Objective: To explore the relationship between meteorological factors and scarlet fever incidence from 2006 to 2017 in Guangzhou, the largest subtropical city of Southern China, and assist public health prevention and control measures. Methods: Data for weekly scarlet fever incidence and meteorological variables from 2006 to 2017 in Guangzhou were collected from the National Notifiable Disease Report System (NNDRS) and the Guangzhou Meteorological Bureau (GZMB). Distributed lag nonlinear models (DLNMs) were conducted to estimate the effect of meteorological factors on weekly scarlet fever incidence in Guangzhou. Results: We observed nonlinear effects of temperature, relative humidity, and wind velocity. The risk was the highest when the weekly mean temperature was 31 degrees C during lag week 14, yielding a relative risk (RR) of 1.48 (95% CI: 1.01-2.17). When relative humidity was 43.5% during lag week 0, the RR was 1.49 (95% CI: 1.04-2.12); the highest RR (1.55, 95% CI: 1.20-1.99) was reached when relative humidity was 93.5% during lag week 20. When wind velocity was 4.4 m/s during lag week 13, the RR was highest at 3.41 (95% CI: 1.57-7.44). Positive correlations were observed among weekly temperature ranges and atmospheric pressure with scarlet fever incidence, while a negative correlation was detected with aggregate rainfall. The cumulative extreme effect of meteorological variables on scarlet fever incidence was statistically significant, except for the high effect of wind velocity. Conclusion: Weekly mean temperature, relative humidity, and wind velocity had double-trough effects on scarlet fever incidence; high weekly temperature range, high atmospheric pressure, and low aggregate rain fall were risk factors for scarlet fever morbidity. Our findings provided preliminary, but fundamental, information that may be useful for a better understanding of epidemic trends of scarlet fever and for developing an early warning system. Laboratory surveillance for scarlet fever should be strengthened in the future. (C) 2019 Elsevier B.V. All rights reserved.

An article Origin and turnaround of enantioselectivity in a chiral organocatalysed Diels-Alder reaction: A mechanistic study WOS:000526142100001 published article about ASYMMETRIC CYCLOADDITION; ELECTRONIC-STRUCTURE; ANTHRONE; STEREOSELECTIVITY; MALEIMIDES; SOLVENT; BOND in [Maliekal, Parimal J.; Gulvi, Nitin R.; Karnik, Anil V.; Badani, Purav M.] Univ Mumbai, Dept Chem, Mumbai 400098, Maharashtra, India in 2020, Cited 51.

The present work comprises exploring the efficacies of the chiral organocatalysts employed in the classic Diels-Alder reaction between anthrone and maleimide in generating an enantioselective product. The complete mechanism of the reaction has been figured out by performing the electronic structure calculations at the density functional theory (DFT) level. Our calculations suggest that the reaction commences with the abstraction of acidic proton of anthrone instigated by organocatalysts, (S)-(-)-N-(methyl-2 ‘-pyridyl)-2-(alpha-hydroxyethyl)benzimidazole [Pyr-HEB] and (S)-(-)-N-(methyl-1 ‘-benzotriazolyl)-2-(alpha-hydroxyethyl)benzimidazole [Btz-HEB]. Subsequently, N-methyl maleimide interacts with the nucleophilic carbon of anthrone in a stepwise pathway, either from left-hand side or right-hand side, resulting in the generation of an enantioselective chiral product. A unique feature in the above reaction was that Pyr-HEB and Btz-HEB favoured the formation of SS-product and RR-product, respectively, with high enantioselectivity. The turnaround of enantioselectivity upon changing the catalyst has been attributed to the noncovalent interaction and steric orientation in the molecule during the intermediate reaction steps. An estimated value of degree of enantioselectivity, for both the catalysts, was obtained in accordance with the experimental findings.

A sp(3) C-H bond functionalization and C – C bond cleavage were realized by AIBN/0 2 catalyst system, providing a series of benzophenones under mild reaction conditions. The mechanistic study shows that a peroxide intermediate is involved in this transformation, and in the case of diphenylmethanes, the sp(3) C-C bond is cleaved through the peroxide rearrangement, which might provides a new way to cleave relatively strong C-C bond and be applied to more general C-C bond activation.

