2Dendrimer nanocarriers drug action: perspective for neuronal pharmacology显示文摘General aspects:Currently,several strategies have been used to overcome common problems found in pharmacological therapies,such as insolubility,reduced bioavailability and low specificity of drugs.One of the most promising alternatives proposed is the use of dendrimeric drug nanocarriers,polymeric chemical structures of diverse nature that contain,transport and deliver the desired drug in biological systems.One of the dendrimers that has been most successfully used is based on polyamidoamine(PAMAM).PAMAM are organized from a central molecule of ethylenediamine that gives way to expansive growing layers(generations)terminating in a surface of primary amines that are positively charged at physiological p H.This architecture determines the presence of intramolecularFelipe Vidal Leonardo Guzman 2015Neural Regeneration Research2015,10,7:0
3Lignocellulosic Micro and Nanofibrillated Cellulose Produced by Steam Explosion for Wood Adhesive Formulations显示文摘The reinforcing impact of Lignocellulosic micro and nanofibrillated cellulose(L-MNFCs)obtained from Eucalyp-tus Globulus bark in Urea-Formaldehyde UF adhesive was tested.L-MNFCs were prepared by an environmentally friendly,low-cost process using a combination process involving steam explosion followed by refining and ultra-fine grinding.Obtained L-MNFCs showed a web-like morphology with some aggregates and lignin nanodroplets.They present a mixture of residual fibers and fine elements with a width varying between 5 nm to 20μm,respec-tively.The effects of the addition of low amounts of L-MNFCs(1%wt.)on the properties of three different adhe-sives(Urea-Formaldehyde UF,Phenol-Formaldehyde PF,and Tannin-Hexamine TH)were studied by the evolution of the pH,the viscosity,and the mechanical properties.Results showed that the viscosity of PF and UF adhesives increased with the addition of L-MNFCs,unlike TH.Meanwhile,the addition led to better mechan-ical behavior for the three adhesives.Particleboards were then prepared using modified UF with L-MNFCs and tested.Results showed that an amount of 1%wt.of L-MNFCs was sufficient to increase the internal bonding by≈67%,the modulus of elasticity by≈43%,and the modulus of rupture by≈29%.Saad Nader Felipe Guzman Raphael Becar Cesar Segovia Cecilia Fuentealba Miguel Peirera Evelyne Mauret Nicolas Brosse 2022Journal of Renewable Materials2022,10,2:0
