1 Introduction Thanks very much for *** taking time to comment on our recent paper regarding“Chemical vapor deposition synthesis and Raman scattering investigation of quasi-one-dimensional ZrS_(3) nanoflakes”.We summarize the suggestions of *** as made in the comment[1].First,*** suggested that there are just three peaks of two S 2p doublets in Fig.2(b)in the original paper[1],which is inconsistent to the four peaks of previous reports[2-4].Second,*** mentioned that the ratio of two S 2p doublets is helpful to identify the sulfur vacancies,which have a great impact on the n-type semiconducting nature of ZrS_(3).Third,*** mentioned that Zr 3d peak appearing at 184.7 eV is wider than previous reports[2,4],which may be accounted by the appearance of ZrS_(2)O,and Zr remains in the tetravalent state.

采用多通道压力采集系统测量了GeldartB类颗粒(树脂)矩形流化床(2.000m×0.300m×0.025m)内的压力波动,探索了流化床内的压力波动特征;同时采用标准方差、自相关和互相关函数分析了表观气速和静床高度对压力波动、压力波速度和压力波主频的影响。结果表明,气泡行为(如:气泡的形成、发展、聚并和破碎)是影响流化床内压力波动的主要因素;密相和稀相界面处的压力波动幅值主要由气泡崩塌决定;压力波在流化床内进行传播,并且具有明显的周期性特征;此外,压力波动、压力波速度和压力波主频均与表观气速和静床高度密切相关。

Edible mushroom polysaccharides demonstrate a range of bioactivities and have been investigated as potential adjuvant therapies for cancer treatment. Our prior research found Lactariks hatsudake Tanaka polysaccharide (LHP) effective against hepatocellular carcinoma， but the mechanisms remain unclear. This study aims to clarify the anti-cancer molecular mechanisms by examining the effects on specific signaling pathways through in vivo and in vitro analyses. Animal studies showed that LHP significantly inhibited the growth of transplanted liver cancer without toxicity. Histological and immunohistochemical analyses revealed that LHP increased nuclear cohesion in tumor cells and altered the expression of key regulatory proteins such as Ak strain transformation， nuclear factor kappa B， caspase-3， p21， and p53. These findings suggest that LHP's anticancer effects involve promoting apoptosis and disrupting the cell cycle. At the cellular level， assays such as MTS， flow cytometry， and transwell invasion confirmed that LHP inhibited cancer cell proliferation and induced apoptosis. Polymerase chain reaction and western blot assays revealed that LHP intervention reduced cyclin-dependent kinase 4 activity by upregulating p53 and p21， leading to cell cycle arrest and inhibited cell proliferation. LHP also promoted apoptosis by altering Bcl-2-associated X protein， B-cell lymphoma 2， and cleaved caspase-3 levels. Moreover， LHP could affect the Ak strain transformation， nuclear factor kappa B， and mitogen-activated protein kinase signaling pathways to exert anticancer effects. These findings underscore the potential of LHP as a novel and multifaceted therapeutic agent. Furthermore， the elucidation of LHP-related mechanisms offers a crucial theoretical foundation for developing innovative and effective treatments for hepatocellular carcinoma. Additionally， this supports its potential development as a functional food or adjuvant therapy for cancer， which holds significant implication
