High-Throughput Microfluidic-Mediated Assembly of Layer-by-Layer Nanoparticles. [PDF]

open access: yesAdv Funct Mater
The layer‐by‐layer (LbL) assembly of polymer films on nanoparticle (NP) surfaces is a promising technique for targeted drug delivery. Despite its success in preclinical mouse models, a current good manufacturing practices (cGMP) compliant, clinical‐scale production method has been lacking.

Toward a New Nodal Pricing Policy of the Brazilian Transmission System Considering Multiple Hydrological Scenarios

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2022, Issue 1, 2022., 2022
This paper presents a new method for allocating transmission system costs in hydro prevailing energy markets. The proposed approach is based on nodal pricing, and it considers multiple hydrological scenarios obtained from optimized energy models. These models are much closer to the operational reality of hydro dominant systems and more adequate to the ...

Differences in the metabolite composition and mechanical properties of extracellular vesicles secreted by hepatic cellular models

open access: yesJournal of Extracellular Vesicles, Volume 8, Issue 1, December 2019., 2019
ABSTRACT Liver constitutes the major metabolic factory in the organism and is involved in the synthesis, secretion and clearance of many blood‐circulating molecules. Previously, we have characterised the protein and RNA cargo of extracellular vesicles (EVs) secreted by two hepatic cellular models, a mouse hepatocyte progenitor cell line (MLP29) and ...

Evaluation of Cocktails with Recombinant Proteins of Mycobacterium bovis for a Specific Diagnosis of Bovine Tuberculosis

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
The Delayed type hypersensitivity skin test (DTH) and interferon‐gamma assay are used for the diagnosis of bovine tuberculosis (TBB). The specificity of these diagnoses, however, is compromised because both are based on the response against purified protein derivative of Mycobacterium bovis (PPD‐B).
