Vitamin K catabolite inhibition of ovariectomy-induced bone loss: Structure–activity relationship considerations [PDF]

, 2014
The potential benefit of vitamin K as a therapeutic in osteoporosis is controversial and the vitamin K regimen being used clinically (45 mg/day) employs doses that are many times higher than required to ensure maximal gamma‐carboxylation of the vitamin K‐

Conclusions of the French Food Safety Agency on the toxicity of bisphenol A [PDF]

, 2011
Since more than 10 years, risk assessment of bisphenol A (BPA) is debated at the international level. In 2008, the U.S. National Toxicology Program (NTP) expressed some concern for adverse effects, at current level of exposure to BPA, on developmental ...

Mechanical behavior of osteoporotic bone at sub-lamellar length scales [PDF]

, 2015
Osteoporosis is a disease known to promote bone fragility but the effect on the mechanical properties of bone material, which is independent of geometric effects, is particularly unclear.

The "Ram Effect": A "Non-Classical" Mechanism for Inducing LH Surges in Sheep [PDF]

, 2016
During spring sheep do not normally ovulate but exposure to a ram can induce ovulation. In some ewes an LH surge is induced immediately after exposure to a ram thus raising questions about the control of this precocious LH surge.

Characteristics of an ovariectomized osteopenic rat model

Journal of Bone and Mineral Research, 1989
Abstract Although osteoporosis induced by ovariectomy (Ovx) in the rat has been widely used as a model for postmenopausal osteoporosis in humans, the findings of different investigators are not always consistent. This might be mainly due to differences in the age of the animals at Ovx, time after Ovx, and the variables measured ...

Estrogenic effects of silymarin in ovariectomized rats [PDF]

Veterinární medicína, 2001
The objective of this study was to test whether silymarin induces changes indicative of estrogenic effects in gonadal organs of ovariectomized (OVX) rats. Silymarin was administered in two experimental groups of OVX rats (n = 7 + 7) for 30 days at the doses of 25 or 50 mg per animal per day. OVX rats (n = 7) receiving 5 µg of 17b-estradiol (E2) for the
