    • Multicellular spheroids have proven suitable as three-dimensional in vivo-like models of non-vascularized micrometastases. Unlike monolayer-based models, spheroids mirror the cellular milieu and the pathophysiological gradients inside tumor nodules. However, there is limited knowledge of the radiation effects at the molecular level in spheroids of human origin. The present study is a presentation of selected cell biological processes that may easily be analyzed with methods available at routine pathology laboratories. Using gamma irradiated pancreatic neuroendocrine BON1 and colonic adenocarcinoma HCT116 spheroids as model systems, the present study assessed the radiobiological response in these models. Spheroid growth after irradiation was followed over time and molecular responses were subsequently assessed with immunohistochemistry (IHC) staining for descriptive analyses and semi-automatic grading of apoptosis, G(2)-phase and senescence in thin sections of the spheroids. Growth studies demonstrated the BON1 spheroids were slower growing and less sensitive to radiation compared with the HCT116 spheroids. IHC staining for G2-phase was primarily observed in the outer viable P-cell layers of the spheroids, with the 6 Gy irradiated HCT116 spheroids demonstrating a very clear increase in staining intensity compared with unirradiated spheroids. Apoptosis staining results indicated increased apoptosis with increasing radiation doses. No clear association between senescence and radiation exposure in the spheroids were observed. The present results demonstrate the feasibility of the use of multicellular spheroids of human origin in combination with IHC analyses to unravel radiobiological responses at a molecular level. The present findings inspire further investigations, including other relevant IHC-detectable molecular processes in time-and radiation dose-dependent settings.

  • Calculated fission-fragment mass yields and average total kinetic energies of heavy and superheavy nuclei
  • 2020
  • Ingår i: European Physical Journal A. - : Springer Science and Business Media LLC. - 1434-6001 .- 1434-601X. ; 56:2

    • Fission-fragment mass and total-kinetic-energy (TKE) distributions following fission of even-even nuclides in the region 74 ≤ Z≤ 126 and 92 ≤ N≤ 230 , comprising 896 nuclides have been calculated using the Brownian shape-motion method. The emphasis is the region of superheavy nuclei. To show compatibility with earlier results the calculations are extended to include earlier studied regions. An island of asymmetric fission is obtained in the superheavy region, 106 ≤ Z≤ 114 and 162 ≤ N≤ 176 , where the heavy fragment is found to be close to 208Pb and the light fragment adjusts accordingly. Most experimentally observed α-decay chains of superheavy nuclei with Z> 113 terminate by spontaneous fission in our predicted region of asymmetric fission. In these cases, the pronounced large asymmetry is accompanied by a low TKE value compatible with measurements.

  • Extensive Gamma-ray Spectroscopy of Normally and Superdeformed Structures in 61Cu
  • 2008
  • Ingår i: European Physical Journal A. Hadrons and Nuclei. - : Springer Science and Business Media LLC. - 1434-6001. ; 36:3, s. 251-278

    • A largely extended experimental knowledge of the Cu-61(29)32 nucleus has been obtained from three experiments. Excited states in Cu-61 were produced via the fusion-evaporation reaction Si-28(Ar-36, 3p)Cu-61. In addition to the Ge array GAMMASPHERE, neutron and charged-particle detectors placed around the target position were used for high-performance particle spectroscopy. The constructed level scheme includes more than 160 energy levels and 320 gamma-ray transitions belonging to both normally deformed as well as superdeformed rotational structures. The multipolarities have been determined for the gamma-ray transitions and as a result spin-parity assignments are given for nearly all energy levels. Experimental results in the normally deformed region are compared with predictions from large-scale shell model calculations. The collective structures are compared with results from cranked Nilsson-Strutinsky calculations. The results reveal the need to modify the standard Nilsson parameters in the mass A similar to 60 region.

