1. NIST System for Measuring the Directivity Index of Hearing Aids under Simulated Real-Ear Conditions
Series: Journal of Research (NIST JRES)
Report Number: 118.005
Topic: Medical Devices
Published: 1/24/2013
Author: Randall P Wagner
Abstract: The directivity index is a parameter that is commonly used to characterize the performance of directional hearing aids, and is determined from the measured directional response. Since this response is different for a hearing aid worn on a person ...

2. The Effects of Diffusion on an Exonuclease/Nanopore-Based DNA Sequencing Engine
Topic: Medical Devices
Published: 12/7/2012
Authors: Joseph E Reiner, Joseph William Robertson, Arvind Kumar Balijepalli, Daniel L Burden, Bryon S. Drown, John J Kasianowicz
Abstract: The ability to electronically detect and characterize individual polynucleotides as they are driven through a single protein ion channel may eventually prove useful for rapidly sequencing DNA (base-by-base) in a ticker tape-like fashion. More recent ...

3. GENERATING CELL CO-CULTURES BY RAPID CELL ADHESION ON OPPOSITE SIDES OF POLYESTER MEMBRANES
Topic: Medical Devices
Published: 10/28/2012
Authors: Conni Hanke, Petra S. Dittrich, Darwin R Reyes-Hernandez
Abstract: A cell co-culture was generated on opposite sides of a permeable polyester membrane (PET) membrane by combining dielectrophoretic (DEP) and electrostatic forces to hold cells against gravity in a multilayer microfluidic device (Figure 1). HepG2 cell ...

4. Fabrication of Microelectrodes on Polyester Membranes for Dielectrophoretic Cell Capture
Topic: Medical Devices
Published: 6/18/2012
Authors: Conni Hanke, Petra S. Dittrich, Darwin R Reyes-Hernandez
Abstract: We present a new system for cell capturing on permeable polyester (PET) membranes using dielectrophoretic forces. For the first time gold microelectrodes were fabricated on PET membranes using conventional photolithographic techniques. Their charac ...

5. An instrumented bioreactor for mechanical stimulation and real-time, nondestructive evaluation of engineered cartilage tissue
Topic: Medical Devices
Published: 6/1/2012
Authors: Jenni R. Popp, Justine Roberts, Douglas V Gallagher, Kristi S Anseth, Stephanie Bryant, Timothy P Quinn
Abstract: Mechanical stimulation is essential for chondrocyte metabolism and cartilage matrix deposition. In vitro, mechanical stimulation is accomplished via culture in a bioreactor. Traditional methods for evaluating the developing tissue are destructive ...

6. Uncertainty in RECIST as a measure of volume for lung nodules and liver malignoma
Topic: Medical Devices
Published: 4/27/2012
Authors: Zachary H Levine, Adam L Pintar, John G Hagedorn, Charles D. Fenimore, Claus P. Heussel
Abstract: The authors investigate the extent to which the RESPONSE Evaluation Criateria in Solid Tumors (RECIST) can predict tumor volumes and changes in volume using clinical data. The data presented are a reanalysis of data acquired in other studies, includ ...

7. Predictive Gold Nanocluster Formation Controlled by Metal-Ligand Complexes
Topic: Medical Devices
Published: 1/9/2012
Authors: John M. Pettibone, Jeffrey W Hudgens
Abstract: The formation of ligand-protected transition metal nanoclusters in size-selective syntheses is driven by the inherent properties of the protecting ligands. We have previously reported the selective, monodisperse product formation of phosphine protect ...

8. Morphological Changes Driven by Nanofibrous Scaffolds Induce Marrow Stromal Cell Osteogenesis
Topic: Medical Devices
Published: 10/11/2011
Authors: Carl GEORGE Simon Jr, Kaushik Chatterjee, Christopher K. Tison, Girish Kumar, Patrick S Pine, Marc L Salit, Jennifer H McDaniel, Marian F Young
Abstract: Cells are sensitive to tissue scaffold architecture and these cell-material interactions drive cell functions critical in tissue regeneration. Results presented here demonstrate that nanofiber scaffolds force primary human bone marrow stromal cells ...

9. Hybrid Cell Adhesive Material for Instant Dielectrophoretic Cell Trapping and Long Term Cell Function Assessment
Topic: Medical Devices
Published: 8/16/2011
Authors: Darwin R Reyes-Hernandez, Jennifer S. Hong, John T Elliott, Michael Gaitan
Abstract: We present the development and evaluation of an engineered hybrid cell adhesive surface for instant dielectrophoretic trapping and patterning of cells in a microfluidic device. This work demonstrates that a hybrid cell adhesive material (hCAM) prepar ...

10. The Lung Image Database Consortium (LIDC) and Image Database Resource Initiative (IDRI): A Completed Reference Database of Lung Nodules on CT Scans
Topic: Medical Devices
Published: 1/28/2011
Authors: Charles D. Fenimore, Samuel Armato, Denise Aberle, Matthew Brown, Claudia Henschke, Michael McNitt-Gray, Heber MacMahon, Geoffrey McLennan, Charles R Meyer, Anthony P Reeves, David F Yankelevitz
Abstract: The development of computer-aided diagnostic (CAD) methods for lung nodule detection, classification, and quantitative assessment can be facilitated through a well-characterized repository of computed tomography scans. The Lung Image Database Consor ...
