Although a number of surrogate biomarkers exist for measuring the metabolic products of bone resorption, the serum CTX marker was chosen because it is both highly correlated to bone turnover rate and already available for detection in a laboratory test carried out by a major lab testing corporation. [1]
To determine an individual's rate of bone turnover, numerous biomarkers are available in the body fluids that can be correlated to this rate, and one such biomarker is NTX. [ 1 ] However, while NTX does fluctuate in a very sensitive manner in line with bone resorption patterns, they are not very specific , in that they may vary spontaneously ...
Her DNA was scanned for 210 health markers, and as we saw in other tests, she carries one copy of the gene related to exercise-induced collapse syndrome. You need two copies to be at risk, but I ...
where, is a convolution operator, C bone (t) is the bone tissue activity concentration of tracer (in units: MBq/ml) over a period of time t, C plasma (t) is the plasma concentration of tracer (in units: MBq/ml) over a period of time t, IRF(t) is equal to the sum of exponentials, β values are fixed between 0.0001 sec −1 and 0.1 sec −1 in ...
This swab kit tests for more than 235 diseases and compares your dog's DNA with “the world's largest breed reference database (21,000+ samples from over 50 countries).” The company says test ...
The bone formation portion (σ f) of the bone remodeling period is calculated as follows: [5] = in which MWT refers to the mean wall thickness of the completed bone unit and M f refers to the prevailing mean effective bone appositional rate. In other words, what this formula means is that the bone remodeling period is equivalent to the ...
Osteocalcin, also known as bone gamma-carboxyglutamic acid-containing protein (BGLAP), is a small (49-amino-acid [5]) noncollagenous protein hormone found in bone and dentin, first identified as a calcium-binding protein. [6] Because osteocalcin has gla domains, its synthesis is vitamin K2-dependent. In humans, osteocalcin is encoded by the ...
A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
