Forced oscillation of spherical and rod-shaped iron oxide magnetic nanoparticles (MNPs) via low-power and low-frequency alternating magnetic field (AMF) was firstly used to kill cancer cells in vitro. After being loaded by human cervical cancer cells line (HeLa) and then exposed to a 35-kHz AMF, MNPs mechanically damaged cell membranes and cytoplasm,(More)
During the past several decades, positron emission tomography (PET) has been one of the rapidly growing areas of medical imaging; particularly, its applications in routine oncological practice have been widely recognized. At present, (18)F-fluorodeoxyglucose ((18)F-FDG) is the most broadly used PET probe. However, (18)F-FDG also suffers many limitations.(More)
Gastric Schwannoma is a rare benign mesenchymal tumor that accounts for only 0.2% of all gastric tumors. The current study presents a case of gastric Schwannoma misdiagnosed as malignant gastrointestinal stromal tumor (GIST) by esophagogastroduodenoscopy, endoscopic ultrasonography, and contrast-enhanced or not enhanced and (18)F-FDG PET/CT imaging.
A divalent knottin containing two separate integrin binding epitopes (RGD) in the adjacent loops, 3-4A, was recently developed and reported in our previous publication. In the current study, 3-4A was radiofluorinated with a 4-nitrophenyl 2-(18)F-fluoropropinate ((18)F-NFP) group and the resulting divalent positron emission tomography (PET) probe,(More)
BACKGROUND This study aimed to determine whether synchrotron radiation (SR)-based X-ray in-line phase-contrast imaging (IL-PCI) can be used to investigate the morphological characteristics of tumor neovascularization in a liver xenograft animal model. METHODS A human hepatocellular carcinoma HCCLM3 xenograft model was established in nude mice. Xenografts(More)
OBJECTIVE To investigate the abnormal cerebral blood flow (CBF) perfusion in patients with internet addiction (IA) and its possible association with IA severity. SUBJECTS AND METHODS Thirty-five adolescents who met the criteria for IA and 12 matched healthy volunteers were recruited for (99m)Tc-ethylcysteinate dimer based CBF perfusion imaging with single(More)
SP94 (SFSIIHTPILPL), a novel peptide, has shown specific binding to hepatocellular carcinoma (HCC) cells. We aimed to investigate the capability of SP94 as a targeting probe for HCC imaging and therapy following labeling with technetium-99m ((99m)Tc) and rhenium-188 ((188)Re). HYNIC-SP94 was prepared by solid phase synthesis and then labeled with (99m)Tc.(More)
To the comments of Prof. Andreas Otte to our work we reply as follows: As was mentioned by Prof. Andreas Otte, our study was the first study of regional cerebral blood flow changes in patients with internet addiction. Therefore, there was not much previous, established experience to refer to. As an exploration study, it was inevitable that there were some(More)
It remains challenging to predict the risk of rupture for a specific atherosclerotic plaque timely, a thrombotic trigger tightly linked to inflammation. CD11b, is a biomarker abundant on inflammatory cells, not restricted to monocytes/macrophages. In this study, we fabricated a probe named as (99m)Tc-MAG3-anti-CD11b for detecting inflamed atherosclerotic(More)
Magnetic nanoparticles (MNPs) with special morphology were commonly used as biomaterials, while morphological effects of non-targeted biomolecule-modified MNPs on biological behaviors were still unclear. In this research, spherical and rod-like Fe3O4 in a comparable size were synthesized and then surface-modified by bovine serum albumin (BSA) as a model of(More)
