Current understanding of microRNA (miRNA) biology is limited, and antisense oligonucleotide (ASO) inhibition of miRNAs is a powerful technique for their functionalization. To uncover the role of the liver-specific miR-122 in the adult liver, we inhibited it in mice with a 2'-O-methoxyethyl phosphorothioate ASO. miR-122 inhibition in normal mice resulted in(More)
BACKGROUND Effective influenza surveillance requires new methods capable of rapid and inexpensive genomic analysis of evolving viral species for pandemic preparedness, to understand the evolution of circulating viral species, and for vaccine strain selection. We have developed one such approach based on previously described broad-range reverse transcription(More)
Theoretical conformational energy calculations show that large changes in the width of the binding-site cleft in the L-arabinose-binding protein involve only modest changes in the protein internal energy. Solvation energy changes associated with such variations of the cleft width and with protein-ligand interactions are estimated to be significantly larger(More)
The free energy profiles for four organic cations in right-handed single-helix gramicidin A dimers were computed by using umbrella sampling molecular dynamics with CHARMM. Ion-water column translocations were facilitated by using a novel "water-tunnel" approach. The overlapping pieces of free energy profile for adjacent windows were selected from three(More)
Contributions from the behavioral sciences to the design of computer systems have come primarily from psychology, and have focused on individual cognition. In this symposium, we consider the applicability to system design of approaches that focus on social interaction. The participants comprise pairs of researchers engaged in projects that aim to bring(More)
A method is described for calculating the reaction rate in globular proteins of activated processes such as ligand binding or enzymatic catalysis. The method is based on the determination of the probability that the system is in the transition state and of the magnitude of the reactive flux for transition-state systems. An "umbrella sampling" simulation(More)
