  2. 1. Human 15-lipoxygenase-1 and telomerase gene expression in cancer and inflammation

    Author : Cheng Liu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Human 15-lipoxygenase type 1 (15-LOX-1) is an enzyme that catalyzes the oxygenation of free or membrane-bond polyunsaturated fatty acids containing at least one bis-allylic methylene moiety. The enzyme has been proposed to be involved in various physiological and pathophysiological activities including inflammation, apoptosis, cell maturation and tumorigenesis. READ MORE

  4. 2. The nature of stars with a common origin: clues from metallicity, elemental abundances, and kinematics

    Author : Cheng Liu; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stars: abundances; Galaxy: evolution; Galaxy: solar neighbourhood; Galaxy: bulge; Galaxy: globular clusters;

    Abstract : Most of field stars originate from dissolved star clusters. If the gas cloud is well mixed the stars in the cluster are expected to be chemically homogenous. READ MORE

    Abstract : Additive manufacturing (AM), also known as 3D printing, is a concept and method of a manufacturing process that builds a three-dimensional object layer-by-layer. Opposite to the conventional subtractive manufacturing, it conquers various limitations on component design freedom and raises interest in various fields, including aerospace, automotive and medical applications.
