Paul Bert’s OR on Wheels: A Hyperbaric Nitrous Oxide Chamber

Nitrous Oxide Chamber Methodology Guidelines

Automated, low-power chamber system for measuring nitrous oxide emissions.

Continuous measurement of soil NO emissions is needed to constrain NO budget and emission factors. Here, we describe the performance of a low-power Teledyne NO analyzer and automated chamber system, powered by wind and solar, that can continuously measure soil NO emissions. Laboratory testing of the analyzer revealed significant temperature sensitivity, causing zero drift of -10.6 nmol mol °C. ...

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 ...

Nitrous oxide emissions from managed grassland: a comparison of eddy covariance and static chamber measurements

Managed grasslands are known to be an important source of N2O with estimated global losses of 2.5 Tg N2ON yr−1. Chambers are to date the most widely used method to measure N2O fluxes, but also micrometeorological methods are successfully applied. In this paper we present a comparison of N2O fluxes measured by non-steady state chambers and eddy covariance (EC) (using an ultra-sonic anemometer co...

Growth suppression of four cancer cells by hyperbaric nitrous oxide and methotrexate

BACKGROUND Nitrous oxide concentration is easily controlled by respiratory ventilation. It suppresses bone marrow via the inhibition of thymidylate synthesis. The aim of this work was to determine the optimal pressure and exposure duration of nitrous oxide, as well as methotrexate concentration that maximizes the suppression of 4 cancer cells: CCRF-CEM, K562, A549 and MDA-MB-231. METHODS Each...
