2. 1. On Caries Risk Profiles Using Cariogram and Caries Prevention with Fluoridated Toothpaste in Orthodontic Patients

   Author : Anas H Al Mulla; Dowen Birkhed; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caries lesions. Caries model. Caries risk. Cariogram. QLF. Orthodontic bands. Saudi Arabia. Slurry rinsing. Toothbrushing. Toothpaste. Toothpaste technique. Water rinsin;

   Abstract : Objective. The aims of this thesis were to: 1) analyse caries-related factors shortly after orthodontic treatment, 2) demonstrate the usefulness of the Cariogram by presenting orthodontic patients with different caries-risk profiles, 3) compare two different toothpastes with different post brushing techniques using an in situ caries model with orthodontic bands, and 4) test the hypothesis that toothpaste slurry rinsing, combined with some other simple post-brushing advice (in this thesis called the “modified F toothpaste technique, MFTT“), would reduce the number of decayed and filled tooth surfaces (DFS) in a 2-year randomised clinical trial in orthodontic patients.

   Keywords : High performance finite element method; computational diffusion MRI; turbulent flow; vertical axis wind turbine; Cloud computing.; högprestanda finita elementmetod; beräkningsdiffusionsmagnetresonanstomografi; turbulent flöde; vertikalaxlad vindturbin; datormolnberäkning; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Biological Physics; Biologisk fysik; Computer Science; Datalogi; Engineering Mechanics; Teknisk mekanik; Mathematics; Matematik; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

   Abstract : Finite element methods have been developed over decades, and together with the growth of computer power, they become more and more important in dealing with large-scale simulations in science and industry.The objective of this thesis is to develop high-performance finite element methods, with two concrete applications: computational fluid dynamics (CFD) with simulation of turbulent flow past a vertical axis wind turbine (VAWT), and computational diffusion magnetic resonance imaging (CDMRI).

6. 4. Liver Resection for Colorectal Cancer Metastases. Prognostic Factors and Interventions Affecting Outcome

   Author : LIDEWIJ SPELT; Lund Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; artificial neural networks; chemotherapy; colorectal cancer; liver metastasis; liver resection; portal vein embolisation; prognostic factors; survival analysis;

   Abstract : Background: With a yearly incidence of 56 per 100,000 inhabitants, colorectal cancer (CRC) is one of the most common malignancies in the Western world, representing the third leading cause of cancer-related mortality. Within three years after the diagnosis of CRC, 29% of patients will have developed liver metastases. READ MORE

7. 5. Epidural Analgesia for Colorectal Cancer Surgery : Experimental and Clinical studies

   Author : Wiebke Falk; Anil Gupta; Peter Matthiessen; Hans Hjelmqvist; Jonas Åkeson; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer; epidural analgesia; local anaesthetics; colon cancer cells; inflammation; postoperative complications; pain; recurrence; disease-free survival; mortality;

   Abstract : Epidural analgesia (EA) with local anaesthetics and opioids is used for pain management after colorectal cancer (CRC) surgery. In recent years, a possible beneficial effect of EA on cancer recurrence and survival after surgery has been proposed. READ MORE
