Dumbbell-like Au-Fe3O4 nanoparticles are emerging as attractive nanocatalysts in recent years. However, they still suffer from the instability related activity attenuation. Herein, dumbbell-like Au-Fe3O4 nanoparticles encapsulated in N-doped carbon shell (Au-Fe3O4@Carbon) as novel yolk@shell nanocatalysts were synthesized via template assisted method, with which the yolk@shell scaffolds and even the diameter of the hollow space is totally designable. The yolk@shell structured Au-Fe3O4@Carbon was demonstrated to exhibit high stability and enhanced activity towards the reduction of 4-nitrophenol. Moreover, 100% yield was determined for the benzhydrol oxidation reaction taking advantage of the as prepared Au-Fe3O4@Carbon yolk@shell nanocatalysts. Furthermore, the Au-Fe3O4@Carbon nanocatalysts presented herein exhibit superior recyclability, which laid the foundation for its practical application. The mechanism for the enhanced catalytic behavior were clearly addressed. It is anticipated that the elaborate design of this work can lead to the exploration of novel nanocatalysts with superior catalytic performance.

Six disubstituted Schiff base compounds were synthesized (A1-A6) and characterized using infrared spectroscopy (IR), elemental analyses (EA), 1H NMR, 13C NMR and HRMS spectroscopic techniques. Crystal structure of A1 has been determined by single crystal X-ray diffraction. The antifungal activities against three fungi were assessed, and the results showed that compounds of A1 and A2 have good activity for Wheat gibberellic with EC50 value of 15.89 and 16.99 mg/L, respectively. Compounds of A3, A4 and A6 have good bioactivity against Maize rough bacteria (the value of EC50 is 8.23, 7.56 and 7.92 mg/L, respectively). According to the result of molecular docking, compounds of A1 and A2 have the smallest docking energy (-8.33, -9.00 kcal/mol). Besides, for A1 and A2, the analysis of highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) analysis and molecular electrostatic potential map were to further elaborate the reason for the good activity with density functional theory (DFT)-B3LYP/6-31G.

In this study, a combined experimental and theoretical study of the nonlinear optical properties (NLO) of two chalcone derivatives, (E)-3-(2-methoxyphenyl)-1-(2-(phenylsulfonylamine)phenyl)prop-2-en-1-one (MPSP) and (E)-3-(3-nitrophenyl)-1-(2-(phenylsulfonylamine)phenyl)prop-2-en-1-one (NPSP), in DMSO is reported. The single crystal structures of the compounds, which differ only by the type and position of one substituent, were grown using the slow evaporation technique, and the main structural differences are discussed. The two-photon absorption and first-order hyperpolarizability measurements were performed via the Z-scan technique and hyper-Rayleigh scattering experiment in DMSO. The theoretical calculations were performed using the Density Functional Theory (DFT) at the CAM-B3LYP/6-311++G(d,p) level, and the sum-over-states (SOS) approach in both static and dynamic cases. Besides the electron conjugation achieved by the aromatic rings, olefins, and carbonyl groups, both compounds have a nearly flat chalcone backbone, which is believed to contribute to the nonlinear optical properties. MPSP and NPSP have different positions, even though they have roughly the same conformation and form C-HMIDLINE HORIZONTAL ELLIPSISO interactions. For several studied frequencies, the HRS first hyperpolarizability values for MPSP are greater than those for NPSP, indicating that in most cases the NLO properties of MPSP are better. The comparison among the theoretical and experimental HRS first hyperpolarizability results showed a good agreement. In addition, the two-dimensional second order nonlinear optical spectra obtained from the sum-over-states model indicate good second-order NLO responses of the two chalcone derivatives under external fields. Our findings are important not only to show the potential nonlinear optical application of the two new compounds but also to gain an insight into how different chemical compositions might affect the crystal structures and physico-chemical properties.

