Background: Recent studies have suggested the importance of oxidant/antioxidant status in initiation and progression of breast cancer. The aim of this study was to evaluate oxidative stress markers in breast cancer patients before and after 3 cycles of chemotherapy with adriamycin and cytoxan (AC). Also, in this study the effect of age and the stage of disease on oxidative stress markers were c...

o bjective : increased levels of oxidative stress markers in periodontitis have been reported by recent studies. malondialdehyde (mda) and superoxide dismutase (sod) are both in- creased during oxidative stress. the aim of this study was to detect and measure the level of oxidative stress markers in peri-implant crevicular fluid (picf). their correlation with peri-implant clinical parameters wa...

the aim of this study was to assess the role of hla-b*27 and it’s subtypes in determining severity and clinical manifestations of ankylosing spondylitis (as). a total of 163 as patients were assessed for clinical manifestations and severity using structured questionnaires. hla-b*27 screening and b*27 sub-typing were performed by pcr. one hundred twenty two patients (74.8%) were b*27 positive. t...

 ABSTRACT Background: Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disorder with genetic heterogeneity. Up to three loci are involved in this disease, PKDI on chromosome 16p13.3, PKD2 on 4q21, and a third locus of unknown location. Methods: Here we report the first molecular genetic study of ADPKD and the existence oflocus heterogeneity for ADPKD in the Iranian populatio...

  Background and Objectives: Giant cell Tumor of bone (GCT) is often regarded as a benign tumor, but its clinical course is unpredictable, has a high rate of recurrence, and even can metastases and transform to a malignant tumor. Histological features of the tumor often could not predict its future biologic behavior, so it is just called ''Giant cell tumor'' without indicating maligna...
