Briefly, under pentobarbital anesthesia, 100 [micro]L of 1% OXN (4-ethoxymethylene-2-phenyl-2-oxazolin-5-one, Sigma-Aldrich, St.
TU-100 in distilled water was given orally at 900 mg/kg to colitis mice several hours, 1,2, and 3 d after OXN instillation.
Even though the accumulation feature is included in the OXN architecture, it involves a high fabrication cost to be developed because it is made from a flexible Bragg grating filter configuration and also a high number of circulators.
Like OXCs, OXNs also cannot perform the ring protection scheme.
Nitrogen transport was dominated by TKN (OrgN and ammonium) at all sites, with OxN generally making up <25%.
The focus of trapping in this buffer was between the upper and middle flumes (SS 36%, TN 40%, TKN 42%, OxN 32%, TP 52%).
