| 1 | 16 × 16 silicon Mach–Zehnder interferometer switch actuated with waveguide microheaters显示文摘We experimentally demonstrate a 16 × 16 reconfigurably nonblocking optical switch fabric using a Benes architecture. The switch fabric consists of 56 2 × 2 Mach–Zehnder interferometer based elementary switches, with each integrated with a pair of waveguide microheaters. The average on-chip insertion loss is ~5.2 dB for both of the 'all-cross' and the 'all-bar' states, with a loss variation of 1 dB over all routing paths. The cross talk for all switching states is better than -30 d B. The switching time of the switch element is about 22 μs. The switching functionality is verified by transmission of a 40 Gb∕s quadrature phase-shift keying optical signal. | Shuoyi Zhao Liangjun Lu Linjie Zhou Dong Li Zhanzhi Guo Jianping Chen | 2016 | Photonics Research2016,4,5: | 7 |
| 2 | Human CMTM2/CKLFSF2 enhances the ligand-induced transactivation of the androgen receptor显示文摘CKLF (chemokine-like factor)-like MARVEL (MAL and related proteins for vesicle trafficking and mem-brane link domain) transmembrane domain containing (CMTM) is a novel gene family. One member of this family, CMTM2, also named chemokine-like factor superfamily 2 (CKLFSF2), is expressed highly in the testis and moderately in the prostate, marrow and peripheral blood cells. However, the function of human CMTM2 remains unknown. Here, we found that CMTM2 was upregulated in 5α-dihydrotestos- terone (DHT)-treated LNCaP cells. We investigated the relationship between CMTM2 and the androgen receptor. Our results showed that CMTM2 enhanced DHT-mediated androgen receptor (AR) transacti-vation and the expression of prostate specific antigen (PSA). We also observed that CMTM2 enhanced the AR protein level, which was reversed by silencing endogenous CMTM2 expression, which sug-gested that CMTM2 might play an important role in maintaining the AR protein level. We also found that CMTM2 suppressed Akt activation. A previous study showed that Akt could phosphorylate AR at Ser210 and Ser790 and lead to AR ubiquitylation and degradation as well as suppression of AR activity. Taken together, suppressing Akt activation and increasing the AR protein level might be one of the mechanisms for the CMTM2-mediated enhancement of AR transactivation. | LIU DaZhen YIN CaiHua ZHANG YingMei TIAN LinJie LI Ting LI Dan MA DaLong GUO YingLu WANG Ying | 2009 | Chinese Science Bulletin2009,54,6: | 7 |
| 3 | Change of Visual Acuity and Related Factors in Idiopathic Optic Neuritis显示文摘Purpose : To study the change of visual acuity and related factors in idiopathic optic neuritis.
Methods: Retrospectively studying 136 cases (210 eyes) of idiopathic optic neuritis hospitalized in our department during last 5 years. The data was analyzed with the methods of multivariate stepwise regression analysis by SPSS statistic package.
Results: The final visual acuity was very strongly related positively to the initial visual acuity at the time point of starting treatment and negatively to the time span beginning the treatment to the time showing improvement, age of patient and the duration from onset of the disorder to the time point of treatment beginning.
Conclusions: Promptly right treatment can significantly change the natural course and the final vision of optic neuritis. Severe visual loss, old age, longer time without right therapy and slow improvement after the treatment may indicate an unfavorable final visual recovery. The different dosages of steroid applied in this study was not significant in view of the final visual acuity.

