Molecular Models of Diseases Kinetics

It is generally acknowledged that transmittable spongiform encephaloathies diseases (TSE), such
as scrapie, kuru and kind of Creutzfeld-Jacob disease are related to formation of misfolded fibril-like
prion proteins.  Using a molecular model of the aggregation kinetics we describe the kinetics of the
prion growth and derived the size distribution of the fibril aggregates.

  My main  publications on the topic are:

Brownian Motion of Biomolecules

Biological functions of biomolecules in nature are intrinsically related to their mobility, i.e. to
the properties of the Brownian motion of these particles. Usually they are strongly  charged or
have a large electrical dipolar moment.  The intensive electrostatic interactions between the
charged and/or dipolar biomolecules or between the macromolecules and the polar solvent
influence significantly their Brownian Motion .
