  2. 1. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. READ MORE

  4. 2. Sugar-modulated gene expression and cell division in cell culture and seedlings of A. thaliana

    Author : Sabine Kunz; Leszek A. Kleczkowski; Alison Smith; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; carbohydrates; cell culture; cell division; gene expression; homeostasis; live cell imaging; sugar-signals; sugar-analogues; Physiological Botany; fysiologisk botanik;

    Abstract : Throughout their life cycle, plants adjust growth in response to their developmental and environmental situation within the limits of their energetic capacities. This capacity is defined by the local sugar availability, which is constantly modulated through synthesis, transport and consumption of sugar. READ MORE

  5. 3. Measurement of sensitivity to DNA damaging agents

    Author : Sherin T Mathew; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsic sensitivity; DNA damage; ionizing radiation; cell division;

    Abstract : There is a large inter-individual variation in intrinsic sensitivity in patients receiving treatment with DNA damaging agents. Cancer therapy exemplifies this problem where patients experience varying degree of normal tissue side effects in response to radiation or chemotherapy. READ MORE

  6. 4. Genetic mechanisms regulating proliferation and cell specification in the Drosophila embryonic CNS

    Author : Shahrzad Bahrampour; Stefan Thor; Jan-Ingvar Jönsson; Simon Sprecher; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The central nervous system (CNS) consists of an enormous number of cells, and large cellular variance, integrated into an elaborate network. The CNS is the most complex animal organ, and therefore its establishment must be controlled by many different genetic programs. READ MORE

  7. 5. On the cell cycle of Escherichia coli and cell division in Haloferax mediterranei

    Author : Björn Gullbrand; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Branch; division; Escherichia coli; Haloferax mediterranei; replication; segregation; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; mikrobiologi; Microbiology;

    Abstract : Escherichia coli has served as a model organism for prokaryotes for several decades and is perhaps the most well characterised organism on earth. The use of fluorescence microscopy during recent years has contributed substantially to our understanding of the essential cell cycle processes chromosome replication, chromosome segregation and cell division.
