Nitrates are widely used in anginal prophylaxis. In spite of the fact that the concept of nitrate tolerance was first put forward many years ago, the question of tolerance has remained controversial. There is widespread agreement that tolerance does occur to the effects of nitrates on arterial pressure.

Nitrate signalling: Functions of a nitrate transceptor
Nature Plants, 2015The nitrate transporter NRT1.1 is a versatile plasma-membrane protein that mediates not only nitrate uptake in roots, but also nitrate sensing and signalling. A study of the structural features of NRT1.1 reveals how this protein can coordinate a range of physiological and morphological responses to nitrate.

The surface tension of molten TlNO/sub 3/ has been measured over the temperature range 220-350 /sup 0/C, using the maximum bubble pressure method. We have also measured the surface tension of the binary mixtures TlNO/sub 3/-LiNO/sub 3/ and TlNO/sub 3/-KNO/sub 3/ at 350 /sup 0/C over the entire composition range. 3 tables, 2 figures.

Ipso Nitration. Regiospecific Nitration via Ipso Nitration Products.
1985Abstract : Work has been focused on developing efficient methods of preparing 4-alkyl-nitrocyclohexadienones and 4-alkyl-4-nitrocyclohexadienols by batch and flow processes. Detailed studies of the thermal and acid-catalyzed rearrangements of 4-alkyl-4-nitrocyclohexadienones have been made, leading to mechanistic assignments that may have broader ...
