    Keywords : HPV; EBV; HSV-1; Oral Squamous Cell Carcinoma; Leukoplakia; apopto-sis; cell cycle regulation; intermediate filament proteins.; Medicinsk genetik; Medical Genetics;

    Abstract : Background. Head and neck cancers (HNC) are among the most common malignancies worldwide, and about 90–92% of oral neoplasias are oral squamous cell carcinomas (OSCC). Alcohol and tobacco consumption have been recognized as the main risk factors for OSCC development. READ MORE

  4. 2. External Mycelia of Mycorrhizal Fungi - responses to elevated N in forest ecosystems

    Author : Lars Ola Nilsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ericoid; arbuscular; mycorrhiza; nitrogen; deposition; fertilisation; nitrate leaching; retention; field; forest; Quercus; deciduous; Plant ecology; Växtekologi; mykologi; virologi; bakteriologi; mycology; Microbiology; External mycelia; ectomycorrhiza; Mikrobiologi; bacteriology; virology;

    Abstract : Most plants live in symbiosis with mycorrhizal fungi. Mycorrhizal roots constitute the interface between the plant and the soil, and almost every fine root of forest trees in nitrogen-limited boreal and temperate forests is colonised by ectomycorrhizal (EM) fungi. READ MORE

  5. 3. Mineralisation rates of natural organic matter in surface sediments affected by physical forces

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sediment; Organic matter mineralisation; Organic matter degradation; Redox; Electron acceptor; Resuspension; Advective pore water flow; Other chemistry; Övrig kemi;

    Abstract : Nedbrytning av organiskt material är en nyckelfaktor som påverkar omvandlingar av de många grundämnen som utgör eller är associerade till just organiskt material. En stor del av nedbrytningen av akvatiskt organiskt material (OM) sker i gränsskiktet mellan sediment och vatten. READ MORE

  6. 4. Model Studies of Surface Waves and Sediment Resuspension in the Baltic Sea

    Author : Anette Jönsson; Lars Rahm; Åsa Danielsson; Tarmo Soomere; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface waves; Wave model; Wave friction velocity; Resuspension; Sediment dynamics; Nitrogen fixation; Baltic Sea; Havsvågor; Östersjön; Oceanografi; Sediment; Oceanography; Oceanografi;

    Abstract : Wave heights and periods of surface waves in the Baltic Sea have been modelled for a two-year period (1999-2000) with the wave model Hypas on an 11x11-km grid scale. There is a clear seasonal variation with higher waves during winter and lower during summer. READ MORE
