  1. 1. Helium measuring system for on-line fuel and control rod integrity surveillance in BWRs

    Författare :Irina Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; helium measurements; helium release; fuel and control rod failures;

    Sammanfattning : Accurate supervision of fuel and control rod integrity in a nuclear reactor core is very important for maintaining a safe and reliable operation of the reactor. Fuel rod failures can cause increased doses to personnel in the power plant, increased backend costs, limitations of the reactor operation and unplanned shut downs, which can lead to large economic losses.

  2. 2. Endocrine Disruption in Amphibians : Developmental Effects of Ethynylestradiol and Clotrimazole on the Reproductive System

    Författare :Irina Gyllenhammar; Cecilia Berg; Ingvar Brandt; Lena Holm; Joakim Larsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Test system; Xenopus tropicalis; Rana temporaria; sex ratio; sex differentiation; fertility; aromatase; ovary; testis; oviduct; Biology; Biologi;

    Sammanfattning : Amphibian populations are declining world-wide and one of the suggested reasons is environmental pollutants. Studies of long-term effects on the reproductive system in frogs following larval exposure to environmental pollutants are scarce. It is therefore important to develop methods to study developmental reproductive toxicity in amphibians. LÄS MER

  3. 3. Selection of transthyretin amyloid inhibitors

    Författare :Irina Iakovleva; Anders Olofsson; Göran Larsson; Bente Westergaard; Umeå universitet; []

    Sammanfattning : Amyloidosis is a group of clinical disorders caused by the aggregation of specific proteins into abnormal extracellular deposits. Today, 31 different proteins have been linked to amyloid diseases including transthyretin-related amyloidosis (ATTR). LÄS MER

  4. 4. Purification of general RNA polymerase II transcription factors from mouse for studies of proliferation-specific transcription

    Författare :Irina Kotova; Lars-Gunnar Larsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; Genetik; Genetics; Genetik;

    Sammanfattning : Accurate initiation of transcription by RNA polymerase II depends on general transcription factors (GTFs), which include the TATA-binding protein (TBP) and the transcription factors (TF) IIB, IIF, IIE and IIH. In order to reconstitute mouse transcription in vitro, we cloned the genes encoding mouse TFIIB, and both subunits of TFIIE and TFIIF from a mouse cDNA library. LÄS MER
