Severity of nicotine dependence modulates cue-induced brain activity in regions involved in motor preparation and imagery
RationaleIn nicotine-dependent subjects, cues related to smoking elicit activity in brain regions linked to attention, memory, emotion and motivation. Cue-induced brain activation is associated withExpand

Effects of external electrical fields on cell membranes
Abstract Dielectric breakdown of the cell membrane is observed when the membrane potential is taken rapidly (in μs) to a value of the order of 1 V. In giant algal cells a potential differences acrossExpand

Pressure probe technique for measuring water relations of cells in higher plants.
A new method is described for continuously measuring cell turgor pressure (P), hydraulic conductivity (L(p)), and volumetric elastic modulus (epsilon) in higher plant cells, using a pressure probe.Expand

Hydrogel-based non-autologous cell and tissue therapy.
Many diseases are closely tied to deficient or subnormal metabolic and secretory cell functions. Milder forms of these diseases can be managed by a variety of treatments. However, it is oftenExpand

Kinetics of pore size during irreversible electrical breakdown of lipid bilayer membranes.
The kinetics of pore formation followed by mechanical rupture of lipid bilayer membranes were investigated in detail by using the charge-pulse method. Membranes of various compositions were chargedExpand
