21. Isolation, Purification, and Full NMR Assignments of cyclopamine from Veratrum californicum
Topic: Drugs/Pharmaceuticals
Published: 6/24/2009
Authors: Daniel W Bearden, John E. Oatis, Pam Brunsfeld, James W. Rushing, Peter D. Moeller, Thomas N. Gallien, George W. Cooper
Abstract: The Hedgehog (Hh) signaling pathway is essential for embryogenesis and tissue homeostasis in the adult. However, it may also induce malignancies in a number of tissues when constitutively activated, and it also may have a role in other forms of nor ...

22. Microfluidic Synthesis of Nano-Liposomal Anesthetics
Topic: Drugs/Pharmaceuticals
Published: 5/12/2013
Authors: Wyatt N Vreeland, Renee R Hood, Eric Kendall, Mariana Junqueira, Julia Finkel, Don L. DeVoe
Abstract: Topical anesthesia has the ability to provide painless application of pain management medications for minor procedures such as venipuncture, particularly in the pediatric population. Liposomes have been proposed as a highly advantageous nanocarrier f ...

23. Microfluidic preparation of liposomes to determine particle size influence on cellular uptake mechanisms
Topic: Drugs/Pharmaceuticals
Published: 10/3/2013
Authors: Wyatt N Vreeland, Abhay U Andar, Renee R Hood, Don L. DeVoe, Peter W Swaan
Abstract: Purpose: This study investigates the cellular uptake and trafficking of liposomes in Caco-2 cells, using vesicles with distinct average diameters ranging from 40 nm-276 nm. Liposomes were prepared by microfluidic hydrodynamic flow focusing, producing ...

24. Microfluidic-Enabled of Liposomes Elucidate Size-Dependent Transdermal Transport
Topic: Drugs/Pharmaceuticals
Published: 3/21/2014
Authors: Wyatt N Vreeland, Renee R Hood, Eric Kendall, Don L. DeVoe, Julia Finkel, Mariana Junqueira, Zenaide Quezado
Abstract: Microfluidic synthesis of small and nearly-monodisperse liposomes is used to investigate the size-dependent passive transdermal transport of nanoscale lipid vesicles. While large liposomes with diameters above 105 nm are found to be excluded from dee ...

25. Modification of tethered bilayers by phospholipid exchange with vesicles
Topic: Drugs/Pharmaceuticals
Published: 2/27/2013
Authors: David J Vanderah, Rima Budvytyte, Mindaugas Mickevicius, Gintaras Valincius, Frank Heinrich
Abstract: Phosphatidylcholine and cholesterol exchange between vesicles and planar tethered bilayer lipid membranes (tBLMs) was demonstrated from electrochemical impedance spectroscopy (EIS), fluorescence microscopy (FM), and neutron reflectometry (NR) data. ...

26. Monte Carlo and dynamics simulations of cdk5 Kinase inhibitor peptides p5 in aqueous solution
Topic: Drugs/Pharmaceuticals
Published: 7/20/2012
Authors: Antonio Cardone, Sergio Hassan, Mary C Brady, Ram D Sriram, Harish C. Pant
Abstract: Protein function depends on shape changes that are triggered by interactions with other molecules. Insights into protein dynamics and interactions enable the understanding of certain pathologies, which may be caused by the deregulation of protein ...

27. Multicomponent Chemical Imaging of Pharmaceutical Solid Dosage Forms with Broadband CARS Microscopy
Topic: Drugs/Pharmaceuticals
Published: 7/15/2013
Authors: Christopher Michael Hartshorn, Marcus T Cicerone, Young Jong Lee, Charles H Camp, John Heddleston, Patrick Marsac, Tim Rhodes, Zhen Liu, Nicole Canfield
Abstract: We compare broadband coherent anti-Stokes Raman scattering (BCARS) microscopy with spontaneous Raman microscopy for quantitative and qualitative assessment of multicomponent pharmaceuticals. Indomethacin was used as a model active pharmaceutical ingr ...

30. Predictive Gold Nanocluster Formation Controlled by Metal-Ligand Complexes
Topic: Drugs/Pharmaceuticals
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 ...
