Pulmonary Hypertension Is a Probable NO/ONOO− Cycle Disease: A Review
Figure 1
1(a)–1(e) are essentially identical diagrams of the proposed NO/ONOO− cycle, where each arrow represents one or more mechanisms whereby one element of the cycle acts to increase the levels of a second element of the cycle. Each of these differs from the others in that arrows involved in cycles that constitute parts of the overall NO/ONOO− cycle are dashed, so that these constituent cycles can be considered independently of each other.
