Interferon gamma rebalances immunopathological signatures in chronic granulomat...
Bruno, M.; Kröger, C.; Ferreira, A. V.; Zhang, B.; Röring, R. J.; Liu, R.; van der Made, C. I.; van Rhijn, N.; Groh, L.; Klück, V.; Janssen, N. A. F.Chronic granulomatous disease (CGD) is a primary immunodeficiency characterized by recurrent life-threatening infections and hyperinflammatory complications. It is caused by mutations in the reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex and the consequent loss of reactive oxygen species (ROS) production. Recombinant human interferon gamma (rIFN-γ) prophylaxis reduces the risk of se...
Collective processes in a large atomic laser cooling experiment
Rodrigues, J. D.; Rodrigues, J. A.; Ferreira, A. V.; Mendonça, J. T.We introduce an hydrodynamic description of a laser cooled gas. In large traps, with as much as 10(10) atoms, multiple scattering of light leads to a collective interaction field which can be described by a Poisson-like equation, included in our formulation. A behaviour similar to a one-component trapped plasma should then be observed. By considering equilibrium conditions we extract the theoretical atomic dens...
Orange IV stabilizes silk fibroin microemulsions
Ferreira, A. V.; Volkov, Vadim; Abreu, Ana S.; Azóia, Nuno G.; Botelho, C. M.; Paulo, Artur CavacoSilk fibroin (SF) is a natural biopolymer that has been extensively studied in various applications due to its impressive mechanical properties and biocompatibility. Recently, SF-based particles have been proposed as controlled drug delivery systems. A new and efficient method to prepare SF microemulsions (SF-MEs) was developed by oil-in-water emulsions using high-pressure homogenization to promote emulsificati...

Ferreira, A. V.; Volkov, Vadim; Vasconcelos, Andreia; Abreu, Aana S.; Botelho, C. M.; Paulo, Artur CavacoSilk Fibroin (SF) has been extensively studied for various applications due to its impressive mechanical properties and biocompatibility. Recently, SF based-particles have been proposed as controlled drug delivery systems. A new and efficient method was developed to prepare SF nanoparticles (SF-NPs) by high pressure homogenization (HPH) emulsification, in oil-in-water emulsions (o/w). During the NPs production ...
