1Mechanism of floral scent production in Osmanthus fragrans and the production and regulation of its key floral constituents,β-ionone and linalool显示文摘Sweet osmanthus(Osmanthus fragrans Lour.)is among the top ten most well-known flowers in China and is recognized as both an aromatic plant and ornamental flower.Here,manual sectioning,scanning electron microscopy,and transmission electron microscopy of sweet osmanthus petals revealed that large amounts of lipids are present inside the petal cells and on the cell surfaces.However,no secretory structures were observed.Instead,the petal cells protrude slightly outward,and the surfaces of the cells are adorned with highly regular brush-shaped hairs.The surfaces of the‘Yingui’petals possessed mostly curled and more numerous hairs,whereas the‘Dangui’petals possessed fewer brush-shaped and more sparsely arranged hairs.In addition,many granular substances were attached to the brush-shaped hairs,and the granules were denser on the hairs of the‘Yingui’petals compared to the hairs on the‘Dangui’petals.Furthermore,35 aromatic components in the‘Yingui’petals and 30 aromatic components in the‘Dangui’petals were detected via GC-MS.The main aromatic component of the‘Yingui’petals wasβ-ionone,whereas that of the‘Dangui’petals was linalool and its oxides.Transcriptome sequencing and qRT-PCR indicated that the highβ-ionone content in the‘Yingui’petals was due to the overexpression of CCD1 and CCD4 and that the high linalool content in the‘Dangui’petals was due to the overexpression of MECS,HDR,IDI1,and LIS1,which function upstream of the linalool synthetic pathway.In particular,the expression levels of CCD4 and LIS1 were upregulated by 5.5-and 5.1-fold in the‘Yingui’and‘Dangui’petals,respectively.One transcription factor(ERF61)was cloned and named,and the expression pattern of ERF61 in sweet osmanthus petals was found to be generally consistent with that of CCD4.Tobacco transformation experiments,yeast one-hybrid experiments,and electrophoretic mobility shift assays indicated that ERF61 binds to the CCD4 promoter and stimulates CCD4 expression,thereby regulating the synthesis ofβ-ionone in sweet osmanthus petals.Yuanji Han Hongyun Wang Xiaodan Wang Ke Li Meifang Dong Yong Li Qian Zhu Fude Shang 2019Horticulture Research2019,6,1:13
2A novel colloidal gold immunochromatography assay strip for the diagnosis of schistosomiasis japonica in domestic animals显示文摘Background:Schistosomiasis remains a major public health concern in China and an epidemiological survey has revealed that schistosome-infected bovines and goats are the main transmission sources for the disease.Therefore,development of a sensitive technique for the diagnosis of schistosomiasis in domestic animals is necessary.Method:A novel colloidal gold immunochromatography assay(GICA)strip was developed for detecting Schistosoma japonicum in domestic animals.The colloidal gold was conjugated with recombinant streptococcal protein G(rSPG).As the test and control lines,the schistosome soluble egg antigen and rSPG,respectively,were blotted on nitrocellulose membrane.Results:The lowest detectable serum dilution was 1∶640 for schistosome-infected buffaloes.The cross-reaction rate of GICA was 14.29%with Paramphistomum sp.in buffaloes,16.67%with Haemonchus sp.in goats,and 33.33%with Orientobilharzia sp.in goats.These results were slightly lower and similar to those obtained through ELISA.Moreover,the strips for detecting S.japonicum in mice,rabbits,buffaloes,and goats showed high sensitivity(100.00%,100.00%,100.00%,and 100.00%,respectively)and specificity(100.00%,100.00%,94.23%,and 88.64%,respectively).And the sensitivity or specificity of the GICA strips did not present any significant differences after storage for 12 months at room temperature.When compared with ELISA,the GICA strips exhibited similar sensitivity and specificity in the diagnosis of schistosomiasis in mice,rabbits,buffaloes,and goats.Besides,only 5μl of serum are required for the test and the detection can be completed within 5 min.Conclusion:This study is the first to develop a GICA strip using gold-rSPG conjugate for the diagnosing of schistosomiasis in domestic animals,and preliminary results showed that the developed strip may be suitable for large-scale screening of schistosomiasis in endemic areas.Rui Xu Jintao Feng Yang Hong Chao Lv Dengyun Zhao Jiaojiao Lin Ke Lu Hao Li Jinming Liu Xiaodan Cao Tao Wang Jinli Zai Zhaozhe Wang Bingguang Jia Qian Han Chuangang Zhu 2017Infectious Diseases of Poverty2017,6,1:12
