Analysis of chromatin integrity and DNA damage of buffalo spermatozoa
This study was conducted to determine chromatin integrity and DNA damage by DNA electrophoresis and comet assays of buffalo fresh and frozen semen. Semen samples were collected from four buffalo bulls and evaluated after freezing for semen motility, viability, sperm abnormalities, chromatin integrity and DNA damage. A significant variation was found in semen parameters after thawing. Highly sig...

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اولP-134: In Vitro Assessment of Cysteine Effect on DNA Integrity of Frozen-Thawed Buffalo Spermatozoa
Background: Cysteine has been used as additive in cryopreservation extenders. It contains of thiol group which plays an antioxidant role to eliminate reactive oxygen species (ROS) during freeze -thaw procedure. Excessive ROS production cause DNA damage and subsequently reduce sperm fertility. On the other hand, protamine protein have high levels of cysteine which is critical in packaging and co...
متن کاملInvestigation of fertilizing capacity of cryopreserved spermatozoa from patients with cancer.
PURPOSE There are few published reports concerning fertilization and pregnancy outcomes achieved with cryopreserved spermatozoa from cancer patients. Controversy exists regarding the value of sperm banking for these patients before therapy, whether the spermatozoa are viable after long-term storage and whether they can fertilize the ovum. We assess fertilization and pregnancy outcomes achieved ...
