  1. 1. Characterization of stress-inducible short-chain dehydrogenases/reductases (SDR) in plants : study of a novel small protein family from Pisum sativum (pea)

    Författare :Nikolai Scherbak; Åke Strid; Jan Rydström; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Biology; Biologi; Biology; Biologi;

    Sammanfattning : In pea (Pisum sativum), the short-chain alcohol dehydrogenase-like protein (SAD) gene family consists of at least three members (SAD-A, -B, and -C). The SAD genes are transiently expressed in plants after short exposures to ultraviolet-B radiation, which in turn leads to formation of SAD protein in leaf and stem tissue upon prolonged irradiation.

  3. 2. How can an organism´s life experience affect their descendants? Insights from epigenetic and transgenerational effects of chemical exposure in zebrafish

    Författare :Mélanie Blanc; Steffen Keiter; Joëlle Rüegg; Xavier Cousin; Nikolai Scherbak; Michael K. Skinner; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neurotoxicity; behavior; RNA-Seq; RRBS; TEI; permethrin; PCBs; PBDEs; coumarin 47;

    Sammanfattning : Environmental pollution causes approx. 10% of human diseases, and some develop in the progeny because of parental exposure. Effects passed on to subsequent generations may be a consequence of genetic mutations, or of inherited changes in epigenetic patterns. LÄS MER

  4. 3. Enterococcal distribution and responses toenvironmental waters

    Författare :Ebraheem M. Elmarghani; Jana Jass; Per-Erik Olsson; Nikolai Scherbak; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Enviromental Science; Miljövetenskap; Mikrobiologi; Microbiology;

    Sammanfattning : The release of antibiotics and pharmaceuticals into environmental waters contribute to the increasing risk of antibiotic resistant bacteria. The spread of antibiotic resistant bacteria in the environment increases the health risks to the community. Enterococci are fecal indicator bacteria (FIB) in aquatic environments for determining water quality. LÄS MER

  5. 4. Molecular and phenotypical toxicological effects of environmental pollutants and their mixtures : A mechanistic approach

    Författare :Greta Nilén; Steffen Keiter; Maria Larsson; Nikolai Scherbak; Magnus Engwall; Malin Celander; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental pollutants; mixtures; soil; zebrafish; Danio rerio; behavior; gene expression; lipidomics; image analysis; PCB126; PFOS; B[a]P; Arsenic; risk assessment;

    Sammanfattning : Current environmental risk assessment of polluted sites primarily relies on single compound evaluation. However, in the environment, organisms are often exposed to complex mixtures of pollutants. LÄS MER
