Many experimental studies have demonstrated that titanium dioxide nanoparticles (TiO2 NPs) could induce adverse health effects in vivo and in vitro. But epidemiological evidence and biomarkers related to early health effects are still lacking. This study aimed to explore biomarkers in the urine samples of workers occupationally exposed to a relatively low concentration of TiO2 NPs. A cross-sectional study was conducted in Jinan, China, involving 132 employees of a TiO2 NP manufacturing plant, among which the exposed group and control group were 1 : 1 matched by confounding factors such as gender, age, BMI, smoking and drinking. Untargeted metabolomics was performed in urine samples using high performance liquid chromatography-mass spectrometry (HPLC-MS) technology. The differential metabolites between the TiO2 NP exposed group and the control group were analyzed and then screened for potential biomarkers using bioinformatics methods. Metabolomics found a total of 1760 differentially expressed metabolites in the TiO2 NP exposed group, of which 60 differential metabolites were simultaneously confirmed by one-dimensional and multi-dimensional statistical analysis. Among these 60 differential metabolites, the relative expression of 27 metabolites increased, and the remaining 33 decreased. Pathway enrichment analysis further found that the metabolic pathway of long chain acyl-coa dehydrogenase deficiency (Lcad) was significantly enriched. Ten differential metabolites were selected as potential biomarkers of occupational exposure to TiO2 NPs using machine learning methods, including dibenzyl ether, quassimarin, tryptophan, etc. The receiver operating characteristic curves (ROCs) of these potential biomarkers showed good sensitivity and specificity. These potential biomarkers also had biological basis for occupational exposure to TiO2 NPs. Therefore, urine metabolites represented by dibenzyl ether are considered as good biomarkers of early health effects for occupational exposure to TiO2 NPs.

Lignin valorization is significantly influenced by the degrees of lignin condensation measured by the amount of cleaved beta-O-4 ether linkages and interunit C-C linkages formed during biomass fractionation. To minimize the cleavage of aryl ether and formation of C-C linkages, a p-toluenesulfonic acid (p-TsOH)/choline chloride (ChCl) solvent system with hydrotropic properties was evaluated. The ChC1 was chosen to control the H+ concentration of the p-TsOH/ChCl solvent system. Compared with p-TsOH/H2O, the degradation of beta-O-4 was kept in a similar rate during p-TsOH/ChCl fractionation; however, the formation of C-C linkage was slower. Under 75/25 p-TsOH/ChCl mass ratio at 80 degrees C for 20 min, 76.6 % of miscanthus lignin, with beta-O-4 content of 30.9 %, and 88.9 % of wheat straw lignin, with beta-O-4 content of 33.6 %, can be dissolved. In addition, the low polar and layered structure of hydrotropic p-TsOH/ChCl system has a strong ability to dissolve lignin, which resulted in lignin with larger particle size and lower surface charge. The results also indicated that lignin from p-TsOH/ChCl solvent system has great potential for lignin depolymerization to aromatics for valorization.

I found the field of Environmental Sciences & Ecology very interesting. Saw the article Environmental contaminants in coastal populations: Comparisons with the National Health and Nutrition Examination Survey (NHANES) and resident dolphins published in 2019.0. Safety of Diphenyl oxide, Reprint Addresses Backer, LC (corresponding author), Ctr Dis Control & Prevent, Natl Ctr Environm Hlth, Atlanta, GA 30333 USA.. The CAS is 101-84-8.

Background: People living in coastal communities are at risk for exposure to environmental hazards, including legacy chemicals. We can use databases such as NHANES to assess whether contaminants in coastal communities are present in higher levels than in the United States overall. We can use information from studies of local animal populations to assess which of these contaminants could have been transferred to people from their shared environment. Objective: Our objectives were to examine the POP profiles in human populations in areas where there are published POP profiles in resident dolphins and to compare our results with data from NHANES and the dolphin studies. Methods: We identified three areas where POPs have been analyzed in local resident dolphin populations (total N = 73). We identified human communities in the same areas, and asked 27 eligible adults to read and sign a consent form, complete a questionnaire about demographics and seafood consumption, provide nine 10-mL blood samples, and provide one sample of seafood (N = 33). Blood and seafood were analyzed for a suite of POPs similar to those analyzed in published dolphin population studies. We compared the results from human blood analyses with NHANES and with data from the published reports of dolphin studies. Results: Levels and proportions of specific POPs found in people and animals reflect POPs found in the local environment. Compared with the nationally representative data reported in NHANES, the levels of many POPs found in high levels in dolphins were also higher in the corresponding human communities. Conclusions: Contaminants measured in marine animals, such as dolphins, can be used to identify the types and relative levels of environmental contaminants expected to occur in people sharing the same environment. Likewise, contaminants measured in coastal human populations can provide insight into which contaminants may be found in nearby animal populations. Published by Elsevier B.V.

