| 1 | The Chinese Society of Clinical Oncology(CSCO):Clinical guidelines for the diagnosis and treatment of gastric cancer,2021显示文摘There exist differences in the epidemiological characteristics,clinicopathological features,tumor biological characteristics,treatment patterns,and drug selections between gastric cancer patients from the Eastern and Western countries.The Chinese Society of Clinical Oncology(CSCO)has organized a panel of senior experts specializing in all sub-specialties of gastric cancer to compile a clinical guideline for the diagnosis and treatment of gastric cancer since 2016 and renews it annually.Taking into account regional differences,giving full consideration to the accessibility of diagnosis and treatment resources,these experts have conducted expert consensus judgment on relevant evidence and made various grades of recommendations for the clinical diagnosis and treatment of gastric cancer to reflect the value of cancer treatment and meeting health economic indexes in China.The 2021 CSCO Clinical Practice Guidelines for Gastric Cancer covers the diagnosis,treatment,follow-up,and screening of gastric cancer.Based on the 2020 version of the CSCO Chinese Gastric Cancer guidelines,this updated guideline integrates the results ofmajor clinical studies from China and overseas for the past year,focused on the inclusion of research data from the Chinese population for more personalized and clinically relevant recommendations.For the comprehensive treatment of non-metastatic gastric cancer,attentions were paid to neoadjuvant treatment.The value of perioperative chemotherapy is gradually becoming clearer and its recommendation level has been updated.For the comprehensive treatment of metastatic gastric cancer,recommendations for immunotherapy were included,and immune checkpoint inhibitors fromthird-line to the first-line of treatment for different patient groups with detailed notes are provided. | Feng-Hua Wang Xiao-Tian Zhang Yuan-Fang Li Lei Tang Xiu-Juan Qu Jie-Er Ying Jun Zhang Ling-Yu Sun Rong-Bo Lin Hong Qiu Chang Wang Miao-Zhen Qiu Mu-Yan Cai QiWu Hao Liu Wen-Long Guan Ai-Ping Zhou Yu-Jing Zhang Tian-Shu Liu Feng Bi Xiang-Lin Yuan Sheng-Xiang Rao Yan Xin Wei-Qi Sheng Hui-Mian Xu Guo-Xin Li Jia-Fu Ji Zhi-Wei Zhou Han Liang Yan-Qiao Zhang Jing Jin Lin Shen Jin Li Rui-Hua Xu | 2021 | Cancer Communications2021,41,8: | 97 |
| 2 | New vacuum solar telescope and observations with high resolution显示文摘The New Vacuum Solar Telescope(NVST) is a one meter vacuum solar telescope that aims to observe fine structures on the Sun. The main goals of NVST are high resolution imaging and spectral observations, including measurements of the solar magnetic field. NVST is the primary ground-based facility used by the Chinese solar research community in this solar cycle. It is located by Fuxian Lake in southwest China, where the seeing is good enough to perform high resolution observations. We first introduce the general conditions at the Fuxian Solar Observatory and the primary science cases of NVST. Then, the basic structures of this telescope and instruments are described in detail. Finally, some typical high resolution data of the solar photosphere and chromosphere are also shown. | Zhong Liu Jun Xu Bo-Zhong Gu Sen Wang Jian-Qi You Long-Xiang Shen Ru-Wei Lu Zhen-Yu Jin Lin-Fei Chen Ke Lou Zhi Li Guang-Qian Liu Zhi Xu Chang-Hui Rao Qi-Qian Hu Ru-Feng Li Hao-Wen Fu Feng Wang Men-Xian Bao Ming-Chan Wu Bo-Rong Zhang | 2014 | Research in Astronomy and Astrophysics2014,14,6: | 37 |
| 3 | Effects of multimodal fast-track surgery on liver transplantation outcomes显示文摘BACKGROUND:Fast-track surgery and enhanced recovery after surgery have been applied to many surgical procedures;however,data on fast-track surgery and enhanced recovery after surgery following liver transplantation is limited.This study aimed to conduct a prospective study to determine the effects of fast-track surgery on prognosis after liver transplantation.METHODS:This was a prospective,single-blinded,randomized study.One hundred twenty-eight patients undergoing liver transplantation were selected for the fast-track(FT group,n=54) or conventional process(NFT group,n=74).The primary endpoints were intensive care unit(ICU) stay and hospital stay.The secondary endpoints were as follows:operative time,anhepatic phase time,intraoperative blood loss,intraoperative blood transfusion volume,postoperative complications,readmission rate,and postoperative mortality.RESULTS:There was no significant difference in preoperative demographics