background and aim: salivary gland tumors classification continuously undergoes alternations, especially in the recent years. this study used immunohistochemical markers for distinguishing between polymorphous low-grade adenocarcinoma (plga) and adenocarcinoma carcinoma (adcc) which have several overlapping histological and clinical features. materials & methods: ten adcc and eight plga with fi...

Osteosarcoma is the most frequent malignant bone tumor with a peak incidence in the second and third decades of life. Diagnosis of patients with osteosarcoma is limited to clinico-pathological parameters whereas molecular markers of tumor initiation and promotion have not yet been identified. We aimed to study the expression of the anti-apoptotic survivin gene in osteosarcoma specimens. A total...

Gene selection is an important issue in analyzing multiclass microarray data. Among many proposed selection methods, the traditional ANOVA F test statistic has been employed to identify informative genes for both class prediction (classification) and discovery problems. However, the F test statistic assumes an equal variance. This assumption may not be realistic for gene expression data. This p...

Microarray technology has produced a huge body of time-course gene expression data and will continue to produce more. Such gene expression data has been proved useful in genomic disease diagnosis and drug design. The challenge is how to uncover useful information from such data by proper analysis methods such as significance analysis and clustering analysis. Many statistic-based significance an...

i n troduction: cancer is a major cause of mortality in the modern world, and one of the most important health problems in societies. during recent years, research on cancer as a system biology disease is focused on molecular differences between cancer cells and healthy cells. most of the proposed methods for classifying cancer using gene expression data act as black boxes and lack biological i...

il-32 and tnf? are important cytokines in autoimmune and inflammatory diseases. il-32 has not been previously studied with respect to ms. here, we report il-32 and tnf? transcript levels in peripheral blood mononuclear cells of ms patients and control individuals by real time pcr. a significant difference in il-32 and tnf? mrna levels of patients as compared to controls was not observed. howeve...

background resistance exercise is recommended as a useful therapeutic tool for the treatment of type 2 diabetes (t2d); however, the frequency of studies is inadequate to establish the precise mechanisms of any association between them. objectives in this study, we aimed to assess the effect of three months of resistance training on tcf7l2 expression in pancreatic tissues, serum insulin and gluc...
