Drug-conjugated nanoparticle is a uniquely structured drug delivery system.In each conjugate,the nanoparticle acts as a core to crosslink more than 100 drug molecules.
Magnetic particle imaging(MPI)is a new imaging modality that uses time-varying magnetic fields to directly detect iron oxide nanoparticles.MPI is not MRI.Compared with existing modalities,MPI promises
The ammonium bicarbonate(ABC)liposomes have shown to release doxorubicin(DOX)rapidly at elevated temperatures(40-42oC)and improve the intravenous stability at physiological temperature(37oC)[1].
A major hurdle in small interfering RNA(siRNA)delivery is to balance the conflicting requirements for the design of the delivery vehicles: cationic materials facilitate cargo condensation and endosomo
Metastasis is the leading cause of high mortality in cancer patients,which is extremely diffcult to treat in clinic.A major issue is the limited delivery efficiency to cancer metastasis where many cur
目的 胎儿先天性血管环是一种罕见的先天性心脏病，本文旨在探讨胎儿超声心动图检查联合STIC技术在胎儿先天性血管环诊断及预后评估中的价值。方法 根据美国超声心动图学会制定的胎儿超声心动图检查规范与指南，对2014年3月-12月来我院行三级筛查的285例孕妇行产前胎儿超声心动图检查。检查过程中应用STIC技术采集心脏容积数据，数据存盘后进行图像后处理并脱机分析，总结胎儿先天性血管环心脏畸形的胎儿超声心
目的:通过与前列腺系统穿刺作比较,分析超声造影指导前列腺穿刺活检的临床应用价值.方法:选择我院因血清前列腺特异性抗原(PSA)升高的患者,共计186例,年龄49 ～ 89岁,平均(73.4±7.3)岁.PSA浓度4.0 ～ 100 ng/ml,平均(32.82±26.82) ng/ml.所有患者按照PSA值分成3组,即PSA值4～10,10 ～20及大于20.前两组采用12点系统穿刺法加超声造影目
