  1. 31. Enhancement and Characterization of Films for Barrier and Release Applications

    Författare :Maria Petersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; release; edible materials; petroleum wax; starch; acetoglyceride; microstructure; water vapour permeability; phase separation; protein;

    Sammanfattning : Films and coatings can improve the quality and shelf-life of food products by acting as barriers to e.g. water vapour and oxygen. Many edible biopolymer films, based on polysaccharides and proteins, form excellent oxygen barriers but most often provide only poor water vapour barriers. LÄS MER

  2. 32. Experimental Traumatic Brain Injury and Cell Death - in vivo and in vitro aspects

    Författare :Gustav Mattiasson; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurofysiologi; neuropsychology; Neurology; uncoupling protein; mitochondrial permeability transition; cerebral blood flow; functional outcome; cell death; mitochondria; hippocampus; preconditioning; trauma; Brain; ischemia; neuropsykologi; Neurologi; neurophysiology;

    Sammanfattning : Traumatic and ischemic brain damage are major causes of disability and death. While much effort has been spent on developing pharmacological treatments for these conditions, no neuroprotective drugs are in clinical use. LÄS MER

  3. 33. Aspects of sepsis/SIRS - An experimental study on fluid therapy, vitamin C and plasma volume in increased permeability

    Författare :Björn Bark; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : In sepsis, after major surgery or severe trauma, the human body may suffer from various degrees of generalized inflammation, a syndrome called Systemic Inflammatory Response Syndrome (SIRS). One feature of SIRS is increased capillary permeability, caused by disruption of the capillary endothelium due to e.g. LÄS MER

  4. 34. Mitochondrial permeability transition following calcium overload. - Its role in neuronal cell death and potential as a pharmacological target

    Författare :Magnus Hansson; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; farmakognosi; farmaci; Bioenergetik; Bioenergetics; neuropsykologi; toxikologi; neurofysiologi; Neurologi; Neurology; neurophysiology; neuropsychology; Neurodegeneration; Mitochondria; Brain; Pharmacological sciences; pharmacognosy; pharmacy; Farmakologi; toxicology;

    Sammanfattning : There is currently no clinically available drug with neuroprotective properties to limit the evolving cell death following e.g. stroke or traumatic brain injury. The mitochondrial permeability transition (mPT) is a potential pathological mechanism causing cell death in the CNS. LÄS MER

  5. 35. Shock wave effects on the vascular endothelium

    Författare :Anders Sondén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Shock waves; cavitation; explosions; high-energy missile trauma; ESWL; laser; endothelial cells; cell membrane damage; cytoskeleton; adhesion molecules; reactive oxygen species;

    Sammanfattning : A shock wave is a pressure wave with high amplitude and a velocity above sound. Man is exposed to shock waves (SWs) in connection with trauma, e.g. explosions and high-energy missiles and medical treatments such as extracorporeal lithotripsy (ESWL). LÄS MER
