Xu, Minwei published the artcileHS-SPME-GC-MS/olfactometry combined with chemometrics to assess the impact of germination on flavor attributes of chickpea, lentil, and yellow pea flours, Application of n-Octanol, the main research area is germination chickpea lentil pea; (E,E)-2,4-decadienal (PubChemCID: 5283349); (E,E)-2,4-nonadienal (PubChemCID: 5283339); 1-Hexanol (PubChemCID: 8103); 2-Pentyl-furan (PubChemCID: 19620); 3-Methyl-1-butanol (PubChemCID: 31260); Beany flavor; Chemometric; Germination; Gluten-free; Hexanal; Hexanal (PubChemCID: 6184); Pulse.

In this study, volatile component changes of germinated chickpea, lentil, and yellow pea flours over the course of 6 days germination were characterized by HS-SPME-GC-MS/O. In total, 124 volatile components were identified involving 19 odor active components being recorded by GC-O exclusively. Principal component anal. (PCA) and hierarchical cluster anal. (HCA) revealed that lentil and yellow pea flours had the similar aromatic attributes, while the decrease of beany flavor compounds along with the occurrence of unpleasant flavors was detected in chickpea flours upon germination. Six beany flavor markers, including hexanal, (E,E)-2,4-nonadienal, (E,E)-2,4-decadienal, 3-methyl-1-butanol, 1-hexanol, and 2-pentyl-furan, were employed to quantify beany flavor formation in the flours over the course of germination. The results suggested that no significant beany flavor formation or mitigation was appeared after 1 day of germination. The findings are crucial for tailing pulse germination process to enhance the macronutrients without increasing undesirable beany flavor.

Sharma, Manish published the artcileA significant increase in rhizosheath carboxylates and greater specific root length in response to terminal drought is associated with greater relative phosphorus acquisition in chickpea, HPLC of Formula: 97-67-6, the main research area is Cicer arietinum rhizosheath carboxylate root drought phosphorus.

We investigated the effects of water stress under low phosphorus (P) supply on P-acquisition by chickpea, and identified a genotype with faster relative growth and P-acquisition rates. We grew four genotypes in pots filled with a sand and soil mixture with a low P availability in a glasshouse. Plants were either well-watered or water-stressed, imposed at the reproductive stage. Plants were harvested when water-stressed plants fully closed their stomata. For all four genotypes, water stress reduced shoot and root growth, root mass ratio, and shoot P content, while it increased specific root length (except in ICC 456), water-use efficiency and the amount of rhizosheath carboxylates per g root dry weight A faster relative shoot P-acquisition rate in ICC 2884 was associated with a greater specific root length, a smaller mean root diameter and a greater increase in the amount of rhizosheath carboxylates in response to water stress under low P supply. Interestingly, under water stress ICC 2884 also maintained a similar physiol. P-use efficiency to that of the well-watered plants. ICC 2884 is recommended as a parental genotype in chickpea breeding programs to develop cultivars for low-P and terminal drought environments.

Khatouri, M. published the artcileSol/gel transition of oil/water microemulsions controlled by surface grafted triblock copolymer dodecyl-PEO227-dodecyl: molecular dynamics simulations with experimentally validated interaction potential, Recommanded Product: n-Octanol, the main research area is soluble gel transition microemulsion copolymer mol dynamic simulation.

We studied a large range of identical spherical oil/water microemulsion (O/W-MI) volume fractions. The O/W-MIs are stabilized by cetylpyridinium chloride ionic surfactant (CpCl) and octanol cosurfactant and dispersed in salt water. We grafted different numbers of dodecyl-(polyEthylene oxide)227-dodecyl triblock copolymer that we note (n(D-PEO227-D)), where n varies from 0 to 12. We accomplished the grafting process by replacing a small amount of CpCl and octanol with the appropriate n(D-PEO227-D). The aim is to determine the interaction/structure relationship of the covered microemulsions. Precisely, we are interested in a quant. investigation of the influence of volume fraction Φ, temperature (T), and n(D-PEO227-D) on the microemulsion sol/gel transition. To this end, we first study the uncoated microemulsion structure depending only on Φ. Second, we determine the coated microemulsions structure as a function of n(D-PEO227-D) for different Φ. Third, we examine the effect of temperature on the uncoated and coated microemulsion. We show that the sol/gel transition is controlled by the three main parameters, Φ, T, and n(D-PEO227-D). Accordingly, the uncoated microemulsion sol/gel transition, at ambient temperature, occurred for Φ ≃ 33.65%. By increasing Φ, the O/W-MIs show a glass state, which occurs, along with the gel state, at Φ ≃ 37% and arises clearly at Φ ≃ 60%. The coated O/W-MI sol/gel transition is found to be linearly dependent on n(D-PEO227-D) and takes place for Φ ≃ 26.5% for n(D-PEO227-D) = 12. Ordinarily, the decrease in temperature leads to gel formation of microemulsions for low Φ. Addnl., in this work, we found that the gelation temperature increases linearly with n(D-PEO227-D). Thus, the parameter n(D-PEO227-D) can control the sol/gel transition of the O/W-MIs at ambient temperature and moderate Φ.

