Abstract
Background: Cardiovascular diseases, especially atherosclerosis, are the main causes of morbidity and mortality worldwide. The disease has had an increasing prevalence in Iran in recent years. Homocysteine and C-reactive protein (CRP) are two novel cardiovascular risk factors that independently predict risks of atherosclerosis. The purpose of this study was to investigate the effects of one session of circuit resistance training on the blood levels of the aforesaid inflammatory markers in inactive middle- aged men. Methods: The participants of this study included twenty-three healthy but inactive middle-aged men who were overweight and were randomly divided into two experimental (n=14) and control (n=9) groups. The activity included doing exercises with the subjects’ 35% one-repetition maximum (1-RM) intensity at ten different stations. Blood levels of homocysteine and hs-CRP were measured before and after the exercise. Results: Analysis of data using independent samples t-test showed a significant increment in the serum levels of homocysteine and hs-CRP after training in the experimental (P<0.05) versus the control group. Conclusion: Elevation of homocysteine levels is due to the increase in protein metabolism and creatine synthesis for energy production and elevation of hs-CRP levels could be due to hepatic induction of interleukin-6 that acts as a signal for the stimulation of lipolysis and glycogenolysis. However, beneficial or adverse physiological effects of these changes are not thoroughly understood and more research is needed to conclude about the acute and chronic effects of different types of physical activity on the blood levels of these atherosclerosis risk factors.

Abstract
Background: Pleural effusion is the accumulation of fluid in the pleural cavities resulting from an imbalance of fluid production and reabsorption. Early detection of the cause of pleural effusion leads to early treatment and reduces effects on the patient. The most important step in pleural effusion diagnosis is to determine its nature and to determine whether it is transudate or exudate. CRP(C-reactive protein) is an acute-phase protein that is synthesized by hepatocytes during inflammatory states, the highly sensitive type of CRP is more sensitive than the standard CRP test and measures lower levels. It may help differentiate the nature of pleural effusion. The aim of this research was to evaluate the hs-CRP diagnostic value in differentiating the nature of the pleural effusion
Methods: In this descriptive-analytical cross-sectional study, in Rohani hospital of Babol from March 2017 to February 2019, 75 pleural effusion patients, undergoing thoracentesis, the hs-CRP level was measured in their pleural fluid and were compared based on Light´s criteria in two groups of transudates and exudates. Using the ROC curve, the appropriate cut-off point was determined for hs-CRP to differentiate the nature of pleural effusion.
Results: Out of 75 patients, 45 patients were in the exudative pleural effusion group and 30 patients in the transudative group. The mean of hs-CRP in the exudate group was 18.27±10.74 mg/L and in the transudative group 2.98±2.15 mg/L (p˂0.001). The cut-off point for hs-CRP of pleural fluid was calculated to be 5.94 mg / L, which has a sensitivity of 88.9% and a specificity of 93.3%. This marker was also studied in exudative subgroups, and there was a significant difference between pleural hs-CRP levels in two groups of pleural effusion due to malignancy and Parapneumonic effusion (p=0.011).
Conclusion: The pleural fluid hs-CRP can be used as a useful marker for differentiating the nature of pleural effusion and differentiating the pleural effusion of transudate and exudate.
