The research results were published in《Colloids and Surfaces, B: Biointerfaces》 in 2021.SDS of cas: 112-84-5 The article conveys some information:

Marine biofouling of ship hulls and ocean structures causes enormous economic losses due to increased frictional drag. Thus, efforts have been exerted worldwide to eliminate biofouling. In addition, a strong demand exists for the development of a cost-effective and eco-friendly anti-biofouling coating technol. Thus, erucamide-polydimethylsiloxane (EP) coating is proposed in this study. EP exhibits a hydrophobic surface as the erucamide content and drag reduction effect increase. In this study, the drag reduction effect of the EP 2.5 is better than that of glass and polydimethylsiloxane (PDMS) surfaces. Moreover, the proposed EP coatings are observed to prevent the biofouling induced by bacteria (E. coli) and brown algae (Cladosiphon sp.). In addition, through a marine field test, the anti-biofouling effect of the EP surface is found to be better than the previously studied oleamide-PDMS (OP) surface. In the marine field test, the EP 2.5 demonstrates superior anti-biofouling performance for 5.5 mo under real marine environment. The proposed eco-friendly EP coating method could be applicable to marine vehicles that require effective drag reduction and anti-biofouling properties.cis-13-Docosenamide (cas: 112-84-5) were involved in the experimental procedure.

The research results were published in《Journal of Agricultural and Food Chemistry》 in 2022.HPLC of Formula: 112-84-5 The article conveys some information:

The chems. in food contact materials (FCMs) can migrate into food and endanger human health. In this study, we developed a database of traveling wave collision cross section in nitrogen (^TWCCS_N2) values for extractables and leachables from FCMs. The database contains a total of 1038 ^TWCCS_N2 values from 675 standards including those commonly used additives and nonintentionally added substances in FCMs. The ^TWCCS_N2 values in the database were compared to previously published values, and 85.7, 87.7, and 64.9% [M + H]⁺, [M + Na]⁺, and [M – H]^– adducts showed deviations <2%, with the presence of protomers, post-ion mobility spectrometry dissociation of noncovalent clusters and inconsistent calibration are possible sources of CCS deviations. Our exptl. ^TWCCS_N2 values were also compared to CCS values from three prediction tools. Of the three, CCSondemand gave the most accurate predictions. The ^TWCCS_N2 database developed will aid the identification and differentiation of chems. from FCMs in targeted and untargeted anal. To complete the study, the researchers used cis-13-Docosenamide (cas: 112-84-5) .

Knolhoff, Ann M.;Premo, Jacob H.;Fisher, Christine M. published 《A Proposed Quality Control Standard Mixture and Its Uses for Evaluating Nontargeted and Suspect Screening LC/HR-MS Method Performance》. The research results were published in《Analytical Chemistry (Washington, DC, United States)》 in 2021.HPLC of Formula: 112-84-5 The article conveys some information:

Nontargeted (NTA) and suspect screening analyses (SSA) aim to detect and identify unknown compounds of interest from a given sample. The complexity and diversity of NTA and SSA methodologies necessitate the use of a comprehensive quality control standard mixture to determine if methods are fit for purpose, but to our knowledge, such a standard has not been developed that can be used by multiple disciplines, nor is one readily available. This work describes the development and anal. of a proposed nontargeted standard/quality control mixture for NTA and SSA applications using liquid chromatog./electrospray ionization-high resolution-mass spectrometry. Considerations in its development included achieving diversity of compounds with respect to elemental composition, mol. weight, retention time, and ionization in pos. and/or neg. ion modes, which resulted in the inclusion of 89 compounds The utility of the standard mixture was applied on our own NTA and SSA workflows where sample preparation efficiency and potential sources of error due to instrumental and data processing methods were evaluated. Some areas in need of improvement were identified, such as hydrophilic compound detection and mol. formula generation for compounds containing fluorine. However, our overall methodol. was found to be fit for purpose and we were able to establish thresholds to increase reliability and throughput of reported results. And cis-13-Docosenamide (cas: 112-84-5) was used in the research process.

