  1. 11. Plasticity of the developing glutamate synapse in the hippocampus

    Författare :Therése Abrahamsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :synaptic plasticity; long-term potentiation; short-term potentiation; silent synapse; development; hippocampus; glutamate;

    Sammanfattning : Synapses are highly plastic, i.e. they have the ability to change their signaling strength both in the short- and long-term (e.g. LÄS MER

  2. 12. 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. 13. Tolerance and antagonism to allopregnanolone effects in the rat CNS

    Författare :Sahruh Turkmen; Inga-Maj Johansson; Agneta Nordberg; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; GABA-A receptor; UC1011; Spatial memory; Morris Water Maze; Tolerance; Silent second; mRNA; Obstetrics and gynaecology; Obstetrik och gynekologi;

    Sammanfattning : Many studies have suggested a relationship between sex steroids and negative mental and mood changes in women. Allopregnanolone, a potent endogenous ligand of the GABA-A receptor and a metabolite of progesterone, is one of the most accused neuroactive steroids. LÄS MER

  4. 14. Neurotoxicity of β-lactam antibiotics : experimental kinetic and neurophysiological studies

    Författare :Silvia E. Schliamser; Ragnar Norrby; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; benzylpenicillin; blood-brain barrier; ß-lactam antibiotics; CSF; CNS; EEG; imipenem cilastatin; FCE 22101; meningitis; neurotoxicity of; silent-second; thiopental; transport system; uraemia;

    Sammanfattning : The neurotoxic potential of intravenous administered benzylpenicillin (BPC) was studied in rabbits with intact blood-CNS barriers and rabbits with experimental E. coli meningitis. At onset of epileptogenic EEG activity or seizures, serum, CSF and brain tissue were collected for assay of BPC. LÄS MER

  5. 15. Techniques to Cancel Execution Early to Improve Processor Efficiency

    Författare :Mafijul Islam; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; processor design; energy-efficiency; narrow-width cache; instruction reuse; zero-value cache; resource-efficient; narrow-width load; complexity-effective; small value locality; register file cache; frequent value locality; trivial instruction; silent load; high-performance; zero load;

    Sammanfattning : The evolution of computer systems to continuously improve execution efficiency has traditionally embraced various approaches across microprocessor generations. Unfortunately, contemporary processors still suffer from several inefficiencies although they offer an unprecedented level of computing capabilities. LÄS MER
