  4. 3. Processing, stability and interactions of lung surfactant protein C

    Författare :Jing Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mature SP-C is a 4.2 kDa transmembrane protein which is uniquely expressed in the alveolar type II cell. Human SP-C is generated via multistep proteolytic cleavage of both the C-terminal and Nterminal regions of proSP-C. LÄS MER

  5. 4. Cerebrovascular disease and dementia : a population-based study

    Författare :Li Zhu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Antihypertensives; apolipoprotein E; cognitive decline; dementia; incidence; prevalence; stroke;

    Sammanfattning : Several vascular factors have been related to cognitive decline and dementia. One of the recent efforts has been focused on stroke, which could be prevented with appropriate measures. The data for this thesis were derived from the baseline and first follow-up of the Kungsholmen Project. LÄS MER

  7. 5. Cardiovascular health and brain aging : a population-based MRI study

    Författare :Yuanjing Li; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Deterioration of brain structure and cognitive function occurs as individuals reach advanced age. The former can be observed through various markers of cerebral small vessel disease on magnetic resonance imaging (MRI) scans and the later can be assessed by neuropsychological tests and clinical examinations.
