Cottonseed oil is recognized as an important oil in food industry for its unique characters: low flavor reversion and the high level of antioxidants (Vitamin) as well as unsaturated fatty acid. However, the cottonseed oil content of cultivated cotton (Gossypium hirsutum) is only around 20%. In this study, we modified the accumulation of oils by the down-regulation of phosphoenolpyruvate carboxylase 1 (GhPEPC1) via RNA interference in transgenic cotton plants. The qRT-PCR and enzyme activity assay revealed that the transcription and expression of GhPEPC1 was dramatically down-regulated in transgenic lines. Consequently, the cottonseed oil content in several transgenic lines showed a significant (P < 0.01) increase (up to 16.7%) without obvious phenotypic changes under filed condition when compared to the control plants. In order to elucidate the mol. mechanism of GhPEPC1 in the regulation of seed oil content, we quantified the expression of the carbon metabolism related genes of transgenic GhPEPC1 RNAi lines by transcriptome anal. This anal. revealed the decrease of GhPEPC1 expression led to the increase expression of triacylglycerol biosynthesis-related genes, which eventually contributed to the lipid biosynthesis in cotton. This result provides a valuable information for cottonseed oil biosynthesis pathway and shows the potential of creating high cottonseed oil germplasm by RNAi strategy for cotton breeding. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Safety of Methyl nonadecanoate).

Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Sea cucumbers are marine organisms with uses in food, cosmetics, and medicine. This study aimed to identify Indonesian sea cucumbers with high antioxidant and antibacterial activities. Twenty-one sea cucumber species were used for this study. Antioxidant capacity was evaluated using the 2,2-diphenyl-β-picrylhydrazine assay. Antibacterial activity was assessed using the disk diffusion assay, whereas the resazurin-based assay was employed to determine the min. inhibitory concentration (MIC) and min. bactericidal concentration (MBC). Volatile compounds possibly related to the biol. activity of sea cucumbers were analyzed via gas chromatog.-mass spectrometry (GC-MS). Holothuria atra had the strongest antioxidant capacity (IC50 = 14.22 ± 0.87 μg μL-1). Stichopus vastus displayed the best antibacterial activity against Staphylococcus aureus, whereas Stichopus ocellatus extract was most potent against Vibrio cholerae. Holothuria albiventer, which controlled Bacillus subtilis most effectively while also being active against S. aureus and V. cholerae, was the optimal antimicrobial species. H. albiventer and Actinopyga echinites inhibited B. subtilis growth at 12.5 μg μL-1. The MBC tests indicated that the antibacterial activities of sea cucumbers at the MIC were bacteriostatic, rather than bactericidal, in nature. GC-MS anal. uncovered long-chain fatty acids that might be associated with the antibacterial activities of sea cucumbers. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Application of 1731-94-8).

Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application of 1731-94-8

Adulteration of olive oil with the other cheap oils and fats plays an important role in economics and has nutritional benefits. In this work, metabolite profiling was performed using gas chromatog.-mass spectrometry to identify and quantify animal fat (lard) adulteration in vegetable oil (olive oil). Principal component anal. could correctly identify and clustering olive oil, sunflower oil, sesame oil, lard, and adulterated samples through the changes in their fatty acid Me esters (FAMEs) profile. A targeted metabolomics method was then optimized and validated through construction of calibration curves of known FAMSs in olive oil and lard. The method was presented high linearity (R² > 0.96) and good intra and inter day accuracy and precision (79-101 and 86-102% and 2-7 and 3-7, resp.) for determination of FAMEs. Afterwards the absolute concentration and relative percentage of FAMEs were successfully determined in 12 com. olive oils and 3 lards samples. Me myristate, Me palmitate, Me oleate, and Me stearate were selected as discriminant markers to identify and quantify lard adulteration even at a low level of lard (5%weight/weight), with errors less than 2% in the comparison of the absolute or relative concentrations of FAMEs using several statistical methods. The proposed methodol. allowed us to quantify the FAMEs simultaneously and also could predict small amount of lard in the adulterated olive oil samples. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Name: Methyl nonadecanoate).

The elucidation of dynamic metabolomic changes during gestation is particularly important for the development of methods to evaluate pregnancy status or achieve earlier detection of pregnancy-related complications. Some studies have constructed models to evaluate pregnancy status and predict gestational age using omics data from blood biospecimens; however, less invasive methods are desired. Here we propose a model to predict gestational age, using urinary metabolite information. In our prospective cohort study, we collected 2741 urine samples from 187 healthy pregnant women, 23 patients with hypertensive disorders of pregnancy, and 14 patients with spontaneous preterm birth. Using gas chromatog.-tandem mass spectrometry, we identified 184 urinary metabolites that showed dynamic systematic changes in healthy pregnant women according to gestational age. A model to predict gestational age during normal pregnancy progression was constructed; the correlation coefficient between actual and predicted weeks of gestation was 0.86. The predicted gestational ages of cases with hypertensive disorders of pregnancy exhibited significant progression, compared with actual gestational ages. This is the first study to predict gestational age in normal and complicated pregnancies by using urinary metabolite information. Minimally invasive urinary metabolomics might facilitate changes in the prediction of gestational age in various clin. settings.

