摘要：
Antibiotics in pharmaceutical and aquaculture wastewater is a growing threat to the environment of world, due to the induction of drug-resistant bacteria and the harm to the aquatic organisms. Photocatalytic membrane, which has immobilized photocatalyst on membrane is an effective and environmentally friendly technology for antibiotics degradation. In this study, a novel photocatalytic membrane was prepared by loading ZnO/N-gC(3)N(4) composite on commercial polymer membrane with glutaraldehyde as a crosslinker through pressure driven filtration. The loading of the photocatalyst over the membranes was validated by Fourier transform infrared spectroscopy, scanning electron microscope and X-ray photoelectron spectroscopy. The photocatalytic properties of ZnO/N-g-C3N4 composite membrane were observed efficient for degradation of tetracycline, ciprofloxacin and ofloxacin in both immersion and filtration model under visible light (l > 420 nm). Especially, a ZnO/N-g-C3N4 loading amount of 1.12 g/cm(2) and glutaraldehyde concentration of 45% led to the degradation rate of 100% and 80% for tetracycline at 5 mg/L and 10 mg/L, respectively. Low trans-membrane pressure (0.005 MPa) and narrow membrane size (50 kDa) were favorable for antibiotics degradation in filtration model due to long reaction time on membrane surface. Construction and performance of ZnO/N-g-C3N4 composite membrane might provide new strategy for energy saving wastewater treatment. (C)& nbsp;2022 The Author(s). Published by Elsevier B.V.& nbsp;

摘要：
In this study, the proteins of selenium-enriched walnuts produced in three seleniferous areas of Enshi (Yesanguan (YS), Lichuan (LC), and Sancha (SC)) were extracted by the alkaline method. Response surface methodology (RSM) was used for the optimization of protein extraction. The total selenium (Se) content of walnut proteins was 1.3345 mg/kg in YS, 0.6219 mg/kg in LC, and 0.4219 mg/kg in SC, and about 82-85% was organic Se. The major Se speciation was selenocystine and selenomethionine. All walnut proteins showed antioxidant activities in a Se-concentration-dependent manner. The antioxidant activity of YS walnut was stronger than that of other proteins, which exhibited high DPPH radical (69.5%) and moderate hydroxyl radical (46.5%) scavenging activities at 1.0 mg/ml. After enzymatic hydrolysis, protein hydrolysates displayed significantly higher antioxidant capacities than undigested proteins at all tested concentrations. The overall results indicated that Se-enriched walnuts have great potential as functional food additives for a dietary supplement. Novelty impact statement Organic selenium accounts for more than 82% of the total Se in walnut proteins, in which SeCys(2) and SeMet are major organic forms of selenium. The Se content in walnut proteins is positively correlated with the antioxidant ability. Walnut protein hydrolysates exhibit better antioxidant activities than proteins.

摘要：
Ginkgolide is a unique terpenoid natural compound in Ginkgo biloba, and it has an important medicinal value. Proper selenium has been reported to promote plant growth and development, and improve plant quality, stress resistance, and disease resistance. In order to study the effects of exogenous selenium (Se) on the physiological growth and the content of terpene triolactones (TTLs) in G. biloba seedlings, the seedlings in this work were treated with Na2SeO3. Then, the physiological indexes, the content of the TTLs, and the expression of the related genes were determined. The results showed that a low dose of Na2SeO3 was beneficial to plant photosynthesis as it promoted the growth of ginkgo seedlings and increased the root to shoot ratio. Foliar Se application significantly increased the content of soluble sugar and protein and promoted the content of TTLs in ginkgo leaves; indeed, it reached the maximum value of 7.95 mg/g in the ninth week, whereas the application of Se to the roots inhibited the synthesis of TTLs. Transcriptome analysis showed that foliar Se application promoted the expression levels of GbMECPs, GbMECT, GbHMGR, and GbMVD genes, whereas its application to the roots promoted the expression of GbDXS and GbDXR genes. The combined analysis results of metabolome and transcriptome showed that genes such as GbDXS, GbDXR, GbHMGR, GbMECPs, and GbCYP450 were significantly positively correlated with transcription factors (TFs) GbWRKY and GbAP2/ERF, and they were also positively correlated with the contents of terpene lactones (ginkgolide A, ginkgolide B, ginkgolide M, and bilobalide). Endogenous hormones (MeJA-ILE, ETH, and GA7) were also involved in this process. The results suggested that Na2SeO3 treatment affected the transcription factors related to the regulation of endogenous hormones in G. biloba, and further regulated the expression of genes related to the terpene synthesis structure, thus promoting the synthesis of ginkgo TTLs.
摘要：
This study was conducted to evaluate the effects of different Selenium (Se) sources on growth performance, intestinal function and antioxidant status of weaned piglets. A total of 300 weaned pigs were randomly allocated to 5 treatment groups with 5 replicates of 12 pigs/pen. The control group was corn-soybean basal diet without any additional Se supplement. The experimental diets were supplemented with 0.3 mg/kg of Se from sodium selenite (SS), Se-enriched yeast (SEY), Se-enriched Cardamine violifolia (SEC) and 0.3+0.3 mg/kg of Se from SEY and SEC, respectively. The trial lasted for 4 weeks. The results showed that diets supplementation with SEY, SEC or SEY+SEC could improve average daily gain and reduce feed/gain ratio during the entire study. Compared with the control group, SEC or SEY+SEC improved intestinal morphology, indicated by greater villus height and villus height/ crypt depth ratio. In addition, SEC or SEY+SEC also increased maltase and lactase activities as well as tight junction protein expression. Different Se sources decreased malondialdehyde (MDA) concentration and improved superoxide dismutase (SOD) activity in serum. In the jejunum, SEY or SEC reduced MDA concentration and increased total antioxidant capacity (T-AOC) compared with the control group. Moreover, SEY+SEC increased the antioxidant parameters including SOD and T-AOC in the jejunum. Dietary SEY or SEC supplementation significantly increased the mRNA expression of selenoproteins including thioredoxin reductase 1 (TXNRD1), selenoprotein I (SELENOI), selenoprotein S (SELENOS), and selenoprotein P (SELENOP) in the jejunum. In conclusion, organic Se sources, especially Cardamine violifolia, improve growth performance, potentially by regulating intestinal function, antioxidant capacity and selenoprotein expression in piglets.

