Calcium Pyrophosphate
An inorganic pyrophosphate which affects calcium metabolism in mammals. Abnormalities in its metabolism occur in some human diseases, notably HYPOPHOSPHATASIA and pseudogout (CHONDROCALCINOSIS).

Tetramisole
Tetramisole is a pharmaceutical compound, specifically an anthelmintic drug, used in the treatment of parasitic worm infestations, with the two enantiomers having different therapeutic uses: levamisole as an immunomodulator and to treat certain gastrointestinal parasites, while racemic tetramisole is used as a livestock dewormer.
Joint Diseases
'Joint diseases' is a broad term that refers to medical conditions causing inflammation, degeneration, or functional impairment in any part of a joint, including the cartilage, bone, ligament, tendon, or bursa, thereby affecting movement and potentially causing pain, stiffness, deformity, or reduced range of motion.
Osteoarthritis
A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.

Arthritis
Arthritis is a general term used to describe inflammation in the joints, often resulting in pain, stiffness, and reduced mobility, which can be caused by various conditions such as osteoarthritis, rheumatoid arthritis, gout, or lupus.
Hydroxyapatites
A group of compounds with the general formula M10(PO4)6(OH)2, where M is barium, strontium, or calcium. The compounds are the principal mineral in phosphorite deposits, biological tissue, human bones, and teeth. They are also used as an anticaking agent and polymer catalysts.

Technetium Tc 99m Pyrophosphate
A radionuclide imaging agent used primarily in scintigraphy or tomography of the heart to evaluate the extent of the necrotic myocardial process. It has also been used in noninvasive tests for the distribution of organ involvement in different types of amyloidosis and for the evaluation of muscle necrosis in the extremities.
Calcium Signaling
Signal transduction mechanisms whereby calcium mobilization (from outside the cell or from intracellular storage pools) to the cytoplasm is triggered by external stimuli. Calcium signals are often seen to propagate as waves, oscillations, spikes, sparks, or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.
