  2. 1. Thermodynamic and kinetic investigation of systems related to lightweight steels

    Author : Weisen Zheng; Malin Selleby; Tomás Gómez-Acebo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-Mn-Al-C; CALPHAD; MGI; ICME; Precipitation strengthening; Lightweight steels.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Lightweight steels have attracted considerable interest for automobile applications due to the weight reduction without loss of high strength and with retained excellent plasticity. In austenitic Fe-Mn-Al-C steels, the nano-precipitation of the κ-carbide within the austenitic matrix significantly contributes to the increase in yield strength. READ MORE

  4. 2. Regulation of HPV16 Early Gene Expression

    Author : Yunji Zheng; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV16; splicing; mRNA; hnRNP A1; hnRNP G; E6; E7; E1; E2;

    Abstract : Human papillomavirus type 16 (HPV16) is the most common high-risk type and isassociated with more than 50% cervical cancer cases as well as a number of headand neck cancer cases. The life cycle of HPV16 is strictly linked to celldifferentiation in the squamous epithelium with expression of the HPV16 earlygenes. READ MORE

  5. 3. Regulation of cellular responses to hypoxia by HIF-1alpha-dependent and -independent signaling pathways

    Author : Xiaofeng Zheng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hypoxia is a state of inadequate oxygen supply to the cells and tissues of the body. It plays a critical role in embryonic development, as well as in various physiological and pathological processes. READ MORE

  6. 4. Oxygen-dependent regulation of HIF-1alpha expression and function

    Author : Xiaowei Zheng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Hypoxia is a state of reduced oxygen levels below normal values. It occurs in the pathophysiology of many diseases and plays important roles in mammalian physiology and development. The hypoxia-inducible factors (HIFs) are transcription factors that mediate adaptive cellular responses to hypoxia by activating the transcription of target genes. READ MORE

  7. 5. Isolation and characterization of novel intestinal polypeptides of the enteroinsular and brain-gut axes and of macrophages

    Author : Zheng-wang Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The gastrointestinal tract has been recognized as our largest endocrine organ, from which many peptide hormones, neuropeptides and growth factors have been isolated. There is also increasing evidence that the gastrointestinal tract can be considered as our largest immune organ, from which many antibacterial peptides, cytokines, cytotoxins and chemokines have been characterized.