3Transplantation of placenta-derived mesenchymal stem cells in type 2 diabetes:a pilot study显示文摘Mesenchymal stem cells(MSC)have been used in clinical trials for severe diabetes,a chronic disease with high morbidity and mortality.Bone marrow is the traditional source of human MSC,but human term placenta appears to be an alternative and more readily available source.Here,the therapeutic effect of human placenta-derived MSC(PD-MSC)was studied in type 2 diabetes patients with longer duration,islet cell dysfunction,high insulin doses as well as poor glycemic control in order to evaluate the safety,efficacy and feasibility of PD-MSC treatment in type 2 diabetes(T2D).Ten patients with T2D received three intravenous infusions of PDSC,with one month interval of infusion.The total number of PDSC for each patient was(1.22–1.51)×10^(6)/kg,with an average of 1.35×10^(6)/kg.All of the patients were followed up after therapy for at least 3 months.A daily mean dose of insulin used in 10 patients was decreased from 63.7±18.7 to 34.7±13.4 IU(P<0.01),and the C-peptide level was increased from 4.1±3.7 ng/mL to 5.6±3.8 ng/mL(P<0.05)respectively after therapy.In 4 of 10 responders their insulin doses reduced more than 50%after infusion.The mean levels of insulin and C-peptide at each time point in a total of 10 patients was higher after treatment(P<0.05).No fever,chills,liver damage and other side effects were reported.The renal function and cardiac function were improved after infusion.The results obtained from this pilot clinical trial indicate that transplantation of PD-MSC represents a simple,safe and effective therapeutic approach for T2D patients with islet cell dysfunction.Further large-scale,randomized and well-controlled clinical studies will be required to substantiate these observations.Ranhua JIANG Zhibo HAN Guangsheng ZHUO Xiaodan QU Xue LI Xin WANG Yuankang SHAO Shimin YANG Zhong Chao HAN 2011Frontiers of Medicine2011,5,1:5
4Anti-oxidant and anti-inflammatory activities of ultrasonicassistant extracted polyphenol-rich compounds from Sargassum muticum显示文摘Polypehnol is an important,potentially bioactive component of Sargassum muticum.In this study,ultrasonic assisted extraction of polyphenol-rich substances was performed using a 38%ethanol solution at a solid:liquid ratio of 1:30 at 68℃ for 32min,determined by single-factor and response surface methodology(RSM)optimization.The content of polyphenol was 5.66mg/g in the crude extract.Further extraction showed that the polyphenol mainly distributed in ethyl acetate(SKEE)and water phases(SKEW).The anti-oxidation test by electron spin resonance(ESR)spectrum showed that the SKEE had the strongest scavenging activity on DPPH(1,1-diphenyl-2-picrylhydrazyl)and alkyl radicals.SKEE was shown noncytotoxic but could inhibit the generation of cellular ROS,showing protective effects in H2O2 and AAPHinduced Vero cells and UV-B irradiated HaCaT cells.SKEE also signifi cantly inhibited the release of NO of LPS-induced RAW 264.7 cells.Therefore,the polyphenol-rich extracts in ethanol and ethyl acetate showed excellent anti-oxidant and anti-infl ammatory activities,which is beneficial to the development of high-value bio-substances.YU Yuan WANG Le FU Xiaoting WANG Lei FU Xiaodan YANG Min HAN Zhenlian MOU Haijin JEON You-Jin 2019Journal of Oceanology and Limnology2019,37,3:3
