    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor network; traffic analysis; network optimization; anomaly detection; Computer and systems science; Data- och systemvetenskap;

    Abstract : Wireless sensor network (WSN) has emerged as a promising technology thanks to the recent advances in electronics, networking, and information processing. A wide range of WSN applications have been proposed such as habitat monitoring, environmental observations and forecasting systems, health monitoring, etc. READ MORE

  4. 2. Basal lamina genes affected in leiomyomatosis and congenital muscular dystrophy : structure and mutation analyses of the collagen COL4A6 and laminin LAMA2 genes

    Author : Xu Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Basal laminae (basement membranes) are flexible thin sheets of specialized extracellular matrix separating organ cells from the underlying or surrounding connective tissues. They are found beneath epithelial and endothelial cells amd surrounding different cells, such as muscle fibers and nerves. READ MORE

  5. 3. Role of thioredoxin system in cell death caused by toxic compounds

    Author : Xu Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Thioredoxin systems, comprising Trx, TrxR and NADPH, are one of the major disulfide reductase systems, which is crucial in maintaining cellular redox balance in mammalian cells. TrxR is a selenoprotein with a Sec residue in its C-terminal active site. READ MORE

  6. 4. Humoral and cellular immune responses to proteins encoded by the hepatitis C virus

    Author : Zhu-Xu Zhang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HCV; genotype; antibody; IFN-alpha; MHC; haplotype; ScFv; peptide; T cell;

    Abstract : The hepatitis C virus (HCV) was the first described human pathogen of the hepaciviruses, a new genus within the flaviviridae family. A characteristic feature of HCV is that it has a high genetic heterogenecity. It is believed that the immune response is of vital importance to prevent, control, and to eradicate HCV infections.
