| 1 | Advances in biomaterials and regenerative medicine for primary ovarian insufficiency therapy显示文摘Primary ovarian insufficiency(POI)is an ovarian dysfunction that affects more than 1%of women and is characterized by hormone imbalances that afflict women before the age of 40.The typical perimenopausal symptoms result from abnormal levels of sex hormones,especially estrogen.The most prevalent treatment is hormone replacement therapy(HRT),which can relieve symptoms and improve quality of life.However,HRT cannot restore ovarian functions,including secretion,ovulation,and fertility.Recently,as part of a developing field of regenerative medicine,stem cell therapy has been proposed for the treatment of POI.Thus,we recapitulate the literature focusing on the use of stem cells and biomaterials for POI treatment,and sum up the underlying mechanisms of action.A thorough understanding of the work already done can aid in the development of guidelines for future translational applications and clinical trials that aim to cure POI by using regenerative medicine and biomedical engineering strategies. | Sichen Zhang Dashuai Zhu Xuan Mei Zhenhua Li Junlang Li Mengjie Xie Halle Jiang Williams Lutz Shaowei Wang Ke Cheng | 2021 | Bioactive Materials2021，6，7： | 9 |

| 3 | Integration of solid phase extraction with HILIC-MS/MS for analysis of free amino acids in source water显示文摘Amino acids(AAs) are prevalent in source water, particularly during spring run-off. Monitoring of amino acids in source water is desirable for water treatment plants(WTP) to indicate changes in source water quality. The objective of this study was to establish analytical procedures for reliable monitoring of amino acids in source water. Therefore, we examined two different methods, large volume inject(LVI) and solid phase extraction(SPE), for sample preparation prior to HILIC-MS/MS. The LVI-HILIC-MS/MS method can provide fast and sensitive detection for clean samples, but suffers from matrix effects, resulting in irreproducible separation and shortening column lifetime. We have demonstrated that SPE was necessary prior to HILIC-MS/MS to achieve reproducible and reliable quantification of AAs in source water. A natural heterocyclic amine 1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid(MTCCA) was also included in the method to indicate changes in other natural nitrogenous compounds in source water. The SPE-HILIC-MS/MS method was able to achieve limits of detection from 2.6-3400 ng/L for the amino acids and MTCCA with RSDs( n = 3) of 1.1%-4.8%. As well, retention times(RT) of the analytes were reproducible with variation less than 0.01 min( n = 3) through the entire project. We further applied the SPE-HILICMS/MS method to determine AAs in authentic source water samples collected from two drinking water treatment plants(WTPs) during the 2021 spring run-off season. The results support that the SPE-HILIC-MS/MS method does not require derivatization and can provide reliable, accurate, and robust analysis of AAs and MTCCA in source water, supporting future monitoring of source water quality. | Junlang Qiu Caley Craven Nicholas Wawryk Kristin Carroll Xing-Fang Li | 2022 | Journal of Environmental Sciences2022，34，7： | 1 |
| 4 | A trifunctional contraceptive gel enhances the safety and quality of sexual intercourse显示文摘Current contraceptive methods come with a number of drawbacks,including low efficacy,in the case of commercial contraceptive gels,and a reduction in the quality of sexual intercourse,in the case of condoms.Adding pharmacologically-active agents to contraceptive gels holds the potential to improve sexual experience,and hardbor safety and hygiene.In this study,we fabricated a carbomer-based contraceptive gel consisting of three agents:tenofovir,gossypol acetate,and nitroglycerin(TGN),with pH adjusted to 4.5(to be compatible with the vagina).In vitro,the gossypol component of the contraceptive gel proved to be an effective spermicide.When the concentration of gossypol acetate was 10 mg/ml,the spermicidal ability reached 100%after 30 s.In addition,tenofovir in the gel significantly inhibited lentiviral transfection efficiency in cell-containing media.In 6 pairs of rats,the gel successfully prevented all females from conceiving after successful mating.Moreover,increased sexual frequency and enhanced erection,which were promoted by the nitroglycerin in the components,were observed in male rats that had the gel applied to their penises.This novel TGN contraceptive gel yielded a higher contraceptive success rate than that of the commercial contraceptive gel(Contragel®).In addition,it has the added benefits to prevent sexually transmitted diseases and improve male libido and erectile function during sexual intercourse.Combining three FDA-approved and marketed agents together,our trifunctional TGN gel has a great potential for further translation and commercialization. | Mengjie Xie Junlang Li Sichen Zhang Dashuai Zhu Xuan Mei Zhenzhen Wang Xiao Cheng Zhenhua Li Shaowei Wang Ke Cheng | 2021 | Bioactive Materials2021，6，6： | 1 |

