We introduced piperidine to increase sheet resistance gaps between conductive and insulating region.
Due to its locking configuration, the suture tightens around the collagen fibers when tensile forces are applied, thus providing approximation under tension, greater ultimate tensile strength, and resistance to gapping (Becker and Davidoff 1977; Hatanaka et al. 2000).
In this case, the interrupted horizontal mattress technique proved to be significantly more effective in regards to ultimate tensile strength and resistance to gapping.
The majority of gain-of-function mutations affecting RAS proteins, including those contributing to oncogenesis, trigger the accumulation of these GTPases in the active state by impairing intrinsic GTPase activity, and/or conferring resistance to GAPs (17).
Demonstrating the importance of suture technique, a bovine model showed that the triple-strand technique provided greater mean peak load to failure, and greater resistance to gapping when compared with Dresden, Krackow, and modified oblique Dresden techniques (Fig. 3).
This duplication has been shown to induce cellular transformation in vitro and activation of the RAS MAPK signalling pathway linked to impaired intrinsic GTP hydrolysis and resistance to GAPs (Bollag et al, 1996).
A point mutation, in the hot spot region, leading to an amino acid substitution will decrease the intrinsic GTPase activity of Ras and also confer resistance to GAPs 7. Therefore, GTP-bound Ras will accumulate, rendering the MAPK pathway constitutively activated.
Special methods were developed to determine the convective and air gap resistances, with the membrane resistance obtained by subtracting such two resistances from the total resistance.
There was no association between gap resistance and fatigue strength.
Reducing the gap resistance by increasing gap conductance (conductive gap MD (CGMD)), leads to an increase in ε through an increase in NTU, and only a small decrease in η, resulting in about two times higher overall GOR.
