  1. 11. Development of Nanocellulose Materials for Nano-filtration and Microfluidic Cell Culture

    Författare :Lulu Wu; Maria Tenje; Natalia Ferraz; Pasi Kallio; Margareta Krabbe; Lars Evenäs; Caroline Adiels; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; plasma-derived biologics; virus removal filtration; microfluidics; cell alignment; topography; shear stress.;

    Sammanfattning : Nanocellulose, cellulose nanofibrils or nanocrystals, is an interesting material for a wide range of applications. It can be obtained from abundant sources (higher plants, bacteria and algae), and presents many advantages to be used in the biomedical field such as biological safety, high surface area, porosity, and tailorable rheological properties.

  3. 12. Novel radiation targets in the endothelium and heart muscle

    Författare :Venkata Ramesh Yentrapalli; Siamak Haghdoost; William F. Morgan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; Endothelial cells; Senescence; Cardiovascular disease; Proteomics; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Worldwide, people are being exposed to natural and man-made sources of radiation. Epidemiological studies have shown an increased risk of vascular diseases in populations that have been exposed to ionizing radiation. Vascular endothelium is implicated as one of the targets for radiation leading to the development of cardiovascular diseases. LÄS MER

  4. 13. Group B streptococcal infections in neonates : Clinical and pathogenic aspects

    Författare :Jan Källman; Leif Gothefors; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Clinical and pathogenic aspects of Group B streptococci (GBS), as a major pathogen responsible of invasive disease in newborn infants, were investigated.Cases of neonatal septicaemia during 1981-1994 were studied at Orebro Medical Centre Hospital. 132 children ful1filled laboratory and clinical criteria for neonatal septicaemia.

  5. 14. Development of a New Biomechanical ex vivo Perfusion System - Studies on effects of biomechanical and inflammatory stress on hemostatic genes in human vascular endothelium

    Författare :Niklas Bergh; Göteborgs universitet; []
    Nyckelord :ex vivo perfusion system; biomechanical; endothelium; shear stress; tensile stress; pulsatile; TNF-α; JNK; hemostatic genes;

    Sammanfattning : The vascular endothelium is a multifunctional interface constantly exposed to biomechanical forces such as shear and tensile stress. Biomechanical stress is involved in the pathophysiological process of the vessel wall and thus affects vascular remodeling, atherosclerosis and thrombogenesis. LÄS MER

  7. 15. Host cell adhesion of Plasmodium falciparum-infected erythrocytes

    Författare :Carl Johan Treutiger; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Plasmodium falciparum; erythrocyte rosetting; cytoadherence; cerebral malaria; PfEMPI; serum proteins; PECAM-I CD31;

    Sammanfattning : Excessive binding of Plasmodium falciparum-infected erythrocytes to the microvascular endothelium (cytoadherence) and to uninfected eryrthrocytes (rosetting) are regarded as key-events in the development of a severe malaria infection. P. falciparum rosetting was confirmed to be associated with the development of cerebral malaria in The Gambia. LÄS MER
