Nimesulide limits kainate-induced oxidative damage in the rat hippocampus [PDF]

open access: yesEuropean Journal of Pharmacology 390(3): 295-298 (2000), 2007
Kainate induces a marked expression of cyclooxygenase-2 after its systemic administration. Because cyclooxygenase-2 activity is associated to the production of reactive oxygen species, we investigated the effects of nimesulide, a selective cyclooxygenase-2 inhibitor, on kainate-induced in vivo oxidative damage in the rat hippocampus.

Superoxide reductase from Desulfoarculus baarsii: reaction mechanism and role of glutamate 47 and lysine 48 in catalysis [PDF]

open access: yesBiochemistry, American Chemical Society, 2001, pp.5032-40, 2015
Superoxide reductase (SOR) is a small metalloenzyme that catalyzes reduction of O(2)(*)(-) to H(2)O(2) and thus provides an antioxidant mechanism against superoxide radicals. Its active site contains an unusual mononuclear ferrous center, which is very efficient during electron transfer to O(2)(*)(-) [Lombard, M., Fontecave, M., Touati, D., and Nivi ...

Pharmacological effects of gastrodin: Insight into neurological diseases and mechanism in ferroptosis and pyroptosis

open access: yesIbrain, Volume 11, Issue 1, Page 74-83, Spring 2025.
Pharmacological effects of gastrodin include prevention and treatment of cognitive decline and reperfusion injuries, anticonvulsion, antiepilepsy, antidepressants, and analgesia, which are related to antiferroptosis and antipyroptosis. Abstract Gastrodin, as an effective monomer of gastrodia elata, plays a significant role in anti‐inflammatory ...

Coordinated transcriptional regulation between a reactive oxygen species-responsive gene network and the circadian clock in Arabidopsis thaliana : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Plant Biology at Massey University, Plant Biology, New Zealand [PDF]

open access: yes, 2012
Most organisms have evolved endogenous biological clocks as internal timekeepers to fine-tune physiological processes to the external environment. Energetic cycles such as photosynthesis and glycolytic cycles are physiological processes that have ...

Leveraging core enzyme structures for microbiota targeted functional regulation: Urease as an example

open access: yesiMeta, EarlyView.
We present an innovative methodology that integrates core enzyme identification, protein structural characterization, regulator virtual screening, and functional validation to achieve precise microbiome functional regulation. As a proof of concept, we focused on the regulation of urea decomposition by the rumen microbiota in ruminants. This methodology