Yoshimura, Yukihiro published the artcileRaman investigation on the local structure of alcohols in 1-butyl-3-methylimidazolium tetrafluoroborate, Application In Synthesis of 111-87-5, the main research area is alc ionic liquid hydrogen bond cluster Raman spectra conformation.

In this study, we investigated the evolution of the local structure of a series of primary alcs. from methanol to octanol in 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) as a function of alc. concentration using Raman spectroscopy, with the aim of gaining more insight into the fundamentals of the compelling ionic liquid-mol. solvent interactions at mol. level. The Raman spectra revealed the presence of various types of O-H species in the mixtures, with the major fractions at low alc. concentration corresponding to monomers, which indicates that most of the alc. mols. are isolated from each other. A plausible picture for the changes in the local structures of alc. mols. loosely confined in the [bmim][BF4] matrix is presented, which suggests the occurrence of conformational changes in the bmim+ cation and the alc. mols. This observation may indicate a unique evolution of the local structure of alc. clusters formed in the ionic liquid

Yoshimura, Yukihiro published the artcileAn insight into the filling of the nanoheterogeneous structures of1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide by primary alcohols, COA of Formula: C8H18O, the main research area is ionic liquid alc hydrogen bond cluster Raman spectra conformation.

Mixtures of ionic liquids (ILs) with mol. cosolvents are attracting increased attention for the development of their technol. applications. As a result, understanding the interaction between the heterogeneous structure of ILs and mol. cosolvents at a microscopic level with the aim of fine-tuning the properties of ILs is of utmost importance. In this study, the local structure of the IL 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide ([bmim][TFSA]) in a series of mixtures of primary alc. (from methanol to 1-dodecanol) is investigated as a function of alc. concentration by Raman spectroscopy, providing a unique picture of the evolution of the local structure of alc. clusters formed in [bmim][TFSA]. The Raman spectra reveal the presence of various types of O-H species in the [bmim][TFSA]-alc. mixtures, with the major fractions corresponding to monomers at lower alc. concentrations Presented in this study is a plausible mechanism for the filling of the nanoheterogeneous structures of the [bmim][TFSA] matrix by alc. mols., revealing the occurrence of conformational changes in the bmim+ cation and TFSA- anion, which involves an increase of the population of the gauche and transoid conformers with alc. concentration Interestingly, the results show that the local structures of bmim+ and TFSA- cooperatively change along with the conformational change in the alc. mols. toward a smaller total volume

Worawit, Chanatda published the artcileCombining graphite with hollow-fiber liquid-phase microextraction for extraction of polar organic compounds, Quality Control of 111-87-5, the main research area is graphite hollow fiber liquid phase microextraction extraction polar; organic compound water sample analysis; Carbon nanosorbent; Gas chromatography; Graphite; Hollow-fiber liquid-phase microextraction; Nanomaterial; Trihalomethane.

In this study, we have developed a simple and effective hybrid extraction method based on the incorporation of raw carbon nanosorbents and octanol in the pores of a hollow-fiber membrane for improving the extraction efficiency of relatively polar organic compounds Trihalomethanes (THMs) were used as model analytes. Three types of carbon nanosorbents (graphite, graphene, and multi-walled carbon nanotubes) were studied. The carbon sorbent incorporating membrane was used in a two-phase mode liquid-phase microextraction, with 1-octanol as the acceptor solution Using a graphite-reinforced hollow-fiber membrane and an extraction time of 10 min, enrichment factors of 40-71 were obtained for trichloromethane, bromodichloromethane, bromoform, and chlorodibromomethane. Linear working ranges of 0.2-100μg L-1 and limits of detection ranging from 0.01μg L-1 (for CHCl2Br and CHClBr2) to 0.1μg L-1 (for CHCl3) were achieved. The min. detectable concentrations were far below the maximum concentration levels (60-200μg L-1) set by the WHO for drinking water. The carbon-sorbent-reinforced hollow-fiber liquid-phase microextraction afforded higher extraction efficiency and shorter extraction time compared with conventional hollow-fiber liquid-phase microextraction Finally, the method was applied to the anal. of real water samples, such as drinking water, tap water, and swimming pool water samples.

Hansen, Camilla published the artcileHigh metabolic substrate load induces mitochondrial dysfunction in rat skeletal muscle microvascular endothelial cells, Formula: C4H6O5, the main research area is mitochondrial dysfunction rat skeletal muscle microvascular endothelial cell; glucose; mitochondria; palmitic acid; reactive oxygen species; respirometry; vascular.

