2. 1. Genetic characterization of malignant melanoma and breast cancer

   Author : Göran B Jönsson; Bröstcancer-genetik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; microarray; inherited breast cancer; Melanoma; linkage analysis; cancer; Cytologi; cancerology; onkologi;

   Abstract : Malignant melanoma and breast cancer are common malignant diseases characterized by considerable heterogeneity with respect to genetics, histopathology, biology and clinical course. In breast cancer, two major susceptibility genes have been identified, BRCA1 and BRCA2, which account for a significant proportion of high-risk breast cancer families. READ MORE

4. 2. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage

   Author : Jörgen Jönsson; Lars Lövgren; Per Persson; Staffan Sjöberg; Douglas B Kent; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; schwertmannite; goethite; lepidocrocite; acid mine drainage; sulphate; natural organic matter; mineral surface; infrared spectroscopy; EXAFS; XRD; ternary surface complex; copper II ; cadmium II ; lead II ; zinc II ; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. READ MORE

6. 4. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae

   Author : Helene Larsson Jönsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; UV-B; plant nutrients; photosynthesis; oxygen evolution; chlorophyll fluorescence; Cd uptake; cadmium; Arabidopsis thaliana; Brassica napus; Plant biochemistry; Växtbiokemi; Botany; Botanik;

   Abstract : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. READ MORE

7. 5. Molecular mechanisms in lymphoid restriction : securing the B lineage fate

   Author : Josefine Åhsberg; Mikael Sigvardsson; Jan-Ingvar Jönsson; Charles G. Mullighan; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : With the work in this thesis I have aimed to deepen the understanding of the mechanisms behind the development of different blood cell lineages with a specific focus on B cell development.To understand the interplay between extracellular signaling and transcription factor networks in early lymphoid development we investigated the functional collaborations of FLT3 and IL7R.
