  1. 16. A step forward in using QSARs for regulatory hazard and exposure assessment of chemicals

    Författare :Aleksandra Rybacka; Patrik Andersson; Christina Rudén; Anna Linusson; Uko Maran; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; QSAR; in silico; non-testing tools; risk assessment; exposure assessment; hazard assessment; carcinogenicity; mutagenicity; reproductive toxicity; endocrine disruption; estrogen; androgen; transthyretin; sorption; Environmental Science; miljövetenskap; Computer Science; datalogi; Toxicology; toxikologi; Statistics; statistik;

    Sammanfattning : According to the REACH regulation chemicals produced or imported to the European Union need to be assessed to manage the risk of potential hazard to human health and the environment. An increasing number of chemicals in commerce prompts the need for utilizing faster and cheaper alternative methods for this assessment, such as quantitative structure-activity or property relationships (QSARs or QSPRs).

  3. 17. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular

    Författare :Mia Stenberg; Patrik Andersson; Miriam Jacobs; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; industrial chemicals; in silico tools; molecular descriptors; non-dioxin-like PCBs; partial least-squares PLS ; principal component analysis PCA ; quantitative structure-activity relationship QSAR ; REACH; risk assessment RA ; statistical molecular design; structure-activity relationship SAR ;

    Sammanfattning : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. LÄS MER

  4. 18. Vara steget före : Bedömning av patienters smärta, näringstillstånd och hudkostym

    Författare :Carina Bååth; Christina Lindholm; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; assessment; assessment tool; skin; nutrition; pain; registered nurse; enrolled nurse; bedömning; bedömningsinstrument; hudkostym; näringstillstånd; sjuksköterska; smärta; undersköterska; Nursing; Omvårdnad; Nursing Science; Omvårdnad;

    Sammanfattning : Det övergripande syftet var att beskriva och jämföra sjuksköterskors och underskö­terskors bedömningar av patienters smärta, näringstillstånd och hudkostym samt de­ras uppfattningar om att använda bedömningsinstrument. Vidare att beskriva sjuk­sköterskors och undersköterskors uppfattningar om hur de bedömer patienters smärta, näringstillstånd och hudkostym. LÄS MER

  5. 19. Physiologically based pharmacokinetic modeling in risk assessment - Development of Bayesian population methods

    Författare :Fredrik Jonsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; methyl chloride; dichloromethane; toluene; styrene; uncertainty; intra- individual variability; risk assessment; physiologically based modeling; Markov chain Monte Carlo; PBPK; Bayesian; population modeling; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Sammanfattning : In risk assessment of risk chemicals, variability in susceptibility in the population is an important aspect. The health hazard of a pollutant is related to the internal exposure to the chemical, i.e. the target dose, rather than the external exposure. LÄS MER

  7. 20. A Risk Analysis Framework for Maritime Transport of Packaged Dangerous Goods - A Validating Demonstration (Volumes I and II) - click here to view both volumes in PDF
