Cumulus cell expansion and ultrastructural changes in in vitro matured bovine oocytes under heat stress
Cumulus-oocyte complexes (COCs) from cows were matured under normal (38.5°C) and elevated temperatures (41°C) simulating heat stress and their maturation was assessed based on measurement of cumulus expansion in both groups. There was a significant reduction (P

15 صفحه اولUltrastructural Changes of Sheep Oocytes Follow Vitrification by Different Methods and In Vitro Maturation
Purpose: Our aim was determination of the sheep oocytes ultrastructural changes follow vitrification and in vitro maturation. Materials and Methods: Good quality isolated cumulus-oocyte complexes (COCs) were randomly divided into non-vitrified control, conventional straw, cryotop and solid surface vitrification groups. In the conventional and cryotop methods the vitrified COCs were plunged dire...
متن کاملUltrastructural changes in oocytes during folliculogenesis in domestic mammals
The ultrastructural analysis of oocytes and ovarian follicles has been used to evaluate the effects of assisted reproductive techniques, such as cryopreservation or in vitro oocyte maturation. It also benefits the understanding of such complex mechanisms that occur during folliculogenesis. From the beginning of primordial follicles growth until oocyte maturation in preovulatory follicles oocyte...
متن کاملUltrastructural changes in gastric ulcers after bicitropeptide and cimetidine treatment.
Ultrastructural studies were conducted on biopsy specimens taken by endoscopy from the edge of gastric ulcers in the distal part of the stomach of 9 patients before and after treatment with either bicitropeptide or cimetidine. Marked depletion of mucin granules in the mucous epithelial cells and the pyloric gland cells was found in all patients and there was morphological evidence of a block in...
