conclusions the risk of ra increased with delayed menarche, advanced maternal age at first delivery and early age at menopause. however, longer duration of breast-feeding, parity, large number of children and consumption of ocs were found as protective independent variables against ra. methods this case-control study was conducted on 231 patients with ra and 238 controls among females aged 26 -...
Ac-225 has lately drawn considerable attention as a radioisotope for targeted alpha therapy treatment certain types of prostate, blood-derived, and disseminated cancers, but its supply is limited. Therefore, we investigated the production method by nuclear transmutation in fast neutron reactor. The authors irradiation Ra-226 or Th-230 target nuclide experimental reactor Joyo, owned operated Jap...
A 76-year-old man with symptomatic bone metastases from castrationresistant prostate cancer underwent Radium-223-dichloride (Ra-223) therapy. Before Ra-223 therapy, he had normal peripheral blood cell counts. Ra-223 therapy relieved his shoulder and low back pain. The elevation of the serum prostate-specific antigen (PSA), doubling every month during Ra-223 therapy, suggested a PSA flare or rel...
Abstract Background: Rheumatoid Arthritis, (RA) is a chronic inflammatory autoimmune disease with a progressive course requiring early diagnosis and treatment. The value of anti-cyclic citrullinated peptide antibodies (Anti-CCP) in the diagnosis of RA has been shown in several studies. The present study was designed to determine and compare the diagnostic value of Anti-CCP and rheumatoid fac...
BACKGROUND The radiological quality of (226)Ra, (232)Th and (40)K in some samples of water resources collected in Anarak-Khour a desertic area, Iran has been measured by direct gamma ray spectroscopy using high purity germanium detector in this paper. RESULT The concentration ranged from ≤0.5 to 9701 mBq/L for (226)Ra; ≤0.2 to 28215 mBq/L for (232)Th and < MDA to 10332 mBq/L for (40)K. The ra...
Rheumatoid arthritis (RA) is one of the common chronic diseases. Some vegetables and oils may reduce the inflammation in RA and citrus fruits, tomatoes, red meat and salty pickles may worsen the pain and tenderness in joints. The objective of this study is to compare dietary intake of some foods in female RA patients with healthy control group. Materials and Methods: In this case-control study,...
The existence of a Coal - Fired Power Plant (CFPP) is suspected to affect the environment quality, especially increment natural radionuclides content which found in coal as raw material. Therefore, systematic analysis ( 210 Pb, 234 Th, 238 U, 228 RA, 40 K, 226 RA and 232 Th) water, soil , plant were conducted establish data base o f environmental contamination area around CFPP. This research wa...
introduction: dye removal from industrial wastewater has been considered as one of the most environmental issues. recently, new methods of treatment such as catalytic ozonation have been used to increase dye removal efficiency. so, the efficiency of catalytic ozonation by copper coated zeolite as a catalyst in the removal of reactive red 198 was investigated. materials & methods: in order to re...
زمینه و هدف: هستههای پرتوزا به صورت طبیعی و مصنوعی در آب، خاک، سنگ و هوا وجود دارند و همه انسانها در معرض تابشهای هستهای قرار دارند. برخی از فعالیتهای بشری مانند استفاده از سلاحهای حاوی اورانیوم ضعیف شده در جنگها و یا سوانح هستهای باعث افزایش پرتوزایی محیطی میشوند. با توجه به نزدیکی هویزه به مناطق جنگی کشور عراق، مطالعه پرتوزایی خاک این منطقه از اهمیت بالایی برخوردار ...
