Biosynthetic human parathyroid hormone (1-34) effects on bone quality in aged ovariectomized rats
For the first time, PTH (1-34) was found to significantly affect bone quality, femora length, and body weight of aged, ovariectomized rats. Specifically, we examined the effects of biosynthetic human PTH (1-34) weiter...
