Exposure to low UVA doses increases KatA and KatB catalase activities, and confers cross-protection against subsequent oxidative injuries in pseudomonas aeruginosa
(Society for General Microbiology, 2016-05)
Solar UVA radiation is one of the main environmental stress factors for Pseudomonas aeruginosa. Exposure to high UVA doses produces lethal effects by the action of the reactive oxygen species (ROS) it generates. P. aeruginosa ...
Eucalyptus ESTs corresponding to the protoporphyrinogen IX oxidase enzyme related to the synthesis of heme, chlorophyll, and to the action of herbicides
(2005-12-01)
This work was aimed at locating Eucalyptus ESTs corresponding to the PROTOX or PPO enzyme (Protoporphyrinogen IX oxidase, E.C. 1.3.3.4) directly related to resistance to herbicides that promote oxidative stress, changing ...
Ethanol as a Prodrug: Brain Metabolism of Ethanol Mediates its Reinforcing Effects
(2011)
Background: While the molecular entity responsible for the rewarding effects of virtually all drugs of abuse is known, that for ethanol remains uncertain. Some lines of evidence suggest that the rewarding effects of alcohol ...

Biochemical and physiological changes of Tabebuia roseoalba (Ridl.) Sandwith (Bignoniaceae) seeds under storage
(ABRATES - Associação Brasileira de Tecnologia de Sementes, 2014)
Tabebuia roseoalba (Ridl.) Sandwith is a Brazilian forest species, with great use in landscaping and reforestation, occurring mainly in the semi-deciduous forest. Seeds are small, lightweight, winged and wind-dispersed. ...

Tabebuia roseoalba (Ridl.) Sandwith is a Brazilian forest species, with great use in landscaping and reforestation, occurring mainly in the semi-deciduous forest. Seeds are small, lightweight, winged and wind-dispersed. ...
Sunflower cotyledons cope with copper stress by inducing catalase subunits less sensitive to oxidation
(Elsevier Gmbh, 2011-07)
Copper is an essential trace element for living organisms, in excess, can be toxic to the cell because of its capacity to generate reactive oxygen species (ROS). Catalase (CAT) catalyzes the dismutation of hydrogen peroxide ...
Participation of catalase in voluntary Ethanol consumption in perinatally low-level lead-exposed rats
(Wiley, 2013-06)
Background: Environmental lead (Pb) exposure and alcohol abuse pose significant public health problems for our society. One of the proposed mechanisms of action of the developmental neurotoxicant Pb is related to its ability ...
