Calcium imaging Calcium imaging Calcium imaging is a scientific technique usually carried out in research which is designed to show the calcium (Ca) status of an isolated cell, tissue or medium. Calcium imaging techniques take advantage of so-called calcium indicators, fluorescent molecules that can respond to the binding of Ca ions by changing their fluorescence properties. Two main classes of calcium indicators exist: chemical indicators and genetically encoded calcium indicators (GECI). Calcium imaging can be used to optically probe intracellular calcium in living animals. This technique has allowed studies of calcium signalling in a wide variety of cell types and neuronal activity
Calcium/cholecalciferol Calcium/cholecalciferol Calcium/cholecalciferol is a combination of a calcium salt (usually calcium carbonate) and vitamin D (cholecalciferol), available under many brand names and in many forms such as chewable tablets, coated tablets, and effervescent tablets. It is used to prevent and treat lack of calcium and vitamin D in the elderly, as well as adjunctive therapy for osteoporosis. Possible side effects include gastrointestinal problems, for example nausea and constipation. If very high doses are taken, signs of hypercalcaemia (too high blood calcium levels) have been described, such as stomach pain, vomiting, thirst, and tiredness. Extreme or long-term or overdose can theoretically