5Exposure measurement, risk assessment and source identification for exposure of traffic assistants to particle-bound PAHs in Tianjin, China显示文摘To investigate the levels of exposure to particulate-bound polycyclic aromatic hydrocarbon(PAH) and to estimate the risk these levels pose to traffic assistants(TAs) in Tianjin(a megacity in North China), a measurement campaign(33 all-day exposure samples, 25 occupational-exposure samples and 10 indoor samples) was conducted to characterize the TAs' exposure to PAHs, assess the cancer risk and identify the potential sources of exposure. The average total exposure concentration of 14 PAHs was approximately 2871 ± 928 ng/m3(on-duty), and 1622 ± 457 ng/m3(all-day). The indoor PAHs level was 1257 ± 107 ng/m3. After 8000 Monte Carlo simulations, the cancer risk resulting from exposure to PAHs was found to be approximately 1.05 × 10-4. A multivariate analysis was applied to identify the potential sources, and the results showed that, in addition to vehicle exhaust, coal combustion and cooking fumes were also another two important contributors to personal PAH exposure. The diagnostic ratios of PAH compounds agree with the source apportionment results derived from principal component analysis.Xiaodan Xue Yan You Jianhui Wu Bin Han Zhipeng Bai Naijun Tang Liwen Zhang 2014Journal of Environmental Sciences2014,26,2:2

7Recent progress in perovskite solar cells:from device to commercialization显示文摘Perovskite solar cells(PSCs) are undergoing rapid development and the power conversion efficiency reaches 25.7% which attracts increasing attention on their commercialization recently.In this review,we summarized the recent progress of PSCs based on device structures,perovskite-based tandem cells,large-area modules,stability,applications and industrialization.Last,the challenges and perspectives are discussed,aiming at providing a thrust for the commercialization of PSCs in the near future.Xinhui Luo Xuesong Lin Feng Gao Yang Zhao Xiaodong Li Liqing Zhan Zexiong Qiu Jin Wang Cong Chen Lei Meng Xiaofeng Gao Yu Zhang Zijian Huang Rundong Fan Huifen Liu Yanrun Chen Xiaoxue Ren Jiahong Tang Chun-Hao Chen Dong Yang Yongguang Tu Xiao Liu Dongxue Liu Qing Zhao Jingbi You Junfeng Fang Yongzhen Wu Hongwei Han Xiaodan Zhang Dewei Zhao Fuzhi Huang Huanping Zhou Yongbo Yuan Qi Chen Zhaokui Wang Shengzhong(Frank)Liu Rui Zhu Jotaro Nakazaki Yongfang Li Liyuan Han 2022Science China Chemistry2022,65,12:1
8Antibacterial and Antioxidant Effects of Three Chlorogenic Acid Extracts显示文摘[Objectives] To study the antibacterial and antioxidant effects of chlorogenic acid extracts of Gynura procumbens,Lonicera japonica,and Eucommia ulmoides leaves,and provide a reference for their usage as natural food preservatives and antioxidants. [Methods]The disc diffusion method was applied to study the antibacterial activity of chlorogenic acid extracts of G. procumbens,L. japonica,and E. ulmoides leaves against several common pathogens. In the antioxidant effects,study was carried out on the anti-lipid peroxidation,reducing capacity,and DPPH free radical scavenging capacity of chlorogenic acid extracts of G. procumbens,L. japonica,and E. ulmoides leaves,respectively.[Results]Three chlorogenic acid extracts had strong inhibitory effects on bacteria,especially the inhibition on Staphylococcus aureus. At the concentration of 100 mg/m L,the bacteriostatic ring of chlorogenic acid extracts of G. procumbens,L. japonica,and E. ulmoides leaves reached 21. 4,23. 6 and 24. 7 mm respectively. Besides,these chlorogenic acid extracts had significant inhibitory effect on Escherichia coli and Salmonella,but the inhibitory effect on the yeast was not obvious; the antibacterial intensity of antibacterial compounds was chlorogenic acid extracts of E. ulmoides > chlorogenic acid extracts of L. japonica > chlorogenic acid extracts of G. procumbens. Among these three chlorogenic acid extracts,the chlorogenic acid extracts of E. ulmoides had higher anti-lipid peroxidation,reducing capacity,and DPPH free radical scavenging capacity than other two chlorogenic acid extracts. [Conclusions] This paper reveals that among chlorogenic acid extracts of G. procumbens,L. japonica,and E. ulmoides leaves,the chlorogenic acid extracts of E. ulmoides leaves have a stronger antibacterial activity and antioxidant activity.Juwu HU Xiaodan HAN Xionghui LI Binhua HUANG 2018Medicinal Plant2018,9,3:1
