Like the M 1 and M 3 muscarinic receptor, M 5 receptors are coupled with G proteins of class Gq that upregulate phospholipase C and, therefore, inositol trisphosphate and intracellular calcium as a signaling pathway.
Radioactive iodine is a very effective type of treatment for cancer of the thyroid gland. Thyroid cells absorb iodine. The radioactive iodine from the drink or capsule is absorbed into your body and picked up by the thyroid cancer cells wherever they are. So it can kill the cancer cells even if they have spread.
1. Radiation Exposure. Potassium iodine has been used to help individuals exposed to radiation by reducing the harmful accumulation of radioactive substances in the thyroid. However, It has been said that nascent Iodine may be 4-7 times more effective than potassium iodide and is much safer to use.. Radiation Exposure.
