    Sammanfattning : Advancements in medical diagnostics have allowed us to understand the underlying mechanism and treat the root cause for many diseases which had been causing morbidity and mortality up until this point in human history. Furthermore, many of the standard diagnostic procedures have now been transformed to provide answers at or near the point-of-care. LÄS MER

  3. 2. Tolerance and injury mechanisms in the developing CNS

    Författare :Malin Gustavsson; Göteborgs universitet; []
    Nyckelord :hypoxia-ischemia; neonatal; brain; PARP-1; tolerance; global gene expression; apoptosis; cerebral blood flow;

    Sammanfattning : The pathophysiological mechanisms underlying the development of hypoxic-ischemic (HI) brain injury has been the subject of extensive research yet a neuroprotective strategy to limit its progression is lacking.OBJECTIVES: The aim of the present thesis was to obtain a better understanding of the mechanisms involved in neonatal HI, specifically to study I) the involvement of Poly ADP-ribose) polymerase (PARP)-1 in HI, II) the effect of hypoxic PC on brain injury and function after HI in the long-term perspective, III) the effect of hypoxic PC on global gene expression, in particular the involvement of apoptosis related genes, and IV) the vascular response to hypoxic PC.

  4. 3. Reverse transcriptase assay for analysis of resistance to anti-HIV drugs and their mechanism of action

    Författare :Xingwu Shao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV-1; RT; antiviral drugs; NRTls; NNRTls; drug resistance; viral load;

    Sammanfattning : Reverse transcriptase (RT) is a viral enzyme and one of the main targets for drugs against human immunodeficiency virus (HIV). This work presents a set of sensitive non-radioactive RT assays were developed: standard RT inhibition assay (IC assay); RT binding inhibition assay; RTprotein detection assay and template-primer destruction assay or chain termination assay (CT assay).

  5. 4. Atmospheric corrosion of copper and copper-based alloys in architecture : from native surface oxides to fully developed patinas

    Författare :Tingru Chang; Inger Odnevall Wallinder; Tomas Prošek; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Copper and copper-based alloys are commonly used in both ancient and modern architecture. This requires an in-depth fundamental and applied understanding on their atmospheric corrosion behavior at different climatic, environmental and pollutant levels and how these parameters influence e.g. LÄS MER