between the two groups.The median ICU stay was 2 days(range 1-7 days) in the FT group and 5 days(range 3-12 days) in the NFT group(P<0.01).Furthermore,the hospital stay was also significantly reduced in the FT group(P<0.01).The operative time,anhepatic phase time,intraoperative blood loss,and intraoperative blood transfusion volume were decreased in the FT group compared with the NFT group(P<0.05).Based on Spearman correlation analysis,the ICU stay and hospital stay may be positively correlated with operative time,anhepatic phase time and intraoperative blood loss.There were no differences in the incidence of postoperative complications,readmissions,and postoperative mortality between the two groups.CONCLUSION:Fast-track procedures effectively reduce the ICU stay and hospital stay without adversely affecting prognosis.This study demonstrated that fast-track protocols are safe and feasible in liver transplantation. | Jian-Hua Rao Feng Zhang Hao Lu Xin-Zheng Dai Chuan-Yong Zhang Xiao-Feng Qian Xue-Hao Wang Ling Lu | 2017 | Hepatobiliary & Pancreatic Diseases International2017,16,4: | 23 |
| 4 | On the timing of the East Asian summer monsoon maximum during the Holocene Does the speleothem oxygen isotope record reflect monsoon rainfall variability?显示文摘The evolution of the East Asian summer monsoon(EASM) during the Holocene has long been of significant interest.Knowledge of past EASM variability not only increases our understanding of monsoon dynamics on a long timescale,but it also provides an environmental and climatic background for research into Chinese cultural development.However,the timing of the EASM maximum remains controversial.The popular concept of an 'early Holocene maximum' is mainly based on speleothemδ^(18)O(δ^(18)O_c) records from caves in southern China;however,the interpretation of δ^(18)O_C as a reliable proxy for EASM intensity is being increasingly challenged.The present paper is a critical review of the climatic significance of the δ^(18)O_C record from China.Firstly,we suggest that precipitation in northern China is an appropriate index of EASM intensity,the variation of which clearly indicates a mid-Holocene monsoon maximum.Secondly,an interregional comparison demonstrates that the precipitation record in northern China is quite different from that in southern China on a range of timescales,and is inconsistent with the spatial similarity exhibited by speleothem oxygen isotope records.Furthermore,both modeling and observational data show that the δ^(18)O_C records from southern China indeed reflect changes in precipitation δ^(18)O(δ^(18)O_P) rather than precipitation amount,and therefore that their use as an EASM proxy is inappropriate.Finally,we address several significant monsoon-related issues-including the driving mechanism of the EASM on an orbital timescale,the climatic significance of speleothem oxygen isotopes,and the relationship between atmospheric circulation and precipitation in monsoonal regions. | CHEN JianHui RAO ZhiGuo LIU JianBao HUANG Wei FENG Song DONG GuangHui HU Yu XU QingHai CHEN FaHu | 2016 | Science China(Information Sciences)2016,59,12: | 18 |
| 5 | Novel multimodal analgesia regimen improves post-TACE pain in patients with hepatocellular carcinoma显示文摘Backgroud: Transarterial chemoembolization(TACE) is the primary palliative treatment for patients with unresectable hepatocellular carcinoma(HCC). However, it is often accompanied by postoperative pain which hinder patient recovery. This study was to examine whether preemptive parecoxib and sufentanilbased patient controlled analgesia(PCA) could improve the pain management in patients receiving TACE for inoperable HCC. Methods: From June to December 2016, 84 HCC patients undergoing TACE procedure were enrolled. Because of the willingness of the individuals, it is difficult to randomize the patients to different groups. We matched the patients' age, gender and pain scores, and divided the patients into the multimodal group( n = 42) and control group( n = 42). Patients in the multimodal group received 40 mg of parecoxib, 30 min before TACE, followed by 48 h of sufentanil-based PCA. Patients in the control group received a routine analgesic regimen, i.e., 5 mg of dezocine during operation, and 100 mg of tramadol or equivalent intravenous opioid according to patient's complaints and pain intensity. Postoperative pain intensity, percentage of patients as per the pain category, adverse reaction, duration of hospital stay, cost-effectiveness, and patient's satisfaction were all taken into