Russian scientists will conduct an experiment on the treatment of arrhythmia

Russian scientists are preparing to conduct a unique experiment on an isolated cardiopulmonary complex to test the work of biological pacemaker cells. This was announced on December 2 by Maxim Zhulkov, a cardiovascular surgeon and researcher at the E. N. Meshalkin National Research Center (NMIC).

We are talking about pacemaker cells, special cells of the heart that set the frequency of its contractions and transmit control signals. If their work is disrupted, patients are usually implanted with an artificial pacemaker. Russian experts are exploring the possibility of replacing the electrostimulator with natural cells grown from the patient's own stem cells. In 2024, Novosibirsk has already performed the world's first operation with the introduction of such cells.

"One of the models is to conduct tests on an autoperfused, that is, isolated cardiopulmonary complex. In order to verify the effectiveness of these pacemaker cells, it is necessary to isolate them from the influence of the central nervous system and the humoral system. Our method, which was developed with the aim of preserving the heart and preserving its functions, is ideally suited to study pacemaker cells specifically," Zhulkov said in an interview with TASS.

Increased difficulty level: how high-tech medical care works in Moscow

What is hidden behind this term, how has the capital's healthcare system changed and what role do new hospitals play in this?

Previously, the NMIC team named after Meshalkina proposed the technology of autoperfusion, which preserves a functioning donor heart during transportation. In the traditional scheme, the heart is stopped and cooled, and the safe transportation time does not exceed four hours. The new technology makes it possible to keep the organ active longer and makes it possible to conduct experiments with pacemaker cells in stable conditions.

As it was canceled in the article, pacemaker research, supported by a grant from the Russian Science Foundation, will continue until the end of 2028. According to Alexander Romanov, the head of the scientific group, the world's leading laboratories are currently working on various ways to introduce biological pacemakers into the heart. One of the promising options is to create a carrier gel through which cells can be injected minimally, using a conventional injection.

An increase in the detection of an increased amount of glucose indicates the prevalence of carbohydrate metabolism disorders, experts say.

Endocrinologist and nutritionist Armine Afonina warned on August 18 that wheat bread and rice can increase blood sugar. Among such products, the doctor also identified mashed potatoes, small pasta, canned beans and corn, instant porridge, semolina, couscous, sweet muffins, cornflakes, popcorn, waffles, chips.
