1. Novel inhibitors of Chlamydia trachomatis virulence
Sammanfattning : Chlamydia trachomatis is an obligate intracellular bacterium that infects over 100 million people globally every year. Chlamydia infections can be persistent, cause infertility and blindness, adding an economical burden in the healthcare systems. LÄS MER
2. The ecological significance of cleistogamy
Sammanfattning : Various aspects of cleistogamy, a reproductive system combining selfing in closed (cleistogamous) flowers and potential outcrossing in open (chasmogamous) flowers, were investigated in four perennial species. The main purpose was to shed some light on the adaptive value of having a dual reproductive strategy, and to test some hypotheses on the maintenance of xenogamy. LÄS MER
3. Death mechanisms compromising hippocampal neurogenesis after status epilepticus
Sammanfattning : Status epilepticus (SE) leads to neurodegeneration as well as neurogenesis in the adult rat hippocampus. This thesis demonstrates that even if the neurogenic response initially is very pronounced, with a several-fold increase in cell proliferation, the survival of the newly formed neurons is compromised by a death mechanism involving mitochondria-related caspases.

4. Progenitor cells in the postnatal central nervous system, characterization and genetic manipulation
Sammanfattning : New neurons are only generated in two places of the postnatal brain; the subventricular zone (SVZ) and hippocampus. The SVZ-derived cells specifically migrate to the olfactory bulb where they give rise to new interneurons. LÄS MER
5. Experimentell bestämning av klimatanpassning hos tall (Pinus silvestris L. och Pinus contorta Dougl.)
Sammanfattning : This paper summarizes the content of three articles published in Studia Forestalia Suecica 80,81,82, 1970.A study of the annual grouuth rhythm on 2-, 3- and 20-year-old Pinus silvestris and 2-year-old Pinus contorta showed that the following methods can be used for experimental assessment of the climatic adaptation of populations and single trees: shoot- and needle elongation, bark colour onterminal, lignification of annual ring and water content of needles.
