nimization of systemic side effects. The major therapeutic strategy for acid-related gastrointestinal diseases in clinic is to reduce the excretion of gastric acid by oral administration of proton-pump inhibitors (PPIs). However, it is quite a challenge to study the oral absorption behaviors of PPIs considering their extreme instability under gastrointestinal environment. As a result, little information has been reported on PPI oral absorption so far, hindering the further development of PPI-contained oral preparations. Here, we first investigated the degradation rate of three representative PPIs, including ilaprazole, ilaprazole sodium and rabeprazole sodium. Then a modified in situ intestine absorption method in rat was established through the temperature control by the heat exchangers, the perfusate was kept at physiological temperature only when passing through the intestine while it was maintained at 4 °C outside the intestine. Therefore PPIs could maintained sufficiently high stability under proper temperature control. Our data demonstratester metabolism in male rats after oral absorption. Our study provided a valuable guidance for the design of oral formulation and the optimization of PPI-contained formulations. By functionalizing the surface of PEG-liposomes with linkers bearing quaternary ammonium compounds (QACs), we generated novel bacteria disruptors with anti-adhesive properties and reduced cytotoxicity compared to free QACs. Furthermore, QAC-functionalized liposomes are a promising platform for future drug encapsulation. The QAC (11-mercaptoundecyl)-N,N,N-trimethylammonium bromide (MTAB) was attached to maleimide-functionalized liposomes (DSPE-PEG) via thiol linker. The MTAB-functionalized liposomes were physicochemically characterized and their biological activity, in terms of anti-adherence activity and biofilm prevention in Escherichia coli were assessed. The results showed that MTAB-functionalized liposomes inhibit bacterial adherence and biofilm formation while reducing MTAB toxicity. The aims of this work were to assess the PAH exposure among roofers and to identify relevant biomarkers for monitoring occupational exposure. Several campaigns were conducted between 2004 and 2017, with 28 individual air samples and 240 urinary samples collected from 73 roofers. Seventeen parent PAHs and 14 urinary biomarkers, metabolites of pyrene (1-OHP), benzo(a)pyrene (3-OHBaP and TetraolBaP), naphthalene (1- and 2-naphtols), fluorene (1- 2- 3- 9-fluorenols) and phenanthrene (1- 2- 3- 4- 9-phenanthrols), were analysed. Three exposure groups were considered soft-applied roofing using polymer-modified bitumen ("PMB"), hot-applied roofing using oxidized bitumen ("OB") and the tearing off of old roof coatings containing coal tar ("CT"). The PAHs containing 2-3 rings were much more abundant, and the highest airborne levels were observed in the "CT" group. The biomonitoring results were consistent with these results, with a large predominance of 2-3 ring PAH metabolites. 1-OHP, 3-fluorenol and 2-phenanthrol were better correlated with airborne levels and less influenced by smoking than the other metabolites. Conversely, 1-/2-naphtol levels were heavily influenced by smoking and not correlated with airborne naphthalene levels. Moreover, 3-OHBaP and TetraolBaP levels were very low when applying bitumen membranes, and much higher exposures were observed during tear-off activities. In this context, the recommended strategy for roofer biomonitoring should include 1-OHP, fluorenols and phenanthrols, as well as carcinogenic BaP metabolites (3-OHBaP or TetraolBaP) when evaluating the occupational exposure of roofers that are tearing off old roof coatings. V.OBJECTIVE To identify the association between UGT1A1 Gly71Arg and TATA promoter polymorphisms and neonatal hyperbilirubinemia. METHODS The studies related to the correlation between UGT1A1 Gly71Arg and TATA promoter polymorphisms and neonatal hyperbilirubinemia were searched systematically in various databases. see more According to the presence or absence of significant heterogeneity, a random-effect or fixed-effect model was chosen to estimate the overall odds rations (ORs) and 95% confidence intervals (CIs). RESULTS Totally 21 studies on Gly71Arg polymorphism including 4738 neonates and 13 studies on TATA promoter polymorphism involving 2841 neonates were identified. Significant associations were presented between Gly71Arg polymorphism and neonatal hyperbilirubinemia in Asia [A vs. G, OR(95%CI) 2.327(1.904-2.845), P less then 0.001; AA + GA vs. GG, OR(95%CI) 2.253(1.954-2.598), P less then 0.001; AA vs. GG + GA, OR(95%CI) 5.166(3.520-7.564), P less then 0.001; AA vs. GG, OR(95%CI) 6.458(4.376-9.531), P less then 0.001; GA vs. GG, OR(95%CI) 1.920(1.654-2.228), P less then 0.001] and Africa [A vs. G, OR(95% CI) 9.750(1.214-78.301), P = 0.032; AA + GA vs. GG, OR(95% CI) 11.000(1.290-93.832), P = 0.028; GA vs. GG, OR(95% CI) 10.000(1.163-85.998), P = 0.036]. TATA promoter polymorphism was associated with an increased risk of neonatal hyperbilirubinemia in Asia [TA7/7 vs. TA6/6 + TA6/7, OR(95%CI) 1.670(1.034-2.696), P = 0.036] and Europe [TA7/7 vs. TA6/6 + TA6/7, OR(95%CI) 2.627(1.722-4.008), P less then 0.001]. CONCLUSION The risk of neonatal hyperbilirubinemia may be increased by the variation of UGT1A1 Gly71Arg in Asia and Africa, as well as the variation of UGT1A1 TATA promoter in Asia and Europe. The emergence of somaclonal variability in in vitro cultures is undesirable during micropropagation, but this phenomenon may be a source of genetic variability sought by breeders. The main factors that affect the appearance of variability are known, but the exact mechanism has not yet been determined. In this paper, we used next-generation sequencing and comparative genomics to study changes in the genomes of cucumber lines resulting from in vitro regeneration and somaclonal mutation in comparison to a reference, the highly inbred B10 line. The total number of obtained polymorphisms differed between the three somaclonal lines S1, S2 and S3, with 8369, 7591 and 44510, respectively. Polymorphisms occurred most frequently in non-coding regions and were mainly SNPs. High-impact changes accounted for 1%-3% of all polymorphisms and most often caused an open reading frame shift. Functional analysis of genes affected by high impact variants showed that they were related to transport, biosynthetic processes, nucleotide-containing compounds and cellular protein modification processes.
