1.  Investigation of oxidative balance in patients with dysmenorrhea by multiple serum markers 
Objective:
To investigate the level of oxidative stress in patients with dysmenorrhea by multiple serum markers including malondialdehyde (MDA), nitrotyrosine (3-NT), deoxyguanosine (8-OHdG) and superoxide dismutase (SOD).
Material and Methods:
Fifty-eight women, aged between 20 and 34, who had had regular menses for at least six previous cycles, were involved. The women were divided into two groups. The study group consisted of 33 patients with primary dysmenorrhea, and the control group consisted of 25 healthy women.
Results:
Demographic characteristics of patients were similar between the two groups. The serum MDA levels were 1.32±0.46 and 0.91±0.26 nmol/mL for the dysmenorrhea and control groups, respectively (p<0.001). The differences in plasma levels of 3-NT, SOD and serum 8-OhdG were similar in both groups (p>0.05). Also, no correlation was found between the severity of dysmenorrhea and the levels of oxidative markers.
Conclusion:
Oxidative stress is slightly aggravated in patients with dysmenorrhea.

2.  Uric Acid and Pentraxin-3 Levels Are Independently Associated with Coronary Artery Disease Risk in Patients with Stage 2 and 3 Kidney Disease 
American Journal of Nephrology  2011;33(4):325-331.
Background and Objectives
Cardiovascular disease is prevalent in chronic kidney disease (CKD). Uric acid is increased in subjects with CKD and has been linked with cardiovascular mortality in this population. However, no study has evaluated the relationship of uric acid with angiographically proven coronary artery disease (CAD) in this population. We therefore investigated the link between serum uric acid (SUA) levels and (i) extent of CAD assessed by the Gensini score and (ii) inflammatory parameters, including C-reactive protein (CRP) and pentraxin-3, in patients with mild-to-moderate CKD.
Material and Methods
In an unselected population of 130 patients with estimated glomerular filtration rate (eGFR) between 90 and 30 ml/min/1.73 m2, we measured SUA, serum pentraxin-3, CRP, urinary protein-to-creatinine ratio, lipid parameters and the severity of CAD as assessed by coronary angiography and quantified by the Gensini lesion severity score.
Results
The mean serum values for SUA, pentraxin-3 and CRP in the entire study population were 5.5 ± 1.5 mg/dl, 6.4 ± 3.4 ng/ml and 3.5 ± 2.6 mg/dl, respectively. The Gensini scores significantly correlated in univariate analysis with gender (R = −0.379, p = 0.02), uric acid (R = 0.42, p = 0.001), pentraxin-3 (R = 0.54, p = 0.001), CRP (R = 0.29, p = 0.006) levels, eGFR (R = −0.33, p = 0.02), proteinuria (R = 0.21, p = 0.01), and presence of hypertension (R = 0.37, p = 0.001), but not with smoking status, diabetes mellitus, and lipid parameters. After adjustments for traditional cardiovascular risk factors, only uric acid (R = 0.21, p = 0.02) and pentraxin-3 (R = 0.28, p = 0.01) remained significant predictors of the Gensini score.
Conclusions
SUA and pentraxin-3 levels are independent determinants of severity of CAD in patients with mild-to-moderate CKD. We recommend a clinical trial to determine whether lowering uric acid could prevent progression of CAD in patients with CKD.

3.  The presence of promatrix metalloproteinase-3 and its relation with different categories of coal workers' pneumoconiosis. 
Mediators of Inflammation  2004;13(2):105-109.
Extracellular matrix formation (ECM) and remodeling are critical events related to the pathogenesis of pulmonary fibrosis. Matrix metalloproteinases play an essential role in degrading and remodeling the ECM. In this study, we tried to show the presence and correlation of promatrix metalloproteinase-3 (proMMP-3) (the inactive form of metalloproteinase-3) levels in coal workers' pneumoconiosis (CWP) with different categories. The study population consisted of 44 coal miners with CWP (pos CWP). Coal miners without CWP (neg CWP, n = 24) and non-underground personnel (controls, n = 17) were taken as controls. All coal miners were stable and had no systemic infection or disease. Standard posterio-anterior chest radiographs and pulmonary function tests were performed to exclude any diseases other than CWP. Serum proMMP-3 was analysed using the sandwich enzyme-linked immunosorbent assay according to the manufacturer's instructions (The Binding Site, Birmingham, UK). Mean proMMP-3 values of the all three groups were compared and a significant statistical difference obtained (p < 0.001). In addition, a statistically significant difference was found between categories of the disease and proMMP-3 values (p < 0.05). The effects of age, exposure duration and cigarette smoking on proMMP-3 values in coal miners with CWP were investigated. There were no correlations between age, smoking and proMMP-3 values. However, a positive correlation was found between exposure duration and proMMP-3 values (r = 0.447, p = 0.008). In conclusion, proMMP-3 (prostromelysin 1) may play an essential role in degrading and remodeling the ECM in workers with pneumoconiosis. ProMMP-3 may also reflect the stage of pneumoconiosis disease.
