Is liquid nitrogen vapor comparable to liquid nitrogen for storage of cryopreserved human sperm : evidence from the characteristics of post-thaw human sperm?
LN2 vapor was comparable to LN2 in post-thaw sperm characteristics, suggesting that LN2 vapor may be substituted for LN2 for the long-term storage of human sperm.
VDR genotypes are associated with the risk of fracture in postmenopausal women independently of BMD, rate of postmenopausal forearm BMD loss, bone turnover, and endogenous hormones. The mechanisms by which VDR genotypes influence bone strength remain to be determined.
