  2. 6. Species Limits, and Evolutionary History of Glassfrogs

    Author : Santiago Castroviejo-Fisher; Carles Vilà; Jennifer A. Leonard; Miguel Vences; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amphibia; Anura; Biogeography; Centrolenidae; Diversification; Frogs; Molecular Phylogenetics; Neotropics; Pristimantis; Speciation; Species; Systematics; Taxonomy; Systematics and phylogenetics; Systematik och fylogeni; systematisk zoologi; Systematic Zoology;

    Abstract : Recognizing the mechanisms of speciation and the limits of species is essential to understand the origin of biodiversity and how to conserve it. The general aims of my investigations during my doctoral studies were two-fold: to study evolutionary patterns and processes, and to provide specific and superspecific taxonomic classifications that try to reflect evolutionary history.

  4. 7. Identification, cloning and characterization of the p53 induced gene human Wig-1

    Author : Fredrik Hellborg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The tumor suppressor p53 is a transcription factor that responds to various kinds of cellular stress. In respons to the sensed stress it is able to induces cell cycle arrest and apoptosis. In order to achieve these effects it transactivates target genes. READ MORE

  5. 8. At the Mountains of Modeling : Multiscale Simulations of Desalination by Capacitive Deionization

    Author : Johan Nordstrand; Joydeep Dutta; Oscar Tjernberg; Maarten Biesheuvel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Capacitive Deionization; Desalination; Modeling; Multiscale; Simulation; Avsaltning; Kapacitiv Avjonisering; Modellering; Multiskala; Simulering; Material and Nano Physics; Material- och nanofysik; Physics; Fysik;

    Abstract : More than 2 billion people are living in water-scarce areas. Meanwhile, there are enormous amounts of water in the salty oceans. Capacitive deionization (CDI) rises to the challenge with electrochemical cells for desalinating the water. As the CDI field expands, modeling becomes an increasingly important part of the development landscape. READ MORE

  6. 9. p38 MAPK Signalling in Endothelial Apoptosis

    Author : Simone Grethe; Malmö Experimentell patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Naturvetenskap; Natural science; PP2A; Bad; Bcl-xL; doxorubicin; TNF; p38 MAPK; Apoptosis; endothelial cells;

    Abstract : Endothelial apoptosis plays an important role in atherosclerosis, and a direct proapoptotic effect of chemotherapeutics on the tumour vasculature, emphasizes the great potency of antiangiogenic therapy in the treatment of cancer. We investigated signalling pathways in endothelial apoptosis induced by the inflammatory cytokine tumour necrosis factor alpha (TNF), the main target of which is the endothelium, and by the anticancer drug doxorubicin.

  7. 10. Engineering cyanobacteria for increased growth and productivity

    Author : Feiyan Liang; Peter Lindblad; Pia Lindberg; Olaf Kruse; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; CBB cycle; growth; biomass; photosynthesis; ethanol;

    Abstract : Increasing the photosynthetic efficiency is one of the strategies to increase the crop yields to meet the requirement of 50% more food by 2050. Due to the similarity on photosynthesis between crops and cyanobacteria, cyanobacteria are ideal alternatives to study photosynthesis since cyanobacteria are prokaryotes, easier to engineer and have shorter life cycle.
