Journal ArticleDOI
The extremely halophilic archaeon Halobacterium salinarum R1 responds to potassium limitation by expression of the K+-transporting KdpFABC P-type ATPase and by a decrease in intracellular K+.
TL;DR: H. salinarum R1 was shown to further adapt to K+ limitation by a significant decrease of the intracellular K+ level, which suggests a rather complex mechanism of K+ homeostasis, in which the adaptation of cellular K+ concentrations and the concomitant transcriptional regulation of genes coding for a high-affinity ATP-driven K+ uptake system ensure the essential potassium supply under limiting conditions.
Journal ArticleDOI
Natural lipid extracts and biomembrane-mimicking lipid compositions are disposed to form nonlamellar phases, and they release DNA from lipoplexes most efficiently
TL;DR: The finding that lipid mixtures mimicking biomembrane lipid compositions are superior to pure anionic liposomes in their ability to release DNA from lipoplexes (cationic lipid/DNA complexes) is reported, even though they have a much lower negative charge density.
Journal ArticleDOI
Structural and dynamical studies from bio-mimetic systems: an overview
TL;DR: Fragneto and Rheinstadter as mentioned in this paper used neutron scattering techniques for the characterization of the structure and dynamics of bio-mimetic systems and much progress has been done in recent years since they give the unique access to microscopic structures and dynamics at length scales of intermolecular or atomic distances.
Journal ArticleDOI
Experimental evidence of the electrostatic contribution to membrane bending rigidity
TL;DR: How electrostatics affect the elastic properties of unilamellar bilayers is demonstrated in terms of a mean-field free-energy model for the adsorption of charged surfactants to a lipid bilayer and the electrostatic contribution to membrane bending rigidity is described.
Journal ArticleDOI
Cholesterol and phytosterols effect on sphingomyelin/phosphatidylcholine model membranes - thermodynamic analysis of the interactions in ternary monolayers.
TL;DR: In this paper, the effect of sterols on the condensing of ternary sphingomyelin/DPPC/sterol Langmuir films was analyzed using compression modulus values.
