  2. 21. Promoting health in adolescents : preventing the use of tobacco

    Author : Maria Nilsson; Urban Janlert; Lars Weinehall; Erik Bergström; Hans Stenlund; Charli Eriksson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Smoking; tobacco; prevention; intervention; adolescents; schools; evaluation; parents; Public health science; Folkhälsovetenskap; Epidemiology; epidemiologi;

    Abstract : There is a robust evidence base for the negative health effects from smoking. Smoking is linked to severe morbidity and to mortality, and kills up to half of its regular users. READ MORE

  4. 22. Characterization of α-synuclein oligomers : Implications for Lewy Body Disorders

    Author : Thomas Näsström; Martin Ingelsson; Joakim Bergström; Lars Lannfelt; Poul Henning Jensen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; Alpha-synuclein; Lewy bodies; Oligomers; Reactive aldehydes; monoclonal antibody; Medical Science; Medicinsk vetenskap;

    Abstract : Parkinson’s disease, dementia with Lewy bodies and multiple system atrophy are disorders featuring accumulation of Lewy bodies in brain. The main component of these large insoluble intracellular inclusions is the presynaptic protein alpha-synuclein (α-synuclein). READ MORE

  5. 23. Gamma-Ray Emission from Galaxy Clusters : DARK MATTER AND COSMIC-RAYS

    Author : Anders Pinzke; Lars Bergström; Olaf Reimer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galaxy clusters; gamma-rays; cosmic-rays; dark matter; High energy astrophysics; Högenergiastrofysik; teoretisk fysik; Theoretical Physics;

    Abstract : The quest for the first detection of a galaxy cluster in the high energy gamma-ray regime is ongoing, and even though clusters are observed in several other wave-bands, there is still no firm detection in gamma-rays. To complement the observational efforts we estimate the gamma-ray contributions from both annihilating dark matter and cosmic-ray (CR) proton as well as CR electron induced emission. READ MORE
