(Objective) The purpose of this paper is to explore the effects of soil matrix potential (SMP) regulation at different growth stages on the physiological characteristics and yield of spring sown Carthamus tinctorius L. (Method) Three SMP thresholds, i.e.,W1(-20 kPa),W2(-30 kPa) and W3(-40 kPa) were set at the elongation period + branching period (A), and elongation period + branching period + flowering period (B), with SMP of -50 kPa at 0.2 m soil depth below the emitter as the CK. At the flowering period, photosynthetic parameters such as the net photosynthetic rate, stomatal conductance, transpiration rate and intercellular CO2 concentration of Carthamus tinctorius L. leaves were measured. At the same time, the physiological indexes such as chlorophyll, soluble protein, malondialdehyde and relative conductivity of Carthamus tinctorius L. leaves were measured. The flower yield of Carthamus tinctorius L. were counted after harvest. (Result) The net photosynthetic rate, stomatal conductance, transpiration rate and total chlorophyll content of W1B and W2B treatments reached the maximum, in which W1B increased by 37.1%, 60.0%, 44.6% and 34.1% respectively compared with CK, and W2B increased by 39.6%, 57.7%, 42.8% and 38.8% respectively compared with CK; The soluble protein content of W1B treatment was the largest, which was 43.8% higher than that of CK. The malondialdehyde content and relative conductivity of W1B and W2B were the lowest. The malondialdehyde content and relative conductivity of W1B were 25.0% and 19.0% lower than CK, and W2B was 20.8% and 18.3% lower than CK, respectively; The flower yields of W1B and W2B were the highest, which were 65.8% and 57.1% higher than CK respectively. (Conclusion) W1B and W2B treatments had the best photosynthetic characteristics, the highest total chlorophyll content, the lowest malondialdehyde content and relative conductivity, and the highest flower yield. Therefore, maintaining the lower limit of soil matrix potential at -20 kPa or -30 kPa at spring sown Carthamus tinctorius L. elongation period, branching period and flowering period has the highest yield potential. In consideration of water conservation, it is recommended to maintain the lower limit of soil matrix potential at -30 kPa. [ABSTRACT FROM AUTHOR]

In the study, a series of polypyrrole (PPy) samples were prepared by a method of template synthesis at different indigo carmine (IC) concentrations while keeping the amount of pyrrole and FeCl as well as the reaction conditions unchanged. Effects of IC concentration (M) on the morphology, conductivity and microwave absorbing behavior of the obtained PPy products were investigated. The results showed that the morphology of PPy transformed from granular flocking to rods and then to spiral rods as M increased from 0.05 to 7.50 mM, and the morphology transformation mechanism of PPy was attributed to the structural transformation of IC micelles caused by the change of M. The conductivity of PPy was also found to be influenced by M. Further investigation indicated that the spiral rod-shaped PPy (S-5) showed obviously superior microwave absorbing behavior compared with that of the granular flocking shaped PPy or that of the rod-shaped PPy, which was attributed to the benefits of its spiral structure and the comparably higher dielectric loss resulted from its lower conductivity.

Natural products are a major source of biological molecules. The 3-methylfuran scaffold is found in a variety of plant secondary metabolite chemical elicitors that confer host-plant resistance against insect pests. Herein, the diversity-oriented synthesis of a natural-product-like library is reported, in which the 3-methylfuran core is fused in an angular attachment to six common natural product scaffolds-coumarin, chalcone, flavone, flavonol, isoflavone and isoquinolinone. The structural diversity of this library is assessed computationally using cheminformatic analysis. Phenotypic high-throughput screening of β-glucuronidase activity uncovers several hits. Further in vivo screening confirms that these hits can induce resistance in rice to nymphs of the brown planthopper Nilaparvata lugens. This work validates the combination of diversity-oriented synthesis and high-throughput screening of β-glucuronidase activity as a strategy for discovering new chemical elicitors.

