Indolicidin, a cationic antimicrobial tridecapeptide amide, is rich in proline and tryptophan residues. Its biological activity is intensively studied, but the details how indolicidin interacts with membranes are not fully understood yet. We report here an in situ atomic force microscopic study describing the effect of indolicidin on an artificial supported(More)
Mechanical parameters play a crucial role in proper cellular functions. This article examines the process of the appearance and breaking of adhesion forces during contact between the confluent cerebral endothelial cell layer and a melanoma cell attached to a tipless cantilever. This adhesion is the initial phase of melanoma transmigration through the(More)
Do Russian federal expenditures serve to reduce regional inequality, to insure against exogenous shocks, or to compensate regions for low tax capacity? Do sub-national governments appear to engage in strategic behavior in attempting to influence central governmental transfers? Using a panel data base coving Russia's regions during the period after the(More)
Certain legume plants produce a plethora of AMP-like peptides in their symbiotic cells. The cationic subgroup of the nodule-specific cysteine-rich (NCR) peptides has potent antimicrobial activity against gram-negative and gram-positive bacteria as well as unicellular and filamentous fungi. It was shown by scanning and atomic force microscopies that the(More)

Specific inhibitory reactions of herbicides with photosynthetic reaction centers bound to working electrodes were monitored in a conventional electrochemical cell and a newly designed microfluidic electrochemical flow cell. In both cases, the bacterial reaction centers were bound to a transparent conductive metal oxide, indium-tin-oxide, electrode through(More)
In our previous paper (Nagy et al. in J Biol Chem 285:38811–38817, 2010) by using a multilayered model system, we showed that, from α-casein, aggregates (similar to natural casein micelles) can be built up step by step if Ca-phosphate nanocluster incorporation is ensured between the protein adsorption steps. It remained, however, an open question whether(More)
