Calcium imaging a single wavelength or two wavelengths expressed as a ratio (ratiometric indicators). The derived fluorescence intensities and ratios are plotted against calibrated values for known Ca levels to learn Ca concentration. Light field microscopy methods extend functional readout of neural activity capabilities in 3D volumes. 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
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
