  1. 21. Biomarkers of ionising radiation relevant to carcinogenesis : Dose, dose rate and LET dependency of the responses

    Författare :Milagrosa López Riego; Andrzej Wojcik; Lovisa Lundholm; Alexandros G. Georgakilas; Stockholms universitet; []

    Sammanfattning : A better understanding of the relationship between ionising radiation (IR) dose, dose rate and radiation quality, and the risk of stochastic effects would improve risk extrapolation from atomic bomb survivors’ data. Owing to insufficient statistical power of epidemiological studies to detect excess incidence of cancer following low doses of IR delivered at low dose rates (LDLDR), as typically encountered in most common human exposure scenarios, radiobiological experiments are fundamental to describe the biological effectiveness of LDLDR and to define the underlying molecular mechanisms.

  3. 22. Studies of Stroma Formation and Regulation in Human Pathological Conditions and in Experimental in vivo Models

    Författare :Alejandro Rodriguez; Christian Sundberg; Kristian Pietras; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fibrosis; Tumor Stroma; Myofibroblast; Pericyte; Angiogenesis; Inflammation; adenovirus; Tumour biology; Tumörbiologi; Molecular medicine; Molekylär medicin; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Fibrosis is a sequel of chronic inflammation and is defined as an excessive deposition of collagen that ultimately leads to organ dysfunction. To date there are no effective treatments for fibrosis. The main cell type involved in collagen deposition and organization is the myofibroblast. LÄS MER

  4. 23. Cardiomyocyte Cell Cycle, Renewal and Isolation

    Författare :Stuart Walsh; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; binucleation; Cardiomyocytes; surface marker; troponin-T; mitosis; microarray; cell cycle; FACS;

    Sammanfattning : Heart disease results from the loss of cardiomyocytes following myocardial damage and is a leading cause of death worldwide. Stimulating the endogenous regeneration of cardiomyocytes or isolating them from in vitro culture is an attractive therapeutic strategy. LÄS MER

  5. 24. Timing Matters : Wounding and entomopathogenic nematode infection kinetics

    Sammanfattning : Over time, insects have developed complex strategies to defend themselves against presenting threats. However, in the evolutionary arms race of survival, pathogens have adapted to quickly overcome the immune response mounted by the host. LÄS MER

  7. 25. Oxidized nucleotides as a predictor of radiation sensitivity

    Författare :Ali Pour Khavari; Siamak Haghdoost; Marie Öhman; Anders Nilsson; Bo Stenerlöw; Neus Visa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 8-oxo-dG; Radiation; Sensitivity; Oxidized; Nucleotides; ROS; NOS; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The direct and indirect effects of IR can lead to DNA damage and activation of DNA repair. The indirect effects of ionizing radiation mediated by reactive oxygen species (ROS) which produced through radiolysis of water and if not taken care of by the antioxidant system, can also give rise to oxidative stress.
