Lymphocyte-predominant breast cancer (LPBC) defined by the density of stromal lymphocytes shows favorable behavior. However, considerable distribution heterogeneity of lymphocytes is a major problem. The present study defined LPBC by the proportion of lymphocyte-rich stroma with the cut-off values of 30, 50, and 75%, and clinicopathologically analyzed mainly LPBC (area > 30%) defined by the cut...
Background Radiolabeled prostate-specific membrane antigen (PSMA) has proven to be a highly accurate method to detect recurrence and metastases of prostate cancer, but only sparse data is available about its performance in the diagnosis of clinically significant primary prostate cancer. Methods We compared 68Ga-PSMA-11 PET/CT in 25 patients with 18FEC PET/CT in 40 patients with suspected pros...
In this paper, we introduce and analyze a new cut-off priority scheme which provides a better grade-of-service to handoff traffic while maintaining high throughput for the originating calls. A hysteresis control is used for additional robustness. The system model is found to have a general level dependent Quasi-Birthand-Death (QBD) structure. An efficient solution methodology is used taking ful...
مقدمه : تشخیص انفارکتوس میوکارد تا حد زیادی بستگی به مارکرهای بیوشیمیایی دارد. هدف این مطالعه بررسی حساسیت و ویژگی فعالیت ck-mb در تشخیص انفــارکتوس میوکارد می باشد. با توجه به اینکه در کتب رفرنس توصیه شده است هر آزمایشــگاهی cut off تشخیصــی خود را با توجه به تفــاوت هایی که در شرایط آزمایشگاه و جمعیت منطقه وجود دارد تعیین کند و فعــالیت ck-mb از اسفند ماه 81 در بیمارستان حضرت ولی عصر (عج) اند...
background: one of the methods used for standard setting is the borderline regression method (brm). this study aims to assess the reliability of brm when the pass-fail standard in an objective structured clinical examination (osce) was calculated by averaging the brm standards obtained for each station separately. materials and methods: in nine stations of the osce with direct observation the e...
Background: Prostate cancer has been reported as a worldwide important kind of cancer and the second most common cause of cancer-related mortality among men. Prostate-specific antigen (PSA) serum level is one of the most important markers of prostate cancer diagnosis. While PSA level helps predict the risk of prostate cancer development, researchers still looking for ways to increase the accura...
