  1. 6. Cannabinoids as modulators of cancer cell viability, neuronal differentiation, and embryonal development

    Författare :Sofia Gustafsson; Stig Jacobsson; Birgitta Sander; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cannabinoids; cell viability; neuronal differentiation; colorectal cancer; chick embryo; biokemisk farmakologi; biochemical pharmacology; Toxicology; toxikologi;

    Sammanfattning : Cannabinoids (CBs) are compounds that activate the CB1 and CB2 receptors. CB receptors mediate many different physiological functions, and cannabinoids have been reported to decrease tumor cell viability, proliferation, migration, as well as to modulate metastasis. LÄS MER

  2. 7. Virtual Reality for Enriched Rehabilitation of Stroke Patients with Spatial Neglect : Diagnostics and the Rehabilitation Effect on Spatial Attention and Neuronal Activity

    Författare :Helena Fordell; Jan Malm; Anders Eklund; Hanne Krarup Christensen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; spatial neglect; rehabilitation; virtual reality; enriched environment; fMRI;

    Sammanfattning : Background: Approximately a third of all stroke patients develop spatial neglect, a debilitating symptom associated with poor outcome. Spatial neglect is clinically defined as a deficit in processing and responding to stimuli presented on the contralesional side of the body, or the space surrounding that side of the body. LÄS MER

  3. 8. Neuronal Networks of Movement : Slc10a4 as a Modulator & Dmrt3 as a Gait-keeper

    Författare :Martin Larhammar; Klas Kullander; Leif Andersson; Åsa Wallén-Mackenzie; Robert Fyffe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Synaptic vesicle transporter; Neuromodulation; Dopamine; Central Pattern Generator; Locomotion; Gait; Horse; Mouse; Commissural Inhibitory Interneuron; Neuroscience; Neurovetenskap;

    Sammanfattning : Nerve cells are organized into complex networks that comprise the building blocks of our nervous system. Neurons communicate by transmitting messenger molecules released from synaptic vesicles. Alterations in neuronal circuitry and synaptic signaling contribute to a wide range of neurological conditions, often with consequences for movement. LÄS MER

  4. 9. Role of potassium channels in regulating neuronal activity

    Författare :Göran Klement; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Potassium channels; threshold dynamics; trafficking; hERG; SMOCs; excitability;

    Sammanfattning : The firing behaviour of excitable cells is fundamental for the information processing in multicellular organisms, varying from single spikes to different forms of repetitive firing. Of the many regulators, voltage gated potassium channels play a major role. In this thesis some aspects of the potassium channel regulation of firing are explored. LÄS MER

  5. 10. Vitamin A regulated neuronal regeneration and homeostasis

    Författare :Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

    Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER
