11. 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 ...

12. 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 ...

13. On-chip CO2 control for microfluidic cell culture
Topic: Medical Devices
Published: 1/1/2011
Authors: Samuel P Forry, Laurie E Locascio
Abstract: Carbon dioxide partial pressure (PCO2) was controlled on-chip by flowing pre-equilibrated aqueous solutions through control channels across the device. Elevated PCO2 (e.g. 0.05 atm) was modulated in neighboring stagnant channels via equilibration th ...

14. Predicting Microstructure Development During Casting of Drug Eluting Coatings
Topic: Medical Devices
Published: 9/19/2010
Authors: David M. Saylor, Jonathan E Guyer, Daniel Wheeler, James A Warren
Abstract: We have devised a novel diffuse interface formulation to model the development of chem- ical and physical inhomogeneities, i.e. microstructure, during the process of casting drug eluting coatings. These inhomogeneities, which depend on the ...

15. 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 ...

16. Standards for Plasma and Serum Protoemics in Early Cancer Detection: A Needs Assessment Report From the NIST-NCI SMART Workshop, August 18-19, 2005
Topic: Medical Devices
Published: 9/1/2006
Authors: Peter E. Dr. Barker, Paul D Wagner, Stephen E Stein, David M Bunk, S Srivastava, Gilbert Omenn
Abstract: The National Institute of Standards and Technology (NIST) and the National Cancer Institute (NCI) co-sponsored a workshop on August 18-19, 2005 to examine needs for reference materials to support biomarker discovery for early cancer detection. Needs ...

17. Static and Dynamic Stability Performance Measurements of the Home Lift, Position and Rehabilitation (HLPR) Chair/Forklift
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7667
Topic: Medical Devices
Published: 3/3/2010
Authors: Joshua Johnson, Roger V Bostelman
Abstract: The Home Lift, Position and Rehabilitation (HLPR) Chair, developed at the National Institute of Standards and Technology (NIST), has unique capabilities and a unique shape as compared to conventional wheelchairs and powered chairs. The evaluation of ...

18. Synthetic Lung Tumor Data Sets for Comparison of Volumetric Algorithms
Topic: Medical Devices
Published: 7/13/2009
Authors: Adele P Peskin, Alden A Dima, Javier Bernal, David E. Gilsinn, Karen Kafadar
Abstract: The change in pulmonary nodules over time is an important indicator of malignant tumors. It is therefore important to be able to measure change in the size of tumors from computed tomography (CT) data taken at different times and on potentially dif ...

19. Testing for the Antiphospholipid Syndrome: Importance of IgA Anti-beta 2-glycoprotein I
Topic: Medical Devices
Published: 12/17/2000
Authors: T.P. Greco, Michael D. Amos, A.M. Conti-Kelly, J.D. Naranjo, J.W. Ijdo

20. 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 ...