consideration when evaluated. Results: Compared to the control group, the visual analogue scale scores for pain intensity was significantly lower at 2, 4, 6, and 12 h(all P < 0.05) in the multimodal group and a noticeably lower prevalence of post-operative nausea and vomiting in the multimodal group(31.0% vs. 59.5%). Patient's satisfaction in the multimodal group was also significantly higher than that in the control group(95.2% vs. 69.0%). No significant difference was observed in the duration of hospital stay between the two groups. Conclusion: Preemptive parecoxib and sufentanil-based multimodal analgesia regime is a safe, efficient and cost-effective regimen for postoperative pain control in HCC patients undergoing TACE. | Jian-Guo Guo Lu-Ping Zhao Yue-Feng Rao Yin-Ping Gao Xue-Jiao Guo Tan-Yang Zhou Zhi-Ying Feng Jun-Hui Sun Xiao-Yang Lu | 2018 | Hepatobiliary & Pancreatic Diseases International2018,17,6: | 18 |
| 6 | Memory materials and devices:From concept to application显示文摘Memory cells have always been an important element of information technology.With emerging technologies like big data and cloud computing,the scale and complexity of data storage has reached an unprecedented peak with a much higher requirement for memory technology.As is well known,better data storage is mostly achieved by miniaturization.However,as the size of the memory device is reduced,a series of problems,such as drain gate-induced leakage,greatly hinder the performance of memory units.To meet the increasing demands of information technology,novel and high-performance memory is urgently needed.Fortunately,emerging memory technologies are expected to improve memory performance and drive the information revolution.This review will focus on the progress of several emerging memory technologies,including two-dimensional material-based memories,resistance random access memory(RRAM),magnetic random access memory(MRAM),and phasechange random access memory(PCRAM).Advantages,mechanisms,and applications of these diverse memory technologies will be discussed in this review. | Zhenhan Zhang Zongwei Wang Tuo Shi Chong Bi Feng Rao Yimao Cai Qi Liu Huaqiang Wu Peng Zhou | 2020 | InfoMat2020,2,2: | 15 |
| 7 | N-acetylcysteine attenuates reactive-oxygen-speciesmediated endoplasmic reticulum stress during liver ischemia-reperfusion injury显示文摘AIM:To investigate the effects of N-acetylcysteine(NAC) on endoplasmic reticulum(ER) stress and tissue injury during liver ischemia reperfusion injury(IRI).METHODS:Mice were injected with NAC(300 mg/kg) intraperitoneally 2 h before ischemia.Real-time polymerase chain reaction and western blotting determined ER stress molecules(GRP78,ATF4 and CHOP).To analyze the role of NAC in reactive oxygen species(ROS)-mediated ER stress and apoptosis,lactate dehydrogenase(LDH) was examined in cultured hepatocytes treated by H2O2 or thapsigargin(TG).RESULTS:NAC treatment significantly reduced the level of ROS and attenuated ROS-induced liver injury after IRI,based on glutathione,malondialdehyde,serum alanine aminotransferase levels,and histopathology.ROS-mediated ER stress was significantly inhibited in NAC-treated mice.In addition,NAC treatment significantly reduced caspase-3 activity and apoptosis after reperfusion,which correlated with the protein expression of Bcl-2 and Bcl-xl.Similarly,NAC treatment significantly inhibited LDH release from hepatocytes treated by H2O2 or TG.CONCLUSION:This study provides new evidence for the protective effects of NAC treatment on hepatocytes during IRI.Through inhibition of ROS-mediated ER stress,NAC may be critical to inhibit the ER-stressrelated apoptosis pathway. | Yong Sun Li-Yong Pu Ling Lu Xue-Hao Wang Feng Zhang Jian-Hua Rao | 2014 | World Journal of Gastroenterology2014,20,41: | 13 |
| 8 | CD30 expression in extranodal natural killer/T-cell lymphoma,nasal type among 622 cases of mature T-cell and natural killer-cell lymphoma at a single institution in South China显示文摘Background:Mature T-cell and natural killer(NK)-cell lymphomas compose a heterogeneous group of non-Hodgkin lymphomas,and extranodal NK/T-cell lymphoma,nasal type(ENKTL) is an aggressive subtype with sporadic CD30 expression.However,the significance of CD30 expression in ENKTL is controversial.We aimed to classify a large cohort of patients with mature T-cell and NK-cell lymphomas according to the 2016 World Health Organization(WHO) classification guidelines and to study the association between CD30 expression and prognosis of patients with ENKTL.Methods:We selected consecutive patients with