Katam, Keerthi published the artcileEffect of solids retention time on the performance of alga-activated sludge association in municipal wastewater treatment and biofuel production, Computed Properties of 110-42-9, the main research area is Chlorella Scenedesmus activated sludge municipal wastewater treatment biofuel production.

Abstract: This research studied the effect of solids retention time (SRT) on algal-activated sludge (AAS) association in carbon-nitrogen-phosphorus removal and lipid synthesis from municipal wastewater. Five 500-mL test reactors were operated at different SRTs (2, 4, 6, 8, and 10 days) parallelly, in a draw-and-fill mode with external aeration. The organic carbon (C), nitrogen (N), and phosphorus (P) removal were pos. correlated with SRT. The highest C, N, and P removal rates of 89, 73, and 91% were observed at 10-day SRT. The algal percentage was more than 60% in the mixed biomass at all the SRTs at a steady state. The lipid content ranged from 15 to 30% and declined with an increase in SRT, with 60% saturated and monounsaturated fatty acid at all the SRTs. The cetane number varied from 56 to 64 indicating a good-quality biofuel. The Fourier transform IR spectroscopy transmittance spectrum for 10-day SRT biomass showed the presence of chloroalkane, alcs., phenols, alkane, esters, allene, alkynes, and phosphine. The AAS system can be used as the main treatment unit for treating municipal wastewater in a single reactor with SRT greater than 4 days.

Guo, Weihong published the artcileMajor constituents of cannabis vape oil liquid, vapor and aerosol in California vape oil cartridge samples, Application of Methyl decanoate, the main research area is cannabis vape oil liquid vapor aerosol major constituent GCMS; EVALI (e-cigarette or vaping product use-associated lung injury); GC-MS; aerosol; delta-9 tetrahydrocannabinol; nontarget; toxin; vape oil; vapor.

During the E-cigarette or Vaping product use Associated Lung Injury (EVALI) outbreak of August 2019 to Feb. 2020, the California Department of Public Health, Food and Drug Laboratory Branch received numerous cannabis vape oil cartridge investigation samples from throughout the state. Many of these products were directly linked to patients; others were collected as part of investigations. We determined the major ingredients and additives in twelve unused cannabis vape oil cartridge samples obtained before (n = 2) and during the EVALI outbreak (n = 10) in California from Sept. 2018 to Dec. 2019. We tested for major constituents in vape oil liquid, vape oil vapor, and vape oil aerosol phases. A nontargeted Gas Chromatog. Mass Spectrometry direct injection screening method was developed for vape oils, a headspace heating module used for vape oil vapors and a solid-phase microextraction (SPME) vaping rig for aerosols generated by vaping. We have identified more than 100 terpenes and natural extracts, 19 cannabinoids, and other potential toxic additives such as Vitamin E Acetate, Polyethylene Glycols, and Medium Chain Triglycerides. We determined more terpenes and minor cannabinoids can be produced via vaporizing and aerosolizing the vape oil. Delta9-THC and potential toxic additives were found at lower levels in the vapor and aerosol than in the vape liquid

Oh, Ki-Kwang published the artcileRevealing Potential Bioactive Compounds and Mechanisms of Lithospermum erythrorhizon against COVID-19 via Network Pharmacology Study, Application In Synthesis of 110-42-9, the main research area is bioactive compound Lithospermum anticoronavirus COVID19; COVID-19; Lithospermum erythrorhizon; MAPK signaling pathway; RELA; TNF; VEGFA; eugenol; methyl 4-prenyloxycinnamate; tormentic acid.

