Malaguarnera, Lucia published the artcile< Influence of resveratrol on the immune response>, Electric Literature of 501-36-0 , the main research area is review resveratrol immune response; B lymphocytes; T lymphocytes; immune response; macrophages; natural killer; resveratrol.

A review. Resveratrol is the most well-known polyphenolic stilbenoid, present in grapes, mulberries, peanuts, rhubarb, and in several other plants. Resveratrol can play a beneficial role in the prevention and in the progression of chronic diseases related to inflammation such as diabetes, obesity, cardiovascular diseases, neurodegeneration, and cancers among other conditions. Moreover, resveratrol regulates immunity by interfering with immune cell regulation, proinflammatory cytokines’ synthesis, and gene expression. At the mol. level, it targets sirtuin, adenosine monophosphate kinase, nuclear factor- κB, inflammatory cytokines, anti-oxidant enzymes along with cellular processes such as gluconeogenesis, lipid metabolism, mitochondrial biogenesis, angiogenesis, and apoptosis. Resveratrol can suppress the toll-like receptor (TLR) and pro-inflammatory genes’ expression. The antioxidant activity of resveratrol and the ability to inhibit enzymes involved in the production of eicosanoids contribute to its anti-inflammation properties. The effects of this biol. active compound on the immune system are associated with widespread health benefits for different autoimmune and chronic inflammatory diseases. This review offers a systematic understanding of how resveratrol targets multiple inflammatory components and exerts immune-regulatory effects on immune cells.

Gholinejad, Mohammad; Dasvarz, Neda; Shojafar, Mohammad; Sansano, Jose M. published the artcile< Starch functionalized creatine for stabilization of gold nanoparticles: Efficient heterogeneous catalyst for the reduction of nitroarenes>, Quality Control of 5344-90-1, the main research area is starch creatine stabilization gold nanoparticle catalyst reduction nitroarene.

Selective reduction of nitroarom. pollutants into amines with recoverable and reusable heterogeneous catalysts is highly desirable. Herein, we prepared and characterized an efficient novel catalyst comprising 4 nm size Au nanoparticles supported on creatine modified starch. Using this catalyst, efficient reduction of nitroarenes into amines at room temperature in aqueous media was achieved. The presence of creatine in the structure of the catalyst plays important role in amount of Au loading, efficiency of the catalyst, recycling times, and leaching of Au compared to starch supported Au without creatine.

Khan, M. A.; Al-Attas, Tareq A.; Yasri, Nael G.; Zhao, Heng; Larter, Stephen; Hu, Jinguang; Kibria, Golam Md published the artcile< Techno-economic analysis of solar-powered biomass electrolysis pathway for coproduction of hydrogen and value-added chemicals>, Formula: C6H10O8, the main research area is hydrogen techno economic analysis solar biomass electrolysis.

Electrochem. oxidation of biomass to fuels and value-added chems. represents an emerging strategy for storing renewable energy and achieving a higher grade of sustainability in chem. industries. While research is still in its infancy, it is important to analyze the economic feasibility of such a process. In this study, we present a detailed techno-economic anal. (TEA) of a potential photo-biorefinery approach for sunlight-driven electro-oxidation of glucose to produce valuable fuels and chems. i.e., H2, gluconic acid (GNA) and glucaric acid (GRA). Under a base case scenario, the results are promising with a min. selling price (MSP) of GRA at $6.94 per kg, which will be ~70% lower than the current market price. The detailed breakdown and sensitivity anal. suggest that unlike conventional water electrolysis, the cost of raw materials and separation has a significant impact on the economics. Furthermore, we also establish performance targets for conversion (90%), selectivity (90%), feed concentration (0.5 M) and operating c.d. (0.4 A cm-2) such that if these targets are achieved, photo-electrochem. conversion of biomass to fuels and chems. can become a very profitable option with a MSP of GRA as low as $1.42 per kg.

Liu, Yinglong; Hou, Wenpeng; Jin, Jie; Christensen, Michael J.; Gu, Lijun; Cheng, Chen; Wang, Jianfeng published the artcile< Epichloe gansuensis increases the tolerance of Achnatherum inebrians to low-p stress by modulating amino acids metabolism and phosphorus utilization efficiency>, Formula: C6H10O8, the main research area is Epichloe Achnatherum growth phosphorus amino acid; Epichloë gansuensis; grass; low P stress; metabolomics.

