The fall armyworm(FAW,Lepidoptera:Noctuidae),Spodoptera frugiperda(J.E.Smith),invaded China in mid-December 2018;since then,it has become a great threat to Chinese agricultural production.Qinling Mountains-Huaihe River region(QM-HRR)is the transitional zone between northern and southern China,an important region for both corn and wheat production.Based on the actual occurrence of QM-HRR invaded by FAW in 2019,daily mean surface air temperature and nocturnal wind conditions at 925 hPa were examined,and migratory routes of FAW moths originated in QM-HRR were modeled by a forward-trajectory-analysis approach.The results indicated that migratory activities of FAW adults emerged in QM-HRR were initiated from late June.The moths from western QM-HRR,where has complex topographic terrain,mainly flied to Ningxia and Inner Mongolia before mid September.However,FAW moths from the eastern QM-HRR primarily engaged in high-altitude northward transport assisted by the prevailing southerly winds before mid August,and the North China Plain was identified as the main destination of FAW.Meanwhile,the migration trajectories of FAW moths had a possibility to reach the Northeast China Plain.From mid August,FAW moths in eastern QM-HRR largely migrated southward and returned to the Yangtze River Valley.This study provides detailed information on the occurrence and migration routes of FAW moths from QM-HRR and will be helpful for early warning and development of integrated pest management strategies for the control of this exotic insect pest.

The fall armyworm(FAW),Spodoptera frugiperda is one of the most damaging crop pests,and it has become major threat to the food security of many countries.In order to monitor possible invasion of this pest into China,a searchlight trap was established in March 2018 in western yunnan Province,China,where it has served as the"first station"for many pests that have migrated from Myanmar to China.A number of suspected FAW moths were captured and identified by DNA sequencing.The results showed that the FAW moth was first captured on December 11 and formed its first immigration peak in mid-December 2018.DNA detection revealed that the early invading FAW population was the"corn-strain".The field survey indicated that the pest mainly colonized corn in Pu’er,Dehong and Baoshan areas.Migration trajectory simulation implied that the moths might have mainly come from the eastern area in the mid-latitude region of Myanmar(20-25°N,94-100°E).This case study confirmed the first immigration of FAW into China,and will be helpful for guiding monitoring and management work to control this pest.

Vertical-looking radar （VLR） has allowed long-term automatic monitoring of the altitudinal and temporal dynamics of high- flying insect populations. To investigate whether ground beetle, insect of Coleoptera, was capable of migrating and its migration pattern by taking advantages of capability of the VLR for long-term real-time automatic monitoring, the migration of Coleoptera ground beetle was investigated by setting up radar observation points, making long-term observation using the VLR and related supplementary equipment, and analyzing low altitude air current and large area circulating current in combination with the meteorological data. Information obtained in 2005 and 2006 showed that the seasonal activities of ground beetles traps of trap lamps were mainly from late June to late August, peak period was mainly in August, seasonal traps of high-altitude lamps and ground lamps were featured by sudden increase and sudden decrease; in peak period, the height of radar echo point could be as high as 600 m, while it was mainly below the height of 450 m; night activities mainly occurred from 20：00 to 22：00, in very few nights, radar echo could last until about 04：00, changes in numbers of ground beetles within the searchlights were consistent with radar echo intensity; ground beetle images were successfully trapped in the sweep nets carried by captive balloons at the height of 200 m. Some species of Carabidaes had some degrees of migration, thus providing the foundation for investigating the migration of Coleoptera insects.

Diet,serving as a vital source of nutrients,exerts a profound influence on human health and disease progression.Recently,dietary interventions have emerged as promising adjunctive treatment strategies not only for cancer but also for neurodegenerative diseases,autoimmune diseases,cardiovascular diseases,and metabolic disorders.These interventions have demonstrated substantial potential in modulating metabolism,disease trajectory,and therapeutic responses.Metabolic reprogramming is a hallmark of malignant progression,and a deeper understanding of this phenomenon in tumors and its effects on immune regulation is a significant challenge that impedes cancer eradication.Dietary intake,as a key environmental factor,can influence tumor metabolism.Emerging evidence indicates that dietary interventions might affect the nutrient availability in tumors,thereby increasing the efficacy of cancer treatments.However,the intricate interplay between dietary interventions and the pathogenesis of cancer and other diseases is complex.Despite encouraging results,the mechanisms underlying diet-based therapeutic strategies remain largely unexplored,often resulting in underutilization in disease management.In this review,we aim to illuminate the potential effects of various dietary interventions,including calorie restriction,fasting-mimicking diet,ketogenic diet,protein restriction diet,high-salt diet,high-fat diet,and high-fiber diet,on cancer and the aforementioned diseases.We explore the multifaceted impacts of these dietary interventions,encompassing their immunomodulatory effects,other biological impacts,and underlying molecular mechanisms.This review offers valuable insights into the potential application of these dietary interventions as adjunctive therapies in disease management.

