1. 16. Ready to pull : force transmission during vascular development

   Författare :Yuanyuan Zhang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The transmission of mechanical forces controls a multitude of cellular processes such as migration, the formation of new organs, muscle contraction, and resistance to the continuous stress that blood flow exerts on the blood vessel wall. These forces are sensed and replayed at the sites of cellular adhesion to the basal membrane as well as cell-cell junctions, where protein complexes connect to the cellular cytoskeleton to relay force into the cell.

3. 17. Nanowires for Cell Research

   Författare :Waldemar Hällström; Fasta tillståndets fysik; []
   Nyckelord :Nanotoxicology; Nanowires; Nanotubes; Nerve Cells; Cell Probing; Force Measurements; Nanotechnology; Axonal Guidance; Fysicumarkivet A:2010:Hällström;

   Sammanfattning : This study explores the interaction between living biological cells and semiconductor nanowires. Biological cells are highly complex and dynamic entities, every one of them with individual characteristics and a high degree of internal and external communication. LÄS MER

4. 18. The genetic mechanism that links Hutchinson-Gilford progeria syndrome to physiological aging

   Författare :Sofía Rodríguez Vásquez; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Aging is a complex process that is not completely understood. The study of segmental progeroid syndromes such as Hutchinson-Gilford progeria syndrome (HGPS) has allowed us to connect the common genetic mechanisms that occur in normal physiological aging, with the cellular alterations presented by this severe premature aging syndrome.

5. 19. The Pancreatic Tumour Microenvironment. Influence by macrophages and glucose levels on tumourigenesis

   Författare :Emelie Karnevi; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Pancreatic cancer is the fourth cause of cancer-related death with a 5-year survival rate less than 5%. Two of the risk factors are chronic pancreatitis and type 2 diabetes (T2D), which are believed to promote the tumour progression. LÄS MER

7. 20. QCM-D based biosensing – exploring the possibilities

   Författare :Erik Nilebäck; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell morphology; drug discovery; plasminogen; protein conformation; viscoelastisicity; QCM-D; oligo ethylene glycol ; Quartz crystal microbalance with dissipation monitoring; streptavidin;

   Sammanfattning : We are constantly increasing our understanding of all biological systems and how these highly complex systems interact with each other. The high degree of complexity of these systems can be investigated in greater and greater detail by increasingly sophisticated sensing techniques. LÄS MER
