OCTA-ReVA: Comprehensive open-source tool for retinal vessel analysis in OCTA

Abstract: Optical Coherence Tomography Angiography (OCTA) has significantly advanced the study and diagnosis of eye diseases by offering non-invasive, detailed 3D imagery of retinal blood vessels. Yet, the quantitative analysis capabilities of existing clinical OCTA systems remain limited.

Novel octa-graphene-like structures based on GaP and GaAs

Journal of Molecular Modeling, 2023
Context: The discovery of graphene gave way to the search for new two-dimensional structures. In this regard, octa-graphene is a carbon allotrope consisting of 4- and 8-membered rings in a single planar sheet, drawing the research community’s attention ...

OCTA in Glaucoma

2020
Optical coherence tomography angiography (OCTA) is a noninvasive, fast, and cost-effective modality that provides high-resolution 3D imaging of the retinal microvasculature. OCTA uses the variation in optical coherence tomography (OCT) signal caused by moving particles—namely, red blood cells—as the contrast agent for imaging blood flow.

Syntheses of Octa(dialkylamino)azaphthalocyanines

Journal of Porphyrins and Phthalocyanines, 1999
Nickel(II) octa(4-morpholinyl)- (11a) and copper(II) octa(1-pyrrolidinyl)- (11b) azaphthalocyanines have been prepared from the corresponding pyrazine diiminoimides (10). The precursor pyrazine dicarbonitriles (2) gave 6-cyanopyrazine-5-alkyl carboximidates (3-9) as stable intermediates when reacted with ammonia and catalytic amounts of sodium ...
