  1. 1. Porins of Borrelia burgdorferi

    Author : Marija Pinne; Sven Bergström; Magnus Höök; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lyme disease; P13; paralog; P66; channel-forming activity; porin; Medical microbiology; Medicinsk mikrobiologi;

    Abstract : Borrelia burgdorferi is a pathogenic spirochete which cycles between its arthropod vector and vertebrate host. If transmitted to humans, B. burgdorferi causes Lyme disease, an infection which can impair different organs, such as the skin, joints, nervous system and heart. READ MORE

  2. 2. Chromatin remodeling and dna topology in transcription and genome stability

    Author : Jenna Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Eukaryotic DNA is wrapped around histone proteins to form nucleosomes, the fundamental repeati ng unit of chromatin. DNA packaging into chromatin both solves and creates problems. It allows the centimeters, or even meters, of DNA that constitute a eukaryotic genome to fit inside a micrometer - scale cell nucleus. READ MORE

  3. 3. Exploring the Cell Cycle of Archaea

    Author : Magnus Lundgren; Rolf Bernander; William Margolin; Uppsala universitet; []
    Keywords : Microbiology; Archaea; Cell cycle; Replication; Mitosis; Cell division; Mikrobiologi;

    Abstract : Archaea is the third domain of life, discovered only thirty years ago. In a microscope archaea appear indistinguishable from bacteria, but they have been shown to be more closely related to eukaryotes than to bacteria. Especially central information processing is homologous to that of eukaryotes. READ MORE

  4. 4. Prediction of function shift in protein families

    Author : Saraswathi Abhiman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Protein function; Divergence; Function shift; Subfamily;

    Abstract : With the availability of a large number of complete genome sequences, it has become essential to annotate the protein sequences derived from them as precisely as possible. Even though presently available computational methods can predict broad functionality for most protein sequences, there is room for improvement in order to get more precise functional annotation.

  5. 5. Pathogenic Neisseria : Single cell motility, multicellular dynamics and antimicrobial susceptibility

    Author : Olaspers Sara Eriksson; Ann-Beth Jonsson; Matthew Francis; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Neisseria; Type IV pili; Twitching motility; PilT; Microcolony dynamics; PilU; NafA; Antimicrobial peptide; Cell-penetrating peptide; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Neisseria meningitidis and Neisseria gonorrhoeae can colonize humans without causing any symptoms. However, gonorrhea and invasive meningococcal disease are serious health concerns. An essential virulence factor for neisserial adhesion to host cells, twitching motility and microcolony formation/aggregation is the retractile type IV pili (Tfp). READ MORE
