  2. 21. Environmental Monitoring of Refuse Dump Leachate Toxicity in Fish

    Author : Erik Noaksson; Lennart Balk; Louis J. Guillette Jr; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fiskar; miljögifter; Toxicology; Toxikologi;

    Abstract : The global economy is driven by the consumption of goods and materials. Used products are often deposited on refuse dumps, making them potential point sources for all man-made chemicals. Water soaking through landfill waste results in a wastewater termed leachate. READ MORE

  4. 22. Postmortem toxicology : aspects on interpretation

    Author : Per Holmgren; Jörg Mörland; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Postmortem toxicology is a matter of analytical chemistry and the consequent interpretation of the results. Thus, both parts are of great importance to come to the right conclusion or the most probable explanation of the analytical results. READ MORE

  5. 23. Direct and indirect mechanisms for aryl hydrocarbon receptor activation mediated by 6-formylindolo[3,2-b]carbazole

    Author : Emma Wincent; Ulf Rannug; Agneta Rannug; Christopher Bradfield; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi; toxikologisk genetik; Genetic Toxicology;

    Abstract : The aryl hydrocarbon receptor (AhR) is mostly recognized for mediating the adverse effects of dioxins. In addition, endogenous activation of the AhR seems to have important biological functions.  Several studies have demonstrated an activation of the receptor when no exogenous ligand was added.

  6. 24. Assessment of eosinophil degranulation in allergic diseases and experimental models

    Author : Monika Malm-Erjefält; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood; histochemistry; cytochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; animal morphology; Animal anatomy; Djurs anatomi och morfologi; Haematology; cytoplasmic granules ; Hematologi; Respiratory system; extracellulära vätskor; Andningsorganen; toxikologi; farmaci; farmakognosi; Farmakologi; toxicology; pharmacy; pharmacognosy; Klinisk biologi; Pharmacological sciences; Histology; cell separation ; mice; animal models ; biological marker ; transmission electron microscopy allergy; cell degranulation ; Clinical biology; extracellular fluids; eosinophils;

    Abstract : In allergic disorders, the eosinophilic granulocytes migrate to affected tissues and release granule proteins with cytotoxic, immunoregulatory, and remodeling-promoting properties. Given that degranulation is reflected by a loss in eosinophil granule density of living cells, or by cell membrane rupture and release of intact granules, these morphological changes may represent a biomarker of the allergic disease.

  7. 25. Histamine and chromogranin A-derived peptides in rat stomach ECL cells

    Author : Per Norlén; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacy; pharmacognosy; Pharmacological sciences; CGRP adrenaline; galanin; VIP; PACAP; somatostatin; gastrin; microdialys; pancreastatin; chromogranin A; histamine; ECL cell; rat stomach; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : The ECL cells constitute the predominant endocrine cell population of the stomach. They secrete histamine which is a major stimulator of acid secretion. Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. READ MORE
