Principles of OCTA and Applications in Clinical Neurology [PDF]
Current Neurology and Neuroscience Reports, 2018 The article reviews the recent findings on the use of optical coherence tomography angiography (OCTA) in neurology.OCTA is a new addition to the powerful and complementary technology of the OCT. Due to its noninvasiveness, and reproducibility, it is possible to obtain high-resolution 3D images of the vessels of the human eye.

Biological and Pharmaceutical Bulletin, 2022 Octa-arginine (R8) has been extensively studied as a cell-penetrating peptide. R8 binds to diverse transmembrane heparan sulfate proteoglycans (HSPGs), including syndecans, and is internalized by cells. R8 is also reported to bind to integrin β1. In this study, we evaluated the biological activities of R8 and octa-lysine (K8), a peptide similar to R8 ...

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, 1999Nickel(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 ...

Journal of Thermal Analysis and Calorimetry, 2013
The mechanisms of the thermal degradation of polyhedral oligomeric octaphenylsilsesquioxane (OPS), octa(nitrophenyl)silsesquioxane (ONPS), and octa(aminophenyl)silsesquioxane (OAPS) were investigated. The –NO2 or –NH2 substituents on the phenyl group affected the mechanism of the POSS thermal degradation.
