Infection of farm by this pathogen can result in huge damage around the world. Development of resistant varieties is the most effective method for disease control. Four races of 0, 1, 2 and 1,2 have be...
ویروس y سیب زمینی (potato virus y; pvy) یکی از عوامل مهم تأثیر گذار بر روی کیفیت و عملکرد توتون (nicotiana tabacum l.) می باشد. نشانگرهای مولکولی مبتنی بر dna ابزار ارزشمندی برای به-نژادی گیاهان و انتخاب به کمک نشانگر (marker assisted selection: mas) برای مقاومت به آفات و بیماری ها و برخی صفات مطلوب هستند. در این مطالعه تنوع ژنتیکی 27 ژنوتیپ شرقی و نیمه شرقی توتون با 28 جفت آغازگر ssr بررسی گرد...
Background: A significant percent of infertile varicocele patients remained infertile after varicocelectomy and finally most of them refer for assisted reproductive technique (ART) procedures as intra uterine insemination (IUI), in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). In order to achieve the best results, more strict and accurate standards for ...
Background Sperm preparation before assisted reproductive techniques is very important for obtaining successful fertilization and pregnancy. During ICSI technique, sperms are selected based on viability and morphology. But this selection did not guarantee integrity of sperm DNA. Therefore, novel sperm selection procedures are introduced for selection of sperm with low DNA damage. One of these p...
BACKGROUND AND PURPOSE Cost in healthcare is an increasing and justifiable concern that impacts decisions about the introduction of new devices such as the da Vinci(®) surgical robot. Because equipment expenses represent only a portion of overall medical costs, we set out to make more specific cost comparisons between open and robot-assisted laparoscopic surgery.
