    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCD Programmed Cell Death ; Xylem; Apoptosis; Autophagy; Secondary Cell Walls; Microscopy; Microarrays; Comet Assay; TUNEL Assay; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi;

    Abstract : Concerns about climate changes and scarcity of fossil fuels are rising. Hence wood is becoming an attractive source of renewable energy and raw material and these new dimensions have prompted increasing interest in wood formation in trees, in both the scientific community and wider public.

  2. 2. Function of MAP20 and MYB103 in cellulose and lignin formation of xylem secondary cell walls

    University dissertation from Plant Physiology Department - Umeå Plant Science Centre

    Author : David Öhman; Sveriges lantbruksuniversitet.; [2014]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Lignocellulose from trees and other crops will have tremendous impact on the next generation of sustainable biofuels and biomaterials. To take advantage of modern breeding tools, it is therefore important to understand the genetic and molecular regulation underlying secondary cell wall formation. READ MORE

  3. 3. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites

    University dissertation from Plant Physiology Department - Umeå Plant Science Centre

    Author : Jasna Stevanic Srndovic; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic FTIR spectroscopy; viscoelasticity; orientation; Norway spruce; protein; glucomannan; xyloglucan; polymer interactions; pectin; imaging FTIR microscopy; primary cell wall; nanocomposite films; dynamic 2D FTIR spectroscopy; xylan; wood fibre; cellulose; secondary cell wall; DMA; lignin;

    Abstract : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

  4. 4. Stem cell based therapy of malignant brain tumors

    University dissertation from Avd för Neurokirurgi, Inst för kliniska vetenskaper, Medicinska fakulteten, Lunds Universitet

    Author : Daniel Bexell; Lunds universitet.; Lund University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; pericyte; mesenchymal stem cell; neuroblast; subventricular zone; cancer stem cell; rat; glioma; cancer;

    Abstract : Malignant brain tumor is a highly invasive and vascularized cancer. Current forms of therapy are not curative and can, at best, prolong survival for patients with this disease. The mean survival is only around 15 months. READ MORE

  5. 5. Coiled coil cytoskeleton in cell architecture and osmotic stress response in Streptomyces

    University dissertation from Department of Biology, Lund University

    Author : Katsuya Fuchino; Lunds universitet.; Lund University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coiled coil protein; Streptomyces coelicolor; polar growth; osmotic-stress response; turgor;

    Abstract : Popular Abstract in English Antonie van Leeuwenhoek is known as the father of microbiology, because he made the first microscopic observation of bacteria in human history, published in 1683. For the naked human eyes, bacterial cells are too small to observe, and the development of microscopy techniques has since then been fundamental for examining bacterial cells. READ MORE
