Inflammation in areas of fibrosis (i-IFTA) in posttransplant biopsies is part of the diagnostic criteria for chronic active TCMR (CA TCMR -- i-IFTA >= 2, ti >= 2, t >= 2). We evaluated i-IFTA and CA TCMR in the DeKAF indication biopsy cohorts: prospective (n = 585, mean time to biopsy = 1.7 years); cross-sectional (n = 458, mean time to biopsy = 7.8 years). Grouped by i-IFTA scores, the 3-year postbiopsy DC-GS is similar across cohorts. Although a previous acute rejection episode (AR) was more common in those with i-IFTA on biopsy, the majority of those with i-IFTA had not had previous AR. There was no association between type of previous AR (AMR, TCMR) and presence of i-IFTA. In both cohorts, i-IFTA was associated with markers of both cellular (increased Banff i, t, ti) and humoral (increased g, ptc, C4d, DSA) activity. Biopsies with i-IFTA = 1 and i-IFTA >= 2 with concurrent t >= 2 and ti >= 2 had similar DC-GS. These results suggest that (a) i-IFTA >= 1 should be considered a threshold for diagnoses incorporating i-IFTA, ti, and t; (b) given that i-IFTA >= 2,t >= 2, ti >= 2 can occur in the absence of preceding TCMR and that the component histologic scores (i-IFTA,t,ti) each indicate an acute change (albeit i-IFTA on the nonspecific background of IFTA), the diagnostic category "CA TCMR" should be reconsidered.

Electrospun polypropylene fibrous (PPF) membrane was selected as a substrate to graft ionic liquids (ILs) and avoid tedious ILs separation and recovery. A catalytic membrane, BILs-g-PPF, was prepared by long-distance and dynamic low-temperature Ar plasma flow activation and subsequent grafting with dual -SO3H imidazole Bronsted acidic ILs (BILs), [(CH2)(3)SO(3)HVIm]HSO4. A novel multistage membrane series reactor was first developed by employing the BILs-g-PPF membrane to catalyze esterification of acetic acid with ethyl alcohol. The BILs, which supplied strong active H+ and benefited to overcome the chemical equilibrium due to its high hydrophilic groups, was chosen as a catalyst. The three-dimensional porous network architecture of PPF membrane provided a high specific surface area to graft considerable BILs and enhanced mass transfer in membrane. The optimization of reaction conditions was studied and the results were as followed: BILs grafting degree of 213.5 mol/m(3), reaction temperature 70 degrees C, molar ratio of acid to alcohol 1:5, membrane flux of 21.36 L/(m(2).h). In single-stage catalytic membrane system, the acid conversion achieved 66.24% in 8 h. The multistage membrane series reactor can improve the reaction conversion efficiency. For the used membrane which lost some anions, its catalytic properties could be largely restored by soaking activation using a dilute sulfuric acid aqueous solution with a mass concentration of 10%. The proposed reaction kinetic models which related the feed volume and membrane structure parameters predict the esterification process well at different conditions.
