This study’s aim was to determine the pesticide residues in 10 different vegetable commodities from the Asir region, Saudi Arabia. We evaluated 211 vegetable samples, collected from supermarkets between March 2018 and September 2018, for a total of 80 different pesticides using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) after extraction with a multi-residue method (the QuEChERS method). The results were assessed according to the maximum residue limit (MRL) provided by European regulations for each pesticide in each commodity. All lettuce, cauliflower, and carrot samples were found to be free from pesticide residues. A total of 145 samples (68.7%) contained detectable pesticide residues at or lower than MRLs, and 44 samples (20.9%) contained detectable pesticide residues above MRLs. MRL values were exceeded most often in chili pepper (14 samples) and cucumber (10 samples). Methomyl, imidacloprid, metalaxyl, and cyproconazole were the most frequently detected pesticides. Based on the results of this study, we recommend that a government-supported program for the monitoring of pesticide residues in vegetables be established to promote consumers’ health and achieve sustainable farming systems.

Inspired by donor-acceptor (D-A) polymers in organic solar cell and the extended conjugation effect, a conceptual design of D–A-type mesoporous carbon nitride with benzene or thiophene as a -spacer is proposed as an efficient photocatalyst for hydrogen evolution. The photocatalyst was successfully synthesized by a one-pot thermopolymerization based on nucleophilic substitution and a Schiff-base chemical reaction. On the molecular level, the insertion of an in-plane benzene as a -spacer by forming covalent bonds C=N (acceptor) and C-N (donor) interrupts the continuity of tri-s-triazine units and maintains the intrinsic – conjugated electronic system. Synchronously, the enlarged electron delocalization and the intramolecular charge transfer induced by polarization provide force-directed migration of electrons, leading to boosted optical absorption capability and enhanced photogenerated carrier separation. With the synergistic effects of the mesoporous structure and excellent optical and electronic properties, a fivefold increase in the H-2 evolution rate compared with that of pristine g-C3N4 was achieved with robust performance. In addition, other simple aromatic heterocyclic compounds (e.g., pyridine, thiophene and furan)-based D–A structures with a higher hydrogen evolution rate (up to sevenfold increase) were also explored to broaden the application for the design of novel photocatalysts.

This study reports an innovative pathway for successfully synthesizing composite panels using various waste input. For this purpose, seven types of powder from waste or widely available filler i.e. Quartz off-cut, sand, waste seashell, dolomite, limestone aggregates, concrete waste and limestone dust were used. The study aims to assess the effectiveness and mechanical properties of the various waste powder in the production of powder-resin composites. The panels were then compared with the novel polymeric glass composite (PGC) in the previous study (Heriyanto et al., 2018). Following the same procedure in PGC, the filler was individually grounded to 64-108 mu m and chemically treated with amino silane coupling agent (CA). The powder filler (untreated or treated) is then mixed with the resin binder with a ratio of 80/20 respectively, followed by hot pressing the mixture at the pressure of 550 bar at 65 degrees C for 1 h. The final composite slab is then further cut for mechanical testing. It was found in the study that when CA was not added, surface roughness of the powder particles affected the flexural strength of the final panel significantly. High surface roughness particles such as in Quartz, sand and seashell adhere effectively with the resin binder which led to higher strength. On the contrary, other factors like smooth particle morphology in glass, dolomite and limestone as well as porous structure in concrete and clump of very fine powder in limestone dust degrade the strength of the final panels. With CA addition, adhesion between resin and powder filler were improved significantly. Flexural strength after the CA treatment was found to be much affected by particle characteristics. Silica-based panels i.e. quartz, sand and glass which consist of high strength and hardness of silica particles perform better compared to that of calcium carbonate-based panels. Compression strength, toughness, stiffness, scratch resistance, density and water absorption were also reported in this study. The properties of all the treated panels are found to be comparable, or if not, much better than natural stones. These new approaches of using waste filler in powder – resin based composites can be a new alternative to produce green materials that deliver economic and environmental benefits.

Study Objective: To investigate whether the rate of increase in the performance of abdominal myomectomy over a laparoscopic approach after the US Food and Drug Administration (FDA) safety communication regarding morcellator use for myomectomy differs among races. Design: Retrospective cohort study. Setting: The American College of Surgeons National Surgical Quality Improvement data. Patients: Patients aged 18 to 55 years who underwent either laparoscopic or abdominal myomectomy, excluding malignant cases, emergency cases, operations performed by nongynecologic specialists, and cases in which myomectomy was performed during cesarean section. Interventions: None. Measurements and Main Results: The odds ratios of abdominal myomectomy over laparoscopic myomectomy before and after the release of the FDA communication were calculated in 3 race categories: white, African American, and other races. In a logistic regression analysis adjusted for possible confounders, including all races, the odds ratio of abdominal myomectomy before and after the FDA communication was 1.30 (95% confidence interval [CI], 1.20-1.41; p <. 001). In a logistic regression analysis with a product term of FDA communication exposure and race as a possible effect modifier, the African American population showed a significantly greater change in the odds of abdominal myomectomy over laparoscopic myomectomy in comparison with the white population (1.22; 95% CI, 1.02-1.47; p =.03). In contrast, other races showed no significant change (.83; 95% CI,.64-1.08; p =.17). Conclusion: After the FDA communication, the odds ratio of abdominal myomectomy was disproportionately increased in the African American population.