mature T-cell and NK-cell lymphomas who attended our institution between September 1,2009 and August 31,2013.We classified the lymphomas according to the 2016 revision of the WHO classification of lymphoid neoplasms,analyzed the associations between CD30 expression and clinicopathologic features of ENKTL patients,and evaluated the prognostic implications of CD30 expression.Results:We identified 622 consecutive patients with mature T-cell and NK-cell lymphomas,including 317(51.0%)patients with ENKTL.In addition,CD30 expression was detected in 43(47.3%) of a subset of 91 patients with ENKTL.No clinicopathologic features were associated with CD30 expression,and CD30 positivity showed no prognostic significance in patients with ENKTL.Conclusions:ENKTL is the most common type of mature T-cell and NK-cell lymphoma diagnosed at our institution.CD30 is frequently expressed in ENKTL and represents a therapeutic target;however,it may not be a prognostic marker. | Yanfen Feng Huilan Rao Yiyan Lei Yuhua Huang Fang Wang Yu Zhang Shaoyan Xi Qiuliang Wu Jianyong Shao | 2017 | Chinese Journal of Cancer2017,36,6: | 10 |
| 9 | Comparison of phylobetadiversity indices based on community data from Gutianshan forest plot显示文摘Phylobetadiversity incorporates phylogenetic information and beta diversity,and can account for the ecological similarities between communities with a phylogenetic perspective.Although different phylobetadiversity indices reflect differences in different characteristics between communities,the results of different phylobetadiversity indices are not comparable.In this study we examined phylobetadiversity indices for a 24-hm 2 plot in the Gutianshan National Nature Reserve.It was found the abundanceweighted D pw was almost identical to Rao's D of Rao's quadratic entropy.PhyloSor had a similar ecological meaning and algorithm to UniFrac.Although Dnn was different in definition from UniFrac and PhyloSor,they were all strongly correlated.The effect of species abundance on phylobetadiversity was not significant when scales were relatively small,but was significant at larger scales.These contrasts likely resulted from reductions in evenness in communities as scales increased.P ST and Rao's H better reflected the distance-decay changes caused by spatial and habitat variation than other indices at larger scales,whereas AW-D nn and D nn better reflected these changes at small scales. | FENG Gang ZHANG JinLong PEI NanCai RAO MiDe MI XiangCheng REN HaiBao MA KePing | 2012 | Chinese Science Bulletin2012,57,6: | 9 |
| 10 | Extracellular matrix from human umbilical cordderived mesenchymal stem cells as a scaffold for peripheral nerve regeneration显示文摘The extracellular matrix,which includes collagens,laminin,or fibronectin,plays an important role in peripheral nerve regeneration.Recently,a Schwann cell-derived extracellular matrix with classical biomaterial was used to mimic the neural niche.However,extensive clinical use of Schwann cells remains limited because of the limited origin,loss of an autologous nerve,and extended in vitro culture times.In the present study,human umbilical cord-derived mesenchymal stem cells(h UCMSCs),which are easily accessible and more proliferative than Schwann cells,were used to prepare an extracellular matrix.We identified the morphology and function of h UCMSCs and investigated their effect on peripheral nerve regeneration.Compared with a non-coated dish tissue culture,the h UCMSC-derived extracellular matrix enhanced Schwann cell proliferation,upregulated gene and protein expression levels of brain-derived neurotrophic factor,glial cell-derived neurotrophic factor,and vascular endothelial growth factor in Schwann cells,and enhanced neurite outgrowth from dorsal root ganglion neurons.These findings suggest that the h UCMSC-derived extracellular matrix promotes peripheral nerve repair and can be used as a basis for the rational design of engineered neural niches. | Bo Xiao Feng Rao Zhi-yuan Guo Xun Sun Yi-guo Wang Shu-yun Liu Ai-yuan Wang Quan-yi Guo Hao-ye Meng Qing Zhao Jiang Peng Yu Wang Shi-bi Lu | 2016 | Neural Regeneration Research2016,11,7: | 8 |
