Nanomaterials (NMs) have demonstrated enormous potential to improve agricultural production Ten mg L-1 of customized manganese ferrite (MnFe2O4) NMs was selected as the optimal dose based on its outstanding effects on promoting tomato flowering and production After the foliar application before flowering, MnFe2O4 NMs increased the leaf chlorophyll content by 20 percent, and significantly upregulated the expressions of ferredoxin, PsaA, and PsbA in leaves, likely by serving as an electron donor, leading to a significant increase in photosynthesis efficiency by 13.3%. Long distance transport of sucrose was then confirmed by the upregulation of sucrose transporter SUT1 and SUT2 in NM-treated leaves and meristems. The genes associated with gibberellin biosynthesis, including GA20ox2, GA20ox3, and SIGAST, and a flowering induction gene SFT, were also significantly upregulated. Importantly, the flowering time was 13 days earlier by MnFe2O4 NMs over the control. At the reproductive stage, MnFe2O4 NMs increased pollen activity and ovule size, leading to the significant increase in fruit number per plant, single fruit weight, and fruit weight per plant by 50%, 30%, and 75%, resp. Metabolically, a significant increase of glucose-6-phosphate, phenylalanine, rutin, and ascorbic acid (vitamin C), as well as a significant decrease of tomatine and methionine, demonstrates an increased nutritional value of the tomato fruits. A verified companion field experiment showed an increase of 84.1% in total tomato production with the MnFe2O4 NM amendment. These findings provide support for the early flowering and yield improvement in nano-enabled agricultural systems.

This systematic review and meta-anal. of randomized controlled trials (RCTs) was conducted to summarize the effect of resveratrol intake on weight loss. We searched the following databases until July 2018: MEDLINE, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials. Data were pooled using the inverse variance method and expressed as standardized mean difference (SMD) with 95% confidence intervals (95% CI). Out of 831 reports, 36 RCTs were eligible for including to our meta-anal. The pooled results, using random-effects model showed that resveratrol supplementation significantly decreased body weight (SMD = -0.17; 95% CI, -0.33, -0.01; P=0.03; I2: 62.6), body mass index (BMI) (SMD = -0.20; 95% CI, -0.35, -0.05; P=0.01; I2: 60.6), fat mass (SMD = -0.32; 95% CI, -0.62, -0.03; P=0.03; I2: 77.9) and waist circumference (WC) (SMD = -0.42; 95% CI, -0.68, -0.16; P=0.001; I2: 75.2), and significantly increased lean mass (SMD=1.21; 95% CI, 0.75, 1.67; P<0.001; I2: 87.6). We found no significant effect of resveratrol administration on leptin (SMD = -0.20; 95% CI, -0.68, 0.27; P=0.40; I2: 85.3) and adiponectin levels (SMD=0.08; 95% CI, -0.39, 0.55; P=0.74; I2: 91.0). Resveratrol supplementation significantly decreased body weight in obese patients (SMD -0.43; 95% CI, -0.60, -0.26) compared with other diseases (SMD 0.02; 95% CI, -0.29, 0.33), and type 2 diabetes mellitus (SMD -0.17; 95% CI, -0.37, 0.02). Overall, the current meta-anal. demonstrated that resveratrol intake significantly reduced weight, BMI, WC and fat mass, and significantly increased lean mass, but did not affect leptin and adiponectin levels.

Dewidar, Assem A.; Sorial, George A. published the artcile< Effect of surfactin on removal of semi-volatile organic compound: Emphasis on enhanced biofiltration performance>, Recommanded Product: 2-Ethylhexan-1-ol, the main research area is surfactin semi volatile organic compound biofiltration; Biosurfactant; Biotrickling filter; Fungi; Semi-volatile organic compound (SVOC); Surfactin.