| 4 | RNA Methylome Reveals the m^(6)A-mediated Regulation of Flavor Metabolites in Tea Leaves under Solar-withering显示文摘The epitranscriptomic mark N6-methyladenosine(m^(6)A),which is the predominant internal modification in RNA,is important for plant responses to diverse stresses.Multiple environmental stresses caused by the tea-withering process can greatly influence the accumulation of specialized metabolites and the formation of tea flavor.However,the effects of the m^(6)A-mediated regulatory mechanism on flavor-related metabolic pathways in tea leaves remain relatively uncharacterized.We performed an integrated RNA methylome and transcriptome analysis to explore the m^(6)Amediated regulatory mechanism and its effects on flavonoid and terpenoid metabolism in tea(Camellia sinensis)leaves under solar-withering conditions.Dynamic changes in global m^(6)A level in tea leaves were mainly controlled by two m^(6)A erasers(CsALKBH4A and CsALKBH4B)during solar-withering treatments.Differentially methylated peak-associated genes following solarwithering treatments with different shading rates were assigned to terpenoid biosynthesis and spliceosome pathways.Further analyses indicated that CsALKBH4-driven RNA demethylation can directly affect the accumulation of volatile terpenoids by mediating the stability and abundance of terpenoid biosynthesis-related transcripts and also indirectly influence the flavonoid,catechin,and theaflavin contents by triggering alternative splicing-mediated regulation.Our findings revealed a novel layer of epitranscriptomic gene regulation in tea flavor-related metabolic pathways and established a link between the m^(6)A-mediated regulatory mechanism and the formation of tea flavor under solar-withering conditions. | Chen Zhu Shuting Zhang Chengzhe Zhou Caiyun Tian Biying Shi Kai Xu Linjie Huang Yun Sun Yuling Lin Zhongxiong Lai Yuqiong Guo | 2023 | Genomics, Proteomics & Bioinformatics2023,21,4: | 2 |
| 5 | Tea Polyphenols Reducing Lipopolysaccharide-induced Inflammatory Responses in RAW264.7 Macrophages via NF-κB Pathway显示文摘The anti-inflammatory activity of tea polyphenols(TPs)in RAW264.7 macrophages stimulated by lipopolysaccharide(LPS)was investigated in this paper.RAW264.7 macrophages were treated with different concentrations of TP(0,12.5,25,50,100,and 200μg/mL)and then stimulated by LPS.Another blank control group was set up.The expression of pro-inflammatory cytokines associated with the nuclear factor-kappa B(NF-κB)signaling pathway was investigated before and after TP treatment.Pretreatment of RAW264.7 cells with TP decreased the expression of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and interleukin 1 beta(IL-1β)pro-inflammatory cytokines.In addition,TP inhibited the phosphorylation of p65 and IκB by blocking the phosphorylation and the degradation of NF-κB inhibitor protein.In conclusion,TP exerts anti-inflammatory effects by regulating the release of inflammatory mediators via the NF-κB signaling pathway. | SU Siyi LI Xiaoyu GUO Xu ZHOU Ruiming LI Manman MING Pengfei HUANG Yingying Sajid Ur RAHMAN DING Hongyan FENG Shibin LI Jinchun WANG Xichun LI Yu WU linjie | 2019 | Chemical Research in Chinese Universities2019,35,6: | 1 |
| 6 | Study on sulfur deposition damage model of fractured gas reservoirs with high-content H_(2)S显示文摘Due to extreme poison,strong corrosion,and complex precipitation and deposition of H_(2)S in the reservoir,it is very difficult and risky to investigate and explore drilling,completion,production and gas transportation.In the course of production of fractured gas reservoir with high H_(2)S content,formation pressure falls continually,which lead to decline of solubility of sulfur particles in gas phase.Sulfur particles which dissolve in gas phase originally in the formation should precipitate from gas phase after running up to saturation state and deposit at pore space and throat,sequentially resulting in formation porosity and permeability reduction.At present,the researches of sulfur deposition are mainly focused on the conventional gas reservoirs and sulfur deposition in the near wellbore region is generally estimated using Roberts'model.However,most of the gas reservoirs with high-content H2S are fractured gas reservoirs,classical damage model is no longer applicable to fractured gas reservoirs with high H2S content.In the present study,a sulfur deposition damage model is established.The refined model,based on non-Darcy flow,takes into consideration the effects of sulfur deposition,variation in gas properties and fracture.In addition,the effect of gas well production rate on formation permeability is also studied.The results show that formation permeability decreases with fracture aperture and gas well production rate increasing.The bigger gas well production rate is,the quicker sulfur precipitates.The sulfur deposition of fractured gas reservoir with high-content H_(2)S is mainly in the near wellbore zone,and the fracture aperture has a significant impact on the formation permeability in the near wellbore zone. | Linji He Xiao Guo | 2017 | Petroleum2017,3,3: | 1 |
