متن کاملFocusing on RISC assembly in mammalian cells.
RISC (RNA-induced silencing complex) is a central protein complex in RNAi, into which a siRNA strand is assembled to become effective in gene silencing. By using an in vitro RNAi reaction based on Drosophila embryo extract, an asymmetric model was recently proposed for RISC assembly of siRNA strands, suggesting that the strand that is more loosely paired at its 5' end is selectively assembled i...
متن کاملAdvertisements Evaluation Focusing on Human Face
Given the importance of advertising and the massive expenditures on it, evaluating its effectiveness is one of the key questions in marketing. Also endorser as the most commonly used communication tool, allocates a large portion of advertising costs and its use is still under development. In this project, we use Communicational and Observational approaches to explore the impact of utilizing ‘hu...
متن کاملFocusing on unpolymerized actin
~ scinating feature of cell locomotion is that net actin polymerization and depolymerization occur simultaneously at different locations in the cytoplasm, while the total concentration of polymerized actin remains roughly constant. Net polymerization occurs primarily at the cell front and net depolymerization occurs, depending on cell type, throughout or at the rear of the lamella (Wang, 1985; ...
متن کاملFocusing on Contraction
Focusing [1] is a proof-theoretic device to structure proof search in the sequent calculus: it provides a normal form to cut-free proofs in which the application of invertible and non-invertible inference rules is structured in two separate and disjoint phases. It is commonly believed that every “reasonable” sequent calculus has a natural focused version. Although stemming from proof-search con...
