Chen, Huan-Huan published the artcileCharacterization of copper-induced-release of exudates by Citrus sinensis roots and their possible roles in copper-tolerance, SDS of cas: 97-67-6, the main research area is Citrus sinensis root copper tolerance characterization; Citrus sinensis; Copper uptake; Copper-tolerance; Root exudates; Root-induced alkalization.

Copper (Cu) excess is often observed in old Citrus orchards. Little information is available on the characterization of Cu-induced-release of root exudates and their possible roles in plant Cu-tolerance. Using sweet orange [Citrus sinensis (L.) Osbeck cv. Xuegan] seedlings as materials, we investigated the impacts of 0, 0.5, 25, 150, 350, 550, 1000, 2000 or 5000 μM CuCl2 (pH 4.8) on Cu uptake, root exudates [malate, citrate, total phenolics (TP), total soluble sugars (TSS) and total free amino acids (TFAA)], electrolyte leakage and malondialdehyde, and solution pH under hydroponic conditions; the time-course of root exudates and solution pH in response to Cu; and the impacts of protein synthesis and anion-channel inhibitors, and temperature on Cu-induced-secretion of root exudates and solution pH. About 70% of Cu was accumulated in 0 and 0.5 μM Cu-exposed roots, while over 97% of Cu was accumulated in ≤25 μM Cu-exposed roots. Without Cu, the seedlings could alkalize the solution pH from 4.8 to above 6.0. Cu-stimulated-secretion of root exudates elevated with the increment of Cu concentration from 0 to 1000 μM, then decreased or remained unchanged with the further increment of Cu concentration, while root electrolyte leakage and malondialdehyde (root-induced alkalization) increased (lessened) with the increment of Cu concentration from 0 to 5000 μM. Further anal. indicated that Cu-stimulated-secretion of root exudates was an energy-dependent process and could repressed by inhibitors, and that there was no discernible delay between the onset of exudate release and the addition of Cu. To conclude, both root-induced alkalization and Cu-stimulated-release of root exudates played a key role in sweet orange Cu-tolerance via increasing root Cu accumulation and reducing Cu uptake and phytotoxicity.

Lee, Se Hee published the artcileUnraveling microbial fermentation features in kimchi: from classical to meta-omics approaches, Formula: C4H6O5, the main research area is Leuconostoc Lactobacillus Weissella fermentation; Fermentation; Genome; Kimchi; Lactic acid bacteria; Lactobacillus; Leuconostoc; Meta-omics approaches; Weissella.

Abstract: Kimchi is a traditional Korean fermented food prepared via spontaneous fermentation by various microorganisms originating from vegetables such as kimchi cabbage, radishes, and garlic. Recent advances in meta-omics approaches that integrate metataxonomics, metagenomics, metatranscriptomics, and metabolomics have contributed to explaining and understanding food fermentation processes. Kimchi microbial communities are composed of majorly lactic acid bacteria such as Leuconostoc, Lactobacillus, and Weissella and fewer eukaryotic microorganisms and kimchi fermentation are accomplished by complex microbial metabolisms to produce diverse metabolites such as lactate, acetate, CO2, ethanol, mannitol, amino acids, formate, malate, diacetyl, acetoin, and 2, 3-butanediol, which determine taste, quality, health benefit, and safety of fermented kimchi products. Therefore, in the future, kimchi researches should be systematically performed using the meta-omics approaches to understand complex microbial metabolisms during kimchi fermentation Key points: · Spontaneous fermentation by raw material microbes gives kimchi its unique flavor. · The kimchi microbiome is altered by environmental factors and raw materials. · Through the multi-omics approaches, it is possible to accurately analyze the diversity and metabolic characteristics of kimchi microbiome and discover potential functionalities.

Huber, Matthias C. published the artcileMinimalist Protocell Design: A Molecular System Based Solely on Proteins that Form Dynamic Vesicular Membranes Embedding Enzymatic Functions, Application In Synthesis of 111-87-5, the main research area is dynamic vesicular membrane amphiphilic elastin like protein; artificial cells; biocatalysis; enzyme catalysis; protocells; synthetic biology.

