1. 11. Physiological and biomechanical aspects of rifle carriage during biathlon skiing

   Författare :Malin Jonsson Kårström; Marko Laaksonen; Kerry McGawley; Guillaume Millet; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D-measurement; anaerobic energy contribution; crosscountry skiing; kinematics; lactate threshold; load carriage; oxygen uptake; performance; sex differences; sub-techniques; training;

   Sammanfattning : Biathlon is an endurance-based winter sport that combines crosscountry (XC) skiing with rifle marksmanship. While skiing, biathletes carry the rifle (weighing ≥ 3.5 kg) on their backs. However, research regarding the effects of rifle carriage in biathlon is lacking. LÄS MER

3. 12. The importance of body-mass exponent optimization for evaluation of performance capability in cross-country skiing

   Författare :Tomas Carlsson; Michail Tonkonogi; Christer Malm; Klavs Madsen; Högskolan Dalarna; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allometric scaling; power-function modelling; maximal oxygen uptake; body mass; elite skiers; distance skiing; lactate threshold; double poling; sprint skiing; competition; power output; time trial; Hälsa och välfärd; Health and Welfare;

   Sammanfattning : Introduction Performance in cross-country skiing is influenced by the skier’s ability to continuously produce propelling forces and force magnitude in relation to the net external forces. A surrogate indicator of the “power supply” in cross-country skiing would be a physiological variable that reflects an important performance-related capability, whereas the body mass itself is an indicator of the “power demand” experienced by the skier.

4. 13. The quality of red blood cells and platelets intended for transfusion : Opportunities for improvements

   Författare :Folke Knutson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; Oncology; onkologi;

   Sammanfattning : A new, automated technique for collection and instant preparation of blood components has been developed. The device enables the combined collection of red cells (250 mL) and plasma (475 mL). No adverse effects were seen in the donors. The blood components were of good quality. LÄS MER

5. 14. On microvascular blood flow assessment with the new microdialysis urea clearance technique

   Författare :Simon Farnebo; Folke Sjöberg; Ola Collin; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microdialysis; microcirculation; Plastic surgery; Plastikkirurgi;

   Sammanfattning : The aim of this thesis was to develop and evaluate a new way of monitoring blood flow with microdialysis. A thin catheter consisting of a semipermeable membrane is implanted in the tissue being studied. LÄS MER

7. 15. 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.
