21. Probing the intracellular glutathione redox potential using in-cell NMR spectroscopy
Topic: Bioscience & Health
Published: 1/2/2014
Authors: Steve Y. Rhieu, Aaron A Urbas, Daniel W Bearden, John P Marino, Vytautas Reipa, Katrice A Lippa
Abstract: Non-invasive and real-time analysis of cellular redox processes has been greatly hampered by lack of suitable measurement techniques. Here we describe an in-cell nuclear magnetic resonance (NMR)-based method for measuring the intracellular glutathion ...

23. Effect of interdome spacing on the resonance properties of plasmonic nanodome arrays for label-free optical sensing
Topic: Bioscience & Health
Published: 11/11/2013
Authors: Charles J. Choi, Stephen Semancik
Abstract: In this paper, we report on experimental and theoretical studies of investigating how the structural properties of plasmonic nanodome array devices determine its optical properties and sensing performance. We focused on examining the effect of the i ...

24. Fabrication and Characterization of a Dual-mode SPR/SERS Sensor Based on Plasmonic Nanodome Arrays
Topic: Bioscience & Health
Published: 11/3/2013
Authors: Charles J. Choi, Stephen Semancik
Abstract: This work describes a label-free, optical sensor system fabricated on a flexible plastic film with dual detection modalities: surface-enhanced Raman scattering (SERS) for specific chemical identification and localized surface plasmon resonance (LSPR) ...

25. 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 (Jyotsnendu) 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 ...

26. Determining carbapenemase activity with 18O labeling and targeted mass spectrometry
Topic: Bioscience & Health
Published: 10/16/2013
Authors: Meiyao Wang, Yang Shen, Illarion V Turko, Daniel Nelson, Shuwei Li
Abstract: Carbapenems are broad spectrum antibiotics considered as last resort drugs to treat bacterial infections. Carbapenem-hydrolyzing β-lactamases (also called carbapenemases), however, can confer bacterial resistance and represent a serious health t ...

27. Comprehensive analysis of protein digestion using six trypsins reveals the origin of trypsin as a significant source of variability in proteomics
Topic: Bioscience & Health
Published: 10/11/2013
Authors: Stephen E Stein, Paul A Rudnick, Scott J Walmsley, Qian Dong, Alexey I Nesvizhskii, Yuxue Liang
Abstract: Trypsin is an endoprotease commonly used for sample preparation in proteomics experiments. Importantly, protein digestion is dependent on multiple factors, including the trypsin origin and digestion conditions. In-depth characterization of tryp ...

28. TLR stimulation initiates a CD39-based autoregulatory mechanism that limits macrophage inflammatory responses
Topic: Bioscience & Health
Published: 9/12/2013
Authors: John P Marino, Katharine Therese Briggs, Heather Cohen, Katya Ravid, Simon C. Robson, David M. Mosser
Abstract: Sepsis is a highly fatal disease caused by an initial hyperinflammatory response followed by a state of profound immunosuppression. Although it is well appreciated that the initial production of proinflammatory cytokines by macrophages accompanies th ...

30. Functionalization-Dependent Induction of Cellular Survival Pathways by CdSe Quantum Dots in Primary Normal Human Bronchial Epithelial Cells
Topic: Bioscience & Health
Published: 9/5/2013
Authors: Amber Nagy, Jennifer A Hollingsworth, Bin Hu, Andrea Steinbruck, Peter C. Stark, Cristina Rios Valdez, Momchilo Vuyisich, Michael H. Stewart, Donald H Atha, Bryant C Nelson, Rashi Iyer
Abstract: Quantum dots (QDs) are semiconductor nanocrystals exhibiting unique optical properties which can be exploited for many practical applications ranging from photovoltaics to biomedical imaging and drug delivery. They are increasingly manufactured in la ...
