  4. 4. Conformationally Constrained Oligonucleotides for RNA Targeting

    Författare :Qing Li; Jyoti Chattopadhyaya; Li-He Zhang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conformationally constrained nucleoside; antisense oligonucleotide; RNA affinity; nuclease stability; RNase H; RNA degradation; Chemistry with specialization in Bioorganic Chemistry; Kemi med inriktning mot bioorganisk kemi;

    Sammanfattning : A short oligonucleotide sequence as in a single-stranded antisense oligo nucleotides (AON) or in double-stranded small interfering RNAs (siRNA) can modulate the gene expression by targeting against the cellular mRNA, which can be potentially exploited for therapeutic purposes in the treatment of different diseases. In order to improve the efficacy of oligonucleotide-based drugs, the problem of target affinity, nuclease stability and delivery needs to be addressed. LÄS MER

  5. 5. On the returns of trend-following trading strategies

    Författare :Christian Lundström; Tomas Sjögren; Jussi Nikkinen; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bootstrap; Commodity Trading Advisor funds; Contraction-Expansion principle; Crude oil futures; Futures trading; Opening Range Breakout strategies; S P 500 futures; Technical analysis; Time series momentum; Time-varying market inefficiency; nationalekonomi; Economics;

    Sammanfattning : Paper [I] tests the success rate of trades and the returns of the Opening Range Breakout (ORB) strategy. A trader that trades on the ORB strategy seeks to identify large intraday price movements and trades only when the price moves beyond some predetermined threshold. LÄS MER
