  2. 16. The allure of the exotic : The social use of non-local raw materials during the Stone Age in Sweden

    Author : Jacqueline Taffinder; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Archaeology; Arkeologi; Archaeology subjects; Arkeologiämnen; arkeologi; Archaeology;

    Abstract : By use of ethnoarchaeological method this thesis attempts to investigate the social roles of non-local raw materials. Personal ornaments are studied in a world-wide range of ethnographic contexts, attention being focused on the origin of raw materials used to make these objects and the social use they assume in the 64 different societies analysed.

  4. 17. Investigation of Mechanics of Mutation and Selection by Comparative Sequencing

    Author : Michael C. Zody; Kerstin Lindblad-Toh; Leif Andersson; Chad Nusbaum; Henrik Kaessmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chicken; chimpanzee; human; evolution; segmental duplication; structural variation; chromosomal rearrangement; comparative genomics; positive selection; selective sweep; Genetics; Genetik; Genetics; genetik;

    Abstract : The process of evolution is of both scientific and medical interest. This thesis presents several studies using complete genomic reference sequences, comparative genomic data, and intraspecific diversity data to study the two key processes of evolution: mutation and selection.

  5. 18. Human papillomavirus tropism : determinants of viral tissue specificity

    Author : Nitesh Mistry; Magnus Evander; Ola Forslund; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; papillomavirus; receptor; heparan sulfate; pI; lactoferrin; lactoferricin; transcription; long control region; tropism; Virology; Virologi;

    Abstract : Cervical cancer is the second most common cancer among women worldwide and human papillomavirus (HPV) is a prerequisit for the development of this cancer. HPV belongs to the Papillomaviridae family and infects the basal layer of epithelial cells where it generally progresses into warts or condylomas. READ MORE

  6. 19. On the Mechanisms Behind Hippocampal Theta Oscillations : The role of OLMα2 interneurons

    Author : Sanja Mikulovic; Richardson Leao; Klas Kullander; Stefan Remy; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; interneuron; optogenetics; theta oscillations; anxiety;

    Abstract : Theta activity is one of the most prominent rhythms in the brain and appears to be conserved among mammals.  These 4-12 Hz oscillations have been predominantly studied in the dorsal hippocampus where they are correlated with a broad range of voluntary and exploratory behaviors.

  7. 20. The immortalization process of T cells : with focus on the regulation of telomere length and telomerase activity

    Author : Sofie Degerman; Göran Roos; John Sedivy; Umeå universitet; []
    Keywords : immortalization; senescence; T cells; Nijmegen breakage syndrome; telomere; telomerase; hTERT; generic aberrations; methylation; MEDICINE; MEDICIN; Pathology; patologi;

    Abstract : Cellular immortalization is a major hallmark of cancer and is a multi-step process that requires numerous cell-type specific changes, including inactivation of control mechanisms and stabilization of telomere length. The telomeres at the chromosome ends are essential for genomic stability, and limit the growth potential of most cells. READ MORE