Optical tissue clearing using dibenzyl ether (DBE) or BABB (1 part benzyl alcohol and 2 parts benzyl benzoate) is easy in application and allows deep-tissue imaging of a wide range of specimens. However, in both substances, optical clearing and storage times of enhanced green fluorescent protein (EGFP)-expressing specimens are limited due to the continuous formation of peroxides and aldehydes, which severely quench fluorescence. Stabilisation of purified DBE or BABB by addition of the antioxidant propyl gallate efficiently preserves fluorescence signals in EGFP-expressing samples for more than a year. This enables longer clearing times and improved tissue transparency with higher fluorescence signal intensity. The here introduced clearing protocol termed stabilised DISCO allows to image spines in a whole mouse brain and to detect faint changes in the activity-dependent expression pattern of tdTomato.

The hierarchical structure of zeolites plays a crucial role in determining their catalytic performance. Here, the effect of the hierarchical architecture and surface topology of pillared MWW zeolites on the catalytic properties of liquid alkylation between mesitylene and benzyl alcohol was investigated. Pillared MWW zeolite catalysts exhibited excellent activity (similar to 100% conversion) due to their elegant pore architecture, which could largely improve the accessibility of bulk molecules toward active sites on the external surface. In addition, molecular simulation showed that lamellar MWW zeolites with a 12-membered ring semicup surface topology could more effectively accommodate and stabilize the large intermediates formed in alkylation reactions compared with MFI zeolites, resulting in outstanding selectivity for 2-benzyl-1,3,5-trimethylbenzene (similar to 100%). The Thiele modulus (phi) and effectiveness factor (eta) verified that the resultant pillared MWW zeolites possessed a high degree of utilization without internal diffusion constraints under the present reaction conditions.

Formula: C12H10O. The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8.

Bio-based aromatic polyketones (PKs) and polyetherketones (PEKs) were synthesized by the electrophilic substitution reaction of alkoxylated divanillic acid (R-DVA) and 2,2′-dimethoxybiphenyl or diphenylether. Alkoxy side-chains were introduced at the hydroxyl groups of DVA prior to polymerization. Polymerizations were carried out in a phosphorus pentoxide (P2O5)/methanesulfonic acid (MsOH) system. DVA-based PKs and PEKs were soluble in common organic solvents including chloroform and dimethylsulfoxide, and their chemical structures were determined by H-1 and C-13 NMR. The weight-average molecular weights (M-w) of the PKs were 2.6-15.0 x 10(3) g/mol, and those of all PEKs were approximately 1.0 x 10(3). The 10% degradation temperatures of the PKs and PEKs were 340-400 degrees C. Dynamic mechanical analysis showed that the PKs and PEKs were amorphous. The PKs with methyl to butyl side-chains exhibited high glass transition temperatures (T-g) in the range 250-297 degrees C, while T-g of PK (octyl side-chain) was 157 degrees C and those of the PEKs were 73-127 degrees C.

I found the field of Chemistry very interesting. Saw the article How protoporphyrinogen IX oxidase inhibitors and transgenesis contribute to elucidate plant tetrapyrrole pathway published in 2019.0.

