| 1 | Tensile strength of sea ice using splitting tests based on the digital image correlation method显示文摘The splitting test is a competitive alternative method to study the tensile strength of sea ice owing to its suitability for sampling.However,the approach was questioned to the neglect of local plastic deformation during the tests.In this study,splitting tests were performed on sea ice,with 32 samples subjected to the regular procedure and 8 samples subjected to the digital image correlation method.The salinity,density,and temperature were measured to determine the total porosity.With the advantage of the digital image correlation method,the full-field deformation of the ice samples could be determined.In the loading direction,the samples mainly deformed at the ice-platen contact area.In the direction vertical to the loading,deformation appears along the central line where the splitting crack occurs.Based on the distribution of the sample deformation,a modified solution was derived to calculate the tensile strength with the maximum load.Based on the modified solution,the tensile strength was further calculated together with the splitting test results.The results show that the tensile strength has a negative correlation with the total porosity,which agrees with previous studies based on uniaxial tension tests. | CHEN Xiaodong HE Shuaikang HE Wenquan WANG Zhaoyu JI Shunying | 2021 | Advances in Polar Science2021，32，4： | 1 |
| 2 | Novel cyclophosphamide of natural products osalmide and pterostilbene induces cytotoxicity and cell cycle arrest in diffuse large B-cell lymphoma cells显示文摘Diffuse large B-cell lymphoma(DLBCL)is the most common category and disease entity of non-Hodgkin lymphoma.Osalmide and pterostilbene are natural products with anticancer activities via different mechanism.In this study,using a new synthetic strategy for the two natural products,we obtained the compound DCZ0801,which was previously found to have anti-multiple myeloma activity.We performed both in vitro and in vivo assays to investigate its bioactivity and explore its underlying mechanism against DLBCL cells.The results showed that DCZ0801 treatment gave rise to a dose-and time-dependent inhibition of cell viability as determined by CCK-8 assay and flow cytometry assay.Western blot analysis results showed that the expression of caspase-3,caspase-8,caspase-9 and Bax was increased,while BCL-2 and BCL-XL levels were decreased,which suggested that DCZ0801 inhibited cell proliferation and promoted intrinsic apoptosis.In addition,DCZ0801 induced G0/G1 phase arrest by downregulating the protein expression levels of CDK4,CDK6 and cyclin D1.Furthermore,DCZ0801 exerted an anti-tumor effect by down-regulating the expressions of p-PI3K and p-AKT.There also existed a trend that the expression of p-JNK and p-P38 was restrained.Intraperitoneal injection of DCZ0801 suppressed tum or development in xenograft mouse models.The preliminary metabolic study showed that DCZ0801 displayed a rapid metabolism within 30 min.These results demonstrated that DCZ0801 may be a new potential anti-DLBCL agent in DLBCL therapy. | Mengyu Xi Wan He Bo Li Jinfeng Zhou Zhijian Xu Huiqun Wu Yong Zhang Dongliang Song Liangning Hu Ye Lu Wenxuan Bu Yuanyuan Kong Gege Chen Shuaikang Chang Jumei Shi Weiliang Zhu | 2020 | Acta Biochimica et Biophysica Sinica2020，52，4： | 0 |
| 3 | antitumor activity in bortezomib-resistant multiple myeloma cells through inhibition of JAK2/STAT3 pathway显示文摘Multiple myeloma(MM),the second most common haematological malignancy,is currently incurable because patients often develop multiple drug resistance and experience subsequent relapse of the disease.This study aims to identify a potential therapeutic agent that can counter bortezomib(BTZ)resistance in MM.DCZ0358,a novel alkaloid compound,is found to exert potent cytotoxic effects against BTZ-resistant MM cells in vivo and in vitro.The antimyeloma activity of DCZ0358 is associated with inhibition of cell proliferation,promotion of cell apoptosis via caspase-mediated apoptotic pathways,and induction of G0/G1 phase arrest via downregulation of cyclin D1,CDK4,and CDK6.Further investigation of the molecular mechanism shows that DCZ0358 suppresses the JAK2/STAT3 signaling pathway.In conclusion,DCZ0358 can successfully counter BTZ resistance in MM cells.This study provides evidence that warrants future preclinical assessments of DCZ0358 as a therapeutic agent against BTZ resistance in MM. | Bibo Zhang Bo Li Yongsheng Xie Shuaikang Chang Zhijian Xu Huifang Hu Gege Chen Ting Zhang Jun He Xiaosong Wu Huabin Zhu Weiming Lai Dongliang Song Ying Lu Xinyan Jia Weiliang Zhu Jumei Shi | 2023 | Acta Biochimica et Biophysica Sinica2023，55，2： | 0 |
