The aim of this study was to utilize a continuous process for the production of orally administered raloxifene hydrochloride (RX-HCl) loaded nanostructured lipid carrier (NLC) formulations for extended drug release using hot-melt extrusion (HME) technol. coupled with probe sonication, and also to evaluate the in vitro characteristics of the prepared NLCs. Preparation of the NLCs using HME technol. involved two main steps, first formation of a pre-emulsion after extrusion and then size reduction of the pre-emulsion using probe sonication to obtain the NLCs. A screw speed of 100 rpm and a barrel temperature of 85°C, were used in the extrusion process. NLCs prepared by HME technol. showed a lower particle size compared to those prepared by the conventional probe sonication method. The prepared NLCs had high entrapment efficiency values (>90%). In vitro drug release was evaluated using dialysis bag diffusion technique and USP apparatus I. Overall, the RX-HCl loaded NLCs had a higher rate of drug release than the pure drug. The release profile for the F4-3 NLC formulations and pure drug at the beginning and end of the stability study were comparable. The particle size of the prepared NLCs remained stable over the storage period and all PDI and zeta potential values were ≤ 0.5 and in the range of -15 to -30 mV, resp., indicating good phys. stability of the formulations. In summary, HME technol. and probe sonication were successfully used to prepare RX-HCl loaded NLC formulations with shorter processing times as compared to the conventional probe sonication method, which makes this technique a uniquely more industry-friendly method. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1Reference of 31566-31-1).

Glyceryl monostearate (cas: 31566-31-1) 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. 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.Reference of 31566-31-1

Abstract: Coffee is one of the most important commodities worldwide. The industrial processing of coffee cherries generates a considerable volume of byproducts such as wastewater, coffee pulp, mucilage, and husk. These byproducts have sugars and nutrients that can be converted into value-added products via microbial action. In this study, for the first time, we evaluated the potential of coffee pulp and coffee wastewater as substrate for alc. fermentation produce a distilled beverage. The must composed by dry or wet coffee pulp and coffee wastewater added of com. sucrose or sugarcane molasses was fermented by S. cerevisiae. After a screening step, a larger fermentation was carried out with the wet pulp added of sucrose due to its higher alc. fermentation efficiency. The distilled beverage contained 38% (volume/volume) ethanol and 0.2 g/L of acetic acid. The contaminants furfural, hydroxymethylfurfural and Et carbamate were below detection level. Among the 48 volatile compounds detected, the majority (21) were Et esters usually associated with floral and sweet aromas. Et decanoate (996.88μg/L) and Et dodecanoate (1088.09μg/L) were the most abundant esters. Coffee spirit presented taste acceptance of 80% and sugarcane spirit, 70%. The tasters indicated an aroma acceptance of 86% for the coffee spirit and 78% for the sugarcane spirit. The results of this work demonstrate the potential for using coffee byproducts to produce a good quality distilled beverage. Considering our results, especially sensorial anal., we can infer that the produced coffee beverage represents a new alternative for adding value to the coffee production chain.

Caloric restriction (CR) is known to extend lifespan and exert a protective effect on organs, and is thus a low-cost and easily implemented approach to the health maintenance. However, there have been no studies that have systematically evaluated the metabolic changes that occur in the main tissues affected by CR. This study aimed to explore the target tissues metabolomic profile in CR mice. Male C57BL/6J mice were randomly allocated to the CR group (n = 7) and control group (n = 7). A non-targeted gas chromatog.-mass spectrometry approach and multivariate anal. were used to identify metabolites in the main tissues (serum, heart, liver, kidney, cortex, hippocampus, lung, muscle, and white adipose) in model of CR. We identified 10 metabolites in the heart that showed differential abundance between the 2 groups, along with 9 in kidney, 6 in liver, 6 in lung, 6 in white adipose, 4 in hippocampus, 4 in serum, 3 in cortex, and 2 in muscle. The most significantly altered metabolites were amino acids (AAs) (glycine, aspartic acid, L-isoleucine, L-proline, L-aspartic acid, L-serine, L-hydroxyproline, L-alanine, L-valine, L-threonine, L-glutamic acid, and L-phenylalanine) and fatty acids (FAs) (palmitic acid, 1-monopalmitin, glycerol monostearate, docosahexaenoic acid, 16-octadecenoic acid, oleic acid, stearic acid, and hexanoic acid). These metabolites were associated with 7 different functional pathways related to the metabolism of AAs, lipids, and energy. Our results provide insight into the specific metabolic changes that are induced by CR and can serve as a reference for physiol. studies on how CR improves health and extends lifespan.

