Gramicidin is a pore-forming peptide which exhibits lethal properties against a large spectrum of cells. It forms monovalent cation-specific channel in the lipid bilayer of a cellular membrane with limited permeability to anions or polyvalent cations. Both ions and water move through the pore which is formed by the peptide backbone. We detected formation of pores induced by the dimerization of gramicidin...
The electrodynamic and numerical analysis of eigen Q-factor of electromagnetic modes of H-type (as the most high-quality) in waveguide junction of cylindrical-rectangular waveguides filled by dielectric have been carried out in this work. The comparative characteristic of eigen Q-factor waveguide junctions of various cross-section was given: cylindrical-radial waveguides, rectangular-rectangular waveguides,...
