1Structural,Functional,and Molecular Imaging of Autism Spectrum Disorder显示文摘Autism spectrum disorder(ASD)is a heterogeneous neurodevelopmental disorder associated with both genetic and environmental risks.Neuroimaging approaches have been widely employed to parse the neurophysiological mechanisms underlying ASD,and provide critical insights into the anatomical,functional,and neurochemical changes.We reviewed recent advances in neuroimaging studies that focused on ASD by using magnetic resonance imaging(MRI),positron emission tomography(PET),or single-positron emission tomography(SPECT).Longitudinal structural MRI has delineated an abnormal developmental trajectory of ASD that is associated with cascading neurobiological processes,and functional MRI has pointed to disrupted functional neural networks.Meanwhile,PET and SPECT imaging have revealed that metabolic and neurotransmitter abnormalities may contribute to shaping the aberrant neural circuits of ASD.Future large-scale,multi-center,multimodal investigations are essential to elucidate the neurophysiological underpinnings of ASD,and facilitate the development of novel diagnostic biomarkers and better-targeted therapy.Xiaoyi Li Kai Zhang Xiao He Jinyun Zhou Chentao Jin Lesang Shen Yuanxue Gao Mei Tian Hong Zhang 2021Neuroscience Bulletin2021,37,7:4
2Resveratrol promotes the survival and neuronal differentiation of hypoxia-conditioned neuronal progenitor cells in rats with cerebral ischemia显示文摘Hypoxia conditioning could increase the survival of transplanted neuronal progenitor cells(NPCs)in rats with cerebral ischemia but could also hinder neuronal differentiation partly by suppressing mitochondrial metabolism.In this work,the mitochondrial metabolism of hypoxia-conditioned NPCs(hcNPCs)was upregulated via the additional administration of resveratrol,an herbal compound,to resolve the limitation of hypoxia conditioning on neuronal differentiation.Resveratrol was first applied during the in vitro neuronal differentiation of hcNPCs and concurrently promoted the differentiation,synaptogenesis,and functional development of neurons derived from hcNPCs and restored the mitochondrial metabolism.Furthermore,this herbal compound was used as an adjuvant during hcNPC transplantation in a photothrombotic stroke rat model.Resveratrol promoted neuronal differentiation and increased the long-term survival of transplanted hcNPCs.18-fluorine fluorodeoxyglucose positron emission tomography and rotarod test showed that resveratrol and hcNPC transplantation synergistically improved the neurological and metabolic recovery of stroke rats.In conclusion,resveratrol promoted the neuronal differentiation and therapeutic efficiency of hcNPCs in stroke rats via restoring mitochondrial metabolism.This work suggested a novel approach to promote the clinical translation of NPC transplantation therapy.Yao Yao Rui Zhou Rui Bai Jing Wang Mengjiao Tu Jingjing Shi Xiao He Jinyun Zhou Liu Feng Yuanxue Gao Fahuan Song Feng Lan Xingguo Liu Mei Tian Hong Zhang 2021Frontiers of Medicine2021,15,3:3
3Preparation of hollow fiber membranes from mullite particles with aid of sintering additives显示文摘Porous mullite hollow fiber membranes were prepared with a combined phase-inversion and sintering method,using three sintering additives including yttrium stabilized zirconia(YSZ),small mullite particles(SMP),and titanium oxide(TiO2)to promote the particle sintering.The results indicated that all the three additives could improve the sintering performance of mullite hollow fiber membranes due to the decrease in activation energy of mullite grains.Both YSZ and T i02 could react with mullite grains to generate composite oxides(e.g.,ZrSi04 and Al2Ti05)during sintering,following a reaction-sintering mechanism.Interestingly,the newly generated ZrSiO4 was instable and further decomposed into monoclinic ZrO2 and SiO2 in the sintering process.The decomposition could avoid excessive embedment of composite oxides among mullite grains which have negative impact on mechanical strength of mullite hollow fibers.Overall,the doping of YSZ provided a better promotion effect on the sintering of mullite hollow fiber membranes,where the microstructural and mechanical properties are insensitive to the doping content and sintering temperatures,so it could be used as the candidate for the large-scale preparation of mullite hollow fibers.Hua LIU Jinyun LIU Zhou HONG Shengxian WANG Xuechao GAO Xuehong GU 2021Journal of Advanced Ceramics2021,10,1:3
