The farnesoid-X-receptor (FXR) is a member of the nuclear hormone receptor superfamily. The FXR has critical functions in maintaining bile acid synthesis and homeostasis, liver regeneration and tumorigenesis, intestinal diseases, intestinal tumorigenesis, cholesterol gallstone disease, cholestasis, and atherosclerosis. FXR expression is strongly(More)
BACKGROUND Emission-transmission misalignment with single-photon emission computed tomography (SPECT)-computed tomography (CT) systems can impair attenuation correction (AC) in myocardial perfusion imaging. This study was performed to develop automated quality control (Auto-QC) to detect critical misalignment that can significantly impact AC. METHODS AND(More)
Primary PSC in the lung is a rare malignant cancer that represents a particularly aggressive subtype of non-small cell lung carcinomas (NSCLC) containing sarcoma or sarcoma-like components with spindle or giant cell features. The medical literature referring to imaging characteristics by fluorine-18-fluorodeoxyglucose (¹⁸F-FDG) positron emission(More)
In this Letter, different from conventional pretargeting, an additional novel DNA polymer with multiple copies of a target was first designed to be administrated between the antitumor antibody, and the labeled effector served as an amplification pretargeting strategy. Two phosphorothioate DNA strands, a bridging and a target strand, were hybridized to form(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)
OBJECTIVE This study explores a new, non-invasive imaging method for the specific diagnosis of insulinoma by providing an initial investigation of the use of 125I-labelled molecules of the glucagon-like peptide-1 (GLP-1) analogue liraglutide for in vivo and in vitro small-animal SPECT/CT (single-photon emission computed tomography/computed tomography)(More)
PURPOSE Although intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy after hepatocellular carcinoma, there are limited data available on PET/CT imaging in ICC. This retrospective study analyzed the role of PET/CT imaging in the evaluation of ICC. METHODS FDG PET/CT findings were reviewed in 65 patients with(More)
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)
BACKGROUND The use of Rb positron emission tomography (PET) for the diagnosis of coronary artery disease (CAD) has increased in recent years but the role of some of the traditional parameters used in SPECT for the diagnosis of CAD, such as transient ischaemic dilation index (TID) of the left ventricle, have not been validated in PET studies. METHODS AND(More)
Atherosclerosis (AS), especially the vulnerable AS plaque rupture-induced acute obstructive vascular disease, is a leading cause of death. Accordingly, there is a need for an effective method to draw accurate predictions about AS progression and plaque vulnerability. Herein we report on an approach to constructing a hybrid nanoparticle system using a(More)
