＜正＞ In this paper, some properties of sup-product fuzzy relational equation are investigated when the domains are infinite sets. Some properties of its solution set will be obtained. We show a necessary and sufficient condition for existence of attainable solutions （resp. unattainable solution） and a necessary and sufficient condition that the solution sets are nonempty when I is a finite set and J is an infinite set. In the end, the number of minimal solutions will be given under some conditions.

N6-methyladenosine(m^(6)A), the most prevalent and conserved RNA modification in eukaryotic cells, profoundly influences virtually all aspects of mRNA metabolism. mRNA plays crucial roles in neural stem cell genesis and neural regeneration, where it is highly concentrated and actively involved in these processes. Changes in m^(6)A modification levels and the expression levels of related enzymatic proteins can lead to neurological dysfunction and contribute to the development of neurological diseases. Furthermore, the proliferation and differentiation of neural stem cells, as well as nerve regeneration, are intimately linked to memory function and neurodegenerative diseases. This paper presents a comprehensive review of the roles of m^(6)A in neural stem cell proliferation, differentiation, and self-renewal, as well as its implications in memory and neurodegenerative diseases. m^(6)A has demonstrated divergent effects on the proliferation and differentiation of neural stem cells. These observed contradictions may arise from the time-specific nature of m^(6)A and its differential impact on neural stem cells across various stages of development. Similarly, the diverse effects of m^(6)A on distinct types of memory could be attributed to the involvement of specific brain regions in memory formation and recall. Inconsistencies in m^(6)A levels across different models of neurodegenerative disease, particularly Alzheimer's disease and Parkinson's disease, suggest that these disparities are linked to variations in the affected brain regions. Notably, the opposing changes in m^(6)A levels observed in Parkinson's disease models exposed to manganese compared to normal Parkinson's disease models further underscore the complexity of m^(6)A's role in neurodegenerative processes. The roles of m^(6)A in neural stem cell proliferation, differentiation, and self-renewal, and its implications in memory and neurodegenerative diseases, appear contradictory. These inconsistencies may be a

Chemical Research in Chinese Universities 2013年第2期29卷 201-205页

Two new open-framework gallium phosphites formulated as （C2N2HI0）***2（OH）（H20）（HPO3）3（I） and （C3N2Hs）2（C3N2H6）Gas（H20）6（HPO3）14（2） were hydrothermally synthesized in the presence of ethylenediamine（en） and imidazole as structure directing agents（SDA）, respectively. Structural analyses reveal that the 3D structures of compounds I and 2 are both built up from the linkage ofGaO6, GaOs（H20） and HPO32 units by sharing vertices. The structure of compound 2 is constructed from well-known 4.6.12-net connecting layers in the AAAA stacking se- quence, which are oenetrated bv the 1D Ga--O--P chains to form a 3D pillared-layered structure.

Yield penalty of maize(Zea mays L.) under heat stress in different growth stages: A review

引用

Journal of Integrative Agriculture 2022年第9期21卷 2465-2476页

作者： LI Teng ZHANG xue-peng LIU qing LIU Jin CHEN Yuan-quan SUI Peng Key Laboratory of Farming Systems Ministry of Agriculture and Rural Affairs/College of Agronomy and BiotechnologyChina Agricultural UniversityBeijing 100193P.R.China

Maize(Zea mays L.) can exhibit yield penalties as a result of unfavorable changes to growing conditions. The main threat to current and future global maize production is heat stress. Maize may suffer from heat stress in all of the growth stages, either continuously or separately. In order to manage the impact of climate driven heat stress on the different growth stages of maize, there is an urgent need to understand the similarities and differences in how heat stress affects maize growth and yield in the different growth stages. For the purposes of this review, the maize growth cycle was divided into seven growth stages, namely the germination and seedling stage, early ear expansion stage, late vegetative growth stage before flowering, flowering stage, lag phase, effective grain-filling stage, and late grain-filling stage. The main focus of this review is on the yield penalty and the potential physiological changes caused by heat stress in these seven different stages. The commonalities and differences in heat stress related impacts on various physiological processes in the different growth stages are also compared and discussed. Finally, a framework is proposed to describe the main influences on yield components in different stages, which can serve as a useful guide for identifying management interventions to mitigate heat stress related declines in maize yield.