An efficient and green protocol for aerobic oxidation of benzylic alcohols in ethanol using Cu-I-Y zeolite catalysts assisted by TEMPO (TEMPO = 2,2,6,6-tetramethyl-1-piperidine-N-oxyl) as the radical co-catalyst in the presence of atmospheric air under mild conditions is reported. The Cu-I-Y zeolite prepared via ion exchange between CuCl and HY zeolite was fully characterized by a variety of spectroscopic techniques including XRD, XPS, SEM, EDX and HRTEM. The incorporation of Cu(i) into the 3D-framework of the zeolite rendered the catalyst with good durability. The results of repetitive runs revealed that in the first three runs, there was hardly a decline in activity and a more substantial decrease in yield was observed afterwards, while the selectivity remained almost unchanged. The loss in activity was attributed to both the formation of CuO and the bleaching of copper into the liquid phase during the catalysis, of which the formation of CuO was believed to be the major contributor since the bleaching loss for each run was negligible (<2%). In this catalytic system, except TEMPO, no other additives were needed, either a base or a ligand, which was essential in some reported catalytic systems for the oxidation of alcohols. The aerobic oxidation proceeded under mild conditions (60 degrees C, and 18 hours) to quantitatively and selectively convert a wide range of benzylic alcohols to corresponding aldehydes, which shows great potential in developing green and environmentally benign catalysts for aerobic oxidation of alcohols. The system demonstrated excellent tolerance against electron-withdrawing groups on the phenyl ring of the alcohols and showed sensitivity to steric hindrance of the substrates, which is due to the confinement of the pores of the zeolite in which the oxidation occurred. Based on the mechanism reported in the literature for homogenous oxidation, a mechanism was analogously proposed for the aerobic oxidation of benzylic alcohols catalysed by this Cu(i)-containing zeolite catalyst.

12-Deoxyphorbol-13-phenylacetate (DPP), found in Euphorbia resinifera, is a prototype of a new class of phorbol derivatives that function as protein kinase C activators with potent anti-tumor-promoting activity. To better understand the biosynthesis of DPP in E. resinifera and develop methods for its production, we used next-generation sequencing technologies to build a transcriptome dataset. We obtained a total of approximately 27,102,078 clean reads that were assembled into 90,448 unigenes. Of those, 129 and 59 unigenes were identified in the Terpenoid Backbone Biosynthesis (TBB) (KEGG map00900) and the Diterpenoid Biosynthesis (DB) (KEGG map00904) pathways, respectively. We investigated the expression patterns of 23 DPP biosynthesis-related genes and validated the results by quantitative real time PCR. The results showed that CMK (4-diphosphocytidyl-2-C-methyl-o-erythritol kinase), MECS (2-C-methyl-D-erythritol 2,4-cyclodiphosphate synthase), HDS (1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate synthase), and IPI (Isopentenyl-diphosphate Delta-isomerase) of the methylerythritol 4-phosphate (MEP) pathway had a higher expression compared to other genes of TBB, whereas the expression levels of genes involved in the mevalonic acid (MVA) pathway were relatively lower and not significantly different from each other. Furthermore, the expression of the 23 genes in root, stem and young stem differed, and the statistical results indicated that HMGS (Hydroxymethylglutaryl-CoA synthase), MVK (mevalonic acid), MECT (2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase), MECS, HDS and IPI in the TBB pathway as well as KS in the DB pathway were significantly and positively correlated with the CS (casbene synthase) gene. These results suggested that both cytosol-localized MVA and plastid-localized MEP pathways may have a significant contribution in DPP accumulation, with MEP pathway playing a dominant role. To the best of our knowledge, this study is the first transcriptome analysis of E. resinifera and the results reported here will aid the identification of functional genes and better understanding of DPP biosynthesis.

The ring-expanded strategy in nonfullerene acceptors (NFAs) with the acceptor-donor-acceptor backbone has been reported to be an effective method to improve the fill factor (FF), open circuit voltage (VOC), and short circuit current (JSC) simultaneously in organic photovoltaics. However, design control is still missing in the ring-expanded strategy, and is urgently needed to further develop the origins and rules. To give insight into this strategy, a detailed theoretical study of the ring-expanded mechanism is performed on the systems comprising different 9,9 ‘-bifluorenylidene-based cores and 1,1-dicyanomethylene-3-indanone group. Some main parameters involved in photoelectric conversion mechanism under the donor excitation (DE) and/or acceptor excitation (AE) are assessed by changing the position and size of ring-expanded modes. The results show that the external ring-expanded modes can not only maintain the original advantage as much as possible, variations in sizes and positions also offer them an opportunity to regulate the aforementioned parameters systematically, leading to better improvement regardless of AE or DE. Thus, the steady improvement in performance mentioned previously is the key to overcoming the negative correlation among FF, VOC, and JSC. This insight and discovery of the ring-expanded strategy provides new design approaches for the next generation of NFAs.
