High-performance electromagnetic interference shielding (EMI) materials are desirable in aerospace, military and mobile electronics applications. However, fabrication of smart and ultra-lightweight EMI shielding materials with adjustable EMI shielding performance through an energy-efficient and environmental-friendly process is still challenging. Herein, we demonstrate using a conductive biomass-derived D-glucaric acid-chitosan/single-walled carbon nanotube (SWNT/GA-chitosan) polymer composite layer and a crystallized paraffin layer to fabricate ultra-lightweight polyurethane foams with shape memory and adjustable EMI shielding functions, of which the shape change via external stimulus enables the foams to adjust EMI shielding efficiency autonomously. The foam coated with synthesized conductive composite layers shows an exceptional EMI shielding effectiveness of 56 dB at an ultra-low d. of 0.03 g/cm3 with only 0.171 vol% SWNT. The foam also exhibits ultra-high durability over 2000 compression-recovery cycles. Furthermore, introduction of paraffin layer as a reversible network results in shape memory foams with high fixity ratio >95% and recovery ratio >90%. These foams exhibit a wide range of adjustable EMI shielding efficiency from 18 dB to 30 dB by controlling their macroscopic shape from compression. Such smart foams with shape memory and adjustable EMI shielding functions fabricated by an environmental-friendly strategy represent a promising material candidate for the wide applications of EMI shielding.

Otterbach, Sophie L.; Khoury, Holly; Rupasinghe, Thusitha; Mendis, Himasha; Kwan, Kim H.; Lui, Veronica; Natera, Siria H. A.; Klaiber, Iris; Allen, Nathaniel M.; Jarvis, David E.; Tester, Mark; Roessner, Ute; Schmockel, Sandra M. published the artcile< Characterization of epidermal bladder cells in Chenopodium quinoa>, Recommanded Product: D-Glucosaccharic acid, the main research area is characterization epidermal bladder cell Chenopodium quinoa; Chenopodium quinoa; EBC; abiotic stress; epidermal bladder cells; lipidomics; metabolomics.

Chenopodium quinoa (quinoa) is considered a superfood with its favorable nutrient composition and being gluten free. Quinoa has high tolerance to abiotic stresses, such as salinity, water deficit (drought) and cold. The tolerance mechanisms are yet to be elucidated. Quinoa has epidermal bladder cells (EBCs) that densely cover the shoot surface, particularly the younger parts of the plant. Here, we report on the EBC’s primary and secondary metabolomes, as well as the lipidome in control conditions and in response to abiotic stresses. EBCs were isolated from plants after cold, heat, high-light, water deficit and salt treatments. We used untargeted gas chromatog.-mass spectrometry (GC-MS) to analyze metabolites and untargeted and targeted liquid chromatog.-MS (LC-MS) for lipids and secondary metabolite analyses. We identified 64 primary metabolites, including sugars, organic acids and amino acids, 19 secondary metabolites, including phenolic compounds, betanin and saponins and 240 lipids categorized in five groups including glycerolipids and phospholipids. We found only few changes in the metabolic composition of EBCs in response to abiotic stresses; these were metabolites related with heat, cold and high-light treatments but not salt stress. Na+ concentrations were low in EBCs with all treatments and approx. two orders of magnitude lower than K+ concentrations

Tanaka, Eiji; Koitabashi, Motoo; Kitamoto, Hiroko published the artcile< A teleomorph of the ustilaginalean yeast Moesziomyces antarcticus on barnyardgrass in Japan provides bioresources that degrade biodegradable plastics>, Safety of D-Glucosaccharic acid, the main research area is Moesziomyces teleomorph biodegradable plastic; Basidiomycetous yeast; Holomorph; Pseudozyma antarctica; Smut fungi; Teleomorph–anamorph connection; Ustilaginaceae.

The basidiomycetous yeast Moesziomyces antarcticus (often cited as Pseudozyma antarctica), originally isolated from a sediment sample obtained from Lake Vanda in Antarctica, was asexually typified but closely related to the smut fungus Moesziomyces bullatus (Ustilaginales). We found a smut fungus on an ovary of barnyardgrass (Echinochloa crus-galli) in Japan, which had been identified as M. bullatus. The teliospores germinated and formed yeast-like colonies. Physiol. and phylogenetic studies revealed that the characteristics of the yeast-like isolates coincided with those of “”P. antarctica.”” We thus recognized the smut fungus as the teleomorph of M. antarcticus, and then emended the description of M. antarcticus based on the holomorph. The identified fungus could degrade certain biodegradable plastics and produce mannosylerythritol lipids (MELs) in similar qualities as the “”P. antarctica”” type strain. This discovery provides a significant bioresource, as genetically diverse M. antarcticus isolates could be obtained from the smut fungus.

