  1. 11. Experimental transplantation of retinal and iris pigment epithelial cells into the subretinal space

    Författare :Sven Crafoord; Jan Ulrik Prause; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A dysfunction of the retinal pigment epithelium (RPE) is the main cause for the development of age-related macular degeneration (ARMD) and visual loss in elderly people. For about 10 years experimental and clinical attempts to transplant RPE cells have been performed. LÄS MER

  3. 12. Adjusting to the extreme : Thermal adaptation in a freshwater gastropod

    Författare :Magnus Johansson; Laurila Anssi; Robby Stoks; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radix balthica; Lake Mývatn; geothermal springs; thermal adaptation; isolation by environment; population structure; gene flow; cogradient variation; AFLP; thermal preference; CTmax; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Sammanfattning : Temperature is a ubiquitous force influencing biological processes ranging from cellular responses to life span. The thermal environment for many organisms is predicted to change with globally increasing temperatures and studies conducted in natural systems incorporating various evolutionary forces, such as gene flow, is needed.

  4. 13. Hedonistic Act Utilitarianism : Action Guidance and Moral Intuitions

    Författare :Simon Rosenqvist; Folke Tersman; Jens Johansson; Ben Eggleston; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; hedonistic act utilitarianism; consequentialism; action guidance; moral intuitions; hedonism; thought experiments; ignorance; imagination; morality; normativity; ethics; moral theory; normative ethics; Filosofi; Philosophy;

    Sammanfattning : According to hedonistic act utilitarianism, an act is morally right if and only if, and because, it produces at least as much pleasure minus pain as any alternative act available to the agent. This dissertation gives a partial defense of utilitarianism against two types of objections: action guidance objections and intuitive objections. LÄS MER

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

    Författare :Laurent Roybon; Institutionen för experimentell medicinsk vetenskap; []

    Sammanfattning : 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. LÄS MER

  7. 15. Connections between biodiversity and ecosystem functioning in large-scale natural ecosystems

    Författare :James Hagan; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecology; ecosystem function; ecosystem process;

    Sammanfattning : Billions of years of evolution have given us a planet that supports a remarkable diversity of life. Estimates for the number of Eukaryotic species frequently number in the millions and the Prokaryotes are much more diverse than that. This biodiversity makes up the ecosystems that we, as humans, rely on to sustain almost every aspect of our lives. LÄS MER
