2. 6. Chemically Induced DNA Damage in Extended-term Cultures of Human Lymphocytes

   Author : Maria Andersson; Björn Hellman; Leif Busk; Uppsala universitet; []
   Keywords : Toxicology; Comet assay; DNA-damaging agents; DNA repair; Extended-term Cultures of Human Lymphocytes; Genotoxicity; Induced DNA damage; In vitro; Mouse Lymphoma Cells; Primary Cell Cultures; Reactive Oxygen Species; Toxikologi;

   Abstract : Generation of DNA damage is regarded to be an important initial event in the development cancer. Consequently, a battery of tests have been developed to detect different types of genotoxic effects in order to be able to predict the potential genotoxicity and mutagenicity of chemicals, including both pharmaceutical drugs and various types of environmental and occupational agents, as well as dietary factors.

4. 7. Identification and characterisation of the novel mammalian gene family Elovl

   Author : Abolfazl Asadi; Leif Andersson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

   Abstract : Comparative analysis is one of the foremost tools in biology. The most common comparative method is sequence alignment, which can be performed in many ways. By using any sort of alignments, competing sequences are evaluated by scoring schemes for estimating similarity. READ MORE

5. 8. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam

   Author : Amir Baghdadchi; Leif Karlsson; Joel Andersson; Vahid Hosseini; Dirk Engelberg; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; Laser welding; Additive manufacturing; Direct Energy Deposition using a Laser Beam; Microstructure characterization; Duplexa rostfria stål; Lasersvetsning; Additiv tillverkning; Metalldeponering med laser; Mikrostruktur; Production Technology; Produktionsteknik;

   Abstract : Duplex stainless steels (DSSs), with a ferritic-austenitic microstructure, are used in a wide range of applications thanks to their high corrosion resistance and good mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding of the relations between composition, processing thermal cycles, resulting microstructures and properties.

6. 9. Genetic Analysis of Fat Metabolism in Domestic Pigs and their Wild Ancestor

   Author : Frida Berg; Leif Andersson; Maria Moller; Stefan Marklund; Sigbjörn Lien; Uppsala universitet; []
   Keywords : Genetics; Pig; Quantitative Trait Locus; Fat deposition; FAT1; Linkage map; RH map; Comparative map; Backcross; Identical by Descent mapping; Brown adipose tissue; UCP1; Genetik;

   Abstract : The domestication of the pig began about 9 000 years ago and many of the existing domestic breeds have been selected for phenotypic traits like lean meat and fast growth. Domestic pigs are phenotypically very different from the ancestral wild boar that has adapted to survive in their natural environment. READ MORE

7. 10. Meiotic Recombination in Human and Dog : Targets, Consequences and Implications for Genome Evolution

   Author : Jonas Berglund; Matthew Webster; Kerstin Lindblad-Toh; Leif Andersson; Nadia Singh; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; recombination; biased gene conversion; CpG island; copy number variation; substitutions; methylation; Bioinformatics; Bioinformatik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Molekylär genetik; Molecular Genetics;

   Abstract : Understanding the mechanism of recombination has important implications for genome evolution and genomic variability. The work presented in this thesis studies the properties of recombination by investigating the effects it has on genome evolution in humans and dogs. READ MORE
