Investigation on sampling artifacts of particle associated PAHs using ozone denuder systems

Kai LIU, Fengkui DUAN, Kebin HE, Yongliang MA, Yuan CHENG

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 2,   Pages 284-292 doi: 10.1007/s11783-013-0555-7

Abstract: PAHs (mainly in particle phase) are susceptible to atmospheric oxidant gases, especially ozone, nitrogenThe goal of this work was to investigate particle associated PAHs sampling artifacts caused by ozoneIn general, nine particle-bound PAHs observed from conventional sampler were all lower than those fromThe total PAHs (particle phase) concentration was averagely underestimated by 35.9% in conventional samplingHigh temperature can increase loss of particle associated PAHs during sampling.

Multiphase redistribution differences of polycyclic aromatic hydrocarbons (PAHs) between two successive

Rufeng LI,Chenghong FENG,Dongxin WANG,Baohua LI,Zhenyao SHEN

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 2,   Pages 381-389 doi: 10.1007/s11783-015-0817-7

Abstract: This study took polycyclic aromatic hydrocarbons (PAHs) as typical organic contaminants and investigatedthe release behaviors between two successive suspensions with a particle entrainment simulator (PES)overlying water via facilitating the re-adsorption of dissolved PAHs onto the suspended particles.Fast-release and slow-release periods of PAHs were successively observed in the both suspensions.More vigorous desorption and re-absorption of PAHs were induced in the second suspension.

Fanconi anemia gene-associated germline predisposition in aplastic anemia and hematologic malignancies

Frontiers of Medicine 2022, Volume 16, Issue 3,   Pages 459-466 doi: 10.1007/s11684-021-0841-x

Abstract: Whether Fanconi anemia (FA) heterozygotes are predisposed to bone marrow failure and hematologic neoplasm is a crucial but unsettled issue in cancer prevention and family consulting. We retrospectively analyzed rare possibly significant variations (PSVs) in the five most obligated FA genes, BRCA2, FANCA, FANCC, FANCD2, and FANCG, in 788 patients with aplastic anemia (AA) and hematologic malignancy. Sixty-eight variants were identified in 66 patients (8.38%). FANCA was the most frequently mutated gene (n = 29), followed by BRCA2 (n = 20). Compared with that of the ExAC East Asian dataset, the overall frequency of rare PSVs was higher in our cohort (P = 0.016). BRCA2 PSVs showed higher frequency in acute lymphocytic leukemia (P = 0.038), and FANCA PSVs were significantly enriched in AA and AML subgroups (P = 0.020; P = 0.008). FA-PSV-positive MDS/AML patients had a higher tumor mutation burden, higher rate of cytogenetic abnormalities, less epigenetic regulation, and fewer spliceosome gene mutations than those of FA-PSV-negative MDS/AML patients (P = 0.024, P = 0.029, P = 0.024, and P = 0.013). The overall PSV enrichment in our cohort suggests that heterozygous mutations of FA genes contribute to hematopoietic failure and leukemogenesis.