The performance of a lab-scale biotrickling filter inoculated with a mixed fungal consortium was investigated for the simultaneous abatement of 2-ethylhexanol; a hydrophobic semi-volatile organic compound, and propylene glycol monomethyl ether. The biotrickling filter performance was investigated in the presence of lipopeptide-type biosurfactant, surfactin. The effect of surfactin on the removal efficiency and elimination capacity was examined at stretched inlet loading rates: 1.04 to 15.7 and 3.2-48 g m-3 h-1 of propylene glycol monomethyl ether and 2-ethylhexanol, resp. Seeding the biotrickling filter with 50 mg L-1 of surfactin maintained high and consistent removal efficiencies of propylene glycol monomethyl ether and 2-ethylhexanol up to loading rates of 15.7 and 32 g m-3 h-1, with removal efficiencies of 98.5 and 99%, resp. Once the loading rate of 2-ethylhexanol increased to 48 g m-3 h-1, a substrate inhibition was observed, accompanied by a sudden decrease in removal efficiency from 99.2 to 62.3%. At the same loading rates, the biotrickling filter performance was improved by reseeding 100 mg L-1 of surfactin, hence, reinstated the removal efficiency of 2-ethylhexanol to 92.7% and achieving a maximum elimination capacity of 44.5 g m-3 h-1. This enhanced semi-volatile organic compounduptake rate was further confirmed by a considerable increase in reaction rate constant from 0.005 to 0.017 s-1. A batch study was also conducted at the end of the exptl. run to better understand the correlation between surfactin concentrations and the time-dependent partition coefficient of 2-ethylhexanol. Biofilm microbial community structure revealed relative abundancy of 72 and 28% of Trichoderma asperellum and Fusarium solani, resp. The findings of this study show for the first time that the removal of a semi-volatile organic compd such as 2-ethylhexanol is feasible in the presence of surfactin and hence improving the bioavailability of hydrophobic semi-volatile organic compound

Ozyilmaz, Ali Tuncay; Ozgen, Begum; Celik, Cumali published the artcile< Poly(o-aminobenzyl alcohol) films with and without organic compound on AISI 316 surface; synthesis and the corrosion performances>, Synthetic Route of 5344-90-1, the main research area is aminobenzyl alc organic compound corrosion performance.

In this work, we obtained the anticorrosive properties of polymer films (SS/PABA and SS/PABAORG) synthesized on stainless steel surface by adding an organic substance to aniline derived oaminobenzyl alc. monomer synthesis medium. Firstly, we prepared the polymer coating bath by dissolving 0.15 M o -aminobenzyl alc. monomer in the electrolyte solvent containing acetonitrile and 0.15 M LiClO4. From this bath, poly (o-aminobenzyl alc.) (PABA) film was synthesized in 30 segments by cyclic voltammetry (CV) technique at a scanning rate of 50 mV/s at a potential range of -0.20/1.80 V on the AISI 316 (SS) working electrode in contrast to the platinum electrode. For the synthesis of organic structure doped polymer film (PABA-ORG), we repeated the same synthesis process by dissolving C21H27NO2(k) (ORG) at low concentration in the same bath. We investigated the corrosion performances of bare SS, SS/PABA, and SS/PABA-ORG substrates, using open circuit potential – time, anodic polarization, and AC impedance techniques in the solution of corrosion study. As a result, we observed that the organic additive added to the synthesis medium caused changes in the synthesis behavior of PABA. Corrosion performance tests showed that PABA and PABA-ORG films increased the corrosion protection performance of the SS electrode, and we observed a reduction of the corrosion rate of the SS electrode.

Zhao, Huaibo; McMillan, Alastair J.; Constantin, Timothee; Mykura, Rory C.; Julia, Fabio; Leonori, Daniele published the artcile< Merging Halogen-Atom Transfer (XAT) and Cobalt Catalysis to Override E2-Selectivity in the Elimination of Alkyl Halides: A Mild Route toward contra-Thermodynamic Olefins>, HPLC of Formula: 627-27-0, the main research area is Merging Halogen Atom Transfer Cobalt Catalysis Elimination Alkyl Halides.

We report here a mechanistically distinct tactic to carry E2-type eliminations on alkyl halides. This strategy exploits the interplay of α-aminoalkyl radical-mediated halogen-atom transfer (XAT) with desaturative cobalt catalysis. The methodol. is high-yielding, tolerates many functionalities, and was used to access industrially relevant materials. In contrast to thermal E2 eliminations where unsym. substrates give regioisomeric mixtures, this approach enables, by fine-tuning of the electronic and steric properties of the cobalt catalyst, to obtain high olefin positional selectivity. This unprecedented mechanistic feature has allowed access to contra-thermodn. olefins, elusive by E2 eliminations.

