BACKGROUND AND PURPOSE Mitochondrial dysfunction has been implicated in the cell death observed after cerebral ischemia, and several mechanisms for this dysfunction have been proposed. Reperfusion after transient cerebral ischemia may cause continued and even more severe damage to the brain. Many lines of evidence have shown that mitochondria suffer severe(More)
[(18)F]FPPRGD2, an F-18 labeled dimeric cyclic RGDyK peptide, has favorable properties for PET imaging of angiogenesis by targeting the α(v)β(3) integrin receptor. This radiotracer has been approved by the FDA for use in clinical trials. However, the time-consuming multiple-step synthetic procedure required for its preparation may hinder the widespread(More)
OBJECTIVE The accuracy of diagnosis of intracranial aneurysms by subtraction computed tomography angiography (CTA) was compared with conventional non-subtracted CTA and with digital subtraction angiography (DSA). METHODS 56 patients with spontaneous subarachnoid hemorrhage (SAH) and suspected intracranial aneurysms were evaluated from September 2009 to(More)
Melanoma is an aggressive skin cancer with worldwide increasing incidence. Development of positron emission tomography (PET) probes for early detection of melanoma is critical for improving the survival rate of melanoma patients. In this research, (18)F-picolinamide-based PET probes were prepared by direct radiofluorination of the bromopicolinamide(More)
Recent studies suggested an association of endothelial microRNA-126 (miR-126) with type 2 diabetes mellitus (T2DM). In the current study, we examined whether circulating miR-126 is associated with T2DM and pre-diabetic syndrome. The study included 82 subjects with impaired glucose tolerance (IGT), 75 subjects with impaired fasting glucose (IFG), 160(More)
PURPOSE The purpose of this article is to evaluate fast-track rehabilitation program and conventional care after esophagectomy using a retrospective controlled cohort study in esophageal cancer patients. METHODS Fifty-five patients underwent fast-track rehabilitation program and 57 patients underwent conventional care after esophagectomy. Fast-track(More)
MicroRNA-21 (miR-21) is overexpressed in a wide range of cancers and involved in tumor proliferation and metastasis. However, the potential function of miR-21 in regulating tumor angiogenesis has been little disclosed. In this study, we treated the cultured 4T1 murine breast cancer cells and human umbilical vein endothelial cells (HUVECs) with miR-21 mimic,(More)
PURPOSE Osteosarcoma represents the most common malignant primary bone tumor in childhood; however, the survival rate has remained unchanged for the past 20 years. To improve existing diagnosis and treatment methods and broaden the spectrum of imaging agents that can be used for early detection and assessment of tumor response to therapy, we performed a(More)
Toll-like receptors (TLRs) play a key role in the innate immune responses to periodontal pathogens in periodontal disease. The present study was performed to determine the roles of TLR2 and TLR4 signaling in alveolar bone resorption, using a Porphyromonas gingivalis-associated ligature-induced periodontitis model in mice. Wild-type (WT), Tlr2(-/-), and(More)
UNLABELLED The mouse double-minute 2 (MDM2) oncogene, amplified or overexpressed in many human cancers, has been suggested to be a novel target for cancer therapy. Visualization of MDM2 expression using radionuclide targeting can provide important diagnostic information in malignant tumors. The overall aim of this study was to evaluate whether(More)
