Satellite Evidence for Glyoxal Depletion in Elevated Fire Plumes [PDF]

open access: yesGeophysical Research Letters, 2023
Space‐borne observations are used to characterize the fate of formaldehyde and glyoxal in wildfire plumes. Their distribution measured by the Tropospheric Monitoring Instrument reveals striking differences between the two compounds near intense fires. In

Seasonal in situ observations of glyoxal and methylglyoxal over the temperate oceans of the Southern Hemisphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
The dicarbonyls glyoxal and methylglyoxal have been measured with 2,4-dinitrophenylhydrazine (2,4-DNPH) cartridges and high-performance liquid chromatography (HPLC), optimised for dicarbonyl detection, in clean marine air over the temperate Southern ...

Glyoxal retrieval from the Ozone Monitoring Instrument [PDF]

open access: yesAtmospheric Measurement Techniques, 2014
We present an algorithm for the retrieval of glyoxal from backscattered solar radiation, and apply it to spectra measured by the Ozone Monitoring Instrument (OMI).

Instrument intercomparison of glyoxal, methyl glyoxal and NO2 under simulated atmospheric conditions

open access: yes, 2015
The α-dicarbonyl compounds glyoxal (CHOCHO) and methyl glyoxal (CH[Subscript: 3]C(O)CHO) are produced in the atmosphere by the oxidation of hydrocarbons and emitted directly from pyrogenic sources.

Glyoxal vertical columns from GOME-2 backscattered light measurements and comparisons with a global model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
Glyoxal vertical column densities have been retrieved from nadir backscattered radiances measured from 2007 to 2009 by the spaceborne GOME-2/METOP-A sensor.

Oxyanion and tetrahedral intermediate stabilization by subtilisin : detection of a new tetrahedral adduct [PDF]

open access: yes, 2009
The peptide-derived glyoxal inhibitor Z-Ala-Ala-Phe-glyoxal has been shown to be ~10 fold more effective as an inhibitor of subtilisin than Z-Ala-Pro-Phe-glyoxal. Signals at 107.2 p.p.m. and 200.5 p.p.m.

Glyoxal damages human aortic endothelial cells by perturbing the glutathione, mitochondrial membrane potential, and mitogen-activated protein kinase pathways

open access: yesBMC Cardiovascular Disorders, 2021
Background Exposure to glyoxal, the smallest dialdehyde, is associated with several diseases; humans are routinely exposed to glyoxal because of its ubiquitous presence in foods and the environment.

Revisiting the global budget of atmospheric glyoxal: updates on terrestrial and marine precursor emissions, chemistry, and impacts on atmospheric oxidation capacity [PDF]

open access: yesAtmospheric Chemistry and Physics
Atmospheric glyoxal (CHOCHO) plays critical yet incompletely understood roles in tropospheric chemistry. Current models substantially underestimate glyoxal abundance over both land and ocean, indicating knowledge gaps in our understanding of its sources ...

Data_Sheet_1_Nanogold sol plasmon discattering assay for trace carbendazim in tea coupled aptamer with Au3+-glyoxal-carbon dot nanocatalytic reaction.docx

open access: yes, 2023
Carbendazim (CBZ) is a broad-spectrum fungicide, which is toxic to mammals. Therefore, it is very necessary to establish a sensitive detection for food safety. An experiment found that CDFe exhibited excellent catalysis for the nano-indicator reaction of
