    Sammanfattning : Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has doubled, reaching 245 million tons in 2008. LÄS MER

  2. 2. Bioaccessibility, corrosion and surface properties of metals, alloys and metallic powder in biological fluids of relevance for occupational and consumer health hazard assessment

    Författare :Xuying Wang; Inger Odnevall Wallinder; Yolanda S. Hedberg; Lars Nyborg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal and alloy; metal release; synthetic biological fluids; surface oxide; corrosion resistance; hazard assessment; Kemi; Chemistry;

    Sammanfattning : When assessing hazards of metals, alloys, and metal-containing items, the metal release (bioaccessibility) is of high importance. Triggered by increasingly stricter hazard classifications for metals, especially cobalt (Co), and limited knowledge, the aim of this doctoral thesis is to assess correlations between the metal/alloy surface characteristics, corrosion and metal release pattern in different simulated biological fluids relevant to human exposure scenarios (dermal, ingestion and inhalation, Papers I-V).

  3. 3. Tissue remodelling proteases as prognostic factors in colon and rectal cancer

    Författare :Marcus Langenskiöld; Göteborgs universitet; []
    Nyckelord :extracelluar matrix; survival; staging; colorectal cancer; mucosa; stroma;

    Sammanfattning : Background: Colorectal cancer is the third most common cancer in Sweden and the main treatment is surgery. The TNM classification is the principal staging tool, although insufficient in identifying all patients with poor survival. LÄS MER

  4. 4. Evolving geriatric anthropometrics- an interplay with lifestyle changes, birth cohort effects, and survival implications. : Results from the general population study, “Good Aging in Skåne,” Sweden

    Författare :Nivetha Natarajan Gavriilidou; Geriatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometrics; BMI misclassification; measurement; error correction; prediction equation; surrogate; survival; lifestyle; birth cohort; Swedish elderly; assessment;

    Sammanfattning : There is a rising proportion of aging population worldwide. The high vulnerability of older adults to morbidity and mortality introduces an enormous health and economic burden to themselves and the society. The established leading cause of death among older adults is due to chronic and vascular diseases. LÄS MER
