ALKYLGUANIDINE NITRATES AND ALKYLNITROGUANIDINES

The nitrates and myocardial ischemia.

Alkylguanidine inhibition of ion absorption in oat roots.

The effect of various alkylguanidines on ion absorption and energy metabolism in oat (Avena sativa cv. Goodfield) roots has been investigated. Of several alkylguanidines tested, octylguanidine was the most effective inhibitor of both K(+) and Cl(-) absorption by excised roots. At 225 mum octylguanidine, the transport of both ions was inhibited within 60 seconds and to a similar extent. Octylgua...

NITRATES AND EICOSANOIDS Nitrates and endothelial prostacyclin production: studies in vitro

The hypothesis that nitrates evoke prostacyclin production by vascular endothelium has been reevaluated on cultured umbilical vein endothelial cells and in vascular fragments, both obtained from humans. Endothelial cell monolayers (passages 1 and 2) were washed free of culture medium and exposed for 3 to 5 min to buffer or nitroglycerin (NTG), isosorbide dinitrate (ISDN), or isosorbide-5mononit...

Marine Light Alkyl Nitrates

In the usual photoionization process, the absorption and emission of photons between the light field and the photoexcited electron packet is an arbitrary process that broadens the energy distribution of the electrons. However, there is no net exchange of energy between the two, and the drift velocity of the electron packet is unchanged. Kienberger et al. (p. 1144; see the Perspective by Lewenst...