Life in its mol. context is characterized by the challenge of orchestrating structure, energy and information processes through compartmentalization and chem. transformations amenable to mimicry of protocell models. Here we present an alternative protocell model incorporating dynamic membranes based on amphiphilic elastin-like proteins (ELPs) rather than phospholipids. For the first time we demonstrate the feasibility of combining vesicular membrane formation and biocatalytic activity with mol. entities of a single class: proteins. The presented self-assembled protein-membrane-based compartments (PMBCs) accommodate either an anabolic reaction, based on free DNA ligase as an example of information transformation processes, or a catabolic process. We present a catabolic process based on a single mol. entity combining an amphiphilic protein with tobacco etch virus (TEV) protease as part of the enclosure of a reaction space and facilitating selective catalytic transformations. Combining compartmentalization and biocatalytic activity by utilizing an amphiphilic mol. building block with and without enzyme functionalization enables new strategies in bottom-up synthetic biol., regenerative medicine, pharmaceutical science and biotechnol.

Lin, Yanxin published the artcileSensory and chemical characterization of Chinese bog bilberry wines using Check-all-that-apply method and GC-Quadrupole-MS and GC-Orbitrap-MS analyses, HPLC of Formula: 505-10-2, the main research area is bog bilberry wine cymene orbitrap mass spectrometry; Affective test; CATA; GC–MS; Potential odor-active compound; Sensory profile; Untrained panel; Volatile profile.

The sensory and chem. profiles of com. bog bilberry (BB) wines were investigated using a multi-anal. approach. Sensory test included scaling and check-all-that-apply (CATA) method with questions on liking of BB wine. The sensory data was correlated with their volatile compound profiles determined using gas chromatog. coupled with quadrupole and orbitrap mass spectrometry (GC-Quadrupole/Orbitrap-MS). In general, all BB wines were characterized with “”fruity””, “”blueberry”” and “”floral”” odors and “”sour””, “”mouth puckering”” and “”sweet”” flavors. Samples more frequently characterized as “”fruity”” and “”floral”” in CATA were preferred by the panelists (n = 93). High relative proportions of o-cymene, p-cymenene, 1-octen-3-one and 3-ethylphenol in a sample (described as “”ginger”” and “”chili””) resulted in a lower liking rating. Similarly, generally disliked sample described with “”Chinese herbs”” and “”licorice”” was characterized by compounds 3-methylpentan-1-ol, 1,1,6-trimethyl-1,2-dihydronaphthalene, and 4-vinylphenol. The data will give novel information for berry wine and beverage industry on the quality factors of BB wines linked to higher acceptance.

Matsumiya, Masahiko published the artcileSeparation of palladium by solvent extraction with methylamino-bis-N,N-dioctylacetamide and direct electrodeposition from loaded organic phase, Synthetic Route of 111-87-5, the main research area is palladium solvent extraction methylaminodioctylacetamide formed organic phase direct electrodeposition.

The development of solvent extraction and direct electrodeposition processes is an important task to reduce the volume of secondary wastes. In this study, the extraction of Pd(II) from hydrochloric/chloride media using methylimino-bis-N,N-dioctylacetamide (MIDOA) in three diluents (acetophenone; AP, 1,2-dichloroethane; DCE, or 1-octanol; OC) was investigated. Slope anal. revealed that the extraction reaction of Pd(II) was based on the following anion exchange: [PdCl42-]aq + n[MIDOA]org ↔ [Pd(Cl)4-2n(MIDOA)2]2n-2org + 2n[Cl-]aq . The electrochem. behavior of the extracted Pd(II) complex in the MIDOA/AP bath was investigated using an electrochem. quartz crystal microbalance (EQCM). Pd(II) was found to be reduced to Pd(0) metal via a two-electron transfer, and the cathodic reaction [Pd(MIDOA)2]2+ + 2e- → Pd(0) + 2[MIDOA] was found to proceed in the region between -2.38 V and -3.40 V based on the apparent molar mass of 105.22 evaluated by EQCM. Moreover, the alternation of Δηρ corresponded to the local decrease in the viscosity of the organic phase near the electrode. The potentiostatic electrodeposition of the extracted Pd(II) complex enabled us to recover the blackish electrodeposits, which were identified as Pd metal through SEM/EDX, XPS, and XRD analyses.

Dybczynski, Rajmund S. published the artcileSeparation of Rare Earth Elements (REE) by Ion Interaction Chromatography (IIC) Using Diglycolic Acid (ODA) as a Complexing Agent, Quality Control of 110-99-6, the main research area is separation rare earth element ion interaction chromatog; diglycolic acid complexing agent.

