2. 1. Fock Matrix Construction for Large Systems

   Author : Elias Rudberg; Pawel Salek; Itai Panas; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum chemistry; Theoretical chemistry; Teoretisk kemi;

   Abstract : This licentiate thesis deals with quantum chemistry methods for large systems. In particular, the thesis focuses on the efficient construction of the Coulomb and exchange matrices which are important parts of the Fock matrix in Hartree--Fock calculations. READ MORE

4. 2. Decellularized liver extracellular matrix as a 3D scaffold for bioengineering applications

   Author : Vamakshi Khati; Aman Russom; Håkan Jönsson; Giulia Gaudenzi; Ana Teixeira; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; liver decellularization; decellularized liver matrix bioink; bioprinting; sacrificial scaffold; viscoelasticity; bioengineering; tumor modeling; stem cell differentiation; bioreactor; Biotechnology; Bioteknologi;

   Abstract : The increasing global burden of end-stage liver disease has increased the need for liver transplantation, the definitive cure. However, there is a huge discrepancy between the number of available organ donors and the number of patients waiting for transplantation, resulting in the deaths of a significant number of patients on the waiting list as only 10% of the global need for transplantation is met.

5. 3. Collagen of the extracellular matrix. Functional and structural studies

   Author : Olof Olsson; Avdelningen för translationell cancerforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Collagen; Extra Cellular Matrix. TGF-beta; integrin αvβ6;

   Abstract : The cancer microenvironment has been attracting increasing attention as the realization of its importance for both disease treatment and malignant progression. Here the aim was to elucidate some of the effects and mechanisms of the tumor microenvironment related to the extracellular matrix (ECM). READ MORE

6. 4. Skeletal muscle matrix metalloproteinase and exercise in humans

   Author : Eric Rullman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Skeletal muscle is a highly plastic tissue; it has a great capacity to adapt to environmental demands throughout life. The structural and functional changes that occur in response to exercise training are well characterized whereas much less is known about these adaptive processes at the cellular and molecular levels.

7. 5. Sources of dioxins and other POPs to the marine environment : Identification and apportionment using pattern analysis and receptor modeling

   Author : Kristina Sundqvist; Karin Wiberg; Mats Tysklind; Paul Geladi; Miriam Diamond; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; air-water gas exchange; chiral; congener pattern; enantiomer; enantiomeric fraction; fugacity; HCH; hexachlorocyclohexane; homologue profile; indicator congener; isomer pattern; pattern analysis; PCA; PCB; PCDD F; PMF; polychlorinated dibenzofuran; polychlorinated dibenzo-p-dioxin; polychlorinated biphenyl; positive matrix factorization; principal component analysis; receptor modeling; source apportioning; source; source tracing; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar;

   Abstract : In the studies underlying this thesis, various source tracing techniques were applied to environmental samples from the Baltic region. Comprehensive sampling and analysis of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in surface sediments in Swedish coastal and offshore areas resulted in a unique data set for this region.
