BACKGROUND A severe form of iron overload with the clinicopathological features of haemochromatosis inherited in an autosomal dominant manner has been described in the Solomon Islands. The genetic basis of the disorder has not been identified. The disorder has similarities to type 4 haemochromatosis, which is caused by mutations in ferroportin1. AIMS The aims of this study were to identify th...
background: in the era of well-developed site-specific treatment strategies in cancer, identification of occult primary is of paramount importance in cup patients. furthermore, exact determination of the extent of the disease may help in optimizing treatment planning. the aim of the present study was to investigate additional value of f-18 fdg pet/ct in patients with cancer of unknown primary (...
Dyeing properties of compounded polyethylene terephthalate fibers with a polyesteramide hyperbranched polymer were investigated in terms of their thermodynamic parameters, including standard affinity -Δμ⁰, enthalpy change ΔH⁰ and entropy change ΔS⁰. Results were then compared with corresponding properties of the virgin PET. The results showed that the isotherms were similar to that of virgin PE...
آمیزه کاری روشی اقتصادی و مناسب برای دستیابی به مواد جدید با خواص بهینه می باشد. در این میان، آمیزه های امتزاج ناپذیر با توجه به برهمکنشهای پلیمر-پلیمر، سینتیک فرایند اختلاط و برخورداری از خواص مفید و مطلوب هر جزء به آمیزه های امتزاج پذیر ترجیح داده می شوند. در صنایع مربوط به الیاف بشر ساخت به منظور بهبود خواص الیاف و برطرف نمودن نقاط ضعف آنها، از آمیزه های پلیمری استفاده می شود. در این تحقیق، ...
Background: In the treatment of bronchial asthma, the identification, isolation, and elimination of causative allergens is the most effective part of treatment. With the recent diversification within the pet industry, pet owner exposure to many unknown antigens is on the rise. The results of population studies have been contradictory and some epidemiological studies have failed to confirm this,...
the advent of dual-modality pet/ct imaging has revolutionized the practice of clinical oncology, cardiology and neurology by improving lesions localization and the possibility of accurate quantitative analysis. in addition, the use of ct images for ct-based attenuation correction (ctac) allows to decrease the overall scanning time and to create a noise-free attenuation map (μmap). the near simu...
Objective(s): 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET-CT) is a well-used and established technique for lung cancer staging. Radiation therapy requires accurate target volume delineation, which is difficult in most cases due to coexisting atelectasis. The present study was performed to compare the 18F-FDG PET-CT with contrast enhanced computed tomogr...
Objective(s): 18F-fluciclovine (trans-1-amino-3-[18F] fluorocyclobutanecarboxylic acid, [FACBC]) is an artificial amino acid radiotracer used for positron emission tomography (PET) studies, which is metabolically stable in vivo and has a long half-life. It has already been shown that FACBC-PET is useful for glioma imaging. However, there have been no reports evaluating the efficiency of FACBC-P...
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 ...
