摘要：
Salvia miltiorrhiza has numerous compounds with extensive clinical application. “Sweating”, a processing method of Traditional Chinese Medicine (TCM), results in great changes in pharmacology and pharmacodynamics. Previously, chromatogram of 10 characteristic metabolites in S. miltiorrhiza showed a significant difference after “Sweating”. Due to the complexity of TCM, changes in metabolites should be investigated metabolome-wide after “Sweating”. An untargeted UPLC/MS-based metabolomics was performed to discover metabolites profile variation of S. miltiorrhiza after “Sweating”. Multivariate analysis was conducted to screen differential metabolites. Analysis indicated distinct differences between sweated and non-sweated samples. 10,108 substance peaks had been detected altogether, and 4759 metabolites had been identified from negative and positive ion model. 287 differential metabolites were screened including 112 up-regulated and 175 down-regulated and they belong to lipids and lipid-like molecules, and phenylpropanoid and polyketides. KEGG analysis showed the pathway of linoleic acid metabolism, and glyoxylate and dicarboxylate metabolism were mainly enriched. 31 and 49 identified metabolites were exclusively detected in SSM and NSSM, respectively, which mainly belong to carboxylic acids and derivatives, polyketides and fatty acyls. By mapping tanshinones and salvianolic acids to 4759 identified metabolites library, 23 characteristic metabolites had been identified, among which 11 metabolites changed most. We conclude that “Sweating’’ has significant effect on metabolites content and composition of S. miltiorrhiza. © 2020, The Author(s).

摘要：
The venom of Lycosoidea spiders is a complex multicomponent mixture of neurotoxic peptides (main components) and antimicrobial peptides (AMPs) as minor components. In this study, we described the high-throughput identification and analysis of AMPs from Lycosa sinensis venom (named LS-AMPs) using a combination strategy that includes the following three different analysis approaches: (i) peptidomic analysis, namely reversed-phase high-performance liquid chromatography (RP-HPLC) separation plus top-down sequencing by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MS); (ii) transcriptomic analysis, namely cDNA library construction plus DNA sequencing; (iii) bioinformatic analysis, namely analysis and prediction for molecular characters of LS-AMPs by the online biology databases. In total, 52 sequences of AMPs were identified from L. sinensis venom, and all AMPs can be categorized into eight different families according to phylogenetic analysis and sequence identity. This is the largest number of AMPs identified from a spider species so far. In the present study, we demonstrated molecular characteristics, such as complex precursor, N- and/or C-terminally truncated analogs, and C-terminal amidation of LS-AMPs from L. sinensis venom. This is a preliminary investigation on the molecular diversification of venom-derived AMPs from the wolf spider species (family Lycosidae), and a detailed investigation on the functional diversity of LS-AMPs will be preformed in the future.

摘要：
Camellia oleifera shell-based activated carbon (COSAC) was prepared by H3PO4 activation method and further used to remove U(VI) from the aqueous solution in a batch system. This research examined the influence of various factors affecting U(VI) removal, including contact time, pH, initial U(VI) concentration, and temperature. The results showed that the U(VI) adsorption capacity and removal efficiency reached 71.28 mg/g and 89.1% at the initial U(VI) concentration of 160 mg/L, temperature of 298 K, pH 5.5, contact time of 60 min, and COSAC dosage of 2.0 g/L. The pseudo-first-order, pseudo-second-order, and intraparticle diffusion equations were used to identify the optimum model that can describe the U(VI) adsorption kinetics. The pseudo-second-order kinetics model performed better in characterizing the adsorption system compared with the pseudo-first-order and intraparticle diffusion models. Isotherm data were also discussed with regard to the appropriacy of Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich models. The Langmuir model described the U(VI) adsorption process the best with a maximum adsorption capacity of 78.93 mg/g. Thermodynamic analysis (Delta G(0) < 0, Delta H-0 > 0, and Delta S-0 > 0) indicated that the U(VI) adsorption process is endothermic and spontaneous. All the results imply that COSAC has a promising application in the removal or recovery of U(VI) from aqueous solutions.

摘要：
Main findings: The Sb resistant bacterium impacted the fraction and quantity of IP on rice roots, and it decreased the Sb concentrations in rice shoots. © 2019 Elsevier LtdIron plaque (IP) is crucial in mitigating antimony (Sb) uptake and accumulation in rice plants, while, few studies focused on the effect of the iron plaque-associated Sb resistant bacteria on IP and Sb uptake into rice plants. Here, the effect of a Sb resistant bacterium (GenBank accession No. MH345840, with potential of conversion soluble Sb(III) into insoluble Sb2O3) on IP and Sb(III)/Sb(V) uptake under hydroponic condition was investigated. The results showed that in the presence of Sb(III), a large quantity of bacterial cells consorted with IP on rice roots, the bacterial inoculum altered the IP fraction distribution without enhancing its amount. However, it reduced Sb(III) uptake into rice roots. On contrary, seldom bacterial cells associated with the IP on rice roots in the presence of the Sb(V), the bacterial inoculum increased the IP amount slightly, and did not decline the Sb(V) uptake into rice roots. It also showed that the bacterial inoculum decreased Sb concentrations in rice shoots greatly in both Sb(III) and Sb(V) supplied treatments. © 2019 Elsevier Ltd

