Nanoscale Analysis Reveals the Maturation of Neurodegeneration-Associated Protein Aggregates: Grown in mRNA Granules then Released by Stress Granule Proteins

05-Jul-2017 | Sanae Abrakhi; Dmitry A. Kretov; Bénédicte Desforges; Ioana Dobra; Ahmed Bouhss; David Pastré; Loic Hamon, ACS Nano, 2017

TDP-43 and FUS are two mRNA-binding proteins associated with neurodegenerative diseases that form cytoplasmic inclusions with prion-like properties in affected neurons. Documenting the early stages of the formation of TDP-43 or FUS protein aggregates and the role of mRNA stress granules that are ...

Synthesis and Characterization of Epoxy Thermosetting Polymers from Glycidylated Organosolv Lignin and Bisphenol A

14-Dec-2016 | Lena Charlotte Over, Etienne Grau, Stéphane Grelier, Michael A. R. Meier, Henri Cramail, Macromolecular Chemistry and Physics, 2016

Diglycidylether of bisphenol A and isophorone diamine (IPDA) are industrially used for polyepoxide curing. Herein, glycidylated Organosolv lignin (GOL) is cured with diglycidyl ether of bisphenol A and IPDA for intensive studies. Organosolv lignin (OL) is therefore first glycidylated with ...

Experimental Investigation of Reaction Confinement Effects on Coke Yield in Coal Pyrolysis

01-Aug-2016 | Jeffrey LeBlanc; John Quanci; Marco J. Castaldi, Energy & Fuels, 2016

The pyrolysis of agglomerating coal was analyzed by thermogravimetric analysis (TGA) coupled to microgas chromatography (μGC) to determine the effects of reactor confinement on solid product yield, tar evolution, and gas composition. The primary volatile products generated from pyrolysis are ...