The influence of glucose and palmitic acid (PA) on mitochondrial respiration and emission of hydrogen peroxide (H2O2) was determined in skeletal muscle-derived microvascular endothelial cells. Measurements were assessed in intact and permeabilized (cells treated with 0.025% saponin) low passage endothelial cells with acute-or prolonged (3 days) incubation with regular (1.7 mM) or elevated (2.2 mM) PA concentrations and regular (5 mM) or elevated (11 mM) glucose concentrations In intact cells, acute incubation with 1.7 mM PA alone or with 1.7 mM PA + 5 mM glucose (p < .001) led to a lower mitochondrial respiration (p < 0.01) and markedly higher H2O2/O2 emission (p < 0.05) than with 5 mM glucose alone. Prolonged incubation of intact cells with 1.7 mM PA +5 mM glucose led to 34% (p < 0.05) lower respiration and 2.5-fold higher H2O2/O2 emission (p < 0.01) than incubation with 5 mM glucose alone. Prolonged incubation of intact cells with elevated glucose led to 60% lower (p < 0.05) mitochondrial respiration and 4.6-fold higher H2O2/O2 production than incubation with 5 mM glucose in intact cells (p < 0.001). All effects observed in intact cells were present also in permeabilized cells (State 2). In conclusion, our results show that acute and prolonged lipid availability, as well as prolonged hyperglycemia, induces mitochondrial dysfunction as evidenced by lower mitochondrial respiration and enhanced H2O2/O2 emission. Elevated plasma substrate availability may lead to microvascular dysfunction in skeletal muscle by impairing endothelial mitochondrial function.

Corey, Elizabeth A. published the artcileInhibitory signaling in mammalian olfactory transduction potentially mediated by Gαo, Computed Properties of 111-87-5, the main research area is mammalian olfactory receptor neuron inhibition modulation transduction; Combinatorial coding; Inhibition; Modulation; Olfaction; Olfactory receptor neurons.

Olfactory GPCRs in mammalian olfactory receptor neurons mediate excitation through the Gαs family member Gαolf. Here we tentatively associate a second G protein, Gαo, with inhibitory signaling in mammalian olfactory transduction by first showing that odor evoked phosphoinositide 3-kinase-dependent inhibition of signal transduction is absent in the native ORNs of mice carrying a conditional OMP-Cre based knockout of Gαo. We then identify an OR from native rat ORNs that are activated by octanol through cyclic nucleotide signaling and inhibited by citral in a PI3K-dependent manner. We show that the OR activates cyclic nucleotide signaling and PI3K signaling in a manner that reflects its functionality in native ORNs. Our findings lay the groundwork to explore the interesting possibility that ORs can interact with two different G proteins in a functionally identified, ligand-dependent manner to mediate opponent signaling in mature mammalian ORNs.

Locci, Emanuela published the artcileMetabolomics improves the histopathological diagnosis of asphyxial deaths: an animal proof-of-concept model, Recommanded Product: (S)-2-hydroxysuccinic acid, the main research area is metabolome histopathol diagnosis asphyxial death.

The diagnosis of mech. asphyxia remains one of the most difficult issues in forensic pathol. Asphyxia ultimately results in cardiac arrest (CA) and, as there are no specific markers, the differential diagnosis of primitive CA and CA secondary to asphyxiation relies on circumstantial details and on the pathologist experience, lacking objective evidence. Histol. examination is currently considered the gold standard for CA post-mortem diagnosis. Here we present the comparative results of histopathol. vs. those previously obtained by 1H NMR (NMR) metabolomics in a swine model, originally designed for clin. purposes, exposed to two different CA causes, namely ventricular fibrillation and asphyxia. While heart and brain microscopical anal. could identify the damage induced by CA without providing any addnl. information on the CA cause, metabolomics allowed the identification of clearly different profiles between the two groups and showed major differences between asphyxiated animals with good and poor outcomes. Minute-by-minute plasma sampling allowed to associate these modifications to the pre-arrest asphyxial phase showing a clear correlation to the cellular effect of mech. asphyxia reproduced in the experiment The results suggest that metabolomics provides addnl. evidence beyond that obtained by histol. and immunohistochem. in the differential diagnosis of CA.

Wang, Chao published the artcileRobust hydrogen production via pickering interfacial catalytic photoreforming of n-octanol-water biphasic system, COA of Formula: C8H18O, the main research area is hydrogen production octanol water pickering interfacial catalysis; Pt/TiO2 nanosheets; hydrogen production; microfluidics; photoreforming; pickering interfacial catalysis.

Pickerin g emu lsion offers a promis ing platform for conductin g interfa cial reaction s bet ween immis cible reagents ; it is part icularly suit able for hy drogen producti on by photo reforming of non-w ater soluble biomass liq uid and w ater. Here in, Pt-p romoted (001)-fa cet-domi nated anatase TiO2 nanosheets were synthesized by a hydrothermal route associated with microfluidic technol. for high activity and metal dispersion, and selective surface modification was carried out for preparing Janus particles. Photoreforming hydrogen production through n-octanol and water that formed O/W microemulsion with an average diameter of 540μm was achieved to obtain amphiphilic catalyst. The as-prepared 2D Janus-type catalysts exhibited remarkably stable emulsification performance as well as photocatalytic activity. This finding indicates that triethoxyfluorosilane had negligible impact on the catalytic performance, yet provided a remarkable benefit to large sp. surface area at microemulsion interface, thereby enhancing the H2 yield up to 2003μmol/g. The cyclic experiments indicate that the decrease in cyclic performance was more likely to be caused by the coalescence of the microemulsion rather than the decrease in catalytic activity, and the microemulsion could be easily recovered by simply hand shaking to more than 96% of the initial performance.