Evolution of virulence traits from adaptation to environmental niches other than the host is probably a common feature of marine microbial pathogens, whose knowledge might be crucial to understand their emergence and pathogenetic potential. Here, we report genome sequence anal. of a novel marine bacterial species, Vibrio bathopelagicus sp. nov., isolated from warm bathypelagic waters (3309 m depth) of the Mediterranean Sea. Interestingly, V. bathopelagicus sp. nov. is closely related to coastal Vibrio strains pathogenic to marine bivalves. V. bathopelagicus sp. nov. genome encodes genes involved in environmental adaptation to the deep-sea but also in virulence, such as the R5.7 element, MARTX toxin cluster, Type VI secretion system and zinc-metalloprotease, previously associated with Vibrio infections in farmed oysters. The results of functional in vitro assays on immunocytes (haemocytes) of the Mediterranean mussel Mytilus galloprovincialis and the Pacific oyster Crassostrea gigas, and of the early larval development assay in Mytilus support strong toxicity of V. bathopelagicus sp. nov. towards bivalves. V. bathopelagicus sp. nov., isolated from a remote Mediterranean bathypelagic site, is an example of a planktonic marine bacterium with genotypic and phenotypic traits associated with animal pathogenicity, which might have played an evolutionary role in the origin of coastal marine pathogens.

Inhibited colitis-associated colon tumorigenesis in mice by modulating fecal microbiota and metabolites>, Category: alcohols-buliding-blocks, the main research area is Lachnum polysaccharide mice colitis colon tumorigenesis fecal microbiota metabolite; AOM/DSS; Colorectal cancer; Gut microbiota; Lachnum sp. polysaccharides.

It is still uncertain whether the consumption of Lachnum sp. polysaccharides (LEP) alleviates colorectal cancer (CRC) through the gut microbiota. In this study, our efforts are focused on the influence of LEP on CRC, intestinal barrier and inflammation, and fecal microbiota and the metabolites, in azoxymethane (AOM)/dextran sodium sulfate (DSS)-induced CRC mice. Results showed that LEP inhibited CRC mouse colon shortening and weight loss, decreased tumor incidence, restored intestinal barrier integrity, and reduced excessive inflammation. LEP consumption significantly altered microbiota overall structure and community, with reduced pernicious bacteria (such as Parabacteroides, Escherichia_Shigella, Desulfovibrio and Helicobacter), and increased beneficial bacterium (such as Alistipes, Alloprevotella and Ruminiclostridium). Fecal-metabolome profile indicated that a total of 43 metabolites were clearly changed, with 10 down-regulated and 33 up-regulated metabolites. In addition, short-chain fatty acids (SCFAs), including acetic acid, propionic acid and n-butyric acid, were significantly increased after LEP administration. Moreover, a strong correlation between the fluctuant gut microbiota and metabolites was found. These findings provided not only deeper insights into the responsibility of LEP for CRC alleviation, and but also the potential of LEP as a promising candidate for CRC prevention and treatment.

In the present study, germinated brown rice (GBR) from three Japonica and three Indica rice cultivars were subjected to metabolomics anal. and volatile profiling. The statistical assessment and pathway anal. of the metabolomics data demonstrated that in spite of significant metabolic changes in response to the germination treatment, the Japonica rice cultivars consistently expressed higher levels of several health-promoting compounds, such as essential amino acids and γ-aminobutyric acid (GABA), than the Indica cultivars. No clear discriminations of the volatile profiles were observed in light of the subspecies, and the concentrations of the volatile organic compounds (VOCs), including alkenes, aldehydes, furans, ketones, and alcs., all exhibited significant reductions ranging from 26.8% to 64.1% after the germination. The results suggest that the Japonica cultivars might be desirable as the raw materials for generating and selecting GBR food products for health-conscious consumers.

In this study, response surface methodol. (RSM) and two artificial neural networks (ANN), multi-layer perceptron (MLP) and radial basis function (RBF), were used for the first time to model and optimize the extraction conditions of phenolic compounds in kidney beans in order to compare and establish effective prediction models. A total of 40 experiments were performed to screen for variables. The highest amount of polyphenols (917.2 mg GAE/100 g DW) and the strongest antioxidant activity (56.03 μmol Trolox/g DW) were obtained under optimal extraction conditions (70 min extraction time, 53% acetone, and 37 mL/g solvent-to-solid ratio). Response values were close to the predicted values with prediction accuracy as RBF > MLP > RSM, indicating that ANN model has higher prediction accuracy than RSM. Furthermore, UPLC-QTOF-MS anal. of extracts under the optimal extraction conditions showed that there were 25 antioxidant compounds detected, 13 of which were proposed from kidney beans for the first time.

