The majority of genetic engineering methods are based on delivery of foreign nucleic acids
into intact cells (I). To date, a number of techniques havebeen developed for DNA …

Introduction Polyamines (putrescine, spermidine and spermine) are ubiquitous polycationic
metabolites in prokaryotic and eukaryotic cells. Their roles in the regulation of major …

To characterize the specificity of ion binding to phospholipids in terms of headgroup
structure, hydration and lyotropic phase behavior we studied 1-palmitoyl-2-oleoyl …

The field of liposome (vesicle) research has expanded considerably over the last 30 years.
In physical chemical terms liposomes have many of the characteristics of colloidal particles …

Polyphosphoinositides (PPI) and in particular PI (4, 5) P 2, are among the most highly
charged molecules in cell membranes, are important in many cellular signaling pathways …

Membrane fusion induced by ions and its associated membrane property, surface dielectric
constant, were studied with the use of acidic and neutral phospholipid vesicles. The fusion of …

Zinc-chelated poly (1-vinylimidazole)(PVIm-Zn) and a carbohydrate ligand polycation, a poly
(l-lysine) conjugated with lactose molecules (PLL-Lac), have formed DNA ternary complexes …

Lanthanide ions are the only known blockers of permeabilization by electric pulses of
nanosecond duration (nsEP), but the underlying mechanisms are unknown. We employed …
