BACKGROUND Second-trimester cell-free fetal DNA (studied only in pregnancies with male fetuses) is higher in maternal serum samples from women carrying Down syndrome fetuses than in unaffected pregnancies. In this study we evaluated the potential performance of fetal DNA as a screening marker for Down syndrome. METHODS Data on maternal serum fetal DNA concentrations and the corresponding conc...
The effect of rhFSH on Sperm DNA Fragmentation and sperm parameters in Oligozoospermia Infertile Men
Background: One of the main causes of male infertility is the negative effects of oxidative stress. Follicle-stimulating hormone (FSH) plays an essential role in spermatogenesis, as well as in the maintenance of sperm DNA integrity. This study aimed to determine whether the recombinant human follicle-stimulating hormone (rhFSH) treatment of sperm parameters could positively affect sperm DNA and...
This study was carried out to identify polymorphisms of BMP15, GDF9 and BMPRIB genes in cross- bred of Romanov×shal sheep. For this reason 79 blood samples were collected from a flock in Gonbad kavous city in Golestan province. DNA was extracted using modified salting out method. Polymerase chain reaction was done by specific primers for amplification of two fragments with 141and 153 bp from ...