D-glucaric acid (GA) has been identified as among promising biotechnol. alternatives to oil-based chems. GA and its derivatives are widely used in food additives, dietary supplements, drugs, detergents, corrosion inhibitors and biodegradable materials. The increasing availability of a GA market is improving the cost-effectiveness and efficiency of various biosynthetic pathways. In this study, an engineered Escherichia coli strain GA10 was constructed by systematic metabolic engineering. This involved redirecting metabolic flux into the GA biosynthetic pathways, blocking the conversion pathways of D-glucuronic acid (GlcA) and GA into byproducts, introducing an in situ NAD+ regeneration system and fine-tuning the activity of the key enzyme, myo-inositol oxygenase (Miox). Subsequently, the culture medium was optimized to achieve the best performance of the GA10 strain. GA was produced at 5.35 g/L (extracellular and intracellular), with a maximized yield of ∼0.46 mol/mol on D-glucose and glycerol, by batch fermentation This work demonstrates efficient biosynthetic pathways of GA in E. coli by metabolic engineering and should accelerate the application of GA biosynthetic pathways in industrial processes.

Zhang, Qingwei; Tang, Shaohu; Li, Jianqiu; Fan, Chunfen; Xing, Libo; Luo, Keming published the artcile< Integrative transcriptomic and metabolomic analyses provide insight into the long-term submergence response mechanisms of young Salix variegata stems>, Formula: C6H10O8, the main research area is Salix variegata stem submergence integrative transcriptomics metabolomics; Oxidative stress; Phytohormones; S. variegate; Stress signaling; Submergence tolerance.

Salix variegata Franch. is a riparian shrub species that can tolerate long-term complete submergence; however, the mol. mechanisms underlying this trait remain to be elucidated. In this study, we subjected S. variegata plants to complete submergence for 60 d and collected stems to perform transcriptomic and metabolomic analyses, as well as quant. reverse transcription-polymerase chain reaction (qRT-PCR) assays. Results revealed that photosynthesis and the response to light stimulus were inhibited during submergence and recovered after desubmergence. Ethylene and abscisic acid (ABA) signaling could be important for the long-term submergence tolerance of S. variegata. Jasmonic acid (JA) signaling also participated in the response to submergence. Raffinose family oligosaccharides, highly unsaturated fatty acids, and specific stress-related amino acids accumulated in response to submergence, indicating that they may protect plants from submergence damage, as they do in response to other abiotic stressors. Several organic acids were produced in S. variegata plants after submergence, which may facilitate coping with the toxicity induced by submergence. After long-term submergence, cell wall reorganization and phenylpropanoid metabolic processes (the synthesis of specific phenolics and flavonoids) were activated, which may contribute to long-term S. variegata submergence tolerance; however, the detailed mechanisms require further investigation. Several transcription factors (TFs), such as MYB, continuously responded to submergence, indicating that they may play important roles in the responses and adaptation to submergence. Genes related to oxidative stress tolerance were specifically expressed after desubmergence, potentially contributing to recovery of S. variegata plants within a short period of time.

Luo, Jinlei; Hu, Kai; Qu, Fengfeng; Ni, Dejiang; Zhang, Haojie; Liu, Siyi; Chen, Yuqiong published the artcile< Metabolomics Analysis Reveals Major Differential Metabolites and Metabolic Alterations in Tea Plant Leaves (Camellia sinensis L.) Under Different Fluorine Conditions>, HPLC of Formula: 87-73-0, the main research area is Camellia leaf metabolite fluorine metabolomics.

Abstract: Tea plant (Camellia sinensis L.) is capable of accumulating a large amount of fluorine (F) in leaves without showing toxicity symptoms and thus offers a good model for exploring F tolerance mechanisms. Here, gas chromatog. time-of-flight mass spectrometry (GC-TOF-MS) was used to investigate metabolic changes in leaves of tea seedlings under control (0 mM), low F (0.2 mM) and high F (0.8 mM) conditions. Differentially changed metabolites such as galacturonic acid, lactose, fructose, malic acid, alanine were identified by the comparison among the three F treatment groups. A pathway map depicted based on the KEGG database reflected the involvement of pectin biosynthesis metabolism in F stress response. The gene expression and enzyme activity of key enzymes involved in pectin biosynthesis pathway and the content of pectic polysaccharides were increased by exogenous F treatments, indicating the promotion effect of F on the pectin biosynthesis. Pectin was also immunochem. stained in vivo using monoclonal antibody (2F4), which confirmed the increment. The increased pectin might contribute to combining the exogenous F in tea leaves. This research provided some novel insights into further research on F detoxification of plants.
