  1. 1. Teratogenicity as a consequence of drug-induced embryonic cardiac arrhythmia : Common mechanism for almokalant, sotalol, cisapride, and phenytoin via inhibition of IKr

    Författare :Anna-Carin Sköld; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; IKr; delayed rectifying K channel; embryonic cardiac arrhythmia; teratogenicity; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

    Sammanfattning : During the last years, drugs that prolong the repolarisation phase of the myocardial action potential, due to inhibition of the rapid component of the delayed-rectifying potassium channel (IKr) have been in focus. In addition to arrhythmogenic potential, selective Ikr-blockers have also been shown to be embryotoxic and teratogenic in animal studies. LÄS MER

  3. 2. Pluripotent Stem Cells of Embryonic Origin : Applications in Developmental Toxicology

    Författare :Måns Jergil; Lennart Dencker; Aldert Piersma; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Embryonic stem cell; Microarray; Toxicogenomics; Valproic acid; Developmental toxicology; Teratogenicity; Neural tube defects; Histone deacetylase inhibitor; In vitro toxicology; Toxicology; Toxikologi; Toxicology; Toxikologi;

    Sammanfattning : General toxicity evaluation and risk assessment for human exposure is essential when developing new pharmaceuticals and chemicals. Developmental toxicology is an important part of this risk assessment which consumes large resources and many laboratory animals. LÄS MER

  4. 3. The informational value and usefulness of serum retinoid measurements. Studies on biological variation, including infancy and pregnancy, and influence of fasting, antiepileptic drugs and ethanol

    Författare :Maria Berggren Söderlund; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; vitamin A deficiency; teratogenicity; ethanol; antiepileptic drugs; caloric restriction; infant; pregnant; biological variation; 13-cis retinoic acid; all-trans retinoic acid; Vitamin A; retinol;

    Sammanfattning : The aims of these studies were to evaluate retinoid measurements, more specifically the performance of all-trans and 13-cis retinoic acids methods in clinical experimental settings and to evaluate the informational value of these measurements in relation to S-Retinol. Biological and analytical variations for retinoids were evaluated for healthy subjects. LÄS MER

  5. 4. Mechanisms behind Cadmium-Induced Teratogenicity

    Författare :Estíbaliz López Fernández de Villaverde; Lennart Dencker; Ulf Eriksson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Cadmium; Teratogenesis; Exencephaly; Mechanisms; Toxikologi; Toxicology; Toxikologi;

    Sammanfattning : Heavy metals polluting our environment cause concern for developing organisms. Among them, cadmium with extremely slow elimination from the body, causes lower birth weight in humans but has not been classify as a human teratogen. Studies in different laboratory animals have shown that cadmium indeed is a potent teratogen. LÄS MER

  7. 5. Improved environmental monitoring and assessment : Establishing links between effects of chemical pollution at different levels of biological organization in a Baltic Sea bioindicator species (Monoporeia affinis)

    Författare :Martin Reutgard; Magnus Breitholtz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental health assessment; environmental monitoring; chemical pollution; hypoxia; bioindicators; biomarkers; teratogenicity; embryo toxicity; oxidative stress; acetylcholine esterase. Monoporeia affinis; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : A large number of chemicals enters the marine environment via atmospheric deposition, run-off, rivers and streams, industrial effluents and municipal wastewater. To understand how chemicals affect environmental health, monitoring and assessment approaches need to combine physical, chemical and biological effect parameters from different levels of biological organization.