| 11 | Crystal structure of SARS-CoV-2 main protease in complex with protease inhibitor PF-07321332显示文摘Dear Editor,Since December 2019,the pandemic of coronavirus disease 2019(COVID-19)has taken a heavy toll on global health,creating an urgent need to develop effective strategies for prevention and treatment.The etiological agent,known as severe acute respiratory syndrome coronavirus 2(SARSCoV-2),has infected nearly 229.2 million people worldwide with more than 4.7 million deaths as of September 15,2021.Older age and preexisting health conditions are associated with worse clinical prognosis including higher mortality rates(Zhou et al.,2020).The global race to combat this pandemic has led to rapid deployment of numerous effective vaccines against SARS-CoV-2(Tregoning et al.,2021).However,the emergence of viral variants,including the Delta variant(B.1.617.2),compromised vaccine effectiveness with resurgence of SARS-CoV-2 infection among highly vaccinated population(Keehner et al.,2021).Therefore,development of therapeutics against the more conserved viral targets would be essential to contain the spread of COVID-19 and reduce mortality. | Yao Zhao Chao Fang Qi Zhang Ruxue Zhang Xiangbo Zhao Yinkai Duan Haofeng Wang Yan Zhu Lu Feng Jinyi Zhao Maolin Shao Xiuna Yang Leike Zhang Chao Peng Kailin Yang Dawei Ma Zihe Rao Haitao Yang | 2022 | Protein & Cell2022,13,9: | 6 |
| 12 | Triptolide suppresses pancreatic cancer cell proliferation by inhibiting hedgehog signaling pathway activity显示文摘Dear Editor,Pancreatic cancer (PCa) is a high-grade gastrointestinal malignancy more commonly occurring in elderly populations with lower than 5% overall 5-year survival rate (Hidalgo, 2010). PCa responds poorly to most chemotherapeutic agents, and therefore it is imperative to develop novel therapeutic agents that have anti-cancer activities against PCa. | Juanjuan Feng Mingjin Rao Man Wang Lin Liang Zhi Chen Xiufeng Pang Weiqiang Lu Zhenliang Sun | 2019 | Science China(Life Sciences)2019,62,10: | 6 |
| 13 | Experimental research on grouser traction of deep-sea mining machine显示文摘The traction characteristics of the grouser, cutting the simulative soil of deepsea sediment, with different tooth widths, tooth heights, and ground pressures are studied with traction characteristic test apparatus. A traction-displacement model is obtained by combining the analysis of the cutting mechanism. The results show that the tractiondisplacement curves of grousers with different tooth widths, tooth heights, and ground pressures have the same changing trend, which matches the Wong traction model. Their sensitivity coefficient and shear modulus are slightly fluctuated. Therefore, the average values can be used as the traction model parameters. The maximum traction of the grouser with a two-side edge and a 10 mm tooth width increment changing with the tooth height and ground pressure can be determined according to the grousers with different tooth widths. By combining the traction model parameters, the traction-displacement curve of the grouser with a certain group values of tooth width, tooth height, and ground pressure can be predicted. Therefore, the slip of the mining machine can be prevented to improve the mining efficiency. | Wenbo MA Qiuhua RAO Kang FENG Feng XU | 2015 | Applied Mathematics and Mechanics(English Edition)2015,36,9: | 5 |

| 16 | Hepatic perivascular epithelioid cell tumor in three patients显示文摘Perivascular epithelioid cell tumor(PEComa) is a rare, soft tissue tumor that can occur in various locations. The present report included three patients(one male and two females; age range, 25-51 years) with hepatic PEComas. The collected data included the clinical manifestations, diagnosis, management, treatment, and prognosis. Since it is difficult to diagnose hepatic PEComas by imaging, the patients were diagnosed by tumor tissue examination such as immunohistochemistry, which was positive for HMB-45, Melan-A, and SMA on all slides. The tumor was composed of diverse tissues including smooth muscle, adipose tissue, and thick-walled blood vessels. During the follow-up period, one of the tumors was malignant(double-positive for CD34 and Ki-67) and recurred 3 months after surgery. In addition, malignant hepatic PEComas were reviewed in the literature, indicating that the majority of hepatic PEComas are benign, but few hepatic PEComas exhibit malignant behaviors in older female patients(>50 years of age) with abdominal discomfort and pain, larger tumor size(>10 cm), or positive staining for CD34 and Ki-67. In conclusion, there is no effective method to diagnose PEComas. Currently, the diagnosis of PEComas depends on immunohistochemical staining. Tumor resection and close follow-up are the principal methods for the management of PEComas. | Bao-Bin Hao Jian-Hua Rao Ye Fan Chuang-Yong Zhang Xin-Zheng Dai Xiao Li Yan Leng Feng Zhang | 2016 | Hepatobiliary & Pancreatic Diseases International2016,15,6: | 4 |

