BACKGROUND Electrochemotherapy is a local anticancer treatment very efficient for treatment of small cutaneous metastases. The method is now being investigated for large cutaneous recurrences of breast cancer that are often confluent masses of malignant tumour with various degrees of inflammation. To this end 18-Flourine-Flourodeoxyglucose-Positron Emission Tomography/Computed Tomography (FDG-P...
Progesterone, 5-pregnene-3,20-dione, and desoxycorticosterone were found to be partial but significant inhibitors of estrone-induced growth of the uterus of hypophysectomized rats but they did not depress the amount of growth elicited by testosterone. The presence of both the 2-carbon side chain at position 17 and an oxygenated function at position 3 is necessary for the inhibitory activity of ...
دربخش اول این پروژه تحقیقاتی، واکنش تشکیل کمپلکس بین لیگاند درشت مولکول بنزو-15-کرون-5 (b15c5) و کاتیون al3+، در حلال های غیرمائی استونیتریل (an)، متانول (meoh) و پروپانول (proh) و همچنین در مخلوط دوجزئی حلال های غیر آبی استونیتریل-متانول (an-meoh)، استونیتریل-پروپانول(an-proh)، استونیتریل-متیل استات(an-meoac) و استونیتریل- اتیل استات(an-etoac) در دماهای مختلف با استفاده از روش هدایت سنجی مورد ...
Site-specific investigations of the role of radiomics in cancer diagnosis and therapy are emerging. We evaluated the reproducibility of radiomic features extracted from 18 Flourine-fluorodeoxyglucose (18 F-FDG) PET images for three parameters: manual versus computer-aided segmentation methods, gray-level discretization, and PET image reconstruction algorithms. Our cohort consisted of pretreatme...
Background Neurosarcoidosis (NS) is one of the most severe manifestations sarcoidosis [ 1]. NS diagnosis difficult since clinical features and cranial imaging findings are often unspecific central nervous system biopsy unfrequently performed. Flourine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET-CT) emerging as a powerful tool for evaluation sarcoidosis. D...
