COMSOL Multiphysics® as a Tool for Reducing Animals in Biomedical Research: An Application in Dermatology

F. Rossi[1] and R. Pini[1]
[1]Istituto di Fisica Applicata “Nello Carrara”, Consiglio Nazionale delle Ricerche, Firenze, Italy

In biomedical research the use of animal models gives rise to several ethical problems. COMSOL Multiphysics® may be used as a non-animal technique, very useful in overcoming all these concerns. In this presentation a particular application in dermatology is shown. Bioheat equation ... Saiba Mais

3-Dimensional Blood Cooling Model inside a Carotid Bifurcation

R. Sikorski[1], T. Merrill[1]
[1]Rowan University, Glassboro, NJ, USA

Stroke is caused by an interruption of brain blood supply and is one of the leading causes of death and disability. A mild reduction of 2-5°C in tissue temperature through hypothermia has shown reduced tissue infarct size, increased tissue recovery, and positive neurological effects. ... Saiba Mais