摘要：
In this study, headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) and principal component analysis (PCA) were used to analyze the volatile flavor compounds in brown rice flour (BRF) and brown rice noodles (BRNs) prepared by different methods. White rice flour (WRF) and white rice noodles (WRNs) were used for comparison. The results revealed significant differences in volatile flavor compounds between BRFs and BRNs, and the types of volatile flavor compound in BRF were more than WRF. Compared with WRF, aldehydes increased in the BRF produced by refilling. The primary volatile flavor compounds of brown rice flour made by crushing brown rice fully (BRF-F) were 2-acetyl-1-pyrroline, 6-methyl-5-hepten-2-one, 2-heptanone, 2,3-buta-nedione, 2-octanone, 2-butanone, 1-hexanol, 1-pentanol, ethanol, 2-methylbutanol, 3-methylbutanol, and 2-methylpropanol. Ethyl acetate was found in all rice flour and rice noodle samples. The contents of 2-methylpro-panol, 2-hexanone, 2-methylbutanal, 3-methylbutanal, ethanol and acetone increased after processing rice flour into rice noodles, while the contents of 2-acetyl-1-pyrroline, 6-methyl-5-hepten-2-one, 1-hexanol, 2-heptanone, 1-pentanol and 2,3-butanedione decreased. This research demonstrated the promising application of extrusion in fabricating brown rice flour with satisfactory flavor preservation for refilling in WRF.

摘要：
Cardamine violifolia, a species belonging to the Brassicaceae family, is a selenium hyperaccumulator and a nutritious leafy vegetable. Our previous study showed that C. violifolia leaves are rich in total phenolic acids, but the composition and corresponding genes remain unknown. In this study, we investigated the phenolic acid compounds and potential gene regulation network in the outer leaves (OL) and central leaves (CL) of C. violifolia using transcriptome and metabolome analyses. Results showed that the OL contained a higher total phenolic acid content than the CL. Metabolome analysis revealed a total of 115 phenolic acids, 62 of which (e.g., arbutin, rosmarinic acid, hydroxytyrosol acetate, and sinapic acid) were differentially accumulated between the CL and OL of C. violifolia. Transcriptome analysis showed that the differentially expressed genes were significantly enriched in the pathways of secondary metabolite biosynthesis and phenylpropanoid biosynthesis. Conjoint analysis of the transcriptome and metabolome indicated that seven genes (CYP84A1, CYP84A4, CADH9, SGT1, UGT72E1, OMT1, and CCR2) and eight phenolic acids (sinapic acid, sinapyl alcohol, 5-O-caffeoylshikimic acid, sinapoyl malate, coniferin, coniferyl alcohol, L-phenylalanine, and ferulic acid) constituted a possible regulatory network. This study revealed the phenolic acid compounds and possible regulatory network of C. violifolia leaves and deepened our understanding of its nutrient value.

摘要：
Epimedium flavum Stearn, which belongs to Berberidaceae, is mainly distributed in the Sichuan province of China. In this study, the complete chloroplast genome of E. flavum was reported for the first time. The whole genome of E. flavum was 159,134 bp in length, and revealed a typical quadripartite structure, including two copies of an inverted repeat (IR) region of 27,735 bp separating a large single-copy region (LSC, 86,576 bp) and a small single-copy region (SSC, 17, 088 bp). The chloroplast genome contained 112 unique genes, including 78 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenetic analysis showed that E. flavum of series Davidianae was firstly clustered with E. brevicornu of ser. Brachyerae.

摘要：
Streptococcus suis, a ubiquitous bacterial colonizer in pigs, has recently extended host range to humans, leading to a global surge of deadly human infections and three large outbreaks since 1998. To better understand the mechanisms for the emergence of cross-species transmission and virulence in human, we have sequenced 366 S. suis human and pig isolates from 2005 to 2016 and performed a large-scale phylogenomic analysis on 1,634 isolates from 14 countries over 36 years. We show the formation of a novel human-associated clade (HAC) diversified from swine S. suis isolates. Phylogeographic analysis identified Europe as the origin of HAC, coinciding with the exportation of European swine breeds between 1960s and 1970s. HAC is composed of three sub-lineages and contains several healthy-pig isolates that display high virulence in experimental infections, suggesting healthy-pig carriers as a potential source for human infection. New HAC-specific genes are identified as promising markers for pathogen detection and surveillance. Our discovery of a human-associated S. suis clade provides insights into the evolution of this emerging human pathogen and extend our understanding of S. suis epidemics worldwide.
The increasing incidences of human infections caused by Streptococcus suis indicate that this bacterium may undergo adaptive evolution in humans. In this study, a novel clade of S. suis strongly associated with human infections was identified.
