  1. 26. Microbial risk assessment and its implications for risk management in urban water systems

    Författare :Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. LÄS MER

  3. 27. Psychological Resources and Risk Factors in Coronary Heart Disease : Assessment, Impact and the Influence of Mindfulness Training

    Författare :Oskar Lundgren; Margareta Kristenson; Peter Garvin; Gerhard Andersson; Lena Jonasson; J. David Creswell; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : There is strong evidence for the observation that psychological risk factors, such as depressive symptoms, hopelessness, and anxiety are associated with higher risk of developing coronary heart disease (CHD), and also contribute to a worse prognosis among CHD patients. Much less is known about psychological resources, such as Mastery, and their role in cardiovascular medicine. LÄS MER

  4. 28. Hazard assessment of ciprofloxacin, sulfamethoxazole and triclosan for marine periphyton : Ecotoxicology, Pollution Induced Community Tolerance and Co-Tolerance

    Författare :Henrik Johansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecotoxicology; Antibioitcs; Antimicrobial agents; Ciprofloxacin; Sulfamethoxazole; Triclosan; Community ecotoxicology; Periphyton; Toxicant-induced succession; Pollution-Induced Community Tolerance PICT ;

    Sammanfattning : Antibiotics and personal care products are used in large quantities and commonly detected in various environmental compartments. The two antibiotics, ciprofloxacin and sulfamethoxazole, and the personal care product triclosan are among the most commonly detected compounds in sewage treatment plants and aquatic environments.

  5. 29. Assessment of Drug-Induced Cardiotoxicity during Rat Embryo Development

    Författare :Mats Nilsson; William S. Webster; Nigel A. Brown; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The potassium ion channel (hERG/IKr) is important for normal heart function and drug-induced blockade of the channel in adult humans can lead to irregular heart rhythms (arrhythmia).  The ion channel is also essential for early cardiac function in the embryo and therapeutic drugs which block this channel have been shown to cause birth defects in animal studies.

  7. 30. Characterization of PAC-contaminated soil with the focus on availability, leachability and biological activities

    Författare :Monika M. Lam; Magnus Engwall; Maria Larsson; Patrik Andersson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polycyclic aromatic compounds; Availability; Mobility; Soil; Risk assessment; AhR-mediated activity; ER-mediated activity;

    Sammanfattning : Current risk assessments of polycyclic aromatic compounds (PACs)-contaminated soil are often based on the 16 priority PAHs and do not consider availability of PACs in soil sufficiently. This may lead to uncertainties of the assessment, since important contaminants can be overlooked and only a small fraction of contaminants is available for the uptake for organisms. LÄS MER
