Abstract
Long-term manure application gives rise to the uptake of antibiotics by plants and antibiotics subsequent entry into the food chain, representing an important alternative pathway for human exposure to antibiotics. The antibiotics can cause negative effects on crop growth and productivity. The bioaccumulation and translocation of 14 target antibiotics in peanuts (Arachis hypogaea L.) and their effects on peanut relative biomass in fields with long-term (≥15 years) manure application were studied. The results showed that all the target antibiotics were found in manures and rhizosphere soils, and most of them were found in all peanut tissues (roots, shells, kernels, stem, and leaves). The antibiotic concentrations in peanut tissues were varied with the characteristics of antibiotics in soils. Tetracyclines were the dominating antibiotic compounds in all peanut tissues, accounting for 61%-80% of total antibiotics due to their relatively high concentration in rhizosphere soil. Most tetracyclines and quinolones preferentially accumulated in the roots and translocated to other peanut tissues than sulfonamides and macrolides. Furthermore, the influence of antibiotics in soil and crops on relative biomass of crop tissues varied with tissues and antibiotic types. Antibiotics significantly inhibited the tissue relative biomass in most cases, although stimulation of some antibiotics to crop biomass was also observed. We found that 18.3% of the variance of the peanut relative biomass was explained by antibiotics in soils and tissues. The estimated threshold of daily intake values suggests that the consumption of peanut kernels grown in field conditions with long-term manure application presents a moderate risk to human health.

Abstract
Plants and bacteria individually as well as in synergism with each other hold a great potential to degrade a wide range of environmental pollutants. Floating treatment wetlands (FTWs) is an efficient and low-cost technology that uses the synergistic interaction between plant roots and microbes for in situ remediation of wastewater. The present study aims to assess the feasibility of FTW-based remediation of oil field-produced wastewater using an interaction between two plant species, Typha domingensis and Leptochloa fusca, in partnership with a consortium of crude oil-degrading bacterial species, Bacillus subtilis LORI66, Klebsiella sp. LCRI87, Acinetobacter Junii TYRH47, and Acinetobacter sp. BRSI56. All the treatments reduced contaminant levels, but T. domingensis, in combination with bacterial inoculation, exhibited the highest reduction in hydrocarbon (95%), COD (90%), and BOD content (93%) as compared to L. fusca. This combination maximally promoted increases in fresh biomass (31%), dry biomass (52%), and length (25%) of plants as well. This effect was further signified by the persistence of bacteria (40%) and considerable abundance (27%) and expression (28.5%) of the alkB gene in the rhizoplane of T. domingensis in comparison to that of L. fusca. The study, therefore, suggests that T. domingensis, in combination with bacterial consortium, has significant potential for treatment of oil field-produced water and can be exploited on large scale in FTWs.

Abstract
Early stages of ontogenesis determining subsequent growth, development, and productivity of crops can be affected by wastewater and sludge contaminated with pharmaceuticals. Diclofenac (DCF) and paracetamol (PCT; both 0.0001 to 10 mg/L) did not affect seed germination and primary root length of onion, lettuce, pea, and tomato. Conversely, 20-day-old pea and maize plants exhibited decrease in biomass production, leaf area (by approx. 40% in pea and 70% in maize under 10 mg/L DCF), or content of photosynthetic pigments (by 10% and 60% under 10 mg/L PCT). Quantum yields of photosystem II were reduced only in maize (FV/FM and ΦII by more than 40% under 10 mg/L of both pharmaceuticals). Contents of H2O2 and superoxide increased in roots of both species (more than four times under 10 mg/L PCT in pea). Activities of antioxidant enzymes were elevated in pea under DCF treatments, but decreased in maize under both pharmaceuticals. Oxidative injury of root cells expressed as lowered oxidoreductase activity (MTT assay, by 40% in pea and 80% in maize) and increase in malondialdehyde content (by 60% and 100%) together with the membrane integrity disruption (higher Evans Blue accumulation, by 100% in pea and 300% in maize) confirmed higher sensitivity of maize as a C4 monocot plant to both pharmaceuticals.

