  1. 1. Life-charting patients with treatment-refractory affective disorder

    Författare :Anna Ehnvall; Göteborgs universitet; []
    Nyckelord :Life charting; treatment-refractory affective disorder; sensitisation; ; CRH challenge test; ACTH; MHPG; perception of parental rearing;

    Sammanfattning : Introduction:In treatment-refractory affective illness there are several hypothesis to suggest alterations in the neurobiological systems in relation to illness course. The underlying mechanisms have been scantily investigated. LÄS MER

  3. 2. Molecular genetic studies on cerebrospinal fluid monoamine metabolites in psychotic patients and healthy individuals

    Författare :Dimitrios Andreou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cerebrospinal fluid CSF ;

    Sammanfattning : Dopamine, serotonin and noradrenaline are the major monoamines in the human central nervous system (CNS) and following their basic pathways they are degraded to their major metabolites homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA) and 3-methoxy-4-hydroxyphenylglycol (MHPG), respectively. The cerebrospinal fluid (CSF) concentrations of the three monoamine metabolites (MM) are considered to reflect the monoamine turnover rates in the CNS, are under genetic influence and have been associated with schizophrenia.

  4. 3. Neurochemical and neuroendocrine reactions during non-neurological surgery

    Författare :Rolf Anckarsäter; Göteborgs universitet; []
    Nyckelord :albumin; beta-2-microglobulin; blood brain barrier; cerebrospinal fluid; infammation; spinal anesthesia; stress;

    Sammanfattning : Abstract Objective: To study changes in serum and cerebrospinal fluid (CSF) proteins, monoamine metabolites and hormones during non-neurological surgery. Subjects and methods: Thirty-five patients without neurological or psychiatric disorders undergoing knee replacements had CSF and serum samples drawn from spinal and arterial catheters before, three hours after and on the morning after surgery.

  5. 4. Season of birth in suicidology : neurobiological and epidemiological studies

    Författare :Jayanti Chotai; Hans Ågren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; season of birth; CSF monoamine metabolites; suicide method; borderline;

    Sammanfattning : Background: Several neuropsychiatrie disorders have shown season of birth associations. Low cerebrospinal fluid (CSF) levels of the serotonin metabolite 5-HIAA and the dopamine metabolite HVA have been associated with suicidal behaviour, impulsivity, and aggression. LÄS MER

  7. 5. Self-rated aggression. Psychobiological aspects and gender issues in medical-psychiatric practice

    Författare :Helena Prochazka; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; self-rated aggression; questionnaire; AQ-RSV; physical aggression; verbal aggression; hostility; anger; monoamine metabolites; platelet MAO activity; testosterone; fibromyalgia; depression; gender; sex; female;

    Sammanfattning : Background. The complexities of human aggression are of vital research interest in numerous scientific disciplines. In medical research, aggression is generally studied by means of self- or observer-rated inventories, clinical observations, or neurobiological research. Objectives. LÄS MER