9Composite electron transport layer for efficient N-I-P type monolithic perovskite/silicon tandem solar cells with high open-circuit voltage显示文摘Perovskite/silicon tandem solar cells(PSTSCs) have exhibited huge technological potential for breaking the Shockley-Queisser limit of single-junction solar cells. The efficiency of P-I-N type PSTSCs has surpassed the single-junction limit, while the performance of N-I-P type PSTSCs is far below the theoretical value. Here, we developed a composite electron transport layer for N-I-P type monolithic PSTSCs with enhanced open-circuit voltage(VOC) and power conversion efficiency(PCE). Lithium chloride(Li Cl) was added into the tin oxide(SnO_(2)) precursor solution, which simultaneously passivated the defects and increased the electron injection driving force at the electron transfer layer(ETL)/perovskite interface.Eventually, we achieved monolithic PSTSCs with an efficiency of 25.42% and V_(OC) of 1.92 V, which is the highest PCE and VOCin N-I-P type perovskite/Si tandem devices. This work on interface engineering for improving the PCE of monolithic PSTSCs may bring a new hot point about perovskite-based tandem devices.Bingbing Chen Pengyang Wang Renjie Li Ningyu Ren Yongliang Chen Wei Han Lingling Yan Qian Huang Dekun Zhang Ying Zhao Xiaodan Zhang 2021Journal of Energy Chemistry2021,30,12:1
10BIG1 mediates sepsis-induced lung injury by modulating lipid raft-dependent macrophage inflammatory responses显示文摘Sepsis is a systemic inflammatory response syndrome with high mortality.It has been reported that brefeldin A-inhibited guanine nucleotide-exchange factor 1(BIG1)is involved in the pathogenesis of sepsis.However,the mechanism is not fully elucidated.In the present study,we explored the role of BIG1 in mediating lipid raft-dependent macrophage inflammatory response and its impact on lung injury in murine sepsis.In vitro studies revealed that BIG1 deficiency reduces the upregulation and secretion of tumor necrosis factor alpha(TNF-α),interleukin-6(IL-6),and IL-1β and inhibits the activation of the toll-like receptor 4(TLR4)/myeloid differentiation primary response 88-dependent nuclear factor kappa-B signaling pathway induced by the lipopolysaccha-ride(LPS)treatment.Further experiments revealed that the inhibitory effects of BIG1 deficiency on LPS-induced inflammation are due to the upregulation of adenosine triphosphate-binding cassette transporter A1.This promotes the free-cholesterol efflux from lipid rafts and results in the reduction of lipid raft TLR4 content.The decrease in TLR4 content in lipid raft thereby inhibits the LPS-induced inflammatory response.Furthermore,using the cecal ligation and puncture-induced polymicrobial sepsis mouse model,we found that conditional knockout(cKO)of the myeloid cell BIG1 significantly reduced the serum concentrations of TNF-α,IL-6,and IL-1β,and downregulated their mRNA expressions in the lungs.Pathological analysis confirmed that the BIG1 cKO alleviated the sepsis-induced lung injury.These results revealed the crucial new role of BIG1 in mediating lipid raft-dependent macrophage inflammatory response.Hence,BIG1 may be a potential promising therapeutic target for the treatment of septic lung injury.Minli Sun Xiaodan Han Di Zhou Jing Zhong Lixin Liu Yirui Wang Jiahui Ni Xiaoyan Shen Chao Liang Hao Fang 2021Acta Biochimica et Biophysica Sinica2021,53,8:1

12Impact of genetic patterns on sorafenib efficacy in patients with FLT3-ITD acute myeloid leukemia undergoing allogeneic hematopoietic stem cell transplantation: a multi-center, cohort study显示文摘Sorafenib therapy improves overall survival(OS)in patients with FLT3 internal tandem duplication(ITD)acute myeloid leukemia(AML)undergoing allogeneic hematopoietic stem cell transplantation.We explored the efficacy of sorafenib therapy in this population with different concomitant genetic patterns.In this multi-center,cohort study,we enrolled patients with FLT3-ITD AML undergoing allogenic hematopoietic cell transplantation.Patients with sorafenib maintenance post-transplantation for at least four weeks were allocated to the sorafenib group,and otherwise to the control group.Ruoyang Shao Yu Zhang Jinping He Fen Huang Zhiping Fan Kaibo Yang Yajing Xu Na Xu Yi Luo Lan Deng Xi Zhang Jia Chen Mingzhe Han Xudong Li Sijian Yu Hui Liu Xinquan Liang Xiaodan Luo Pengcheng Shi Zhixiang Wang Ling Jiang Xuan Zhou Ren Lin Yan Chen Sanfang Tu Jing Sun Yu Wang Qifa Liu Li Xuan 2023Signal Transduction and Targeted Therapy2023,8,10:0
