  1. 1. Cell-Penetrating Peptides for Mitochondrial Targeting

    Författare :Carmine Pasquale Cerrato; Ülo Langel; Shana O. Kelley; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial targeting; cell-penetrating peptides; antioxidant activity; scavenging ability; oligonucleotide delivery; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Mitochondria have simply been known as the cell’s powerhouse for a long time, with its vital function of producing ATP. However, substantially more attention was directed towards these organelles once they were recognized to perform several essential functions having an impact in cell biology, pharmaceutics and medicine.

  3. 2. Modelling long-term redox processes and oxygen scavenging in fractured crystalline rocks

    Författare :Magnus Sidborn; Ivars Neretnieks; Chin-Fu Tsang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Redox chemistry; hydrogeological model; groundwater chemistry; mineral interaction; Chemical engineering; Kemiteknik;

    Sammanfattning : Under de senaste decennierna har i många länder, inkluderat Sverige, långt gångna planer utvecklats för ett djupförvar av högaktivt kärnavfall. Som en del i det svenska förvarskonceptet skall avfallet inneslutas i kopparkapslar som omslutes av återfyllnadsmaterial med mycket låg genomsläpplighet av vatten. LÄS MER

  4. 3. Bioactive nanocellulose materials for the treatment of chronic wounds

    Författare :Anna Blasi Romero; Natalia Ferraz; Daniel Aili; Uppsala universitet; []

    Sammanfattning : Chronic wounds represent a burden for the healthcare system and significantly affect the quality of life of the patients. There is currently a lack of efficient treatments but new, improved therapeutic approaches are under development. LÄS MER

  5. 4. Hypothermia and radiation. Effects on DNA, chromatin and cellular survival

    Författare :Kerstin Elmroth; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cells; temperature; irradiation; dsb; survival; fluorescent nucleoid assay; hypothermia;

    Sammanfattning : The effect of ionising radiation on cells can be modulated by several physico-chemical factors. The aim of this study was to investigate if hypothermic (sub-physiological) temperatures (2°C-28°C) may influence the effect of X-rays on cellular damage in human normal fibroblasts and in a human breast adenocarcinoma cell line, MCF-7.

  7. 5. Targeting bacterial infections by using immunomodulatory host defence peptides and proteins

    Författare :Martina Kalle; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Host dfence peptides; Sepsis; Immunomodulation; Heparin cofactor II;

    Sammanfattning : Bacterial infections and sepsis are amongst the leading causes of death worldwide. Sepsis is caused by an uncontrolled systemic host response towards an invading pathogen. Due to the engagement of various systems including cellmediated responses, the coagulation and complement cascades, treatment of sepsis remains challenging. LÄS MER
