Who is interested in the use of propositional logic for explaning some particularities of monosynapsis?

Sure.
Is an importan field. You have to think about it.

Why?

Postby GegnianMD » Sun Dec 30, 2007 5:09 pm

Why mathematical medicine is not applied in a massive scale?

Wich one is the more certain answer?

1. Inexistence of political support from estates.
2. Investigators do not are informed about this interdisciplinary field of searching.

If you can, express mathematically.

Crypt dynamics and colorectal cancer: advances in mathematical
modelling.

Mathematical modelling forms a key component of systems biology,
offering insights that complement and stimulate experimental studies.
In this review, we illustrate the role of theoretical models in
elucidating the mechanisms involved in normal intestinal crypt dynamics
and colorectal cancer. We discuss a range of modelling approaches,
including models that describe cell proliferation, migration,
differentiation, crypt fission, genetic instability, APC inactivation
and tumour heterogeneity. We focus on the model assumptions,
limitations and applications, rather than on the technical details. We
also present a new stochastic model for stem-cell dynamics, which
predicts that, on average, APC inactivation occurs more quickly in the
stem-cell pool in the absence of symmetric cell division. This suggests
that natural niche succession may protect stem cells against malignant
transformation in the gut. Finally, we explain how we aim to gain
further understanding of the crypt system and of colorectal
carcinogenesis with the aid of multiscale models that cover all levels
of organization from the molecular to the whole organ.

Department of Mathematics, University of California, Irvine, CA 92697, USA. Division patterns or mammalian tissues, like every other feature of life, have been subject to evolutionary pressures throughout the natural history. A particular and very important design principle that we discuss in this paper is the protective role of tissue architecture against cancer. We present a stochastic dynamical model of cell renewal of epithelial tissue (colonic crypts) which explicitly includes asymmetric indefinite divisions of stem cells and symmetric, finite divisions of daughter cells. We find that the hierarchical structure of crypts plays a protective role against accumulation of double-mutants. We argue that daughter cells, and not only stem cells, can play a role in carcinogenesis. Our model also predicts the optimum number of stem cells per crypt. In most cases, higher numbers of stem cells per crypt correspond to lowering the chance of colon cancer initiation (except if mutation rates associated with daughter cells are a lot lower than those associated with stem cells). Finally, we argue that the evolutionarily optimum which corresponds to a large number of stem cells per crypt, pushes the onset of cancer to an older age, but it actually acts against older individuals by increasing their chance of developing cancer.