The research results were published in《Journal of Ethnopharmacology》 in 2021.Recommanded Product: cis-13-Docosenamide The article conveys some information:

Nepeta adenophyta Hedge (Lamiaceae) is an endemic therapeutic herb from Astore, Gilgit (Pakistan). This plant species has been reported among the local communities, especially for treating abdominal pain, kidney pain, menstrual pain, headache, and controlling bleeding disorders. Therefore, the scientific basis is provided for the relief of pain as it is used in various pain management among the natives, especially as ethnogynecol. herbal remedy. The present study investigates the analgesic and anti-inflammatory effects of the ethanolic extract of N. adenophyta in animal models. Furthermore, the extract was also studied to determine their valuable phytoconstituents. The biol. effects were determined via tail-flick, hot plate, and acetic-acid-induced abdominal writhing methods. At the same time, anti-inflammatory activity was assesed via oxidative burst and antioxidant DPPH assay. Gas chromatog.-mass spectrometry (GC-MS), and liquid chromatog.-mass spectrometry (LC-MS) techniques were employed to understand the phytochems. present in the crude ethanolic extract of Nepeta adenophyta. In the current study, Nepeta adenophyta extract exhibited potent analgesic and anti-inflammatory effects on different pain models and indicated that the analgesic effect of N. adenophyta extract is mediated both in central and peripheral ways. Dose-dependent and significant (P < 0.05) increases were shown in pain threshold, at 45 min post-treatment, with 20 and 40 mg/kg of the extract in the tail-flick model. The effects of the extract were similar to aspirin but lower to those by morphine (2.5 mg/kg) in the same tests. The extract (20-40 mg/kg) showed dose-dependent inhibition of writhing with a significant (P < 0.001) increase protection against thermal stimuli in hot plate test as compared to control and similar to aspirin and morphine. Further, the anti-inflammatory activity of the crude in oxidative burst and DPPH assays showed significant inhibitory activity. The chem. profile anal. showed major phytochems., including long chain derivatives of alkane and alc., phenolics, naphthalene, naphthopyran, androsten phenanthrenone, nepetalactones, flavonoids etc. Nepeta adenophyta Hedge is suggested as a natural alternative for mild pain relief. Our findings endorse the folklore use of N. adenophyta in different pain managements which can be attributed to the presence of polyphenolic compounds, naphthalene derivatives, flavanoids and nepetalactones etc. To complete the study, the researchers used cis-13-Docosenamide (cas: 112-84-5) .

The research results were published in《Fuel》 in 2021.Reference of cis-13-Docosenamide The article conveys some information:

Gasoline direct injection (GDI) vehicles are up against the great challenge of particulate emissions, which were mandatorily constrained by the China-6 emission standard Given the worldwide fuel transition from gasoline to gasoline/ethanol blends, it is important to discuss the effects of ethanol and aromatic contents on particulate emissions of GDI vehicles. In this work, 10% volume of ethanol was added into China-6b gasoline replacing C8 (carbon atoms = 8) alkanes (E10), and the specific aromatic compounds in E10 fuels were adjusted under holding total aromatic content. As there was no limit on individual aromatic compounds in the gasoline standard, the effects of aromatic compounds were investigated over the worldwide harmonized light-duty test cycle (WLTC) with engine cold-start and hot-start at room and low temperatures For GDI vehicles, the results showed that ethanol substituting part of C8 alkanes in gasoline increased the particulate number (PN) but decreased particulate mass (PM) emissions. For vehicles using the combined port fuel injection (PFI)/GDI injection systems, the PM and PN emissions climbed. Aromatic compositions significantly impacted the particulate emissions. With the concentrations of heavy aromatics increased, PM and PN emissions of both GDI and combined-injection vehicles were shown to multiply. To complete the study, the researchers used cis-13-Docosenamide (cas: 112-84-5) .

