The present study is conducted, in order to contribute to a future waste management policy related to the presence of technologically enhanced natural occurring radioactive material (TENORM) in Iran petroleum industry. Samples were collected from offshore oil company for analysis of 238U, 235U, and 232Th series in produced waters. The activities of samples were determined by high-purity germanium detector, well for lowlevel activity γ-spectrometry. The results have shown that, 226Ra concentration ranges from 5.26 Bq/L to 27.93 Bq/L. Also the total activity in produced water is in the range of 16–840 Bq/L were mainly due to enhanced levels of dissolved 226Ra, 214Pb, 214Bi ions. Also, enhanced dissolution of elements such as radium by increasing of salinity, result in higher concentration of NORM in old oil region. Measured values are above EPA regulation (40 CFR 141055) & aqueous Derived Release Limit (DRL) of Canadian guideline for the management of (NORM). Therefore produced water has to dispose in pits which have to design for decrease the environmental effects. Also according to this study, re-injection of produced water in to abandon well of Iran Offshore Oil Company in Persian Gulf, have preference over discharging to the pits.

Atherosclerosis is an inflammatory disease causing a vast array of cardiovascular diseases. Adipophilin has been reported to be highly expressed in atherosclerotic lesions. This study investigated the possible existence of auto-reactive T cells against an HLA-A02-restricted adipophilin-derived peptide as well as peptides from Epstein-barr virus (EBV), Cytomegalovirus (CMV) and influenza (Flu) virus in patients with atherosclerosis.


HLA-A02 expression on peripheral blood mononuclear cells (PBMCs) was examined by flow cytometry. PBMCs from HLA-A02 individuals were stimulated with adipophilin, CMV, EBV, and Flu peptides at a concentration of 10 µM. Interferon (IFN)-γ production was evaluated in the culture supernatant using a commercial ELISA test.


The levels of IFN-γ production against an HLA-A02-restricted adipophilin peptide and peptides from CMV, EBV, and Flu revealed no statistically significant differences between patients and healthy controls. However, we found a positive correlation between IFN-γ production against adipophilin and Body mass index (BMI) of patients (R = 0.8, P = 0.003), whereas no significant correlation was found in healthy controls (R = −0.267, P = 0.378). No correlation between BMI and IFN-γ production against CMV, EBV, or Flu peptides was found.


Atherosclerotic patients with higher BMIs might have greater numbers of T cells against adipophilin that is highly expressed in atherosclerotic plaques. Therefore, autoimmune reactions may have a greater role in the development of atherosclerosis in individuals with higher BMI.
