Sequencing artifacts, clonal hematopoietic potential mutation indeterminate (CHIP) and the heterogeneity of the tumor has been hypothesized to contribute to the low suitability of tissue and cell-free DNA (cfDNA) with a targeted molecular profiling sequencing.We cfDNA analyzed by targeted sequencing of Hypersaline wastewater may pose a threat to the biological wastewater treatment process. samples from 30 and 77 EGFR-mutant wild-type EGFR lung cancer metastatic non-small cell (mNSCLC) patients. discordant cases solved with digital droplet PCR (ddPCR) .
With cfDNA testing from a healthy donor, we developed an algorithm to recognize the sequencing artifacts. Applying this method to cfDNA of patients mNSCLC, EGFR mutations detected with good sensitivity (76.7%) and specificity (97.4%). In contrast, the sensitivity and specificity for the KRAS variant was 61.5% and 93.8%, respectively. All of EGFR and KRAS variant was detected in the plasma but not in the network is confirmed by ddPCR, thus excluding sequencing artifacts. In a small proportion of cases, KRAS mutations are found in plasma samples was confirmed in tumor tissue showed tumor heterogeneity.
KRAS variant was found to be possible sub-clonal compared with the EGFR mutation, and the correlation between the clonal origin and frequency of detection in plasma was found. In the case of both EGFR and KRAS variant in cfDNA, we can show the presence of KRAS in the tumor tissue variants associated with lack of response to tyrosine kinase inhibitors (TKI) .Although sequencing artifacts can be identified in order cfDNA targets, tumor heterogeneity and CHIP are likely to affect the suitability between plasma and tissue testing.
Hypersaline wastewater may pose a threat to the biological wastewater treatment process. Reactor-based aerobic granular sludge sequencing batch (SBR) perform simultaneous nitrification, denitrification and removal of phosphorus (SNDPR) was evaluated with an increase in salinity of 1 to 2% (w / v). nitrogen deletion performance is not affected by the salinity of up to 20 g / L in terms of nitrification and denitrification are reliable and efficient.

Enhanced biological elimination of phosphorus (EBPR) process actually worsened in the salinity of up to 2%, in contrast with the removal of phosphorus excellent at 1%. Profile phosphorus over one cycle shows that the higher salinity not only inhibits anaerobic phosphorus release, but also hampered the aerobic / anoxic phosphorus uptake.
