Novel direct approach for placement of permanent transvenous pacing leads after Fontan procedure

Annals of Pediatric Cardiology, 2018
The need for transvenous pacing (patients who have exhausted epicardial options) after a Fontan-type operation has been recognized. Many novel strategies have been proposed, but currently, all of them require additional maneuvers or rerouting of the ...

A 2-dimensional Geometry for Biological Time [PDF]

, 2011
This paper proposes an abstract mathematical frame for describing some features of biological time. The key point is that usual physical (linear) representation of time is insufficient, in our view, for the understanding key phenomena of life, such as ...

Mild Focal Cooling Decouples Dendrites to Reconfigure Cortical Output

Advanced Science, EarlyView.
Mild cooling of the cortical surface selectively modulates apical dendritic excitability, plasticity, and somato‐dendritic coupling, while uncoupling these effects from basal dendrites, and reshapes apical‐driven responses in barrel cortex during whisker touch.
