Background Recent studies have shown the LyP-1 peptide can home to either tumor lymphatics or the tumor cells and be internalized by targeted cells. This study aimed to investigate the possibility of using Na1311 labeled LyP-1 peptide as an imaging agent or a therapeutic radiopharmaceutical in breast carcinoma and its metastasis. Methods The 10-mer cyclic peptide contained the LyP-1 sequence （YCGNKRTRGC） was synthesized by the solid phase method. Disulfide bonds between the cysteines maintain the cyclic structure. The LyP-1 peptide was labeled with Na1311 using the chloramine-T method. The [1311] LyP-1 peptide and a [1311] control peptide were injected via tail vein into nude mice bearing MDA-MB-435 tumor xenografts. Biodistribution and imaging results in vivo were obtained. Results The labeling efficiencies of LyP-1 peptide reached 80%＋5% （n=5）. The radiochemical purity was about 96%. The radiochemical purity of the labeled compound remains 92% at 24 hours in human serum at 37~C. In the biodistribution studies, the [1311] LyP-1 peptide accumulated in the tumor to a higher level than in other organs. The [1311] LyP-1 peptide can successfully image the tumor in nude mice bearing MDA-MB-435 tumor xenografts. Conclusions The LyP-1 peptide could be effectively labeled with Na1311 and the labeled compound is stable in human serum at 37℃ for 24 hours. The high specificity of [1311] LyP-1 peptide suggests it may be a promising new radiotracer for identifying tumors.

惯性约束聚变的设计要求在靶丸内形成均匀光滑的氘氚冰层,靶丸周围的热环境对冰层的质量特别是低阶粗糙度有很大的影响.本文对自主研发的黑腔冷冻靶实验装置中的热物理问题展开了数值模拟,重点考察了黑腔冷冻靶的传热和流体力学特性.通过参数分析得到了自然对流对靶丸温度均匀性产生影响的临界条件.比较了黑腔不同布置朝向时的流场和温度分布,结果显示黑腔水平布置时自然对流更加强烈,造成的靶丸温度不均匀性也更大.在此基础上,讨论了消除自然对流影响的可能性,结果发现仅当黑腔垂直布置时利用黑腔分区方法能够消除对流效应对靶丸温度不均匀性的影响而黑腔水平布置时不能消除.研究结论对于实验中冷冻靶结构的设计、改进和实验的开展等具有指导意义.

采用磁悬浮感应熔炼法制备VNi0.01合金,完全活化后,在含0.5%CO2的1.0 MPa毒化气氛中进行吸氘反应。在反应初期VNi0.01合金与纯V相比,仍保持较快的吸氘速率,随后合金吸氘速率迅速下降直至为零。样品毒化后经加热除气处理,样品室内再次充入1.0 MPa高纯氘气,VNi0.01合金吸氘速率已恢复至完全活化时的水平,而纯V的吸氘速率则低于初次活化时的吸氘速率。合金经活化后测得其增压性能在300～400K范围内均优于纯V,因而合金有望用于增压化学床。这些研究结果将为该材料的应用提供直接依据。
