1. 16. Hygiene at CT and MRI

   Författare :Charlotte Palmqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Preventing the spread of infections is a constant battle against microorganisms. Hospital-acquired infections (HAIs) with multidrug-resistant (MDR) bacteria are a global problem today and causes suffering for patients and have high costs for society. LÄS MER

3. 17. Stereotactic imaging in functional neurosurgery

   Författare :Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; pallidotomy; thalamotomy; Parkinson s disease; essential tremor; CT; MRI; neurokirurgi; Neurosurgery;

   Sammanfattning : Background: The birth of stereotactic functional neurosurgery in 1947 was to a great extent dependent on the development of ventriculography. The last decades have witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders. LÄS MER

4. 18. Interaction between Calcium, Calciotropic Hormones and the Gastrin-ECL-cell Axis

   Författare :Rebecca Gagnemo Persson; Hälsofrämjande komplexa interventioner; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; rat; chicken; parathyroid gland; stomach; vitamin D; PTH; CT; calciotropic hormones; Gastrin; calcium; ECL cell; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Histology; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

   Sammanfattning : Calcium homeostasis involves mainly the interaction of PTH, vitamin D and CT. The stomach may be important for calcium homeostasis. Gastric acid is thought to mobilize calcium from the diet, thereby facilitating the absorption of calcium in the small intestines. LÄS MER

5. 19. Trauma - Diagnostics and Triage

   Författare :Fredrik Linder; Kevin Mani; Hampus Eklöf; Claes Juhlin; Martin Björck; Pål Aksel Naess; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wounds and injuries; trauma; triage; whole body computed tomography in trauma; compliance; radiation exposure; CT; radiation safety; Surgery; Kirurgi;

   Sammanfattning : Trauma is a leading cause of death worldwide and it reduces years of productive life and leads to disability. Effective trauma care relies on triage, which aims to ration the use of fine resources to patients with the greatest needs. LÄS MER

7. 20. High resolution laboratory x-ray tomography for biomedical research : From design to application

   Författare :Till Dreier; Lund Medicinsk strålningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray; computed tomography; micro-CT; nano-CT; phase contrast; biomedical; super-resolution; material decomposition;

   Sammanfattning : Laboratory x-ray micro- and nano-tomography are emerging techniques in biomedical research. Through the use of phase-contrast, sufficient contrast can be achieved in soft tissue to support medical studies. LÄS MER
