    Niekt贸re liotropowe uk艂ady ciek艂okrystaliczne tworz膮ce ta艣mowe uk艂ady micelarne maj膮 zdolno艣膰 tworzenia kompleks贸w z bia艂kami pod warunkiem mo偶liwo艣ci penetracji do wn臋trza bry艂y bia艂kowej. Mo偶liwo艣膰 tak膮 stwarzaj膮 bia艂ka o niestabilnej strukturze w tym g艂贸wnie bia艂ka patologiczne a tak偶e cz臋艣膰 bia艂ek nale偶膮cych do bia艂ek ostrej fazy. Modyfikacja 艂adunku bia艂ka w wyniku kompleksowania mo偶e by膰 ujawniona w rozdziale elektroforetycznym. Dwukierunkowy rozdzia艂 elektroforetyczny z dodatkiem liganda supramolekularnego w drugim prostopad艂ym kierunku rozdzia艂u pozwala na ujawnienie i izolacj臋 kompleks贸w z ciek艂okrystalicznym ligandem. Otwiera to istotne mo偶liwo艣ci diagnostyczne. Oczekiwane jest opracowanie numerycznej techniki ilo艣ciowej oceny proporcji ujawnionych frakcji bia艂kowych. Wi膮zanie ligand贸w ciek艂okrystalicznych okazuje si臋 te偶 aktualne w przypadku kompleksowania ich przez z艂ogi amyloidowe. Czerwie艅 Kongo jest w tym przypadku markerem specyficznym.Some lyotropic liquide crystals of ribbon-like micellar structure form complexes with proteins of unstable structure due to possible penetration to their interior. Misfolded proteins and some acute phase serum proteins belong to that group. The altered charge of proteins engaged in complexation which becomes modified by the charge of bound ligand affects electrophoretic migration and allows differentiation of ubnormal proteins from among serum proteins. Two-dimensional agarose electrophoresis of serum proteins undergone complexation with supramolecular ligand after perpendicular reorganization of migration fulfils the requirement. The exposure of misfolded proteins and their quantitative analysis has a significant diagnostic meaning. Elaboration of numerical analysis is expected. Ligands in form of liquide crystals have been found to be bound to amyloids. Congo red appeared to be the specific marker for recognition of amyloid fibrils. This type of ligand seems to be the new category of ligands complexes in form of multimolecular system

    Support for Cooperative Experiments in e-Science: From Scientific Workflows to Knowledge Sharing

    The term e-Science describes computational and data-intensive science. It has become a complementary experiment paradigm alongside the traditional in vivo and in vitro experiment paradigms. e-Science opens new doors for scientists and with it, it exposes a number of challenges such as how to organize huge datasets and coordinate distributed execution. For these challenges, a plethora of technologies and innovations have come together to enable e-Science (Foster and Kesselman 2006). Nowadays, complex scientific experiments designed following the e-Science paradigm are preformed using geographically distributed instruments, data and computing resources. The newly designed scientific experiments are costly, time-consuming, and multidisciplinary. Complex scientific experiments not only require access to geographically distributed hardware and software resources, but also extensive support to foster best practices, dissemination, and re-use
