171. Response to "Comment on 'Reinterpretation of the Spectra of Hydrated Co++: An Ab Initio Study'"
Topic: Life Sciences Research
Published: 6/15/2000
Authors: H S. Gilson, Morris Krauss
Abstract: This is a response to comments on a previous paper. Reinterpretation of the Spectra of Hydrated Co++: an ab Initio Study.

172. Effective Fragment Potentials and the Enzyme Active Site
Topic: Life Sciences Research
Published: 5/1/2000
Authors: S E Worthington, Morris Krauss
Abstract: Optimization of the binding conformation of a substrate in an enzyme active site using ab initio quantum chemistry methods are intractable since the active site comprises several hundred atoms. However, the active site can be decomposed into an activ ...

173. Spin-Orbit Configuration Interaction Calculation of the Potential Energy Curves of Iodine Oxide
Topic: Life Sciences Research
Published: 4/6/2000
Authors: S Roszak, Morris Krauss, A B Alekseyev, H P Liebermann, R J Buenker
Abstract: An ab initio cofiguration interaction (CI) study including spin-orbit coupling is carried out for the ground and excited states of the IO radical by employing relativistic effective core potentials. The computed spectroscopic constants are in good a ...

174. Differential Surface Stress of a Tin Oxide Electrode
Topic: Life Sciences Research
Published: 4/1/2000
Authors: Gintaras Valincius, Vytautas Reipa
Abstract: Differential surface stress measurements performed using estance technique and simultaneous measurements of the differential capacitance provide experimental evidence for deviation of n-tin oxide electrode's properties from the electrocapillary relat ...

175. Interrogating Unsupported Lipid Bilayers With Scanning Confocal Single-Molecule Fluorescence Microscopy
Topic: Life Sciences Research
Published: 1/23/2000
Authors: D L. Burden, John J Kasianowicz
Abstract: We describe the use of scanning confocal fluorescence microscopy to probe the structure and temporal dynamics of unsupported planar lipid bilayer membranes. At high fluorescent label concentration, the shape and stability of the membranes are evalua ...

176. Surface stress of tin oxide electrode
Topic: Life Sciences Research
Published: 1/1/2000
Authors: Gintaras Valincius, Vytautas Reipa

177. Thermal Stability of PNA/DNA and DNA/DNA Duplexes by Differential Scanning Calorimetry
Topic: Life Sciences Research
Published: 12/15/1999
Authors: M C. Chakrabarti, Frederick P. Schwarz
Abstract: Thermodynamic quanties describing the hybridizatin reactions for 8mer PNA/DNA duplexes and the corresponding 8mer DNA/DNA duplexes were determined by isothermal titation calorimetry measurements at ambient temperatures. Values of {delta}G^db^ for ...

178. Long-lifetime Lipid Rhenium Metal-ligand Complex for Probing Membrane Dynamics on the Microsecond Timescale
Topic: Life Sciences Research
Published: 12/1/1999
Authors: L. Li, F N Castellano, I Gryczynski, J R Lakowicz

179. Mapping Oxidative DNA Damage and Mechanisms of Repair
Topic: Life Sciences Research
Published: 12/1/1999
Authors: H Rodriguez, T O'connor, S. A. Akman

180. Microsecond time-scale discrimination among polycytidylic acid, polyadenylic acid, and polyuridylic acid as homopolymers or as segments within single RNA molecules
Topic: Life Sciences Research
Published: 12/1/1999
Authors: M Akeson, D Branton, John J Kasianowicz, E Brandin, D W Deamer
Abstract: Single molecules of DNA or RNA can be detected as they are driven through a single alpha-hemolysin channel by an applied electric field. During translocation, nucleotides within the polynucleotide must pass through the channel pore in sequential sin ...
