    • Fixed-Point-Like Theorems on Subspaces 

      Bich, Philippe; Cornet, Bernard (Hindawi Publishing Corporation, 2004-08-26)
      We prove a fixed-point-like theorem for multivalued mappings defined on the finite Cartesian product of Grassmannian manifolds and convex sets. Our result generalizes two different kinds of theorems: the fixed-point-like ...

    • A note on nonidentification in truncated sampling distribution estimation 

      Barnett, William A.; Seck, Ousmane (Economics Bulletin, 2010-06-19)
      Theoretical constraints on economic model parameters often are in the form of inequality restrictions. For example, many theoretical results are in the form of monotonicity or nonnegativity restrictions. Inequality constraints ...

      A series of substituted diaryltriazoles was prepared by a solid-phase-synthesis protocol using a modified Wang resin. The copper(I)- or ruthenium(II)-catalyzed 1,3-cycloaddition on the polymer bead allowed a rapid synthesis ...
    • Automated three-component synthesis of a library of γ-lactams 

      Fenster, Erik; Hill, David; Reiser, Oliver; Aubé, Jeffrey (Beilstein-Institut, 2012-10-19)
      A three-component method for the synthesis of γ-lactams from commercially available maleimides, aldehydes, and amines was adapted to parallel library synthesis. Improvements to the chemistry over previous efforts include ...
    • Hydrophobic analogues of rhodamine B and rhodamine 101: potent fluorescent probes of mitochondria in living C. elegans 

      Mottram, Laurie F.; Forbes, Safiyyah; Ackley, Brian D.; Peterson, Blake R. (Beilstein-Institu, 2012-12-11)
      Mitochondria undergo dynamic fusion and fission events that affect the structure and function of these critical energy-producing cellular organelles. Defects in these dynamic processes have been implicated in a wide range ...
    • Synthetic probes for the study of biological function 

      Aubé, Jeffrey (Beilstein-Institut, 2013-01-15)
    • Differential levels of glutamate dehydrogenase 1 (GLUD1) in Balb/c and C57BL/6 mice and the effects of overexpression of the Glud1 gene on glutamate release in striatum 

      Hascup, Kevin N.; Bao, Xiaodong; Hascup, Erin R.; Hui, Dongwei; Xu, Wenhao; Pomerleau, Francois; Huettl, Peter; Michaelis, Mary Lou; Michaelis, Elias K.; Gerhardt, Greg A. (Portland Press Limited, 2011-03-29)
      We have previously shown that overexpression of the Glud1 (glutamate dehydrogenase 1) gene in neurons of C57BL/6 mice results in increased depolarization-induced glutamate release that eventually leads to selective neuronal ...
    • DB-PABP: a database of polyanion-binding proteins 

      Fang, Jianwen; Dong, Yinghua; Slamat-Miller, Nazila; Middaugh, C. Russell (Oxford University Press, 2007-10-04)
      The interactions between polyanions (PAs) and polyanion-binding proteins (PABPs) have been found to play significant roles in many essential biological processes including intracellular organization, transport and protein ...
    • Functional Genomics of Brain Aging and Alzheimer’s Disease: Focus on Selective Neuronal Vulnerability 

      Wang, Xinkun; Michaelis, Mary Lou; Michaelis, Elias K. (Bentham Science, 2010-10-21)
      Pivotal brain functions, such as neurotransmission, cognition, and memory, decline with advancing age and, especially, in neurodegenerative conditions associated with aging, such as Alzheimer’s disease (AD). Yet, deterioration ...
