The purpose of this work is to study the changes of the bioimpedance from its 'in vivo' value to the values measured in a few hours after the excision from the body. The evolution of electrical impedance with time after surgical extraction has been studied on two porcine organs: the liver and the kidney. Both in vivo and ex vivo measurements of electrical(More)
PM2000 is a ferritic alloy obtained by powder metallurgy and is being investigated for potential applications as a biomaterial. This work aimed to assess the biological compatibility and to determine the influence of the processing route and further recrystallisation treatment on the magnetic behaviour. The magnetic behaviour has been analysed as a function(More)
This paper reviews the effect of organic and inorganic coatings on magnetic nanoparticles. The ferromagnetic-like behaviour observed in nanoparticles constituted by materials which are non-magnetic in bulk is analysed for two cases: (a) Pd and Pt nanoparticles, formed by substances close to the onset of ferromagnetism, and (b) Au and ZnO nanoparticles,(More)
Calculations of the induced currents created in the human body by external electromagnetic fields would be more accurate provided that more realistic experimental values of the electrical properties of the body were available. The purpose of this work is to experimentally obtain values for the conductivity of living organs in conditions close to the real(More)
We report a 33 year old male admitted after a traffic accident with a painful abdomen and an open ankle fracture. An abdominal CAT scan showed a splenic laceration and free ascites. A conservative treatment was decided considering that the patient was hemodynamically stabilized. Seven days later, the patient appeared hypotense and with severe pain and was(More)
For decades, it has been known that malignant cells have a propensity to metabolize glucose to lactate in the presence of oxygen. Normal lymphoid cells generate ATP from glycolysis and oxidative phosphorylation (OxPhos). After activation, B-lymphocytes proceed via differentiation programs to produce metabolically active subsets to ensure clonal expansion(More)
