P110: Nitrous Oxide and Neuroinflammation
Nitrous oxide was an anaesthetic gas that was used for many years. There were many anaesthetic drugs in operations with many side effects. Nitrous oxide had some side effects too. But it was a safe gas in many times. In hospital personnel who worked in operating rooms exposure to this gas was important. The objective of this study was the introduction of nitrous oxide and neurologic side ...
متن کاملSynthetic chemistry with nitrous oxide.
This review article summarizes efforts to use nitrous oxide (N2O, 'laughing gas') as a reagent in synthetic chemistry. The focus will be on reactions which are carried out in homogeneous solution under (relatively) mild conditions. First, the utilization of N2O as an oxidant is discussed. Due to the low intrinsic reactivity of N2O, selective oxidation reactions of highly reactive compounds are ...
متن کاملElectron collisions with nitrous oxide
We have carried out theoretical studies of low-energy elastic electron collisions with nitrous oxide (N2O), obtaining differential, integral, and momentum-transfer cross sections. Polarization effects are incorporated in the electron-molecule scattering dynamics. A simple, objective, and physically motivated criterion is introduced for constructing a compact set of configurations that accuratel...
متن کاملSynthesis of azoimidazolium dyes with nitrous oxide.
A new method for the synthesis of industrially important azoimidazolium dyes is presented. The procedure is based on a reagent which is rarely used in the context of synthetic organic chemistry: nitrous oxide ("laughing gas"). N2O is first coupled to N-heterocyclic carbenes. Subsequent reaction with aromatic compounds through an AlCl3-induced C-H activation process provides azoimidazolium dyes ...
متن کاملThe Nitrous Oxide Test
The diagnosis of a left-to-right shunt generally depends upon the demonstration of significant differences in oxygen content among the venae cavae, the chambers of the right heart, and the pulmonary artery. The inconclusive or misleading results sometimes obtained with this method have stimulated interest in improved technics. The wide arteriovenous difference that normally exists during the in...
