, and with high temporal resolution. We here demonstrate that the ability of LDH to perform quantitative flow measurements with high temporal resolution enables ...

Fetal cerebral ventriculomegaly: What do we tell the prospective parents?

Prenatal Diagnosis, Volume 42, Issue 13, Page 1674-1681, December 2022., 2022
Abstract Fetal cerebral ventriculomegaly is a relatively common finding, observed during approximately 1% of obstetric ultrasounds. In the second and third trimester, mild (≥10 mm) and severe ventriculomegaly (≥15 mm) are defined according to the measurement of distal lateral ventricles that is included in the routine sonographic examination of central
