11. Structural, Kinetic and Thermodynamic Aspects of the Crystal Polymorphism of Substituted Monocyclic Aromatic Compounds
Sammanfattning : This work concerns the interrelationship between thermodynamic, kinetic and structural aspects of crystal polymorphism. It is both experimental and theoretical, and limited with respect to compounds to substituted monocyclic aromatics. LÄS MER
12. A functional genomic investigation of an alternative life history strategy : The Alba polymorphism in Colias croceus
Sammanfattning : Life history traits affect the timing and pattern of maturation, reproduction, and survival during an organism’s lifecycle and are the major components influencing Darwinian fitness. Co-evolved patterns of these traits are known as life history strategies (LHS) and variation occurs between individuals, populations, and species. LÄS MER
13. Dopamine D2 and D3 receptors. Studies on transduction mechanisms and on the role of a D3 gene polymorphism
Sammanfattning : The neurotransmitter dopamine has been implicated in the pathophysiology of, e.g., Parkinson s disease and schizophrenia, and dopamine receptor-active compounds are commonly employed therapeutically in these and other disorders. LÄS MER
14. On the Tissue-type Plasminogen Activator (t-PA) -7,351C>T Enhancer Polymorphism. Importance for endothelial t-PA gene expression and arterial thrombotic disease
Sammanfattning : Local endothelial release of tissue-type plasminogen activator (t-PA) is an important thromboprotective mechanism. Earlier work by our group has identified a common single nucleotide polymorphism (SNP) at the t-PA locus (-7,351C>T), located within a GC-box in the retinoic acid (RA) and steroid hormone responsive t-PA enhancer.

15. Genetic diversity of the heat labile (LT) and heat stable (ST) toxins of human enterotoxigenic Escherichia coli (ETEC): New insights into polymorphism, regulation, and gene transcription
Sammanfattning : Infection with enterotoxigenic Escherichia coli (ETEC) is a leading cause of diarrhea in children in developing countries and travelers to endemic regions. ETEC is a diverse pathogen, with a wide range of virulence factors including enterotoxins and more than 25 identified colonization factors (CFs). LÄS MER
