While excessive ROS levels are toxic, sub-lethal production serves an important signaling function, particularly in cancers, were ROS promote cell proliferation, migration and invasion.
After the roots are harvested, particular strains of cassava can produce possibly toxic levels of cyanogens that can create lethal cyanide production.
When malaria parasite (Plasmodia) consumes iron-rich haemoglobin within its acidic food vacuole in erythrocytes, the exposure of artemisinin to haem-derived iron results in lethal ROS production that exerts fatal toxicity to the parasite.
This eventually resulted in the production of lethal amounts of reactive oxygen molecules.
"Compared to an American production like 'Lethal Weapon 4,' it is very small potatoes".
Growing up the toxic walls of the abandoned nuclear power plant at Chernobyl, fungi learned to fight its lethal radioactivity by the production of melanin.
Another tailored weapon is the enhanced radiation warhead, or neutron bomb, a low-yield (on the order of one kiloton), two-stage thermonuclear device designed to intensify the production of lethal fast neutrons in order to maximize mortality rates while producing less damage to buildings.
Inhibition of bacterial growth could have been caused by several factors, including cell membrane damage, oxidative stress and cell elongation, resulting in the production of lethal cells.
The destructive effect of Bacillus species on M. incognita might be due to the production of lethal nematicidal antibiotic compounds and enzymes which directly affected the nematode reproduction and juvenile mortality (Gao et al., 2016).
Bacillus anthracis, the agent responsible for inhalation anthrax, exerts its lethal effects via the production of anthrax toxin (protective antigen, lethal factor and oedema factor); anthrax kills because the toxin overwhelms the patient before innate host defence systems have a chance to eradicate the invaders.
Alternatively, the use of chick embryos to generate vaccines against H5 viruses could be challenging because influenza viruses grown for vaccine production are lethal to the embryos [32].
