  1. 1. On surgical techniques to reduce morbidity after anterior cruciate ligament reconstruction. The significance of harvesting technique, preconditioning, graft choice and the course of bone mineral in the calcaneus

    Författare :Lars Ejerhed; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament reconstruction; patellar tendon autograft; semitendinosus tendon autograft; preconditioning; bone mineral areal mass;

    Sammanfattning : The aim of the study was to reduce undesired postoperative effects, such as anterior knee pain, loss of sensitivity in the knee region and problems with knee-walking after anterior cruciate ligament (ACL) reconstructive surgery. Furthermore, prospectively to evaluate the bone mineral in the calcanei before and after ACL reconstruction. LÄS MER

  3. 2. Ischemic Tolerance and Cell Signaling in the Rat Brain

    Författare :Mehrdad Shamloo; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preconditioning; cell death; tyrosine phosphorylation; tolerance; ERK; Calpain; CaMKII; PKC; protection; Brain; ischemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : A brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. LÄS MER

  4. 3. DNA repair and the p53 pathway in ischemic and traumatic brain injury

    Författare :Gregor Tomasevic; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuronal death; DNA repair; knock-out mice; XPA; p53; mRNA; hippocampus; preconditioning; hypothermia; trauma; Brain; ischemia; neurobehavior; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

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

  5. 4. Inflammation and ischemia in the developing brain - modifying effects of hyperoxia and adrenoceptor activation

    Författare :Tina Markus; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenergic; preconditioning; excitotoxicity; tissue culture; hyperoxia; resuscitation; asphyxia; sensitization; TNF-alpha; inflammatory mediators; hippocampus; neonate;

    Sammanfattning : Inflammation and ischemia are common causes of perinatal brain damage. Ventilation with pure oxygen has previously been the prime choice during resuscitation following fetal asphyxia. LÄS MER

  7. 5. CFD Methods for Predicting Aircraft Scaling Effects

    Författare :Karl Pettersson; Arthur Rizzi; Bryan Richards; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Scaling Effects; Boundary Layer Transition; Preconditioning; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis deals with the problems of scaling aerodynamic data from wind tunnel to free flight  conditions. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the windtunnel should be corrected. LÄS MER
