1. 6. Development and Characterization of a Global Brain Ischemia Model in the Mouse -A Genetic and Pharmacological Approach

   Författare :Tomas Olsson; Neuroinflammation; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurofysiologi; neuropsykologi; Neurologi; neuropsychology; Neurology; global; hypothermia; hsp70; receptor; adenosine A1; NMDA; cystatin C; cell death; hippocampus; Brain; ischemia; neurophysiology;

   Sammanfattning : Brain ischemia is a major cause of death and morbidity in the industrialized countries. It is mainly caused by stroke, but may also be the consequence of successful cardiopulmonary resuscitation in victims of cardiac arrest, known as transient global ischemia. LÄS MER

3. 7. Posture and brain function in dementia. A study with special reference to orthostatic hypotension

   Författare :Ulla Passant; Sektion IV; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; falls and fractures.; white matter disease; hypoperfusion; frontal lobes; regional cerebral blood flow; blood pressure; orthostatic hypotension; Organic dementia; normal subjects; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik;

   Sammanfattning : Orthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. LÄS MER

4. 8. Ischemic Cell Death in the CNS - applications of a new in vitro model

   Författare :Tobias Cronberg; Sektion IV; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; Neurology; astrocyte; stroke; adenosine; hyperglycaemia; glucose; free radicals; calcium; in vitro; brain ischemia; slice; neuropsychology; neurofysiologi; neurophysiology;

   Sammanfattning : Ischemic brain damage is a common cause of death and disability. A global ischemic insult is usually the result of a transient cardiac arrest while occlusion of cerebral blood vessels leads to focal ischemic lesions, commonly termed stroke. LÄS MER

5. 9. Antonyms in Context : A Corpus-Based Semantic Analysis of Swedish Descriptive Adjectives

   Författare :Caroline Willners; Allmän språkvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Nordiska språk språk och litteratur ; Scandinavian languages and literature; WordNet; semantic frameword; semantic network; sentential co-occurrence; semantic range; adjectives; antnoymy; lexical semantics; corpus-based methods; Lexicology; Lexikologi; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik;

   Sammanfattning : How are antonym relations acquired? What types of lexical information can be extracted from corpora and how? How can this information be encoded in a lexicon? The work in this book was developed within the framework of WordNet. A further elaborated lexical model is suggested, as well as methods for implementing it. LÄS MER

7. 10. Microdialysis and Intensive Care. Clinical and experimental studies

   Författare :Per Ederoth; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; traumatic brain injury; glucose; glycerol; lipolysis; epidural; postoperative analgesia; experimental pancreatitis; human; blood-brain barrier; morphine; pharmacokinetics; Microdialysis; intensive care; Anestesiologi; intensivvård;

   Sammanfattning : Microdialysis was used to monitor local concentrations of energy metabolites in different organs, and to study the pharmacokinetics of morphine over the blood-brain barrier in intact and injured brain tissue in conditions treated in the Intensive Care Unit. After major abdominal or thoracoabdominal surgery, postoperative thoracic epidural analgesia resulted in higher glycerol concentrations in the deltoid subcutaneous adipose tissue, implying increased lipolysis, on the third postoperative day as compared to intravenous infusion of morphine, possibly due to a locally increased sympathetic tone.
