1. 16. Neuroactive steroids and rat CNS

   Författare :Vita Birzniece; Bo Söderpalm; Umeå universitet; []
   Nyckelord :Estradiol; progesterone; HRT; allopregnanolone; UC1011; serotonin receptor; GABAA receptor; mRNA; Morris water maze; silent second; tolerance; Clinical Neurophysiology; klinisk neurofysiologi;

   Sammanfattning : Several studies suggest profound effects on mood and cognition by neuroactive steroids. Estrogen alone or in combination with antidepressant drugs affecting the serotonin system has been used to treat mood disorders. On the other hand, progesterone is related to negative effects on mood and memory. LÄS MER

3. 17. Characterizing and modulating the effects of ionizing radiation to the juvenile hippocampus

   Författare :Malin Blomstrand; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low-dose radiation; CNS; hippocampus; apoptosis; cytokines; growth factors; microglia; medulloblastoma; hippocampal sparing; tumor bed boost; cognitive risk estimation;

   Sammanfattning : Survival rates after childhood cancer treatment have improved, leading to a growing population of survivors. Radiotherapy is an important tool for curing cancer in the brain. Unfortunately, radiotherapy is associated with late side effects e.g. LÄS MER

4. 18. Cyanide and central nervous system : a study with focus on brain dopamine

   Författare :Gudrun Cassel; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CNS; cyanide; dopaminergic system; convulsions; receptor binding; tyrosine hydroxylase; monoamine oxidase; extracellular release; inositol phosphate; GABA; GAD;

   Sammanfattning : The brain is a major target site in acute cyanide intoxication, as indicated by several symptoms and signs. Cyanide inhibits the enzyme cytochrome oxidase. This inhibition causes impaired oxygen utilization in all cells affected, severe metabolic acidosis and inhibited production of energy. LÄS MER

5. 19. Transcription Factor AP-2 in Relation to Serotonergic Functions in the Central Nervous System

   Författare :Mattias Damberg; Elias Eriksson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; CNS; serotonin; transcription factors; AP-2; personality; antidepressants; Farmakologi; Pharmacological research; Farmakologisk forskning; medicinsk farmakologi; Medical Pharmacology;

   Sammanfattning : Eukaryotic gene transcription plays a regulatory role in mammalian developmental processes. It has been shown that transcriptional control is an important mechanism for specification of neurotransmitter phenotypes. LÄS MER

7. 20. In vivo properties of neural stem cells after transplantation into the rat brain-Studies of phenotypic differentiation and functional integration using cell-specific labelling and electrophysiological techniques

   Författare :Ulrica Englund Johansson; Peter Eriksson; Lund Oftalmologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell line; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; functional integration; electrophysiology; retrograde tracing; immortalized; GFP; migration; axonal projections; glia; neuron; transplantation; stem cell. progenitor cell; CNS; Biomedical Sciences;

   Sammanfattning : In the present thesis, we have examined the in vivo properties of in vitro expanded human and rat neural stem-and progenitor cells after transplantation into the neonatal and adult rat brain. The survival and differentiation of the grafted cells were assessed using species-specific antisera, and pre-labelling with the reporter gene green fluorescent protein (GFP). LÄS MER
