1. 16. Fish Lenses : Anatomy and Optics

   Författare :Tomasz M Kozłowski; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasticity; Development; Cellular structure; Lens fiber cells; Modeling; Laser Scanning; Schlieren photography; Fast Fourier Transform FFT ;

   Sammanfattning : I have investigated some of the biological regulatory mechanisms governing the development of crystalline lenses. I used fish as model animals because they possess optically interesting lenses, while the geometrical simplicity of fish lenses allows for studies that are difficult or impossible with the lenses of other animals.

3. 17. Artificial blood vessels - Studies on endothelial cell and blood interactions with bacterial cellulose

   Författare :Helen Fink; Göteborgs universitet; []
   Nyckelord :bacterial cellulose; endothelial cells; thrombogenicity; xyloglucan; contact activation; imaging of coagulation; vascular grafts; RGD; cell adhesion; bioreactor; xyloglucan;

   Sammanfattning : Cardiovascular diseases are still the number one cause of death or invalidity in the western world today. Atherosclerotic plaques and restenosis can result in severe occlusions of peripheral and coronary arteries. Treatment depends on the severity of the disease and includes drug therapy and bypass surgery. LÄS MER

4. 18. Computational modelling in systems biology: from rewriting cell fates to detecting tumours

   Författare :Emil Andersson; Centrum för miljö- och klimatvetenskap (CEC); []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Beräkningsmodeller; Systembiologi; Genreguleringsnätverk; Cellomprogrammering; Energilandskap; iPSC; Agentbaserad modellering; T-cellsutveckling; Maskininlärning; Tumördiagnostik; Computational modelling; Systems biology; Gene regulatory network; Cell reprogramming; Energy landscape; iPSC; Agent-based modelling; Multi-scale modelling; T-cell development; Machine learning; Tumour diagnostics;

   Sammanfattning : Computational modelling is becoming an increasingly important tool in biological research. By performing computer simulations of models, it becomes possible to test theories about a biological system against experimental data. Simulations can also be used as a replacement for experiments otherwise unattainable. LÄS MER

5. 19. Single cell studies of natural killer cell immune surveillance

   Författare :Elin Forslund; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Our immune system protects us from microbes such as viruses, bacteria and parasitic worms. The immune system also plays a key role in fighting cancer and in carrying out a function termed ‘immune surveillance’, natural killer (NK) cells patrol tissues and participate in the elimination of transformed cells and established tumors.

7. 20. Stem cell transplantation and regeneration after dorsal root avulsion

   Författare :Carl Trolle; Elena Kozlova; Adam Reid; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regeneration; dorsal root; sensory nerve; nerve injury; cell transplantation; Medical Science; Medicinsk vetenskap;

   Sammanfattning : Spinal root avulsion leads to paralysis and loss of sensory function. Surgical methods can improve motor function and ameliorate pain but sensory recovery in adults is poor. Previous studies have shown that cell transplantation or treatment with trophic factors can improve functional outcome in rodents after dorsal root transection or crush. LÄS MER
