View clinical trials related to Bone Resorption.
Filter by:Lead accumulates in bone. During pregnancy, physiologic changes occur prompting bone resorption in order to provide calcium to the growing fetal skeleton also release the lead stored in bone into a pregnant woman's circulation. We have previously demonstrated that lead stores mobilized into the circulation of pregnant women pose a major threat to fetal development. This is particularly unfortunate since bone lead stores, once accumulated, persist for decades, thereby jeopardizing the pregnancies of women even if their current lead exposures have subsided. What then can be done for the many thousands of women who have had lead exposure while growing up and who want to have healthy children? To address this question, in 2000, this project embarked on a randomized intervention trial to test whether a bedtime nutritional supplement of 1,000 mg of calcium can significantly reduce fetal lead exposure and toxicity by suppressing bone resorption in the pregnant mother.
Women and men consuming a low protein diet may be at risk for bone loss. The purpose of this study is to determine whether a daily protein supplement will improve bone health among healthy older adults.
The purpose of this study is to compare the effectiveness and safety of zoledronic acid with alendronate in the prevention of bone loss after organ transplantation. Zoledronic acid is given as a single intravenous infusion. Alendronate is given as a weekly pill. Both are expected to be very effective, but it is not known which one will work best.
The purpose of this research study is to evaluate the usefulness of the TRAP protein as (1) an early indicator of bone destruction and (2) a tool for assessing the effect of Zometa® in treating symptoms of bone metastases due to breast cancer. Tartrate-resistant acid phosphatase (TRAP) is a protein released into the blood stream as a result of bone destruction caused by metastasis of breast cancer to the bone. Bone destruction causes pain and bone fractures. This study will measure TRAP levels in serum taken from breast cancer patients to see if TRAP levels will be able to predict the effect of Zometa® treatment on bone destruction, pain and bone fractures.
The objective of the study is to investigate whether blood markers can be used to predict the development of bone metastases and to assess the efficacy and safety of zoledronic acid in cancer treatment induced bone loss.