Abstract
Adverse effects of sulfonamide antibiotics (SAs) include growth inhibition and antioxidant activation which showed trade-off effects. Yet, the influence of food availability on such effects have not been thoroughly investigated. Caenorhabditis elegans were exposed to four SAs at high and low food availabilities which were represented by the optical densities of bacteria at 600 nm. The nematode feeding, growth and antioxidants including superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) were determined. Results showed that the control nematodes at low food availability had less growth and greater antioxidant responses than the nematodes at high food availability. In SA exposure, the nematode growth in the presence of food (at both high and low food availability) was less than that in its absence, supporting the role of food as an exposure pathway. The nematode growth at low food availability showed significantly greater inhibition than at high food availability (p < 0.05). The nematode antioxidants showed stimulations, and CAT had the greatest stimulation. Moreover, the stimulation on CAT at low food availability were significantly higher than those at high food availability (p < 0.05). That is to say, SA exposure at low food availability further biased the trade-off effects towards more energy investment in antioxidant with less in growth. Further studies on the expression levels of CAT encoding genes demonstrated that cells in intestines were the main antioxidant response sites, which further supported the contributions of food to the observed toxicities.

Abstract
Phenol is a commonly found organic pollutant in industrial wastewaters. Its ecotoxicological significance is well known and, therefore, the compound is often required to be removed prior to discharge. In this study, plant-bacterial synergism was established in floating treatment wetlands (FTWs) in an attempt to maximize the removal of phenol from contaminated water. A common wetland plant, Typha domingensis, was vegetated on a floating mat and augmented with three phenol-degrading bacterial strains, Acinetobacter lwofii ACRH76, Bacillus cereus LORH97, and Pseudomonas sp. LCRH90, to develop FTWs for the remediation of water contaminated with phenol. All of the strains are known to have phenol-reducing properties, and grow well in FTWs. Results showed that T. domingensis was able to remove a small amount of phenol from the contaminated water; however, bacterial augmentation enhanced the removal potential significantly, i.e., 0.146 g/m2/day vs. 0.166 g/m2/day, respectively. Plant biomass also increased in the presence of bacterial consortia; and inoculated bacteria displayed successful colonization/survival in the rhizosphere, root interior and shoot interior of the plant. Similarly, highest reduction in chemical oxygen demand (COD), biochemical oxygen demand (BOD5), and total organic carbon (TOC) was achieved by the combined application of plants and bacteria. The study demonstrates that the plant-bacterial synergism in a FTW may be a more effective approach for the remediation of phenol-contaminated water.

Abstract
Polybrominated diphenyl ethers (PBDEs) are toxic chemicals widely distributed in the environment, but few studies are available on their potential toxicity to rice at metabolic level. Therefore we exposed ten rice (Oryza sativa) varieties to 2,2',4,4'-tetrabromodiphenyl ether (BDE-47), a predominant congener of PBDEs, in hydroponic solutions with different concentrations. Two varieties that showed different biological effects to BDE-47, YY-9 and LJ-7, were screened as sensitive and tolerant varieties according to changes of morphological and physiological indicators. Metabolic research was then conducted using gas chromatography-mass spectrometry combined with diverse analyses. Results showed that LJ-7 was more active in metabolite profiles and adopted more effective antioxidant defense machinery to protect itself against oxidative damages induced by BDE-47 than YY-9. For LJ-7, the contents of 13 amino acids and 24 organic acids, especially l-glutamic acid, beta-alanine, glycolic acid and glyceric acid were up-regulated significantly which contributed to scavenging reactive oxygen species. In the treatment of 500 μg/L BDE-47, the contents of these four metabolites increased by 33.6-, 19.3-, 10.6- and 10.2-fold, respectively. The levels of most saccharides (such as d-glucose, lactulose, maltose, sucrose and d-cellobiose) also increased by 1.7-12.4 fold which promoted saccharide-related biosynthesis metabolism. Elevation of tricarboxylic acid cycle and glyoxylate and dicarboxylate metabolism enhanced energy-producing processes. Besides, the contents of secondary metabolites, chiefly polyols and glycosides increased significantly to act on defending oxidative stress induced by BDE-47. In contrast, the levels of most metabolites decreased significantly for YY-9, especially those of 13 amino acids (by 0.9%-67.1%) and 19 organic acids (by 7.8%-70.0%). The positive metabolic responses implied LJ-7 was tolerant to BDE-47, while the down-regulation of most metabolites indicated the susceptible nature of YY-9. Since metabolic change might affect the yield and quality of rice, this study can provide useful reference for rice cultivation in PBDEs-polluted areas.