The article was appeared in 《Journal of Applied Microbiology》. They have made some progress in their research.Recommanded Product: cis-13-Docosenamide The article mentions the following:

In this study, antifungal mechanism of Streptomyces ma. FS-4 on fusarium wilt of banana was investigated. Methods and Results : The physiol. strain of banana fusarium pathogen Fusarium oxysporum f. sp. cubense Race 4 (FOC.4) was used as the target fungus, and the antifungal mechanism of the crude extract of Streptomyces ma. FS-4 was investigated. Eighteen different compounds identified by gas chromatog.-mass spectrometry were composed of aldehydes, Me, hydrocarbons, amides, esters and acids. FS-4 significantly inhibited the spore germination of the target fungi, with an EC50 of 22·78 μg ml-1. After treatment with 100 μg ml-1 FS-4 crude extract, the N-acetylglucosamine content in the mycelium increased 1·95-fold. However, the extract had no significant effect on β-1,3-glucanase. At the FS-4 crude extract dose of 100 μg ml-1, the total sugar and protein contents decreased by 28·6 and 29·1% resp., and the fat content was 41·3%. FS-4 significantly inhibited the activity of the mitochondrial complex III of Foc4, which was reduced by 52·45%. Moreover FS-4 reduced the activity of succinate dehydrogenase, a key enzyme in the Krebs cycle, by 60·2%. However, FS-4 had no significant effect on malate dehydrogenase. The membrane potential on the mitochondrial inner membrane was significantly reduced at the test concentration of 100 μg ml-1. ROS gradually accumulated in the Foc4 hypha, and the burst was 3·97 times higher than the control. To complete the study, the researchers used cis-13-Docosenamide (cas: 112-84-5) .

Sayla;El-Shehawi, Ahmed M.;Elseehy, Mona M.;Reza, Abu Md.;Haque, Ariful published 《R. vesicarius L. exerts nephroprotective effect against cisplatin-induced oxidative stress》. 《BMC Complementary Medicine and Therapies》published the findings. The article contains the following contents:

Cisplatin is an outstanding anticancer drug, but its use has been decreased remarkably due to sever nephrotoxicity. R. vesicarius L. is a leafy vegetable that is evident with anti-angeogenic, anti-inflammatory, anti-proliferative, hepatoprotective, and nephroprotective potential. Therefore, this study was designed to inspect its methanol extract (RVE) for possible nephroprotective effect. Primarily, in vitro antioxidant activity of RVE was confirmed based on 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging aptitude. Thereafter, Swiss Albino male mice were treated with cisplatin (2.5 mg/kg) for 5 successive days to induce nephrotoxicity. Recovery from nephrotoxicity was scrutinized by treating the animals with RVE (25, 50, and 100 mg/kg) i.p. (i.p.) for the next 5 consecutive days. After completion of treatment, mice were sacrificed and kidneys were collected. Part of it was homogenized in sodium phosphate buffer for evaluating malondialdehyde (MDA) level, another part was used to evaluate gene (NQO1, p53, and Bcl-2) expression. Moreover, the hydrogen peroxide (H₂O₂) neutralizing capacity of RVE was evaluated in HK-2 cells in vitro. Finally, bioactive phytochems. in RVE were determined using gas chromatog.-mass spectrometry (GC-MS). RVE showed in vitro antioxidant activity in a dose-dependent fashion with 37.39 ± 1.89 μg/mL IC50 value. Treatment with RVE remarkably (p < 0.05) decreased MDA content in kidney tissue. Besides, the expression of NQO, p53, and Bcl-2 genes was significantly (p < 0.05) mitigated in a dose-dependent manner due to the administration of RVE. RVE significantly (p < 0.05) reversed the H2O2 level in HK-2 cells to almost normal. From GC-MS, ten compounds including three known antioxidants “4H-Pyran-4-one, 2, 3-dihydro-3,5-dihydroxy-6-methyl-“, “Hexadecanoic acid”, and “Squalene” were detected. The extract was rich with an alkaloid “13-Docosenamide”. Overall, RVE possesses a protective effect against cisplatin-induced kidney damage. And cis-13-Docosenamide (cas: 112-84-5) was used in the research process.

