The aims of the present study were to assess the effects of cysteamine as an anti-oxidant on the rate of in vitro maturation (IVM) of buffalo oocytes (experiment 1), and their viability and nuclear status following vitrification (experiment 2). Immature oocytes with compact cumulus cells obtained from the ovaries of slaughtered animals were harvested and then cultured in the maturation medium w...
Purpose: Melatonin promotes in-vitro embryo development in different species. This study studied the effects of melatonin on in-vitro mouse preimplantation embryo development. Materials and Methods: Two-cell embryos were obtained from oviduct of 6-8 weeks female NMRI mice 48 hours after administration of an intra-peritoneal injection of 5 IU/ml pregnant mares’ serum gonadotrophin and subsequent...
Background and Objective: In recent years, the biological methods have been considered as a most promising candidate for the cancer treatment. One of the most applicable methods is recombinant proteins. ONTAK immunotoxin is a special drug for cancer therapy of leukemia, lymphoma and melanoma. With respect to the dramatic growth of cancer in today's society, production of recombinant prot...
Nutrient enrichment in water and sediments due to excessive anthropogenic activities in recent years has caused excessive algal growth in the Caspian Sea. The current study was conducted to determine the abundance of phytoplankton community, the dominant species and chlorophyll-a [Chl-a] concentration during algal blooms in the Iranian coastal waters of Caspian Sea through four seasons from 201...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
