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.

Teruel, Adrian H.; Perez-Esteve, Edgar; Gonzalez-Alvarez, Isabel; Gonzalez-Alvarez, Marta; Costero, Ana M.; Ferri, Daniel; Gavina, Pablo; Merino, Virginia; Martinez-Manez, Ramon; Sancenon, Felix published the artcile< Double Drug Delivery Using Capped Mesoporous Silica Microparticles for the Effective Treatment of Inflammatory Bowel Disease>, Safety of Sodium 5,5′-(diazene-1,2-diyl)bis(2-hydroxybenzoate), the main research area is silica microparticle hydrocortisone inflammatory bowel disease antiinflammatory; colon targeted release; gated materials; inflammatory bowel disease; mesoporous silica microparticles; smart drug delivery materials.

Silica mesoporous microparticles loaded with both rhodamine B fluorophore (S1) or hydrocortisone (S2), and capped with an olsalazine derivative, are prepared and fully characterized. Suspensions of S1 and S2 in water at an acidic and a neutral pH show negligible dye/drug release, yet a notable delivery took place when the reducing agent sodium dithionite is added because of hydrolysis of an azo bond in the capping ensemble. Addnl., olsalazine fragmentation induced 5-aminosalicylic acid (5-ASA) release. In vitro digestion models show that S1 and S2 solids are suitable systems to specifically release a pharmaceutical agent in the colon. In vivo pharmacokinetic studies in rats show a preferential rhodamine B release from S1 in the colon. Moreover, a model of ulcerative colitis is induced in rats by oral administration of 2,4,6-trinitrobenzenesulfonic acid (TNBS) solutions, which was also used to prove the efficacy of S2 for colitis treatment. The specific delivery of hydrocortisone and 5-ASA from S2 material to the colon tissue in injured rats markedly lowers the colon/body weight ratio and the clin. activity score. Histol. studies showed a remarkable reduction in inflammation, as well as an intensive regeneration of the affected tissues.

A review. Abstract: We have previously described new pathways of vitamin D3 activation by CYP11A1 to produce a variety of metabolites including 20(OH)D3 and 20,23(OH)2D3. These can be further hydroxylated by CYP27B1 to produce their C1α-hydroxyderivatives. CYP11A1 similarly initiates the metabolism of lumisterol (L3) through sequential hydroxylation of the side chain to produce 20(OH)L3, 22(OH)L3, 20,22(OH)2L3 and 24(OH)L3. CYP11A1 also acts on 7-dehydrocholesterol (7DHC) producing 22(OH)7DHC, 20,22(OH)27DHC and 7-dehydropregnenolone (7DHP) which can be converted to the D3 and L3 configurations following exposure to UVB. These CYP11A1-derived compounds are produced in vivo and are biol. active displaying anti-proliferative, anti-inflammatory, anti-cancer and pro-differentiation properties. Since the protective role of the classical form of vitamin D3 (1,25(OH)2D3) against UVB-induced damage is recognized, we recently tested whether novel CYP11A1-derived D3- and L3-hydroxyderivatives protect against UVB-induced damage in epidermal human keratinocytes and melanocytes. We found that along with 1,25(OH)2D3, CYP11A1-derived D3-hydroxyderivatives and L3 and its hydroxyderivatives exert photoprotective effects. These included induction of intracellular free radical scavenging and attenuation and repair of DNA damage. The protection of human keratinocytes against DNA damage included the activation of the NRF2-regulated antioxidant response, p53-phosphorylation and its translocation to the nucleus, and DNA repair induction. These data indicate that novel derivatives of vitamin D3 and lumisterol are promising photoprotective agents. However, detailed mechanisms of action, and the involvement of specific nuclear receptors, other vitamin D binding proteins or mitochondria, remain to be established.

A review. Resveratrol, found in variety of plants, is a natural stilbene structure polyphenol. It has various pharmacol. effects, such as antioxidation, anti-aging, anti-inflammation, anti-cancer, antiobesity, anti-diabetes, cardioprotection, neuroprotection. Recently, anti-leukemia activities of resveratrol has been studied extensively via its effects on a variety of biol. processes involving cell proliferation, apoptosis, autophagy. Current treatments of leukemia mainly rely on intensive chemotherapy or hematopoietic stem cell transplantation, however, these treatments are still with poor survival and high treatment-related mortality. Therefore, it is extremely needed to find relatively non-toxic medicines with minimal side effects but sufficient therapeutic efficacy. Resveratrol is one such potential candidate owing to its reported anti-leukemia effect. In this review, we summarized resveratrol’s discovery, sources and isolation methods, administration methods, effects in different types of leukemia, pharmacokinetics and toxicities, aiming to exploit resveratrol as a potential drug candidate for anti-leukemia.

Tyagi, Kamal; Maoz, Itay; Vinokur, Yakov; Rodov, Victor; Lewinsohn, Efraim; Lichter, Amnon published the artcile< Enhancement of table grape flavor by postharvest application of monoterpenes in modified atmosphere>, Name: 3,7-Dimethylocta-1,6-dien-3-ol, the main research area is postharvest monoterpene modified atm ethanol linalool geraniol.

Consumers expect ready-to-eat grapes to have excellent quality and flavor. In practise, most table grape cultivars have a neutral flavor relying mainly on the combination of sugar and acidity due to limited levels of volatiles that impart the unique aromas. This study investigated the possibility of improving grape flavor by incubating the berries in monoterpene-enriched modified atm. The berries were sanitized by dipping in ethanol and packaged in trays sealed with plastic films of different perforation levels. The optimal conditions selected for further study were one micro-perforation per package containing 250 g berries and storage at 5°C for 2 wk. To test the possibility of improving grape flavor during storage, berries of the cultivars Flame Seedless, Adominique, 4111 and Crimson Seedless were stored in the presence of the monoterpenes linalool or geraniol. After two weeks of storage in the presence of linalool, it accumulated in the berries to levels of 551, 704 and 3273μg kg-1 in Adominique, 4111 and Crimson Seedless, resp. Application of linalool or geraniol resulted in appearance of many other monoterpenes, probably by the action of endogenous enzymes. Organoleptic preference assays indicated that berries of Adominique and 4111 stored in the presence of linalool were favored over the control berries. Overall, the results demonstrate the feasibility of using monoterpenes to enhance berry flavor during storage.
