  2. 1. β-adrenergic stimulation of VEGF gene expression : intracellular signalling pathways

    Author : Magnus J. Fredriksson; Georg Breier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

    Abstract : In the present study, the intracellular signalling pathway mediating ß-adrenergic stimulation of the expression of the vascular endothelial growth factor (VEGF) gene was investigated.VEGF is an activator of angiogenesis, the formation of new blood vessels, and is considered to be a major regulator of both physiologically and pathologically related angiogenesis, as well as being essential for development of the vascular system.

  4. 2. Estimating children’s exposure to per- and polyfluoroalkyl substances

    Author : Kerstin Winkens; Ian T. Cousins; Urs Berger; Robin Vestergren; Heather M. Stapleton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFAS; PFAA; fluorinated; fluorotelomer; FTOH; PAP; early life; child; human; exposure; intake; indoor; bedroom; air; dust; serum; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are highly stable, surface active chemicals, which are water- and oil/stain-repellent. Because of their unique properties, PFASs are widely used in consumer products. READ MORE

  5. 3. Phthalates: A Full Chain Story : Connecting phthalate sources, indoor dust, human intake, and airway symptoms in children

    Author : Anna-Sofia Preece; Carl-Gustav Bornehag; Malin Knutz; Huan Shu; Bruce Lanphear; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; children s health; endocrine disruption; exposure pathways; full chain model; human exposure; plasticizers; pregnancy; PVC; respiratory; SELMA study; Public Health Science; Folkhälsovetenskap;

    Abstract : Phthalates are widely used in a large number of consumer goods and building materials from which they can leach and contaminate the environment such as indoor dust and air. It is unclear how phthalate sources in our homes and indoor dust contribute to human intake and airway symptoms in children. READ MORE

  6. 4. Fate and exposure assessment of PCDD/Fs at contaminated sites

    Author : Annika Åberg; Karin Wiberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; contaminated sites; dioxins; PCDD F; exposure; food chain; modeling; risk assessment; physical-chemical properties; förorenade områden; dioxiner; PCDD F; exponering; födokedja; modellering; riskbedömning; fysikaliska-kemiska egenskaper; Environmental chemistry; Miljökemi;

    Abstract : Polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzo-furans (PCDFs) belong to the most toxic compounds known to science and they are defined as Persistent Organic Pollutants (POPs) under the Stock-holm Convention. The general human exposure to PCDD/Fs is primarily through dietary intake. READ MORE

  7. 5. Engineered nanomaterials in in vivo and in vitro models

    Author : Laura Abariute; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

    Abstract : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. READ MORE
