  1. 41. Cyclins on the move : a time and a place for cyclin A2 and cyclin B1 in the human cell cycle

    Författare :Helena Silva Cascales; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The ultimate aim of the cell cycle is to create an identical daughter cell. Therefore, correct progression through the different phases of the cell cycle is crucial to ensure faithful cell division. LÄS MER

  3. 42. In vivo analysis of amino acid permease folding in yeast

    Författare :Andreas Ring; Per O. Ljungdahl; George Diallinas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; endoprotease; subcellular fractionation; membrane-localized chaperone; amino acid permease; endoplasmic reticulum; membrane protein folding; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Sammanfattning : Plasma membrane (PM) proteins are critical for cells to respond to environmental cues, such as the availability of nutrients. The yeast Saccharomyces cerevisiae is able to sense extracellular amino acids using the SPS sensing system. LÄS MER

  4. 43. Thymic Stroma and T Cell Development. Impacts of Retinoic Acid Signaling

    Författare :Kerstin Wendland; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thymus; Thymic epithelial cells; Retinoic acid; T cell development; Stromal Cells;

    Sammanfattning : The development of functionally competent, self-tolerant T cells in the thymus is an essential prerequisite for the formation of adaptive immune responses against foreign pathogens. Thymic epithelial cells (TECs) form specialized stromal microenvironments in the cortex (cTEC) and medulla (mTEC) of the thymus that support all stages of T cell development, from the entry of thymocyte progenitors to the exit of mature naive T cells.

  5. 44. HealthyMoms : a smartphone application to promote healthy weight gain, diet and physical activity during pregnancy : a randomized controlled trial

    Författare :Johanna Sandborg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The prevalence of overweight and obesity is a major public health concern, also among pregnant women. Alarmingly, around half of pregnant women in high income countries exceed the recommendations for an optimal gestational weight gain (GWG). LÄS MER

  7. 45. Evaluation of absorbed dose and image quality in mammography

    Författare :Bengt Hemdal; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optically stimulated luminescence; radioluminescence; in vivo dosimetry; dose reduction; dose protocol; average glandular dose; absorbed dose; Breast cancer; mammography; Monte Carlo; image quality; image quality criteria; contrast-detail phantom;

    Sammanfattning : Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. LÄS MER
