as a Model System to Assess the Effect of Epstein-Barr Virus DNA on Inflammatory Gut Diseases.

Front Immunol 2021 22;12:586930. Epub 2021 Mar 22.

Department of Experimental Pathology and Immunology, American University of Beirut, Faculty of Medicine, Beirut, Lebanon.

The Epstein-Barr virus (EBV) commonly infects humans and is highly associated with different types of cancers and autoimmune diseases. EBV has also been detected in inflamed gastrointestinal mucosa of patients suffering from prolonged inflammation of the digestive tract such as inflammatory bowel disease (IBD) with no clear role identified yet for EBV in the pathology of such diseases. Since we have previously reported immune-stimulating capabilities of EBV DNA in various models, in this study we investigated whether EBV DNA may play a role in exacerbating intestinal inflammation through innate immune and regeneration responses using the model.

Atomic Resolution Map of Hierarchical Self-Assembly for an Amyloidogenic Protein Probed through Thermal N-R Correlation Matrices.

J Am Chem Soc 2021 Mar 18;143(12):4668-4679. Epub 2021 Mar 18.

Department of Biochemistry and Biomedical Sciences, McMaster University, Hamilton ON L8S4M1, Canada.

Soluble oligomers formed by amyloidogenic intrinsically disordered proteins are some of the most cytotoxic species linked to neurodegeneration. Due to the transient and heterogeneous nature of such oligomeric intermediates, the underlying self-association events often remain elusive. NMR relaxation measurements sensitive to zero-frequency spectral densities (J(0)), such as the N - R rates, are ideally suited to map sites of self-association at atomic resolution without the need of exogenous labels.

Biodegradable PLA/PBSA Multinanolayer Nanocomposites: Effect of Nanoclays Incorporation in Multinanolayered Structure on Mechanical and Water Barrier Properties.

Nanomaterials (Basel) 2020 Dec 20;10(12). Epub 2020 Dec 20.

Normandie Univ, UNIROUEN, INSA Rouen, CNRS, PBS, 76000 Rouen, France.

Biodegradable PLA/PBSA multinanolayer nanocomposites were obtained from semi-crystalline poly(butylene succinate--butylene adipate) (PBSA) nanolayers filled with nanoclays and confined against amorphous poly(lactic acid) (PLA) nanolayers in a continuous manner by applying an innovative coextrusion technology. The cloisite 30B (C30B) filler incorporation in nanolayers was considered to be an improvement of barrier properties of the multilayer films additional to the confinement effect resulting to forced assembly during the multilayer coextrusion process. 2049-layer films of ~300 µm thick were processed containing loaded PBSA nanolayers of ~200 nm, which presented certain homogeneity and were mostly continuous for the 80/20 wt% PLA/PBSA composition.
