Male albino rats received a stereotaxic injection of 6-hydroxydopamine (6-OHDA) into the right substantia nigra. Animals demonstrating contralateral rotations 2 weeks postoperatively with apomorphine (0.5 mg/kg i.p.) were treated with L-Dopa (55 mg/kg i.p.), bromocriptine (2 mg/kg i.p.), or polyethylene glycol (vehicle) every 12 h for 30 days. Striatal(More)
In experimental Parkinson's disease, we studied the effects of chronic administration (30 days), withdrawal, and reinstitution of bromocriptine. Dopamine (DA) receptor supersensitivity was produced by 6-hydroxydopamine and reversed by chronic bromocriptine administration. Drug holiday reestablished sensitivity of DA receptors, but reinstitution of(More)
OBJECTIVE A deformable registration technique was developed and evaluated to track and quantify tumor response to radiofrequency ablation for patients with liver malignancies. MATERIALS AND METHODS The method uses the combined power of global and local alignment of pre- and post-treatment computed tomography image data sets. The strategy of the algorithm(More)
Indirect-drive hohlraum experiments at the National Ignition Facility have demonstrated symmetric capsule implosions at unprecedented laser drive energies of 0.7 megajoule. One hundred and ninety-two simultaneously fired laser beams heat ignition-emulate hohlraums to radiation temperatures of 3.3 million kelvin, compressing 1.8-millimeter-diameter capsules(More)
Experiments have recently been conducted at the National Ignition Facility utilizing inertial confinement fusion capsule ablators that are 175 and 165  μm in thickness, 10% and 15% thinner, respectively, than the nominal thickness capsule used throughout the high foot and most of the National Ignition Campaign. These three-shock, high-adiabat, high-foot(More)
We report on the first layered deuterium-tritium (DT) capsule implosions indirectly driven by a "high-foot" laser pulse that were fielded in depleted uranium hohlraums at the National Ignition Facility. Recently, high-foot implosions have demonstrated improved resistance to ablation-front Rayleigh-Taylor instability induced mixing of ablator material into(More)
Correction In our recently published article [1] we made a mistake in describing the contribution of two of the authors. In particular, we indicated that AT helped in designing the study, carried out psychophysical testing, analyzed data and drafted the manuscript and that DCY designed the study, carried out psychophysical testing, analyzed data and helped(More)
