    Abstract : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. READ MORE

  4. 2. Quantitative approaches for health risk assessment of environmental pollutants : estimation of differences in sensitivity, relative potencies, and margins of exposure

    Author : Fereshteh Kalantari; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Historically, quantitative health risk assessment of chemical substances is based on deterministic approaches. For a more realistic and informative health risk assessment, however, the variability and uncertainty inherent in measurements should be taken into consideration. READ MORE

  5. 3. The impact of signaling factors on intervertebral disc degeneration and regeneration - studies on disc and mesenchymal stem cells from chronic low back pain patients

    Author : Daphne Hingert; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regenerative medicine; Translational medicine;

    Abstract : INTRODUCTION: Chronic low back pain (LBP) is associated with degeneration of the intervertebral discs (IVDs). Increased expressions of pro-inflammatory cytokines such as interleukin-1β (IL-1β) and matrix metalloproteinases (MMPs) in degenerated IVDs lead to loss of proteoglycan and extracellular matrix (ECM) which affect the viability of the disc cells (DCs).
