Osteoporosis causes bones to weaken and break more easily. Calcium and phosphorus are two minerals that are essential for normal bone formation. Unfortunately, calcium salts commonly presc...
Alendronate is a drug that is used to treat osteoporosis. The purpose of this study is to examine whether alendronate in combination with calcium and vitamin D is safe and effective for tr...
In recent years, vitamin D has been shown not only to be important for bone and calcium metabolism but also for homeostasis of critical tissues involved in vascular disease in patients wit...
The standard recommendation to prevent osteoporosis is to supplement low doses of vitamin D and calcium. Hyperhomocysteinemia has been related to increased risk of osteoporosis.
Patients diagnosed with, or in risk of osteoporosis regularly take calcium dietary supplements, although their contribution to BMD maintenance, prevention of bone loss or reduction of the ...
The antirickets factor vitamin D exhibits its action through activation of vitamin D receptor(VDR). The active form of vitamin D, 1α,25-dihydroxyvitamin D3[1,25(OH)2D3], is a potent VDR ligand, and c...
Vitamin D supplementation is often used in the prevention and treatment of osteoporosis, but the role of vitamin D has lately been questioned. We aimed to investigate the effect of 3 months of daily ...
Osteoporosis is a multifactorial disease with a strong genetic influence. Recent studies have demonstrated that cytokines, such as TGF-β1 and interleukin 6 (IL-6) play complex roles in the normal bon...
Following Roux-en-Y gastric bypass (RYGB), elevated parathyroid hormone (PTH) levels potentially harmful to bone health are commonly observed. Owing to assumed superior absorption, calcium citrate is ...
It is now 100 years since deficiency of vitamin D was identified as the cause of rickets and osteomalacia (see Figure). Since then, enormous amounts of work have been undertaken elucidating the synthe...
Carbonic acid calcium salt (CaCO3). An odorless, tasteless powder or crystal that occurs in nature. It is used therapeutically as a phosphate buffer in hemodialysis patients and as a calcium supplement.
Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (OSTEOPOROSIS, POSTMENOPAUSAL) and age-related or senile osteoporosis.
A field of chemistry which pertains to chemical compounds or ions that do not contain the element carbon (with the exception of carbon dioxide and compounds containing a carbonate radical, e.g., calcium carbonate).
Calcium compounds used as food supplements or in food to supply the body with calcium. Dietary calcium is needed during growth for bone development and for maintenance of skeletal integrity later in life to prevent osteoporosis.
A protein that plays a fundamental role in the Vitamin D mediated transport of calcium in reptiles, amphibians, birds and mammals. It is found in the intestine, kidneys, egg shell gland, brain, and possibly other organs. Its molecular weight is species dependent.
