The way to measure pressure in a cage is found


Maintenance of pressure at one level is the most important indicator of a homeostasis (that is constancy of the internal environment) and his violation influences all human body. By analogy with all over, the cage has the pressure too. And this indicator is extremely important for microscopic processes. And now we can learn this indicator, at last. And, very interesting way.

during a series of experiments the group of researchers of the University of Geneva has created the special rotating molecule. Writes the Nature Chemistry edition about it. It is known that the majority of bacteria, mushrooms and multicellular has an external cover. And each cage can change in a size and the volume of this change is rather big. At the same time tourist's mountain pressure in a cage increases and if not to control this process - the cage will burst. The special systems limiters which are "built in" a cellular membrane are for this purpose used.

by "Usual" methods to measure pressure in a cage is problematic and for these purposes scientists have created the rotating molecule FliptR. She thanks to the structure measures the level of a tension of a cellular membrane. Rotation of a molecule near a cellular wall registers change of the size and on the basis of the obtained data from a molecule, also knowing a form and volume of a cage, it is possible to calculate intracellular pressure.

Information on internal pressure in a cage will allow to study better intracellular metabolism and also will help, for example, with studying of influence of drugs and toxins on our organism.
