  1. 1. A multivariate approach to computational molecular biology

    Författare :Fredrik Pettersson; Michael Sjöström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PLS; PCA; biomarker; Drosophila; SNP; linkage; disequilibrium; bioinformatics; computational; molecular; biology; genomics; microarray; SELDI; proteomics; Bioinformatics; Bioinformatik;

    Sammanfattning : This thesis describes the application of multivariate methods in analyses of genomic DNA sequences, gene expression and protein synthesis, which represent each of the steps in the central dogma of biology. The recent finalisation of large sequencing projects has given us a definable core of genetic data and large-scale methods for the dynamic quantification of gene expression and protein synthesis.

    Sammanfattning : En sjukdom kan många gånger härledas till en kaskadereaktion mellan proteiner, co-faktorer och substrat. Denna kaskadreaktion blir många gånger målet för att behandla sjukdomen med läkemedel. För att designa nya läkemedelsmoleyler används vanligen datorbaserade verktyg. LÄS MER

  4. 3. Prediction of wood species and pulp brightness from roundwood measurements

    Författare :David Nilsson; Ulf Edlund; Michael Sjöström; Olav Kvalheim; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Design of Experiments; ISO brightness; Multivariate Image Analysis; Multivariate Modelling; NIR spectroscopy; Norway spruce; PCA; PLS; Roundwood; Scots pine; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis presents a number of studies, where a multivariate approach was taken to construct models that predict wood species and thermo mechanical pulp brightness from roundwood of Norway spruce and Scots pine. The first and second studies produced multivariate prediction models for wood species from the bark of spruce and pine. LÄS MER

  5. 4. Physico-chemical characteristics and quantitative structure-activity relationships of PCBs

    Författare :Patrik Andersson; Stephen Safe; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polychlorinated biphenyls; PCBs; physico-chemical properties; statistical design; multivariate; PCA; PLS; biomagnification; BMF; bioassay; CYP1A; SAR; QSAR; REPs; risk assessment; Chemistry; Kemi; Chemistry; Kemi;

    Sammanfattning : The polychlorinated biphenyls (PCBs) comprise a group of 209 congeners varying in the number of chlorine atoms and substitution patterns. These compounds tend to be biomagnified in foodwebs and have been shown to induce an array of effects in exposed organisms. LÄS MER

  7. 5. Multivariate methods in tablet formulation

    Författare :Jon Gabrielsson; Michael Sjöström; Svante Wold; Torbjörn Lundstedt; Marc Brown; Umeå universitet; []