Aceraceae;Acer;Dipteronia;Leaf architecture;Systematic significance
摘要：
Leaf architecture of 30 species representing 2 genera of Aceraceae in China was investigated for the first time. Within the 30 species, 10 species are found with an actinodromous venation pattern, while 20 species are found with a pinnate venation pattern. Within the 20 species with pinnate venation, 10 species are camptodromous, while the other 10 species are craspedodromous. Four types of leaf teeth are detected, viz. entire, toothed, lobed and partite. The secondary veins of most species are unbranched, except for Acer cordatum. Most species have obvious intersecondary veins, except for 4 species, i.e., Dipteronia sinensis, D. dyerana, Acer davidii and A. maximowiczii. All species have both reticulate and percurrent tertiary veins, except for A. pentaphyllum, which has only reticulate tertiary veins. All species are found with irregular areoles, except for A. pentaphyllum which is found to be regular. Veinlets are simple, branched or absent. A key to the genera and sections ofAceraceae mainly based on leaf architecture characters is presented.

Floral development;Globbeae;heterochrony;labellum;Staminode;Zingiberaceae
摘要：
We observed the floral development of Hemiorchis burmanica and two species of Gagnepainia, which make up the sister group of Globba in Globbeae, as well as a selected number of species of Globba. Our observations revealed that in Gagnepainia, a “fifth staminode,” develops as part of the labellum, while it is generally lost in other Zingiberaceae. The fifth staminode, however, was not initiated in the labellum of Hemiorchis. A fifth staminode was also observed in Globba geoffrayi but was not found in all other species of Globba investigated. While the staminode becomes an integral part of the labellum in Gagnepainia, it remains small and almost aborts at later stages of development in G. geoffrayi. These results indicate that the development of a fifth staminode could be a recurring plesiomorphic trait for Globbeae, only retained in G. geoffrayi. The retention of the fifth staminode and its heterochronic shift may be linked with the mechanical constriction within the flower bud. The results may also support the interpretation of an atavistic expression of a once lost staminode. © Copyright © 2020 Iwamoto, Ishigooka, Cao and Ronse De Craene.

摘要：
The active sites of a mixed Cu/Ce material and the doping effect of typical element (iron, Fe) on the active species and the catalytic behavior of Cu/Ce for CO preferential oxidation in rich H 2 (CO-PROX) were investigated by in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), in situ oxygen storage capacity measurement (OSC) combined with designed temperature-programmed reduction (TPR), along with Raman, X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and temperature-programmed desorption/reduction of CO (CO-TPD/TPR). These results showed that two kinds of surface active center were involved in the CuCe- and Fe-doped CuCe systems, that is, Cu + as adsorption sites for the chemisorption and the activation of CO molecules, the surface reactive oxygen (the highly dispersed oxygen and surface lattice oxygen) that directly participated in the whole CO oxidation process. The addition of Fe into CuCe sample resulted in the incorporation of Fe into CeO 2 lattice forming Fe-O-Ce structure and generated more oxygen vacancies, which not only enhanced the interaction between Cu and Ce to form more Cu + absorption sites but also trapped the gas-phase oxygen and promoted the release of subsurface lattice oxygen to supply more reactive oxygen. Thus, the turnover frequency (TOF) value was increased from 3.62 × 10 -2 s -1 for CuCe to 4.50 × 10 -2 s -1 for Fe-doped CuCe. Moreover, with the enhancement of the lattice oxygen migration combined with the promotional role of Fe on the water gas shift (WGS), the capacity of the resistance to CO 2 and H 2 O was enhanced for Fe-doping CuCe, and the corresponding stability time was largely prolonged from 170 to 400 h, in the coexistence of CO 2 and H 2 O. © 2019 American Chemical Society.

摘要：
Spider venoms are insecticidal mixtures with diverse biological activities, and acylpolyamines are their small molecular active components. However, the mechanism for the insecticidal activity of acylpolyamines remains to be elucidated. Here, the structure and function of two acylpolyamine toxins, AVTX-622 and AVTX-636, from Araneus ventricosus were investigated. Nuclear magnetic resonance (NMR) analysis illustrated that the structure of two toxins was very similar, and compared to AVTX-636, AVTX-622 only missed a methylene group in the linker region between the polyamine head and tail. Both the two toxins did not inhibit on voltage-gated sodium channels in mammalian neuronal cells. Intriguingly, AVTX-622, but not AVTX-636, inhibited voltage-gated sodium channels in DUM neuronal cells of Periplaneta americana. Further animal test displayed that the paralyzing potency of AVTX-622 on insect was over ten-times stronger than that of AVTX-636. These findings indicate that a single methylene deletion from AVTX-636 offered AVTX-622 the insect-selective voltage-gated sodium channel activity, which not only elucidated structure-function of the toxins, but also provided new clues for insect-selective insecticide design. © 2019 American Chemical Society.