Lithospermum erythrorhizon (LE) is known in Korean traditional medicine for its potent therapeutic effect and antiviral activity. Currently, coronavirus (COVID-19) disease is a developing global pandemic that can cause pneumonia. A precise study of the infection and mol. pathway of COVID-19 is therefore obviously important. The compounds of LE were identified from the Natural Product Activity and Species Source (NPASS) database and screened by SwissADME. The targets interacted with the compounds and were selected using the Similarity Ensemble Approach (SEA) and Swiss Target Prediction (STP) methods. PubChem was used to classify targets linked to COVID-19. The protein-protein interaction (PPI) networks and signaling pathways-targets-bioactive compounds (STB) networks were constructed by RPackage. Lastly, we performed the mol. docking test (MDT) to verify the binding affinity between significant complexes through AutoDock 1.5.6. The Natural Product Activity and Species Source (NPASS) revealed a total of 82 compounds from LE, which interacted with 1262 targets (SEA and STP), and 249 overlapping targets were identified. The 19 final overlapping targets from the 249 targets and 356 COVID-19 targets were ultimately selected. A bubble chart exhibited that inhibition of the MAPK signaling pathway could be a key mechanism of LE on COVID-19. The three key targets (RELA, TNF, and VEGFA) directly related to the MAPK signaling pathway, and Me 4-prenyloxycinnamate, tormentic acid, and eugenol were related to each target and had the most stable binding affinity. The three bioactive effects on the three key targets might be synergistic effects to alleviate symptoms of COVID-19 infection. Overall, this study shows that LE can play a role in alleviating COVID-19 symptoms, revealing that the three components (bioactive compounds, targets, and mechanism) are the most significant elements of LE against COVID-19. However, the promising mechanism of LE on COVID-19 is only predicted on the basis of mining data; the efficacy of the chem. compounds and the affinity between compounds and the targets in experiment was ignored, which should be further substantiated through clin. trials.

Le Roy, Sarah published the artcileComparative Investigation of Conventional and Innovative Headspace Extraction Methods to Explore the Volatile Content of Human Milk, Quality Control of 110-42-9, the main research area is human milk innovative headspace extraction dynamic volatile content; dynamic headspace analysis; headspace extraction; human milk; neonate; olfaction; solid phase micro-extraction; volatilome.

The odor of human milk induces search-like movements and oral activation in newborns, which increases their chances of taking advantage of milk intake and benefits. However, the underlying volatile fraction of human milk remains understudied. This study aimed to devise a simple method to extract a wide range of volatile compounds from small-volume human milk samples. Headspace solid phase micro-extraction (HS-SPME) with a Car/PDMS fiber and dynamic headspace extraction (D-HS) with a Tenax or a trilayer sorbent were tested because of their selective affinity for volatiles. Then, innovative variations of these methods were developed to combine their resp. advantages in a one-step extraction: Static headspace with multiple SPME fibers (S-HS-MultiSPME), Dynamic headspace with multiple SPME fibers (D-HS-MultiSPME) and dynamic headspace with multiple SPME fibers and Tenax (D-HS-MultiSPME/Tenax). The extracts were analyzed by gas chromatog. coupled with mass spectrometric and flame ionization detection. The relative performances of these methods were compared based on qual. and semi-quant. analyses of the chromatograms. The D-HS technique showed good sensitivity for most compounds, whereas HS-SPME favored the extraction of acids. The D-HS-MultiSPME/Tenax identified more than 60 compounds from human milk (some for the first time) and evidence of individual singularities. This method that can be applied to volatilome anal. of any biol. fluid should further our understanding of human milk odor.

Guo, Ziwei published the artcileHighly selective conversion of natural oil to alcohols or alkanes over a Pd stabilized CuZnAl catalyst under mild conditions, Recommanded Product: Methyl decanoate, the main research area is conversion natural oil alc alkanes production.

A novel and green catalytic system based on a Pd stabilized CuZnAl catalyst was designed for one-pot conversion of natural oil components to the corresponding alcs. or long-chain linear and branched alkanes with high selectivity and atom economy. When Me decanoate was used as the model compound, a nearly full yield of n-decanol was obtained at 200 °C and 2 MPa H2 within 8 h. 100% Decane was produced when acidic HZSM-5 was introduced under the same reaction conditions, and the selectivity of n-decane and i-decane could be tuned by temperature Cu species were verified as the active sites for lipid conversion, while a small amount of Pd could stabilize the catalyst to avoid Cu leaching. The reaction pathway involved hydrogenation, where Me decanoate can be equivalently converted to methanol and decanol or decane, and no extra CO2 or CO from decarboxylation or decarbonylation was detected. This system increases the sustainability and economy of natural oil conversion to valuable liquid fuel and chems.