An article Preferential catabolism of the (S)-enantiomer of the herbicide napropamide mediated by the enantioselective amidohydrolase SnaH and the dioxygenase Snpd in Sphingobium sp. strain B2 WOS:000496407200001 published article about EFFICIENT GENERATION; AM1-BCC MODEL; PROTEIN; DEGRADATION; ENANTIOMERS in [Huang, Junwei; Chen, Dian; Jiang, Jiandong] Nanjing Agr Univ, Dept Microbiol, Coll Life Sci, Key Lab Microbiol Agr Environm,Minist Agr, Nanjing 210095, Jiangsu, Peoples R China; [Chen, Dian] Shanghai Jiao Tong Univ, Sch Life Sci & Biotechnol, State Key Lab Microbial Metab, Shanghai 200240, Peoples R China in 2020.0, Cited 37.0.

The (R)- and (S)-enantiomers of the chiral herbicide napropamide (NAP) show different biological activities and ecotoxicities. These two enantiomers behave differently in the environment due to enantioselective catabolism by microorganisms. However, the molecular mechanisms underlying this enantioselective catabolism remain largely unknown. In this study, the genes (snaH and snpd) involved in the catabolism of NAP were cloned from Sphingobium sp. B2, which was capable of catabolizing both NAP enantiomers. Compared with (R)-NAP, (S)-NAP was much more rapidly transformed by the amidase SnaH, which initially cleaved the amide bonds of (S)/(R)-NAP to form (S)/(R)-2-(1-naphthalenyloxy)-propanoic acid [(S)/(R)-NP] and diethylamine. The alpha-ketoglutarate-dependent dioxygenase Snpd, showing strict stereoselectivity for (S)-NP, further transformed (S)-NP to 1-naphthol and pyruvate. Molecular docking and site-directed mutagenesis analyses revealed that when the (S)-enantiomers of NAP and NP occupied the active sites, the distance between the ligand molecule and the coordination atom was shorter than that when the (R)-enantiomers occupied the active sites, which facilitated formation of the transition state complex. This study enhances our understanding of the preferential catabolism of the (S)-enantiomer of NAP on the molecular level.

An environmentally friendly, inexpensive, carbocatalyst, graphene oxide (GO) promoted efficient, metal-free transamidation of various carboxamides with aliphatic, cyclic, and aromatic amines is demonstrated. The protocol is equally applicable to phthalimide, urea, and thioamide determining its adaptability. The oxygenated functionalities such as carbonyl (C=O), epoxy (O), carboxyl (COOH) and hydroxyl (OH), present on graphene oxide surface impart acidic properties to the catalyst. The graphene oxide being heterogeneous in nature, work efficiently under solvent-free reaction conditions providing desired products in good to excellent yields. The one-pot synthesis of 2,3-Dihydro-5H-benzo[b]-1,4-thiazepin-4-one moiety by GO catalyzed Aza Michael addition followed by intramolecular transamidation is also described. A plausible reaction mechanistic pathway involving H-bonding is discussed. The graphene oxide can be recycled and reused up to five cycles without much loss in catalytic activity.

According to Article 12 of Regulation (EC) No396/2005, EFSA has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substance fluometuron. To assess the occurrence of fluometuron residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Commission Regulation (EC) No33/2008 as well as the European authorisations reported by Member States (including the supporting residues data). Based on the assessment of the available data, an MRL proposal was derived and a consumer risk assessment was carried out. All information required by the regulatory framework was present and a risk to consumers was not identified. In addition, EFSA identified some data gaps which are not expected to impact on the validity of the MRL derived but which might have an impact on national authorisations.

Production of nanocomposites from macro-scale materials in situ in a melting compounder is highly desirable yet challenging. In this study, we develop a highly efficient approach for the preparation of cellulose nanofiber (CNF)-reinforced high-density polyethylene (HDPE) composite materials from as-received wood pulp fibers, in which nanofibrillation-assisting plasticizers (urea and urea derivatives) and a diblock copolymer dispersant are used. The most effective plasticizer is urea, which plays a crucial role in producing CNF with less fragmentation during the kneading step, owing to the plasticization/nanofibrillation and the reaction with hydroxyl groups of cellulose fibers into a carbamate. The diblock copolymer as a dispersant enables the stabilization of the appropriate dispersion of the produced CNF in nonpolar HDPE. The resulting composites exhibit significantly improved mechanical properties, including a 6.9-fold increase in the Youngs modulus with 10 wt % loading of wood pulp fibers over that of neat HDPE.

Biodegradation of the phenylurea herbicide linuron appears a specialization within a specific Glade of the Variovorax genus. The linuron catabolic ability is likely acquired by horizontal gene transfer but the mechanisms involved are not known. The full-genome sequences of six linuron-degrading Variovorax strains isolated from geographically distant locations were analyzed to acquire insight into the mechanisms of genetic adaptation toward linuron metabolism. Whole-genome sequence analysis confirmed the phylogenetic position of the linuron degraders in a separate Glade within Variovorax and indicated that they unlikely originate from a common ancestral linuron degrader. The linuron degraders differentiated from Variovorax strains that do not degrade linuron by the presence of multiple plasmids of 20-839 kb, including plasmids of unknown plasmid groups. The linuron catabolic gene clusters showed 1) high conservation and synteny and 2) strain-dependent distribution among the different plasmids. Most of them were bordered by IS1071 elements forming composite transposon structures, often in a multimeric array configuration, appointing IS1071 as a key element in the recruitment of linuron catabolic genes in Variovorax. Most of the strains carried at least one (catabolic) broad host range plasmid that might have been a second instrument for catabolic gene acquisition. We conclude that Glade 1 Variovorax strains, despite their different geographical origin, made use of a limited genetic repertoire regarding both catabolic functions and vehicles to acquire linuron biodegradation.
