  • Patent number: 11331396
    Abstract: Radiation therapy or radiotherapy (RT) is a powerful treatment where precision and accuracy is crucial. Image Guided Radiotherapy (IGRT) facilitates more accurate position verification, correcting for anatomic changes related to internal organ movement. IGRT thereby helps reduce toxicity of radiotherapy and increases relapse-free survival. An inter-correlation point with a fixed position and volume (a marker) can be applied to indicate the point of treatment clearly in both imaging modalities and to localize and track tumors in real time. In this study, we present the development of a marker based on lactose octaacetate:octapropionate 1:1 containing 3 mM PLA-DTPA(Gd), 40% triglyceride, 5% propylene carbonate and 10% XSAIB (sucrose based CT-contrast agent). The injectable marker had high CT contrast (>1000 HU) and displayed clearly visible, stable T1 contrast enhancement (T1˜900 ms) in the rim over at least 3 weeks with clinically observable resolution.

  • Patent number: 11318105
    Abstract: A method for preparing albumin nanoparticles based on free radical oxidation, comprising the following steps: preparing albumin aqueous solution with an albumin concentration of 1-20 mg/mL; (2) whilst stirring, adding free radical generating agent to the albumin aqueous solution, and continuing to stir and react for 1-60 min at 15-50° C.; the free radicals generated by the free radical generating agent are used for oxidizing the albumin, and the oxidized albumin molecules assemble to form albumin nanoparticles that are mainly bonded by hydrophobic action, thereby obtaining an albumin nanoparticle suspension. The present invention implements improvement by means of the key reaction mechanism of the nanoparticle preparation method and the corresponding design of the finishing process and, compared to the prior art, can effectively solve the problems of the complexity, high cost, and high toxicity of preparing nanoparticles.