Trinklein, Timothy J. published the artcileDetermination of the signal-to-noise ratio enhancement in comprehensive three-dimensional gas chromatography, HPLC of Formula: 110-42-9, the main research area is signal noise ratio enhancement three dimensional gas chromatog.

We investigate the extent to which comprehensive three-dimensional gas chromatog. (GC3) provides a signal enhancement (SE) and a signal-to-noise ratio enhancement (S/NRel) relative to one-dimensional (1D)-GC. Specifically, the SE is defined as the ratio of the tallest 3D peak height from the GC3 separation to the 1D peak height from the unmodulated 1D-GC separation A model is proposed which allows the analyst to predict the theor. attainable SE (SET) based upon the peak width and sampling d. inputs. The model is validated via comparison of the SET to the exptl. measured SE (SEM) obtained using total-transfer GC3 (100% duty cycle for both modulators) with time-of-flight mass spectrometry detection. Two exptl. conditions were studied using the same GC3 column set, differing principally in the modulation period from the 1D to 2D columns: 4 s vs. 8 s. Under the first set of conditions, the average SEM was 97 (±22), in excellent agreement with the SET of 97 (±18). The second set of conditions improved the average SEM to 181 (±27), also in agreement with the average SET of 176 (±26). The average S/NRel following correction for the mass spectrum acquisition frequency was 38.8 (±11.2) and 59.0 (±27.2) for the two sets of conditions. The enhancement in S/N is largely attributed to moving the signal to a higher frequency domain where the impact of “”low frequency”” noise is less detrimental. The findings here provide strong evidence that GC3 separations can provide enhanced detectability relative to 1D-GC and comprehensive two-dimensional gas chromatog. (GCxGC) separations

Choi, Inseob published the artcileNeutral pH nonfat dry milk beverages with turbidity reduced by sodium hexametaphosphate: Physical and sensory properties during storage, Name: Methyl decanoate, the main research area is neutral pH dry milk bevarage sodium hexametaphosphate sensory property.

There has been ascending demand on beverages enriched with dairy proteins. Calcium chelators can improve transparency and stability of beverages with nonfat dry milk (NFDM) resulting from dissociation of casein micelles. In this study, vanilla-flavored model beverages with 5% or 10% weight/weight NFDM were manufactured with or without 0.43% weight/weight sodium hexametaphosphate (SHMP), phys. properties were studied during 70-day storage at 4°C and room temperature (RT), and sensory properties were evaluated during storage at 4°C. SHMP resulted in decreased turbidity, particle diameter, and zeta-potential magnitude. The turbidity was stable at 4°C but increased from 161 to 315 NTU and 333 to 818 NTU, resp., for beverages with 5% and 10% NFDM after 70-day storage at RT. SHMP resulted in insignificant and significant increase in viscosity for 5% and 10% NFDM beverage, resp. The 10% NFDM beverage with SHMP also developed into a gel during storage at RT but remained fluidic at 4°C. Descriptive sensory anal. suggested that SHMP resulted in soapy flavor and salty taste of beverages with decreasing vanilla and milky flavors after 70-day refrigerated storage. Findings from the present study suggest that SHMP may be used to reduce the turbidity of refrigerated beverages based on NFDM.

Ochieng, Brian O. published the artcileDynamics in nutrients, sterols and total flavonoid content during processing of the edible Long-Horned grasshopper (Ruspolia differens Serville) for food, Application In Synthesis of 110-42-9, the main research area is Ruspolia flavonoid campesterol beta sitosterol dynamic nutrient; Food and nutritional security; Nutrients; Post-harvest processing; Ruspolia differens; Sterols; Tettigoniidae; Total flavonoid.

