  1. 16. Neurotoxicity of methylmercury : analysis of molecular mechanisms and behavioral alterations

    Författare :Elisabetta Daré; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Apoptosis; oxidative stress; neurons; glia; rats; dopamine; locomotion; learning and memory; environmental pollutants;

    Sammanfattning : MethyImercury (MeHg) is a global pollutant that is toxic for the nervous system, especially during development. Contaminated fish is the main route of human exposure. Recent studies have indicated that neurological alterations in humans may occur even after exposure to fairly low levels of MeHg. LÄS MER

  3. 17. Large scale synthesis of polyesters with low amount of residual tin

    Författare :Anna Stjerndahl; Ann-Christine Albertsson; Johan Lind; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : Användningen av resorberbara polymerer för applikationer inom vävnadsersättning har ökat markant under de senaste decennierna. Tekniken innebär att celler får växa på ett polymert bärarmaterial och på så sätt återskapa skadad vävnad, och är ett lovande alternativ till många av de implantat som används idag. LÄS MER

  4. 18. Mutant p53 reactivation by prima-1 : molecular mechanism and biological effects

    Författare :Jérémy Lambert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cancer has become one of the leading causes of death worldwide. It is now clear that tumors arise due to the malfunction of a number of genes, thus emphasising the importance of targeted therapies directed to crucial types of genetic alterations. LÄS MER

  5. 19. Modulation of hormone signaling by cadmium : from molecular mechanisms to health implications

    Författare :Imran Ali; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cadmium is a toxic metal classified as human carcinogen and ubiquitously found in our environment mainly from anthropogenic activities. Exposure to cadmium has been associated with increased risk of certain hormone-dependent cancers in humans, and the metal has been proposed to possess endocrine disruptive properties by mimicking the physiological actions of estrogens.

  7. 20. On the physico-chemical properties of softwood hemicellulose and compounds derived from it

    Författare :Polina Naidjonoka; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Hemicellulose is the second largest polysaccharide group available in nature after cellulose. Hemicellulose is present in plant cell walls along with cellulose and lignin. It is an abundant and biodegradable material that could potentially replace fossil-based products. LÄS MER
