Reflections on the Utility of the Retina as a Biomarker for Alzheimer's Disease: A Literature Review. [PDF]

, 2019
As a part of the central nervous system, the retina may reflect both physiologic processes and abnormalities related to diseases of the brain. Indeed, a concerted effort has been put forth to understand how Alzheimer's disease (AD) pathology may manifest

Synthesis and characterizations of peripheral octa-amino and octa-amidophthalocyanines

Journal of Porphyrins and Phthalocyanines, 2008
Novel 2,3,9,10,16,17,23,24-octaamino substituted Ni(II) phthalocyanine (2) was synthesized from tosylamido (tosyl: toluene-p-sulphonyl) derivative by the cleavage of tosyl groups in the presence of 90% sulfuric acid. Octa-hexanoylamido Ni(II) phthalocyanine (3a) and octa-lauroylamido Ni(II) phthalocyanine (3b) were obtained by reacting of octa-amino ...

Clinical utility of OCTA

Canadian Eye Care Today, 2022
Optical coherence tomography angiography (OCTA) is a novel technology that can produce images of blood flow with unprecedented resolution of all the vascular layers of the retina and choroid in a rapid, non-invasive fashion. The technology dates back to 2005, when researchers demonstrated that blood flow could be visualized using swept-source OCT (SS ...

Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]

, 2015
Multi-heme cytochromes are employed by a range of microorganisms to transport electrons over distances of up to tens of nanometers. Perhaps the most spectacular utilization of these proteins is in the reduction of extracellular solid substrates ...
