Nerve freezing may help fight obesity

25.03.2018

Freezing the vagus nerve helps reduce appetite and helps in the fight against excess weight with moderate and moderate obesity, a group of American scientists found.

Researchers from the Emory University School of Medicine, the State University of New York at Buffalo, and the Pennsylvania State University Medical Center conducted a study of ten patients with grade XNUMX and XNUMX obesity.

Each of them underwent a procedure to freeze the posterior trunk of the vagus nerve, through which hunger signals enter the brain. A needle was inserted into the back of the patients and a certain part of the nerve was frozen using cryogenic argon. After that, for 90 days, scientists observed the condition of people.

According to the results of the study, all participants in the experiment noted a decrease in appetite. Patients' weight decreased by 3,6% and overweight body mass index (BMI) fell by 14%. No complications or side effects were observed after freezing of the vagus nerve. The researchers note that the procedure is safe and produces real results.

"The medical literature shows that the vast majority of weight loss programs fail, especially when people try to reduce food intake. When our stomachs are empty, the body senses this and switches to survival mode in search of food," says lead author David Prologo.

According to the scientist, this study is aimed at reducing the strength of the signal that an empty stomach transmits to the brain.

"We developed this treatment for obese patients of the first and second degree in order to reduce the wasting effect of weight loss," explains Prologo.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Earth's magnetic field has a clear cycle 21.08.2021

Scientists from the University of Liverpool studied the history of the Earth's magnetic field and came to the conclusion that its strength periodically decreases and then increases again. The cycles are 200 million years long.

Experts conducted a paleomagnetic analysis of rocks from ancient lava flows in East Scotland. The age of the samples ranged from 200 to 500 million years.

The results showed that 332-416 million years ago, the strength of the geomagnetic field was less than 25% of what it is today. A similar decline also occurred 120 million years ago. The researchers called this period the Middle Paleozoic dipole minimum. Scientists have concluded that the strength of the Earth's magnetic field is cyclical and weakens every 200 million years.

The scientists noted that after the weakening they identified, the magnetic field came to stability and kept it for 50 million years. This phenomenon is called the Keeman superchron.

The Earth's magnetic field protects the planet from solar radiation. Scientists have long established that it is unstable. The north and south poles are constantly shifting and can even completely switch places. Knowing the field's past changes can indicate how it will behave in the future.

The weakening of the field has a direct impact on life on the planet. Recently, experts have determined that the Devonian-Carboniferous mass extinction is associated with increased levels of UVB rays; at the same time, the power of the magnetic field decreased noticeably.
