Two CPB-like genes, one CPO-like gene, and five CPA-like genes were found based on similarity to mouse and human sequences (Fig. 1).
For the purpose of this analysis, the study was subdivided into two time intervals: CPB and non-CPB, where CPB was defined as the period between initiation and termination of CPB and non-CPB was defined as both the periods from the start of the remifentanil infusion until CPB was initiated and the periods between termination of CPB and completion of blood sampling.
In addition, four other CPB columns are cured at 7, 28, 90 and 150 days, and then extensive laboratory testing is carried out on the CPB samples with regards to their thermal conductivity, saturated hydraulic conductivity, water retention properties, and mechanical and physical properties.
Seven no-CPB patients (12.7%) developed AKI and their median uNGAL POST was 330 (42.6 to 489.9) μg/l compared with 13.6 (6.9 to 38.3) μg/l in the 48 patients without AKI (P 0.0001).
Eighteen infants and children (eight female) undergoing CPB were prospectively studied.
The number of specific transcripts was calculated for the standard curve and normalized to two houskeeping genes CPB (Cyclophilin B) und HPRT (Hypoxanthin Phosphoribosyltransferase).
We found a good correlation between postoperative plasma hepcidin and urine hepcidin in patients not developing AKI (six hours after CPB: r = 0.62, P < 0.001), but no correlation in those with subsequent AKI (six hours after CPB: r = 0.18, P = 0.64).
ACT was checked seven times during CPB, but only twice was it longer than 400 s.
Ten minutes after CPB, the TFPI levels were still significantly elevated in comparison with preoperative values but decreased from the end of CPB on to reach baseline values.
No difference was observed between pre-operative or two hours post-CPB urine IL-6 values in patients with AKI versus no AKI (P = 0.65).
Six hours after CPB, concentrations of TNF-α were lower in animals operated on under moderate hypothermia than in the others (P < 0.05; Figure 1a,b).
