  1. 41. Disinhibitory and aggressive behavior in the rat. Neurohumoral mechanisms

    Författare :Anders I Svensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Effective pharmacological treatment for impulsive aggression and dysfunctional impulsive behavior is needed. These behavioral disturbences in man and impulsive-like and aggressive behavior in animals may involve serotonin (5-HT), noradrenaline (NA), GABAA receptors and steroid hormones, e.g. testosterone.

  3. 42. Clinical assessment of high-risk suicide attempters : intent, violence and biomarkers

    Författare :Jón Stefánsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: One of the most important but also difficult tasks that a physician is responsible for is to assess the suicide risk of a patient. Understanding the complex role of distal and proximal risk factors and their impact on the prediction of repetition of suicidal behavior is important to consider when assessing the risk of suicide.

    Sammanfattning : The research field of systems biology has gained a lot of interest during the last decades. Systems biology can be seen as the systematic study of complex interactions in biological systems, mainly by methods from dynamical systems theory. LÄS MER

  5. 44. Testicular blood flow : methodological and functional studies in the rat

    Författare :Jan-Erik Damber; Umeå universitet; []
    Nyckelord :;

    Sammanfattning : Different methods of measuring testicular blood flow in the rat were compared in an attempt to find an accurate method for measuring physiological testicular blood flow. It was found that both the Xenon- 133 clearance technique and the radioactive microsphere technique probably reflect true physiological blood flow in the testis. LÄS MER

  7. 45. Androgen controlled regulatory systems in prostate cancer : potential new therapeutic targets and prognostic markers

    Författare :Peter Hammarsten; Anders Bergh; Stina Häggström Rudolfsson; Pernilla Wikström; Sten Nilsson; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; prostate cancer; angiogenesis; human biopsy; androgen ablation; castration; prognostic marker; prognostic factor; growth control; VEGF; vascular endothelial growth factor; EGFR; epidermal growth factor receptor; pEGFR; phosphorylated EGFR; phosphorylated epidermal growth factor receptor; Pathology; Patologi;

    Sammanfattning : BACKGROUND: Prostate cancer is by far the most common cancer among Swedish men. Some patients have an aggressive lethal disease, but the majority of affected men have long expected survival. Unfortunately, the diagnostic tools available are insufficient in predicting disease aggressiveness. Novel prognostic markers are therefore urgently needed. LÄS MER
