To compare the accuracy of a navigation system for oral implantology using either a head-mounted display (HMD) or a monitor as a device for visualization. Drilling experiments in plastic mandibles were performed by seven investigators supported by a navigation system using an HMD. A set of drilling experiments was carried out using a traditional monitor(More)
Desmosomes provide intercellular adhesive strength required for integrity of epithelial and some non-epithelial tissues. Within the epidermis, the cadherin-type adhesion molecules desmoglein (Dsg) 1-4 and desmocollin (Dsc) 1-3 build the adhesive core of desmosomes. In keratinocytes, several isoforms of these proteins are co-expressed. However, the(More)
BACKGROUND The intestinal epithelium of patients with Crohn's disease (CD) is characterized by defects in permeability and alterations in tight junction morphology sealing the paracellular cleft. Desmosomes are primarily considered to mediate strong intercellular cohesion. Because barrier properties of epithelial cells were shown to depend on the function(More)
