  1. 16. Mammalian thioredoxin reductase 1 in antioxidant defense, regulation of adipocyte differentiation and as an anticancer drug target

    Författare :Xiaoxiao Peng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Reactive oxygen species (ROS) are oxygen containing reactive molecules generated as by-products of cellular metabolism. At physiological concentrations, ROS acts as secondary messengers in cellular signaling transduction, but excessive amounts of ROS result in oxidative stress and cellular damage. LÄS MER

  2. 17. Protein Folding Simulations in Kink Model

    Författare :Xubiao Peng; Antti Niemi; Ulrich Hansmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; kink model; soliton; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : The structure of protein is essentially important for life activities. Proteins can perform their functions only by specific structures. In this thesis, the kink and multi-kink model for protein description are reviewed. LÄS MER

  3. 18. Identification, validation and clinical application of a three-gene signature for accurate prognosis prediction and treatment selection of newly diagnosed prostate cancer

    Författare :Zhuochun Peng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis presents a complete, comprehensive and stepwise approach of translational molecular research. Starting from whole-genome bioinformatics analyses based on the embryonic stem (ES) cell hypothesis, a three-gene signature was identified, validated with the goal of clinical application in order to optimize treatment decision based on improvement of overall survival estimation.

  5. 20. Iodine Isotopes (129I and 127I) in the Baltic Sea   : Tracer applications & environmental impact

    Författare :Peng Yi; Ala Aldahan; Glen Snyder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radioactive 129I; stable 127I; AMS; iodine species; nuclear reprocessing facilities; tracers; Baltic Sea; circulation; water exchange; environmental impact;

    Sammanfattning : 129I is a radioactive isotope (T1/2= 15.7 million years) produced through natural and anthropogenic pathways, but the anthropogenic production is presently dominating the Earth’s surface environments. LÄS MER
