| 1 | Stage-specific localization of transforming growth factor β1 and β3 and their receptors during spermatogenesis in men显示文摘Aim: To investigate the stage-specific localization of transforming growth factor (TGF) β1 and β3 during spermatogenesis in adult human testis, Methods: The localization of TGFβ1 and β3 was investigated by immunohistochemical staining method employing specific polyclonal antibodies. Results: Both TGFβ1 and β3 and their receptors were preponderant in the Leydig cells. TGFβ1 could not be detected in the seminiferous tubules. TGFβ3 and TGFβ-Receptor (R) Ⅰ were mainly seen in the elongated spermatids, while TGFβ-RⅡ in the pachytene spermatocytes and weak in the spermatogonia, spermatids and Sertoli cells. Only TGFβ-RⅡ was detected in the Sertoli cells.TGFβ3, TGFβ-RⅠ and TGFβ-RⅡ showed a staining pattern dependent upon the stages of the seminiferous epithelium cycle. Conclusion: TGFβ isoforms and their receptors are present in the somatic and germ cells of the adult humantestis, suggesting their involvement in the regulation of spermatogenesis. | Yuan-QiangZhang Xiao-ZhouHe Jin-ShanZhang Rui-AnWang JieZhou Ruo-JunXu | 2004 | Asian Journal of Andrology2004，6，2： | 18 |

| 6 | Collagen-based materials in reproductive medicine and engineered reproductive tissues显示文摘Collagen,the main component of mammal skin,has been traditionally used in leather manufacturing for thousands of years due to its diverse physicochemical properties.Collagen is the most abundant protein in mammals and the main component of the extracellular matrix(ECM).The properties of collagen also make it an ideal building block for the engineering of materials for a range of biomedical applications.Reproductive medicine,especially human fertility preservation strategies and reproductive organ regeneration,has attracted significant attention in recent years as it is key in resolving the growing social concern over aging populations worldwide.Collagen-based biomaterials such as collagen hydrogels,decellularized ECM(dECM),and bioengineering techniques including collagen-based 3D bio-printing have facilitated the engineering of reproductive tissues.This review summarizes the recent progress in apply-ing collagen-based biomaterials in reproductive.Furthermore,we discuss the prospects of collagen-based materials for engineering artificial reproductive tissues,hormone replacement therapy,and reproductive organ reconstruction,aiming to inspire new thoughts and advancements in engineered reproductive tissues research. | Hanxiao Chen Luqi Xue Guidong Gong Jiezhou Pan Xiaoling Wang Yaoyao Zhang Junling Guo Lang Qin | 2022 | Journal of Leather Science and Engineering2022，4，1： | 0 |
| 7 | Tail causalities between monetary supply and real estate prices in China显示文摘The asymmetric and segmented causality between the monetary policy and real estate market in China is crucial but remains mystery.With the application of quantile causality test,this article investigates nonlinear dependence between property prices and money supply.Our results show that the tail causality exists in many cities in China.Moreover,we find that small-sized cities and inland cities are more sensitive to the broad money(M2)changes when the housing market return is in the tail quantile intervals.These findings can help the Chinese government formulate appropriate monetary policies regarding their implications in the real estate market. | Haoyuan Ding Guoyong Liang Tong Qi Jiezhou Ying | 2020 | Economic and Political Studies2020，8，1： | 0 |

| 9 | Anti-dumping Policies and International Portfolio Allocation:The View from the Global Funds显示文摘Anti-dumping policies,as one of the most important nontariff measures to protect a country's economic interests,can have an impact not only on a country's trade and social welfare,but also on capital fows.Anti-dumping measures can result in increased trade costs and alterations to exchange rate risk.This study investigates the impact of anti-dumping sanctions on the international portfolio allocations of global funds.Anti-dumping policies can decrease the proportion of a fund's investment portfolio allocated to recently-sanctioned countries.Closer trade ties between the sanctioned country and the country where a fund is domiciled exacerbate the divestiture,but stronger foreign direct investment links weaken the negative association.Some country and fund heterogeneities are also discussed.We find that more developed countries are less affected by the impact of anti-dumping measures on equity fund allocations;liberalization of the economy and stable government could also mitigate the negative impact of anti-dumping sanctions.High-risk funds,such as growth funds or funds that invest in leveraged buyouts,showed the greatest response to changes in anti-dumping regulations. | Haoyuan Ding Xiao Li Jiezhou Ying | 2023 | China & World Economy2023，31，2： | 0 |
| 10 | A biologically stable, self-catalytic DNAzyme machine encapsulated by metal-phenolic nanoshells for multiple microRNA imaging显示文摘DNAzyme machines play critical roles in the fields of cell imaging, disease diagnosis, and cancer therapy. However, the applications of DNAzyme machines are limited by the nucleases-induced degradation,non-specific binding of proteins, and insufficient provision of cofactors. Herein, protected DNAzyme machines with different cofactor designs(referred to as Pro Ds) were nanoengineered by the construction of multifunctional metal-phenolic nanoshells to deactivate the interferential proteins, including nucleases and non-specific binding proteins. Moreover, the nanoshells not only facilitate the cellular internalization of Pro Ds but provide specific metal ions acting as cofactors of the designed DNAzymes. Cellular imaging results demonstrated that Pro Ds could effectively and simultaneously monitor multiple tumor-related micro RNAs in living cells. This facile and rapid strategy that encapsulates DNAzyme machines into the protective metal-phenolic nanoshells is anticipated to extend to a wide range of functional nucleic acidsbased biomedical applications. | Xin Jin Qin Wang Jiezhou Pan Jin Wang Yunxiang He Jiaojiao Shang Mei Chen Xianglian He Yaoyao Zhang Bo Wang Yajie Wang Guidong Gong Junling Guo | 2023 | Chinese Chemical Letters2023，34，10： | 0 |
| 11 | Tail Causality between Crude Oil Price and RMB Exchange Rate显示文摘In this paper we assess the causal relationship between international crude oil price changes and the RMB exchange rate using daily information from 21 July 2005 to 5 April 2017.In addition to linear causality tests,we employ quantile causality test to.identify prior imperceptible causplity in quantiles.We find a causal relationship from crude oil price to exchange rate at each quantile interval,but the reverse only appears in tail.This may help to explain why a traditional linear test fails to capture the causality from exchange rate to crude oil price as the quantile causalities in tails are canceled out by each other:Moreover;using RMB as the settlement currency in crude oil trade can weaken the prior significant causal relationships between crude oil price and exchange rate,whereas the reform of exchange rate marketization reignites the tail causalities from exchange rate to crude oil price.These findings recommend a wider use of domestic currencies in crude oil trade to avoid risk from the crude oil market. | Haoyuan Ding Yuying Jin Cong Qin Jiezhou Ying | 2020 | China & World Economy2020，28，3： | 0 |
