It's great. Lots of NO is released.

And they were the first people to describe this new chemical transmitter, nitric oxide.

But I also became interested in research, and in particular I became interested in this substance, nitric oxide.

What nitric oxide does is it dilates blood vessels, so it lowers your blood pressure.

So if you're on the equator, December or June, you've got masses of NO being released from the skin.

So what you can do is you can multiply those data by the NO that's released and you can calculate how much nitric oxide would be released from the skin into the circulation.

We suspect a lot of these come from diet, green leafy vegetables, beetroot, lettuce has a lot of these nitric oxides that we think go to the skin.

And the reason for this, it turned out, after two or three years' work, was that in the skin we have huge stores not of nitric oxide, because nitric oxide is a gas, and it's released (Poof!) and in a few seconds it's away, but it can be turned into these forms of nitric oxide nitrate, NO3 nitrite, NO2 nitrosothiols.

Edinburgh in summer, the area beneath the curve is pretty good, but Edinburgh in winter, the amount of NO that can be released is next to nothing, tiny amounts.

Preparation Cadmium nitrate is prepared by dissolving cadmium metal or its oxide, hydroxide, or carbonate, in nitric acid followed by crystallization CdO 2HNO3 Cd(NO3)2 H2O CdCO3 2 HNO3 Cd(NO3)2 CO2 H2O Cd 4 HNO3 2 NO2 2 H2O Cd(NO3)2 Reactions Thermal dissociation at elevated temperatures produces cadmium oxide and oxides of nitrogen.
