  1. 1. Fluid Catalytic Cracking Catalyst Demetallization and Reactivation, Modeling of Catalytic Cracking, and Use of Microwaves to Heat Fluid Beds

    Författare :Frank J. Elvin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pilot plant; nickel and vanadium deposition; catalyst; reactivation; demetallization; catalytic cracking; and microwave heating; MAT; fluid bed;

    Sammanfattning : The fluid catalytic cracking unit (FCCU), the major conversion unit in an oil refinery, uses a silica-alumina zeolite catalyst to convert heavy hydrocarbons to light hydrocarbons. A small fraction of the catalyst must be continually replaced with fresh catalyst to maintain activity. LÄS MER

  3. 2. p53 reactivation by the small molecule RITA : molecular mechanisms

    Författare :Vera Grinkevich; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inactivation of the tumor suppressor p53 is essential for the development and maintenance of cancer cells. Therefore, reactivation of p53 appears to be a promising strategy for anti-cancer therapy. LÄS MER

  4. 3. Role of birds in the biology of Lyme disease Borrelia

    Författare :Åsa Gylfe; Klaus Kurtenbach; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lyme disease; birds; Borrelia; I. uriae; infection reactivation; stress; bipolar distribution; transequatorial transport;

    Sammanfattning : Lyme disease is a tick-transmitted illness caused by Borrelia burgdorferi sensu lato (s.l.), a group of spirochetes with at least three human pathogenic species, B. burgdorferi sensu stricto, B. LÄS MER

  5. 4. Mutant p53 reactivation by prima-1 : molecular mechanism and biological effects

    Författare :Jérémy Lambert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cancer has become one of the leading causes of death worldwide. It is now clear that tumors arise due to the malfunction of a number of genes, thus emphasising the importance of targeted therapies directed to crucial types of genetic alterations. LÄS MER

  7. 5. Dissecting the p53 pathway by means of small molecule-mediated reactivation and computational biology

    Författare :Martin Enge; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The p53 tumor suppressor is a highly connected signaling molecule with paramount importance to tumor suppression. It is activated by diverse stress signals and in response activates the transcription of affector genes that can induce several cellular processes, most importantly cell-cycle arrest and apoptosis.
