Evaluation of effects of photooxidized Vespa orientalis venom on memory and learning in rats

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2011
Wasp venom is mixture of complex proteins that have several physical and pharmacological properties. The photochemical detoxification of Vespa orientalis venom is expected to generate photooxidized venom sac extract (PVSE).

Effects of mixing on evolution of hydrocarbon ratios in the troposphere [PDF]

open access: yes, 2007
Nonmethane hydrocarbon (NMHC) concentration ratios provide useful indicators of tropospheric oxidation and transport processes. However, the influences of both photochemical and mixing processes are inextricably linked in the evolution of these ratios ...

Comparison of terrestrial and Martian TEC at dawn and dusk during solstices

open access: yesEarth, Planets and Space, 2020
This paper used the similarities between the ionospheres on Mars and Earth, the most similar of the terrestrial planets, to examine the relative importance of photochemical and transport processes at dawn and dusk.

The atmospheric oxidizing capacity in China – Part 1: Roles of different photochemical processes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Atmospheric oxidation capacity (AOC) characterizes the ability of the atmosphere to scavenge air pollutants. However, the processes involved in China, where anthropogenic emissions have changed dramatically in the past decade, are not fully understood. A
