PURPOSE Brain iron deposition has been proposed to play an important role in the pathophysiology of neurodegenerative diseases. The aim of this study was to investigate the correlation of brain iron accumulation with the severity of cognitive impairment in patients with Alzheimer disease (AD). MATERIALS AND METHODS This study was approved by the(More)
Surgical resection is the primary mode for glioma treatment, while gross total resection is difficult to achieve, due to the invasiveness of the gliomas. Meanwhile, the tumor-resection region is closely related to survival rate and life quality. Therefore, we developed optical/magnetic resonance imaging (MRI) bifunctional targeted micelles for glioma so as(More)
Conventional diffusion imaging techniques are not sufficiently accurate for evaluating glioma grade and cellular proliferation, which are critical for guiding glioma treatment. Diffusion kurtosis imaging (DKI), an advanced non-Gaussian diffusion imaging technique, has shown potential in grading glioma; however, its applications in this tumor have not been(More)
OBJECTIVE Most patients with stroke caused by middle cerebral artery occlusion (MCAO) show cognitive deficit that is generally regarded as resulting from damage to the cerebral cortex rather than the hippocampus. Whether MCAO induces hippocampal damage and whether this contributes to the cognitive defects remains unclear. Here we investigate the hippocampal(More)
Glioma is the most common primary brain tumor and causes a disproportionate level of morbidity and mortality across a wide range of individuals. From previous clinical practices, definition of glioma margin is the key point for surgical resection. In order to outline the exact margin of glioma and provide a guide effect for the physicians both at(More)
BACKGROUND Previous studies demonstrated that primary open angle glaucoma (POAG) is associated with abnormal brain structure; however, little is known about the changes in the local synchronization of spontaneous activity. The main objective of this study was to investigate spontaneous brain activity in patients with POAG using regional homogeneity (ReHo)(More)
The objective of this study was to successfully synthesize epidermal growth factor receptor monoclonal antibody-conjugated superparamagnetic iron oxide nanoparticles (EGFRmAb-SPIONs) and explore their biocompatibility and potential applications as a targeted magnetic resonance imaging (MRI) contrast agent for the EGFR-specific detection of brain glioma in(More)
Imaging markers derived from magnetic resonance images, together with machine learning techniques allow for the recognition of unique anatomical patterns and further differentiating Alzheimer's disease (AD) from normal states. T1-based imaging markers, especially volumetric patterns have demonstrated their discriminative potential, however, rely on the(More)
Resveratrol is a natural polyphenol derived mainly from the skin of grapes and from red wine. Resveratrol prolongs life span in several invertebrates, but this function is not found in mice. Our recently published paper demonstrated that resveratrol prolonged longevity of the annual fish Nothobranchius guentheri, a promising vertebrate model for anti-aging(More)
OBJECTIVE To explore the migration of transplanted neural stem cells co-labeled with superparamagnetic iron oxide (SPIO) and bromodeoxyuridine (Brdu) using the 4.7T MR system and to study the cell differentiation with immuno-histochemical method in ischemic rats. METHODS Rat neural stem cells (NSCs) co-labelled with SPIO mediated by poly-L-lysine and(More)
