Background: The segmental multi-frequency bioelectrical impedance analysis (SMF-BIA) is a useful method for evaluating physical health and nutritional status in various clinical settings. But less is known about its role in the preoperative assessment of breast cancer patients. Herein, we try to monitor the changes in body composition of preoperative patients by SMF-BIA and figure out its association with clinical features. Methods: The changes in body composition were monitored by SMF-BIA in 563 female patients with breast cancer. Monitor body moisture and collect relevant data on the day before surgery as a prospective study. Retrospective analysis will be conducted based on preoperative data and pathological results after lymph node resection, Spearman’s correlation coefficients were calculated to investigate the correlation among parameters. Results: We found that the body water, extracellular water ratio, and bioelectrical impedance of the affected upper limbs of patients with different tumor stages or different numbers of lymph node metastases were significantly different from those of their healthy upper limbs (P P P P P Conclusion: SMF-BIA can help monitor the changes in body composition of breast cancer patients and provide detailed information for making a personalized treatment plan and individual nursing schedule. However, the value of SMF-BIA in preoperative assessment still needs to be validated in large prospective clinical trials.

基于2009-2021年中国88家商业银行的平衡面板数据,通过固定效应估计和系统广义矩估计(GMM)方法,实证分析宏观审慎政策和货币政策对于银行风险承担的协同效应。研究发现,“双支柱”政策在银行风险承担方面能够产生较好的协同作用,加强宏观审慎管理整体能削弱宽松货币政策带来的银行风险承担上升;不同类型的宏观审慎工具与货币政策配合的有效性不同,银行流动性宏观审慎工具与货币政策对银行风险承担的协同作用更为显著;“双支柱”政策的协同效应因经济周期存在非对称性,经济下行期的协同效应要强于经济上行期;政策协同效应存在银行异质性,对于全国性银行“双支柱”政策协同作用不显著,而对于地方性银行则显著影响其风险承担意愿和水平。

针对无人机集群作战中如何分配打击目标的问题,将协同多任务分配模型CMTAP提升为两个维度的目标:时间窗适应度和油料消耗,将CMTAP问题的求解维度从分配任务序列拓展到了求解任务序列的对应速度和每架无人机的出发时间确定。针对该问题提出了CMTAP-MO-GA算法,其采用了一种破碎任务序列的染色体变异机制,和一种缺陷修复的染色体交叉机制。该算法能求解出问题在二维目标函数上的帕累托前沿,并获得前沿上每个解对应的分配结果及每个解的执行策略。

为了有效应对因过量糖摄入而引发的健康问题,探究甜味物质选择偏好及其感知机制至关重要。本研究以黑腹果蝇为模式动物,通过评估果蝇对能量糖(蔗糖、果糖、葡萄糖)和非能量代糖(山梨醇)的选择偏好,探究糖类偏好的特异性甜味感知受体机制。结果显示:与山梨糖醇相比,能量糖可以刺激雌性果蝇产更多的卵并显著影响产卵位置偏好。在甜味受体Gr5a层面,研究发现该受体在低浓度甜味基质的感知和行为调节中发挥了关键作用。在高浓度甜味基质中,即使Gr5a功能受损,雌性果蝇仍能进行有限的产卵,提示可能存在其它感知机制补偿了部分功能,多样化的感知机制使动物能够更有效地在环境中选择适合其需求的食物,从而优化营养选择。本研究揭示了果蝇在复杂糖环境中的感知和行为响应机制,为代糖在食品中的应用提供了科学依据,并为更广泛地减糖策略和健康饮食研究提供了新的视角和理论支持。

The separation of radionuclides is critical for the sustainable development of nuclear energy. It is urgent to design and prepare functionalized materials for efficient radionuclides separation. Porous materials are considered excellent candidates for the separation of radionuclides under complex conditions due to their high specific surface areas, tunable pore structures and controllable functionalities. In this review, we summarized the design, preparation and functionalization of porous materials and their application for separation of radionuclides in the past five years, discussed the separation performance and analyzed the structure-activity relationship between various radionuclides and porous materials, and systematically clarified their characterization and mechanism of different type porous materials. We also introduced the detection, irradiation and chemical toxicity of different reflective radionuclides.
