Therapeutic properties of VO(dmpp)2 as assessed by in vitro and in vivo studies...
Domingues, N.; Pelletier, J.; Ostenson, C.-G.; Castro, M.M.C.A.The bis(1,2-dimethyl-3-hydroxy-4-pyridinonato)oxidovanadium(IV), VO(dmpp)2, has shown anti-diabetic effects by in vitro studies in Wistar (W) rat adipocytes and in vivo in obese Zucker rats. The aim of this work is to confirm the therapeutic properties of VO(dmpp)2 in non-obese type 2 diabetic Goto-Kakizaki (GK) rats. An in vivo study was carried out, treating W and GK rats during 21 days with a daily dose of V...

Detection of the Epstein-Barr virus in blood and bone marrow mononuclear cells ...
Marques, H; Catarino, R; Domingues, N; Barros, E; Portela, C; Almeida, MI; Costa, S; Reis, RM; Medeiros, R; Longatto-Filho, AThe Epstein-Barr virus (EBV) is associated with a large spectrum of lymphoproliferative diseases. Traditional methods of EBV detection include the immunohistochemical identification of viral proteins and DNA probes to the viral genome in tumoral tissue. The present study explored the detection of the EBV genome, using the BALF5 gene, in the bone marrow or blood mononuclear cells of patients with diffuse large B...

Carvalho, A; Cunha, C; Almeida, AJ; Osório, NS; Saraiva, M; Teixeira-Coelho, M; Pedreiro, S; Torrado, E; Domingues, N; Gomes-Alves, AG; Marques, ANon-Hodgkin lymphoma (NHL) has been associated with immunological defects, chronic inflammatory and autoimmune conditions. Given the link between immune dysfunction and NHL, genetic variants in toll-like receptors (TLRs) have been regarded as potential predictive factors of susceptibility to NHL. Adequate anti-tumoral responses are known to depend on TLR9 function, such that the use of its synthetic ligand is b...

Mixing in single screw extrusion : modelling and optimization
Domingues, N.Tese de doutoramento ; Given the importance of mixing in polymer processing, the aim of this work is to implement a mathematical model for quantifying the mixing behaviour in single screw extruders. The model developed considers the incorporation of solid or liquid additives into a polymeric matrix. For this purpose, the existing numerical routines capable of describing the flow in the melting and melt conveyi...
Global mixing indices for single screw extrusion
Domingues, N.; Gaspar-Cunha, A.; Covas, J. A.The present work presents numerical simulations of dispersive and distributive mixing of a two phase system being processed in a single screw extruder under various conditions. Models were developed to quantify the degree of mixing of liquid-liquid and solids-liquid systems, for a given set of material properties, operating conditions and extruder geometry.
Numerical and experimental study of agglomerate dispersion in polymer extrusion
Domingues, N.; Gaspar-Cunha, A.; Covas, J. A.; Camesasca, M.; Kaufman, M.; Manas-Zloczower, IcaA model for agglomerate dispersion in screw extruders was developed and superimposed on the flow patterns as simulated using the FIDAP software. A particle tracking algorithm with an adaptive time step was used to follow the agglomerates trajectory. Along this flow path, the breakup probability was estimated using a Monte Carlo method and in conjunction with the local fragmentation number. Particle size distrib...
