  2. 16. Elicitor-induced formation of secondary products in plant cell cultures. Production of benzophenanthridine alkaloids in Eschscholtzia californica Cham. and hydroxycinnamic acid tyramides in Nicotiana glutinosa L

    Author : Mirza Villegas; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; macarpine; chelerythrine; sanguinarine; benzophenanthridine alkaloids; Nicotiana glutinosa; Eschscholtzia californica; secondary metabolites; Key words elicitors; immobilisation; hydroxycinnamoyltyramides.; Plant biochemistry; Växtbiokemi;

    Abstract : Biotic and abiotic elicitors induce biosynthesis of secondary metabolites (phytoalexins) as a defense against pathogenic organisms in plants. The use of cell suspension cultures in combination with elicitors offer excellent experimental model systems for studies on various elicitor-induced responses of plant tissues. READ MORE

  4. 17. Development of biosynthetic conduits for peripheral nerve repair

    Author : Aleksandra McGrath; Liudmila N Novikova; John Haycock; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthetic conduit; Mesenchymal stem cells; Nerve graft; Nerve tissue engineering; Peripheral nerve injury; Schwann cells;

    Abstract : Peripheral nerve injuries are often associated with significant loss of nervous tissue leading to poor restoration of function following repair of injured nerves. Although the injury gap could be bridged by autologous nerve graft, the limited access to donor material and additional morbidity such as loss of sensation and scarring have prompted a search for biosynthetic nerve transplants.

  5. 18. Concepts for improving ethanol productivity from lignocellulosic materials : encapsulated yeast and membrane bioreactors

    Author : Päivi Ylitervo; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulated yeast; Biofuel; S. cerevisiae; Membrane bioreactors; Thermotolerance; Furfural; Acetic acid; Resource Recovery; Resursåtervinning; Resource Recovery;

    Abstract : Lignocellulosic biomass is a potential feedstock for production of sugars, which can be fermented into ethanol. The work presented in this thesis proposes some solutions to overcome problems with suboptimal process performance due to elevated cultivation temperatures and inhibitors present during ethanol production from lignocellulosic materials.

  6. 19. 3D Printed scaffolds as cancer microenvironment medels for drug discovery

    Author : Jennifer Rosendahl; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D Printing; Breast cancer; Biomaterials; Drug development;

    Abstract : Cancer is one of the most common diseases in the modern world and major efforts are made globally to develop new diagnostics and treatments. It originates from a cell which, at some point, has begun to divide and grow uncontrollably. The most common type is breast cancer, and like all other cancers there is a need of more efficient drug therapies. READ MORE

  7. 20. Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

    Author : Danfeng Cao; Edwin Jager; Jose Gabriel Martinez Gil; Jonathan Rossiter; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The human body is a complex system, consisting of different types of biomolecules and living matters, such as nucleic acids, proteins, carbohydrates, lipids, serum, cells, tissues, and organs. These complex biomolecules and living matters integrate and interact dynamically to perform and maintain body functions. READ MORE