| 6 | PtCoNi ternary intermetallic compounds anchored on Co,Ni and N co-doped mesoporous carbon:Synergetic effect between PtCoNi nanoparticles and doped mesoporous carbon promotes the catalytic activity显示文摘Highly active and robust electrocatalysts are desired for proton exchange membrane fuel cells.Pt-based intermetallic compounds(IMCs) have been recognized as one of the most promising low-platinum catalysts for fuel cells(FCs).Herein,we report a high-performance IMCs by anchoring ordered PtCoNi ternary nanoparticles on the N,Co and Ni co-doped dodecahedral mesoporous carbon(DMC).While the introduced Co and Ni participate in the formation of PtCoNi IMCs,some of them are doped in the mesoporous carbon and coordinated by N to form Co-N_(y)/Ni-N_(z)dual active centers,which further enhances the electrocatalytic activity towards oxygen reduction reaction.Moreover,the addition of Ni results in a negative shift of the d-band center of Pt as compared to the Pt/DMC and Pt_(3)Co/DMC,making it easier to adsorb oxygen on the surface.As expected,our optimal sample Pt_(3)Co_(0.7)Ni_(0.3)/DMC exhibits excellent performance with mass activity and specific activity of 1.32 A mgPt-1and 1.98 mA cm^(-2)at 0.9 V,which are 7.33and 6.19 times that of commercial Pt/C,respectively.The Pt_(3)Co_(0.7)Ni_(0.3)/DMC also reveals much better cathodic performance in an H2-air single fuel cell than commercial Pt/C catalyst with a power density of0.802 W cm^(-2).This work provides critical sights into constructing efficient catalysts by ternary intermetallic strategy and synergetic effect between active components and support. | Chaozhong Li Weiyue Zhao Xueyi Lu Zhangsen Chen Bing Han Xiaorong Zhang Jiaxiang Chen Yijia Shao Junlang Huo Yuexiang Zhu Yonghong Deng Shuhui Sun Shijun Liao | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
| 7 | Synergistic cytotoxicity of binary combinations of inorganic and organic disinfection byproducts assessed by real-time cell analysis显示文摘Chlorine, chlorine dioxide, and ozone are widely used as disinfectants in drinking water treatments. However, the combined use of different disinfectants can result in the formation of various organic and inorganic disinfection byproducts(DBPs). The toxic interactions, including synergism, addition, and antagonism, among the complex DBPs are still unclear. In this study, we established and verified a real-time cell analysis(RTCA) method for cytotoxicity measurement on Chinese hamster ovary(CHO) cell. Using this convenient and accurate method, we assessed the cytotoxicity of a series of binary combinations consisting of one of the 3 inorganic DBPs(chlorite, chlorate, and bromate) and one of the 32 regulated and emerging organic DBPs. The combination index(CI) of each combination was calculated and evaluated by isobolographic analysis to reflect the toxic interactions. The results confirmed the synergistic effect on cytotoxicity in the binary combinations consisting of chlorite and one of the 5 organic DBPs(2 iodinated DBPs(I-DBPs) and 3 brominated DBPs(Br-DBPs)), chlorate and one of the 4 organic DBPs(3 aromatic DBPs and dibromoacetonitrile), and bromate and one of the 3 organic DBPs(2 I-DBPs and dibromoacetic acid). The possible synergism mechanism of organic DBPs on the inorganic ones may be attributed to the influence of organic DBPs on cell membrane and cell antioxidant system. This study revealed the toxic interactions among organic and inorganic DBPs, and emphasized the latent adverse outcomes in the combined use of different disinfectants. | Mengge Fan Longfei Shu Xinran Zhang Miao Yu Yongting Du Junlang Qiu Xin Yang | 2022 | Journal of Environmental Sciences2022，34，7： | 0 |
| 8 | Remediation of preservative ethylparaben in water using natural sphalerite:Kinetics and mechanisms显示文摘As a typical class of emerging organic contaminants(EOCs), the environmental transformation and abatement of preservative parabens have raised certain environmental concerns. However, the remediation of parabens-contaminated water using natural matrixes(such as, naturally abundant minerals) is not reported extensively in literature. In this study, the transformation kinetics and the mechanism of ethylparaben using natural sphalerite(NS) were investigated. The results show that around 63% of ethylparaben could be absorbed onto NS within 38 hr, whereas the maximum adsorption capacity was 0.45 mg/g under room temperature. High temperature could improve the adsorption performance of ethylparaben using NS. In particular, for the temperature of 313 K, the adsorption turned spontaneous. The well-fitted adsorption kinetics indicated that both the surface adsorption and intra-particle diffusion contribute to the overall adsorption process. The monolayer adsorption on the surface of NS was primarily responsible for the elimination of ethylparaben. The adsorption mechanism showed that hydrophobic partitioning into organic matter could largely govern the adsorption process, rather than the Zn S that was the main component of NS. Furthermore, the ethylparaben adsorbed on the surface of NS was stable, as only less than 2% was desorbed and photochemically degraded under irradiation of simulated sunlight for 5 days. This study revealed that NS might serve as a potential natural remediation agent for some hydrophobic EOCs including parabens, and emphasized the significant role of naturally abundant minerals on the remediation of EOCs-contaminated water bodies. | Yanpeng Gao Teng Guo Xiaolin Niu Na Luo Jia Chen Junlang Qiu Yuemeng Ji Guiying Li Taicheng An | 2022 | Journal of Environmental Sciences2022，34，3： | 0 |
