    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the popularity of wireless communications in the last two decades, data traffic is exponentially increasing and requests high speed transmission. However, the resources, in particular, spectrum and energy, are limited. READ MORE

  5. 3. Conformationally Constrained Oligonucleotides for RNA Targeting

    Author : Qing Li; Jyoti Chattopadhyaya; Li-He Zhang; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Studies on antioxidant and lipid lowering effects on human microcirculation

    Author : Qing Lu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Microcirculation; oxidative stress; antioxidant; smoking. hypercholesterolemia; diabetes; vitamin C; Nacetylcysteine; lipid lowering; capillary blood flow velocity; post reactive hyperemia; endothelial function.;

    Abstract : In previous work from this laboratory, vital microscopy was successfully used to study rnicrocirculatcry effects of hypercholesterolemia in a rabbit model. Hypercholesterolemia caused a dramatic depression of the blood flow velocity in the conjunctiva microvessels of the rabbits. READ MORE
