  1. 1. On the binding of growth-promoting polyamines to proteoglycans: Implications for growth-regulation and polycation-mediated gene transfer

    University dissertation from Department of Cell and Molecular Biology, Lund University

    Author : Mattias Belting; Lund University.; Lunds universitet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; cationic lipid.; gene transfer; gene therapy; cell growth; polyamine transport; spermine; polyamine; growth-inhibition; heparan sulphate; dermatan sulphate; Proteoglycan; glycosaminoglycan; cytogenetics; Genetik; cytogenetik;

    Abstract : Initial investigations were directed at studying the interaction between polyamines and various glycosaminoglycans (GAGs). The polyamine spermine displayed binding to dermatan sulphate (DS) and heparan sulphate (HS) with similar (Kd, 3.9 x 10-4 M) and higher (Kd, 0.37 x 10-6 M) affinity, respectively, than to DNA.

  2. 2. Fermentation of Lignocellulosic Hydrolysates: Inhibition and Detoxification

    University dissertation from Department of Applied Microbiology, Lund University

    Author : Eva Palmqvist; Lund University.; Lunds universitet.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation strategies; mechanisms; identification; inhibition; lignocellulosic hydrolysates; Ethanol; Saccharomyces cerevisiae; virology; virologi; mykologi; mycology; Mikrobiologi; bakteriologi; bacteriology; Microbiology;

    Abstract : The ethanol yield and productivity obtained during fermentation of lignocellulosic hydrolysates is decreased due to the presence of inhibiting compounds, such as weak acids, furans and phenolic compounds produced during hydrolysis. Evaluation of the effect of various biological, physical and chemical detoxification treatments by fermentation assays using Saccharomyces cerevisiae was used to characterise inhibitors. READ MORE

  3. 3. Mesenchymal Stem Cells in Tumor Growth Inhibition and Cartilage Differentiation

    University dissertation from Department of Experimental Medical Science, Lund Univeristy

    Author : Laura Varas; Lund University.; Lunds universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper; Medicine human and vertebrates ; Medicin människa och djur ; mesenchymal stem cell; Biomedical sciences; tumor growth inhibition; FGF2; cartilage; integrin alpha11beta1; integrin alpha10beta1;

    Abstract : The work presented in this thesis has been focused on mesenchymal stem cells (MSCs). In the two first studies, the effects of MSCs on tumor growth and development in vitro and in vivo was investigated. READ MORE

  4. 4. Growth control mechanisms in normal and neoplastic mammalian cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mozhgan Afrakhte; Uppsala universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; PDGF-AA; TGF-beta; Inhibitory SMADs; Growth inhibition; CDK; CKI; Cdc25A; Genetik; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik; Genetics; genetik;

    Abstract : The main theme of the studies presented in this thesis is, the growth control mechanisms whose loss in normal cells predispose to or cause cancer. The balance between growth inhibitory and stimulatory mechanisms is crucial for the development and maintenance of a normal animal. READ MORE

  5. 5. Too close for comfort The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Marcus Wäneskog; Sanna Koskiniemi; Paul Rainey; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial interactions; cell-cell binding; contact-dependent growth inhibition; CDI; CdiB; CdiA; CdiI; outer-membrane receptor; BamA; OmpC; OmpF; extracellular toxin delivery; Toxin-Antitoxin; TA-system; persister cells; stress tolerance; stress response; rpoS; rssB; quorum sensing; multicellular behavior; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. READ MORE
