In conical fit abutments, the collar of the abutment sits inside the implant which allows a stronger junction between implant and abutment and a better seal against bacteria into the implant body.
The gelation of the present polymers is presumed to be attributed to the intermolecular interaction between the hydrophobic oligopeptide side groups, which can form strong physical junction zones in the polymer aqueous solution.
Transmission electron microscopy (TEM) analysis confirmed that cells within the hybrid-spheroid formed strong cell junctions and contacts with fragmented fibers.
Sheets of epithelial cells are held together tightly at strong adherens junctions containing E-cadherin in complexes with catenins linked to the actin cytoskeleton.
The BBB is formed by specialised capillary endothelial cells, which have several properties, such as strong tight junctions with a high electrical resistance, absence of fenestrations and presence of efflux-pumps such P-glycoprotein (P-gp) and multidrug resistance associated protein 1 (MRP1).
Staining was particularly strong at the junction between the enamel and dentine (Fig. 5A).
The cross-linking reaction occurs within the nanofibers as well as between the nanofibers that are in touch, forming relatively strong inter-fiber junctions and hence resulting in remarkable improvement in structural integrity of the electrospun mats with very small thickness.
It is the largest, thickest and, crucially, the strongest of the craniocervical junction ligaments (and, in fact, the strongest ligament in the entire spine) and, therefore, a primary stabiliser of the craniocervical junction.
In principle, this top cell could be replaced by a PEC junction with strong absorption in a similar range to form a water-splitting photoelectrode for hydrogen production.
If the junction is strong, as is the case with certain (3,3 - 3,3 3,3 - 3,3s, then the bonds break at individual nanotubes, rather than at the junctionsregion, and thenoriginal bonding sthectures around the junctions remain.
