Estimating global nitrous oxide emissions by lichens and bryophytes with a process-based productivity model [PDF]

Biogeosciences, 2017
Nitrous oxide is a strong greenhouse gas and atmospheric ozone-depleting agent which is largely emitted by soils. Recently, lichens and bryophytes have also been shown to release significant amounts of nitrous oxide.

Psychedelic concentrations of nitrous oxide reduce functional differentiation in frontoparietal and somatomotor cortical networks

Communications Biology, 2023
Despite the longstanding use of nitrous oxide and descriptions of its psychological effects more than a century ago, there is a paucity of neurobiological investigation of associated psychedelic experiences.

A retrospective cohort study on red blood cell morphology changes in pre-school age children under nitrous oxide anesthesia

BMC Anesthesiology, 2021
Background Megaloblastic anemia or bone marrow changes could occur after prolonged nitrous oxide inhalation via vitamin B12 inactivation related DNA synthesis impairment. Previous researches have studied hematological changes with nitrous oxide exposure,

Sevoflurane concentration for cannulation in developmental disabilities

BMC Anesthesiology, 2022
Objective The goal of this study was to compare the end-tidal sevoflurane concentration and time for intravenous cannulation at induction of anesthesia using sevoflurane with or without nitrous oxide in healthy children and in those with developmental ...

Associations of socio-demographic characteristics, well-being, school absenteeism, and substance use with recreational nitrous oxide use among adolescents: A cross-sectional study.

PLoS ONE, 2021
PurposeA rapid increase of recreational nitrous oxide use (i.e. laughing gas, N2O) has been reported in several countries, while it has received limited attention in scientific research.

High nitrous oxide emissions from temporary flooded depressions within croplands

Communications Earth & Environment, 2023
Nitrous oxide is an important greenhouse gas and emissions from managed ecosystems are directly correlated to anthropogenic nitrogen input. Here we have measured nitrous oxide emissions from flooded depressions within croplands and from incubated soil ...

An intercomparison of oceanic methane and nitrous oxide measurements [PDF]

Biogeosciences, 2018
Large-scale climatic forcing is impacting oceanic biogeochemical cycles and is expected to influence the water-column distribution of trace gases, including methane and nitrous oxide.

Nitrous oxide inhalation-induced cerebral venous sinus thrombosis in a 20-year-old man: A case report

Heliyon, 2023
Nitrous oxide is increasingly abused in the young population and has been verified to induce neuropathy, myelopathy, encephalopathy, and thrombosis. Nitrous oxide-related thrombosis was identified in the coronary artery, ascending aorta, pulmonary artery,

Nitrous oxide emissions from soils: how well do we understand the processes and their controls?

Philosophical Transactions of the Royal Society B: Biological Sciences, 2013
Although it is well established that soils are the dominating source for atmospheric nitrous oxide (N2O), we are still struggling to fully understand the complexity of the underlying microbial production and consumption processes and the links to biotic (

The consequences of niche and physiological differentiation of archaeal and bacterial ammonia oxidisers for nitrous oxide emissions

The ISME Journal, 2018
High and low rates of ammonium supply are believed to favour ammonia-oxidising bacteria (AOB) and archaea (AOA), respectively. Although their contrasting affinities for ammonium are suggested to account for these differences, the influence of ammonia ...