Abstract
The presence of antibiotic residues in vegetables has been highlighted as a risk to human health; antibiotics not only cause toxic effects to plants but can also induce antibiotic resistance gene (ARG) expression. Using a soil-free approach, this study aimed to explore the response of ginger growth to tetracycline (TC) pollution and to assess the levels of antibiotic residues in different plant organs and the presence of ARGs in the rhizome. Ginger growth in a highly TC-contaminated environment was remarkably inhibited. Photosynthetic parameters, fluorescence parameters, and some physiological indicators (oxidative substances, photosynthetic pigments, enzyme activity, etc.) were negatively influenced by TC contamination. Although the superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activity levels significantly increased, their effects appear to be limited. The accumulation of TC in the rhizome (28.1 mg kg-1) was greater than that in the roots, stem, or leaves. All tested antibiotic resistance genes except for tetL were detectable in the rhizome, and their relative abundance was in the order integron1>tetG > tetA > tetC > tetB > tetM. The level of TC in ginger rhizomes was much higher than the maximum residue limits. The potential dose of TC acquired from the consumption of ginger grown in a highly TC-contaminated environment poses no obvious risk to adults but may be a threat to children.

Abstract
Helophytic plants contribute significantly in phytoremediation of a variety of pollutants due to their physiological or biochemical mechanisms. Phenol, which is reported to have negative/deleterious effects on plant metabolism at concentrations higher than 500 mg/L, remains hard to be removed from the environmental compartments using conventional phytoremediation procedures. The present study aims to investigate the feasibility of using P. australis (a helophytic grass) in combination with three bacterial strains namely Acinetobacter lwofii ACRH76, Bacillus cereus LORH97, and Pseudomonas sp. LCRH90, in a floating treatment wetland (FTW) for the removal of phenol from contaminated water. The strains were screened based on their phenol degrading and plant growth promoting activities. We found that inoculated bacteria were able to colonize in the roots and shoots of P. australis, suggesting their potential role in the successful removal of phenol from the contaminated water. Pseudomonas sp. LCRH90 dominated the bacterial community structure followed by A. lowfii ACRH76 and B. cereus LORH97. The removal rate was significantly high when compared with the individual partners, i.e., plants and bacteria separately. The plant biomass, which was drastically reduced in the presence of phenol, recovered significantly with the inoculation of bacterial consortia. Likewise, highest reduction in chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total organic carbon (TOC) is achieved when both plants and bacteria were employed. The study, therefore, suggests that P. australis in combination with efficient bacteria can be a suitable choice to FTWs for phenol-degradation in water.

Abstract
The use of fluoroquinolones (FQs) antibiotics as therapeutic agents and growth promoters is increasing worldwide; however their extensive uses are also resulting in antibiotic resistance among world communities. FQs have also become one of the major contaminants in the waste water bodies, which are not even completely removed during the treatment processes. Furthermore, their abundance in agricultural resources, such as the irrigation water, the bio-solids and the livestock manure can also affect the soil micro-environment. These antibiotics in soil tend to interact in several different ways to affect soil flora and fauna. The current review endeavors to highlight the some critical aspects of FQs prevalence in the environment. The review presents a detailed discussion on the pathways and abundance of FQs in soil. The discussion further spans the issue of sorption and FQs transformation into the soil better understand of their behavior and their toxicity to soil flora and fauna.

