Decidual natural killer（dNK） cells are the most abundant immune cells at the maternal-fetal interface during early pregnancy in both mice and humans, and emerging single-cell transcriptomic studies have uncovered various human dNK subsets that are disrupted in patients experiencing recurrent early pregnancy loss（RPL） at early gestational stage, suggesting a connection between abnormal proportions or characteristics of dNK subsets and RPL pathogenesis. However, the functional mechanisms underlying this association remain unclear. Here, we established a mouse model by adoptively transferring human dNK cells into pregnant NOG（NOD/Shi-scid/IL-2Rγnull） mice, where human dNK cells predominantly homed into the uteri of recipients. Using this model, we observed a strong correlation between the properties of human dNK cells and pregnancy outcome. The transfer of dNK cells from RPL patients（dNK-RPL）remarkably worsened early pregnancy loss and impaired placental trophoblast cell differentiation in the recipients. These adverse effects were effectively reversed by transferring CD56+CD39+dNK *** studies revealed that CD56+CD39+dNK subset facilitates early differentiation of mouse trophoblast stem cells（m TSCs） towards both invasive and syncytial pathways through secreting macrophage colony-stimulating factor（M-CSF）. Administration of recombinant M-CSF to NOG mice transferred with dNK-RPL efficiently rescued the exacerbated pregnancy outcomes and fetal/placental development. Collectively, this study established a novel humanized mouse model featuring functional human dNK cells homing into the uteri of recipients and uncovered the pivotal role of M-CSF in fetal-supporting function of CD56+CD39+dNK cells during early pregnancy, highlighting that M-CSF may be a previously unappreciated therapeutic target for intervening RPL.

With the focus of urban regeneration gradually shifting to the community level, community regeneration has become an important path for improving residents' quality of life and the governance of grassroots society. How to innovate the governance model and how to improve the community public space utilization efficiency become vital questions. From the perspective of property rights regime, this paper puts forward the theoretical framework of “property rights regime-governance model-space utilization,” and argues that the property rights regime can be adjusted through the subdivision of property rights, which can change the governance model of public space and affect the space utilization efficiency. Through an in-depth investigation of the community regeneration of Shanghai KIC Garden, this study finds that different property rights regimes affect the process and results of collective action in public space governance, and the monocentric governance model formed by the concentration of governmental power can easily lead to the governance dilemmas such as rent-seeking, ineffective supervision, and information asymmetry. By subdividing and decentralizing property rights, social organizations, and community residents can be introduced to participate in the process of spatial governance, so as to facilitate the sinking of governance centers to the grassroots level and form a polycentric governance model. Moreover, multiple stakeholders can be motivated to make full use of public space through the property rights regime adjustment, and the public space utilization efficiency can be enhanced as a result.

过渡金属二硫族化合物(TMDs)是二维材料家族中的重要成员,具有丰富多样的晶体结构和物理特性,是近年来在科学研究和器件应用领域关注度较高的材料之一.本文通过第一性原理计算研究了单层RuSe_(2)的结构和相变,在确定其基态为二聚相(T′相)的同时,发现该材料存在能量相近的三聚相(T′″相).分别从动力学和热力学角度预测了该晶相结构的稳定性.结合相变势垒的计算和分子动力学模拟,预测在室温下对相结构施加较小的应力就可以实现晶格从T′相到T′″相的转变.相变后的能带结构以及载流子迁移率都发生了明显的改变,其带隙由1.11 eV的间接带隙转变为0.71 eV的直接带隙,载流子迁移率有了大幅的提升,空穴迁移率达到了3.22×10^(3)cm^(2)·V^(-1)·s^(-1).本文对比研究了RuSe_(2)单层中可能共存的两种畸变相,分析了不同晶相的电子结构和迁移率,为实验上研究二维RuSe_(2)材料及其在未来器件中的应用提供了理论依据.

Highland barley tea (HBT) is made from roasted barley seeds and is abundant in β-glucan， amino acids， minerals， phenolics， and other natural active ingredients. These natural compounds found in whole grains have been shown to slow aging and positively affect skeletal muscle function. As a result， studying the effects of HBT on the skeletal muscle health of the elderly population is critical from a scientific and societal standpoint for improving their health status and reducing the medical burden on society. The antioxidant activity and the content of natural active substances were used as indicators to screen the optimal process of HBT brewing. The effects of long-term HBT consumption on aging in mice were investigated by using HBT as a substitute for drinking water in naturally aging mice for a 5-month intervention. Afterward， various factors were measured， such as basic physiological indices， inflammation， plasma metabolites， skeletal muscle function， and exercise capacity， to evaluate the effects of HBT on aging in mice. Long-term consumption of HBT reduced body and spleen weight， increased body weight percentage of skeletal muscle， and reduced plasma inflammation levels in aging mice. Metabolomic results showed increased plasma levels of the mitochondrial marker short-chain acylcarnitine and some amino acids. Additionally， there was a decrease in bile and long-chain acylcarnitine. The level of fibrosis in the gastrocnemius muscle of aging mice was suppressed， and the percentage of type I muscle fibers was increased， improving the endurance of the mice. Thus， long-term consumption of HBT may reduce body weight and increase skeletal muscle mitochondrial activity and exercise capacity in aging mice by reducing inflammation levels and alleviating mitochondrial damage.
