  • O(N) SCGB solvation models: first “blood”

    O(N) SCGB solvation models: first “blood”

    Not only our recently introduced surface charges generalized Born (SCGB) models prove to be reasonable in terms of providing solutions to Poisson Boltzmann equation in complicated geometries, such as biomolecules. By getting rid of the standard expression for the solvation energy we are able to...

  • Protein solvation energies and GB surface charges: perfect match!

    Protein solvation energies and GB surface charges: perfect match!

    Up to now, there have been at least two schools of thoughts among those trying to calculate electrostatics part of solvation energies. Half of the folks believe that only an exact solution of the Poisson equation can be better than the solution of the Poisson...

    ISTC/NIH-NIAID meeting, Moscow, 17.11.09

    As part of recent efforts to expand cooperation in health, the U.S. National Institute of Allergy and Infectious Diseases (NIAID) is interested in learning more about the spectrum of biomedical research and expertise in the Russian Federation. In particular, efforts focusing on detection of drug...

  • How to use Born surface charges to calculate solvation energy?

    How to use Born surface charges to calculate solvation energy?

    We have recently established a relation between the Generalized Born methods and finite elements surface electrostatics. Indeed, if the Generalized Born solvation energy is interpreted as a (though approximate) definition of the reaction field potential, then the boundary condition defines the surface chages in terms...

    Experimental siRNA complex uptake without transfection reagents

    Normally siRNA do not penetrate cell membranes without transfection reagents. In Quantum Pharmaceutical we developed a new nanoscale complex with ability to transport siRNA over cell membranes of a cancer cell. In experiments with fluorescent siRNA molecules coupled with our proprietory transport system we conformed...
