    Sammanfattning : Cognitive impairments are an increasing health problem worldwide. In the developed countries, the average life expectancy has dramatically increased over the last decades, and with an elderly population more cases of cognitive impairments appear. LÄS MER

  2. 2. 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

  3. 3. 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

  4. 4. The Impact of Nandrolone Decanoate on Neuropeptidergic Mechanisms Related to Cognition, Aggression, Reward and Dependence

    Författare :Kristina Magnusson; Fred Nyberg; Mathias Hallberg; Santi Mario Spampinato; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anabolic androgenic steroids; Nandrolone decanoate; Substance P; Dynorphin A; KOP receptor; Prodynorphin; Radioimmunoassay; Autoradiography; Morris water maze; PCR; Central nervous system; Biological research on drug dependence; Biologisk beroendeforskning; Biological Research on Drug Dependence; Biologisk beroendeforskning;

    Sammanfattning : The abuse of anabolic androgenic steroids (AAS) is becoming increasingly common and may result in a range of physiological as well as psychological effects such as altered behavior in terms of increased aggression, cognitive dysfunction and addictive behavior. AAS comprise testosterone and its derivatives, of which nandrolone is one of the more common. LÄS MER

  5. 5. CNS Targets for GH and IGF-1 : Emphasis on Their Regulation in Relation to Cognitive Processes

    Författare :Madeleine Le Grevès; Fred Nyberg; Anders Hallberg; Sigbritt Werner; Uppsala universitet; []

    Sammanfattning : The interest for the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis and its role in the central nervous system (CNS) has grown during the past decade. GH has been associated with psychological functions as sleep, mood, general well-being and learning and memory. LÄS MER
