  1. 1. Bark lesions and sensitivity to frost in beech and Norway spruce

    Författare :Anna Maria Jönsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Picea abies; Multiple stress; Mineral nutrient balance; Liming; Lichen indices; Fagus sylvatica; Cryptococcus fagisuga; Excess nitrogen; Vitality fertilization; Plant ecology; Växtekologi;

    Sammanfattning : Strong temperature fluctuations and pathogen attacks can cause bark lesions, visible signs of wounds in the phloem and cambium. Pathogenic insects and fungi are able to invade lesions that have not healed, further increasing the damage. LÄS MER

  2. 2. Samma nyheter eller likadana? Studier av mångfald i svenska TV-nyheter

    Författare :Anna Maria Jönsson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mångfald; tv-nyheter; Aktuellt; Rapport; Nyheterna; geografi; ämne; aktörer; nyhetshändelser; Nyhetsprogram i TV; Media and communication studies;

    Sammanfattning : Avhandlingen analyserar mångfalden i svenska tv-nyheter under perioden 1980-2000 med särskilt fokus på 1990-talet. Frågorna som besvaras är hur mångfalden i Rapport, Aktuellt och TV4:s Nyheterna ser ut, om och i så fall hur den har förändrats över tid samt hur olika faktorer påverkar mångfalden. LÄS MER

  3. 3. Intrinsic subtypes and prognostic implications in epithelial ovarian cancer

    Författare :Jenny-Maria Jönsson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovarian cancer; gene expression profiling; Lynch syndrome; targeted deep sequencing; chromatin remodeling; molecular subtypes; endocrine receptors; prognostic factors; tumor heterogeneity;

    Sammanfattning : Ovarian cancer is the seventh most common cancer in women globally, with approximately 240,000 new cases annually. Although a rare disease, it is the most lethal gynecologic malignancy. Unspecific symptoms result in late diagnosis and a generally poor prognosis. LÄS MER

  4. 4. A Gill Filament EROD Assay : Development and Application in Environmental Monitoring

    Författare :Maria Jönsson; Ingvar Brandt; Björn Brunström; Kristian Ingebrigtsen; Håkan Olsén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; aquatic; benzo[a]pyrene; biomarker; CYP1A; environmental monitoring; EROD; fish; gill; indigo; PCB; Biologi; Biology; Biologi;

    Sammanfattning : A gill filament-based assay for the cytochrome P450 1A (CYP1A)-catalysed activity ethoxyresorufin O-deethylase (EROD) was developed in rainbow trout (Oncorhynchus mykiss) and applied to Atlantic salmon (Salmo salar), Arctic charr (Salvelinus alpinus), Atlantic cod (Gadus morhua), saithe (Pollachius virens), and spotted wolffish (Anarhichas minor). Exposure to waterborne β-naphthoflavone (βNF; 10-6 M) induced branchial EROD activity in all species but the spotted wolffish. LÄS MER

  5. 5. Microbial Responses to Antibiotics – Stability of Resistance and Extended Potential of Targeting the Folate Synthesis

    Författare :Maria Jönsson; Göte Swedberg; Steven Meshnick; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; sulfonamide resistance; macrolide; commensal flora; substrate channeling; folate synthesis; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Sammanfattning : Resistance to antimicrobials is an increasing problem in the world of today, and develops faster than man can counter. It is therefore of importance to study metabolic pathways in order to develop new antibiotics, but also to understand how resistance spreads and stabilizes in microbial populations. LÄS MER