Recently the role of protein absorption in nanoparticle drug delivery has gathered significant attention as the protein corona can significantly decide on the fate of nanoparticles in the body. Although it is known that the surface chem. will significantly influence the amount and type of bound protein, there is little known about the effect of surface roughness and surface topog. on the interaction. In this work, we show how patchy nanoparticles can noticeably reduce the adsorption of proteins compared to spherical nanoparticles with a smooth surface as demonstrated using six ABC triblock terpolymers based on glucose, mannose and galactose. As control, smooth nanoparticles were prepared from poly(2-D-sugar Et acrylate)-b-poly (Bu acrylate)-b-polystyrene (PSugEA-b-PBuA-b-PS). The patchy nanoparticles displayed significantly reduced protein absorption when exposed to serum-supplemented cell culture media, as observed using dynamic light scattering. Addnl., an enrichment of Hb was observed in the corona compared to the serum protein in solution The amount of albumin on the surface was observed to be dependent on the type of sugar with glucose resulting in the highest absorption. The protein corona led to cellular uptake that was unrelated to the underlying sugar, which was supposed to help targeting specific cell lines. This example demonstrated how the protein corona can override any attempts to target receptor expressing cells. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Quality Control of (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate).

Design of hydroxy-α-sanshool loaded nanostructured lipid carriers as a potential local anesthetic was written by Tan, Fengming;Xu, Lulu;Liu, Yanling;Li, Huan;Zhang, Dahan;Qin, Cuiying;Han, Yang;Han, Jing. And the article was included in Drug Delivery in 2022.Reference of 31566-31-1 The following contents are mentioned in the article:

Hydroxy-α-sanshool (HAS), extracted from Zanthoxylum piperitum, is commonly used in oral surgery to relief pain. However, the application of HAS is limited in clin. practice due to its poor stability. This study focuses on the design of a novel nano-formulation delivery system for HAS to improve its stability and local anesthetic effect. Hydroxy-α-sanshool loaded nanostructured lipid carriers (HAS-NLCs) were prepared by melting emulsification and ultra-sonication using monostearate (GMS) and oleic acid (OA) as lipid carriers, and poloxamer-188 (F68) as a stabilizer. Besides, the formulation was optimized by response surface methodol. (RSM). Then, the best formulation was characterized for particle size, polydispersity index (PDI), zeta potential, entrapment efficiency (EE%), drug loading (DL%), differential scanning calorimetry (DSC), and morphol. (transmission electron microscopy, TEM). The obtained HAS-NLCs were homogeneous, near spherical particles with high DL% capacity. The stability of HAS-NLCs against oxygen, light, and heat was greatly improved over 10.79 times, 3.25 times, and 2.09 times, resp., compared to free HAS. In addition, HAS-NLCs could exhibit sustained release in 24 h following a double-phase kinetics model in vitro release study. Finally, HAS-NLCs had excellent anesthetic effect at low dose in formalin test compared with free HAS and lidocaine, which indicated HAS-NLCs were a potential local anesthesia formulation in practice. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).

The objective of this study is to use response surface methodol. to forecast the performance, combustion, and emission characteristics of an advanced injection strategy-assisted diesel engine running on waste frying oil Me ester. The experiment was carried out on a diesel engine using a high-pressure fuel injection system. The main injection timing ranges varied from 16 to 24 °CA bTDC, whereas the post-injection ranges from -6 °CA bTDC to 6 °CA aTDC. The injection quantity for the main and post injections quantity varied from 70 % to 90 %, 10 % to 30 %, and the injection pressure is set at 500 bar. Experiments were carried out using a design matrix developed by the design of experiments At 100 % load, B100-90 %-10 % obtained the highest BTE of 33.87 % and the lowest fuel consumption of 0.268 kg/kW-hr. At the main injection timing of 22 °CA and post-injection timing of -4 °CA, D100-80 %-20 % achieved the lowest unburned hydrocarbon, Smoke emission of 13 ppm, and 1.613 FSN resp. The point prediction approach was used to forecast the combustion and emission parameters of a diesel engine, and the predicted results were in good agreement with the exptl. results. Furthermore, when compared to advance injection timing for biodiesel fuel, retarded injection timing reduces nitric oxide emission. The Split injection strategy is one of the most effective techniques to reduce soot and NO_x emissions while maintaining diesel engine efficiency.

Anodic Reactivity of Alkyl S-Glucosides was written by Deore, Bhavesh;Ocando, Joseph E.;Pham, Lan D.;Sanhueza, Carlos A.. And the article was included in Journal of Organic Chemistry in 2022.Electric Literature of C16H22O11 The following contents are mentioned in the article:

A voltammetric study of a series of alkyl and aryl S-glucosides unveiled the reactivity patterns of alkyl S-glucosides toward anodic oxidation and found noteworthy differences with the trends followed by aryl derivatives The oxidation potential of alkyl S-glucosides, estimated herein from square-wave voltammetry peak potentials (E_p), depends on the steric properties of the aglycon. Glucosides substituted with bulky groups exhibit E_p values at voltages more pos. than the values of those carrying small aglycons. This relationship, observed in all analyzed alkyl series, is evidenced by good linear correlations between E_p and Taft’s steric parameters (E_S) of the resp. alkyl substituents. Moreover, the role of the aglycon’s steric properties as a primary reactivity modulator is backed by poor correlations between E_p and the radical stabilization energies (RSEs) of the aglycon-derived thiyl radicals (RS•). In contrast, aryl glucosides’ E_p values exhibit excellent correlations with the aryl substituents’ Hammett parameters (σ+) and the ArS• RSEs, evidencing the inherent stability of the reactive radical intermediate as the primary factor controlling aryl glucoside’s electrochem. reactivity. The reactivity differences between alkyl and aryl S-glucosides also extend to the protective group’s effect on E_p. Alkyl S-glucosides’ reactivity proved to be more sensitive to protective group exchange. This study involved multiple reactions and reactants, such as (2S,3R,4S,5R,6R)-6-(Acetoxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetrayl tetraacetate (cas: 604-69-3Electric Literature of C16H22O11).