| 7 | Continuous-variable quantum key distribution with on-chip light sources显示文摘Integrated quantum key distribution(QKD)systems based on photonic chips have high scalability and stability,and are promising for further construction of global quantum communications networks.On-chip quantum light sources are a critical component of a fully integrated QKD system;especially a continuous-variable QKD(CVQKD)system based on coherent detection,which has extremely high requirements for the light sources.Here,for what we believe is the first time,we designed and fabricated two on-chip tunable lasers for CV-QKD,and demonstrated a high-performance system based on these sources.Because of the high output power,fine tunability,and narrow linewidth,the involved on-chip lasers guarantee the accurate shot-noise-limited detection of quantum signals,center wavelength alignment of nonhomologous lasers,and suppression of untrusted excess noise.The system’s secret key rate can reach 0.75 Mb/s at a 50 km fiber distance,and the secure transmission distance can exceed 100 km.Our results mark a breakthrough toward building a fully integrated CV-QKD,and pave the way for a reliable and efficient terrestrial quantum-secure metropolitan area network. | LANG LI TAO WANG XINHANG LI PENG HUANG YUYAO GUO LIANGJUN LU LINJIE ZHOU GUIHUA ZENG | 2023 | Photonics Research2023,11,4: | 0 |
| 8 | The chromosome-scale genome assembly of Jasminum sambac var. unifoliatum provides insights into the formation of floral fragrance显示文摘Jasmine [Jasminum sambac(L.) Ait.], a tropical and subtropical plant emits a sweet, heady fragrance during flower opening. However, the molecular mechanisms underlying this phenomenon remain largely unknown. In the present study, integrated Illumina sequencing, Pacbio sequencing, and high-throughput chromatin conformation capture(Hi-C) scaffolding was used to generate a 495.60 Mb genome assembly of J.sambac var. unifoliatum cultivar ‘Fuzhou Single-petal’(JSU-FSP), with contig N50 of 16.88 Mb;96.23% of the assembly was assigned to 13 pseudochromosomes. The genome harbors 30 989 protein-coding genes, and 49.47% of the assembled sequences are repetitive sequences. The analysis of duplication modes showed that 51% of genes were duplicated through dispersed duplication, and expanded gene families are mainly involved in photosynthesis, which may be responsible for the light-loving characteristic specific to jasmine. Transcriptome analysis revealed that at least 35 structural genes involved in the biosynthesis of volatile terpenes(VTs), volatile phenylpropanoid/benzenoids(VPBs),fatty acid-derived volatiles(FADVs), and indole were highly expressed in the flower-opening stage, both preharvest and postharvest, and are proposed to be important in endowing flower aroma. Additionally, at least 28 heat shock protein(HSP) and 11 β-glucosidase(BGLU) genes may be involved in the formation of floral fragrance. These findings provide insights into the formation of the floral fragrance of jasmine and will promote germplasm utilization for breeding improved jasmine varieties. | Chengzhe Zhou Chen Zhu Caiyun Tian Siyi Xie Kai Xu Linjie Huang Shengjing Wen Cheng Zhang Zhongxiong Lai Yuling Lin Yuqiong Guo | 2023 | Horticultural Plant Journal2023,9,6: | 0 |

| 10 | Identifying a confused cell identity for esophageal squamous cell carcinoma显示文摘The cell identity of malignant cells and how they acquire it are fundamental for our understanding of cancer.Here,we report that esophageal squamous cell carcinoma(ESCC)cells display molecular features equally similar but distinct to all three types of normal esophageal epithelial cells,which we term as confused cell identity(CCI).CCI is an independent prognostic marker associated with poor prognosis in ESCC.Further,we identify tropomyosin 4(TPM4)as a critical CCI gene that promotes the aggressiveness of ESCC in vitro and in vivo.And TPM4 creates CCI through activating the Jak/STAT-SOX2 pathway.Thus,our study suggests an unrecognized feature of ESCC cells,which might be of value for clinic prognosis and potential interference. | Xiangyu Pan Jian Wang Linjie Guo Feifei Na Jiajia Du Xuelan Chen Ailing Zhong Lei Zhao Lu Zhang Mengsha Zhang Xudong Wan Manli Wang Hongyu Liu Siqi Dai Ping Tan Jingyao Chen Yu Liu Bing Hu Chong Chen | 2022 | Signal Transduction and Targeted Therapy2022,7,5: | 0 |