The research results were published in《Aquaculture》 in 2022.COA of Formula: C22H43NO The article conveys some information:

A feeding trial was conducted to evaluate a new dietary protein Methanotroph (Methylococcus capsulatus, Bath) bacteria meal (BPM) on nutritional profile of Litopenaeus vannamei. The basal diet was formulated to contain 25% fish meal and then 15%, 30% and 45% of fish meal protein were replaced with BPM in three exptl. diets, which were labeled FM, BPM15, BPM30, and BPM45, resp. A total of 480 uniform-sized shrimp were equally distributed to four groups with three replicates and fed exptl. diets four times daily for seven weeks. Results showed that dietary BPM had no significant effect on the growth performance of shrimp (P > 0.05) but significantly reduced the crude lipid content of the whole body in shrimp fed the BPM30 diet compared to the FM diet (P < 0.05). Total cholesterol and triglyceride in the hemolymph fell significantly with the increase BPM substitution (P < 0.05). Expression of fas (fatty acid synthetase) significantly decreased with increasing BPM substitution, but the expression of cpt-1 (carnitine palmitoyltransferase) significantly increased in shrimp fed BPM30 (P < 0.05). Expression of tor (target of rapamycin) significantly decreased in hepatopancreas, while an opposite change was exhibited in the intestine of shrimp fed BPM45 (P < 0.05). Results of metabolomics indicated that dietary BPM affected the TCA cycle, ascorbate and aldarate metabolism, and glutathione metabolism in shrimp. In conclusion, BPM is an alternative to FM as a novel protein source for shrimp feed, but the changes in whole body composition, lipolysis and fatty acid synthesis, and protein synthesis and muscle metabolites of L.vannamei are noted.cis-13-Docosenamide (cas: 112-84-5) were involved in the experimental procedure.

Product Details of 112-84-5In 2022, Dattilo, Sandro;Gugliuzzo, Chiara;Mirabella, Emanuele F.;Puglisi, Concetto;Scamporrino, Andrea A.;Zampino, Daniela C.;Samperi, Filippo published 《Characterization of VOCs and additives in Italian PET bottles and studies on potential functional aldehydes scavengers》. 《European Food Research and Technology》published the findings. The article contains the following contents:

This study focused on characterization of Volatile Organic Compounds (VOCs) as contaminants and non-volatile additives in Italian PET bottles, also suggesting potential functional aldehydes scavengers. Several VOCs, such as acetic aldehyde (AA), butanal, 3-Me butanal, 1,3-dioxolane, pentanal, hexanal, octanal, 5-hepten-2-one, nonanal, and decanal, were identified by Head Space-Gas Chromatog./Mass Spectrometry (HS-GC/MS) in the PET bottles used for the packaging of six Italian brands mineral waters. AA, 1,3-dioxolane, octanal, 5-hepten-2-one, nonanal, and decanal were the most abundant compounds identified. These contaminants were also identified in the PET-bottled mineral waters. Different experiments using bottle-grade PET pellets (Btlg-PET) and PET bottles′ fragments with and without the addition of epoxidized soybean oil (ESBO) or erucamide as lubricant/plasticizer additives, poly(m-xylene adipamide) (MXD6), and/or anthranilamide (2-aminobenzamide) as potential aldehydes scavengers were carried out. Mostly VOCs observed in the PET bottles analyzed were identified in a neat ESBO sample. The presence of the ESBO additive in the PET-bottle fragments was also observed by matrix-assisted laser desorption/ionization time of flight mass spectrometry anal. (MALDI-TOF MS). The ESBO sub-products were not observed in the virgin btlg-PET pellets analyzed by both HS-GC/MS and MALDI-TOF MS. These results suggest that the VOCs come from an ESBO additive probably loaded during the blow-molding processes used for the manufacturing of PET bottles. Further studies established that MXD6 (1%w), an efficient oxygen scavenger, could be also used as AA scavenger even in the presence of the commonly used anthranilamide.cis-13-Docosenamide (cas: 112-84-5) were involved in the experimental procedure.
