Nodal signalling and asymmetry of the nervous system
(2016)
The role of Nodal signalling in nervous system asymmetry is still poorly understood. Here, we review and discuss how asymmetric Nodal signalling controls the ontogeny of nervous system asymmetry using a comparative ...
Wnt signaling modulates pre-and postsynaptic maturation: therapeutic considerations
(2010)
Wnt signaling regulates a wealth of aspects of nervous system development and function in embryonic stages and in adulthood. The expression of Wnt ligands and components of the Wnt signaling machinery in early stages of ...
Fast convergence delayed signal cancellation method for sequence component separation
(2015)
Delayed signal cancellation is one of the methods used to separate the negative- and positive-sequence components in unbalanced 3 phi systems. In this letter, a DSC methodology with fast convergence time is proposed and ...
Reactive Oxygen Species And Calcium Signals In Skeletal Muscle: A Crosstalk Involved In Both Normal Signaling And Disease
(2016)
Reactive Oxygen Species (ROS) have been profusely studied as agents of potential damage to living cells and they have been related to a number of pathological processes. Increasing evidence points to a more positive role ...
Extended amplification of acoustic signals by amphibian burrows
(2016)
Animals relying on acoustic signals for communication must cope with the constraints imposed by the environment for sound propagation. A resource to improve signal broadcast is the use of structures that favor the emission ...
