Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

Oncology research 2025年第1期33卷 171-184页

作者： Gengyun Sun Yiping Zheng Jianfeng Cai jie Gao Lie Dong Xiangbin Zhang Yinghui Huang Department of Respiratory and Critical Care Medicine The First Affiliated Hospital of Anhui Medical University Hefei 230022 China. Department of Respiratory and Critical Care Medicine Nanping First Hospital Affiliated to Fujian Medical University Nanping 353006 China.

Background:Long noncoding RNA, LINC01106 exhibits high expression in lung adenocarcinoma (LUAD) tumor tissues, but its functional role and regulatory mechanism in LUAD cells remain unclear.Methods:LINC01106 expression was analyzed in LUAD tissues and its functional impact on LUAD cells was assessed. LUAD cells were silenced with sh-LINC01106 and injected into nude mice to investigate tumor growth. The downstream transcription factors and molecular mechanism were determined using the Human transcription factor database (TFDB) database and Gene Expression Profiling Interactive Analysis (GEPIA) database. Additionally, the impact of linc01106 on autophagy was analyzed by determining the expression of autophagy-related genes (ATGs) in LUAD cells.Results:Our results showed that LINC01106 exhibited upregulation in both LUAD tissues and cell lines. The silencing of LINC01106 demonstrated a suppressive effect on tumorigenesis in a xenograft mouse model of LUAD. Additionally, LINC01106 was found to recruit TATA-binding protein-associated factor 15 (TAF15), an RNA-binding protein, thereby enhancing the mRNA stability of TEA domain transcription factor 4 (TEAD4). In turn, TEAD4 served as a transcription factor that bound to the LINC01106 promoter and regulated its expression. Further assays indicated that LINC01106 promoted autophagy in LUAD cells by upregulating the expression of autophagy-related genes (ATGs). The silencing of LINC01106 in LUAD cells inhibited autophagy, and cell proliferation, and promoted apoptosis, which all were effectively reversed by ATG5 overexpression.Conclusions:Overall, LINC01106, transcriptionally activated by TEAD4, interacts with TAF15 to promote the stability of TEAD4 and upregulates the expression of ATGs, promoting malignancy of LUAD cells.

麦角硫因是食用菌中的天然活性物质,具有抗氧化和螯合金属等作用。为进一步提高生物发酵法生产麦角硫因的产量,本研究利用紫外诱变(UV)、甲基磺酸乙酯诱变(EMS)、航天诱变(SFM)技术对榆黄菇菌株进行诱变处理,以菌丝生长速度和液态发酵麦角硫因产量为评价指标,选育高产麦角硫因榆黄菇菌株。结果表明,UV诱变、EMS诱变和SFM诱变处理后分别得到了46、40、48株突变菌株,其中UV诱变产麦角硫因菌株的正突变率最高,为43.48%。UV诱变、EMS诱变和SFM诱变分别得到8、3、1株液态发酵麦角硫因产量极显著高于出发菌株的榆黄菇菌株(P<0.01)。在12株高产麦角硫因诱变菌株中,UV-30株产量最高,是出发菌株的2.16倍,UV-13的生长速度最快,是出发菌株的1.02倍。遗传距离分析表明SFM诱变菌株变异程度高于UV诱变菌株,且两者变异程度均高于EMS诱变菌株。本研究结果为麦角硫因生物合成途径基础研究提供了材料,同时为榆黄菇高产麦角硫因菌株诱变选育研究提供了参考依据。

Micromechanical Analysis of In-Plane Constraint Effect on Local Fracture Behavior of Cracks in the Weakest Locations of Dissimilar Metal Welded Joint

引用

Acta Metallurgica Sinica(English Letters) 2017年第9期30卷 840-850页

作者： jie Yang School of Energy and Power Engineering University ofShanghai for Science and TechnologyShanghai 200093China

In this work, a set of GTN （Gurson-Tvergaard-Needleman） parameters of the Alloy52M dissimilar metal welded joint （DMWJ） have been calibrated, and a micromechanical analysis of in-plane constraint effects on the local fracture behavior of two cracks, which located in the weakest regions of the DMWJ, has been investigated by the local approach based on the GTN damage model. The results show that the partition of the material and the variation of the q2 parameter make the J-resistance curves obtained by numerical simulations close to the experimental values. The numerical J-resistance curves and crack growth paths are consistent with the experiment results, which show that the GTN damage model can incorporate the in-plane constraint effect. Furthermore, after the stress, strain and damage fields at the crack tip during the crack propagation process have been calculated, and the change of the J-resistance curves, crack growth paths and fracture mechanism with in-plane constraint have been analyzed.

