cal·ci·um

 (kăl′sē-əm)
n. Symbol Ca
A silvery, moderately hard alkaline-earth metal that constitutes approximately 3.6 percent of the earth's crust and is a basic component of most animals and plants. It occurs naturally in limestone, gypsum, and fluorite, and its compounds are used to make plaster, quicklime, Portland cement, and metallurgic and electronic materials. Atomic number 20; atomic weight 40.08; melting point 842°C; boiling point 1,484°C; specific gravity 1.54; valence 2. See Periodic Table.

[Latin calx, calc-, lime; see calx + -ium.]

calcium

(ˈkælsɪəm)
n
(Elements & Compounds) a malleable silvery-white metallic element of the alkaline earth group; the fifth most abundant element in the earth's crust (3.6 per cent), occurring esp as forms of calcium carbonate. It is an essential constituent of bones and teeth and is used as a deoxidizer in steel. Symbol: Ca; atomic no: 20; atomic wt: 40.078; valency: 2; relative density: 1.55; melting pt: 842±2°C; boiling pt: 1494°C
[C19: from New Latin, from Latin calx lime]

cal·ci·um

(kăl′sē-əm)
Symbol Ca A silvery-white, moderately hard metallic element that is an alkaline-earth metal and occurs in minerals such as limestone and gypsum. It is a basic component of leaves, bones, teeth, and shells, and is essential for the normal growth and development of most animals and plants. Calcium is used to make plaster, cement, and alloys. Atomic number 20. See Periodic Table.

Prevalence of periodontitis in adults globally is 5-20% with higher prevalence seen in Pakistan.2,3 Recent studies have shown strong association of periodontitis with systemic diseases such as cardiovascular disease, diabetes mellitus Type-2 and osteoporosis.4 1,25 dihydroxy vitamin D (1,25(OH)2D), apart from regulating calcium homeostasis, plays an important role in immune modulation, boosting the immune system by upregulating the production of antimicrobial peptides.
Several concerns exist regarding vitamin D deficiency, including disorders of calcium homeostasis, cardiovascular diseases, autoimmune disorders, and some common cancers.
Vitamin D exerts neuroprotective effects on nervous tissues by modulating production of neurotrophin, synthesis of neuromediators, intracellular calcium homeostasis, and deterrence of oxidative stress9.
In the present study, we aim to clarify that whether ATX has a neuroprotective effect by means of regulating calcium homeostasis via L type channels and calcium binding proteins and NMDA subunits in primary cortical neurons.
However, the other causes of hypercalcemia described in the literature are Vitamin D intoxication, sarcoidosis, tuberculosis, some fungal infections, and thyrotoxicosis, The list goes on increasing as more and more insights in calcium homeostasis get unraveled.
Disturbance in the calcium homeostasis is associated with cardiac dysfunction and cardiac arrhythmias seen in dengue as suggested by in vitro studies.
Two distinct mechanisms relating calcium homeostasis to cancer pathways have been described.
[26] It readily crosses the blood brain barrier and inhibits entry of calcium into the neurons, primarily under pathophysiological conditions, such as ischemia or seizure activity, without any effect on normal calcium homeostasis. [27] The cerebrovascular effect of flunarizine could provide a direct neuroprotective effect against the damaging influx of calcium and could also prevent neuronal damage as a result of MES induced seizures.
The dysregulation of calcium homeostasis and calcium signaling is known to contribute to the neurotoxic side effects of CDDP Particularly, voltage-gated calcium channels are believed to play a role in CDDP-induced neurotoxicity [4].
In patients with Psoriasis and depression, higher plasmatic levels of pro-inflammatory cytokines, modified calcium homeostasis, (3-adrenergic receptor malfunction and increased melatonin secretion, are found (18, 19, 20,21).
