1. Bark lesions and sensitivity to frost in beech and Norway spruce
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. Samma nyheter eller likadana? Studier av mångfald i svenska TV-nyheter
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. Intrinsic subtypes and prognostic implications in epithelial ovarian cancer
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. A Gill Filament EROD Assay : Development and Application in Environmental Monitoring
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. Microbial Responses to Antibiotics – Stability of Resistance and Extended Potential of Targeting the Folate Synthesis
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
