  1. 26. Mammographic density in relation to breast cancer Tumor characteristics, mode of detection, and density assessments

    Författare :Hanna Sartor; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Mammographic density reflects the composition of the breast tissue and can be measured by different methods. Mammography has a lower sensitivity in women with dense breasts, and women with dense breasts have a higher incidence of breast cancer than do women with non–dense breasts. LÄS MER

  3. 27. Studies on bacteria resistant and susceptible to humoral immunity in insects

    Författare :Inga Sidén; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Insects have developed several defense mechanisms against microorganismsi The injection of live bacteria into Lepidoptera pupae induces the synthesis of several bactericidal proteins, especially the cecropins and the attacins. Important properties of an insect pathogenic bacterium are invasiveness and resistance to immunity. LÄS MER

  4. 28. Collagen-binding integrin α2β1 activity in vivo and in vitro : Effects of platelet-derived growth factor-BB

    Författare :Karina Åhlén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Integrin α2β1; PDGF-BB; fibroblast; interstitial fluid pressure; cytoskeletal interaction; phosphatidylinositol 3-kinase; [Ca2 ]i; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : The expression of integrins by two cell clones from a rat colon carcinoma was investigated. Cloned cells that gave rise to regressive tumors, but not cells that gave rise to progressive, lethal, tumors, adhered to interstitial collagens through the integrin α2β1, although both cell types expressed it.

  5. 29. Graphene Implementation Study in Semiconductor Processing

    Författare :Patrik Ahlberg; Zhibin Zhang; Shi-Li Zhang; Ulf Jansson; Eleanor Campbell; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Graphene, with its two-dimensional nature and unique properties, has for over a decade captured enormous interests in both industry and academia. This work tries to answer the question of what would happen to graphene when it is subjected to various processing conditions and how this would affect the graphene functionality. LÄS MER

  7. 30. Oxidoreductases and RNA degradosome controlling virulence-associated traits of Salmonella enterica serovar Typhimurium

    Författare :Naeem Anwar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The oxidative stress response is a fundamental and primitive mode of innate immune defense in nearly all forms of life. The host oxidative stress response becomes truly important and effective especially against intracellular pathogens such as Salmonella. Pathogens have evolved diverse mechanisms to withstand the oxidative responses. LÄS MER