4Synthesis and Diameter-dependent Thermal Conductivity of InAs Nanowires显示文摘In this work, we synthesized high-quality In As nanowires by a convenient chemical vapor deposition method,and developed a simple laser heating method to measure the thermal conductivity of a single In As nanowire in air. During the measurement, a focused laser was used to heat one end of a freely suspended nanowire, with its other end embedded into a carbon conductive adhesive. In order to obtain the thermal conductivity of In As nanowires, the heat loss in the heat transfer process was estimated, which includes the heat loss through air conduction, the heat convection, and the radiation loss. The absorption ratio of the laser power in the In As nanowire was calculated. The result shows that the thermal conductivity of In As nanowires monotonically increases from 6.4 W m-1K-1to 10.5 W m-1K-1with diameters increasing from 100 nm to 190 nm, which is ascribed to the enhanced phonon-boundary scattering.Pinyun Ren Xiaoli Zhu Jinyun Han Jinyou Xu Liang Ma Honglai Li Xiujuan Zhuang Hong Zhou Qinglin Zhang Minggang Xia Anlian Pan 2014Nano-Micro Letters2014,6,4:2
5Nano-micrometer surface roughness gradients reveal topographical influences on differentiating responses of vascular cells on biodegradable magnesium显示文摘Distinctively directing endothelial cells(ECs)and smooth muscle cells(SMCs),potentially by surface topography cue,is of central importance for enhancing bioefficacy of vascular implants.For the first time,surface gradients with a broad range of nano-micrometer roughness are developed on Mg,a promising next-generation biodegradable metal,to carry out a systematic study on the response of ECs and SMCs.Cell adhesion,spreading,and proliferation are quantified along gradients by high-throughput imaging,illustrating drastic divergence between ECs and SMCs,especially in highly rough regions.The profound role of surface topography overcoming the biochemical cue of released Mg2+is unraveled at different roughness ranges for ECs and SMCs.Further insights into the underlying regulatory mechanism are gained at subcellular and gene levels.Our work enables highefficient exploration of optimized surface morphology for modulating favored cell selectivity of promoting ECs and suppressing SMCs,providing a potential strategy to achieve rapid endothelialization for Mg.Ke Zhou Yutong Li Lei Zhang Liang Jin Feng Yuan Jinyun Tan Guangyin Yuan Jia Pei 2021Bioactive Materials2021,6,1:2
6Replacing fishmeal with soybean meal affects survival, antioxidant capacity, intestinal microbiota, and mRNA expression of TOR and S6K1 in Macrobrachium rosenbergii显示文摘Using alternative plant-derived dietary protein to replace fishmeal,combined with practical evaluation indexes,is a recent focus for aquaculture practices.An 8-week feeding experiment with giant freshwater prawn Macrobrachium rosenbergii post-larvae was conducted to determine the eff ects of replacing fi shmeal(FM)with soybean meal in the feed,in terms of growth performance,antioxidant capacity,intestinal microbiota,and mRNA expression of target of rapamycin(TOR)and ribosomal protein S6 kinase B1(S6K1).Four isonitrogenous diets with isocaloric value were prepared to contain 100%,75%,50%,or 25%FM as the protein source(dietary treatments FM100,FM75,FM50,and FM25,respectively).Each diet was fed to post-larval prawns(mean weight 0.045±0.002 g)twice a day in four replicates.No signifi cant diff erence in weight gain was observed among all groups,but the survival rate of prawns fed the FM50 and FM25 diets was signifi cantly lower than that of prawns fed the FM diet.The mRNA expression of both TOR and S6K1 were the lowest in hepatopancreas of prawns fed the FM25 diet.Superoxide dismutase activity of prawns fed the FM25 diet was significantly lower than that of prawns fed FM50.In contrast,the malondialdehyde content was signifi cantly higher in prawns fed FM25 as compared with those fed FM75.The proportion of fishmeal in the diet did not affect the composition of core(phylum-level)intestinal microbiota,but greater fishmeal replacement with soybean meal had a potential risk to increase the relative abundance of opportunistic pathogens in the gut when considered at the genus level.These results suggest that fishmeal replacement with soybean meal should not exceed 50%in a diet for post-larval M.rosenbergii.Zhili DING Dongsheng ZHOU Jinxian ZHENG Xuefeng CHEN Youqin KONG Changle QI Yan LIU Qiongying TANG Guoliang YANG Jinyun YE 2022Journal of Oceanology and Limnology2022,40,2:1
