    Sammanfattning : Every day, general anaesthetics are given to a large number of patients around the world but the cellular mechanisms of how anaesthetics act are still not clear. General anaesthetics cause the intended unconsciousness, amnesia and immobility in patients, but also side effects such as a decrease in mean arterial pressure and arrhythmia, both of which contribute to complications such as heart damage and stroke.

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by loss of motor neurons and their supporting cells in the brain, brainstem and spinal cord, resulting in muscle paresis and paralysis including the bulbar (speech, chewing, swallowing) and respiratory muscles. The average age at onset is 55 years, and death due to respiratory failure occurs 2-5 years after symptom onset in ~ 85% of cases. LÄS MER

  5. 9. Stroke and Functional Recovery - An experimental study on environmental influence and gene expression after cortical infarcts in the rat

    Sammanfattning : Abstract Stroke is the third leading cause of death in the western world, and the number one cause of disability. 85% of all strokes are ischemic. Most stroke survivors will experience recovery of function. The mechanisms behind this improvement are partly unknown, but may involve elements of both compensation and restoration. LÄS MER

  7. 10. Inflammation in Cancellous and Cortical Bone Healing

    Sammanfattning : Fractures in humans most commonly occur near the joints, in the metaphyseal bone area mainly consisting of cancellous bone. Despite this, mainly cortical fractures, located in the diaphyseal bone area, have been studied in experimental models of bone healing. LÄS MER
