1. 1. Gene transfer by interspecific hybridization in bryophytes

   Författare :Weerachon Sawangproh; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; homozygote; heterozygote; admixture; single nucleotide polymorphism; STRUCTURE; PCoA; hybrid index; inbreeding; outbreeding; hybrid depression; heterosis; phylogeny; purging selection; genetic purging; genotype; phenotype; sympatry; allopatry;

   Sammanfattning : The role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms. Bryophytes have haplodiplontic life cycles with a dominant haploid generation. LÄS MER

3. 2. Artificial neural networks in models of specialization and sympatric speciation

   Författare :Niclas Norrström; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Naturvetenskap; Natural sciences;

   Sammanfattning : This thesis deals with specialization and how it is linked to sympatric speciation. The trait driving specialization is a cue recognition trait modelled with artificial neural networks that exploiters use to discriminate beneficial resources from detrimental resources based on the signals of the resources.

4. 3. Arterial Thrombosis in Factor V Leiden or Activated Protein C Resistance. Clinical and Experimental Studies

   Författare :Ellis Sampram; Malmö Klinisk koagulationsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Activated protein c resistance; Factor V Leiden mutation; thrombophilia; hypercoagulable state; Factor V Leiden mice; arterial thrombosis; venous thromboembolism; peripheral vascular reconstructions; peripheral vascular reconstruction occlusion;

   Sammanfattning : Abstract The last two decades has seen an avalanche of studies establishing Activated protein C (APC) resistance due to Factor V Leiden mutation as the most prevalent genetic risk factor, yet known, for venous thromboembolism. This has been documented in 20-60% of patients with deep vein thrombosis (DVT). LÄS MER

5. 4. Olfactory Function : The Influence of Demographic, Cognitive, and Genetic Factors

   Författare :Margareta Hedner; Maria Larsson; Lars-Göran Nilsson; Claire Murphy; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Olfaction; odor identification; odor threshold; odor discrimination; aging; gender; ApoE; BDNF; val66met; association study; population-based; Psychology; psykologi;

   Sammanfattning : Olfactory function is affected by demographic, cognitive, and genetic factors. In the present thesis, three empirical studies investigated individual differences in olfactory ability. Study I explored demographic and cognitive correlates in common olfactory tasks; odor detection, odor discrimination, and odor identification. LÄS MER

7. 5. Mutation Analysis and Hypercholesterolemia: Studies in FH patients and in healthy middle-aged men with high, low, or increasing cholesterol levels during a six-year follow-up (the CRISS study)

   Författare :Ulf Ekström; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; LDL receptor; Mutation; risk factor; FH; familial hypercholesterolemia;

   Sammanfattning : Our aims were to characterize familial hypercholesterolemia (FH) in a Swedish FH population and to further elucidate the clinical expression and treatment response in relation to genotype. Secondly, we wanted to identify gene variants, which may have impact on cholesterol levels in apparently healthy subjects. LÄS MER
