11. Ecology and Control of Triatomine (Hemiptera: Reduviidae) Vectors of Chagas Disease in Guatemala, Central America
Sammanfattning : This thesis analyses several factors affecting the control of triatomines in Guatemala. There are three synantropic triatomines in Guatemala, i.e., Rhodnius prolixus, Triatoma dimidiata and T. LÄS MER
12. Brain Aromatase in the guppy, Poecilia reticulata : Distribution, control and role in behaviour
Sammanfattning : Oestrogens are produced by aromatisation of androgens by the aromatase enzyme. In the vertebrate brain this synthesis has vital functions in nerve protection, cell proliferation and nerve development during injury respectively brain development. LÄS MER
13. The role of biological processes in base cation supply in boreal forest podzols
Sammanfattning : This thesis describes experiments designed to improve understanding of biological processes contributing to supply of base cations and other nutrients in boreal forest podzols. We used microcosms containing tree seedlings growing in natural substrates, a combination of direct measurements, modelling, stable Mg isotope analysis, and 13CO2 pulse-labelling. LÄS MER
14. The Control of the Epigenome
Sammanfattning : The genetic information required for the existence of a living cell of any kind is encoded in the sequence information scripted in the double helix DNA. A modern trend in biology struggles to come to grip with the amazing fact that there are so many different cell types in our body and that they are directed from the same genomic blueprint. LÄS MER
15. Exploring the Interplay of Lipids and Membrane Proteins
Sammanfattning : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. LÄS MER
