Background: Endometrial carcinoma is the most common malignancy of the female genital tract. Different molecular alterations have been described in endometrioid endometrial carcinoma that, the most frequently altered gene is mutations of PTEN. Up to 50-83% of endometrioid carcinoma reveal altered PTEN characterized by loss of expression. In endometrial hyperplasia, which are precursors of endom...
Introduction: Complex molecular pathways involve in development of different tissues such as teeth. Differential gene expression patterns during teeth development generates different tooth types. Teeth development results from interactions between oral epithelium and underlying ectomesenchyme cells with neural crest origin. Teeth development are regulated by different signaling networks. In thi...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
Background and Objective: To evaluate interaction of salvigenin with DNA and the molecular mechanism of its anti-cancer effect. Materials and Methods: Salvigenin from Tanacetum canescens and DNA from calf thymus were isolated and purified. Then, salvigenin interaction with DNA in Tris buffer (0.05 M, pH equal to 4.7 and the temperature at 25 °C) was studied by different methods. Results and Con...
detection and identification of leishmania parasites within sand flies using kdna, rdna and cpb loci
objective: molecular epidemiology of visceral leishmaniasis (vl) is currently used widely for different objectives such as vector incrimination studies. materials and methods: in this study three different loci including kinetoplast dna (kdna), ribosomal dna (rdna), and cystein protease b (cpb) of leishmania parasite genome were used for detection and identification of natural infection of san...