Rigid biobased polycarbonates with good processability based on a spirocyclic diol derived from citric acid was written by Bonjour, Olivier;Liblikas, Ilme;Pehk, Tonis;Khai-Nghi, Truong;Rissanen, Kari;Vares, Lauri;Jannasch, Patric. And the article was included in Green Chemistry in 2020.Synthetic Route of C13H10O3 The following contents are mentioned in the article:

Introducing biobased polymers from renewable sources for use as high-performance thermoplastics with high demands on mech. rigidity, transparency, thermal stability, as well as good processability, is a significant challenge. In the present work we have designed and prepared a rigid biobased bis-spirocylic diol by di-cycloketalization of a bicyclic diketone (cis-bicyclo[3.3.0]octane-3,7-dione, obtained from citric acid) using trimethylolpropane. This spiro-diol monomer has two reactive primary hydroxyl groups and the synthesis from inexpensive biobased starting materials is straightforward and readily upscalable, involving no chromatog. purification In order to explore the usefulness of the new monomer, it was employed in melt polycondensations with diphenylcarbonate at up to 280°C to form rigid fully amorphous polycarbonates (PCs). Mol. weights (MWs) up to Mn = 28 kg mol^-1 were achieved, and thermal and dynamic mech. measurements showed glass transitions up to T_g = 100°C, with no thermal decomposition until T_d ∼350°C. Solvent cast films had excellent mech. flexibility and strength, as well as a high transparency with only slight coloration. Results by dynamic melt rheol. implied that the high-MW PCs had a good processability at 170°C, with a stable shear modulus over time, but started to degrade via chain scission reactions when the temperature approached 200°C. In conclusion, the present work demonstrates the straightforward preparation of the citric acid-based spiro-diol, and indicates that it is an efficient building block for the preparation of rigid biobased PCs and other condensation polymers. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Synthetic Route of C13H10O3).

They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Synthetic Route of C13H10O3

Elucidation of the layered structures of AMO solvent-washed Mg-Al layered double hydroxides using Mg- and Al K-edge XANES and EXAFS: Impacts of washing solvents on structures and catalytic esterification of benzoic acid with 2-ethylhexanol to 2-ethylhexyl benzoate was written by Kuljiraseth, Jirayu;Wangriya, Aunchana;Klysubun, Wantana;Jitkarnka, Sirirat. And the article was included in Radiation Physics and Chemistry in 2020.Recommanded Product: 2-Ethylhexyl benzoate The following contents are mentioned in the article:

Recently, aqueous miscible organic-layered double hydroxides (AMO-LDHs) have been found to possess impressively-enhanced surface area and pore volume Although computer simulations were adopted to understand the interaction between an AMO solvent and an LDH, their layered structures have not yet been clearly depicted. Therefore, in this work, Mg- and Al K-edge X-ray absorption spectroscopy (XAS), in association with characterization techniques such as XRD, BET, TEM, and STA-FTIR, were employed to visualize the layered structures in the at. level of AMO-LDHs synthesized using two AMO solvents; that are, ethanol and acetone. XANES revealed that Mg (II) and Al (III) had octahedral coordination with oxygen atoms, whereas EXAFS revealed that the coordination numbers of Mg-O and Al-O bonds in the ethanol-washed LDH were distinguished from those of acetone- and water-washed LDHs. In addition, the radial distribution around cations of Mg-O-Al bonds in the layers was different from that in the conventional LDH, due to the differences in charge balance between the LDH sheets and AMO solvents. The illustrations of AMO-LDH layered structures were then constructed, in association with the information from the Mol. Dynamic simulation. As a result, the linear combination fitting based on the Mg K-edge XANES results showed that the change in phase composition of AMO-LDHs was attributed to the significantly-enhanced surface area, acid d., and base d., and consequently to the catalytic activity of AMO LDH-derived mixed oxides on the esterification of benzoic acid, a major component in chem. wastes, with 2-ethylhexanol to valuable 2-ethylhexyl benzoate.