Long-horned grasshopper (Ruspolia differens Serville) is a tasty delicacy in over 20 African countries. This study evaluated the impact of diverse post-harvest thermal treatment (blanching, boiling, toasting, and deep-frying) on the nutrients, total flavonoid content and sterols preservation of R. differens products. Crude protein, ash, and fiber of R. differens was drastically reduced by deep-frying technique. There was increase in Omega-3 (α-linolenic acid), Omega-6 fatty acid (linoleic and arachidonic acids) and sterols [(22Z)-27-Norergosta-5,22-dien-3β-ol, cholesterol, campesterol, cholest-4-ene-3-one and β-sitosterol] and flavonoids (2-3 folds) during blanching compared to other techniques. The iron and zinc content increased significantly in blanched and boiled products of R. differens. Thus, losses of nutrients, total flavonoid content and sterols during processing of R. differens for food can be mitigated by employing blanching technique, which is cheaper and least time-consuming. The implications of these dietary and therapeutic compounds on human nutrition and health are discussed.

Abdalla, Ashraf N. published the artcileProapoptotic activity of Achillea membranacea essential oil and its major constituent 1,8-cineole against A2780 ovarian cancer cells, Synthetic Route of 110-42-9, the main research area is Achillea essential oil cineole heptanal anticancer agent ovarian cancer; 1,8-cineole; Asteraceae; GC-EI-MS; apoptosis; cell cycle; cytotoxicity; essential oil.

Among the hundreds of reported Achillea species, A. membranacea (Labill.) DC. is one of the six that grow in Jordan. Many species of this genus are used in folk medicine to treat a variety of ailments and several biol. and pharmacol. activities have been ascribed to their essential oil (EO). For this study, the EO obtained from a specimen of A. membranacea grown in Jordan was analyzed by GC-MS. Ninety-six compounds were detected, of which oxygenated monoterpenes was the predominant class (47.9%), followed by non-terpene derivatives (27.9%), while sesquiterpenes represented 14.2% of the total composition The most abundant compound in the EO was 1,8-cineole (21.7%). The cytotoxic activity of the EO was evaluated against three cancer cell lines (MCF7, A2780 and HT29), and one normal fibroblast cell line (MRC5) by MTT assay. The EO induced apoptosis and increased the preG1 events in A2780 cells. 1,8-Cineole, the major constituent of the EO, exhibited submicromolar cytotoxicity against A2780 cells, and was 42 times more selective against MRC5 cells. Its cytotoxicity against A2780 cells was comparable with that of doxorubicin, but 1,8-cineole was more selective for MRC5 normal cells. Interestingly, 1,8-cineole enhanced apoptosis in A2780, and caused a remarkable dose-dependent increase in preG1 events. Thus, 1,8-cineole has demonstrated promising cytotoxic and proapoptotic properties.

Mohamed, Marwa Abd El Hameed published the artcileProtective effects of Saraca indica L. leaves extract (family Fabaceae) against gamma irradiation induced injury in the kidney of female albino rats, COA of Formula: C11H22O2, the main research area is Saraca indica Fabaceae leaf extract kidney gamma irradiation; GC-MS; Saraca indica L.; flavonoids; inflammation; irradiation.

This work was designed to estimate the protective effect of Saraca indica L. leaves ethanolic exract against γ-irradiation induced renal damage in rats. Phytochem. examinations of S. indica L. leaves extract resulted in the separation of three flavanone glycosides: Astilibin (1), Neoastilbin (2), and Eriodictyol-7-O-α-L-rhamnopyranoside (3); two flavonols: Quercetin (4) and Quercetin-3-O-α-L-arabinopyranosyl-(1′′′-6′′)-O-β-D-galactopyranoside (5) in addition of Gallic acid (6) and Me gallate (7). Their structures elucidated by chem. evidences and spectroscopic anal. (1 and 2D-NMR, -ESI-MS, UV). Female rats were used and classified into: control, Ext (200 mg/kg body wt/day orally for 7 days), IRR (8Gy), Ext + IRR, and Sily+IRR groups (received silymarin 50 mg/kg b.wt orally as reference drug). Results showed that S. indica L. leaves extract ameliorated the kidney function tests, hs-CRP, IL-1β, ACE, TNF-α, GSH, and MDA as well as, decreased the histopathol. changes of kidney. In conclusion, S. indica L. leaves extract had a renoprotective activity against irradiation induced renal injury due to its flavononid contents.
