  2. 1. The effects of crayfish on interactions in freshwater benthic communities

    Author : Per Nyström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exotic species; trophic cascades; omnivory; crayfish; Trophic interactions; freshwater; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Abstract : This thesis examines how freshwater crayfish affect community interactions in benthic food webs. I have mainly studied the influence of the introduced signal crayfish (Pacifastacus leniusculus) on littoral communities, but also the influence of the native noble crayfish (Astacus astacus).

  4. 2. Microgels as Carriers for Antimicrobial Peptides : Surface-bound microgels, and factors affecting peptide interactions

    Author : Lina Nyström; Martin Malmsten; Per Hansson; L. Andrew Lyon; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial peptides; Biomaterial coating; Drug delivery; Host defence peptides; Microgels; pH-responsive; Surface-bound; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    Abstract : With a growing number of multi-resistant bacteria against conventional antibiotics, there is an urgent need to identify new antimicrobial therapeutics. One example that has gained considerable interest is antimicrobial peptides (AMPs). READ MORE

  5. 3. Stromal collagens in colorectal cancer and in colorectal liver metastases : tumour biological implications and a source for novel tumour markers

    Author : Hanna Nyström; Malin Sund; Peter Naredi; Per Sandström; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colorectal cancer; colorectal liver metastases; tumour marker; stroma; type IV collagen; metastatic growth pattern; kirurgi; Surgery;

    Abstract : Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality. About 50 % of patients with CRC will develop subsequent liver metastases (CLM). The survival for untreated CLM is only a few months and liver resection provides the only chance for a lasting cure. READ MORE

  6. 4. Early events in disease associated protein misfolding

    Author : Sofie Nyström; Per Hammarström; Marcus Fändrich; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : The scope of this thesis is to unravel some of the mysteries concerning events takingplace early in the amyloid cascade. In vitro studies of early misfolded states ofamyloidogenic proteins are important since the use of recombinant proteins allow us to monitor slight changes in environmental conditions as well as in amino acid composition and thereby illuminate the problem at near atomic resolution.

  7. 5. Clinical and immunological aspects of IgG subclass deficiency : Predictors for the need of immunoglobulin replacement therapy

    Author : Per Wågström; Charlotte Dahle; Sofia N. Nyström; Åsa Nilsdotter-Augustinsson; Mats Nilsson; Ola Winqvist; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunoglobulin G subclass deficiency; inflammation; lymphocytes; fatigue; co-morbidity; immunoglobulin G replacement therapy;

    Abstract : Background: Predominantly antibody deficiencies (PAD) are inborn errors of immunity, and associate with increased susceptibility to infections. Life-long immunoglobulin replacement therapy (IgRT) is introduced based on Ig-levels and the frequencies and severity of infections. READ MORE