Abstract
MicroRNAs (miRNAs) play key roles in plant growth, development and responses to abiotic stress. Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants. However, it is yet unknown how miRNAs work during PAH uptake by plant roots. Thus, in this study we ascertain phenanthrene (a model PAH)-responsive miRNAs using small RNA high-throughput deep sequencing and their target genes in wheat roots. We identified 108 conserved and non-conserved miRNA members belonging to 82 miRNA families and found 11 differentially expressed miRNAs, among which four miRNAs (miR156, miR164, miR171a and miR9678-3p) were up-regulated and the other seven miRNAs (miR398, miR531, miR1121, miR5048-5p, miR9653b, miR9773 and miR9778) were down-regulated. ABC-transporter-related Gene CA704421 and CA697226 did not respond to phenanthrene exposure. miR156 and miR164 might regulate directly the growth and development of wheat roots by targeting SPL and NAC, respectively. miR398 and miR1121 could regulate oxidative reactions to respond to phenanthrene stress. Additionally, miR9773 might involve phenanthrene metabolism through acting on CYP450. Therefore, it is concluded that phenanthrene triggers variation in miRNA expression, which is associated with uptake of and response to phenanthrene. These findings are of significance for further understanding miRNA regulation mechanisms on PAH uptake, and providing guidance for screening of resistant cultivars in crop production and phytoremediation of PAH-contaminated soils or water at genetic level.

Hepatobiliary Pancreat Dis Int 2017; 16:519-527. [PMID: 28992885 DOI: 10.1016/s1499-3872(17)60038-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2016] [Accepted: 06/23/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND Biliary cancers are more common in females, and previous studies have suggested that Helicobacter pylori (H. pylori) exists in the biliary system. However, the effects of H. pylori infection and estrogen on the biological behaviors of human biliary epithelium mucosa remain unknown. The present study aimed to clarify their effects on the proliferation, apoptosis, migration and oxidative DNA damage of a human intrahepatic biliary epithelial cell (HIBEC) line in vitro. METHODS HIBECs were co-cultured with 17β-estradiol (at 10-9 mol/L, 10-7 mol/L, and 10-5 mol/L) and H. pylori (at MOI=0.5:1, 1:1, and 2:1) and continuously passaged until the 15th generation (approximately 45 days). Then, the following assays were performed. HIBEC proliferation was measured using the CCK-8 assay, plate clone-formation assay and by determining Ki-67 expression with immunocytochemistry; cell apoptosis and migration were investigated using Annexin-V/PI and transwell assays, respectively; and reactive oxygen species (ROS) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) production were detected by flow cytometry and immunofluorescence staining combined with confocal laser scanning microscopy, respectively. The results were the basis for evaluating the level of oxidative stress and the related DNA damage in HIBECs. RESULTS HIBECs maintained a normal morphology and vitality when treated with 17β-estradiol (at 10-9 mol/L) and H. pylori (at MOI=0.5:1 and 1:1). 17β-estradiol at 10-7 mol/L and 10-5 mol/L and H. pylori at MOI=2:1, by contrast, caused cell death. Compared with controls, HIBECs treated with 17β-estradiol (10-9 mol/L) and H. pylori (MOI=1:1) had a higher up-regulation of proliferation, Ki-67 expression, clone formation, migration activity and the expression of ROS and 8-OHdG and exhibited a down-regulation of apoptosis. The above effects were further increased when 17β-estradiol and H. pylori were combined (P<0.05). CONCLUSIONS H. pylori and 17β-estradiol, separately or in combination, promoted cell proliferation and suppressed apoptosis of HIBECs in vitro. The above phenomena might be related to oxidative stress and its subsequent DNA damage with H. pylori and 17β-estradiol.