In the long-term evolutionary process, Achnatherum inebrians and seed-borne endophytic fungi, Epichloe gansuensis, formed a mutually beneficial symbiosis relationship, and Epichloe gansuensis has an important biol. role in improving the tolerance of host grasses to abiotic stress. In this work, we first assessed the effects of Epichloe gansuensis on dry weight, the content of C, N, P and metal ions, and metabolic pathway of amino acids, and phosphorus utilization efficiency (PUE) of Achnatherum inebrians at low P stress. Our results showed that the dry weights, the content of alanine, arginine, aspartic acid, glycine, glutamine, glutamic acid, L-asparagine, lysine, phenylalanine, proline, serine, threonine, and tryptophan were higher in leaves of Epichloe gansuensis-infected (E+) Achnatherum inebrians than Epichloe gansuensis-uninfected (E-) Achnatherum inebrians at low P stress. Further, Epichloe gansuensis increased C content of roots compared to the root of E- plant at 0.01 mM P and 0.5 mM P; Epichloe gansuensis increased K content of leaves compared to the leaf of E- plant at 0.01 mM P and 0.5 mM P. Epichloe gansuensis reduced Ca content of roots compared to the root of E- plant at 0.01 mM P and 0.5 mM P; Epichloe gansuensis reduced the content of Mg and Fe in leaves compared to the leaf of E- plant at 0.01 mM P and 0.5 mM P. In addition, at low P stress, Epichloe gansuensis most probably influenced aspartate and glutamate metabolism; valine, leucine, and isoleucine biosynthesis in leaves; and arginine and proline metabolism; alanine, aspartate, and glutamate metabolism in roots. Epichloe gansuensis also affected the content of organic acid and stress-related metabolites at low P stress. In conclusion, Epichloe gansuensis improves Achnatherum inebrians growth at low P stress by regulating the metabolic pathway of amino acids, amino acids content, organic acid content, and increasing PUE.

Sebastiana, M.; Gargallo-Garriga, A.; Sardans, J.; Perez-Trujillo, M.; Monteiro, F.; Figueiredo, A.; Maia, M.; Nascimento, R.; Silva, M. Sousa; Ferreira, A. N.; Cordeiro, C.; Marques, A. P.; Sousa, L.; Malho, R.; Penuelas, J. published the artcile< Metabolomics and transcriptomics to decipher molecular mechanisms underlying ectomycorrhizal root colonization of an oak tree>, Computed Properties of 492-62-6, the main research area is metabolomic transcriptomic decipher mol mechanism ectomycorrhizal root colonization oak.

Mycorrhizas are known to have a pos. impact on plant growth and ability to resist major biotic and abiotic stresses. However, the metabolic alterations underlying mycorrhizal symbiosis are still understudied. By using metabolomics and transcriptomics approaches, cork oak roots colonized by the ectomycorrhizal fungus Pisolithus tinctorius were compared with non-colonized roots. Results show that compounds putatively corresponding to carbohydrates, organic acids, tannins, long-chain fatty acids and monoacylglycerols, were depleted in ectomycorrhizal cork oak colonized roots. Conversely, non-proteogenic amino acids, such as gamma-aminobutyric acid (GABA), and several putative defense-related compounds, including oxylipin-family compounds, terpenoids and B6 vitamers were induced in mycorrhizal roots. Transcriptomic anal. suggests the involvement of GABA in ectomycorrhizal symbiosis through increased synthesis and inhibition of degradation in mycorrhizal roots. Results from this global metabolomics anal. suggest decreases in root metabolites which are common components of exudates, and in compounds related to root external protective layers which could facilitate plant-fungal contact and enhance symbiosis. Root metabolic pathways involved in defense against stress were induced in ectomycorrhizal roots that could be involved in a plant mechanism to avoid uncontrolled growth of the fungal symbiont in the root apoplast. Several of the identified symbiosis-specific metabolites, such as GABA, may help to understand how ectomycorrhizal fungi such as P. tinctorius benefit their host plants.