A novel oxidative esterification of 1-arylprop-2-en-1-ols with toluene derivatives catalyzed by tetrabutylammonium iodide (TBAI) is reported. The optimization of the reaction conditions illustrates that each of experiment parameters including the catalyst, solvent, and oxidant is significant for present oxidative functionalization. This metal-free protocol has a broad substrate scope including the halogen groups for further functionalization and enriches the reactivity profile of allyl alcohol and toluene derivatives. In addition, this protocol represents a new transformation of allyl alcohol involving C-C bond cleavage and C-O bond forming.

MgO has been shown to catalyze an almost quantitative hydrogen transfer from 2-octanol as the hydrogen donor to benzophenone to form benzhydrol, a useful intermediate product in the pharmaceutical industry. The hydrogen transfer from a series of alcohols to the carbonyl group of benzophenone, its ten derivatives, four polycyclic ketones, and 2-naphthyl phenyl ketone was carried out in liquid (LP) or vapor phase (VP). The dependence of reactivity on the structure of the hydrogen donor, reaction temperature, donor-acceptor ratio, amount of catalyst, and the type and position of substituents has been established. For both reaction modes, optimal conditions for selective synthesis of the alcohols were determined and side reactions were investigated. The results indicate that the reactivity of the ketone is suppressed by the presence of a methyl substituent in the ortho position to a much greater extent in LP mode. A scale-up was demonstrated in the liquid phase mode.

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.

WRKY transcription factors participate in the salt stress responses of various plant species, but the underlying functional mechanisms are not well understood, particularly in grape. In this study, the role of VvWRKY13 in the salt stress response was characterized and the underlying physiological and molecular mechanisms were explored. The results show that VvWRKY13 expression was induced by salt stress, and the VvWRKY13 transcript level in the salt stress-sensitive cultivar was significantly higher than that in the resistant cultivars. Overexpression of VvWRKY13 in Arabidopsis significantly inhibited the growth of transgenic plants under salt stress, indicating that VvWRKY13 has a negative effect on the salt stress response. The photosynthetic rate, contents of proline and soluble sugars, activities of superoxide dismutase (SOD) and catalase (CAT), as well as transcriptional levels of proline and soluble sugar metabolic genes, such as P5CS1, SS1, SS2 and G6PDH, as well as SOD and CAT encoding genes CAT1, CAT2, and Cu/Zn-SOD, all decreased under salt stress, whereas hydrogen peroxide and oxygen-free radical contents increased in transgenic Arabidopsis plants compared with those of wild-type plants. VvWRKY13 suppressed upregulation of SnRK2.3, ABF1, ABF2, ABF3, RD29B, RD29A, and RAB18 induced by salt stress, but showed no significant effect on the transcript levels of SnRK2.2, SnRK2.6, or RD22, indicating that VvWRKY13 affects salt stress tolerance via a specific abscisic acid signaling pathway. Key message VvWRKY13, isolated from grapevine, negatively regulate salt stress tolerance by depressing photosynthetic capacity, inhibiting salt-induced accumulation of osmolytes andup-regulation in antioxidant activity as well as expression of related genes. VvWRKY13 may affects salt stress tolerance by specific ABA signalling.

N-Tosylhydrazones have proven to be versatile synthons over the past several decades. However, to our knowledge, the construction of isoxazolines based on N-tosylhydrazones has not been examined. Herein, we report the first demonstrations of [2 + 2 + 1] cycloaddition reactions that allow the facile synthesis of isoxazolines, employing N-tosylhydrazones, tert-butyl nitrite (TBN) and alkenes as reactants. This process represents a new type of cycloaddition reaction with a distinct mechanism that does not involve the participation of nitrile oxides. This approach is both general and practical and exhibits a wide substrate scope, nearly universal functional group compatibility, tolerance of moisture and air, the potential for functionalization of complex bioactive molecules and is readily scaled up. Both control experiments and theoretical calculations indicate that this transformation proceeds via the in situ generation of a nitronate from the coupling of N-tosylhydrazone and TBN, followed by cycloaddition with an alkene and subsequent elimination of a tert-butyloxy group to give the desired isoxazoline.
