2Current understanding of ovarian aging显示文摘The reproductive system of human female exhibits a much faster rate of aging than other body systems.Ovarian aging is thought to be dominated by a gradual decreasing numbers of follicles,coinciding with diminished quality of oocytes.Menopause is the final step in the process of ovarian aging.This review focuses on the mechanisms underlying the ovarian aging involving a poor complement of follicles at birth and a high rate of attrition each month,as well as the alternated endocrine factors.We also discuss the possible causative factors that contribute to ovarian aging,e.g.,genetic factors,accumulation of irreparable damage of microenvironment,pathological effect and other factors.The appropriate and reliable methods to assess ovarian aging,such as quantification of follicles,endocrine measurement and genetic testing have also been discussed.Increased knowledge of the ovarian aging mechanisms may improve the prevention of premature ovarian failure.LI Qian GENG XiaoDan ZHENG Wei TANG Jie XU Bo SHI QingHua 2012Science China(Life Sciences)2012,55,8:14
3Olfactory ecto-mesenchymal stem cell-derived exosomes ameliorate murine Sjögren’s syndrome by modulating the function of myeloid-derived suppressor cells显示文摘Sjögren’s syndrome(SS)is a systemic autoimmune disease characterized by progressive inflammation and tissue damage in salivary glands and lacrimal glands.Our previous studies showed that myeloid-derived suppressor cells(MDSCs)exhibited impaired immunosuppressive function during disease progression in patients with SS and mice with experimental Sjögren’s syndrome(ESS),but it remains unclear whether restoring the function of MDSCs can effectively ameliorate the development of ESS.In this study,we found that murine olfactory ecto-mesenchymal stem cell-derived exosomes(OE-MSC-Exos)significantly enhanced the suppressive function of MDSCs by upregulating arginase expression and increasing ROS and NO levels.Moreover,treatment with OE-MSC-Exos via intravenous injection markedly attenuated disease progression and restored MDSC function in ESS mice.Mechanistically,OE-MSC-Exo-secreted IL-6 activated the Jak2/Stat3 pathway in MDSCs.In addition,the abundant S100A4 in OE-MSC-Exos acted as a key factor in mediating the endogenous production of IL-6 by MDSCs via TLR4 signaling,indicating an autocrine pathway of MDSC functional modulation by IL-6.Taken together,our results demonstrated that OE-MSC-Exos possess therapeutic potential to attenuate ESS progression by enhancing the immunosuppressive function of MDSCs,possibly constituting a new strategy for the treatment of Sjögren’s syndrome and other autoimmune diseases.Ke Rui Yue Hong Qiugang Zhu Xiaofei Shi Fan Xiao Hailong Fu Qing Yin Yida Xing Xinfeng Wu Xiaodan Kong Huaxi Xu Jie Tian Shengjun Wang Liwei Lu 2021Cellular & Molecular Immunology2021,18,2:12
4Decrement of Sugar Consumption in Rice Young Panicle Under High Temperature Aggravates Spikelet Number Reduction显示文摘Two rice genotypes Huanghuazhan(HHZ, heat-resistant) and IR36(heat-susceptible) were subjected to high-temperature(HT, 40℃) and normal-temperature(NT, 32℃) treatments at the spikelet differentiation stage. HT treatment inhibited spikelet differentiation, aggravated spikelet degeneration, reduced spikelet size, and disordered carbohydrate allocation. Meanwhile, HT treatment increased nonstructural carbohydrate content in leaves, but decreased that in stems and young panicles, and the same tendencies of sucrose and starch contents were observed in leaves and stem. However, HT treatment significantly increased the sucrose content and sharply decreased the glucose and fructose contents in young panicles. Lower activity levels of soluble acid invertase(EC3.2.1.26) and sucrose synthase(EC2.4.1.13) were observed under HT treatment. Moreover, HT treatment reduced the activities of key enzymes associated with glycolysis and the tricarboxylic acid cycle, which indicated sucrose consumption was inhibited in young panicles under HT treatment. Exogenous glucose and fructose applied under HT treatment increased the spikelet number more than exogenous sucrose. In conclusion, the results demonstrated that the reduction of spikelet number under high temperature was more affected by the decrease in sugar consumption than the blocking of sucrose transport. The impairment of sucrose hydrolysis was the main reason for the inhibition of sugar utilization.WANG Yaliang ZHANG Yikai SHI Qinghua CHEN Huizhe XIANG Jing HU Guohui CHEN Yanhua WANG Xiaodan WANG Junke YI Zihao ZHU Defeng ZHANG Yuping 2020Rice science2020,27,1:6
5Advances in preimplantation genetic diagnosis/screening显示文摘Preimplantation genetic diagnosis(PGD)gives couples who have a high risk of transmitting genetic disorders to their baby the chance to have a healthy offspring through embryo genetic analysis and selection.Preimplantation genetic screening(PGS)is an effective method to select euploid embryos that may prevent repeated implantation failure or miscarriage.However,how and to whom PGS should be provided is a controversial topic.The first successful case of PGD of a human being was reported in 1990,and there have been tremendous improvements in this technology since then.Both embryo biopsy and genetic technologies have been improved dramatically,which increase the accuracy and expand the indications of PGD/PGS.YAN LiYing WEI Yuan HUANG Jin ZHU XiaoHui SHI XiaoDan XIA Xi YAN Jie LU CuiLing LIAN Ying LI Rong LIU Ping QIAO Jie 2014Science China(Life Sciences)2014,57,7:3
