1. Learning Physics through Transduction : A Social Semiotic Approach
Sammanfattning : This doctoral thesis details the introduction of the theoretical distinction between transformation and transduction to Physics Education Research. Transformation refers to the movement of meaning between semiotic resources within the same semiotic system (e.g. LÄS MER
2. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses
Sammanfattning : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. LÄS MER
3. Identification of downstream targets of Alk signaling in Drosophila melanogaster
Sammanfattning : The Drosophila gene Anaplastic lymphoma kinase (Alk) is homologous to mammalian ALK, a member of the Alk/Ltk family of receptor tyrosine kinases. In Drosophila Alk is crucial for development of the embryonic visceral mesoderm, where it is the receptor for Jelly Belly (Jeb) ligand. LÄS MER
4. Ommatidial adaptations for vision in nocturnal insects
Sammanfattning : Nocturnal vision is a demanding task for insects with small eyes. As it gets dimmer the noise imposed by the stochastic nature of photon arrival makes vision unreliable. Despite this, there are quite a number of animal species that are active at night and apparently see well. LÄS MER
5. The Role of HoxB4 in Hematopoiesis
Sammanfattning : HOXB4 is one of 39 members of the homeobox (HOX) family, a family of transcription factors involved in embryonic development. Several HOX transcription factors, including HOXB4, are highly expressed in hematopoietic stem cells (HSCs) but are downregulated upon differentiation towards more mature progeny cells. LÄS MER
