1. 3D super-resolution microscopy of living cells using reversibly switchable fluorophores
Sammanfattning : Traditional optical microscopy techniques are limited in spatial resolution due to the wave nature of light. This means that neighboring objects separated by a distance smaller than about 200 nm cannot be distinguished. LÄS MER
2. Quantitative chemical imaging to study content release from single nanovesicles
Sammanfattning : Cellular communication is vital for the survival of multicellular organisms. This process often relies on a highly regulated mechanism called exocytosis, which involves the release of chemical signals. During exocytosis, vesicles can fully or partially release their contents.

3. Biological effects of glucose degradation products in peritoneal dialysis fluids
Sammanfattning : Background: It is well known that Peritoneal dialysis (PD) fluids have biological effects on a number of cells and tissues in the peritoneum and the peritoneal cavity. However, little attention has been paid to the influence of glucose degradation products (GDPs), formed during heat-sterilization and storage of PD fluids. LÄS MER
4. Nanofluidics for Static and Dynamic DNA-Protein Interaction Studies - Repair of Double-Strand Breaks from a Single-Molecule Perspective
Sammanfattning : Double-strand breaks (DSBs) is one of the most lethal forms of DNA damage. A single DSB may result in stalling of vital cellular machineries, and thus, requires immediate measures by the cell. LÄS MER
5. Gastrointestinal mucosal protective mechanisms : Mudolatory effects of Heliobacter pyroli on the gastric mucus gel barrier and mucosal blood flow in vivo
Sammanfattning : The gastrointestinal mucus gel layer and blood flow are two important mechanisms for protection at the pre-epithelial and sub-epithelial levels, respectively. Helicobacter pylori might circumvent these mechanisms and elicit a chronic inflammatory response with consequent ulcers in the stomach and duodenum. LÄS MER