| 9 | Water quality soft-sensor prediction in anaerobic process using deep neural network optimized by Tree-structured Parzen Estimator显示文摘Anaerobic process is regarded as a green and sustainable process due to low carbon emission and minimal energy consumption in wastewater treatment plants(WWTPs).However,some water quality metrics are not measurable in real time,thus influencing the judgment of the operators and may increase energy consumption and carbon emission.One of the solutions is using a soft-sensor prediction technique.This article introduces a water quality soft-sensor prediction method based on Bidirectional Gated Recurrent Unit(BiGRU)combined with Gaussian Progress Regression(GPR)optimized by Tree-structured Parzen Estimator(TPE).TPE automatically optimizes the hyperparameters of BiGRU,and BiGRU is trained to obtain the point prediction with GPR for the interval prediction.Then,a case study applying this prediction method for an actual anaerobic process(2500 m^(3)/d)is carried out.Results show that TPE effectively optimizes the hyperparameters of BiGRU.For point prediction of CODeff and biogas yield,R^(2)values of BiGRU,which are 0.973 and 0.939,respectively,are increased by 1.03%–7.61%and 1.28%–10.33%,compared with those of other models,and the valid prediction interval can be obtained.Besides,the proposed model is assessed as a reliable model for anaerobic process through the probability prediction and reliable evaluation.It is expected to provide high accuracy and reliable water quality prediction to offer basis for operators in WWTPs to control the reactor and minimize carbon emission and energy consumption. | Junlang Li Zhenguo Chen Xiaoyong Li Xiaohui Yi Yingzhong Zhao Xinzhong He Zehua Huang Mohamed A.Hassaan Ahmed El Nemr Mingzhi Huang | 2023 | Frontiers of Environmental Science & Engineering2023，17，6： | 0 |
| 10 | Detecting gravitational wave with an interferometric seismometer array on lunar nearside显示文摘Our Moon is by far the easiest natural, extraterrestrial celestial object for us to reach, and many space agencies, in particular the China National Space Administration, have publicized plans for manned missions there. Such high-profile projects must yield commensurate scientific outputs to justify their cost to the taxpayers. An important criterion for the selection of candidate experiments is the extent to which the Moon plays an integral and irreplaceable role, as opposed to offering only marginal advantages over Earth-orbit, space-based alternatives. In this study, we propose an experiment that excels in this regard, which considers the Moon as part of the experimental apparatus. Specifically, the Moon acts as a Weber bar-style resonant mass that responds to deci-Hertz gravitational waves(GWs). GW-excited lunar vibrations can be picked up by an array of(prefabricated on Earth and easy to transport to the Moon) small laser interferometric seismometers yielding GW detection. Such a setup would plug a gap in the GW frequency range already covered by the existing or underdevelopment detectors, and it can inform us on important astrophysics topics, such as the progenitors of Type Ia supernovae(SNe Ia) or intermediate mass black holes. We provide the instrument design as well as its deployment strategy, and we also summarize relevant science cases according to the estimated viable sensitivity. | Junlang Li Fangfei Liu Yuan Pan Zijian Wang Mengdi Cao Mengyao Wang Fan Zhang Jinhai Zhang Zong-Hong Zhu | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，10： | 0 |
| 11 | Comparison of extruded cell nanovesicles and exosomes in their molecular cargos and regenerative potentials显示文摘Extracellular vesicles(EVs)generated from mesenchymal stem cells(MSCs)play an essential role in modulating cell–cell communication and tissue regeneration.The clinical translation of EVs is constrained by the poor yield of EVs.Extrusion has recently become an effective technique for producing a large scale of nanovesicles(NVs).In this study,we systematically compared MSC NVs(from extrusion)and EVs(from natural secretion).Proteomics and RNA sequencing data revealed that NVs resemble MSCs more closely than EVs.Additionally,microRNAs in NVs are related to cardiac repair,fibrosis repression,angiogenesis.Lastly,intravenous delivery of MSC NVs improved heart repair and cardiac function in a mouse model of myocardial infarction. | Xianyun Wang Shiqi Hu Dashuai Zhu Junlang Li Ke Cheng Gang Liu | 2023 | Nano Research2023，16，5： | 0 |