A general framework for computing maximal contractions

引用

Frontiers of Computer Science 2013年第1期7卷 83-94页

作者： jie LUO State Key Laboratory of Software Development Environment School of Computer Science and Engineering Beihang University Beijing 100191 China

This paper investigates the problem of computing all maximal contractions of a given formula set F with re- spect to a consistent set A of atomic formulas and negations of atomic formulas. We first give a constructive definition of minimal inconsistent subsets and propose an algorithmic framework for computing all minimal inconsistent subsets of any given formula set. Then we present an algorithm to com- pute all maximal contractions from minimal inconsistent sub- sets. Based on the algorithmic framework and the algorithm, we propose a general framework for computing all maximal contractions. The computability of the minimal inconsistent subset and maximal contraction problems are discussed. Fi- nally, we demonstrate the ability of this framework by apply- ing it to the first-order language without variables and design an algorithm for the computation of all maximal contractions.

Preparation, characterization and application of thiosemicarbazide grafted multiwalled carbon nanotubes for solid-phase extraction of Cd(II),Cu(II) and Pb(II) in environmental samples

引用

Journal of Environmental Sciences 2013年第11期25卷 2331-2337页

作者： jie Zhang College of Environmental Science and Engineering Tongji University

Thiosemicarbazide-grafted multi-walled carbon nanotubes were prepared and employed to investigate the pre-concentration of Cd（Ⅱ）, Cu（Ⅱ） and Pb（Ⅱ） from aqueous solution prior to their determination by ICP-OES. The resulting material was characterized by FT-IR, TGA and SEM. Various factors influencing the separation and pre-concentration were investigated. The enrichment factor typically is 60. Under optimized experimental conditions, the maximum adsorption capacities of Cd（Ⅱ）, Cu（Ⅱ） and Pb（Ⅱ） were found to be 1.98, 10.94, 3.69 mg/g, and the relative standard deviations are 〈 3.5% （n = 6）. The new adsorbent shows superior reusability and stability. The procedure was successfully applied to the determination of trace quantities of Cd（Ⅱ）, Cu（Ⅱ） and Pb（Ⅱ） in water samples.

circT P63-N suppresses the proliferation and metastasis of nasopharyngeal carcinoma via engaging with HSP90AB1 to modulate the YAP1/Hippo signaling pathway

Science China Life Sciences 2025年

Circular RNAs(circRNAs) play pivotal roles in the development and progression of various diseases, including malignant tumors. However,the biological functions and the underlying mechanisms of many circRNAs remain elusive. In this study, we identified a novel circRNA,circTP63-N, generated through the splicing of exons 2–4 of the TP63 gene in nasopharyngeal carcinoma(NPC). circTP63-N was found to be downregulated in clinical samples of NPC. Both in vitro and in vivo experiments unequivocally demonstrated that circTP63-N inhibits the proliferation and metastasis of NPC cells. Further investigations revealed that circTP63-N interacted with the HSP90AB1 protein, leading to the recruitment of LATS/YAP1 proteins. This, in turn, induced phosphorylation and ubiquitination-dependent degradation of YAP1, resulting in reduced nuclear translocation of YAP1 and inhibition of the transcriptional activation of downstream oncogenic genes, including INHBA, MMP3, and CCNE2. Our findings highlight the identification of circTP63-N, a novel circRNA encoded by an important tumor-relevant gene TP63 and elucidate its molecular mechanism as a tumor suppressor in NPC. These insights offer novel potential molecular markers and therapeutic targets for the clinical diagnosis and treatment of NPC.
