Choroidal melanoma

Oman Journal of Ophthalmology, 2012
Choroidal melanoma is the most common primary intra-ocular malignant tumor and second most common site of ten malignant melanoma sites in the body. Current diagnosis of choroidal melanoma is based on both the clinical experience of the specialist and modern diagnostic techniques such as indirect ophthalmoscopy, A- and B-ultrasonography scans, fundus ...

NETs‐CD44‐IL‐17A Feedback Loop Drives Th17‐Mediated Inflammation in Behçet's Uveitis

Advanced Science, EarlyView.
In experimental autoimmune uveitis (EAU), neutrophils interact with T helper 17 (Th17) cells through neutrophil extracellular traps (NETs) to exert a pro‐inflammatory effect. In vitro and in vivo experiments identify that NETs promote IL‐17A secretion in Th17 cells via CD44, and increasing IL‐17A further induces more NETs formation.

Targeting choroid plexus epithelium as a novel therapeutic strategy for hydrocephalus

Journal of Neuroinflammation, 2022
The choroid plexus is a tissue located in the lateral ventricles of the brain and is composed mainly of choroid plexus epithelium cells. The main function is currently thought to be the secretion of cerebrospinal fluid and the regulation of its pH, and ...

Choroidalyzer: An open-source, end-to-end pipeline for choroidal analysis in optical coherence tomography [PDF]

arXiv, 2023
Purpose: To develop Choroidalyzer, an open-source, end-to-end pipeline for segmenting the choroid region, vessels, and fovea, and deriving choroidal thickness, area, and vascular index. Methods: We used 5,600 OCT B-scans (233 subjects, 6 systemic disease cohorts, 3 device types, 2 manufacturers).

The Cerebrospinal Fluid Secretion Rate Increases in Awake and Freely Moving Rats but Differs With Experimental Methodology

Advanced Science, EarlyView.
CSF dynamics are vital for neurological health. Yet accurate quantification of CSF rates is challenging. Using a novel technique in awake, freely moving rats, significantly higher secretion rates are found than in anesthetized rats. The findings highlight the importance of awake models and the adaptability of methods for studying CSF changes influenced

Verteporfin‐Mediated In Situ Nanovaccine Based on Local Conventional‐Dose Hypofractionated Radiotherapy Enhances Antitumor and Immunomodulatory Effect

Advanced Science, EarlyView.
Here gelatinase‐responsive methoxypolyethyleneglycol–PVGLIG–polycaprolactone (mPEG–PVGLIG–PCL) nanoparticles’ loading verteporfin (N@VP) is developed, enhancing radiotherapy via X‐ray‐triggered singlet oxygen generation. Combined with 2 Gy (gray, a radiation dose unit) irradiation, N@VP achieves antitumor efficacy comparable to 8 Gy, and also promotes ...

Gold nanoparticles-based brachytherapy enhancement in choroidal melanoma using a full Monte Carlo modelling of human eye [PDF]

J Appl Clin Med Phys. 2015 Sep 8;16(5):5568, 2014
The effects of gold nanoparticles in 125I brachytherapy dose enhancement on choroidal Melanoma are examined using the Monte Carlo simulation technique. Usually, Monte Carlo ophthalmic brachytherapy dosimetry is performed in a water phantom. However, here, the compositions of human eye have been considered instead of water.

A case of choroidal melanocytoma mimicking a choroidal melanoma

Saudi Journal of Ophthalmology, 2015
A 17-year-old young girl was seen by us with complaints of progressive, painless decreasing vision in one eye for the last 4 years. No other supporting history could be elucidated. On examination, a large choroidal mass was found. Since the features were suggestive of malignant melanoma of the choroid, an enucleation of the eye was performed ...
