99MTc-diphosphonate uptake in neuroblastoma

American Journal of Roentgenology, 1976
Marked uptake of 99mTc-diphosphonate was noted in an extraadrenal neuroblastoma. Calcification was not demonstrable on radiographic or light microscopic examination, nor was crystalline material identified on electron microscopic examination; capillaries in the lesion appeared to be intact.

The Orthopaedic Implications of Diphosphonate Therapy

American Academy of Orthopaedic Surgeon, 2010
Diphosphonates are among the many commonly prescribed drugs for osteoporosis management. These synthetic analogues of physiologically occurring inorganic pyrophosphate bind to the hydroxyapatite crystals of bone. Diphosphonates act by decreasing the amount of osteoclast-mediated bone resorption by inducing apoptosis and disrupting the mevalonate ...

Metal-controlled assembly of uranyl diphosphonates toward the design of functional uranyl nanotubules.

Inorganic Chemistry, 2011
Two uranyl nanotubules with elliptical cross sections were synthesized in high yield from complex and large oxoanions using hydrothermal reactions of uranyl salts with 1,4-benzenebisphosphonic acid or 4,4'-biphenylenbisphosphonic acid and Cs(+) or Rb ...
