    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Mixtures; Developmental toxicology; Endocrine disrupting chemicals; Metabolism; Feminization; Zebrafish; Chicken embryo; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Abstract : Humans and wildlife are continuously exposed to mixtures of environmental pollutants. Mixture toxicity can be challenging to predict due to interactions between chemicals and thus whole-mixture approaches are crucial in toxicology. READ MORE

  4. 2. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds

    Author : Cecilia Berg; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Avian embryo; test system; xeno-estrogen; endocrine disruption; reproductive organ differentiation; oviduct; testis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Abstract : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. READ MORE

  5. 3. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg : Implications for developmental neurotoxicity

    Author : Marie Andersson; Ingvar Brandt; Cynthia de Wit; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; BMAA; beta-N-methylamino-L-alanine; milk; secretion; amino acid transporter; autoradiography; metabolism; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. READ MORE

  6. 4. Reactions to novelties : Developmental aspects

    Author : Kerstin Andersson; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psychology; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : The present thesis considers different aspects of infants' and children's reactions to novelties, that is, unfamiliar persons, objects, and situations. In Study I, the developmental phenomenon stranger wariness was investigated from a temperamental perspective. READ MORE

  7. 5. Metacognition and Confidence : Mood, Individual Differences, Developmental and Social Aspects

    Author : Anna-Carin Jonsson; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Developmental; Eyewitness memory; Individual Differences; Calibration; Realism in confidence judgments; Metacognition; Psykologi; psychology; psykologi; developmental; eyewitness memory; individual differences; calibration; realism in confidence judgments; metacognition;

    Abstract : This dissertation investigates the realism in people's confidence judgments. Study I investigated whether mood influences the confidence people have in their event memory. However, there were no significant differences in the realism of the participants' confidence judgments between conditions (elated and neutral). READ MORE
