Is it true that our children are getting fat?

Yes. According to the latest research, more than 2 million children and adolescents over the past 10 years have gained from 15 to 20% of excess weight. The reason - the frequent use of sweets and "fast food" (Fast food).

How did medicine originate?

We need medicine to treat people from all sorts of diseases. You know that there are many ways to heal people. If you or your parents suddenly fall ill, you will call a doctor who will apply all his knowledge and experience to cure you with the help of science. But instead, you may use the remedy that your grandmother gave you, or try to cure a person with a spell, that is, apply the knowledge of traditional medicine.

Until medicine became a science, people used traditional medicine. Primitive people came up with a variety of, sometimes very strange causes of diseases, and therefore treated them based on magic and other means that seemed to be beneficial. They used heat and cold, bloodletting, massage, and medicinal herbs.

The medicine of Ancient Egypt, which was considered the most effective in antiquity, was based on spells. People used various ointments and drugs: honey, salt, cedar oil, brain, liver, heart and blood of various animals were often used as medicines. Sometimes these remedies helped, sometimes they didn't.

But scientific medicine originated only in Ancient Greece. More than 2000 years ago, a man named Hippocrates collected medical knowledge in one book, The Hippocratic Collections. It marked the beginning of scientific medicine, as it was based on the need to study the patient before making a diagnosis.

His book described the symptoms and course of diseases. For the first time, instead of relying on magic, treatment was carried out after examining the patient and studying the disease, as well as on the basis of the experience of predecessors. Modern medicine is based on the same principles.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Single Protein Deactivation Treats Heart Failure 25.04.2018

A group of researchers from the Children's Heart Institute in Cincinnati (USA) has learned how to block the protein fibronectin to treat cells damaged by a heart attack.

The team, led by Dr. Burns Blaxall, tested a custom-made pUR4 peptide that blocked the action of fibronectin in heart cells donated by heart failure patients.

The treatment prevented the loss of human heart cells and restored their function. In addition, fibrosis was reduced and cardiac function improved in mice after a simulated heart attack.

“Normal fibronectin is a positive active element in the body. It helps form a cellular matrix for the connective tissues of the body, contributing to tissue recovery after injury,” the researchers explain. “But this protein reacts too sharply to a heart attack: it polymerizes and creates too much connective matrix "This causes an overactive production of dysfunctional myofibroblasts that damage the heart."

The pUR4 compound attaches to the surface of fibronectin, preventing the formation of a matrix from this protein and effectively eliminating its effect on damaged heart cells.

"Our data show that slowing fibronectin polymerization preserves heart function, reduces left ventricular remodeling, and limits fibrous connective tissue formation," said Dr. Blaxal.

A key issue in the study was to test the results of targeted pUR4 molecular therapy in both mouse models and human cells suffering from heart failure.

Mice with simulated heart attack, which received placebo therapy as a control experiment, developed significant fibrosis and heart failure. In the first seven days of pUR4 treatment immediately after a heart attack, scientists were able to reduce fibrosis and improve heart function. Treatment of human heart cells with pUR4 also reduced fibrotic manifestations.
