  2. 16. Molecular consequences of cellular UDP-glucose deficiency

    Author : Juan Carlos Higuita V; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A Chinese hamster fibroblast mutant cell line, deficient in UDP-glucose (UDPG), denoted as Qc, and its counterpart cell line with normalized levels of UDPG (G3), were used to determine some molecular consequences of chronic UDPG deficiency. The UDPG deficient cells lacked glycogen, had elevated rates of glucose uptake and a decreased capacity to synthesize glycogen after 120h of culture. READ MORE

  4. 17. Prognostic markers in prostate cancer : studies of a watchful waiting cohort with long follow up

    Author : Andreas Josefsson; Anders Bergh; Pernilla Wikström; Pär Stattin; Anders Bjartell; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Immunohistochemistry; Prognostic markers; biomarkers; Survival analysis; human; pathology; watchful waiting; tissue micro array; Endoglin; von willebrandt factor; ki67; ki-67; hyaluronan; patologi; Pathology;

    Abstract : Background: Prostate Cancer (PC) is a common and highly variable disease. Using current diagnostic methods, the prostate specific antigen (PSA) blood test and histological grading of prostate tissue needle biopsies, it is often difficult to evaluate whether the patient has a PC that requires active treatment or not.

  5. 18. Computer simulations of electronic energy transfer and a molecular dynamics study of a decapeptide

    Author : Maria Lindberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronic energy transfer; Monte Carlo simulations; two-particle model; GAF-theory; anisotropic systems; fluorescence depolarization ratios; Brownian Dynamics; rotating donors; Molecular Dynamics; peptide; renin inhibitor;

    Abstract : Electronic energy transfer has been investigated in pure donor systems by means of computer simulations. Calculated properties were the probability that the initially excited donor is excited at a time t after the excitation, Gs(t), the mean square displacement of the excitation and different fluorescence observables.

  6. 19. Aggregation of gluten proteins - from wheat seed biology to hydrogels : scientific modelling based primarily on Monte-Carlo and HPLC methods

    Author : Joel Markgren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Gluten proteins are intrinsically disordered proteins that form extensive aggregated networks in wheat seeds, where they are stored as a nutrient source for the embryo. A modelling approach involving computational biology with Monte-Carlo algorithms and wet laboratory studies, including HPLC analysis, was applied to unravel the aggregational and hydrogelforming properties of the gluten proteins.

  7. 20. Constellation Shaping in Optical Communication Systems

    Author : Ali Mirani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent receiver; constellation shaping; multidimensional modulation format; optical communications; probabilistic shaping; geometric shaping;

    Abstract : Exploiting the full-dimensional capacity of coherent optical communication systems is needed to overcome the increasing bandwidth demands of the future Internet. To achieve capacity, both coding and shaping gains are required, and they are, in principle, independent. READ MORE
