  2. 1. Carbon Dioxide and Water Vapour Exchange within a Norway Spruce Canopy

    Author : Lasse Tarvainen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrogen allocation; optimality; stomatal conductance; photosynthesis; resource use efficiency; stem respiration; conifer;

    Abstract : Terrestrial ecosystems can act both as sinks and sources in the global carbon cycle. Forests are an important part of this system and a good understanding of their carbon balance is essential for assessments of the future climate and for evaluating mitigation strategies. READ MORE

  4. 2. Epithelial stem cells in Hutchinson-Gilford progeria syndrome

    Author : Tomás McKenna; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hutchinson-Gilford progeria syndrome (HGPS) and restrictive dermopathy (RD) are two rare genetic disorders that affect children. Complications from cardiovascular disease, including atherosclerosis, are the most common cause of death in HGPS, which occurs at around 13 years of age. READ MORE

  5. 3. Effects of enhanced ultraviolet-B radiation on subarctic ecosystems

    Abstract : Biologically harmful ultraviolet-B radiation (UV-B, 280-320 nm) is increasing at the Earth´s surface owing to stratospheric ozone depletion. This is of global concern due to potential impacts of enhanced UV-B radiation on the biosphere. READ MORE

  6. 4. CRISPR Screens Identify Candidate Therapeutic Targets in Leukemia

    Author : Maria Rodriguez Zabala; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute myeloid leukemia; CRISPR screen; leukemia stem cell; cell surface receptor; metabolism; immunotherapy; CXCR4; GLUT1; TFR1; H2-K1;

    Abstract : Acute myeloid leukemia (AML) is a complex hematological malignancy marked by proliferation of immature myeloid cells with a dismal 5-year survival. A major challenge is the persistence of leukemia stem cells (LSCs) after standard treatment, leading to relapse. READ MORE

  7. 5. Monitoring primary carbon metabolism in plants using heavy isotope labelling and mass spectrometry : ¹³CO₂ labelling, detection and estimation in intact plants

    Author : Pernilla Linden; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis covers the possibilities and limitations of studying primary metabolism in intact plants, with special focus on heavy isotope labelling and mass spectrometry methodology. In paper I, a series of Arabidopsis thaliana mutants lacking one or both genes of mitochondrial malate dehydrogenase (mMDH characterised) were characterised. READ MORE
