BACKGROUND AND OBJECTIVE The overexpression of gelatinases, that is, matrix metalloproteinase MMP2 and MMP9, has been associated with tumor progression, invasion, and metastasis. To image MMP2 in tumors, we developed a novel ligand termed [18F]AlF-NOTA-C6, with consideration that: c(KAHWGFTLD)NH2 (herein, C6) is a selective gelatinase inhibitor; Cy5.5-C6 has been visualized in many in vivo tumo...
Using the fixed point method, we prove the generalized HyersUlam stability of the following cubic-quartic functional equation f(2x+ y) + f(2x− y) = 3f(x+ y) + f(−x− y) + 3f(x− y) + f(y − x) (0.1) + 18f(x) + 6f(−x)− 3f(y)− 3f(−y) in fuzzy Banach spaces.
Pediatric lymphomas (PL) are the third most common malignancy and account for 10% to 15% of all cancers in the pediatric age group. Accurate classification and staging are important for appropriate prognosis and treatment of pediatric Hodgkin’s lymphoma (PHL) and non-Hodgkin’s lymphomas (PNHL) and impact patient prognosis significantly. The role of fluorine-18-fluorodeoxyglucose positron emissi...
BACKGROUND F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) is increasingly used for the initial staging and restaging of lung cancer. Incidental gastrointestinal findings are often observed on (18)F-FDG PET/CT. The objective of this study was to assess incidental 18F-FDG uptake by the gastrointestinal tract (GIT) in patients with lung cancer. METHODS Two...
PURPOSE Neoadjuvant therapy is associated with considerable toxicity and limited survival benefits in patients with soft tissue sarcoma (STS). We prospectively evaluated whether 2[18F]fluoro-2-deoxy-d-glucose ((18)F-FDG)-PET/computed tomographic (CT) imaging after the initial cycle of neoadjuvant therapy could predict overall survival in these patients. EXPERIMENTAL DESIGN Thirty-nine patient...
OBJECTIVE To investigate the diagnostic value of 18F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) in the assessment of myocardial viability in patients with known coronary artery disease (CAD) when compared to (99m)Tc single photon emission computed tomography (SPECT) and echocardiography, with invasive coronary angiography as the gold standard. METHODS Thirty patients with...
INTRODUCTION In this study, the influence of physiological determinants on 18F-fluoro-d-glucose ((18)F-FDG) brain uptake was evaluated in a mouse model of Alzheimer disease. MATERIALS AND METHODS TASTPM (Tg) and age-matched C57BL/6 J (WT) mice were fasted for 10 hours, while another group was fasted for 20 hours to evaluate the effect of fasting duration. The effect of repeatedly scanning was...
