Background Matrix metalloproteinase (MMPs) play important roles in the structural and functional properties of reproductive organs. The aim of this study is to determine the prevalence of C-1562T MMP-9 (rs3918242) gene polymorphism in fertile and infertile men. In addition, we aim to determine the association between C-1562T MMP-9 and G-1575A MMP-2 gene polymorphisms. MATERIALS AND METHODS A ...
Apple ( X Borkh.) is one of the world's most valuable fruit crops. Its large size and long juvenile phase make it a particularly promising candidate for marker-assisted selection (MAS). However, advances in MAS in apple have been limited by a lack of phenotype and genotype data from sufficiently large samples. To establish genotype-phenotype relationships and advance MAS in apple, we extracted ...
چکیده: پژوهش حاضر به بررسی تطبیقی اعتماد اجتماعی در بین دبیران زن و مرد مقطع راهنمایی شهر ایلام می پردازد. امروزه در جوامع شاهد گسترش ارتباطات هستیم و با توجه به این که دامنه کنش های اجتماعی از حد روابط با آشنایان و دوستان فراتر رفته و به تعامل با کنشگران غربیه و نا آشنا گسترش یافته است، لزوم وجود اعتماد، بیش از پیش احساس می شود. اما با توجه به نقش دبیران در نهادهای آموزشی، در انتقال ارزش ها و...

this study investigates the effect of teacher’s repetition as an input enhancement technique in explicit teaching of vocabulary items on efl learners’ later retrieval. to this end, 66 persian speaking english learners, aged 18 - 29, homogenized through a standard proficiency test (opt), were chosen and put into two experimental and control groups, each 33 learners. general service list (gsl), a...
rosy apple aphid, dysaphis plantaginea (passerini), with worldwide distribution is an important pest of apple orchards. host plant resistance is an essential component of integrated management of this insect pest. we investigated the resistance of seven apple cultivars, malus domestica (borkhausen), namely granny smith, starkrimson, golden smoothee, red delicious, golden delicious, boshghabi, a...
Infertility is a common problem affecting one in six couples, and in 30% of infertile couples, the male factor is a major cause due to defective sperm quality. P-glycoprotein (P-gp), a product of the MDR1 (ABCB1) gene, may be a link between genetic and environmental factors contributing to the development of male infertility because pesticides (P-gp substrates) are well established factors of m...
Factors affecting the blood-testis barrier function may be involved in testicular damage and male infertility. Two cytokines play an important role in the barrier regulation, namely transforming growth factor beta 3 (TGF-β3) and tumor necrosis factor (TNF-α). The aim of this study was to investigate the potential association between TGF-β3 (TGFB3) and TNF-α (TNF) gene polymorphisms and male inf...
