  1. 41. Quantitative methods for tumor imaging with dynamic PET

    Författare :Ida Häggström; Anne Larsson; Mikael Karlsson; Lennart Johansson; Jens Sörensen; Magnus Dahlbom; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dynamic positron emission tomography; PET; tumor imaging; compartment modeling; Monte Carlo; radiofysik; radiation physics;

    Sammanfattning : There is always a need and drive to improve modern cancer care. Dynamic positron emission tomography (PET) offers the advantage of in vivo functional imaging, combined with the ability to follow the physiological processes over time. LÄS MER

  3. 42. Centrosome aberrations and tumor development

    Författare :Kaoru Fujioka; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Centrosome; cervical carcinoma; adrenocortical tumor; tetraploidization; p53; griseofulvin; 13-cis-retinoic acid.;

    Sammanfattning : The transformation of a normal cell to a tumor cell is a result of a failure somewhere in a complicated system of coordination, checkpoints and control mechanisms of inhibitors and activators working as triggers and transactivators of genes of importance for cell cycle progression. In the present thesis, the focus is on an important function that controls the segregation of the chromosomes during cell division to the next generation of two daughter cells. LÄS MER

  4. 43. Radiolabeled HER-2 Binding Affibody Molecules for Tumor Targeting : Preclinical Studies

    Författare :Ann-Charlott Steffen; Jörgen Carlsson; Vladimir Tolmachev; Lars Gedda; Ragnar Hultborn; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicine; HER-2; affibody; 211At; tumor targeting; targeted radiotherapy; molecular imaging; Biomedicin; Microbiology; Mikrobiologi;

    Sammanfattning : Conventional cancer treatment based on radiotherapy or chemotherapy affects all dividing cells. By directing the therapy specifically to the tumor cells, normal cells can be spared. Tumor targeting molecules carrying a cytotoxic moiety is then an attractive approach. LÄS MER

  5. 44. Beyond Survival - Cognition after Pediatric Brain Tumor

    Författare :Ingrid Tonning Olsson; Lund Pediatrik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pediatric Brain Tumor; Cognition; Late sequelae; Cranial Radiation Therapy; Neuropsychology;

    Sammanfattning : Background: Pediatric Brain Tumor (PBT) survivors suffer from cognitive sequelae, especially within the areas of cognitive tempo, attention, executive function and memory. The cognitive difficulties are often accentuated over the years, but knowledge about the long term trajectory is still scarce. LÄS MER

  7. 45. Novel Interactors of X-linked Inhibitor of Apoptosis Protein : Expression and Effects on Tumor Cell Death

    Författare :Håkan Steen; Dan Lindholm; Bertrand Joseph; Uppsala universitet; []
    Nyckelord :Neurobiology; XIAP; tumor cell death; apoptosis; caspases; basic helix-loop-helix protein; Neurobiologi;

    Sammanfattning : Programmed cell death, or apoptosis, has during the last decade received a lot of attention due to its involvement in a large number of pathological conditions. Since death is always irreversible, it is important for cells to fully control the initiation and execution of this process. LÄS MER
