Oxidative Shielding or Oxidative Stress? [PDF]

open access: yesThe Journal of Pharmacology and Experimental Therapeutics, 2012
In this review I report evidence that the mainstream field of oxidative damage biology has been running fast in the wrong direction for more than 50 years. Reactive oxygen species (ROS) and chronic oxidative changes in membrane lipids and proteins found in many chronic diseases are not the result of accidental damage.

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

open access: yes
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...
