2. 1. Index theory in geometry and physics

   Author : Magnus C H T Goffeng; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Index theory; Cyclic cohomology; Regularized index formulas; Toeplitz operators; Pseudo-differential operators; Quantum Hall effect; Toeplitz operators;

   Abstract : This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and that of finding explicit analytic formulas for mapping degrees of Hölder continuous mappings.

4. 2. The relationship between overweight and depression in view of genes, environment and their joint influence

   Author : Sofia H. Kanders; Cecilia Åslund; Kent W. Nilsson; Dan Larhammar; Nancy Pedersen; Uppsala universitet; []
   Keywords : depression; overweight; obesity; plasticity; pharmacogenetics; genetics; antidepressants; breastfeeding; bullying; depression; övervikt; obesitas; plasticitet; farmakogenetik; genetik; antidepressiva läkemedel; mobbning; amning; Medicinsk vetenskap; Medical Science;

   Abstract : Obesity and depression are known to often go hand in hand, but is this due to our genetic heritage, environmental factors or a combination thereof? With a neuroscientific approach, I have investigated the relationship between obesity and depression with the aim of bridging the different levels of research available in order to better understand this complex topic. Using data from a longitudinal cohort with adults, we analysed the genetic contribution to antidepressant response in Study I.

5. 3. Neural correlates of skilled movement : functional mapping of the human brain with fMRI and PET

   Author : H Henrik Ehrsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Brain; manual dexterity inter-limb coordination; kinesthesia; motor imagery;

   Abstract : Humans have unique abilities to perform certain types of skilled voluntary movements. In this thesis we examine the neural substrates of. (i) fine digit actions, in particular the control of fingertip forces during manipulation, and (ii) the coordination of voluntary movements of different limbs. READ MORE

6. 4. Cross-cultural differences in patients with temporomandibular disorders-pain : a multi-center study

   Author : Mohammad H. Al-Harthy; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TMD-smärta; Sverige; Saudiarabien; Italien; Kvinnliga patienter; Behandling;

   Abstract : The overall objective of this thesis was to investigate patients with TMD-pain and TMD-free controls in three cultures (Saudi Arabia, Sweden, and Italy) to determine the influence of culture on and crosscultural differences in pain prevalence and intensity, sensitivity to mechanical and electrical stimulation, pain-related disability for four comorbid pain conditions (back, head, chest, and stomach pain) in the last 6 months, and the type of treatment that patients with TMD pain received. The specific aims were: (i) To determine the frequency of TMD pain in Saudi Arabians (I). READ MORE

   Abstract : Early detection is vital to successfully treating breast cancer, and mammography screening is the most efficient and wide-spread method to reach this goal. Imaging low-contrast targets, while minimizing the radiation exposure to a large population is, however, a major challenge. READ MORE
