Progress on the roles of zinc in sperm cryopreservation.

One of the effective methods for the long-term preservation of mammalian genetic resources is the cryopreservation of semen. However, a number of parameters, including diluents, the rate of freezing and thawing, cryoprotectants, etc., can easily alter the survival of frozen-thawed sperm.

1α,25(OH)D Promotes the Autophagy of Porcine Ovarian Granulosa Cells as a Protective Mechanism against ROS through the BNIP3/PINK1 Pathway.

Vitamin D (VD) is one of the important nutrients required by livestock; however, VD deficiency is reported to be widespread. Earlier studies have suggested a potential role for VD in reproduction. Studies on the correlation between VD and sow reproduction are limited.

Expression of ERβ induces bovine ovarian granulosa cell autophagy via the AKT/mTOR pathway.

The aim of our study was to determine whether silencing or overexpression of estrogen receptor β (ERβ) regulates cell proliferation, steroidogenesis, autophagy and signalling pathways in bovine ovarian granulosa cells in vitro. In this study, bovine ovarian granulosa cells (BGCs) were cultured and transfected with ERβ siRNA (si-ERβ) or a plasmid overexpressing ERβ (oe-ERβ), and CCK-8 kit was used to assess cell proliferation. Real-time PCR was used to measure gene transcription.

Function of low back muscle exercise : Preventive effect of refracture analysis of postoperative vertebral fractures.

Background: Low back muscles exercise reportedly influence the risk of osteoporotic vertebral fractures. The exact relationship between the low back muscles exercise and the incidence of vertebral refractures remain unclear.

Objective: To investigate the ability of exercise to strengthen the low back muscles to prevent vertebral refracture after surgery, through clinical analysis of the vertebral fracture risk reduction program.
