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

    Författare :Maria Andersson; Björn Hellman; Leif Busk; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 7. Sentinel Node in Clinical Practice : Implications for Breast Cancer Treatment and Prognosis

    Författare :Yvette Andersson; Leif Bergkvist; Jan Frisell; Jana de Boniface; Robert Mansel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breast cancer; sentinel node; micrometastases; survival; non-sentinel node metastases;

    Sammanfattning : The introduction of sentinel lymph node biopsy (SLNB) has conveyed several new issues, such as the risk of false negativity, long-term consequences, the prognostic significance of micrometastases and whether ALND can be omitted in sentinel lymph node- (SLN) positive patients.Archived SLN specimens from 50 false negative patients and 107 true negative controls were serially sectioned and stained with immunohistochemistry.

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

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

    Sammanfattning : 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. LÄS MER

  7. 10. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam

    Författare :Amir Baghdadchi; Leif Karlsson; Joel Andersson; Vahid Hosseini; Dirk Engelberg; Högskolan Väst; []
    Nyckelord :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;

    Sammanfattning : 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.
