  1. 11. Genes encoding homeodomain-leucine zipper proteins in Arabidopsis thaliana

    Författare :Eva Söderman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi;

    Sammanfattning : A new class of transcription factors, the homeodomain-leucine zipper (HD-Zip) proteins,have been identified in Arabidopsis thaliana. These proteins contain a homeodomainfollowed by a leucine-zipper motif, a combination so far only found in plants. LÄS MER

  3. 12. Aspects of Declarative Memory Functioning in Adulthood : Cross-Sectional and Longitudinal Studies

    Författare :Michael Rönnlund; Elizabeth Maylor; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; aging; episodic memory; sematic memory; encoding support; crosssectional; longitudinal; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : The general objective of the thesis was to examine aspects of declarative memory functioning across the adult life span. The four papers were based on data collected as part of the Betula Prospective Cohort Study (Nilsson et al., 1997) and included largescale population-based samples of participants in the age range 35 to 90.

  4. 13. Developing novel diffusion MRI methods for comprehensive analysis of restricted and anisotropic self-diffusion system

    Författare :Hong Jiang; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRI; diffusion; tissue microstructure; heterogeneity; diffusion encoding; q-vector; ;

    Sammanfattning : Diffusion MRI is a non-invasive imaging technique used to study the microstructural properties of biological tissues by observing the self-diffusion of water molecules. Traditional diffusion MRI methods, based on the pulsed gradient spin-echo sequence, employ magnetic field gradients to encode information about translational motion. LÄS MER

  5. 14. Advanced clinical MRI for better outcome in epilepsy surgery. Focusing on fMRI and prediction of verbal memory decline

    Författare :Maria Strandberg; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3T MRI; surface coils; epilepsy surgery; fMRI; TLE; lateralization index; MTL; verbal encoding;

    Sammanfattning : Abstract Aim: The aim of the thesis was to evaluate the use of advanced MRI technology to improve results of epilepsy surgery, with focus on language and memory functions. Methods: In paper I, 25 patients with drug-resistant epilepsy were retrospectively included in the study for having been referred to high resolution 3T MRI with and without surface coils. LÄS MER

  7. 15. Two is one too many : dyadic memory collaboration effects on encoding and retrieval of episodes

    Författare :Jan Andersson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The aim of the present thesis was to investigate how individual memory potential in different tasks is affected by collaboration in social settings. Collaborative group dimensions were also studied: friendship, age, and gender. The principal comparison was between an actual collaborative dyad and the sum of the two individuals' memory potential, i. LÄS MER
