  2. 1. Effects of Mobile Phone Radiation upon the Mammalian Brain

    Author : Henrietta Nittby; Sektion IV; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mobile phone; electromagnetic radiation; Blood-brain barrier; brain; rat;

    Abstract : oday about half of the world's population owns the microwave producing mobile phones. The blood-brain barrier (BBB) protects the mammalian brain from potentially harmful substances circulating in the blood. READ MORE

  4. 2. Developmental Neurotoxicity in Mice Neonatally Co-exposed to Environmental Agents : PCB, PBDE, Methyl Mercury and Ionized Radiation - Interactions and Effects

    Author : Celia Fischer; Per Eriksson; Anders Fredriksson; Richard Seegal; Uppsala universitet; []
    Keywords : Biology; PCB; PBDE; MeHg; ionized radiation; neonatal; development; neurotoxicity; behavior; cholinergic system; Biologi;

    Abstract : This thesis investigates the neurotoxic effects in mice neonatally co-exposed to different toxic environmental agents during a defined critical period of the brains's rapid growth and development. Environmental toxic agents are incorporated in our environment. READ MORE

  5. 3. Low-Dose Ionizing Radiation Induces Neurotoxicity in the Neonate : Acute or fractionated doses and interaction with xenobiotics in mice

    Author : Sonja Buratovic; Per Eriksson; Henrik Viberg; Bo Stenerlöw; Anders Fredriksson; Jean-René Jourdain; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; Neonatal; Neurotoxicity; Behaviour; Nicotine; Ketamine; Mouse; Cognition; Acute irradiation; Fractionated irradiation;

    Abstract : This thesis examines the developmental neurotoxic effects of exposure to low-dose ionizing radiation (IR), alone or together with xenobiotics, during a critical period of neonatal brain development in mice.During mammalian brain development there is a period called the brain growth spurt (BGS), which involves extensive growth and maturation of the brain.

  6. 4. Regional differences in the response of neural stem cells and their microenvironment to ionizing radiation

    Author : Nina Hellström; Göteborgs universitet; []
    Keywords : ionizing radiation; neurogenesis; neural stem cells; inflammation; microglia; stem cell niche; trophic support;

    Abstract : Radiation therapy is one of the most effective tools for treating malignant tumors; however, cranial irradiation often results in intellectual impairment and cognitive deficits, such as impaired learning and memory. Ionizing radiation generates DNA damage, causing proliferative cells to undergo apoptosis. READ MORE

  7. 5. Development of the read-out link and control board for the ATLAS Tile Calorimeter Upgrade

    Author : Eduardo Valdés Santurio; Samuel Bryant Silverstein; Costas Foudas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HL-LHC; ATLAS; Tile Calorimeter; TileCal; Demonstrator; Daughterboard; Read-out; Digital electronics; Data acquisition; Radiation tolerant; GBTx; TID; NIEL; SEU; SEL; FPGA; Kintex 7; Ultrascale; Ultrascale ; Optic Links; fysik; Physics;

    Abstract : The Phase-II upgrade plan for the ATLAS Hadronic Tile Calorimeter facing the High-Luminosity LHC (HL-LHC) era includes approximately 1000 radiation tolerant read-out link and control boards (Daughterboards) that will provide full-granularity digital data to a fully-digital trigger system off-detector through multi-Gbps optic fibres. Different Daughterboard (DB) revisions have been developed, each successively aiming to meet the demanding HL-LHC requirements. READ MORE