  • Retro-mediation, Commodore 64, and Interoperational Devices
  • 2022
  • Ingår i: Artifact & Apparatus: Journal of Media Archaeology. ; :2, s. 1-18
  • Tidskriftsartikel (refereegranskat)abstract
    • While research on retrocomputing has stressed the cultural importance of learning from practices such as retrogaming and preservation, this article emphasizes the material practices developed within retrocomputing communities, namely the electronic engineering of various hardware, which seeks to make older technologies operative in a present media ecology. Focusing on hardware designs for the Commodore 64, this articles analyzes their (joint and emergent) media specificities, raising the issue of what is, in fact, being "re-presenced." Wolfgang Ernst's diagrammatic media archaeography serves as a guiding method to produce materially grounded insights into the temporal transformation of digital culture and how chronologically disconnected functionalities tied to specific machinery can, when systematically joined, bridge, erase, or transform the relation between new and old media.

  • Development of EGF-conjugated liposomes for targeted delivery of boronated DNA-binding agents
  • 2002
  • Ingår i: Bioconjugate chemistry. - : American Chemical Society (ACS). - 1043-1802 .- 1520-4812. ; 13:4, s. 737-743

    • Liposomes are of interest as drug delivery tools for therapy of cancer and infectious diseases. We investigated conjugation of epidermal growth factor, EGF, to liposomes using the micelle-transfer method. EGF was conjugated to the distal end of PEG−DSPE lipid molecules in a micellar solution and the EGF−PEG−DSPE lipids were then transferred to preformed liposomes, either empty or containing the DNA-binding compound, water soluble acridine, WSA. We found that the optimal transfer conditions were a 1-h incubation at 60 °C. The final conjugate, 125I-EGF−liposome−WSA, contained approximately 5 mol % PEG, 10−15 EGF molecules at the liposome surface, and 104 to 105 encapsulated WSA molecules could be loaded. The conjugate was shown to have EGF-receptor-specific cellular binding in cultured human glioma cells.

  • Introductory experiments on ligand liposomes as delivery agents for boronneutron capture therapy
  • 2003
  • Ingår i: International Journal of Oncology. - 1019-6439 .- 1791-2423. ; 23:2, s. 461-467

    • Liposomes are, when coupled to receptor ligands, candidates for receptor mediated delivery of boron for tumour therapy since they have capacity to deliver large amounts of boron per receptor interaction. With EGF-liposomes we present a pegylated ligand liposome delivery vehicle, containing water soluble boronated phenanthridine, WSP1, or water soluble boronated acridine, WSA1, for EGFR targeting. In the case of WSA1 a ligand dependent uptake was obtained and the boron uptake was as good as if free WSA1 was given. No ligand dependent boron uptake was seen for WSP1 containing liposomes. Thus, WSA1 is a candidate for further studies. Approximately 10(5) boron atoms were in each liposome. A critical assessment indicates that after optimization up to 10(6) boron atoms can be loaded. Since it is known that, for therapeutic effect, approximately 10(8)-10(9) boron atoms are needed in a single tumour cell it is realized that 10(2)-10(3) receptor interactions are needed to meet the demand. Tests applying cultured glioma cells indicate, without optimization of the delivery conditions, a boron uptake in the ppm range, which is necessary for successful BNCT. Thus, it seems possible to kill micro-invasive tumour cells with targeted liposomes if the delivery conditions are optimal.

  • Radiobromination of monoclonal antibody using potassium [76Br] (4 isothiocyanatobenzyl-ammonio)-bromo-decahydro-closo-dodecaborate (Bromo-DABI)
  • 2004
  • Ingår i: Nuclear Medicine and Biology. - 0969-8051 .- 1872-9614. ; 31:2, s. 205-11

    • The use of charged linkers in attaching radiohalogens to tumor-seeking biomolecules may improve intracellular retention of the radioactive label after internalization and degradation of targeting proteins. Derivatives of polyhedral boron clusters, such as closo-dodecaborate (2-) anion, might be possible charged linkers. In this study, a bifunctional derivative of closo-dodecaborate, (4-isothiocyanatobenzyl-ammonio)-undecahydro-closo-dodecaborate (DABI) was labeled with positron-emitting nuclide (76)Br (T 1/2 = 16.2 h) and coupled to anti-HER2/neu humanized antibody Trastuzumab. The overall labeling yield at optimized conditions was 80.7 +/- 0.6%. The label was proven to be stable in vitro in physiological and a set of denaturing conditions. The labeled antibody retained its capacity to bind to HER-2/neu antigen expressing cells. The results of the study demonstrated feasibility for using derivatives of closo-dodecaborate in indirect labeling of antibodies for radioimmunoPET.
