Fetal nucleated erythrocytes circulating in maternal blood are a potential source of fetal DNA for noninvasive prenatal genetic diagnosis. However, the estimated ratio of fetal to maternal cells is extremely small. In order to enrich these cells, we performed direct culture using a two-phase liquid system. Mononuclear cells were obtained from maternal blood samples at 8-10(+3) weeks of gestatio...
Ophiocordyceps sinensis is a well-known entomogenous and medicinal fungus. After its anamorphs parasitize the larvae of the genus Thitarodes, fruit-bodies may form to be used as medicine. However, its developmental mechanisms remain unknown. The distribution of O. sinensis was determined in different tissues of the Thitarodes larvae and the dominant plant species using real-time quantitative po...
This protocol describes a method for the microdissection of Drosophila polytene chromosomes. The microdissected DNA can be amplified by degenerate oligonucleotide primed-polymerase chain reaction (DOP-PCR) and then used to prepare probes for fluorescent in situ hybridization (FISH).
این آزمایش به منظور تعیین ترکیب شیمیایی و تجزیه پذیری 12 واریته دانه غلات (6 واریته گندم، 3 واریته ذرت و 3 واریته ارزن) به روش in situ به اجرا درآمد. در این آزمایش از 6 راس گوسفند نائینی با وزن متوسط 40 کیلوگرم استفاده شد. دانه های اسیاب شده(2 میلیمتر) در زمانهای 0 ، 2 ، 4 ، 8 ، 12 و 24 درون شکمبه قرار گرفتند. اثرات غله ها و واریته های هر غله در قالب طرح کاملا" تصادفی آنالیز شد و جهت بررسی اثرا...
Background:Breast cancer remains the most common and second lethal cancer in females. HER-2/neu is one of the most important amplified oncogene in breast cancer. The amplification of HER-2 is correlated with decreased survival, metastasis, and early recurrence. The amplification of HER-2/neu gene and synthesis of th...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
