Lourenco W, Reis R, Ruiz-Baier R, Rocha B, Dos Santos R, Lobosco M
Front Physiol . 2022 Jul; 13:888515. PMID: 35860652
Myocarditis is a general set of mechanisms that manifest themselves into the inflammation of the heart muscle. In 2017, more than 3 million people were affected by this disease worldwide,...

Propp A, Gizzi A, Levrero-Florencio F, Ruiz-Baier R
Biomech Model Mechanobiol . 2019 Oct; 19(2):633-659. PMID: 31630280
We propose and analyse the properties of a new class of models for the electromechanics of cardiac tissue. The set of governing equations consists of nonlinear elasticity using a viscoelastic...

Loppini A, Gizzi A, Ruiz-Baier R, Cherubini C, Fenton F, Filippi S
Front Physiol . 2018 Dec; 9:1714. PMID: 30559677
We numerically investigate the role of mechanical stress in modifying the conductivity properties of cardiac tissue, and also assess the impact of these effects in the solutions generated by computational...

Cherubini C, Filippi S, Gizzi A, Ruiz-Baier R
J Theor Biol . 2017 Jul; 430:221-228. PMID: 28755956
We introduce a new model to describe diffusion processes within active deformable media. Our general theoretical framework is based on physical and mathematical considerations, and it suggests to employ diffusion...

J Math Biol . 2015 Jul; 72(6):1441-65. PMID: 26219250
In this paper we analyze the effects of introducing the fractional-in-space operator into a Lotka-Volterra competitive model describing population super-diffusion. First, we study how cross super-diffusion influences the formation of...

Rossi S, Ruiz-Baier R, Pavarino L, Quarteroni A
Int J Numer Method Biomed Eng . 2014 Nov; 28(6-7):761-88. PMID: 25364850
A model for the active deformation of cardiac tissue considering orthotropic constitutive laws is introduced and studied. In particular, the passive mechanical properties of the myocardium are described by the...

Ruiz-Baier R, Gizzi A, Rossi S, Cherubini C, Laadhari A, Filippi S, et al.
Math Med Biol . 2013 Jun; 31(3):259-83. PMID: 23760444
We investigate the interaction of intracellular calcium spatio-temporal variations with the self-sustained contractions in cardiac myocytes. A consistent mathematical model is presented considering a hyperelastic description of the passive mechanical...
