Pulling on the heart strings: a new mechanism within Starling's law of the heart?
When heart muscle is stretched, it increases the force of contraction so that cardiac output matches venous return on a nearly beat-to-beat basis, and this was elegantly described by Ernest H. Starling (1866 to 1927), who formulated “Starling’s law of the heart” on the basis of earlier work (see historical review2). The physiological basis of this essential homeostatic mechanism has remained qu...
متن کاملBehind the scene, something else is pulling the strings: emphasizing parasitic manipulation in vector-borne diseases.
Merging the field of epidemiology with those of evolutionary and behavioural ecology can generate considerable fundamental knowledge, as well as help to guide public health policies. An attempt is made here to integrate these disciplines by focusing on parasitic manipulation in vector-borne diseases. Parasitic manipulation is a fascinating strategy of transmission which occurs when a parasite a...
متن کاملFrom decay to complete breaking: pulling the strings in SU(2) Yang-Mills theory.
We study {2Q+1} strings connecting two static charges Q in (2+1)D SU(2) Yang-Mills theory. While the fundamental {2} string between two charges Q=1/2 is unbreakable, the adjoint {3} string connecting two charges Q=1 can break. When a {4} string is stretched beyond a critical length, it decays into a {2} string by gluon pair creation. When a {5} string is stretched, it first decays into a {3} st...

extinguished by the transfer. But the extent of the transformation is not yet clear. “It’s possible that what we are doing is turning everything into an oocyte,” says Gurdon. But he believes that oct4 expression is a good sign that the cells are at least headed toward becoming stem cells. Stem cell characteristics may develop only through sequential inductive events. But the optimists are hopin...
متن کاملPulling knotted polymers
– We compare Monte Carlo simulations of knotted and unknotted polymers whose ends are connected to two parallel walls. The force f exerted on the polymer is measured as a function of the separation R between the walls. For unknotted polymers of several monomer numbers N , the product fN is a simple function of R/N , where ν 0.59. By contrast, knotted polymers exhibit strong finite-size effects ...
