  1. 1. Precise cell manipulations and imaging of cellular responses : Methods developed using microfluidic, 3D-printing and microfabrication technologies

    Författare :Nikos Fatsis-Kavalopoulos; Johan Kreuger; Aman Russom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : It is at the heart of biological and medical research to try and understand how cells communicate with each other, and how cells respond to alterations in their environment, including treatment with different drugs. There is in this context a continued need for better methods that allow researchers to precisely manipulate cells and their microenvironment and to study the resulting responses using high-resolution live microscopy.

  3. 2. Adherence of Staphylococcus aureus in experimental endocarditis and osteomyelitis

    Författare :Stefan A Hienz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Staphylococcus aureus has persisted and is now resurging as an important hospital and community pathogen. The microorganism can cause a wide spectrum of diseases ranging from cutaneous infections to more specific infections such as osteomyelitis and infective endocarditis (IE). Infections of bone, or osteomyelitis, remain a clinical challenge. LÄS MER

  4. 3. Experimental Investigation of Three-Dimensional Single and Double optical Lattices

    Författare :Harald Ellmann; Poul Jessen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A complete laser cooling setup was built, with focus on threedimensional near-resonant optical lattices for cesium. These consist of regularly ordered micropotentials, created by the interference of four laser beams. One key feature of optical lattices is an inherent ”Sisyphus cooling” process. LÄS MER

  5. 4. Taurine and dopamine-related effects of ethanol. An experimental study in rodents

    Författare :Lisa Ulenius; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; Alcohol; Caffeine; Nucleus accumbens; Microdialysis;

    Sammanfattning : The reinforcing properties of alcohol (ethanol) are associated with activation of the mesolimbic dopamine system and the concomitant increase in dopamine in the nucleus accumbens (nAc). Changes in this system are thought to be a predominant underlying factor in promoting excessive alcohol intake and alcohol use disorder. LÄS MER

  7. 5. Prior Knowledge and Recognition Memory : a Computational Modeling Approach

    Författare :Johan Hellman; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Recognition memory; Episodic memory; Pre-experimental familiarity; Event-Related Potentials; Item variability; Receiver-Operating Characteristics; Computational Models;

    Sammanfattning : For more than a century, an immense interest has been devoted to the study of recognition memory, where a multitude of memory phenomena has been explained. Recognition memory is usually described with parsimonious measurement and statistical models, stemming from dual process theory and signal detection theory. LÄS MER
