  1. 6. PET and the Multitracer Concept: An Approach to Neuroimaging Pathology

    Författare :Henry Engler; Bengt Långström; Göran Hedenstierna; Juha Rinne; Uppsala universitet; []
    Nyckelord :Neurosciences; PET Positron Emission Tomography ; multitracer; neuroimaging pathology; astrocytes; microglia; neurodegeneration; amyloid; AD; CJD; PD; Neurovetenskap;

    Sammanfattning : Patients suffering from different forms of neurodegenerative diseases, such as: Creutzfeldt Jacob Disease (CJD), Alzheimer disease (AD), mild cognitive impairment (MCI), frontotemporal dementia and Parkinson’s disease (PD) were examined with Positron Emission Tomography (PET) and the combination of different radiotracers: 15O-water, N-[11C-methyl]-L-deuterodeprenyl (DED), [18F] 2-fluorodeoxyglucose: (FDG), N-methyl-[11C]2-(4-methylaminophenyl)-6-hydroxybenzothiazole (PIB) and L-[11C]-3,4-dihydroxiphenyl-alanine (DOPA). The radiotracers and the combinations of different radiotracers were selected with the intention to detect, in the brain, patterns of neuronal dysfunction, astrocytosis, axon degeneration or protein aggregation (amyloid), in the brain which are pathognomonic for specific diseases and may contribute to improve clinical differential diagnoses.

  3. 7. Development of robust cyanobacterial strains for biotechnological applications : Stress tolerance and cell-specific expression in heterocyst-forming cyanobacteria

    Författare :Xin Li; Karin Stensjö; Yagut Allahverdiyeva-Rinne; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Dps protein; heterocysts; Nostoc; oxidative stress; cell specific promoter; ROS tolerance; synthetic biology tools transcriptional regulation.; Biokemi; Biochemistry;

    Sammanfattning : Synthetic biology tools can be used to exploit potential applications of cyanobacteria, promising photosynthetic hosts for production of fuels and chemicals. Specific genetic tools are needed for the development of robust cyanobacterial strains for bioengineering. LÄS MER

  4. 8. Study of Pumping Pressure and Stop Criteria in Grouting of Rock Fractures

    Författare :Jalaleddin Yaghoobi Rafi; Håkan Stille; Mikael Rinne; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock Mechanics; Grouting; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Today practice of grouting is based on empirical approaches in that, pumping pressure and stop criteria are determined by benchmarking similar projects. Considering a maximum limit for grouting pressure would allow applying a relatively high pressure that may lead to jacking of the fracture or even uplift of the rock mass. LÄS MER
