  2. 16. A study of the foveal structure in prematurely born children by the use of optical coherence tomography

    Author : Rebecka Rosén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : During the last decades there has been a rapid development in techniques for retinal imaging. The optical coherence tomography (OCT) examination is non-invasive, fast and patient-friendly which are good qualities when examining children. There is a steadily increasing survival rate of extremely premature infants due to improved neonatal care. READ MORE

  4. 17. Characterization of regulatory factors controlling tip growth in Nicotiana tabacum pollen tubes

    Author : Jia Sun; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Rho GTPases constitute a family of highly conserved signaling proteins with key functions in the regulation of cellular polarization and polar cell growth. In plants, Rho GTPases are represented by a plant specific subfamily referred to as Rac/Rop GTPases. READ MORE

  5. 18. Surface Modification of Cellulose by Covalent Grafting and Physical Adsorption for Biocomposite Applications

    Author : Carl Bruce; Eva Malmström; Anna Carlmark; Linda Fogelström; Youssef Habibi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

    Abstract : There is an increasing interest to replace fossil-based materials with renewable alternatives. Cellulose fibers/nanofibrils (CNF) are sustainable options since they are biobased and biodegradable. In addition, they combine low weight with high strength; making them suitable to, for example, reinforce composites. READ MORE

  6. 19. Levulinic Acid : Versatile Building Block for Plasticizer Design

    Author : Wenxiang Xuan; Minna Hakkarainen; Karin Odelius; Rafael Auras; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; levulinic acid; plasticizer; polylactide; migration; degradation; antibacterial;

    Abstract : The utilization of renewable resources is a challenging and an importantaspect towards development of sustainable plastic products. Therefore,commercial biomass conversion to produce biobased chemicals isnecessary to replace current fossil-based chemicals. READ MORE

  7. 20. Structure and Function of the Retina in Children Born Extremely Preterm and in Children Born At Term

    Author : Anna Molnar; Gerd E. Holmström; Eva K. B. Larsson; Sten O. Andréasson; Christopher J. Lyons; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optical coherence tomography; multifocal electroretinogram; full-field electroretinography; extremely preterm children; retinopathy of prematurity; gestational age; gender; Ophtalmology; Oftalmiatrik;

    Abstract : Background: Optical coherence tomography (OCT), multifocal electroretinography (mfERG) and full-field electroretinography (ffERG) give important information about retinal structure and function.Purpose: To collect normative data of macular Cirrus Spectral domain (SD)-OCT assessments and of mfERG measurements of healthy children (papers I and II).
