Background: Use of Haemophilus influenzae type b conjugate vaccine is effective in reducing the disease burden, but its coverage in China is unclear. The aim of this meta-analysis is to assess the coverage of Hib conjugate vaccines in children in Mainland China. Methods: We systematically searched Pubmed, Web of Science, Medline, CNKI and Wanfang to identify studies assessing the coverage of Hib vaccine in Chinese children. Random-effects models were used to obtain pooled estimates for Hib vaccine coverage and analyzed heterogeneity with meta-regression and subgroup analyses. Results: Thirty-three studies that included 7,227,480 subjects in 12 provinces met our inclusion criteria. The pooled overall coverage of Hib conjugate vaccine was 54.9% [95% confidence interval (CI): 52.9-57.0]. The pooled coverage for the nonlocal population (54.3%; 95% CI: 52.4-56.3) was lower than that for the local residents (62.0%; 95% CI: 58.4-65.6). The region-pooled coverage was higher in the east of China (59.7%; 95% CI: 57.3-62.1) than in the central and west parts of the country (48.5%; 95% CI: 40.6-56.4). Overall, 26.7% (95% CI: 20.1-33.2) had 1 dose only, 14.8% (95% CI: 10.0-19.6%) had 2 doses, 13.5% (95% CI: 9.1-17.8) had 3 doses and 14.3% (95% CI: 9.7-18.9) had 4 doses. Conclusions: We found a low coverage of Hib conjugate vaccine, particularly for the nonlocal children and those living in the central and west parts of China. Including Hib vaccine into the national immunization program is recommended to reduce disparities in vaccination coverage.

Using green chemical method a series of fifteen systematically substituted 3-(9-substituted anthracen-10-yl)-1-(4-phenyl substituted)prop-2-en-1-one derivatives having high nonlinear absorption coefficient have been synthesized. The nonlinear absorption properties of these compounds were studied using nanosecond pulses at 532 nm wavelength. All 15 derivatives are found to show high nonlinear absorption in the range of 35-640 cm/GW. Among these the derivatives with-NO2 as one of the substitution group show higher nonlinear absorption. The origin of high nonlinear absorption with low linear absorption in the compounds has been attributed to two-step two-photon absorption process. We have shown that the energy bands of these compounds are distributed such that for excitation at 532 nm they have strong nonlinear absorption. These properties of the reported compounds make them a potential candidate for biological imaging and other applications which are based on nonlinear absorption. (C) 2020 Elsevier B.V.

The kinetics of intramolecular-contact formation between remote functional groups in peptides with restricted conformational flexibility were examined using designed peptides with variable-length proline bridges. As probes for this motion, free radicals were produced using the center dot OH-induced oxidation at the C-terminal methionine residue of gamma-Glu-(Pro)(n)-Met peptides (n = 0-3). The progress of the radicals’ motion along the proline bridges was monitored as the radicals underwent reactions along the peptides’ backbones. Of particular interest was the reaction between the sulfur atom located in the side chain of the oxidized Met residue and the unprotonated amino group of the glutamic acid moiety. Interactions between them were probed by the radiation-chemical yields (expressed as G values) of the formation of C-centered, alpha-aminoalkyl radicals (alpha N) on the Glu residue. These radicals were monitored directly or via their reaction with p-nitroacetophenone (PNAP) to generate the optically detected PNAP(center dot-) radical anions. The yields of these alpha N radicals were found to be linearly dependent on the number of Pro residues. A constant decrease by 0.09 mu M J(-1) per spacing Pro residue of the radiation-chemical yields of G(alpha N) was observed. Previous reports support the conclusion that the alpha N radicals in these cases would have to result from (S.*.N)(+)-bonded cyclic radical cations that arose as a result from direct contact between the ends of the peptides. Furthermore, by analogy with the rate constants for the formation of intramolecularly (S.*.S)(+)-bonded radical cations in Met-(Pro)-Met peptides (J. Phys. Chem. B 2016, 120, 9732), the rate constants for the formation of intramolecularly (S.*.N)(+)-bonded radical cations are activated to the same extent for all of the gamma-Glu-(Pro)(n)-Met peptides. Thus, the continuous decrease of G(alpha N) with the number of Pro residues (from 0 to 3) suggests that the formation of a contact between the S-atom in the C-terminal Met residue and the N-atom of a deprotonated N-terminal amino group of Glu is controlled in peptides with 0 to 3 Pro residues by the relative diffusion of the S center dot+ and unoxidized N-atom. The overall rate constants of cyclization to form the (S.*.N)-bonded radical cations were estimated to be 3.8 X 10(6) , 1.8 x 10(6) , and 8.1 x 10(5) s(-1) for peptides with n = 0, 1, and 2 Pro residues, respectively. If activation is the same for all of the peptides, then these rate constants are a direct indication for the end-to-end dynamics along the chain.

We have examined enantioselective bioreduction of acetophenone and its substituted derivatives into corresponding S-alcohols catalyzed by Daucus carota and Petroselinum crispum plant cells in water and isooctane. We found that the nature of the substituent has a profound effect on the relative reactivity of substituted acetophenones and enantioselectivity of biocatalytic reduction. Electron-withdrawing substituents -Br and -NO2 enhance the initial rate of reaction and yields of products, while electron donating substituent -OCH3 decreases them. The reduction rates and yields of products in water were noticeably higher in comparison with similar reductions conducted in isooctane. Correlations between the initial reaction rate and the substituent constant (sigma(+)) in the aromatic ring characterizing its nature were established. Comparison of rho constants of bioreduction catalyzed by D. carota and P. crispum shows that the sensitivity of the reduction to the nature of the substituents is more significant in the case of D. carota biocatalyst. Comparison of rho constants for D. carota and P. crispum in water and isooctane indicates that the sensitivity of bioreduction to the nature of the substituent tends to increase from water to isooctane.

