Quality Control of Anthrone. The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.

Laccases produced by Leucoagaricus gongylophorus act in lignocellulose degradation and detoxification processes. Therefore, the use of L. gongylophorus laccase (Lac1Lg) was proposed in this work for degradation of anthracene and others polycyclic aromatic hydrocarbons without the use of mediators. Degradation reactions were performed in buffer aqueous solution with 10 ppm of anthracene and other PAHs, Tween-20 in 0.25% v/v and a laccase preparation of 50 U. The optimum condition (pH 6.0 and 30 degrees C) was determined by response surface methodology with an excellent coefficient of determination (R-2) of 0.97 and an adjusted coefficient of determination (R-adj(2)) of 0.93. In addition, the employment of the mediator ABTS decreased the anthracene biodegradation from 44 +/- 1% to 30 +/- 1%. This optimum pH of 6.0 suggests that the reaction occurs by a hydrogen atom transfer mechanism. Additionally, in 24 h Lac1Lg biodegraded 72 +/- 1% anthracene, 40 +/- 3% fluorene and 25 +/- 3% phenanthrene. The yellow laccase from L. gongylophorus biodegraded anthracene and produced anthrone and anthraquinone, which are interesting compounds for industrial applications. Moreover, this enzyme also biodegraded the PAHs phenanthrene and fluorene justifying the study of Lac1Lg for bioremediation of these compounds in the environment.

Media coverage of disasters potentially damages mental health. Moreover, its effects may differ as recipients may have different emotional responses toward media. The present study examined whether social capital, known to be protective against mental problems, influences a recipient’s emotional response toward news media broadcasting of natural disasters via newspapers, television and internet in Japan. Three social capital components, social participation, social support and cognitive social capital, were considered in the present study as each component reportedly had different effect on mental health. This nationwide cross-sectional survey was undertaken in 2015 among 1,200 Japanese citizens aged 15 to 79 years who were selected using the multi-stage sampling procedure. Data were collected via the drop-off pick-up method using a printed structured questionnaire. Negative and positive emotions were classified based on recipients’ responses against news media. Among 1,190 participants who reported emotions toward news media, 30.9% (368) had experienced any natural disasters, 37.4% (445) belonged to at least one formal or informal organization (social participation), 40.2% (478) had high social support, and 68.8% (819) had high cognitive social capital. High social support was associated with both reduced negative emotional response (OR 0.66, 95% Confidence Interval (CI) 0.47-0.93) and increased positive emotional response (OR 1.48, 95% CI 1.04-2.12) in multivariate analyses, while high cognitive social capital was only associated with increased positive emotional response (OR 1.62, 95% CI 1.11-2.37). These results suggest protective effects of social support and cognitive social capital against news media coverage of natural disasters.

Any catalyst should be efficient and stable to be implemented in practice. This requirement is particularly valid for manganese hydrogenation catalysts. While representing a more sustainable alternative to conventional noble metal-based systems, manganese hydrogenation catalysts are prone to degrade under catalytic conditions once operation temperatures are high. Herein, we report a highly efficient Mn(I)-CNP pre-catalyst which gives rise to the excellent productivity (TOF degrees up to 41 000h(-1)) and stability (TON up to 200 000) in hydrogenation catalysis. This system enables near-quantitative hydrogenation of ketones, imines, aldehydes and formate esters at the catalyst loadings as low as 5-200 p.p.m. Our analysis points to the crucial role of the catalyst activation step for the catalytic performance and stability of the system. While conventional activation employing alkoxide bases can ultimately provide catalytically competent species under hydrogen atmosphere, activation of Mn(I) pre-catalyst with hydride donor promoters, e.g. KHBEt3, dramatically improves catalytic performance of the system and eliminates induction times associated with slow catalyst activation. Manganese-based hydrogenation catalysts are sensitive to high temperatures and may degrade under industrially relevant conditions. Here, the authors report a highly efficient manganese pincer pre-catalyst displaying high TOF values (up to 41 000 h(-1)) and stability (TON up to 200 000) at loadings as low as 5-200 ppm.

Nucleophilic aromatic substitution (SNAr) is routinely used to install (19)F(-)and (18)F(-)in aromatic molecules, but is typically limited to electron-deficient arenes due to kinetic barriers associated with C-F bond formation. Here we demonstrate that a polarity-reversed photoredox-catalysed arene deoxyfluorination that operates via cation-radical-accelerated SNAr enables the fluorination of electron-rich arenes with (19)F(-)and (18)F(-)under mild conditions, and thus complements the traditional arene polarity requirements necessary for SNAr-based fluorination. The utility of our radiofluorination strategy is highlighted by short reaction times, compatibility with multiple nucleofuges and high radiofluorination yields, especially that of an important cancer positron emission tomography agent [F-18]5-fluorouracil. Taken together, our fluorination approach enables the development of fluorinated and radiofluorinated compounds that can be difficult to access by classical SNAr strategies, with the potential for use in the synthesis and discovery of positron emission tomography radiopharmaceuticals.

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) disease is a global rapidly spreading virus showing very high rates of complications and mortality. Till now, there is no effective specific treatment for the disease. Aloe is a rich source of isolated phytoconstituents that have an enormous range of biological activities. Since there are no available experimental techniques to examine these compounds for antiviral activity against SARS-CoV-2, we employed an in silico approach involving molecular docking, dynamics simulation, and binding free energy calculation using SARS-CoV-2 essential proteins as main protease and spike protein to identify lead compounds from Aloe that may help in novel drug discovery. Results retrieved from docking and molecular dynamics simulation suggested a number of promising inhibitors from Aloe. Root mean square deviation (RMSD) and root mean square fluctuation (RMSF) calculations indicated that compounds 132, 134, and 159 were the best scoring compounds against main protease, while compounds 115, 120, and 131 were the best scoring ones against spike glycoprotein. Compounds 120 and 131 were able to achieve significant stability and binding free energies during molecular dynamics simulation. In addition, the highest scoring compounds were investigated for their pharmacokinetic properties and drug-likeness. The Aloe compounds are promising active phytoconstituents for drug development for SARS-CoV-2.

