The early phase of phytohormone induction is a vital stage of somatic embryogenesis. This phase includes a key process for acquiring cellular totipotency through cellular dedifferentiation. To unravel the molecular mechanism of cellular dedifferentiation in cotton, we constructed a cDNA library using the suppression subtractive hybridization method. A total of 286 differential cDNA clones were sequenced and identified. Among these clones, 112 unique ESTs were significantly up-regulated during the early phase of phytohormone induction, and 40.2% of the ESTs were first identified. GST was highly expressed from 6 to 24 h after induction with phytohormone treatment. PRPs were predominantly expressed and exhibited distinct expression patterns in different treatments, suggesting that they are closely related to cellular dedifferentiation in cotton. Putative GhSAMS, GhSAMDC, GhSAHH and GhACO3 involvement in SAM metabolism was identified in this library. The analysis of qRT-PCR showed that two remarkable increased expressions of the four SAM-related genes happened during the early phase of phytohormone induction, and that a highly positive correlation existed between GhSAMS and GhSAHH. The highest expression level of GhSAMS might be associated with its reentry into the cell cycle. The histological observations further showed that some cells accomplished cellular dedifferentiation and division within 72 h in 2,4-D treatment, and that cellular dedifferentiation might be regulated through two alterations in SAM-dependent transmethylation activity in cotton. In addition, the expression patterns of differential genes in different treatments disclosed the complicated interaction between 2, 4-D and kinetin.

The in-depth integration of healthy China with national fitness and the hope to achieve the long-term goal of “leading Sports Nation” by 2035, can’t be realized without gyms where people do physical exercise. The international academic community recognizes that the 21st century is the golden time for sustainable and quality development. Taking a national perspective, authors of this paper studied the feasibility of building underground gyms in China through the approach of interdisciplinary research, as well as its dilemmas and pathways, and found out that quality development of underground space can effectively address challenges for large cities in China by increasing the resilience of urban area, and give full engage to underground capacity in striving for the goal of carbon peak and carbon neutrality. Underground gyms can also be incorporated into resident’s 15-min fitness circle, satisfying people’s needs of doing exercise at any time and in an easily-accessible place. However, China’s underground area development has been hindered by unclear property rights, chaotic action and utilization, and relatively backward laws and regulations. Moreover, building underground gyms still has to solve many problems such as poor air quality, severe sweat smell, and excessive bacteria and viruses. It is suggested that the capable authorities shall first clarify laws and regulations over place compound utilization, property rights and fire protection to facilitate the process of building underground gyms;encourage fitness practitioners to explore underground areas as gyms, and transfer their ground business to underground;then produce an intelligent and systematic solution of air quality improvement featuring oxygen-enrichment and “sterilization” with integration, a variety of instruments to monitor air quality of indoor gyms in real-time, to realize automatic control and management, and truly create worry-free and oxygen-enriched underground gyms with no sweat sme

五四前后,“儿童”概念所内含的现代性特征引起了作家的普遍关注,作为重要意象被迅速纳入到从白话诗到新诗的变革体系中,成为诗歌建构现代美学品格的重要元素。在五四文坛的话语实践中,“儿童”与民间、韵律和白话的天然联系不仅为新诗的现代表达提供了资源借鉴,其蕴含的启蒙新质也为“人”和“新人”主题展示了新的价值可能。以“儿童”为载体,五四新诗对如何“为人生”、创作出“真的文学”有过不断调整和形式探索,其贡献与局限深刻折射出新诗诞生初期的丰富性和复杂性,是百年诗歌研究不能忽视的另一个侧面。

五四时期"儿童"作为饱含现代色彩的启蒙符号在新文学话语体系中承担着重要功能。这一概念及叙事的内在丰富性,都使应运而生的儿童文学必然与五四新文学产生深刻关联,并体现出以"问题"为中心的叙事形态。在此语境下,以写小说进入文坛的叶圣陶创作了童话集《稻草人》,从选择独具时代"新"质的童话文体到叙事上取用"写实主义"风格,以及在书写"儿童"和话语表达上陷入的困境,无不成为五四新文学复杂多样的缩影。现代文学研究中未曾重视的《稻草人》,其历史贡献需要置于新文学整体框架以及作家创作的整体风格中考查,这将避免以往文献因忽略叶圣陶的小说家身份所做出的片面结论。

聚氨酯泡沫(PUF)具有弹性多孔、泡孔结构可控、形状可调、制备工艺简单、稳定性高、吸附/脱附速率快、易于分离、易于实现在线分离富集和自动化操作等特点,非常适合用作吸附分离材料。近来PUF在富集/分离金属离子方面应用广泛,PUF本身就对金属离子具有一定的吸附能力,但吸附量较低、选择性较差。修饰后的PUF,如物理负载、化学改性和复合PUF,其吸附性能和选择性得到了较大的提高,可实现对水中不同金属离子的吸附分离。重点介绍了不同形式的PUF,包括空白、物理负载、化学改性和复合PUF的制备,及其作为吸附剂对水中金属离子的富集/分离方面的研究进展。
