Calcium nitrate salt" 5Ca(NO).NHNO·10HO. This is called calcium ammonium nitrate. Formulations lacking ammonia are also known: Ca(NO)·4HO (11.9-0-0 + 16.9 Ca) and the water-free 17-0-0 + 23.6 Ca. A liquid formulation (9-0-0 + 11 Ca) is also offered. An anhydrous, air-stable derivative is the urea complex Ca(NO)·4[OC(NH)], which has been sold as Cal-Urea. Calcium nitrate is also used to control certain plant diseases. For example, dilute calcium nitrate (and calcium chloride) sprays are used to control bitter pit and cork spot in apple trees. Calcium nitrate is used in waste water pre-conditioning for odour emission prevention. The waste water pre-conditioning is based
N-type calcium channel having a role in the transmission of nociceptive information in the body. A new drug, Ziconotide, is being tested to alter N-type channels in order to treat these conditions of chronic pain. One of the newest medicines is an analgesic drug that works through targeting N-type calcium channels specifically in order to lessen the transmission of pain. Peptide ɷɷ-conotoxins are what bind to the N-type calcium channels in order to block ion permeation, which then blocks the influx of calcium and the transmission of the nociceptive responses. Neurons located in the posterior horn of the spinal cord experience ɷɷ-conotoxins that,
