Surface bioconjugation of antimicrobial peptides (AMP) onto nanoparticles (AMP-NP) is a complex, multistep, and time-consuming task. Herein, a microfluidic system for the one-pot production of AMP-NP was developed. Norbornene-modified chitosan was used for NP production (NorChit-NP), and thiolated-AMP was grafted on their surface via thiol-norbornene "photoclick" chemistry over exposure of two parallel UV LEDs....



Imidazoline receptors. Historic review and current status of knowledge.

Moura, D

After the initial demonstration, by Ruffolo in 1977, that imidazolines and phenethylamines do not interact in the same manner with adrenoceptors, a different class of receptors (imidazoline-preferring receptors) was identified. They are present in the brain stem and in several tissues at the periphery. This imidazoline-preferring receptor is believed to be the target of the anti-hypertensive effect of clonidine...
