  1. 21. Effects of S(+)-, R(-)- and racemic ketamine on the brain

    Författare :Anders Schmidt; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Racemic ketamine, introduced in the mid-sixties, contains equal proportions of the enantiomersS(+)- and R(–)-ketamine. Early clinical reports indicated unfavourable effectson intracranial pressure (ICP) and on the cerebral circulation. Current literature on thistopic is however sparse, and available reports are divergent. LÄS MER

  3. 22. Optical Monitoring of Cerebral Microcirculation

    Författare :Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

    Sammanfattning : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).

  4. 23. Experimental cardiopulmonary cerebral resuscitation : with special reference to cerebral eicosanoid production and free radical scavengers

    Författare :Xiaoli Liu; Marianne Forsman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; cerebral resuscitation; reperfusion damage; oxidative injury; eicosanoid; free radical scavenger; neurological function; alkaline buffer; S-PBN; PBN; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi; Anaesthesiology;

    Sammanfattning : Reperfusion injury after restoration of spontaneous circulation (ROSC) is often considered one of the predominant factors in determining neurological outcome in cardiac arrest. Therefore one of the main targets of experimental and clinical studies has been to mitigate this reperfusion injury. LÄS MER

  5. 24. Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"

    Författare :Faina Reinprecht; Geriatrik; []

    Sammanfattning : "Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. LÄS MER

  7. 25. On innate behaviors : focus on parental behavior and aggression

    Författare :Stefanos Stagkourakis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The neural substrates orchestrating a number of social behaviors, including parental behavior and aggression, are known to exist in the hypothalamus. Through the control of the pituitary gland, the hypothalamus regulates the release of a number of hormones necessary for the physiological control of bodily functions and the expression of appropriate behaviors.
