Abnormalities of bone mineral metabolism and vascular calcification are prevalent in patients with kidney failure. Clinical management is based on biochemical targets, in particular parathyroid hormone (PTH) concentrations, but this has many limitations including high biological variation. A possible alternative is bone-specific alkaline phosphatase (ALP); therefore, we evaluated the biological...
INTRODUCTION Prolonged treatment with levothyroxine 4 (L-T4) is a well known risk factor for osteoporosis. Patients on L-T4 replacement occasionally have a subnormal TSH, which carries a risk of development of bone loss. Thyroid hormones directly affect bone cells, stimulating osteoclastic and osteoblastic activity with a predominance of bone resorption and decrease of bone mineral density (BMD...
Objective Bone demineralization is common in HIV-infected subjects. Reliable and low cost methods would be useful in order to identify and monitor bone alterations both in older and younger HIV+ patients. Recent data in normal population suggest that bone mineral quality (BMQ), assessed by a quantitative ultrasound (QUS) technique, could be an early marker of osteopenia/osteoporosis. Therefore,...
BACKGROUND Damages to large arteries are related to bone disease in end-stage renal disease and contribute to cardiovascular mortality. An outward remodeling and stiffening of carotid artery already exist at an earlier stage of chronic kidney disease (CKD). We made the hypothesis that bone disease could be associated with the carotid outward remodeling in parallel with the decline of renal func...
The important role of ephrinB2-EphB4 signaling pathway in bone remodeling has been well established. However, it is still unclear whether this bidirectional signaling also has effects on the regenerative processes of bone defects created in an inflammatory microenvironment. In this study, an experimental animal model of bone defects treated with lentiviruses was prepared and an inflammatory mic...
An ideal battery of tests would include indices of bone resorption and formation. They should be unique to bone, reflect total skeletal activity, and should correlate with traditional measures of bone remodeling activity, such as radiocalcium kinetics, histomorphometry, or changes in bone mass. Factors that confound their measurement, such as circadian rhythms, diet, age, sex, bone mass, liver ...
Wheat germ agglutinin (WGA) precipitates bone type serum alkaline phosphatase (sALP) isoenzyme specifically. The precipitates are composed of the macromolecules of WGA and "bone type sALP" (WGA-ALP complex). In order to use bone type sALP as a marker in polyacrylamide gel electrophoresis (PAGE), a method to separate "bone type sALP" from the "WGA-ALP complex" was established by using N-acetyl-D...
