Herein, iRGD-modified graphene oxide (GO) loaded 131I are developed for the specific treatment of PTC strengthened integrin targeting. Fine structural characteristics of GO and GO-iRGDs were characterized by fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEC), Raman spectrum and X-ray photoelectron spectroscopy (XPS). The results showed that there were characteristic peaks and chemical bonds on GO and GO-iRGDs by FT-IR, the D-peak and G-peak of GO disappeared by Raman spectrum and C-N bond with iRGD of GO-iRGDs were strong by XPS. These 131I-GO-iRGDs and 131I-GOs were taken up by PTC cell (TPC-1, BCPAP, and IHH-4) through endocytosis after 48 h and 72 h in cell uptake test, especially the uptake rate of 131I-GO50-iRGD was the highest. The CCK-8 cytotoxicity test of 131I-GO-iRGDs and 131I-GOs showed that these nanoparticles toxicity were higher than that of Na131I and finally promoted PTC death. In vitro data verified the targeting mechanism of GO and 131I for PTC cell line is based on the relevant advantages of binding cell, followed by iRGD-endowed cell surface transport. The tailored design of GO-iRGDs validates a promising paradigm for radioisotope (131-iodine) delivery to combat PTC resistance and metastasis resulting from poor target access for effective combination therapy.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 2","pages":"1577 - 1587"},"PeriodicalIF":1.5,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10967-025-09985-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Daughter products resulting from these decay processes can introduce complicating factors to the integrity and safety of the vessel that contains the radiological material. Sources containing cesium 137 ((^{137})Cs) are of particular interest, because the decay of this isotope produces barium metal which reacts readily and exothermically with oxygen. This work employs physics-based numerical tools to examine the thermal response of a radiological source containing a mixture of cesium and barium in the event that vessel walls are damaged and atmospheric gases contact source material. A parametric study was conducted to determine the sensitivity of the response to various factors, including vessel geometry, source material age, the degree of vessel damage, and other parameters. It was found that the peak temperatures that occurred within the source material strongly depend on these parameters, particularly vessel geometry and age, which determine whether a breach would be a relatively minor accident or a catastrophic incident. Finally, the model’s sensitivity to uncertain thermophysical properties is discussed.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 3","pages":"2061 - 2071"},"PeriodicalIF":1.5,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under particular conditions (pH = 2, Ci = 1.0 mg L−1, T = 55 °C, 80 rpm, and dosage = 2 g L−1), sorption equilibrium is reached in 40 min, resulting in the greatest elimination percentage of 90%.

All the simulations are made considering a thermalised Am-Be neutron source. The simulations are validated, qualitatively and quantitatively, by comparing the simulated energy spectra and sensitivity values with those obtained from experimental measurements carried out using two different thicknesses of the crystal from our own experiment (0.5 mm and 3 mm) and validated with three other thicknesses (0.01 mm, 0.1 mm and 1 mm) from literature (Taggart et al. in IEEE Trans Nucl Sci 67:603–608, 2020). In this study, we define sensitivity of GAGG:Ce as the ratio of area under 77 keV sum peak to 45 keV peak. The present studies clearly confirm that, while it requires about 0.1 mm thickness for the GAGG:Ce crystal to fully absorb thermal neutrons, it requires about 3 mm to fully absorb the thermal neutron induced events. Further, we propose an equation, that can be used to estimate the thickness of the GAGG:Ce crystal directly from the observed sensitivity of the GAGG:Ce crystal. This equation could be very useful for the neutron imaging community for medical and space applications, as well as for manufactures of cameras meant for nuclear security purposes.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 3","pages":"2203 - 2210"},"PeriodicalIF":1.5,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10967-024-09976-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
