2. 1. Population genetic analyses in the orchid genus Gymnadenia : a conservation genetic perspective

   Author : Susanne Gustafsson; Pia Mutikainen; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Genetic engineering; Orchidaceae; Gymnadenia; conservation; microsatellites; genetic structure; mating pattern; Genteknik; Genetic engineering including functional genomics; Genteknik inkl. funktionsgenomik; naturvårdsbiologi; Conservation Biology;

   Abstract : Small populations are facing a particular risk of extinction due to a lack of appropriate genetic diversity and associated negative effects, factors dealt with in the discipline of conservation genetics. Many orchid species exhibit characteristics that make them a perfect study object in the scope of conservation genetics. READ MORE

4. 2. Genetic markers in rheumatoid arthritis

   Author : Solbritt Rantapää Dahlqvist; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; family history; genetic marker; HLA B27; HLA DR4; properdin factor B; C3 complement; -antitrypsin; haptoglobin; transferrin;

   Abstract : Genetic as well as environmental factors are believed to be of importance in the etiology of rheumatoid arthritis (RA). There are a number of previous studies of genetic markers in RA, but so far no genetic linkage and only a few associations have been found. Of the associations only one (with the HLA antigen DR4) appears to be well documented. READ MORE

5. 3. Molecular epidemiology of streptococcus agalactiae : mobile elements as genetic markers

   Author : Shi-Lu Luan; Mari Norgren; Barbara Spellerberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus agalactiae; group II intron GBSi1 ; multilocus sequence typing; capsular serotype; population structure; Clinical bacteriology; Klinisk bakteriologi;

   Abstract : Streptococcus agalactiae, also designated group B streptococcus (GBS), is a Gram-positive coccus, and it is an important pathogen that causes invasive disease in neonates, pregnant adults, and non-pregnant adults with predisposing conditions. The group II intron GBSi1 is one of the major mobile genetic elements identified in S. agalactiae. READ MORE

6. 4. Biochemical and genetic markers after subarachnoid haemorrhage

   Author : Ludvig Z Csajbok; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subarachnoid haemorrhage; biochemical marker; genetic marker; outcome;

   Abstract : ABSTRACT Background: Subarachnoid haemorrhage is a devastating disease with high morbidity and mortality despite novel treatment options are available. There are no established methods to measure the brain damage occurring due to the bleed and its complications and to predict early neurological outcome of the disease. READ MORE

7. 5. Population Fragmentation and Genetic Variation in Grouse

   Author : Jobs Karl Larsson; Jacob Höglund; Stuart B. Piertney; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Bonasa sewerzowi; bottleneck; genetic drift; genetic variation; inbreeding; isolation; microsatellites; population structure; Tetrao tetrix; Biologi; Biology; Biologi;

   Abstract : In this thesis the genetic variation of two grouse species, the Chinese grouse (Bonasa sewersowi) and the Black grouse (Tetrao tetrix) was examined with neutral genetic markers: microsatellites. Habitat fragmentation and isolation leads to structuring among and loss of genetic variation within populations. READ MORE