13Recent progress on efficient perovskite/organic tandem solar cells显示文摘The concept of tandem solar cells(TSCs) is an effective way to substantially further improve the efficiency of solar cells. The excellent optoelectronic properties and bandgap tunability of perovskites make them promising for constructing efficient TSCs. Currently, TSCs based on perovskite have been extensively studied. Besides, the performance of organic solar cells has been greatly improved recently due to the wider and more efficient spectral utilization. Accordingly, research on perovskite/organic TSCs has garnered significant attention. It has potential application advantages in emerging fields such as wearable devices by virtue of flexibility. In addition, orthogonal solvents can be adopted to realize the separate preparation of subcells with the solution method, which greatly reduces fabrication complexity;moreover, fabrication with less equipment significantly cuts down the device cost. Meanwhile, organics with more adjustability on the optoelectronic properties provide more tuning strategies for high-performance perovskite/organic TSCs. However, comprehensive and timely reviews on the perovskite/organic TSCs are deficient. Therefore, we expect to accomplish a review on this innovative TSCs to facilitate researchers with a deeper understanding of perovskite/organic TSCs. Herein, we firstly review the significant progress of perovskite and organic solar cells. Then, current achievements of perovskite/organic TSCs are summarized and introduced with a particular focus on the device structure design. Finally, we discuss existential challenges and propose effective strategies for future engineering.Rongbo Wang Meidouxue Han Ya Wang Juntao Zhao Jiawei Zhang Yi Ding Ying Zhao Xiaodan Zhang Guofu Hou 2023Journal of Energy Chemistry2023,,8:0
14Hyperosmolarity promotes macrophage pyroptosis by driving the glycolytic reprogramming of corneal epithelial cells in dry eye disease显示文摘Tear film hyperosmolarity plays a core role in the development of dry eye disease(DED)by mediating the disruption of ocular surface homeostasis and triggering inflammation in ocular surface epithelium.In this study,the mechanisms involving the hyperosmolar microenvironment,glycolysis mediating metabolic reprogramming,and pyroptosis were explored clinically,in vitro,and in vivo.Data from DED clinical samples indicated that the expression of glycolysis and pyroptosis-related genes,including PKM2 and GSDMD,was significantly upregulated and that the secretion of IL-1βsignificantly increased.In vitro,the indirect coculture of macrophages derived from THP-1 and human corneal epithelial cells(HCECs)was used to discuss the interaction among cells.The hyperosmolar environment was found to greatly induce HCECs’metabolic reprogramming,which may be the primary cause of the subsequent inflammation in macrophages upon the activation of the related gene and protein expression.2-Deoxy-d-glucose(2-DG)could inhibit the glycolysis of HCECs and subsequently suppress the pyroptosis of macrophages.In vivo,2-DG showed potential efficacy in relieving DED activity and could significantly reduce the overexpression of genes and proteins related to glycolysis and pyroptosis.In summary,our findings suggested that hyperosmolar-induced glycolytic reprogramming played an active role in promoting DED inflammation by mediating pyroptosis.Yu Han Yu Zhang Kelan Yuan Yaying Wu Xiuming Jin Xiaodan Huang 2023Frontiers of Medicine2023,17,4:0
15Changes in snow parameterization over typical vegetation in the Northern Hemisphere显示文摘季节性降雪对气候变化很敏感,常被当作气候变化的信号.由于其局地特征差异显著,不同下垫面类型的积雪过程也不尽相同.北半球中高纬度的典型下垫面(开阔灌丛,常绿针叶林和混交林)在积雪覆盖率和雪深之间有着独特的关系曲线,这种关系不仅代表了积雪过程和融雪过程的特征变化,更能用于模式进行积雪预测.研究发现,北半球中高纬度的增温改变了积雪参数化关系,进一步影响了局地能量和水循环,造成开阔灌丛的北缩和常绿针叶林及混交林的扩张.然而,目前模式中的积雪参数化并不能很好地再现全球变暖影响下融雪阶段出现的加速融化过程,并且进一步影响对春季融雪的生态影响的理解.Xiaodan Guan Xinrui Zeng Rui Shi Han Chen Zhimin Wei 2023Atmospheric and Oceanic Science Letters2023,16,2:0
