  1. 16. System studies of biogas production : comparisons and performance

    Författare :Emma Lindkvist; Magnus Karlsson; Mats Söderström; Maria Johansson; Ola Norrman Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Biogas has the potential to be part of the transition towards a more sustainable energy system. Biogas is a renewable energy source and can play an important role in modern waste management systems. Biogas production can also help recirculate nutrients back to farmland. LÄS MER

  3. 17. Withhold  or  withdraw  futile  treatment in  intensive  care : arguments supported by physicians and the general public

    Författare :Anders Rydvall; Mikael Sandlund; Ola Winsö; Niels Lynöe; Mats Johansson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Withdrawal life-sustaining treatment; Futility; Neonatal intensive care; Intentions; Hastening Death; Value-based medicine; Evidence-based medicine; Decision-making; Personal values; anestesiologi; Anaesthesiology;

    Sammanfattning : Background: Since the 60s and with increasing intensity a discussion have continued about balance between useful and useless/harmful treatment. Different attempts have been done to create sustainable criteria and recommendations to manage the situations of futile treatment near the end of life. LÄS MER

  4. 18. Structure of eukaryotic DNA polymerase epsilon and lesion bypass capability

    Författare :Nasim Sabouri; Erik Johansson; Lars Thelander; Ola Hammarsten; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA polymerase epsilon; DNA replication; Okazaki fragment; Translesion synthesis; DNA lesion; dNTP; Biochemistry; Biokemi;

    Sammanfattning : To transfer the information in the genome from mother cell to daughter cell, the DNA replication must be carried out only once and with very high fidelity prior to every cell division. In yeast there are several different DNA polymerases involved in DNA replication and/or DNA repair. LÄS MER

  5. 19. Molecular epidemiology approach : nested case-control studies in glioma and lymphoid malignancies

    Författare :Florentin Späth; Beatrice S. Melin; Carl Wibom; Ann Sofie Johansson; Ingvar Bergdahl; Ola Landgren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; B cell lymphoma; multiple myeloma; risk; repeated samples; prospective longitudinal study; nested case-control study; circulating sEGFR and sERBB2; circulating immune markers and growth factors; marker disease association; disease progression; NSHDS; Janus; linear mixed modeling; epidemiologi; Epidemiology; Oncology; onkologi;

    Sammanfattning : BACKGROUND: Nested case-control studies aim to link molecular markers with a certain outcome. Repeated prediagnostic samples may improve the evaluation of marker-disease associations. However, data regarding the benefit of repeated samples in such studies are sparse. LÄS MER

  7. 20. Pathology of dNTP dysregulation

    Författare :Phong Tran; Andrei Chabes; Erik Johansson; Ola Hammarsten; Umeå universitet; []
    Nyckelord :dNTP metabolism; DNA replication; mutation rate; cancer; heart development; RNR; SAMHD1; Rrm1; Samhd1; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Deoxyribonucleoside triphosphates (dNTPs) are precursors for DNA replication and repair. Mammalian cells have two distinct biosynthesis pathways to supply dNTPs: de novo and salvage pathways. LÄS MER
