  2. 1. On the tissue response to hafnium, titanium and thin calcium phosphate coatings

    Author : Sham Mohammadi; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hafnium; titanium; calcium phosphates; hydroxyapatite; implants; bone; soft tissue; histomorphometry;

    Abstract : Background: Titanium (Ti) is the gold standard material for load-bearing implants. Although high success rates have been reported for Ti implants, failures do occur. Alternative materials/surface modifications might further improve the performances of Ti implants, particularly in situations with non-optimal local tissue conditions. READ MORE

  4. 2. Interstitial Laser Thermotherapy of Liver Tumours. Methodology and Application

    Author : Páll Helgi Möller; Lund Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Resection; Liver; Neoplasm; Blood flow; Monitoring; Feedback control; Light penetration; Bare fibre; Sapphire probe; Nd:YAG laser; Interstitial thermotherapy; Hyperthermia; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Abstract : Interstitial laser thermotherapy (ILT) is a method well suited for selective local destruction of malignant tumours. In the present work, a laser thermotherapy system based on feedback temperature control of energy delivery (through computerised feedback system) was developed. READ MORE

  5. 3. Anastomotic leakage in colorectal surgery : early diagnosis and treatment with stent

    Author : Ioannis Oikonomakis; Kjell Jansson; Tal M. Hörer; Pär Myrelid; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anastomotic leakage; colorectal cancer; intraperitoneal microdialysis; cytokines; mRNA analysis; stent;

    Abstract : Every year inn Sweden more than 6000 individuals are diagnosed with colorectal cancer and more than 5000 operations are performed. Anastomotic leakage (AL) is the most dreaded complication in colorectal surgery and has a great impact on postoperative morbidity and mortality. READ MORE

  6. 4. Membrane transport and the human small intestine : Relation to mucosal protection, intestinal anaphylaxis and nitric oxide

    Author : Tina W. Knutson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; albumin; bicarbonate secretion; carbonic anhydrase; dopamine; duodenum; histamine; humans; hyaluronan; intestinal anaphylaxis; intestinal obstruction; jejunum; lidocaine; LOC-I-GUT; nitecapone; nitric oxide; potential difference; prostaglandins; segmental intestinal perfusion; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

    Abstract : The tightly adherent monolayer of epithelial cells that line the luminal side of the intestine provides a dynamic and highly regulated barrier to the passive and active transport of ions, water and macromolecules. Cathecol-O-methyl transferase inhibition prevents tissue degradation of catecholaminesincluding dopamine and intracellular carbonic anhydrase activity is an important regulator of ion and water transport in the small intestine.

  7. 5. Inflammatory Reactions in Peritonitis and Malignant Obstructive Jaundice : Clinical and Experimental Studies with Special Emphasis on the Cellular Immune Response

    Author : Johanna Österberg; Ulf Haglund; Mikael Ljungdahl; Roland Andersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; CLP; sepsis; peritonitis; bacterial translocation; malignant obstructive jaundice; Linomide; COX inhibitor; SC-236; indometacin; T lymphocyte; macrophage; mucosa; MLN; gut immune cell distribution; mucosal injury; cytokines; TNF-α; IL-6; IL-10; endotoxin; caspase-3; apoptosis; Kirurgi; Surgery; Kirurgi;

    Abstract : Patients with peritonitis or malignant obstructive jaundice (HPB+) have an increased morbidity and mortality due to sepsis. An altered cell-mediated immunity in the intestinal mucosa might promote gut barrier failure, increased endotoxin and cytokine release and bacterial translocation (BT) in these conditions. READ MORE
