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

    Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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. 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 : NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; 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

  5. 3. Regulatory programs controlling profileration during Drosophila nervous system development

    Author : Erika Gunnar; Stefan Thor; Jan-Ingvar Jönsson; Udo Häcker; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES;

    Abstract : The central nervous system (CNS) is the most complex organ in the body, responsible for complex functions, including thinking, reasoning and memory. The CNS contains cells of many different types, often generated in vast numbers. READ MORE

  6. 4. Identification of Unique Hematopoietic Stem Cell Properties

    Author : Jens Nygren; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; Hematologi; extracellulära vätskor; Haematology; extracellular fluids; cell cycle; fusion; transdifferentiation; plasticity; Medicine human and vertebrates ; Medicin människa och djur ; quiescence; hematopoietic stem cell; self-renewal;

    Abstract : Hematopoietic stem cells (HSC) are sufficient and required for life long production of all blood cell lineages. Steady state HSCs are largely quiescent and we demonstrate that the kinetics of HSC cell cycling are slower compared to more committed progenitor cells also during expansion and self-renewal ex vivo and in physiological conditions.

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

    Author : Björn Gullbrand; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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.