N-Alkylanilines have rarely been used in oxyamination reactions, due to the normally necessary pre-functionalization of the N-atom. Also, the formation of aminium radical cations (ARCs) of anilines bearing alkyl substituents is plagued by the ARC’s tendency to instantaneously convert to alpha-amino radicals or iminium ions. We present a readily available reagent combination that addresses both challenges, and thus allows for an oxyamination with N-alkylanilines via ARCs as the crucial reactive intermediates and excellent diastereoselectivity.

Ferredoxin:NADP(+) oxidoreductase from Plasmodium falciparum (PfFNR) catalyzes the NADPH-dependent reduction of ferredoxin (PfFd), which provides redox equivalents for the biosynthesis of isoprenoids and fatty acids in the apicoplast. Like other flavin-dependent electrontransferases, PfFNR is a potential source of free radicals of quinones and other redox cycling compounds. We report here a kinetic study of the reduction of quinones, nitroaromatic compounds and aromatic N-oxides by PfFNR. We show that all these groups of compounds are reduced in a single-electron pathway, their reactivity increasing with the increase in their single-electron reduction midpoint potential (E-7(1)). The reactivity of nitroaromatics is lower than that of quinones and aromatic N-oxides, which is in line with the differences in their electron self-exchange rate constants. Quinone reduction proceeds via a ping-pong mechanism. During the reoxidation of reduced FAD by quinones, the oxidation of FADH(.) to FAD is the possible rate-limiting step. The calculated electron transfer distances in the reaction of PfFNR with various electron acceptors are similar to those of Anabaena FNR, thus demonstrating their similar intrinsic reactivity. Ferredoxin stimulated quinone- and nitro-reductase reactions of PfFNR, evidently providing an additional reduction pathway via reduced PfFd. Based on the available data, PfFNR and possibly PfFd may play a central role in the reductive activation of quinones, nitroaromatics and aromatic N-oxides in P. falciparum, contributing to their antiplasmodial action.

Single-atom catalysts (SACs) have attracted significant attention because they exhibit unique catalytic performance due to their ideal structure. However, maintaining atomically dispersed metal under high temperature, while achieving high catalytic activity remains a formidable challenge. In this work, we stabilize single platinum atoms within sub-nanometer surface cavities in well-defined 12CaO7Al(2)O(3) (C12A7) crystals through theoretical prediction and experimental process. This approach utilizes the interaction of isolated metal anions with the positively charged surface cavities of C12A7, which allows for severe reduction conditions up to 600 degrees C. The resulting catalyst is stable and highly active toward the selective hydrogenation of nitroarenes with a much higher turnover frequency (up to 25772h(-1)) than well-studied Pt-based catalysts. The high activity and selectivity result from the formation of stable trapped single Pt atoms, which leads to heterolytic cleavage of hydrogen molecules in a reaction that involves the nitro group being selectively adsorbed on C12A7 surface. Stabilize the active metal single atoms under harsh conditions is critical for the development of single atom catalysts. Here the authors report a nanoporous crystal, 12CaO7Al(2)O(3), that can firmly stabilize Pt single atoms in its surface cavities for efficient catalytic hydrogenation of nitroarenes.

The confinement of Bronsted acidic 1-methyl-3-(3-sulfopropyl)-1H-imidazol-3-ium hydrosulfate ([PSMIm][HSO4]) into the channel walls of two-dimensional (2D) COFs using a one-pot self-assembly strategy was achieved by incorporating an imine-linked TPB-DMTP-COF (TPB, triphenylbenzene; DMTP, dimethoxyterephthaldehyde) as the host. An appropriate loading of [PSMIm][HSO4] is crucial for the BIL-COF hybrids to maintain proper geometry in the channel and sufficient acidic sites for the sorbitol substrate and sorbitan intermediate to enter and react. The best yield of isosorbide (97%) from sorbitol to date was obtained in the presence of BIL-COF-30 as the catalyst under optimized conditions. Besides, BIL-COF-30 can be recycled for at least five runs without activity loss.

A novel and efficient oxidative esterification for the selective synthesis of alpha-ketoesters and esters has been developed under metal-free conditions. In the protocol, various alpha-ketoesters and esters are available in high yields from commercially available ketones and potassium xanthates. Mechanistic studies have proven that potassium xanthate not only promotes oxidative esterification but also provides an alkoxy moiety for the reaction, which involves the cleavage and reconstruction of C-O bonds.

We report an efficient HCl center dot DMPU assisted one-pot conversion of aldehydes into nitriles. The use of HCl center dot DMPU as both an acidic source as well as a non-nucleophilic base constitutes an environmentally mild alternative for the preparation of nitriles. Our protocol proceeds smoothly without the use of toxic reagents and metal catalysts. Diverse functionalized aromatic, aliphatic and allylic aldehydes incorporating various functional groups were successfully converted to nitriles in excellent to quantitative yields. This protocol is characterized by a broad substrate scope, mild reaction conditions, and high scalability.
