At upper levels of the hierarchy of the reproductive axis, a complex network of neuroendocrine systems act coordinately to regulate the reproductive functions.
Increased levels of ROS generated in working muscles favor a change in the redox-balance towards a more pro-oxidant state counteracted by a complex network of antioxidant systems [ 44], as suggested by the association of exercise with the "Oxidative stress induced gene expression via Nrf2" pathway.
In the human body, a complex network of antioxidant defence systems (mainly endogenous enzymatic antioxidant systems) is supported by, and interacts with, small antioxidant molecules derived from the diet to protect the tissues from oxidative stress.
These collective phenomena include social aggregation phenomena as well as emergence of consensus, swarming, and synchronization in complex network of interacting dynamic systems such as mobile robots and sensors.
The brain, of course, consists of a complex network of highly interactive systems.
Systems biological tools offer an informative insight into the complex network of the immune system in our body.
Since some reports showed that a gene dosage change of clock related genes influenced the clock regulatory network and downstream signals [ 33, 34], plants may have flexibly modulated the complex network of the clock system after polyploidy events and subsequent gene deletion events.
Municipal engineers manage a complex network of technical and natural systems to treat and remove these temporary water flows from cities as quickly as possible.
Industrial processes handling combustible dusts usually comprise numerous pieces of equipment, such as grinders, mixers, dryers, classifiers, dust collectors, and storage hoppers, interconnected by a more or less complex network of pipes and conveying systems.
Government is viewed as one intertwined system, a complex network of temporary relationships fashioned to work out problems as they arise and linked by informal channels of communication.
