Phase transitions in tumor growth: II prostate cancer cell lines

JA Llanos-Pérez, A Betancourt-Mar… - Physica A: Statistical …, 2015 - Elsevier
We propose a mechanism for prostate cancer cell lines growth, LNCaP and PC3 based on
a Gompertz dynamics. This growth exhibits a multifractal behavior and a “second order” …

Phase transitions in tumor growth: III vascular and metastasis behavior

JA Llanos-Pérez, JA Betancourt-Mar, G Cocho… - Physica A: Statistical …, 2016 - Elsevier
We propose a mechanism for avascular, vascular and metastasis tumor growth based on a
chemical network model. Vascular growth and metastasis, appear as a hard phase transition …

Phase transitions in tumor growth: IV relationship between metabolic rate and fractal dimension of human tumor cells

JA Betancourt-Mar, JA Llanos-Pérez, G Cocho… - Physica A: Statistical …, 2017 - Elsevier
By the use of thermodynamics formalism of irreversible processes, complex systems theory
and systems biology, it is derived a relationship between the production of entropy per unit …

Phase transitions in tumor growth VI: Epithelial–Mesenchymal transition

…, DJ Rodriguez, S Montero, JA Betancourt-Mar… - Physica A: Statistical …, 2018 - Elsevier
Herewith we discuss a network model of the epithelial–mesenchymal transition (EMT) based
on our previous proposed framework. The EMT appears as a “first order” phase transition …

Entropy production: evolution criteria, robustness and fractal dimension

JA Betancourt-Mar, M Rodríguez-Ricard… - Revista mexicana de …, 2016 - scielo.org.mx
It was proved through Rossler model, where the funnel case is more robust tan spiral chaos,
the entropy production per unit time is a Lyapunov's function on the space of the control …

Theoretical models for chronotherapy: periodic perturbations in funnel chaos type

JA Betancourt-Mar, JM Nieto-Villar - Mathematical Biosciences & …, 2007 - aimsciences.org
In this work, the Rössler system is used as a model for chronotherapy. We applied a periodic
perturbation to the y variable to take the Rössler system from a chaotic behavior to a simple …

The Rössler system as a model for chronotherapy

JA Betancourt-Mar… - Journal of Physics …, 2005 - iopscience.iop.org
The biological systems are opened and are kept far from thermodynamics equilibrium. For
these reasons, biological systems are always exposed to external perturbations, which may …

Chronotherapy of cancer: periodic perturbations in vascular growth and metastasis

…, RR Martin, JA Betancourt-Mar… - Biological rhythm …, 2019 - Taylor & Francis
A non-autonomous model was developed for vascular tumor growth and cancer metastasis
under periodic perturbations that simulate chronotherapy. It was found that for a critical …

[PDF][PDF] Chronotherapy of cancer: Epithelial-Mesenchymal transition

…, DJ Rodríguez, E Silva, JA Betancourt-Mar… - MOJ Gerontol …, 2019 - academia.edu
Metastasis is resistant to conventional therapies and the main cause of death by cancer. In
this article we discuss a non-autonomous model for the stage of cancer metastasis in which a …

Metastasis Models: Thermodynamics and Complexity

A Guerra, JA Betancourt-Mar, JA Llanos-Pérez… - Systems Biology, 2023 - Springer
The thermodynamic formalism of nonequilibrium systems together with the theory of complex
systems and systems biology offer an appropriate theoretical framework to explain the …
