Journal ArticleDOI
Binding Strength Between Cell Adhesion Proteoglycans Measured by Atomic Force Microscopy
U. Dammer,Octavian Popescu,Peter Wagner,Dario Anselmetti,Hans-Joachim Güntherodt,Gradimir N. Misevic +5 more
TL;DR: Atomic force microscopy was used to measure the binding strength between cell adhesion proteoglycans from a marine sponge, and high intermolecular binding forces are likely to form the basis for the integrity of the multicellular sponge organism.
Journal ArticleDOI
Synergistic antibacterial activity of chitosan-silver nanocomposites on Staphylococcus aureus.
TL;DR: It is found that chitosan and silver nanoparticles act synergistically against two strains of Gram-positive Staphylococcus aureus (S. aureus) and the bionanocomposites exhibit higher antibacterial activity than any component acting alone.
Journal ArticleDOI
The two soluble forms of the lipopolysaccharide receptor, CD14: Characterization and release by normal human monocytes
J J Durieux,Natalio Vita,Octavian Popescu,F. Guette,J Calzada-Wack,Reinhold Munker,Reinhold E. Schmidt,Jan H. Lupker,P. Ferrara,H. W. L. Ziegler-Heitbrock +9 more
TL;DR: It is found that sCD14β is released faster than sCD 14α and that the release of the latter is a lengthy process, and may be useful for better understanding of variations in sCD 13 levels in pathological conditions and the contribution of each s CD 14 in scpsis and other, as yet unknown functions.
Journal ArticleDOI
p-(Chloromercuri)benzenesulfonate binding by membrane proteins and the inhibition of water transport in human erythrocytes.
TL;DR: Results indicate that band 4.5 proteins as well as band 3 have to be considered as playing a role in water transport, in contrast to previous experiments.
Journal Article
Water permeability in human erythrocytes: identification of membrane proteins involved in water transport.
Gheorghe Benga,Octavian Popescu,Borza,Victor I. Pop,Ana Muresan,Mocsy I,Brain A,John M. Wrigglesworth +7 more
TL;DR: Inhibition of water transport by sulfhydryl reagents does not induce major morphological changes in the cells as assessed by freeze-fracture and scanning electron microscopy.
