16. Stiffness and aneurysm of the aorta. Relations to vascular aging, hyperglycemia, and inflammation
Sammanfattning : A well-functioning arterial system for the transport of oxygen to the cells is essential for human health. The aorta has a key role for the provision of this physiological effect. Disturbances to aortic function can lead to majorsymptoms and even death due to ruptured abdominal aortic aneurysm (AAA). LÄS MER
17. Lumbar disc herniation. Clinical outcome and segmental stability using a new radiological classification and radiostereometry
Sammanfattning : Satisfactory results following conventional lumbar discectomy have been reported in 70-90% of cases. Remaining or recurrent low back pain or sciatica is, however, seen in many patients for reasons not yet fully understood. A relationship has previously been shown between the morphologic characteristics, i.e. LÄS MER
18. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties
Sammanfattning : Incorporation of carbon nanotubes (CNT) into polymers is attractive due to the generally good processability of polymers and unprecedented properties of nanotubes. In this work, preparation and matrix known earlier but not employed so-far for nanocomposites are studied towards enhanced mechanical and electrical performances. LÄS MER
19. Nanocellulose-based materials: from colloidal assembly to functional films
Sammanfattning : The assembly of nature-based nanomaterials into complex architectures is both a design principle of biological composites, e.g., wood and nacre with outstanding properties and a promising route for developing functional macroscopic materials. LÄS MER
20. Hydrogels of Poly(vinyl alcohol) and Nanocellulose for Ophthalmic Applications : Synthesis, Characterization, Biocompatibility and Drug Delivery Studies
Sammanfattning : Hydrogels are commonly used materials in ophthalmic care as contact lenses, bandage lenses, corneal implants, and cornea regeneration scaffolds. Hydrogels can be produced by physical, chemical, or radiation crosslinking of hydrophilic polymers. LÄS MER