6Ultrafine monolayer Co-containing layered double hydroxide nanosheets for water oxidation显示文摘For many two-dimensional(2D)materials,low coordination edges and corner sites offer greatly enhanced catalytic performance compared to basal sites,motivating the search for new synthetic approaches towards ultrathin and ultrafine 2D nanomaterials with high specific surface areas.To date,the synthesis of catalysts that are both ultrathin(monolayer)and ultrafine(lateral size<10nm)has proven extremely challenging.Herein,using a facile ultrasonic exfoliation procedure,we describe the successful synthesis of ultrafine ZnCo-LDH nanosheets(denoted as ZnCo-UF)with a size^3.5 nm and thickness^0.5 nm.The single layer ZnCo-UF nanosheets possess an abundance of oxygen vacancies(Vo)and unsaturated coordination s让es,thereby affording outstanding electrocatalytic water oxidation performance.DFT calculations confirmed that Vo on the surface of ZnCo-UF enhanced H20 adsorption via increasing the electropositivity of the nanosheets.Xiaodan Jia Xin Zhang Jiaqing Zhao Yufei Zhao Yunxuan Zhao Geoffrey I.N.Waterhouse Run Shi Li-Zhu Wu Chen-Ho Tung Tierui Zhang 2019Journal of Energy Chemistry2019,28,7:3

12Enhanced thermoelectric properties of SnSe thin films grown by pulsed laser glancing-angle deposition显示文摘SnSe single crystals have been demonstrated to possess excellent thermoelectric properties.In this work,we demonstrate a grain size control method in growing nanocrystalline SnSe thin films through a glancing angle pulsed-laser deposition approach.Structural characterization reveals that the SnSe film deposited at a normal angle has a preferred orientation along a axis,while by contrast,the SnSe film deposited at an 80glancing angle develops a nanopillar structure with the growth direction towards the incident atomic flux.The glancing angle deposition greatly reduces the grain size of the thin film due to a shadowing effect to the adatoms,resulting in significantly increased power factor for more than 100%.The maximum Seebeck coefficient and power factor are 498.5 mV=K and 18.5 mWcm^(-1)K^(-2),respectively.The enhancement of thermoelectric property can be attributed to the potential barrier scattering at grain boundaries owing to the reduced grain size and increased grain boundaries in the film.Given this enhanced power factor,and considering the fact that the nanopillar structure should have much lower thermal conductivity than a plain film,the zT value of such made SnSe film could be significantly larger than the corresponding single crystal film,making it a good candidate for thin film-based thermoelectric device.Chun Hung Suen Dongliang Shi Y.Su Zhi Zhang Cheuk Ho Chan Xiaodan Tang Y.Li Kwok Ho Lam Xinxin Chen B.L.Huang X.Y.Zhou Ji-Yan Dai 2017Journal of Materiomics2017,3,4:1

19Gel electrolytes containing several kinds of particles used in quasi-solid-state dye-sensitized solar cells显示文摘Composite gel electrolytes containing several kinds of particles used as the quasi-solid-state electrolytes in dye-sensitized solar cells (DSSCs) were reported. Mesoporous particles (MCM-41) with unique structures composed of ordered nanochannels were served as a new kind of gelator for quasi-solid-state electrolytes. MCM-41, hydrophobic fumed silica Aerosil R972 and TiO2 nanopatricles P25 were dispersed into gel electrolytes respectively. The solar energy-to-electricity conversion efficiency of these cells is 4.65%, 6.85% and 5.05% respectively under 30 mW·cm-2 illumination. The preparation methods and the particles sizes exert an influence on the performance of corresponding solar cells. Owing to unique pore structures and high specific BET surface area, mesoporous silica MCM-41 was expected to have the potential to afford conducting nanochannels for redox couple diffusion.GENG Yi SUN Xiaodan CAI Qiang SHI Yantao LI Hengde 2006Rare Metals2006,25,z1:1
20Suppressed recombination for monolithic inorganic perovskite/silicon tandem solar cells with an approximate efficiency of 23%显示文摘Potentially temperature-resistant inorganic perovskite/silicon tandem solar cells(TSCs)are promising devices for boosting efficiency past the single-junction silicon limit.However,undesirable non-radiative recombination generally leads to a significant voltage deficit.Here,we introduce an effective strategy using nickel iodide,an inorganic halide salt,to passivate iodine vacancies and suppress non-radiative recombination.NiI_(2)-treated CsPbI_(3-x)Br_(x) inor-ganic perovskite solar cells with a 1.80 eV bandgap exhibited an efficiency of 19.53%and a voltage of 1.36 V,corresponding to a voltage deficit of 0.44 V.Importantly,the treated device demonstrated excellent operational stability,maintaining 95.7%of its initial efficiency after maximum power point tracking for 300 h under continuous illumination in a N_(2) atmosphere.By combining this inorganic perovskite top cell with a narrower bandgap silicon bottom cell,we for the first time achieved monolithic inorganic perovskite/silicon TSCs,which exhibited an effi-ciency of 22.95%with an open-circuit voltage of 2.04 V.This work provides a promising strategy for using inorganic passivation materials to achieve efficient and stable solar cells.Sanlong Wang Pengyang Wang Bingbing Chen Renjie Li Ningyu Ren Yucheng Li Biao Shi Qian Huang Ying Zhao Michael Grätzel Xiaodan Zhang 2022eScience2022,2,3:1
