  1. 41. Injectable Composite Hydrogels Based on Metal-Ligand Assembly for Biomedical Applications

    Författare :Liyang Shi; Jöns Hilborn; Dmitri Ossipov; Wenxin Wang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; injectable; hydrogel; shear-thinning; self-healing; coordination chemistry; biomedical applications;

    Sammanfattning : This thesis presents new strategies to construct injectable hydrogels and their various biomedical applications, such as 3D printing, regenerative medicine and drug delivery. These hydrogels cross-linked by dynamic metal-ligand coordination bonds exhibit shear-thinning and self-healing properties, resulting in the unlimited time window for injection. LÄS MER

  3. 42. Pursuing the fever trail : pathogenesis of blood-stage P. falciparum malaria and pregnancy

    Författare :Niloofar Rasti; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Plasmodium falciparum; malaria; erythrocytes; pregnancy; Uganda; placental sequestration; cytoadhesion; PfEMP1; var2csa; antigenic variation; live-cell proteomic.;

    Sammanfattning : The burden of the most virulent form of human malarias, Plasmodium falciparum, is concentrated among young children and pregnant women in sub-Saharan Africa. Excessive sequestration of parasite-infected red blood cells (pRBCs) in the capillary beds of different organs is the hallmark of P. LÄS MER

  4. 43. Surface Modification of Cellulose-based Materials for Tailoring of Interfacial Interactions

    Författare :Simon Utsel; Lars Wågberg; Simon Biggs; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The awareness of our need for a sustainable society has encouraged the search for renewable, high quality materials that can replace oil-based products. This, in combination with increased competition in the forest industry, has stimulated a lot of research into different types of wood-based materials where cellulose-rich fibers are combined with different types of polymers.

  5. 44. Human spinal cord models for development of spinal cord injury repair strategies

    Författare :Chenhong Lin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : There is still no available cure for human spinal cord injury (SCI). After a SCI, neural cell loss, excitotoxicity, neuroinflammation, astrocytic and oligodendrocytic derived inhibiting factors contribute to a non-permissive spinal cord environment hindering neuroregeneration with little, if any, endogeneous functional improvement.

  7. 45. Modular Enzyme-Responsive Polysaccharide-Based Hydrogels for Biofabrication

    Författare :Sajjad Naeimipour; Daniel Aili; Robert Selegård; Alireza Dolatshahi-Pirouz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D cell-culture; Bioprinting; Alginate; Hyaluronan; Cancer model;

    Sammanfattning : Engineered human tissue and disease models can decrease the cost and time of developing new drugs and treatments, facilitate personalized medicine, and eliminate the need for animal models that poorly represent the human body and are ethically problematic. However, the current conventional cell expansion methods using 2D culture flasks cannot enable the development of such complex multi-cellular 3D models. LÄS MER
