Adele did not open the Belfast show in the traditional way as the singer walked through the audience while singing Hello before arriving on the main stage. In celebration of the leap year, Adele made one extremely sweet gesture for two audience members, helping one to propose to the other.
The parathyroid hormone (PTH) is secreted by the parathyroid gland, four small glands located on the posterior surface of the thyroid gland. The hormone is regulated by the calcium and phosphate levels in the blood and acts primarily on the bone and kidneys to increase circulating levels of calcium.
Parathyroid hormone regulates serum calcium through its effects on bone, kidney, and the intestine: In bone, PTH enhances the release of calcium from the large reservoir contained in the bones. Bone resorption is the normal destruction of bone by osteoclasts, which are indirectly stimulated by PTH.
