Numerous studies have demonstrated that exposure to triazine herbicides affects the antioxidant defense system in fish, causing an imbalance between reactive oxidative system production and elimination and resulting in oxidative stress and organism damage [ 9, 29, 30].
The DNA molecules in all organisms are being damaged at a relatively high rate by endogenous processes, which include temperature, reactive oxygen species and other agents.
Radiation hormesis theory (Feinendegen et al. 2013) is based on the following biological facts: The DNA molecules in all organisms are being damaged at a relatively high rate by endogenous processes, which include temperature, reactive oxygen species and other agents.
This could be because the organism wasn't eliminated, or because the organism damaged nerve tissue, which may or may not slowly recover, depending on what type it is.
This suggests that repair should occur in all unicellular organisms, while damage segregation should be limited to toxic damage that cannot be repaired at reasonable cost.
Because of their potentially damaging effects, several antioxidant mechanisms have evolved to protect cells and organisms from damage by excessive amounts of these highly reactive mediators.
These compounds contribute in large part to the "acid rain" that can kill sensitive aquatic organisms and damage marble monuments and stone buildings.
Algae and higher aquatic plants, possessing high and constant amounts of VLCFAs are the most prone organisms to damage.
We review biocide delivery systems (BDS), which are designed to deter or control harmful organisms that damage agricultural crops, forests and forest products.
The 155-kDa plasma glycoprotein factor H (FH), which consists of 20 complement control protein (CCP) modules, protects self-tissue but not foreign organisms from damage by the complement cascade.
