Dangers of Early Antibiotic Use

08.04.2017

Prescribing antibiotic drugs to children can be an extremely dangerous medical practice. A group of scientists from Belgium, Israel and Canada found that early use of antibiotics can lead to a range of serious consequences.

The use of antibiotics negatively affects the composition of the intestinal microflora, as well as the neurochemical activity of brain regions associated with the activity of the immune system. Also, the use of these drugs reduces social activity and anxiety, but increases aggressiveness.

"The early use of antibiotics deals a complex blow to the intestinal microflora - and this, as you know, is an extremely important biological mechanism for the body that controls the immune system. As a result, it suffers to a particularly pronounced degree also because antibiotics, getting into a fragile organism, affect the brain, in particular, those parts of it that regulate immunity," say the authors of the study, employees of Canada's McMaster University.

Scientists confirm their words with the results of experimental studies carried out on laboratory rodents.

Baby mice were injected with penicillin, and then the effects of its use were recorded. The conclusions obtained as a result are also valid for humans, experts say.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

The genetics of loneliness 17.10.2011

Stephen Cole from the University of Los Angeles (USA) compared which genes are active in the white blood cells of lonely and sociable people, wealthy relatives and friends.

As you know, these blood cells are in charge of immunity. It turned out that the genes that protect against microbes are more active in lonely people, and those that protect against viruses are more active in sociable people.

The author of the study believes that such differences are associated with lifestyle. We catch viruses mainly from people, communicating with them, and microbes are constantly present in the environment and in food. Viruses, as a rule, die quite quickly outside the body.
