Modeling and Simulation of a Bacterial Biofilm That Is Controlled by pH and Protonated Lactic Acids

Computational and Mathematical Methods in Medicine, Volume 9, Issue 1, Page 47-67, 2008., 2008
We present a mathematical model for growth and control of facultative anaerobic bacterial biofilms in nutrient rich environments. The growth of the microbial population is limited by protonated lactic acids and the local pH value, which in return are altered as the microbial population changes.

Stability Analysis of a Model of Atherogenesis: An Energy Estimate Approach

Computational and Mathematical Methods in Medicine, Volume 9, Issue 2, Page 121-142, 2008., 2008
Atherosclerosis is a disease of the vasculature that is characterized by chronic inflammation and the accumulation of lipids and apoptotic cells in the walls of large arteries. This disease results in plaque growth in an infected artery typically leading to occlusion of the artery. Atherosclerosis is the leading cause of human mortality in the US, much

Three-dimensional modeling of tumor angiogenesis: endothelial cell progression and therapeutic implications

Open Mathematics
We propose a three-dimensional mathematical model describing the dynamics of endothelial cells during tumor-induced angiogenesis. This framework extends our earlier one- and two-dimensional formulations by incorporating the three-dimensional spatial ...