Xiao, Miao; Yue, Xin; Xu, Ruirui; Tang, Weijun; Xue, Dong; Li, Chaoqun; Lei, Ming; Xiao, Jianliang; Wang, Chao published the artcile< Transition-Metal-Free Hydrogen Autotransfer: Diastereoselective N-Alkylation of Amines with Racemic Alcohols>, Reference of 403-41-8, the main research area is diastereoselective alkylation amines alc chiral amine synthesis; alcohols; alkylation; amines; deuterium; reaction mechanisms.

A practical method for the synthesis of α-chiral amines by alkylation of amines with alcs. in the absence of any transition-metal catalysts has been developed. Under the co-catalysis of a ketone and NaOH, racemic secondary alcs. reacted with Ellman’s chiral tert-butanesulfinamide by a hydrogen autotransfer process to afford chiral amines with high diastereoselectivities (up to >99:1) [e.g., 1-phenylethanol + (R)-(+)-tert-butanesulfinamide → I (70%, > 95:5 d.r.) in presence of acetophenone and NaOH in toluene]. Broad substrate scope and up to a 10 g scale production of chiral amines were demonstrated. The method was applied to the synthesis of chiral deuterium-labeled amines with high deuterium incorporation and optical purity, including examples of chiral deuterated drugs. The configuration of amine products is found to be determined solely by the configuration of the chiral tert-butanesulfinamide regardless of that of alcs., and this is corroborated by DFT calculations Further mechanistic studies showed that the reaction is initiated by the ketone catalyst and involves a transition state similar to that proposed for the Meerwein-Ponndorf-Verley (MPV) reduction, and importantly, it is the interaction of the sodium cation of the base with both the nitrogen and oxygen atoms of the sulfinamide moiety that makes feasible, and determines the diastereoselectivity of, the reaction.

B(C6F5)3 enables the metal-free unprecedented substrate-controlled directαstereoselective synthesis of deoxyglycosides from glycals. 2,3-UnsaturatedαO-glycoside products are obtained with deactivated glycals at 75 degrees C in the presence of the catalyst, while 2-deoxyglycosides are formed using activated glycals that bear no leaving group at C-3 at lower temperatures The reaction proceeds in good to excellent yields via concomitant borane activation of glycal donor and nucleophile acceptor. The method is exemplified with the synthesis of a series of rare and biol. relevant oligosaccharide analogs.

Duchow, Elizabeth G.; Duchow, Mark W.; Plum, Lori A.; DeLuca, Hector F. published the artcile< Vitamin D binding protein greatly improves bioactivity but is not essential for orally administered vitamin D>, Quality Control of 434-16-2, the main research area is vitaminD calcium homeostasis 7dehydrocholesterol; ultraviolet light; vitamin D; vitamin D binding protein.

Vitamin D3 is a prohormone that is essential for calcium homeostasis. It is naturally produced in the skin by UV-B (UVB) irradiation of 7-dehydrocholesterol. In the absence of skin production, vitamin D3 can also be obtained from oral sources. However, the actual biol. equivalence of naturally produced (i.e., UVB-irradiation of skin) and oral vitamin D3 has not been determined We previously identified a unique and specific transport mechanism for skin-generated vitamin D3 which requires vitamin D binding protein (DBP); a mechanism that differs from absorption and transport of oral vitamin D3. In the following report, we examined the impact of this difference on the biol. activity of vitamin D3. We report that UVB-generated vitamin D3 is more potent at raising serum calcium compared to oral vitamin D3, with the total biol. activity being twofold higher. By examining the excretion of radiolabeled vitamin D3 injected unbound or pre-bound by DBP, we attributed the increased activity of skin-generated vitamin D3 to a significant reduction in biliary excretion of DBP-bound vitamin D relative to unbound vitamin D. Thus, removal of vitamin D3 from the skin by the natural DBP system markedly improves biol. activity compared to that given orally.
