Opis:
Model organisms are essential to study the genetic basis of human diseases. Transgenic mammalian models, especially genetic knock-out mice have catalysed the progress in this area. To continue the advancement, further sophisticated and refined models are crucially needed to study the genetic basis and manifestations of numerous human diseases. Coinciding with the start of the new era of post-genomic research, new tools for establishment of transgenesis, such as nuclear transfer and gene targeting in somatic cells, have become available, offering a unique opportunity for the generation of transgenic animal models. The new technology provides important tools for comparative functional genomics to promote the interpretation and increase the practical value of the data generated in numerous mouse models. This paper discusses the state-of-the-art of the nuclear replacement technology and presents future perspectives.

Opis:
This review addresses the need to evaluate the biological effects of novel foods, how this can be achieved and the role of animal models in this process. The selection of an appropriate model or combination of approaches is most important, together with an awareness of the shortcomings of that particular method. In mammals the gastrointestinal tract not only acts as the site of absorption of nutrients and non-nutrients, but provides a protective barrier between the environment and the body. As such this interface is exposed to relatively high concentrations of the individual chemicals that are dietary components. It is therefore essential to understand how novel foods can change the structure, growth and function of the gut in particular. Effects may be both beneficial and detrimental and have an impact on the function of other organs in the body. However, due to the wide-ranging implications of this broad topic, the discussion here will focus on events within the gastrointestinal tract, in the context of the evaluation of novel foods.

Opis:
In this paper we investigate a mathematical model of cancer invasion of tissue, which incorporates haptotaxis, chemotaxis, proliferation and degradation rates for cancer cells and the extracellular matrix, kinetics of urokinase receptor, and urokinase plasminogen activator cycle. We solve the model using spectrally accurate approximations and compare its numerical solutions with laboratory data. The spectral accuracy allows to use low-dimensional matrices and vectors, which speeds up the computations of the numerical solutions and thus to estimate the parameter values for the model equations. Our numerical results demonstrate correlations between numerical data computed from the mathematical model and in vivo tumour growth rates from prostate cell lines.
