1. Heart Regeneration : Lessons from the Red Spotted Newt
Sammanfattning : Unlike mammals, adult salamanders possess an intrinsic ability to regenerate complex organs and tissue types, making them an exciting and useful model to study tissue regeneration. The aims of this thesis are two fold, (1) to develop and characterize a reproducible cardiac regeneration model system in the newt, and (2) to decipher the cellular and molecular underpinnings involved in regeneration.

2. Vitamin A regulated neuronal regeneration and homeostasis
Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER
3. Gene expression and regeneration in ophiuroids: A study of transcriptional activity and regeneration in the temperate Amphiura filiformis and Antarctic Ophionotus victoriae
Sammanfattning : Regeneration, in which lost or damaged tissues are re-grown, is a common phenomenon amongst animals and especially so within the ophiuroids (brittle stars) of the phylum echinodermata. The process of regeneration begins with the injury event followed by a period of cell and tissue reorganization which results in wound healing and tissue re-growth. LÄS MER
4. The role of regeneration in plant niche differentiation and habitat specialization
Sammanfattning : To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. LÄS MER
5. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents
Sammanfattning : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. LÄS MER
