Thermodynamics of Enzyme Catalyzed Reactions: Part 7 - 2007 Update

October 25, 2007
Author(s)
Robert N. Goldberg, Yadu D. Tewari, Talapady N. Bhat
This review serves to update previously published evaluations of equilibrium constants and enthalpy changes for enzyme catalyzed reactions. For each reaction the following information is given: the reference for the data; the reaction studied; the name of

Covalent Attachment of Photoluminescent Silicon Nanoparticles to Streptavidin

September 11, 2007
Author(s)
Jonghoon Choi, Peter Niarhos, Nam S. Wang, Vytas Reipa
We have covalently attached multiple fluorescent silicon nanocrystals (SNs) to streptavidin molecule. Selective conjugation of SNs to a target protein is accomplished using sequential silicon surface termination chemistry. In the first step, freshly

Characterization of degradation mechanisms in neural recording electrodes

August 1, 2007
Author(s)
Jennifer Anton, Stephanie A. Hooker
Understanding the nature of specific neural activity is essential to the progression of research in the field of brain disorders and diseases, as well as neuroprosthetics. Microelectrodes are the primary measurement devices used to transduce neural

Concordance Study Between the AmpFlSTR((R)) MiniFiler(TM) PCR Amplification Kit and Conventional STR Typing Kits

July 25, 2007
Author(s)
Carolyn R. Steffen, Margaret C. Kline, Julio J. Mulero, Robert E. Lagace, Chien-Wei Chang, Lori K. Hennessy, John M. Butler
The AmpFlSTR MiniFiler PCR Amplification kit developed by Applied Biosystems enables size reduction on eight of the larger short tandem repeat (STR) loci amplified in the Identifiler kit, which will aid recovery of information from highly degraded DNA

Recent Developments of the HLPR Chair

June 15, 2007
Author(s)
Roger V. Bostelman, James S. Albus, Tommy Chang
The Home Lift, Position and Rehabilitation (HLPR) Chair, developed at the National Institute of Standards and Technology (NIST) within the Intelligent Systems Division (ISD) from 2005 to 2006, is currently being evaluated for static stability using

Cholesterol/Phospholipid Interactions in Hybrid Bilayer Membranes

May 25, 2007
Author(s)
Dustin Levy, Kimberly Briggman
The interactions between cholesterol and saturated phospholipids in hybrid bilayer membranes (HBMs) were investigated using the interface-sensitive technique of vibrational sum frequency spectroscopy (VSFS). The unique sensitivity of VSFS to order/disorder

A new model of pulse oximetry: Two-dimensional pulsation

March 14, 2007
Author(s)
Shao Yang, Paul B. Batchelder, Dena M. Raley
We developed a two-dimensional pulsation model of pulse oximetry. Instead of a one-dimensional single layer as in the conventional theory, the arteries pulsate in two dimensions taking into account the effect of probing light that does not pass through the