7Subwavelength filter and sensor design based on end-coupled composited ring-groove resonator显示文摘A plasmonic filter and sensor is designed based on an end-coupled ring-groove composited resonator(RGCR).According to the magnetic field distributions of the resonance modes,a horizontal or vertical groove is added to the perfect ring resonator,and the transmission peaks for the 1st and the 2nd modes can be linearly changed by the length of the groove.In this case,the proposed structure can act as an on-chip optical filter with flexible wavelength manipulation.When the groove is rotated with an angle of?/4,Fano resonance arises due to the mode interference.Dual asymmetric sharp transmission peaks are achieved around the wavelength of the former 2nd resonance mode.High figure of merit and high sensitivity are obtained for the structure,and it is believed that the device can find widely applications in the biochemistry sensing area.The corresponding spectra and the propagation characteristics are numerically investigated by using the finite-difference time-domain method.Kunhua Wen Yihua Hu Li Chen Jinyun Zhou Miao He Liang Lei Ziming Meng 2017光电工程2017,44,2:1
8Height connection across sea by using satellite altimetry data sets,ellipsoidal heights,astrogeodetic deflections of the vertical,and an Earth Gravity Model显示文摘Islands and the mainland are separated by seas,and the distances between them might be so long that the height on the mainland cannot be exactly translated to the islands,resulting in different height systems on the mainland and the islands.In this study,we used astrogeodetic deflections of the vertical and ellipsoidal heights of points on the mainland and island near their coastlines to implement height connection across sea areas.First,the modeled gravity and modeled astrogeodetic vertical deflections of segmentation points along connecting routes over the sea between the mainland and the island were determined by Earth Gravity Model(EGM),and the ellipsoidal heights of segmentation points were determined by the satellite altimetry data sets.Second,we used a linear interpolation model to increase the precision of the vertical deflections of segmentation points.Third,we computed the geopotential difference of points between the mainland and the island using a method derived from geopotential theory and the astronomical leveling principle.Finally,we estimated the normal height of the point on the island using the geopotential-difference iterative computation approach.Using observed data of normal heights,ellipsoidal heights,and astrogeodetic vertical deflections referring to height sites in Qingdao,Shandong Province,we conducted a numerical experiment involving the normal height connection across sea regions.We determined the data of the ellipsoidal heights and gravity of segmentation points along the connecting route across the water in the numerical experiment using DTU10.The distance of the height connection across the sea was approximately 10.5 km.According to China's official leveling specifications,the experimental results met the criterion of third-class leveling precision.Jianbo Wang Xinmin Qi Kai Luo Zhengyuan Li Ruikang Zhou Jinyun Guo 2023Geodesy and Geodynamics2023,14,4:0
9Growth and Antimony Bioconcentration Characteristics of Wild Ramie(Boehmeria nivea)under Sb Stress in Different Valence States显示文摘[Objectives] To explore the effects of antimony(Sb) in different valence states on the growth and Sb bioconcentration and transfer of wild ramie(Boehmeria nivea). [Methods] A pot experiment was conducted to study the effects of Sb(Ⅲ) and Sb(Ⅴ) stress on plant height, biomass, leaf SPAD value, Sb contents in various organs, Sb bioconcentration and transfer factors, and other indexes. [Results] Both kinds of Sb treatments showed a trend of 'first increasing and then decreasing' in plant height as Sb concentration increased. The plant heights in Sb(Ⅲ) treatments with a concentration lower than 1 000 mg/kg and Sb(Ⅴ) treatments with concentrations lower than 4 000 mg/kg were significantly higher than that of the control