41. Measuring Stem Cell Dimensionality in Tissue Scaffolds
Topic: Bioscience & Health
Published: 4/1/2014
Authors: Carl George Simon Jr., Sapun Parekh, Christopher K. Tison, Girish Kumar, Tanya M. Farooque, Charles H Camp
Abstract: Many 3D scaffold systems have evolved for tissue engineering, drug screening and in vitro tissue models. However, it is not clear which scaffolds provide a 3D cell niche and there is no clear way to measure cell niche dimensionality. Advances in 3D ...

42. Certification of Total Arsenic in Blood and Urine Standard Reference Materials by Radiochemical Neutron Activation Analysis and Inductively Coupled Plasma Mass Spectrometry
Topic: Bioscience & Health
Published: 3/1/2014
Authors: Rick L Paul, William C Davis, Karen E Murphy, Colleen E Bryan, Lee Lijian Yu, William F Guthrie, Dennis D Leber, Thomas W Vetter
Abstract: A newly developed procedure for determination of arsenic by radiochemical neutron activation analysis was used to measure arsenic in SRM 955c Toxic Elements in Caprine Blood and SRM 2668 Toxic Elements in Frozen Human Urine for the purpose of providi ...

43. Assessing Vitamin D Status: Time for a Rethink?
Topic: Bioscience & Health
Published: 2/19/2014
Authors: Karen W Phinney, Graham D. Carter

44. Why human genome sequencing platforms differ: Integrating sequencing datasets to understand biases and form consensus variant calls
Topic: Bioscience & Health
Published: 2/16/2014
Authors: Justin M Zook, Brad Chapman, Winston Hide, Marc L Salit
Abstract: Hundreds of thousands of differences exist between human whole genome variant calls from different sequencing platforms and variant calling pipelines, but the reasons for these differences are poorly understood. Well-characterized whole genome Refer ...

45. Designing High-Performance PbS and PbSe Nanocrystal Electronic Devices through Stepwise, Post-Synthesis, Colloidal Atomic Layer Deposition
Topic: Bioscience & Health
Published: 2/6/2014
Authors: Soong Ju Oh, Nathaniel E. Berry, Hi-Hyuk Choi, E. Ashley Gaulding, Hangfei Lin, Taejong Paik, Benjamin T. Diroll, Shinichiro Muramoto, Murray B. Christopher, Cherie R. Kagan
Abstract: We report a facile, solution based, post synthetic colloidal atomic layer deposition (PS-cALD) process to engineer the surface stoichiometry and therefore electronic properties of lead chalcogenide nanocrystal (NC) thin films. Using the stepwise and ...

46. CPTAC Studies 1 and 5: dissecting variability in multi-site LC-MS/MS proteomics through quality metrics and robust hierarchical multivariate statistics
Topic: Bioscience & Health
Published: 2/4/2014
Authors: Stephen E Stein, David M Bunk, Xia Wang, Matthew Chambers, Lorenzo J Vega-Montoto, David L. Tabb
Abstract: Shotgun proteomics experiments integrate a complex sequence of processes, any of which can introduce variability. Quality metrics computed from LC-MS/MS data have relied upon identifying MS/MS scans, but a new mode for the QuaMeter software produces ...

47. Influence of tissue, age, and environmental quality on global levels of genomic methylation in the American alligator (Alligator mississippiensis)
Topic: Bioscience & Health
Published: 1/7/2014
Authors: Benjamin B Parrott, John A Bowden, Satomi Kohno, Jessica A Cloy-McCoy, Jacqueline T Bangma, Thomas R Rainwater, Phillip M Wilkinson, John R Kucklick, Louis J Guillette
Abstract: Epigenetic modifications are key mediators of the interactions between the environment and an organism‰s genome. DNA methylation represents the best-studied epigenetic modification to date and is known to play key roles in regulating transcriptional ...

48. Tunable electrical conductivity in metal-organic framework thin film devices
Topic: Bioscience & Health
Published: 1/3/2014
Authors: Albert A. Talin, Andrea Centrone, Alexandra C. Ford, Michael E Foster, Vitalie Stavila, Paul M Haney, Robert Adam Kinney, Veronika A Szalai, Farid El Gabaly, Heayoung Yoon, Francois Leonard, Mark Allendorf
Abstract: We report a strategy for realizing tunable electrical conductivity in MOFs in which the nanopores are infiltrated with redox-active, conjugated guest molecules. This approach is demonstrated using thin-film devices of the MOF Cu3(BTC)2 (also known as ...

49. Reconstitution of cholesterol-dependent vaginolysin into tethered phospholipid bilayers: implications for bioanalysis
Topic: Bioscience & Health
Published: 12/13/2013
Author: David J. Vanderah

50. Airbrushed Nanofiber Scaffolds Support Bone Marrow Stromal Cell Differentiation
Topic: Bioscience & Health
Published: 11/1/2013
Authors: Carl George Simon Jr., Wojtek J Tutak, Sumona Sarkar, Tanya M. Farooque, Jyotsnendu J. Giri, Dongbo Wang, Sheng Lin-Gibson, Joachim Kohn, Durgadas Bolikal
Abstract: Nanofiber scaffolds are effective for tissue engineering since they emulate the fibrous nanostructure of native extracellular matrix (ECM). Although electrospinning has been the most common approach for fabricating nanofiber scaffolds, airbrushi ...
