  2. 16. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight

    Author : Sojeong Ka; Finn Hallböök; Tom Porter; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chicken; juvenile body weight; divergent selection; gene expression; DNA microarray; quantitiative RT-PCR; hypothalamus; neural plasticity; melanocortin system; endogenous retrovirus; carnitine palmitoyltransferase-1b; Neurobiology; Neurobiologi; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Abstract : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. READ MORE

  4. 17. Distribution and modulatory roles of neuropeptides and neurotransmitters in the Drosophila brain

    Author : Lily Kahsai Tesfai; Åsa M. E. Winther; Ronald Strauss; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; central complex; locomotor behavior; co-transmitter; metabotropic receptor; metabolic stress; Neurobiology; Neurobiologi; zoologi; Zoology;

    Abstract : The central complex is a prominent neuropil found in the middle of the insect brain. It is considered as a higher center for motor control and information processing. READ MORE

  5. 18. Alterations in receptor expression and function in scrapie-infected neuronal cell lines

    Author : Heléne Lindegren; Katarina Bedecs; David Brown; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurobiology; Neurobiologi;

    Abstract : This study shows that lipopolysaccharide (LPS) induces a robust, concentration-and time-dependent increase in nitric oxide (NO) production in the murine neuroblastoma cell line N2a by increased expression of iNOS. However, in scrapie-infected N2a cells (ScN2a), the LPS-induced NO production was completely abolished. READ MORE

  6. 19. Redefining suicidal behaviour – Rating scales and biomarkers

    Author : Daniel Lindqvist; Lund Psykiatri; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurobiology; Suicide; attempted; Principal component analysis; Chemokines; Cytokines; Hypothalamic-Pituitary-Adrenal-Axis; Hydroxyindoleacetic Acid;

    Abstract : Risk assessment of suicidal behaviour is one of the most important tasks in clinical psychiatry and a major determinant of subsequent care and treatment selections. To date, suicide risk assessment is based solely on clinical evaluations, which inevitably leads to subjective interpretations and decisions by the psychiatrist. READ MORE

  7. 20. Circadian plasticity in the neuromuscular junction of Drosophila melanogaster

    Author : Kerstin Mehnert; Rafael Cantera; Charlotte Helfrich-Förster; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurobiology; Neurobiologi; funktionell morfologi; Functional Zoomorphology;

    Abstract : A biological clock exists in many organisms and controls rhythmic behaviors such as the activity pattern of locomotion. At the cellular level, it has been shown that circadian rhythms in the morphology of neurons exist in the fruit fly Drosophila melanogaster. READ MORE
