  2. 1. Correlated materials : models and methods

    Author : Hugo Strand; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; correlated electrons; Hubbard model; multiband Hubbard model; dynamical mean field theory; exact diagonalization; Landau theory; Mott metal-insulator transition; Gutzwiller method; many-body point group symmetry; ironchalcogenides; Kanamori interaction; Slater-Condon interaction;

    Abstract : This thesis encompass a series of studies on methods and models for electron systems with local interactions, relevant for correlated materials. The first study focus on the canonical model for local correlation, the Hubbard model. READ MORE

  4. 2. Derivation, propagation and differentiation of human stem and progenitor cells

    Author : Mathilda Zetterström Axell; Göteborgs universitet; []
    Keywords : Human embryonic stem cells; neural progenitor cells; stem cells; differentiation; propagation; migration; cell culturing; rostral migratory stream; electrospun scaffolds;

    Abstract : Neuronal loss is a common feature of many neurological disorders, including stroke, Parkinson’s disease, Alzheimer’s disease and traumatic brain injury. Human embryonic stem cells (hESCs) and hESC-derived neural progenitors (NPs) may provide a number of new ways for studying and treating diseases and injuries in the brain. READ MORE

  5. 3. Stem Cell Plasticity Controlling Neuronal Differentiation Prior to Cell Transplantation

    Author : Laurent Roybon; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Differentiation; Stem cells; Immunology; serology; Immunologi; serologi; transplantation;

    Abstract : Parkinson's disease (PD) is the second most common neurodegenerative disease and affects 2% of the population over 65 years of age. The disease is characterized by the progressive loss of dopaminergic neurons. Over time, symptoms increase and, in particular, lead to a dramatic slowness of movements. READ MORE

  6. 4. Oral lichen planus : studies of factors involved in differentiation, epithelial mesenchymal transition and inflammation

    Author : Karin Danielsson; Karin Nylander; Ylva Britt Wahlin; Linda Boldrup; Jesper Reibel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oral lichen planus; differentiation; inflammation; autoimmune; premalign; odontologi; Odontology; patologi; Pathology;

    Abstract : Background: Lichen planus is a chronic inflammation of skin and mucosa with unknown cause. Oral Lichen Planus, OLP, affects around 2% of the population. Autoimmunity has been suggested as a possible cause as the disease has autoimmune features such as female predominance, cyclic nature and cytotoxic T-cell infiltrate. READ MORE

  7. 5. NEURAL STEM/PROGENITOR CELLS IN THE POST-ISCHEMIC ENVIRONMENT: Proliferation, Differentiation and Neuroprotection

    Author : Jonas Faijerson; Göteborgs universitet; []
    Keywords : neural stem cells; neural progenitor cells; stroke; ischemia; reactive astrocytes; astrogliosis; proliferation; differentiation; neurogenesis; excitotoxicity; transfection; neuroprotection;

    Abstract : Stroke is one of the leading causes of chronic disability and death in the Western world. Today, no treatment can repair the cellular loss associated with an ischemic lesion. READ MORE
