31. A mini-review: Cell response to microscale, nanoscale, and hierarchical patterning of surface structure
Topic: Bioscience & Health
Published: 9/12/2014
Authors: Carl George Simon Jr., Geunhyung Kim, HoJun Jeon
Abstract: Cellular behavior can be influenced by the chemical and physical surface characteristics of biomedical substrates. To understand the relationships between various topographical surface patterns and cellular activities, various types of pattern mo ...

32. Rbm24a and Rbm24b are required for normal somitogenesis
Topic: Bioscience & Health
Published: 8/29/2014
Author: Samantha D Maragh
Abstract: We recently demonstrated that the gene encoding the RNA binding motif protein 24 (Rbm24)¬¬ is expressed during mouse cardiogenesis, and determined the developmental requirement for its zebrafish homologs Rbm24a and Rbm24b during cardiac developme ...

33. Multiscale Correlative Measurements of Nanoparticles in Cells
Topic: Bioscience & Health
Published: 8/26/2014
Authors: Aric Warner Sanders, Kavita M Jeerage, Cindi Schwartz, Alexandra E Curtin, Ann Chiaramonti Chiaramonti Debay
Abstract: Nanoparticles are emerging as invaluable tools in disease diagnosis, disease treatment and imaging contrast enhancement agents. The interactions of nanoparticles with host organisms are complex and affect biological systems over length scales that va ...

34. Performance Benchmarking and Intensity Calibration of a Widefield Fluorescence Microscope Using Fluorescent Glass
Topic: Bioscience & Health
Published: 8/11/2014
Authors: Michael W Halter, Elianna Bier, Paul C DeRose, Gregory A Cooksey, Steven J Choquette, Anne L Plant, John T Elliott
Abstract: Widefield fluorescence microscopy is a highly used tool for visually assessing biological samples and for quantifying cell responses. Despite its widespread use in high content analysis and other screening applications, few published methods exist f ...

35. Viscosity Measurements of DNA Solutions with and without Condensing Agents
Topic: Bioscience & Health
Published: 7/7/2014
Authors: Arno R Laesecke, Jessica Lynne Burger
Abstract: Aqueous DNA solutions at three concentrations were studied as model sputum by viscosity measurements at ambient pressure. Initial measurements at 25 {degree}C, 37.78 {degree}C, and 50 {degree}C indicated a viscosity increase toward 50 {degree}C. Th ...

36. Hot carriers in epitaxial graphene sheets with and without hydrogen intercalation: role of substrate coupling
Topic: Bioscience & Health
Published: 7/1/2014
Authors: Randolph E Elmquist, Chiashain Chuang, Yanfei Yang, Lung-I Huang, Chi-Te Liang
Abstract: The development of graphene electronic devices produced by industry will rely on efficient control of heat transfer from the graphene sheet to its environment. In nanoscale devices, heat is one of the major obstacles to the operation of such devices ...

37. Tandem Mass Spectral Libraries of Peptides in Digests of Individual Proteins: Human Serum Albumin
Topic: Bioscience & Health
Published: 6/2/2014
Authors: Qian Dong, Xinjian Yan, Lisa Ervin Kilpatrick, Yuxue Liang, Yuri Alexander Mirokhin, Jeri S Roth, Stephen E Stein
Abstract: This work presents a method for creating a mass spectral library containing tandem spectra identifiable peptide ions in the tryptic digestion of a single protein. Human serum albumin (HSA) was selected for this purpose owing to its ubiquity and h ...

38. Topological physics with light
Topic: Bioscience & Health
Published: 5/1/2014
Authors: Jacob M Taylor, Mohammad Hafezi
Abstract: Electrons in a so-called topological insulator circulate around the material‰s boundary without ever straying into the bulk. Uncharged photons can be induced to carry out similar behavior.

39. Measuring Organelle Shape in 3D in Stem Cells Cultured on Nanofiber Scaffolds
Topic: Bioscience & Health
Published: 4/19/2014
Authors: Carl George Simon Jr., Peter Bajcsy, Wojtek J Tutak, Jyotsnendu J. Giri
Abstract: Previous work has demonstrated that culture of osteoprogenitor cells on nanofiber scaffolds can potentiate osteogenic differentiation [1-4]. Culture of cells in nanofiber scaffolds causes changes to cell morphology, suggesting that morphological ...

40. Roles of Nanofiber Structure and Chemistry in Directing Stem Cell Morphology, Differentiation and Gene Expression
Topic: Bioscience & Health
Published: 4/19/2014
Authors: Sumona Sarkar, Bryan A. Baker, Desu Chen, Wolfgang Losert, Carl George Simon Jr., Joy P Dunkers
Abstract: Nanofiber technology has emerged as a promising tool to recapitulate the native extracellular matrix (ECM) environment for tissue engineering and regenerative medicine strategies. Cell-material interactions in the nanofiber system are largely de ...
