  2. 1. Heritable TP53-related cancer syndrome in Sweden : characterisation of genotype-phenotype correlation and surveillance

    Author : Meis Omran; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Around 25% of all cancers are considered as familial and are caused by an inherited susceptibility to develop certain tumours. But only 5-10% are hereditary and caused by known high risk cancer genes associated with specific cancer risk syndromes. READ MORE

  4. 2. Electronic excitation, luminescence and particle emission : Studying ion-induced phenomena in ToF-MEIS

    Author : Svenja Lohmann; Daniel Primetzhofer; Friedrich Aumayr; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TOF-MEIS; ion beam analysis; deep UV; desorption; electronic sputtering; TiN;

    Abstract : Medium energy ion scattering (MEIS) is an experimental technique for the high-resolution depth profiling of thin films. Commonly, ions with energies between several ten to a few hundred keV are employed as probes, and backscattered particles are detected. READ MORE

  5. 3. Mechanisms controlling striatal projection neurone generation, from patterning to early differentiation

    Author : Håkan Toresson; Klinisk minnesforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pbx; meis; sonic hedgehog; small eye; pax6; gsh2; gsh1; cerebral cortex; striatum; telencephalon; mutant; development; mouse; embryo; retinoic acid; Clinical biology; Klinisk biologi;

    Abstract : The striatum is part of the telencephalon, the most anterior part of the vertebrate brain. From when it first can be identified, telencephalic morphology is highly complex and a wide range of mechanisms has been suggested to participate in its induction, patterning and neurogenesis.

  6. 4. Beyond scattering – what more can be learned from pulsed keV ion beams?

    Author : Svenja Lohmann; Daniel Primetzhofer; Andreas Wucher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Charge exchange; Deep UV photons; Electron emission; Silicon; Sputtering; TOF-MEIS; Fysik; Physics;

    Abstract : Interactions of energetic ions with matter govern processes as diverse as the influence of solar wind, hadron therapy for cancer treatment and plasma-wall interactions in fusion devices, and are used for controlled manipulation of materials properties as well as analytical methods. The scattering of ions from target nuclei and electrons does not only lead to energy deposition, but can induce the emission of different secondary particles including electrons, photons, sputtered target ions and neutrals as well as nuclear reaction products.

  7. 5. New aspects of electronic interactions of keV ions with matter

    Author : Barbara Bruckner; Daniel Primetzhofer; Peter Bauer; Marika Schleberger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ToF-MEIS; LEIS; electronic stopping; charge exchange; scattering potential; Fysik; Physics;

    Abstract : Low- and medium-energy ion scattering are powerful techniques to perform high-resolution depth profiling with sub-nanometer resolution. Typically, ions with primary energies between a few keV and a few hundred keV are used to probe the sample and backscattered projectiles are detected. READ MORE
