snake cardiological

David L Chandler
The smooth, powerful muscles of a newborn baby?s heart are pulsing normally, squeezing in and letting go rhythmically as a 3-mm-wide catheter-like tube snakes its way through, entering via an artery and being guided slowly by a surgeon. When it reaches its target?a protruding knot of malformed muscle tissue within a ventricle that has been partly blocking the valve?the tip of the precisely controlled tube whirs into action, with tiny scissor-like rotating blades gently grinding up the excess tissue as those pieces are sucked back into the device, leaving no floating particles that could lead to a blockage elsewhere...

Cardiac leaders need to put forth cogent, well-articulated, conceptually sound reasons for pursuing issues that they consider to be significant to the future of their service. Logic, rationality, and quantification of issues are "givens"--they are the price of admission that one pays to have an issue contested in the organizational arena. Understanding the larger sphere in which CV issues reside by contextualizing logic and rationality in terms of organizational culture, power, politics, group dynamics, and ego improves the chance that the cardiac agenda will receive thoughtful consideration and support by organizational decision-makers...

A comparative analysis of cardiotropic activity of toxins has been studied in experiments on isolated heart of the poisonous animals from different systematic groups living on the territory of the USSR: reptiles (the venom of cobra, Vipera lebetina, Ancistrodon blomhoffi), amphibian (the venom of Bufo, Bombina, salamander), arachnids (the venom of Apis, Scolopendra, scorpion). The specific cardiotropic activity of the scorpion and Bufo venom has been discovered. The mechanisms of the cardiostimulative activity of scorpion venom have been found to be due to the activation of cellular adrenoreactive structures, and the Bufo venom to the activation of the intracellular calcium...
