Since HPVs have been shown to possess oncogenic potential, an association between HPV infection and prostatic cancer (PCa) has been suggested. There are conflicting reports on the impact of HPV infection on the development of prostate cancer.

EBV, which normally has CR2 or CD21 receptors on B-lymphocytes, has mutagenic features for them. The virus plays an important role in causing some malignant cancers. About 30% of the cases with non-Hodgkin’s lymphoma are diffuse large B-cell lymphoma (DLBCL). In the present study, the incidence rate of EBV in DLBCL was evaluated. Materials and Methods: Immunohistochemistry (IHC) and PCR methods were used for studying the relationship between EBV and DLBCL. Paraffin blocks of 116 patients from Sina & Shariati hospitals, Tehran, Iran, with DLBCL diagnoses in 2005-2009 were collected. EBV-LMP in IHC and PCR virus genome in PCR were examined. Results: Findings of the PCR method showed that 28 cases of the total 116 patients with DLBCL were EBV positive (the frequency of EBV positivity was correspondingly 40% and 60% in females and males) and this shows a 25.8% EBV frequency in DLBCL. IHC findings showed that six cases were EBV positive. The compatibility of positive IHC and PCR responses was two cases and there are four conflicting cases.

We evaluated the analytical performance of Accu-check Active (Boehringer Mannheim, Roche) which is one of the most commonly used monitors in Iran. Material and Methods: We compared the monitor readings with the reference values by percentage of values within certain intervals of the reference method, regression analysis, and difference plot. We used operational process specification charts to determine the probability that different QC rules would detect an analytical error. In addition, we assessed the quality on the sigma scale. Results: This meter met International Organization for Standardization’s criteria but not the American Diabetes Association’s stringent criteria. The monitor produced precise readings throughout the concentration range and results correlated closely with the reference method. The measured total error was 6.39% (less than allowable total error of 10%). The method reached 6 sigma at glucose levels of 6.66 and 18.87 mmol/L and a sigma of 3 to 4 at glucose level of 2.49.

Materials and Methods: Levels of interleukin 6 and 8 in cervical samples, collected from 100 pregnant women between 22 to 28 weeks of gestation were measured by ELISA test in Mostafa Khomeini and hazrat-zeinab university hospitals in Tehran, from December 2006 to July 2007. Gestational age at time of delivery was recorded. Receiver operator characteristic curve analysis was used. Results: There were 4.8, and 4.4, -fold increase in cervical interleukin 8 and 6 concentrations in early preterm versus term delivery. A single interleukin 8 >751.25 pg/ml, and l interleukin 6 >157 pg/ml, was identified early preterm versus term delivery.

These methods included E-test MIC, oxacillin screen agar, oacillin disk diffusion, cefoxitin disk diffusion, and CHROMagar- MRSA methods. Results: Out of 294 isolates of S. aureus, one hundred and six (36%) strains of MRSA were isolated from clinical specimen. Oxacillin screen agar and CHROMagar-MRSA showed both 110 MRSA isolates.