Advanced treatment of wet-spun acrylic fiber manufacturing wastewater using three-dimensional electrochemical oxidation was written by Zheng, Tianlong;Wang, Qunhui;Shi, Zhining;Fang, Yue;Shi, Shanshan;Wang, Juan;Wu, Chuanfu. And the article was included in Journal of Environmental Sciences (Beijing, China) in 2016.COA of Formula: C9H16O4 The following contents are mentioned in the article:

A three-dimensional electrochem. oxidation (3D-EC) reactor with introduction of activated carbon (AC) as particle micro-electrodes was applied for the advanced treatment of secondary wastewater effluent of a wet-spun acrylic fiber manufacturing plant. Under the optimized conditions (c.d. of 500 A/m², circulation rate of 5 mL/min, AC dosage of 50 g, and chloride concentration of 1.0 g/L), the average removal efficiencies of COD (COD_cry), NH₃-N, total organic carbon (TOC), and UV absorption at 254 nm (UV₂₅₄) of the 3D-EC reactor were 64.5%, 60.8%, 46.4%, and 64.8%, resp.; while the corresponding effluent concentrations of COD_cry, NH₃-N, TOC, and UV₂₅₄ were 76.6, 20.1, and 42.5 mg/L, and 0.08 Abs/cm, resp. The effluent concentration of COD_cry was less than 100 mg/L, which showed that the treated wastewater satisfied the demand of the integrated wastewater discharge standard (GB 8978-1996). The 3D-EC process remarkably improved the treatment efficiencies with synergistic effects for COD_cry, NH₃-N, TOC, and UV₂₅₄ during the stable stage of 44.5%, 38.8%, 27.2%, and 10.9%, resp., as compared with the sum of the efficiencies of a two-dimensional electrochem. oxidation (2D-EC) reactor and an AC adsorption process, which was ascribed to the numerous micro-electrodes of AC in the 3D-EC reactor. Gas chromatog. mass spectrometry (GC-MS) anal. revealed that electrochem. treatment did not generate more toxic organics, and it was proved that the increase in acute biotoxicity was caused primarily by the production of free chlorine. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9COA of Formula: C9H16O4).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. 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.

We report a robust, 100% atom-efficiency strategy for preparing waste polycarbonate (WPC)-derived epoxy resin. To demonstrate the preparation process, we perform a pyridine-catalyzed model reaction between di-Ph carbonate (DPC) and diglycidyl ether of bisphenol A (DGEBA) in a molar ratio of 1:2. After epoxy-equivalent titration and two-dimensional NMR (2D-NMR) anal., we confirm that the product is bis(1-(4-(2-(4-(oxiran-2-ylmethoxy)phenyl)propan-2-yl)phenoxy)-3-phenoxypropan-2-yl) carbonate (DPC-EP2). Based on the model reaction, three WPC-based epoxy resins (WPC-EPX, X = 2, 3, and 4) were prepared by the reaction of WPC with DGEBA in a molar ratio of 1:2, 1:3, and 1:4 in the presence of pyridine. The WPC-EPX epoxy resins were cured with WPC, phenol novolac (PN), diamino diphenylmethane (DDM), and dicyandiamide (DICY). The mech. and thermal properties of the thermosets were discussed. We also prepared epoxy/carbon fiber composites and investigated the degradation of epoxy thermosets and the recycling of the carbon fiber. When the WPC-EP2 epoxy resin was cured with WPC, it can be successfully degraded to a phenoxy resin and 1,3-dihyexylurea through a catalyst-free aminolysis process. Undamaged carbon fibers have been recycled, according to the SEM-energy-dispersive x-ray spectroscopy (SEM-EDS) and tensile stress-strain data. The transformation of WPC to WPC-EPX, the aminolysis of WPC-EP2/WPC to a phenoxy resin and 1,3-dihexylurea, and the recycling of carbon fiber in the composite have been successfully demonstrated. Therefore, we believe that this work contributes greatly to the field of “sustainable approaches in waste utilization.”.

Toxic effects of fipronil and its metabolites on PC12 cell metabolism was written by Song, Xiao;Wang, Xinlu;Liao, Guangqin;Pan, Yecan;Qian, Yongzhong;Qiu, Jing. And the article was included in Ecotoxicology and Environmental Safety in 2021.Safety of (2R,9Z)-1-(((2-Aminoethoxy)(hydroxy)phosphoryl)oxy)-3-(palmitoyloxy)propan-2-yl oleate The following contents are mentioned in the article:

Fipronil and its metabolites (fipronil sulfone, fipronil sulfide and fipronil desulfinyl) adversely affect the environment and human health. Targeted metabolomics and lipidomics based on ultra-performance liquid chromatog.-tandem mass spectrometry (UHPLC-MS/MS) was used to analyze the alterations of glycerophospholipids and amino acids after exposure to fipronil and its metabolites at dosages of 0.5, 12.5 and 50 μM for 72 h and to evaluate their different toxic effects. Results showed that fipronil sulfone and fipronil desulfinyl are more toxic than their parent compound, with fipronil desulfinyl as the most toxic and fipronil sulfide as the least toxic. Fipronil and its metabolites affected the metabolism of PC18:1/16:0, PI18:0/20:4, arginine, leucine and tyrosine and the ′′phenylalanine, tyrosine and tryptophan biosynthesis′′ pathway, indicating their possible inducing role in cellular macromol. damage, nerve signal transmission disturbance and energy metabolism disruption caused by oxidative stress. Importantly, fipronil sulfone and fipronil desulfinyl more strongly influenced lipid and amino acid metabolism, mainly reflected in the number of changed glycerophospholipids and differential metabolites associated with oxidative stress, including PS18:0/20:4, glutamate, phenylalanine and histidine for fipronil sulfone and PS18:0/20:4, glutamate, phenylalanine, serine and aspartic acid for fipronil desulfinyl. Therefore, the higher toxicity of fipronil desulfinyl and fipronil sulfone may be also related to oxidative stress. This study provides implications for risk assessment and toxic mechanism research on fipronil and its metabolites.

Heracleum persicum Desf. ex Fischer seeds are a rich source of essential oils (EOs) with high antimicrobial and antioxidant effects. In order to determine the phytochemical variability in various Iranian H. persicum populations, seed samples were collected from 10 different climatic locations. The current study indicated that hexyl butyrate (20.9-44.7%), octyl acetate (11.2-20.3%), hexyl-2-methylbutyrate (4.81-8.64%), and octyl 2-methyl butyrate (3.41-8.91%) were the major components of the EOs. The maximum (44.7%) and the minimum (20.9%) content of hexyl butyrate were obtained from Kaleibar and Sari populations, respectively. Moreover, the octyl acetate content ranged from 2% (in Mahdasht) to 20.3% in Torghabeh population. The CA and PCA analysis divided the 10 Iranian H. persicum populations into three major groups. Populations from Khanghah, Kaleibar, Shebeilo, Showt, Mahdasht, and Amin Abbad showed a distinct separation in comparison with the other populations, having high contents of hexyl butyrate (39.8%) and low contents of octyl acetate (13.5%) (Chemotype II). According to correlation analysis, the highest correlation coefficient was among habitat elevation and hexyl butyrate content. In addition, the mean annual precipitation was negatively correlated with the content of hexyl butyrate. Although octyl acetate content showed high correlation with soil EC and mean annual temperature, it was not statistically significant. In general, in order to have plants with a high content of hexyl butyrate, it is recommended to harvest these plants from regions with high altitude and low rainfall such as Kaleibar.

This study aimed to improve venlafaxine HCl brain delivery using solid lipid nanoparticles (SLNs) made by an ultrasonication method. The impact of the ratio of two surfactants (Tween:Span) on nanoparticle behaviors and their efficiency was examined to achieve optimal brain delivery for venlafaxine. To study the solid-state of venlafaxine in SLNs and detect any potential interactions between the drug and other formulation excipients, PCS, TEM, ATR-FTIR, and DSC were employed. By reducing the HLB (Hydrophilic-lipophilic balance) of the binary surfactants, the particle size of SLN increased. The optimized nanoparticles showed an average particle size of 311.33 ±9.29 nm when the HLB of the ratio of the surfactants (Tween:Span) was adjusted to 8. The zeta potential of SLNs decreased from -15.90 ± 0.70 to -6.95±0.42 mV when the HLB of the system was reduced from 14 to 8. According to the results, the highest entrapment efficiency of 76.05 ±1.42% was observed for the formulation with the largest particle size and the lowest HLB value (HLB 8). DSC anal. showed that venlafaxine was in an amorphous state in SLN. The findings of the ATR-FTIR also excluded any chem. interactions between excipients and the drug. Venlafaxine-SLN had a prolonged release pattern, according to the in vitro diffusion process. Venlafaxine oral absorption from SLN was also substantially higher than venlafaxine solution after single-dose oral administration of venlafaxine preparations This research demonstrated that the venlafaxine-SLN might be employed as a potential nano-vehicle for venlafaxine brain delivery and potentially opens up new avenues for depression treatment.
