In comparison, gap density averaged 1 per 192 ha on the surrounding highlands (elevation >700 m) of high relief and soils with low clay content.
The electronic properties of the adsorbed system were investigated, including band gap, density of states, work function, the highest occupied molecular orbital and the lowest unoccupied molecular orbital.
For example, temperature is 3 4°C higher in canopy gaps [27] and a sufficient increase in gap density can also increase the temperature of the forest as a whole [6], [28] [29].
The median follow-up for patients with elevated gap density was longer than that for patients with normal gap density (13 vs. 17 months, P=0.02).
The clinical significance of the increased epithelial gap density will need further investigation.
There was no correlation between anti-TNF therapy initiation and epithelial gap density (P=0.28).
Thus, determining epithelial gap density for IBD patients with CLE may have diagnostic and prognostic values.
The correlation of gap density with endoscopic location and severity of disease was also studied.
Gap density was a significant predictor for risk of major events, with a hazard ratio of 1.10 (95% confidence interval=1.01, 1.20) associated with each increase of 1% in gap density.
Interestingly, the endoscopic location of disease did not correlate with gap density in Crohn's patients, that is, patients with ileitis did not have elevated gap density in normal-appearing areas of the terminal ileum.
Patients with normal gap density were found to be at lower risk for events (hospitalization or surgery) than those with elevated gap density (P=0.02 from log-rank test) during the follow-up period, shown in Figure 1.
