    A method for treating high blood pressure by radio waves is called catheter denervation of the kidneys. The method offers patients for a long time suffering from an ailment who have not felt the effect of taking medication, changing their lifestyle and strict diets so that they can get rid of the fear of waiting for a heart attack or stroke. On groups of volunteers, it was found that the method lowers the pressure a little, but is stable.

    The procedure for supplying radio waves through the kidneys looks like this: a catheter is inserted into the large blood vessel of the inguinal region and advances into the kidneys, high-energy radio waves that cut off the renal nerves, the tension of which provides an increase in blood pressure, is fed through it.

    The average pressure of 106 people in the experimental group was 178 by 97 mm.gt;Art. After 6 months, in the new method testers, the average pressure decreased by 32 to 12 mm.gt;Art.

    The spray from burns from stem cells of the patient was developed by medical engineers of the University of Utah( USA).Even the first tests showed significant results.

    They were performed on a patient who had a history of diabetes for a long time and had an open wound of the lower limb. The wound was tried to heal with traditional medicines and skin transplants for more than a month, but it did not even begin to drag out.

    Using the new technology, scientists have achieved wound healing within a week. And the stem cells were useful to the patient during heart bypass surgery, which was no less successful.

    To the effective and rapid treatment of burns for centuries, surgeons of field medicine aspire. Medical engineers suggest that it is quite possible to grow skin in bioreactors in five years.

    Electronic sensor skin was developed by medical engineers at the University of Berkeley. Sensory skin from flexible sensors is characterized by developers as a reliable material with minimal energy consumption. Electronic leather has some properties of the human, for example, perceives objects to the touch.

    According to the idea, the invention will be useful to people with amputated limbs and will be used in the design of medical robots.

    The basis of high-sensitivity electronic skin is made up of inorganic single-crystal semiconductors. A group of test engineers raised them from silicon and germanium, then the obtained nanowire was fixed on the cylinder, folded on a polyamide substrate.

    This flexible and thin electronic material was installed in a matrix of transistors consisting of hundreds of semiconductor nanowires. The design of the rubber was sensitive to pressure up to 15 kPa, equivalent to the force required to hold light objects.

    Robot, whose hands are covered with this skin, could lift and hold the glass glass without crushing it.

    The size of the matrix with an ordered nanowire circuit is 122 cm2, it consumes up to 5 volts of electricity and is exactly functional after 2 thousand flexion-extension.

    We hope that these discoveries will significantly improve the quality of life of patients!