| 18 | New insights into store-independent Ca^(2+) entry: secretory pathway calcium ATPase 2 in normal physiology and cancer显示文摘Recent studies in secretory pathway calcium ATPases (SPCA) revealed novel functions of SPCA2 in interacting with store-operated Ca2+ channel Orai1 and inducing Ca2+ influx at the cell surface. Importantly, SPCA2-mediated Ca2+ signaling is uncoupled from its conventional role of Ca2+ -ATPase and independent of store-operated Ca2+ signaling pathway. SPCA2-induced store-independent Ca2+ entry (SICE) plays essential roles in many important physiological processes, while unbalanced SICE leads to enhanced cell proliferation and tumorigenesis. Finally, we have summarized the clinical implication of SICE in oral cancer prognosis and treatment. Inhibition of SICE may be a new target for the development of cancer therapeutics. | Ming-Ye Feng Rajini Rao | 2013 | International Journal of Oral Science2013,5,2: | 3 |
| 19 | Building Information Modeling-Based Secondary Development System for 3D Modeling of Underground Pipelines显示文摘Underground pipeline networks constitute a major component of urban infrastructure,and thus,it is imperative to have an efficient mechanism to manage them.This study introduces a secondary development system to efficiently model underground pipeline networks,using the building information modeling(BIM)-based software Revit.The system comprises separate pipe point and tubulation models.Using a Revit application programming interface(API),the spatial position and attribute data of the pipe points are extracted from a pipeline database,and the corresponding tubulation data are extracted from a tubulation database.Using the Family class in Revit API,the cluster in the self-built library of pipe point is inserted into the spatial location and the attribute data is added;in the same way,all pipeline instances in the pipeline system are created.The extension and localization of the model accelerated the modeling speed.The system was then used in a real construction project.The expansion of the model database and rapid modeling made the application of BIM technology in three-dimensional visualization of underground pipeline networks more convenient.Furthermore,it has applications in pipeline engineering construction and management. | Jun Chen Rao Hu Xianfeng Guo Feng Wu | 2020 | Computer Modeling in Engineering & Sciences2020,,5: | 2 |
| 20 | Structures of the portal vertex reveal essential protein-protein interactions for Herpesvirus assembly and maturation显示文摘Dear Editor,Herpesviridae is a large family of double-stranded DNA(dsDNA)viruses that cause a variety of human diseases ranging from cold sores and chicken pox to congenital defects,blindness and cancer(Chayavichitsilp et al.,2009;Wang et al.,2018).In the past 70 years,substantial advances in our knowledge of the molecular biology of herpesviruses have led to insights into disease pathogenesis and management.However,the mechanism for capsid assembly that requires the ordered packing of about 4,000 protein subunits into the hexons,pentons and triplexes remains elusive.It is still a puzzle how initially identical subunits adopt both hexameric and pentameric conformations in the capsid and select the correct locations needed to form closed shells of the proper size.Biochemical and genetic studies have shown that the portal is involved in initiation of capsid assembly(Newcomb et al.,2005)and functions akin to a DNA-sensor coupling genome-packaging achieved by a genome-packaging machinery-“terminase complex”(Chen et al.,2020;Yunxiang Yang,2020)with icosahedral capsid maturation(Lokareddy et al.,2017).Structural investigations of the herpesvirus portal have proven challenging due to the small size of this dodecamer,which accounts for less than 1%of the total mass of the capsid protein layer and the technical difficulties involved in resolving non-icosahedral components of such large icosahedral viruses(diameter is∼1,250Å).Efforts of many investigators over two decades have made to reconstruct the cryo-electron microscopy(cryo-EM)structure of herpesvirus portal vertex and more recently near-atomic structures of two herpesvirus(herpes simplex virus type 1(HSV-1)and Kaposi’s sarcoma-associated herpesvirus(KSHV))portal vertices were reported(McElwee et al.,2018;Gong et al.,2019;Liu et al.,2019). | Nan Wang Wenyuan Chen Ling Zhu Dongjie Zhu Rui Feng Jialing Wang Bin Zhu Xinzheng Zhang Xiaoqing Chen Xianjie Liu Runbin Yan Dongyao Ni Grace Guoying Zhou Hongrong Liu Zihe Rao Xiangxi Wang | 2020 | Protein & Cell2020,11,5: | 2 |