Several families of herbicides, especially diphenyl ether (DPE) and pyrimidinedione, target the plant tetrapyrrole biosynthesis pathways and in particular one key enzyme, protoporphyrinogen IX oxidase (PPO). When plants are treated with DPE or pyrimidinedione, an accumulation of protoporphyrin IX, the first photosensitizer of this pathway, is observed in cytosol where it becomes very deleterious under light. Indeed these herbicides trigger plant death in two distinct ways: (i) inhibition of chlorophylls and heme syntheses and (ii) a huge accumulation of protoporphyrin IX in cytosol. Recently, a strategy based on plant transgenesis that induces deregulation of the tetrapyrrole pathway by up- or down-regulation of genes encoding enzymes, such as glutamyl-tRNA reductase, porphobilinogen deaminase and PPO, has been developed. Against all expectations, only transgenic crops overexpressing PPO showed resistance to DPE and pyrimidinedione. This herbicide resistance of transgenic crops leads to the hypothesis that the overall consumption of herbicides will be reduced as previously reported for glyphosate-resistant transgenic crops. In this review, after a rapid presentation of plant tetrapyrrole biosynthesis, we show how only PPO enzyme can be the target of DPE and how transgenic crops can be further resistant not only to herbicide but also to abiotic stress such as drought or chilling. Keeping in mind that this approach is mostly prohibited in Europe, we attempt to discuss it to interest the scientific community, from plant physiologists to chemists, who work on the interface of photosensitizer optimization and agriculture.

MWW type zeolites are characterized by the presence of zeolitic layers of 2.5 nm thickness, containing 10-member ring sinusoidal channels inside and supercavities with 12-member ring openings located on their surfaces. Expansion and pillaring of layered zeolites increase the access to active sites and can enable or facilitate catalytic activity towards larger reactant molecules. This goal is explored in this work reporting the pillaring of layered zeolite MCM-56 with MWW topology by tetraethylorthosilicate (TEOS) treatment with the assistance of isopropanol, aimed at obtaining hierarchical micro-mesoporous systems. MCM-56 (Si/Al = 12) was synthesized with hexamethyleneimine as a structure-directing and aniline as a structure-promoting agent. Hierarchical porous systems were obtained using two different pillaring methods: (1) with TEOS only and (2) with TEOS mixed with isopropanol. The MWW framework was preserved during swelling/pillaring in both methods. Pillared zeolites obtained via alcohol-assisted pillaring possessed unique intermediate micro-mesopores with the size of about 2 nm. IR study revealed a decrease in the concentration of accessible acid centers upon pillaring. However, the fraction of acid sites on the external surface, accessible for adsorption of large molecules, increased by up to 90%. Catalytic activity was evaluated in the Friedel-Crafts alkylation of mesitylene with benzyl alcohol. Pillaring resulted in reduction of the acid site concentrations, but the materials retained high catalytic activity. Pillaring in the presence of alcohol produced increased turnover frequency values based on the concentrations of the external acid sites.

In this study, the influence of grapefruit seed extract (GFSE) was studied on citric acid and zinc oxide incorporated cellulose-based hydrogel films. The effect of GFSE (0.25-1.0%, v/v) on hydrogel films was examined for their physico-chemical, mechanical, thermal, antioxidant and antibacterial properties. The swelling ratio, tensile strength and thermal stability of films decreased with increase in GFSE concentrations. On the other hand, elongation (%) and antioxidant activity of films were found to be 34-60% and 25-79%, respectively for increasing amounts of GFSE. FESEM and FETEM clearly showed that two different types of nanoparticles (50-90 nm and 5-10 nm) were present in GFSE incorporated films. The release of polyphenolic compounds and zinc from films was in sustained manner. Furthermore, the fabricated hydrogel films exhibited antibacterial activity against both E. coli and S. aureus. All these results indicate that the prepared nanocomposite hydrogel films could find their potential applications in wound healing.

Palladium nitrsosyl carboxylates Pd-3(NO)(2)(CX3CO2)(4)(ArH)(2) (I: X=Cl, Ar=Ph; II: X=F, Ar=Tol) are found to be effective catalysts for C-H/C-H oxidative homocoupling of arenes bearing electron-donor as well as electron-withdrawing groups (EWG). Trifluoroacetate complex II is found to be more promising due to higher stability under the reaction conditions. Complex II also shows high performance in intramolecular coupling in diarylsulfides, diarylethers and diarylamines giving corresponding dibenzothiophenes, dibenzofurans and carbazoles with yields ranged from moderate to high. The plausible mechanism is studied by DFT computational analysis basing on Pd-3 linear complexes as major active species. It was found that two deprotonation steps proceed in two different ways: for the first deprotonation SEAr is most probable pathway while for the second one concerted metalation-deprotonation (CMD) is preferable. That can explain high tolerance of the system to different substrates: SEAr is favorable in the presence of electron donor group and EWG facilitate CMD. NO group was found to be involved into the CMD pathway and that is the rate-determining step with the highest activation barrier.