16The efficacy of Kanglaite injection during treatment with tyrosine kinase inhibitor in elderly patients with non-small cell lung cancer显示文摘Objective Epidermal growth factor receptor–tyrosine kinase inhibitors(EGFR–TKIs) are widely used in the treatment of EGFR mutation-positive non-small cell lung cancer(NSCLC) patients. The Kanglaite injection(KLT) is a novel broad-spectrum anti-cancer injection produced from traditional Chinese medicinal herbs(coix seed). After its approval in 1995, KLT has become the most popular anti-cancer drug in China. As of this writing, no standard treatment guideline is available for elder patients with NSCLC, and the role of traditional Chinese medicinal herbs, including KLT, combined with TKI treatment remains unknown. This retrospective study evaluated the efficacy and safety of KLT in elderly NSCLC patients during TKI treatment.Methods Thirty elderly patients aged 71-79 years with histopathologically confirmed NSCLC attending the General Hospital of the Shenyang Military Region were enrolled in the study and received EGFR-TKI treatment. All participants received 200 m L KLT injections at the same time on days 1–21. Erlotinib(150 mg) or gefitinib(250 mg) was administered daily from days 1 to 21, and the cycle was repeated every 21 days. The endpoint of the primary study was the disease control rate.Results Thirty elderly patients were enrolled in this study. The objective response rate was 21.3% [95% confidence interval(CI): 8.6% to 35.2%], whereas the disease control rate was 80.4%(95% CI: 71.8% to 97.0%). The grade 3 or 4 adverse effects included leucopenia(13.7%), neutropenia(13.4%), anemia(2.9%), and nausea or vomiting(2.7%). Conclusion The administration of KLT combined with erlotinib or gefitinib showed high efficacy in elderly NSCLC patients. The adverse effects of the drug combination were well tolerated by the patients. KLT combined with TKI treatment might provide a satisfactory therapeutic strategy for elderly NSCLC patients.Wei Zhou Tao Han Zhaozhe Liu Xiaodan Yang Yu Liu Wei Wang Benqiang Yang Xiaodong Xie 2017Oncology and Translational Medicine2017,3,3:0
17The application of 3D printing in the development of RECIST standard for evaluating tumor efficacy显示文摘Three-dimensional(3D)printing technology,as a novel technical method,can convert conventional computed tomography(CT)or magnetic resonance imaging(MRI)scans to computer-aided design files and develop a 2D spatial structure into a 3D imaging structure.In recent years,the technology has been widely used in numerous areas,including head and neck surgery,orthopedics,and bio-medicinal research.This article uses examples of 3D printed tumor models to develop Response Evaluation Criteria In Solid Tumors(RECIST)standards to evaluate the changes in tumors.RECIST standard is currently recognized as the standard for assessment of chemotherapy.Under the RECIST standard,changes occurring in tumors before and after the surgery,are evaluated.The assessment depends upon a CT evaluation of the changes in the lesions with the largest diameters.In addition,the disease progression and stability of remission is also assessed.Three-dimensional printing technology is more intuitive in the evaluation of changes to human tumors following chemotherapy and targeted therapy.However,a few reports are available.Xiaodan Yang Tao Han Yue Zhang Yanming Zhang Gao Li Yongye Liu Zhaozhe Liu Zhendong Zheng 2020Oncology and Translational Medicine2020,6,1:0
18Study on Winter Operation Process of the Surface Flow Constructed Wetland in Tianjin Area显示文摘[Objective] The research aimed to study winter operation process of the surface flow constructed wetland in Tianjin area.[Method] In view of climate characteristics in Tianjin,by the way of running under the ice,winter operation experiment of the surface flow constructed wetland in Tianjin was conducted,with the expectation to get some useful process parameters to run such systems in North China in winter.[Result] Although purification effect of the sewage by surface flow constructed wetland in winter was worse than that in other seasons(average reduction of about 20%),surface flow constructed wetland running under the ice was feasible in Tianjin area.When surface flow constructed wetland in North China ran under ice in winter,it was suggested that the outlet must be located in a low position to prevent to be completely frozen,and running water depth should not be less than 50-60 cm.The hydraulic load could be raised on the basis of reflux,and hydraulic retention time should maintain less than 4 d to keep water-soil interface not freezing.Inlet water depth should be increased as much as possible to improve temperature in the system.[Conclusion] The research could provide reference for promotion and application of the surface flow constructed wetland in North China.Xiaodan Qin Yichao Sun Li Li Xiaolong Shao Dan Yu Qiongqiong Liu Honglei Liu Lin Han 2013Meteorological and Environmental Research2013,4,7:0