A new protocol for ring-closing metathesis/isomerization sequence was developed. The reactions of selected dienes were performed in overheated 2-methyltetrahydrofuran at 120 degrees C and provided a wide range of cyclic vinyl ethers and amides with good yields and selectivities. Computational analysis suggests that the relative yield of products depends on a thermodynamically driven process on the basis of relative stabilities of isomers.

Although synthetic antioxidants (AOs) and photoinitiators (PIs) are known to be used in printing inks, there are little data on residual concentrations in printing paper products. In the present study, twenty-five PIs, ten AOs, and six transformation products were analyzed in two types of printing paper products, magazines and paperboard food packaging materials, both of which are unavoidable everyday products in our life. Nine AOs and six transformation products can be detected in food packaging materials with total concentrations (geometric mean, GM) of 1.16 x 10(4) ng/dm2. Twenty-two PIs were detected in food packaging materials with total concentrations (GM) of 1.76 x 10(4) ng/dm2. These chemicals were also detected in magazines, albeit at low concentrations (GM of AOs: 466 ng/dm(2), GM of PIs: 1.17 x 10(3) ng/dm(2)). Magazine front covers were found to have much higher concentrations of the target compounds than magazine inside pages. Tris(2,4-di-tert-butylphenyl) phosphate (AO168O), 2,6-di-tert-butyl-4-methylphenol (BHT), bisphenol A (BPA), and benzophenone (BP) were among the predominant chemicals in those printing paper products. Preliminary calculations suggest that dermal exposure to AOs (GM: 6.25 ng/day) and PIs (GM: 17.0 ng/day) via contact with printing paper products is a minor exposure pathway compared to food intake/dust ingestion and is exceedingly unlikely to cause adverse health effects.

Background Accurate sentinel lymph node (SLN) staging is essential for both prognosis and treatment in patients with breast cancer. However, the preoperative lymphoscintigraphy may fail to visualize the SLN in some patients. The purpose of this retrospective study was to identify risk factors associated with SLN nonvisualization on lymphoscintigraphy. For this single-center retrospective study, all data of lymphoscintigraphy of SLN procedures from March 2011 to April 2021 were collected and reviewed from the Amsterdam UMC database. Results A total of 1886 SLN procedures were included in this study. The SLN nonvisualization rate was 25.1% on lymphoscintigraphy at 4 h post-injection. The SLN nonvisualization rate decreased to 9.4% after reinjection. Multivariable analysis showed that age >= 70 years (P < 0.001; OR: 2.27; 95% CI: 1.46-3.53), BMI >= 30 kg/m(2) (P = 0.031; OR: 1.48; 95% CI: 1.04-2.12) and nonpalpable tumors (P = 0.004; OR: 1.54; 95% CI: 1.15-2.07) were independent predictors of SLN nonvisualization. Tumor location, brand of radiopharmaceutical, injected dose and volume, experience of preparer and administrator were not associated with SLN nonvisualization. None of the patient, tumor or tracer characteristics were associated with SLN nonvisualization after radiotracer reinjection. Conclusions This study shows that risk factors for SLN nonvisualization in breast cancer patients during preoperative lymphoscintigraphy are age >= 70 years, BMI >= 30 kg/m(2) and nonpalpable tumors. Our results support the notion that SLN lymphoscintigraphy is a very robust technique that does not depend on the experience of the preparer or administrator of the radiotracer.

Sample introduction method was studied to reduce the extra-column effect in reversed-phase HPLC. Slow transport of a sample band (SToSB) in the pre-column space followed by the introduction of the band into the column at a near-optimum flow rate resulted in larger plate counts for a 1.0 mmID, 5 cm long column as much as 1.4-1.6 times for solutes with a retention factor (k) of 0.5-1.8 compared to a conventional elution method. Further reduction of the extra-column effect was possible by orthogonally splitting the sample band (SplSB) by flow switching during its slow transport followed by the introduction of the leading part of the band into the column. In this case, increased plate counts of up to 2-3 times for solutes with k of 0.5-1.8 were observed for a 1.0 mmID, 5 cm column. The sample introduction method, SToSB in the injector and the pre-column tube of a few mu L, was found to reduce the extra-column band variance by 0.4-0.5 mu L-2 for an UHPLC system with the extra-column volume (V-extra) of ca. 4.6 mu L and the system variance (sigma(2)(extra)) of 1.1 mu L-2 at flow rate of 100 mu L/min, while SToSB and subsequent SplSB were found to be more effective, reducing sigma(2)(extra) by about 0.8 mu L-2. With an UHPLC instrument with V(extra )of about 10 mu L and sigma(2)(extra) of ca. 3.6 mu L-2 at flow rate of 300 mu L/min, 1.4-2.1 times as many plate counts were observed with SToSB and SplSB compared to the normal elution method for early-eluting solutes with k=0.25-1.7 for a column, 2.1 mmID, 5 cm long. With this UHPLC instrument, SToSB and/or SplSB resulted in the reduction of sigma(2)(extra) by 1.2-2.2 mu L-2. (C) 2021 Elsevier B.V. All rights reserved.
