Effect of circulating anti-Mullerian hormone on the reproductive potential of gilts.

Introduction: Determination of the ovarian follicular reserve is of great value for predicting fertility, while circulating anti-Müllerian hormone (AMH) plays an important role in maintaining the ovarian reserve.

Methods: In this study, we examined the effect of circulating AMH levels of gilts between 110 and 160 days of age on reproductive performance and evaluated the differences in the ovaries and uteruses of gilts with different AMH levels.

Results: The results indicated a significant negative correlation between circulating AMH levels from days 110 to 160 and puberty ( < 0.

Rutin enhances mitochondrial function and improves the developmental potential of vitrified ovine GV-stage oocyte.

Vitrification of oocyte has become an important component of assisted reproductive technology and has important implications for animal reproduction and the preservation of biodiversity. However, vitrification adversely affects mitochondrial function and oocyte developmental potential, mainly because of oxidative damage. Rutin is a highly effective antioxidant, but no information is available to the effect of rutin on the mitochondrial function and development in vitrified oocytes.

SIRT2 regulates apoptosis by inducing mitophagy in sheep cumulus cells.

Cumulus cells surrounding oocytes furnish nutritional support crucial for oocyte maturation in vitro, and thereby enhance oocyte quality significantly. Our previous studies affirmed the role of SIRT2 in regulation of mitochondrial function in sheep granulosa cells. However, the effect of SIRT2 action on mitophagy in these cells remain unclear.

[National survey of urban sewage reuse in China].

On the basis of the national survey of the urban sewage treatment, the survey of 2007 national urban sewage reuse was conducted under the charge of the Ministry of Water Resources. The survey results indicated that the amount of urban sewage reuse was 17.9 x 10(8) m3 x a(-1), mainly used for industry, landscape, agriculture forestry, animal husbandry, urban non-potable water, and groundwater recharge.
