  2. 1. Studies on interfaces between primary and secondary hemostasis

    Author : Niklas Boknäs; Tomas Lindahl; Lars Faxälv; Jon Gibbins; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Our conceptual understanding of hemostasis is still heavily influenced by outdated experimental models wherein the hemostatic activity of platelets and coagulation factors are understood and studied in isolation. Although perhaps convenient for researchers and clinicians, this reductionist view is negated by an ever increasing body of evidence pointing towards an intimate relationship between the two phases of hemostasis, marked by strong interdependence.

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motivation; Dopamine; Reward; Aversion; Negative affect; Systemic Inflammation; Drug Addiction; Cytokines; Prostaglandin E2; Melanocortin receptor 4; Acetylcholine; Muscarinic M4 receptor;

    Abstract : Various molecular pathways in the brain shape our understanding of good and bad, as well as our motivation to seek and avoid such stimuli. This work evolves around how systemic inflammation causes aversion; and why general unpleasant states such as sickness, stress, pain and nausea are encoded by our brain as undesirable; and contrary to these questions, how drugs of abuse can subjugate the motivational neurocircuitry of the brain.

    Abstract : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. READ MORE

  6. 4. Nitric oxide in central nervous structures associated with water balance and micturition

    Author : Anders Nylén; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacological sciences; spinal projections; True Blue; cystometry; circumventricular organs; paraventricular nucleus; supraoptic nucleus; NADPH diaphorase; immunohistochemistry; oxytocin; 8-arginine-vasopressin; hypothalamus; rat; micturition; nitric oxide; water balance; neuronal nitric oxide synthase; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The role of nitric oxide (NO) in the central control of water balance and micturition has not yet been established. In the present thesis, where female rats were used, neuronal NO synthase (nNOS) distribution was studied in structures of the central nervous system known to be associated with the above mentioned control.

  7. 5. Systemic and local regulation of experimental arthritis by IFN-α, dendritic cells and uridine

    Author : Sudeep Chenna Narendra; Mattias Magnusson; Srinivas Uppugunduri; Alf Kastbom; Natacha Bessis; Linköpings universitet; []
