  2. 1. Search for reliable diagnostic markers for Alzheimer’s disease

    Author : Niels Andreasen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alzheimer´s disease; Mild cognitive impairment; Biochemical markers; Cerebrospinal fluid; Diagnosis; Progression; Tau-protein; Beta-amyloid; Aß42; ApoE; Sensitivity; Specificity;

    Abstract : The diagnosis of Alzheimer’s disease (AD) is rather difficult not at least in the earlier stages of the disease. The diagnostic accuracy has been reported to be around 65-90%. These figures however, come from academic centers with a special interest in the disease and are based on patients followed for several years. READ MORE

  4. 2. Characterization of a new amino acid transport system in human epidermal Langerhans cells

    Author : Niels Bendsöe; Lund Dermatologi och venereologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amino acid transport; energy charge; epidermis; glycolysis; lactate; Langerhans cells; L-dopa; mitochondria; omeprazole; Dermatology; venereology; Dermatologi; venereologi;

    Abstract : Based on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. READ MORE