Particle Distribution Informed by Chain Rigidity in Diblock Copolymer Melts: The Effect of Entropy

引用

Chinese Journal of Polymer Science 2024年第3期42卷 388-399,I0009页

作者： yuguo Chen Shuanhu Qi ying jiang School of Chemistry Beihang UniversityBeijing 100191China

We study the effect of chain rigidity on tailoring the nanoparticle locations for neutral and selective particles embedded in the lamellar morphology formed by semiflexible diblock copolymer chains using self-consistent field calculations. The nanoparticles are modeled through a cavity function, and the semiflexible chains are represented by the continuous Kratsky-Porod chain model. In general situation, the nanoparticles prefer to stay at the interface in order to reduce the interface areas and thus the system free energy. However, the particle distribution at the domain center is subtle, and the underlying physics is intrinsically different depending on the polymer flexibility. In the case of flexible chains, the entropy just contributes a constant shift to the free energy when the nanoparticles move around the domain center indicating that the local metastable state if appears at the domain center is wholly attributed to the local minimum in the enthalpy. If the polymers are rigid, the variation of the particle distribution at the domain center has a close relation with the polymer rigidity and nanoparticle size. In the case of strongly rigid polymers with small nanoparticles, a nearly uniform particle distribution at the domain center is observed, while in other cases, a local enhancement of particle distribution there is found. In contrast to the case of flexible chains, further analysis reveals the crucial role of entropy in controlling the shape of particle distributions at the phase domain. Specifically, the local metastable state appears in the domain center is determined by the large entropy there which arises from the weak coupling of bond orientations that allows the polymer chains to be relatively relaxed. When the particle becomes selective, its distribution in the phase domain exhibits a shift almost uniformly rather than changes its profile, and the underlying physics still holds. In all, our study establishes a strong coupling between the chain rigidity and effect of entropy.

Low-dimensional perovskite(PVK)materials have attracted significant research interest,because of their quantum-confined effect,tunable band gap structures,and higher stability than that of three-dimensional(3D)PVKs.In semiconductor optoelectronic devices,high speed and small size are closely interlinked.The development of high-speed devices requires researchers to fully understand the properties of materials,especially the dynamic processes such as carrier recombination,separation,and transport,which often play a crucial role in the performance of devices.As an indispensable part of dynamic research,spin relaxation is also of great significance in studying the properties of materials and explore possible applications.Lead halide PVK materials have strong spin-orbit coupling(SOC),which provides a basis for information storage and processing by using spin degrees of freedom.Therefore,studying the carrier and spin dynamics of low-dimensional PVKs is an effective way to understand the internal properties of low-dimensional PVKs clearly.This paper summarizes the latest research progress on the ultrafast carrier and spin dynamics in low-dimensional PVKs,to comprehensively understand their carrier and spin behaviors and present an outlook for relevant studies in this area.

Intestinal failure-associated liver disease(IFALD)is a common complication of long-term parenteral nutrition that is associated with significant morbidity and mortality.It is mainly characterized by cholestasis in children and steatohepatitis in adults.Unfortunately,there is no effective approach to prevent or reverse the disease.Regulated cell death(RCD)represents a fundamental biological paradigm that determines the outcome of a variety of liver diseases.Nowadays cell death is reclassified into several types,based on the mechanisms and morphological phenotypes.Emerging evidence has linked different modes of RCD,such as apoptosis,necroptosis,ferroptosis,and pyroptosis to the pathogenesis of liver diseases.Recent studies have shown that different modes of RCD are present in animal models and patients with IFALD.Understanding the pathogenic roles of cell death may help uncover the underlying mechanisms and develop novel therapeutic strategies in IFALD.In this review,we discuss the current knowledge on how RCD may link to the pathogenesis of IFALD.We highlight examples of cell death-targeted interventions aiming to attenuate the disease,and provide perspectives for future basic and translational research in the field.
