Abstract
BACKGROUND To determine a cut-off point of tPSA and PSAD to prevent unnecessary invasive cancer-diagnosing tests in the community. METHODS This study was performed on 688 consecutive patients referred to our center due to prostatism, suspicious lesions on digital rectal examination and/or elevated serum PSA levels. All patients underwent transrectal ultrasound guided biopsies and obtained PSAD. Serum levels of tPSA and fPSA were measured by chemiluminescence. Comparisons were done using tests of accuracy (AUC-ROC). RESULTS Prostate cancer was detected in 334 patients, whereas the other 354 patients were suffering from benign prostate diseases. The mean tPSA in case and control groups were 28.32±63.62 ng/ml and 7.14±10.04 ng/ml; the mean f/tPSA ratios were 0.13± 0.21 and 0.26±0.24 in PCa and benign prostate disease groups; the mean PSAD rates were 0.69±2.24, 0.12±0.11, respectively. Statistically significant differences were found (P <0.05). Using ROC curve analysis, it was revealed that AUC was 0.78 for tPSA and 0.80 for f/tPSA. Sensitivity was 71% for the cut-off value of 7.85ng/ml. For f/tPSA ratio, the optimal cut-off value was 0.13 which produced the sensitivity of 81.4% and for PSAD, it was15%. CONCLUSIONS As this trial is different from the European and American values, we should be more cautious in dealing with the prostate cancer upon the obtained sensitivity and specificity for PCa diagnosis (7.85ng/mL for tPSA, 15% for PSAD and 0.13 for f/tPSA ratio).

Abstract
The aim of this study was to investigate the effect of tart cherry juice on serum uric acid levels, hepatic xanthine oxidoreductase activity and two non-invasive biomarkers of oxidative stress (total antioxidant capacity and malondialdehyde concentration), in normal and hyperuricemic rats. Tart cherry juice (5 ml/kg) was given by oral gavage to rats for 2 weeks. Allopurinol (5 mg/kg) was used as a positive control and was also given by oral gavage. Data showed that tart cherry juice treatment did not cause any significant reduction in the serum uric acid levels in normal rats, but significantly reduced (P<0.05) the serum uric acid levels of hyperuricemic rats in a time-dependent manner. Tart cherry juice treatment also inhibited hepatic xanthine oxidase/dehydrogenase activity. Moreover, a significant increase (P<0.05) in serum total antioxidant capacity was observed in tart cherry juice treated-rats in both normal and hyperuricemic groups. The oral administration of tart cherry juice also led to a significant reduction (P<0.05) in MDA concentration in the hyperuricemic rats. Although the hypouricemic effect of allopurinol, as a putative inhibitor of xanthine oxidoreductase, was much higher than that of tart cherry, it could not significantly change anti-oxidative parameters. These features of tart cherry make it an attractive candidate for the prophylactic treatment of hyperuricaemia, particularly if it is to be taken on a long-term basis. Further investigations to define its clinical efficacy would be highly desirable.