Abstract: The possibility of rare earth elements (REE) separation by ion interaction chromatog. (IIC) employing their complexes with diglycolic acid (ODA) in anion exchange mode has been studied theor. and exptl. Calculations, assuming that only trivalent complex is significantly uptaken by the stationary phase, indicated that at at pH 4-6, the retention in the lanthanide series should increase from La to the Tb-Dy-Ho region with yttrium showing apparent at. number (ApparatusAt.Number) of 671/2 and then decrease with further increase of at. number Chromatog. experiments in the system: Column: Eternity C18-mobile phase 5 mM ODA/8.6 mM TBAOH/0.6 mM HNO3; pH 4.60 confirmed theor. predictions. It was found that scandium at pH ≥ 4.0 elutes in front of the whole REE group but at low pH enters the region of light lanthanides. The non-monotonical change of affinity of the REE with the increase of at. number results in quite unusual order of elution of REE namely: Sc < La < Ce < Lu < Pr < Yb < Nd < Tm < Sm < Eu < Er≈Y < Gd < Ho < Tb≈Dy.

Heffernan, Michele L. R. published the artcileUlotaront: A TAAR1 Agonist for the Treatment of Schizophrenia, COA of Formula: C4H11NO2, the main research area is structure TAAR1 agonist ulotaront preparation schizophrenia.

Ulotaront (SEP-363856) is a trace-amine associated receptor 1 (TAAR1) agonist with 5-HT1A receptor agonist activity in Phase 3 clin. development, with FDA Breakthrough Therapy Designation, for the treatment of schizophrenia. TAAR1 is a G-protein-coupled receptor (GPCR) that is expressed in cortical, limbic, and midbrain monoaminergic regions. It is activated by endogenous trace amines, and is believed to play an important role in modulating dopaminergic, serotonergic, and glutamatergic circuitry. TAAR1 agonism data are reported herein for ulotaront and its analogs in comparison to endogenous TAAR1 agonists. In addition, a human TAAR1 homol. model was built around ulotaront to identify key interactions and attempt to better understand the scaffold-specific TAAR1 agonism structure-activity relationships.

Lima, Nayana F. published the artcileOral nitazoxanide treatment of experimental neurocysticercosis induces gluconeogenesis in Taenia crassiceps cysticerci, Name: (S)-2-hydroxysuccinic acid, the main research area is nitazoxanide antiprotozoal agent oral drug delivery gluconeogenesis Taenia neurocysticercosis; Experimental neurocysticercosis; Fatty acids oxidation; Metabolism; Nitazoxanide; Taenia crassiceps.

Neurocysticercosis is the most frequent helminthiasis of the central nervous system and is caused by the presence of Taenia solium cysticerci. Nitazoxanide (NTZ) is an antifolate containing the pyrrolopyrimidine-based nucleus that exerts its antiprotozoal activity due to interference with the pyruvate:ferredoxin oxidoreductase (PFOR) enzyme which is essential to anaerobic energy metabolism The aim of this work was to determine the effect of NTZ on the energetic metabolism of Taenia crassiceps cysticerci intracranially inoculated BALB /c mice. The infected animals were treated with a single oral dose of NTZ 30 days after the inoculation. Anal. of the organic acids was performed through high performance liquid chromatog. Glucose was detected only in the treated groups, alongside with a significant decrease in lactate, pyruvate and oxaloacetate concentrations which indicate an increase in gluconeogenesis. The non-detection of alpha-ketoglutarate indicated the use of the fumarate reductase pathway in all groups. It was possible to confirm the drugs mode of action due to the non-detection of acetate in the treated groups. There was an increase in the fatty acids oxidation Therefore it was possible to observe that NTZ induces gluconeogenesis as well as the increase of alternative energetic pathways such as fatty acids oxidation in T. crassiceps cysticerci.

Yasuzawa, Mikito published the artcileCharacterization of N-substituted polypyrrole thin-film electrode having immobilized glucose oxidase, SDS of cas: 50966-69-3, the main research area is polypyrrole electrode glucose oxidase.

The authors describe the properties of a glucose sensor prepared by the electropolymerization or pyrrole derivatives, 1-pyrrole propionic acid (PPA) and 1-pyrrole propanol (PPO), which have a carboxyl group and hydroxyl group, resp. Since these derivatives have substituents that can possibly make a hydrogen bond with GO, these electrodes are expected to afford higher electrode stability and reproducibility compared with that of unsubstituted pyrrole.
