Carbon nanotubes as gene carriers: Focus on internalization pathways related to functionalization and properties
Abstract Carbon nanotubes represent promising transporters for delivery of DNA and other biomolecules into living cells. Various methods of CNTs surface functionalization have been developed. These are essential to improve CNTs dispersibility and permit their interactions with biological structures that broaden their use in advanced biomedical applications. The present review discusses the different single walled carbon nanotubes and multiwalled carbon nanotubes functionalization methods, leading to the formation of optimized and functionalized-CNT complexes with DNA. F-CNTs are recognized as efficient and promising gene carriers. Emphasis is then placed on the processes used by f-CNTs/DNA …
The Janus face of chlorogenic acid on vascular reactivity: A study on rat isolated vessels
Abstract Background Chlorogenic acid (CGA), the main polyphenol contained in coffee, is a major contributor to dietary polyphenol intake. Few studies reported its anti-hypertensive properties but the mechanisms are still indefinite. Purpose The present study assessed the direct effect of CGA in endothelium denuded or intact aortic rings from male Wistar rats and the mechanisms involved. Methods/Results CGA induced a direct endothelium-dependent relaxation that was significantly reduced by L-NAME (10 −4 M), indomethacin (10 −5 M) and combination of apamin (10 −7 M) and charybdotoxin (10 −7 M). Incubation of rings with CGA induced a dual effect on agonist-induced vasorelaxation. At 10 −6 …