19Pistachio genomes provide insights into nut tree domestication and ZW sex chromosome evolution显示文摘Pistachio is a nut crop domesticated in the Fertile Crescent and a dioecious species with ZW sex chromosomes.We sequenced the genomes of Pistacia vera cultivar(cv.)Siirt,the female parent,and P.vera cv.Bagyolu,the male parent.Two chromosome-level reference genomes of pistachio were generated,and Z and W chromosomes were assembled.The ZW chromosomes originated from an autosome following the first inversion,which occurred approximately 8.18 Mya.Three inversion events in the W chromosome led to the formation of a 12.7-Mb(22.8%of the W chromosome)non-recombining region.These W-specific sequences contain several genes of interest that may have played a pivotal role in sex determination and contributed to the initiation and evolution of a ZW sex chromosome system in pistachio.The W-specific genes,including defA,defA-like,DYT1,two PTEN1,and two tandem duplications of six VPS13A paralogs,are strong candidates for sex determination or differentiation.Demographic history analysis of resequenced genomes suggest that cultivated pistachio underwent severe domestication bottlenecks approximately 7640 years ago,dating the domestication event close to the archeological record of pistachio domestication in Iran.We identified 390,211,and 290 potential selective sweeps in 3 cultivar subgroups that underlie agronomic traits such as nut development and quality,grafting success,flowering time shift,and drought tolerance.These findings have improved our understanding of the genomic basis of sex determination/differentiation and horticulturally important traits and will accelerate the improvement of pistachio cultivars and rootstocks.Salih Kafkas Xiaokai Ma Xingtan Zhang Hayat Topc¸u Rafael Navajas-Pérez Ching Man Wai Haibao Tang Xuming Xu Mortaza Khodaeiaminjan Murat Güney Aibibula Paizila Harun Karcı Xiaodan Zhang Jing Lin Han Lin Roberto de la Herrán Carmelo Ruiz Rejón Jerson Alexander García-Zea Francisca Robles Coral del Val Muñoz Agnes Hotz-Wagenblatt Xiangjia Jack Min HakanÖzkan Elmira Ziya Motalebipour Hatice Gozel Nergiz C¸oban Nesibe Ebru Kafkas Andrej Kilian HuaXing Huang Xuanrui Lv Kunpeng Liu Qilin Hu Ewelina Jacygrad William Palmer Richard Michelmore Ray Ming 2023Plant Communications2023,4,3:0
20Methcathinone Increases Visually-evoked Neuronal Activity and Enhances Sensory Processing Efficiency in Mice显示文摘Methcathinone(MCAT)belongs to the designer drugs called synthetic cathinones,which are abused worldwide for recreational purposes.It has strong stimulant effects,including enhanced euphoria,sensation,alertness,and empathy.However,little is known about how MCAT modulates neuronal activity in vivo.Here,we evaluated the effect of MCAT on neuronal activity with a series of functional approaches.C-Fos immunostaining showed that MCAT increased the number of activated neurons by 6-fold,especially in sensory and motor cortices,striatum,and midbrain motor nuclei.In vivo single-unit recording and two-photon Ca^(2+) imaging revealed that a large proportion of neurons increased spiking activity upon MCAT administration.Notably,MCAT induced a strong de-correlation of population activity and increased trial-to-trial reliability,specifically during a natural movie stimulus.It improved the information-processing efficiency by enhancing the single-neuron coding capacity,suggesting a cortical network mechanism of the enhanced perception produced by psychoactive stimulants.Jun Zhou Wen Deng Chen Chen Junya Kang Xiaodan Yang Zhaojuan Dou Jiancheng Wu Quancong Li Man Jiang Man Liang Yunyun Han 2023Neuroscience Bulletin2023,39,4:0