Background. Chickens serve as an intermediate host for Toxoplasma gondii and Neospora caninum; infection of free-range (FR) chickens with these organisms is a useful indicator of soil and environmental contamination with oocysts. A total of 700 FR chicken serum samples and 300 heart samples were collected from Henan province from March to July 2015. Antibodies to T. gondii were found in 18.86% (132/700) of the chickens by modified agglutination test (cut-off 1 : 25), while 23.14% (162/700) were positive for N. caninum by indirect fluorescent antibody test (cut-off 1 : 25). T. gondii DNA was detected in the myocardium digestion liquids of 4/25 (16%) FR chickens. The PCR results of N. caninum DNA from FR chicken myocardium digestion liquids (n=25) were all negative. Attempts to isolate viable T. gondii were unsuccessful. The results showed that there were antibodies to T. gondii and N. caninum in FR chickens from Henan province. Accordingly, effective control of feces from cats and dogs and improved pets hygiene habits were needed. To the author’s knowledge, this is the first report of the presence of N. caninum antibody in chickens from China. [ABSTRACT FROM AUTHOR]

Timely delivery of first aid supplies is significant to saving lives when an accident happens. Among the promising solutions provided for such scenarios, the application of unmanned vehicles has attracted ever more attention. However, such scenarios are often very complex, while the existing studies have not fully addressed the trajectory optimization problem of multiple unmanned ground vehicles (multi-UGVs) against the scenario. This study focuses on multi-UGVs trajectory optimization in the sight of first aid supply delivery tasks in mass accidents. A two-stage completely decoupling fuzzy multiobjective optimization strategy is designed. On the first stage, with the proposed timescale involved tridimensional tunneled collision-free trajectory (TITTCT) algorithm, collision-free coarse tunnels are build within a tridimensional coordinate system, respectively, for the UGVs as the corresponding configuration space for a further multiobjective optimization. On the second stage, a fuzzy multiobjective transcription method is designed to solve the decoupled optimal control problem (OCP) within the configuration space with the consideration of priority constrains. Following the two-stage design, the computational time is significantly reduced when achieving an optimal solution of the multi-UGV trajectory planning, which is crucial in a first aid task. In addition, other objectives are optimized with the aspiration level reflected. Simulation studies and experiments have been curried out to testify the effectiveness and the improved computational performance of the proposed design.

Background and objective: IBS-D is a common functional bowel disease with complex etiology and without biomarker. The pathological and physiological basis of IBS-D focuses on visceral hypersensitivity. However, its epigenetic mechanism remains elusive. Our study aimed to integrate the relationship between differentially expressed miRNAs, mRNAs and proteins in IBS-D patients in order to reveal epigenetic mechanism of visceral hypersensitivity from transcription and protein levels and provide the molecular basis for discovering biomarkers of IBS-D. Methods: The intestinal biopsies from IBS-D patients and healthy volunteers were obtained for high-throughput sequencing of miRNAs and mRNAs. The differential miRNAs were selected and verified by q-PCR experiment followed by target mRNA prediction. Biological functions were respectively analyzed for target mRNAs, differential mRNAs and the previously identified differential proteins in order to explore the characteristic involved visceral hypersensitivity. At last, interaction analysis of miRNAs, mRNAs and proteins was performed for the epigenetic regulation mechanism from transcription and protein levels. Results: Thirty-three miRNAs were found to be differentially expressed in IBS-D and five of them were further confirmed, including upregulated hsa-miR-641, hsa-miR-1843, hsa-let-7d-3p and downregulated hsa-miR-219a-5p, hsa-miR-19b-1-5p. In addition, 3,812 differential mRNAs were identified. Thirty intersecting molecules were found from the analysis on the target mRNAs of miRNAs and mRNAs. Fourteen intersecting molecules were obtained from the analysis on the target mRNAs and proteins, and thirty-six intersecting molecules were identified from analysis on the proteins and different mRNAs. According to the integrated analysis of miRNA-mRNA-protein, we noticed two new molecules COPS2 regulated by hsa-miR-19b-1-5p and MARCKS regulated by hsa-miR-641. Meanwhile some critical signaling pathways in IBS-D were found such as MAPK, GABAergic synapse, Glutamatergic synapse, and Adherens junction. Conclusion: The expressions of hsa-miR-641, hsa-miR-1843, hsa-let-7d-3p, hsa-miR-219a-5p, and hsa-miR-19b-1-5p in the intestinal tissues of IBS-D patients were significantly different. Moreover, they could regulate a variety of molecules and signaling pathways, which were involved in the multifaceted and multilevel mechanism of visceral hypersensitivity of IBS-D., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Lu, Chai, Qiu, Zhang, Wu, Fu, Wang and Qin.)
