Objective(s): The aim of this study was to analyze detection rates and effectiveness of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) cancer screening program for prostate cancer in Japan, which is defined as a cancer-screening program for subjects without known cancer. It contains FDG-PET aimed at detection of cancer at an early stage with or without additional screening tests ...
پلی اتیلن ترفتالات (pet) از جمله پلیمرهایی است که در تولید پوشش های ضدمیکروبی کاربرد دارد. این پلیمر خطی بوده و در برابر حلال ها مقاوم می باشد. یکی از روش های ایجاد خاصیت ضد باکتری در محصولات پلی اتیلن ترفتالات تثبیت کیتوزان بر سطح این پلیمر می باشد. تثبیت عامل ضد باکتری با استفاده از پیوندهای کووالانسی بر سطح پلیمر هنگامی ممکن است که هم پلیمر و هم عامل ضد باکتری گروه های عاملی واکنش دهنده با ی...
introduction: the advent of dual-modality pet/ct scanners has revolutionized clinical oncology by improving lesion localization and facilitating treatment planning for radiotherapy. in addition, the use of ct images for ct-based attenuation correction (ctac) decreases the overall scanning time and creates a noise-free attenuation map (6map). ctac methods include scaling, s...
Abstract We study the clustering of Gravitational Wave (GW) merger events and Supernovae IA (SN), as cosmic tracers in Luminosity Distance Space. modify publicly available CAMB code to numerically evaluate auto- cross- power spectra for different sources, including Space distortion effects generated by peculiar velocities lensing convergence. perform a multitracer Fisher analysis forecast expec...
Objective(s): Post-treatment evaluations by CT/MRI (based on the International Working Group/ Cotswolds meeting guidelines) and PET (based on Revised Response Criteria), were examined in terms of progression-free survival (PFS) in patients with malignant lymphoma (ML). Methods: 79 patients, undergoing CT/MRI for the examination of suspected lesions and whole-body PET/CT before and after therapy...
Objective(s): We aim to investigate the clinical impact of 18F-FDG PET/CT in managing patients with gynecological malignancies and pelvic or extrapelvic lymph nodes that are of equivocal significance on conventional imaging.Methods: We retrospectively evaluated 18F-FDG PET/CT scans of patients with gynecologic tumors who were referred to King Hussein Cancer Center from January 2010 to August 20...
in iran, the majority of vegetable oil producers , use pet for packaging their products . due to high solubility of pet oligomers in the oils , and shelf life of liquid oils , it is expected that some compounds migrate into the oil . this study was carried out to determine the amount of migration of terephtalates from pet bottles into sunflower oil and the effect of temperature and storage time...
results thirty-four patients were hyperglycemic and 127 non diabetic. sensitivity, specificity, positive predictive value and negative predictive value of fdg-pet/ct were 90%, 88%, 87% and 91% in non diabetic and 82%, 92%, 95% and 73% in hyperglycemic patients, respectively. overall, the accuracy was higher in non diabetic than hyperglycemic patients (89% vs. 85%). conclusions accuracy of fdg-p...
The degradation of two poly(ethylene terephtalate) (PET) samples from urban and marine wastes (PET-u PET-m, respectively) has been studied by comparing their properties with those virgin PET (PET-v) post-condensed for bottle fabrication (PET-ssp). FTIR spectroscopy, DSC analysis, WCA MFI results have confirmed that all residues were degraded. Therefore, the chemical recycling evaluated in order...