check(CK);and the Sb(Ⅲ) treatment of the high concentration(4 000 mg/kg) resulted in a significant decrease in plant height, while the 8 000 mg/kg Sb(Ⅴ) treatment still showed an increase in plant height, indicating that the toxicity of Sb(Ⅴ) to wild ramie was significantly lower than that of Sb(Ⅲ). The Sb(Ⅲ) treatments with a concentration lower than 2 000 mg/kg had little effect on the dry weight of the aboveground part, while the treatment with a higher concentration showed a significant decrease;and the dry weights in various concentrations of Sb(Ⅴ) treatments showed no significant differences, but they were significantly higher than the CK and corresponding concentration of Sb(Ⅲ) treatment. Both types of Sb stress could promote the increase of SPAD value in wild ramie leaves, and the performance was significantly higher than the CK. As the concentration of Sb treatment increased, the Sb content in both the aboveground and underground parts showed a significant increase;and the comparison of Sb content under corresponding concentrations of the two types of Sb treatments showed that in the aboveground part, Sb(Ⅲ) was higher than Sb(Ⅴ), while in the underground part, the opposite was true. The bioconcentration factor(BF) of Sb decreased with the increase of Sb treatment concentration overall, and the value of Sb(Ⅴ) was smaller than that of Sb(Ⅲ), but both kinds of Sb stress were significantly smaller than the CK. The transfer factor(TF) of Sb in wild ramie showed a trend of 'increasing first and then decreasing' with the concentration of Sb treatment, and various treatments of Sb(Ⅲ) were higher than the CK, with significant differences, while among various treatments of Sb(Ⅴ), except treatment B3, the reduction of which was not significant, other Sb(Ⅴ) treatments showed significant decreases. Comparing the two types of Sb treatments, the BF and TF values of Sb in wild ramie under Sb(Ⅲ) treatments were higher than those under Sb(Ⅴ) treatments, and the TF reached a significant level, indicating that the Sb transport ability of wild ramie under Sb(Ⅲ) treatments was stronger. [Conclusions] This study provides a theoretical basis for the mining of wild ramie Sb restoration genes and the application of large-scale cultivation in ecological restoration.Fulong YANG Jiecheng HAN Yuan WEI Xiaoqi YANG Jinyun PENG Zhi WEI Xiaolian YAN Beiyou ZHANG Qiaoshan LIU Jing ZHOU Guiyuan MENG 2023Asian Agricultural Research2023,15,6:0
10Rare Earth Ion Yb^3+ Doping of Bi2WO6 with Excellent Visible-light Photocatalytic Activity显示文摘The rare earth ion Yb^3+ doped Bi2WO6 photocatalysts were synthesized by hydrothermal method.Moreover,XRD,XPS,FESEM,TEM,Ramam,N2 adsorption-desorption isotherm measurements and UV-vis diffusion reflectance spectra were used to characterize the Yb^3+ doped Bi2WO6 photocatalysts.The morphology,specific surface area,and pore volume distribution were greatly affected after Yb3+ ions doping.Photocatalytic performance of Bi2WO6 was effectively enhanced after Yb3+ ions doping,6% Yb^3+ doped Bi2WO6 had the best photocatalytic performance,and 96.2% Rhodamine B was degradated after irradiated 30 min,which was 1.29 times that of the pristine one.The enhanced photocatalytic performance was due to the increased specific surface area,decreased energy band gap and inhibition of photoelectron-hole recombination after Yb3+ ions doping.HE Jinyun YU Qi ZHOU Yunpeng WANG Yanwu LONG Fei 2020Journal of Wuhan University of Technology(Materials Science)2020,35,2:0
11Mass Production of Bi3NbO7/Bi2Zn(2/3)Nb(4/3)O7 Composites and Their Visible-light Photocatalytic Activity显示文摘Series Bi_3NbO_7/Bi_2Zn_(2/3)Nb_(4/3)O_7 (BN/BZN) composites were synthesized through a facile solid state reaction method. The products were characterized by X-ray diffraction(XRD), field emission scanning electron microscopy(FE-SEM) and UV-vis diffuse reflectance spectroscopy(DRS). When BN: BZN=0.1 mole ratio, the BN/BZN composite showed the best visible-light-driven photocatalytic performance, which decomposed nearly 100% of Rh B(10 ppm, p H=3-4) within 40 min. The results demonstrated that in-situ solid state synthesis of BN/BZN composites could be an efficient strategy to develop new photocatalyst for environmental remediation.彭代江 ZOU Zhengguang HE Jinyun 龙飞 MO Shuyi ZHOU Huanfu 2017Journal of Wuhan University of Technology(Materials Science)2017,32,2:0
