  1. 21. Cerebral Hemodynamics through Intracrnial Pressure

    Författare :Sima Shahsavari; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intracranial dynamics; Baroreceptor reflex; Secondary brain injury; Traumatic brain injury; Collapsible tubes; Intracranial pressure; Cushing reflex; Pulse wave propagation; Cerebral autoregulation; Cerebral compliance; Mathematical modelling;

    Sammanfattning : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainly focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. LÄS MER

  3. 22. Role of the hERG-channel in arrhythmia and teratogenicity : studies in animal models and the human embryonic heart

    Författare :Christian Danielsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Drugs that inhibit cardiac repolarization are associated with potentially life threatening side effects in the form of ventricular arrhythmias in humans. Animal studies show that this mechanism also is relevant for the embryo, and that the circulatory depression results in hypoxia with embryotoxicity in the form of malformations and death as a consequence.

  4. 23. Cardiovascular and hematological responses to voluntary apnea in humans

    Författare :Robert de Bruijn; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organism biology; Organismbiologi;

    Sammanfattning : This thesis deals with cardiovascular and hematological responses to voluntary apnea in humans, with a special focus on O2 usage and storage. Humans, and many other air‐breathing animals, respond to apnea (breath holding) with a collection of interacting cardiovascular reflexes, which are collectively called the diving response. LÄS MER

  5. 24. Observational and experimental studies of drug treatment of infection and myocardial infarction/depression in a hospital in St. Petersburg

    Författare :Ksenia Goryachkina; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :St Petersburg; hospital; routine drug use; epidemiological studies; experimental studies; myocardial infarction; metoprolol; paroxetine; CYP2D6; antibiotics; microbial resistance; drug interaction; drug utilization;

    Sammanfattning : Introduction: Treatment of infectious and cardiac diseases represents subjects of great concern for health care all over the world, e.g. in Russia. Major problems may occur in routine use of the drugs that need to be timely considered. LÄS MER

  7. 25. Anaesthesia and analgesia for surgery in rabbits and rats : a comparison of the effects of different compounds

    Författare :Patricia Hedenqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Studies of anaesthesia and analgesia in rats and rabbit were undertaken with the aim to improve anaesthesia techniques, for better animal welfare and research quality. Induction of anaesthesia with the volatile halogenated agents isoflurane, sevoflurane and desflurane was compared in the New Zealand White rabbit. LÄS MER
