BACKGROUND Cryopreservation of ovarian tissues and pre-antral follicles is a promising prospect for preservation of women fertility. OBJECTIVE The aim of this study was to evaluate the in vitro developmental competence of mouse vitrified pre-antral follicles in comparison to isolated pre-antral follicles derived from vitrified ovaries in the presence of alpha lipoic acid (ALA). MATERIALS AN...

BACKGROUND The objective of this study was to determine whether follicles grown within human ovarian cortical strip culture for 6 days in serum-free medium could be isolated at the secondary stage of pre-antral development and grown in vitro to the late pre-antral/early antral stage during a 4 day culture period. METHODS Ovarian cortical biopsies were obtained from six women aged 26-40 years,...

Methoxychlor (MXC) is an organochlorine pesticide and reproductive toxicant. While in vivo studies indicate that MXC exposure increases antral follicle atresia, in part by altering apoptotic regulators (Bcl-2 and Bax), they do not distinguish whether MXC does so via direct or indirect mechanisms. Therefore, we utilized an in vitro follicle culture system to test the hypothesis that MXC is direc...

cells of primordial, primary, secondary and antral follicles. Connexin 26 expression in antral follicles was decreased by R diet. The expression of Cx43 in granulosa cells of primary and granulosa and theca layers of antral follicles was increased by HSe in M diet. Thus, maternal diet affected Cx26 and Cx43 expression, and connexins may be differentially involved in regulation of fetal ovarian ...

introduction: the horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (psaa) and the infraorbital artery. this anatomic structure is known as the ‘alveolar antral artery’.   materials and methods: we performed a literature review. the anatomic location of the alveolar antral artery in the latera...
