  1. 1. Exposure to xenobiotic chemicals disrupts metabolism, rhythmicity and cell proliferation in Drosophila melanogaster

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Hao Cao; Uppsala universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xenobiotics; metabolism; insulin signalling; circadian rhythm; carcinogen; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Sammanfattning : Most species are constantly exposed to xenobiotic chemicals through multiple routes. Among all categories of xenobiotics, phthalates and bisphenols are two of the most widely used plasticizers and can be found in polyvinyl chloride (PVC) materials, medical devices and even drinking water.

  2. 2. Development of methods for determining aflatoxins in biological material

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Anders Kussak; Umeå universitet.; [1995]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aflatoxins; Mycotoxins; Carcinogen; Airborne dust; Urine; Feed factories; Immunoaffinity extraction; Solid-phase extraction; Post-column derivatization; Electrospray; Mass spectrometry;

    Sammanfattning : In this thesis, it is shown how aflatoxins can be determined in biological material. The thesis is a summary of five papers.Aflatoxins are carcinogenic mycotoxins produced by Aspergillus moulds. Methods were developed for the determination of aflatoxins in samples of airborne dust and human urine collected at feed factories. LÄS MER

  3. 3. Toxicity of smokeless tobacco in human oral epithelium with emphasis on carcinogen metabolism and regulation of programmed cell death

    Detta är en avhandling från Stockholm : Karolinska Institutet, Institute of Enviromental Medicine

    Författare :Martin Vondracek; Karolinska Institutet.; Karolinska Institutet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The oral mucosa is globally a common site for cancer development. Primary risk factors include tobacco smoking and alcohol consumption whereas the contribution from usage of smokeless tobacco remains debated. LÄS MER

  4. 4. A novel technology for studying the disposition of drugs and toxicants in the lung : Short inhalation exposures of the isolated and perfused rat lung to respirable dry particle aerosols

    Detta är en avhandling från Stockholm : Karolinska Institutet, Institute of Enviromental Medicine

    Författare :Pär Ewing; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerosol; inhalation; rat; lung; absorption; drugs; carcinogen; particles;

    Sammanfattning : The disposition of solutes following the deposition of inhaled substances in the lung is a complex process that proceeds along parallel paths; passive diffusion of solutes through the air/blood barrier and local metabolism followed by blood-borne clearance to the circulation. Using the isolated and perfused lung (IPL) the pulmonary disposition of inhaled particles can be studied in great detail without interference from distal organs and systemic exposure. LÄS MER

  5. 5. The role of endogenous hypercholecystokininemia and hypergastrinemia in growth and carcinogenesis of the exocrine pancreas

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Ming Chu; Linköpings universitet.; Linköpings universitet.; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Sammanfattning : The gut hormones cholecystokinin (CCK) and gastrin are phylogeneticallyand structurally related. Under normal conditions, CCK regulates growth of the exocrine pancreas and gastrin growth of the oxyntic mucosa of the stomach. LÄS MER
